Description

Technical Field

[0001] The utility model relates to a water treatment machine, in particular to a water treatment machine capable of performing multi-stage treatment on raw water (eg, tap water) to obtain treated water with expected water quality. The utility model further relates to a control valve for the water treatment machine. Background Art

[0002] In modern industrial production, many industries require water with high cleanliness or low hardness. However, the cleanliness and hardness of many water sources, whether surface water or groundwater, do not meet the standards for industrial water. In order to obtain water with the expected water quality, the water from the water source (or raw water) needs to be treated. To treat raw water, generally, the raw water from the water source is first coarsely filtered to filter out larger particulate pollutants to obtain coarsely filtered water, and then the coarsely filtered water is further filtered using materials such as activated carbon to obtain cleaner purified water. Finally, the purified water is softened (or ultrafiltration or RO membrane filtration) to obtain softened water (or purified water with extremely high purity). Finally, the raw water undergoes multi-stage treatment (two or more stages of treatment) to obtain treated water with the expected water quality. For example, people use water filtration equipment (filter materials are quartz sand, activated carbon or PP cotton filter materials, etc.) and water ultrafiltration equipment (filter materials are generally ultrafiltration membrane fibers) to filter and ultrafilter raw water in turn; or use water filtration equipment, water ultrafiltration equipment and RO membrane water purification equipment to filter, ultrafilter and RO membrane treat raw water in turn; or use pre-filter, water filtration equipment and water softener to coarse filter, filter and soften raw water in turn.

[0003] Furthermore, with rising living standards and a growing emphasis on health, people are demanding higher quality water for their daily lives. However, waterworks' extensive treatment of water from the source is insufficient to remove all impurities, such as particulate contaminants (flocculated gels, silt, and even bacteria), making it increasingly difficult to meet people's needs. Furthermore, the aging of the water supply network can introduce new contamination. Therefore, to further purify and improve the cleanliness of tap water, a variety of water treatment methods are required.

[0004] However, many existing water treatment systems or water treatment equipment that perform multi-stage treatment on raw water include multiple water treatment devices and multiple control valves that respectively control the flow of water inside the corresponding water treatment devices. Each control valve controls the water treatment function, flushing function, and regeneration function of the corresponding water treatment device. The multiple control valves of the water treatment system lead to high manufacturing costs and large space occupation. At the same time, since the control valve is a relatively complex device, the multiple control valves cause the failure rate of the entire water treatment system to be high. The Chinese invention patent with application number CN201910378852.7 discloses a water treatment system, which includes two water treatment devices and a flat valve for controlling the water treatment device to treat water, which can control the two water treatment devices to perform series purification-softening treatment on water. However, the planar valve 10 of the water treatment system provided by the patent has a low utilization rate of the flow control surfaces of its fixed valve plate 12 and the movable valve plate 13. The channels of the fixed valve plate 12 of the planar valve 10 are divided into two circles (except the central part), wherein the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105 and the sixth channel 106 are arranged in the inner circle, and the clean water channel 1030 and the soft water channel 1028 are arranged in the outer circle. Correspondingly, the channels of the movable valve plate 13 of the planar valve 10 are also divided into two circles, wherein the seventh channel 107 and the tenth channel 1010 are arranged in the inner circle, and the eighth channel 108 and the ninth channel 109 are arranged in the inner and outer circles. In particular, when the water treatment system provided by the patent is in the purification-softening working position, the seventh channel 107 and the tenth channel 1010 are arranged in the inner circle, and the eighth channel 108 and the ninth channel 109 are arranged in the inner and outer circles. The seventh channel 107 and the first channel 101 of the fixed valve plate 12 are the main water inlet channels, and only the inner circle area can be used as the water inlet channel. The ninth channel 109 is connected with the second channel 102 and the third channel 103 respectively, and plays the role of connecting the purification device and the softening device. Only the inner circle area of ​​the ninth channel 109 plays a conducting role. The eighth channel 108 is connected with the fourth channel 104 and the soft water channel 1028 respectively, and plays the role of conducting the supply of softened water, which is to divert the water from the inner circle channel to the outer circle channel. Therefore, the two-circle design of the channels of the fixed valve plate 12 and the movable valve plate 13 of the flat valve 10 provided by this patent makes the total area of ​​the flow control surface of the fixed valve plate and the movable valve plate too low, which greatly affects the water flow rate when the water treatment machine purifies and softens the raw water. In order to meet the required water flow rate through the multifunctional purification-softening valve, the valve's volume must be increased, resulting in a larger size and inconvenience. The larger size necessitates a thicker valve body wall to ensure valve stability under water pressure, which directly increases production costs. Furthermore, regardless of whether the multifunctional purification-softening valve's movable valve disc is made of metal or ceramic, overly large dimensions will result in a reduced yield during manufacturing. In particular, when the movable valve disc of the multifunctional purification-softening valve is made of ceramic, the larger its size, the more susceptible it is to cracking, and its service life is significantly reduced.Finally, the control valve of the water treatment machine disclosed in this invention patent adopts a traditional double valve plate structure, and at least one diversion blind hole needs to be set in the movable valve plate to provide treated water so that the flow direction of the water changes. For example, the softened water flows upward from the fourth channel 104 of the fixed valve plate 12, passes through the eighth channel 108 (diversion blind hole) of the movable valve plate 13, and then flows downward into the soft water channel 1028 of the fixed valve plate 12, and then flows out from the soft water port 1128 to supply water. It can be understood that when the water flows in the diversion blind hole (the eighth channel 108 of the movable valve plate 13), the flow direction changes 360 degrees, which will cause the water flow to be subject to greater resistance and cause a great loss of kinetic energy of the water flow, so that the flow rate of the water flow is significantly reduced.

More preferably, when the control valve 1 of the water treatment machine according to the present invention is controlled to the second backwash operating position, the flow of water in the first opening 1101 and the second opening 1102 is prevented, thereby preventing the flow of water within the first water treatment device 51. More specifically, when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the second backwash working position, water cannot flow from the first opening 1101 or the second opening 1102 of the first valve body 11 to the first water treatment device 51, thereby ensuring that raw water can and can only backwash the second water treatment device 52. It can be understood that when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the second backwash working position, the water treatment machine of the present invention is controlled to be in its second backwash working state to backwash the second water treatment device 52 of the water treatment machine of the present invention.

[0180] It can be understood that backwashing in this article refers to the flow direction of the water treatment device (the first water treatment device 51 or the second water treatment device 52) of the water treatment machine of the present invention when the water flow flushes the water treatment device of the water treatment machine of the present invention, and the flow direction of the raw water flowing through the water treatment device of the water treatment machine of the present invention is opposite to that when the water treatment device of the water treatment machine of the present invention treats the raw water.

[0181] As shown in the attached figure Figure 14A 、 Figure 14B and Figure 18DAs shown, the control valve 1 of the water treatment machine according to the first embodiment of the present invention has a regeneration working position, wherein when the control valve 1 of the water treatment machine of the present invention is in the regeneration working position, the valve core 12 of the control valve 1 forms a first regeneration flow channel 7301, a second regeneration flow channel 7302 and a third regeneration flow channel 7303, wherein the first regeneration flow channel 7301 is respectively connected to the second fluid opening 1106 and the first jet opening 11011 of the valve body 10, the second regeneration flow channel 7302 is respectively connected to the second jet opening 11012 and the third opening 1103, and the third regeneration flow channel 7303 is respectively connected to the sewage opening 1109 and the fourth opening 1104.

After the ejection of the ejector 18, the salt solution (such as sodium chloride solution) from the salt absorption port 181 is mixed to form a regeneration solution. The regeneration solution passes through the ejection port 18 of the ejector 18. 83 flows into the second jet opening 11012 of the first valve body 11, then flows into the third opening 1103 of the first valve body 11 through the second regeneration flow channel 7302. The regeneration solution flows into the second water treatment device 52 from the second water inlet 521, regenerating the second water treatment material 525 downstream, such as after softening the resin.

More preferably, when the control valve 1 of the water treatment machine of the present invention is controlled to be in the regeneration working position, the flow of water in the first opening 1101 and the second opening 1102 is blocked, thereby blocking the flow of water in the first water treatment device 51. More specifically, when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the regeneration working position, water cannot flow from the first opening 1101 or the second opening 1102 of the first valve body 11 to the first water treatment device 51, thereby ensuring that the regeneration solution can and can only flow to the second water treatment device 52.The term "downstream regeneration" herein means that, when in the regeneration operating position, the regeneration solution flows in the second water treatment device 52 in the same direction as the water flows in the second water treatment device 52 when the control valve 1 is in the water treatment operating position. It will be understood that when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the regeneration operating state, the water treatment machine of the present invention is controlled to be in its regeneration operating state.

Accordingly, when the control valve 1 is in the water replenishment position, raw water, under the action of water pressure, flows from the second fluid opening 1106 of the valve body 10 of the control valve 1, flows through the water replenishment flow channel 7401 to the second jet opening 11012 of the first valve body 11, and then flows into the regeneration solution tank 31 through the injection port 183 of the ejector 18, the salt absorption port 181, and the salt absorption pipe 184 in sequence to replenish water. Preferably, the control valve 1 of the water treatment machine according to the first embodiment of the present invention is configured to prevent raw water from flowing from the second fluid opening 1106 of the valve body 10 of the control valve 1 to the first opening 1101, the second opening 1102, the third opening 1103, the fourth opening 1104, and the first jet opening 11011 when the control valve 1 is controlled to the water replenishment operating position. More preferably, when the control valve 1 of the water treatment machine according to the present invention is controlled to the water replenishment operating position, the flow of water in the first opening 1101, the second opening 1102, the third opening 1103, and the fourth opening 1104 is prevented, thereby preventing the flow of water in the first water treatment device 51 and the second water treatment device 52. More specifically, when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the water replenishment working position, water cannot flow from the first opening 1101 or the second opening 1102 of the first valve body 11 to the first water treatment device 51, and water cannot flow from the third opening 1103 or the fourth opening 1104 of the first valve body 11 to the second water treatment device 52. It can be understood that when the control valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the water replenishment working position, the water treatment machine of the present invention is controlled to be in its water replenishment working state.

[0187] As shown in the attached figure Figures 5 to 8CAs shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model has a first channel 101, a second channel 102, a third channel 103, a fourth channel 104, a fifth channel 105, a sixth channel 106, a seventh channel 107, an eighth channel 108, a ninth channel 109, a first jet channel 1011 and a second jet channel 1012, wherein the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the first jet channel 1011 and the second jet channel 1012 are respectively provided on the first fixed valve plate 121 and extend from the first fluid control surface 1210 of the first fixed valve plate 121; the sixth channel 106, the seventh channel 107 and the eighth channel 108 are respectively provided on the movable valve plate 122, wherein the sixth channel 106 and the seventh channel 107 are respectively extended from the second fluid control surface 1210 of the movable valve plate 122. 20 extends, the eighth channel 108 extends from the second fluid control surface 1220 of the movable valve plate 122 to the third fluid control surface 1223; the fifth channel 105 and the ninth channel 109 are respectively provided on the second fixed valve plate 123 and respectively extend from the fourth fluid control surface 1230 of the second fixed valve plate 123, wherein the first channel 101 is connected to the first opening 1101, the second channel 102 is connected to the second opening 1102, and the third channel 10 3 is connected to the third opening 1103, the fourth channel 104 is connected to the fourth opening 1104, the fifth channel 105 is connected to the first fluid opening 1105, the sixth channel 106 is connected to the second fluid opening 1106, the ninth channel 109 is connected to the sewage discharge opening 1109, the first jet channel 1011 is connected to the first jet opening 11011, and the second jet channel 1012 is connected to the second jet opening 11012. Preferably, the seventh channel 107 is a conductive blind hole. Preferably, the eighth channel 108 is a conductive through hole. Preferably, the sixth channel 106 is connected to the valve chamber 110 and further connected to the second fluid opening 1106 through the valve chamber 110.

[0188] As shown in the attached figure Figure 10A 、 Figure 10B 、 Figure 11A 、 Figure 11B and Figure 18AAs shown, according to the first embodiment of the present invention, the movable valve disc 122 of the plane valve 1 of the water treatment machine can rotate relative to the first fixed valve disc 121 and the second fixed valve disc 123 so that the plane valve 1 has a water treatment working position. When the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, the sixth channel 106 of the plane valve 1 is connected to the first channel 101, thereby forming channels connected to the second fluid opening 1106 and the first opening 1101 respectively. The first water treatment channel 7001 and the seventh channel 107 are respectively connected to the second channel 102 and the third channel 103, thereby forming the second water treatment channel 7002 respectively connected to the second opening 1102 and the third opening 1103, and the eighth channel 108 is respectively connected to the fourth channel 104 and the fifth channel 105, thereby forming the third water treatment channel 7003 respectively connected to the fourth opening 1104 and the first fluid opening 1105. In other words, when the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, the water flows under the action of water pressure in sequence through the second fluid opening 1106 of the plane valve 1, the sixth channel 106, the first channel 101, the first opening 1101, the first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second opening 1102 of the plane valve 1, the second channel 102, the seventh channel 107, the third channel 103, the third opening 1103, the second water inlet 521 of the second water treatment device 52, the second water outlet 522 of the second water treatment device 52, the fourth opening 1104 of the plane valve 1, the fourth channel 104, the eighth channel 108, the fifth channel 105 and the first fluid opening 1105. As shown in the accompanying drawings 7A to 7I 、 Figure 10A 、 Figure 10B and Figure 18A As shown, exemplarily, when the plane valve 1 of the water treatment machine of the utility model is in the water treatment working position, the first jet channel 1011 and the second jet channel 1012 of the plane valve 1 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth channel 109 is blocked by the third fluid control surface 1223 of the movable valve plate 122.

[0189] It is worth noting that when the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, the seventh channel 107 is connected to the second channel 102 and the third channel 103 respectively. That is to say, when the plane valve 1 is in the water treatment working position, the second opening 1102 and the third opening 1103 are connected through the second water treatment flow channel 7002. Since the second opening 1102 is connected to the first water outlet 512 of the first water treatment device 51, and the third opening 1103 is connected to the second water inlet 521 of the second water treatment device 52, at this time, The first water outlet 512 of the first water treatment device 51 and the second water inlet 521 of the second water treatment device 52 form a series structure, so that when the plane valve 1 is in the water treatment working position, the first water treatment device 51 and the second water treatment device 52 form a two-stage series structure. The first water treatment material 515 of the first water treatment device 51 and the second water treatment material 525 of the second water treatment device 52 will sequentially treat the raw water entering the second fluid opening 1106 of the plane valve 1, and the treated water flows out of the first fluid opening 1105 and is provided. It can be understood that the two-stage series structure can better perform deep treatment on the raw water. In particular, the first water treatment material 515 of the first water treatment device 51 and the second water treatment material 525 of the second water treatment device 52 can be set to different materials. For example, the first water treatment material 515 can be set to granular activated carbon as an adsorption material, and the second water treatment material 525 can be set to softening resin for softening treatment.

[0190] As shown in the attached figure Figure 11A 、 Figure 11B and Figure 18AAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the water treatment working position, the raw water from the plane valve 1 flows into the valve cavity 110 from the second fluid opening 1106 of the valve body 10 under the action of water pressure, and then flows into the first opening 1101 through the sixth channel 106 and the first channel 101, and then flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51. Under the action of water pressure, the first-level treated water is treated (for example, purified) by the first water treatment material 515, and the generated primary treated water is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51. Under the action of water pressure, the first-level treated water The treated water further flows through the second opening 1102, the second channel 102, the seventh channel 107, the third channel 103, and the third opening 1103 of the plane valve 1 to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52, and then is treated (for example, softened) by the second water treatment material 525 under the action of water pressure. The generated secondary treated water is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and then is further provided through the fourth opening 1104, the fourth channel 104, the eighth channel 108, the fifth channel 105 and the first fluid opening 1105 of the plane valve 1 under the action of water pressure.

[0191] As shown in the attached figure Figure 10C 、 Figure 10D 、 Figure 12 and Figure 18B As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a first backwash working position. When the plane valve 1 of the water treatment machine of the present invention is in the first backwash working position, the sixth channel 106 of the plane valve 1 is connected with the second channel 102, thereby forming the first backwash flow channel 7101 connected with the second fluid opening 1106 and the second opening 1102 respectively, and the eighth channel 108 is connected with the ninth channel 109 and the first channel 101 respectively, thereby forming the second backwash flow channel 7102 connected with the sewage opening 1109 and the first opening 1101 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10C 、 Figure 10D and Figure 18BAs shown, when the plane valve 1 of the water treatment machine of the utility model is in the first backwash working position, the seventh channel 107 of the plane valve 1 is respectively connected to the first channel 101 and the fourth channel 104, the third channel 103, the first jet channel 1011 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 is in the first backwash working position, although the seventh channel 107 of the plane valve 1 is connected to the first channel 101 and the fourth channel 104 respectively, the seventh channel 107 is a conducting blind hole, and the third channel 103, the first jet channel 1011 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the sixth channel 106 from the second fluid opening 1106 of the plane valve 1, and The wastewater further flows through the second channel 102 and the second opening 1102 to the first water outlet 512 of the first water treatment device 51 and into the first water treatment device 51. The wastewater generated by backwashing the first water treatment device 51 flows from the first water inlet 511 of the first water treatment device 51 to the first opening 1101 of the plane valve 1 and is further discharged through the first channel 101, the eighth channel 108, the ninth channel 109, and the sewage opening 1109 of the plane valve 1 under the action of water pressure. In other words, although the seventh channel 107 is connected to the first channel 101 and the fourth channel 104 respectively, the seventh channel 107 is a conducting blind hole, and the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Therefore, water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the first backwash working position, the third channel 103 of the planar valve 1 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the third opening 1103 of the planar valve 1, so that the flow of water from the second water inlet 521 of the second water treatment device 52 to the third opening 1103 is blocked, and the flow of water from the fourth opening 1104 to the second water outlet 522 of the second water treatment device 52 is blocked, so that no water flows in the fourth opening 1104, and therefore, the flow of water in the second water treatment device 52 is blocked. In other words, although the seventh channel 107 is connected to the first channel 101 and the fourth channel 104 respectively, so that the first opening 1101 and the fourth opening 1104 are connected, the movable valve plate 122 blocks the water flow to the third channel 103, so that the flow of water in the second water treatment device 52 is blocked, thereby ensuring that only the first water treatment device 51 is reverse flushed.

[0192] It is noteworthy that when the planar valve 1 is in the first backwash working position, the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the third opening 1103, resulting in no water flowing in the fourth opening 1104 and no water flowing in the second water treatment device 52. This ensures that only the first water treatment device 51 is backwashed, thereby increasing the intensity of the raw water flow backwashing the first water treatment device 51 while preventing the generated sewage from flowing into the second water treatment device 52. Therefore, when the planar valve 1 is in the first backwash working position, the first water treatment device 51 of the water treatment machine of the present invention is backwashed alone.

[0193] As shown in the attached figure Figure 12 and Figure 18B As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the first backwash working position, the raw water from the plane valve 1 flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, and then flows from the first central pipe 514 to the first water treatment material 515 and backwashes the first water treatment material 515 under the action of water pressure. The generated sewage flows out from the first water inlet 511 of the first water treatment device 51, and under the action of water pressure, flows to the first opening 1101 of the plane valve 1, and then flows to the sewage opening 1109 through the second backwash channel 7102 and is discharged.

[0194] As shown in the attached figure Figure 10E 、 Figure 10F 、 Figure 13 and Figure 18C As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a second backwash working position. When the plane valve 1 of the water treatment machine of the present invention is in the second backwash working position, the sixth channel 106 of the plane valve 1 is connected with the fourth channel 104, thereby forming the third backwash flow channel 7103 connected with the second fluid opening 1106 and the fourth opening 1104 respectively, and the eighth channel 108 is connected with the ninth channel 109 and the third channel 103 respectively, thereby forming the fourth backwash flow channel 7104 connected with the sewage opening 1109 and the third opening 1103 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10E 、 Figure 10F and Figure 18CAs shown, when the plane valve 1 of the water treatment machine of the present invention is in the second backwash working position, the seventh channel 107 of the plane valve 1 is connected to the first channel 101 and the first jet channel 1011 respectively, the second channel 102 and the second jet channel 1012 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10E 、 Figure 10F and Figure 18C As shown, specifically, when the plane valve 1 is in the second backwash working position, although the seventh channel 107 is connected to the first channel 101 and the first jet channel 1011 respectively, since the seventh channel 107 is a conducting blind hole, and the second channel 102 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the raw water can only flow into the sixth channel 106 from the second fluid opening 1106 of the plane valve 1, and further through the The fourth channel 104 and the fourth opening 1104 flow toward the second water outlet 522 of the second water treatment device 52 and into the second water treatment device 52. Wastewater generated by backwashing the second water treatment device 52 flows from the second water inlet 521 of the second water treatment device 52 toward the third opening 1103 of the planar valve 1 and, under the action of water pressure, is further discharged through the third channel 103, the eighth channel 108, the ninth channel 109, and the sewage opening 1109 of the planar valve 1. In other words, although the seventh channel 107 of the planar valve 1 is connected to the first channel 101 and the first jet channel 1011, respectively, the seventh channel 107 is a conducting blind hole, and the second channel 102 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122. Therefore, water does not flow through the flow channel formed by them. Therefore, when the planar valve 1 is in the second backwash working position, the second channel 102 of the planar valve 1 is blocked by the second fluid control surface 1220 of the movable valve disc 122, thereby preventing water from flowing through the second opening 1102 of the planar valve 1. Furthermore, because water does not flow through the flow channel formed by the seventh channel 107 connecting with the first channel 101 and the first jet channel 1011, no water flows through the first opening 1101, thereby preventing the flow of water in the first water treatment device 51. In other words, although the seventh channel 107 is connected with the first channel 101 and the first jet channel 1011, the movable valve disc 122 blocks the flow of raw water to the second channel 102, preventing the flow of water in the first water treatment device 51, thereby ensuring that only the second water treatment device 52 is backwashed.

[0195] It is noteworthy that when the flat valve 1 is in the second backwash working position, the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the second opening 1102. Although the seventh channel 107 of the flat valve 1 is respectively connected to the first channel 101 and the first jet channel 1011, water does not flow through the flow channel formed by them, so that no water flows in the first opening 1101, isolating the first water treatment device 51 from the water flow, ensuring that only the second water treatment device 52 is backwashed, thereby increasing the intensity of the raw water backwashing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51. Therefore, when the flat valve 1 is in the second backwash working position, the second water treatment device 52 of the water treatment machine of the present invention is backwashed separately.

[0196] As shown in the attached figure Figure 13 and Figure 18C As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the second backwash working position, the raw water from the plane valve 1 flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, and then flows from the second central pipe 524 to the second water treatment material 525 and backwashes the second water treatment material 525 under the action of water pressure. The generated sewage flows out from the second water inlet 521 of the second water treatment device 52, and under the action of water pressure, flows to the third opening 1103 of the first valve body 11 of the plane valve 1, and then flows to the sewage opening 1109 through the fourth backwash channel 7104 and is discharged.

[0197] As shown in the attached figure Figure 10G 、 Figure 10H 、 Figure 14A 、 Figure 14B and Figure 18D As shown, the flat valve 1 of the water treatment machine according to the first embodiment of the present invention further has a regeneration working position. When the flat valve 1 is in the regeneration working position, the sixth channel 106 of the flat valve 1 is connected to the first jet channel 1011, thereby forming the first regeneration flow channel 7301 connected to the second fluid opening 1106 and the first jet opening 11011 respectively. The seventh channel 107 is connected to the second jet channel 1012 and the third channel 103 respectively, thereby forming the second regeneration flow channel 7302 connected to the second jet opening 11012 and the third opening 1103 respectively. The eighth channel 108 is connected to the ninth channel 109 and the fourth channel 104 respectively, thereby forming the third regeneration flow channel 7303 connected to the sewage opening 1109 and the fourth opening 1104 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10G 、 Figure 10H and Figure 18D As shown, when the planar valve 1 is in the regeneration working position, the first channel 101 and the second channel 102 of the planar valve 1 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 of the water treatment machine of the present invention is in the regeneration working position, the raw water flows into the second fluid opening 1106 of the valve body 10 of the plane valve 1 under the action of water pressure, flows through the first regeneration flow channel 7301 (the sixth channel 106 and the first jet channel 1011) to the first jet opening 11011 of the first valve body 11, and then flows into the ejection port 182 of the ejector 18. After the ejection of the ejector 18, the salt solution (such as sodium chloride solution) from the salt absorption port 181 is mixed to form a regeneration solution. The regeneration solution flows into the second jet opening 11011 of the first valve body 11 through the ejection port 183 of the ejector 18. The regeneration solution flows from the second water inlet 521 into the second water treatment device 52, and then flows through the second regeneration channel 7302 (the second jet channel 1012, the seventh channel 107 and the third channel 103) to the third opening 1103 of the first valve body 11. The regeneration solution flows from the second water inlet 521 into the second water treatment device 52, and regenerates the second water treatment material 525 downstream. After softening the resin, the waste water generated after regeneration flows out from the second water outlet 522, and then flows out through the fourth opening 1104 of the first valve body 11, the third regeneration channel 7303 (the fourth channel 104, the eighth channel 108 and the ninth channel 109) and the sewage outlet 1109 in sequence. As shown in the accompanying drawings, 7A to 7I 、 Figure 10G 、 Figure 10H and Figure 18DAs shown, specifically, when the plane valve 1 is in the regeneration working position, the first channel 101 and the second channel 102 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the sixth channel 106 from the second fluid opening 1106 of the plane valve 1, and further sequentially through the first jet channel 1011, the first jet opening 11011, the ejector 18, the second jet opening 11012, the second jet channel 1012, the seventh channel 107, the third channel 108, the seventh channel 109, the seventh channel 1109, the seventh channel 1110, the seventh channel 1 ... The wastewater flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the plane valve 1, and is further discharged through the fourth channel 104, the eighth channel 108, the ninth channel 109 and the sewage opening 1109 of the plane valve 1 under the action of water pressure. Correspondingly, when the planar valve 1 is in the regeneration working position, the first channel 101 and the second channel 102 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the first opening 1101 and the second opening 1102 of the planar valve 1, so that the flow of water from the first opening 1101 to the first water inlet 511 of the first water treatment device 51 is blocked, the flow of water from the second opening 1102 to the first water outlet 512 of the first water treatment device 51 is blocked, and the flow of water in the first water treatment device 51 is blocked, thereby ensuring that only the second water treatment device 52 is regenerated downstream.

[0198] It is worth noting that when the planar valve 1 is in the regeneration working position, the first channel 101 and the second channel 102 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the first opening 1101 and the second opening 1102 are both blocked by the movable valve plate 122, so that the first water treatment device 51 is isolated from the water flow to ensure that only the second water treatment device 52 is regenerated downstream, thereby increasing the intensity of the water flow of the regeneration solution for downstream regeneration of the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. In particular, it is necessary to prevent the regeneration salt solution (or the sewage wastewater after the regeneration resin, because the sewage wastewater has a high salt content) from entering the first water treatment device 51. Because in actual use, the first water treatment device 51 is often other adsorbent filter materials such as activated carbon, the regeneration salt solution will contaminate the activated carbon and other filter materials, thereby weakening the purification capacity of the first water treatment device 51. This is also a major reason why multi-stage purification and softening water treatment equipment cannot simply use the activated carbon water treatment device and the softening resin water treatment device directly in series. Therefore, when the flat valve 1 is in the regeneration working position, the second water treatment device 52 of the water treatment machine of the present invention is regenerated separately downstream.

[0199] As shown in the attached figure Figure 14A 、 Figure 14B and Figure 18D As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the regeneration working position, the raw water from the plane valve 1 is mixed with the salt solution from the ejector 18 under the action of water pressure to form a regeneration solution, which flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52, and then regenerates the second water treatment material 525 downstream under the action of water pressure. The generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and under the action of water pressure, flows to the fourth opening 1104 of the plane valve 1, and then flows to the sewage opening 1109 through the third regeneration flow channel 7303 and is discharged.

[0200] As shown in the attached figure Figure 10I 、 Figure 10J 、 Figure 15 and Figure 18EAs shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a first positive flushing working position. When the plane valve 1 of the water treatment machine of the present invention is in the first positive flushing working position, the sixth channel 106 of the plane valve 1 is connected with the first channel 101, thereby forming the first positive flushing flow channel 7201 connected with the second fluid opening 1106 and the first opening 1101 respectively, and the eighth channel 108 is connected with the ninth channel 109 and the second channel 102 respectively, thereby forming the second positive flushing flow channel 7202 connected with the sewage opening 1109 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10I 、 Figure 10J and Figure 18E As shown, when the plane valve 1 of the water treatment machine of the present invention is in the first positive flushing working position, the seventh channel 107 of the plane valve 1 is connected to the third channel 103 and the second jet channel 1012 respectively, the fourth channel 104 and the first jet channel 1011 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10I 、 Figure 10J and Figure 18EAs shown, when the plane valve 1 is in the first positive flushing working position, although the seventh channel 107 of the plane valve 1 is connected to the third channel 103 and the second jet channel 1012 respectively, the seventh channel 107 is a conducting blind hole, and the fourth channel 104 and the first jet channel 1011 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the sixth channel 106 from the second fluid opening 1106 of the plane valve 1, and further through the The wastewater generated by the first channel 101 and the first opening 1101 flows toward the first water inlet 511 of the first water treatment device 51 and into the first water treatment device 51, and the wastewater generated by forward flushing the first water treatment device 51 flows from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the planar valve 1, and is further discharged through the second channel 102, the eighth channel 108, the ninth channel 109, and the sewage opening 1109 of the planar valve 1 under the action of water pressure. In other words, although the seventh channel 107 of the planar valve 1 is connected to the third channel 103 and the second jet channel 1012, respectively, because the seventh channel 107 is a conducting blind hole and the fourth channel 104 and the first jet channel 1011 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the water does not flow through the flow channel formed by them. Accordingly, when the planar valve 1 is in the first forward flushing position, the fourth channel 104 is blocked by the second fluid control surface 1220 of the movable valve disc 122, thereby preventing water from flowing through the fourth opening 1104 of the planar valve 1. Consequently, water from the fourth opening 1104 to the second water outlet 522 of the second water treatment device 52 is blocked. Furthermore, because water does not flow through the flow path formed by the seventh channel 107, which is connected to the third channel 103 and the second jet channel 1012, no water flows through the third opening 1103. Consequently, water flow in the second water treatment device 52 is blocked. In other words, although the seventh channel 107 is connected to the third channel 103 and the second jet channel 1012, the movable valve disc 122 blocks the flow of raw water to the fourth channel 104, preventing water from flowing in the second water treatment device 52. This ensures that only the first water treatment device 51 is reverse flushed.

[0201] It is noteworthy that when the flat valve 1 is in the first positive flushing working position, the fourth channel 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the fourth opening 1104. Although the seventh channel 107 of the flat valve 1 is respectively connected to the third channel 103 and the second jet channel 1012, water does not flow through the flow channel formed by them, so that no water flows in the third opening 1103, isolating the second water treatment device 52 from the water flow, and ensuring that only the first water treatment device 51 is positively flushed. This increases the intensity of the raw water flow for positively flushing the first water treatment device 51 while preventing the generated sewage from flowing into the second water treatment device 52. Therefore, when the flat valve 1 is in the first positive flushing working position, the first water treatment device 51 of the water treatment machine of the present invention is positively flushed alone.

[0202] As shown in the attached figure Figure 15 and Figure 18E As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the first positive flushing working position, the raw water from the plane valve 1 flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then positively flushes the first water treatment material 515 under the action of water pressure. The generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, and flows to the second opening 1102 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 1109 through the second positive flushing channel 7202 and is discharged.

[0203] As shown in the attached figure Figure 10K 、 Figure 10L 、 Figure 16 and Figure 18F As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a second positive flushing working position. When the plane valve 1 of the water treatment machine of the present invention is in the second positive flushing working position, the sixth channel 106 of the plane valve 1 is connected with the third channel 103, thereby forming the third positive flushing flow channel 7203 connected with the second fluid opening 1106 and the third opening 1103 respectively, and the eighth channel 108 is connected with the ninth channel 109 and the fourth channel 104 respectively, thereby forming the fourth positive flushing flow channel 7204 connected with the sewage opening 1109 and the fourth opening 1104 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10K 、 Figure 10L and Figure 18FAs shown, when the plane valve 1 of the water treatment machine of the present invention is in the second positive flushing working position, the seventh channel 107 of the plane valve 1 is connected to the second channel 102 and the fourth channel 104 respectively, the first channel 101, the first jet channel 1011 and the second jet channel 1012 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10K 、 Figure 10L and Figure 18F As shown, specifically, when the plane valve 1 is in the second positive flushing working position, although the seventh channel 107 of the plane valve 1 is connected to the second channel 102 and the fourth channel 104 respectively, the seventh channel 107 is a conducting blind hole, and the first channel 101, the first jet channel 1011 and the second jet channel 1012 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the sixth channel 101 from the second fluid opening 1106 of the plane valve 1. 6, and further flows through the third channel 103 and the third opening 1103 to the second water inlet 521 of the second water treatment device 52 and into the second water treatment device 52. The wastewater generated by forward flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the plane valve 1, and is further discharged through the fourth channel 104, the eighth channel 108, the ninth channel 109, and the sewage opening 1109 of the plane valve 1 under the action of water pressure. In other words, although the seventh channel 107 is connected to the second channel 102 and the fourth channel 104 respectively, because the seventh channel 107 is a conductive blind hole and the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, water does not flow through the flow channel formed by them. Accordingly, when the planar valve 1 is in the second positive flushing position, the first channel 101 of the planar valve 1 is blocked by the second fluid control surface 1220 of the movable valve disc 122, thereby preventing water from flowing through the first opening 1101 of the planar valve 1. Consequently, water is prevented from flowing from the first water inlet 511 of the first water treatment device 51 to the first opening 1101, resulting in no water flowing through the second opening 1102. Consequently, the flow of water in the first water treatment device 51 is blocked. In other words, the seventh channel 107 is connected to the second channel 102 and the fourth channel 104, respectively. However, because the movable valve disc 122 obstructs water from flowing to the first channel 101, the flow of water in the first water treatment device 51 is blocked, thereby ensuring that only the second water treatment device 52 is positively flushed.

[0204] It is noteworthy that when the flat valve 1 is in the second positive flushing position, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the first opening 1101. As a result, no water flows through the second opening 1102, and no water flows through the first water treatment device 51. This ensures that only the second water treatment device 52 is positively flushed, thereby increasing the intensity of the raw water flow for positively flushing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51. Therefore, when the flat valve 1 is in the second positive flushing position, the second water treatment device 52 of the water treatment machine of the present invention is positively flushed alone.

[0205] As shown in the attached figure Figure 16 and Figure 18F As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the second positive flushing working position, the raw water from the plane valve 1 flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then positively flushes the second water treatment material 525 under the action of water pressure. The generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and flows to the fourth opening 1104 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 1109 through the fourth positive flushing channel 7204 and is discharged.

[0206] As shown in the attached figure Figure 10M 、 Figure 10N 、 Figure 17 and Figure 18G As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a water replenishment working position. When the plane valve 1 is in the water replenishment working position, the sixth channel 106 is connected to the second jet channel 1012, thereby forming the water replenishment flow channel 7401 connected to the second fluid opening 1106 and the second jet opening 11012 respectively. 7A to 7I 、 Figure 10M 、 Figure 10N and Figure 18GAs shown, when the planar valve 1 is in the water replenishing working position, the seventh channel 107 of the planar valve 1 is connected with the fourth channel 104, the eighth channel 108 is respectively connected with the ninth channel 109 and the first channel 101, the second channel 102, the third channel 103 and the first jet channel 1011 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the fifth channel 105 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 of the water treatment machine of the present invention is in the water replenishment working position, the raw water flows into the second fluid opening 1106 of the valve body 10 of the plane valve 1 under the action of water pressure, flows into the second jet opening 11012 through the sixth channel 106 and the second jet channel 1012, and then flows into the regeneration solution tank 31 through the injection port 183 of the ejector 18, the salt absorption port 181 and the salt absorption pipe 184 in sequence for water replenishment. Although the seventh channel 107 is connected to the fourth channel 104, the seventh channel 107 is a conductive blind hole, so that the fourth channel 104 is blocked by the movable valve plate 122. Although the eighth channel 108 is respectively connected to the ninth channel 109 and the first channel 101, the eighth channel 108 is a conductive through hole, and the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the ninth channel 109, the eighth channel 108, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102, and the second channel 102 form a flow channel isolated from the raw water, so that the water cannot flow through the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104. In other words, although the seventh channel 107 is connected to the fourth channel 104 and the eighth channel 108 is connected to the ninth channel 109 and the first channel 101 respectively, a flow channel for allowing water to flow through cannot be formed.

[0207] It is worth noting that the traditional flat valve adopts a valve core structure with a single movable valve plate and a single fixed valve plate. The movable valve plate often requires a water supply conducting blind hole (except for the conducting blind hole for conducting the second opening and the third opening) to guide the water flow to the outlet. When the water flows in the water supply guide blind hole, the flow direction changes 360 degrees, which will cause the water flow to be subject to greater resistance and cause a great loss of kinetic energy of the water flow, resulting in a significant reduction in the flow rate of the water flow. The flat valve 1 of the water treatment machine of the present invention adopts a three-valve plate structure. The water flow to the outlet flows upward from the lower valve plate (the first fixed valve plate 121), and the outlet is on the upper valve plate (the second fixed valve plate 123). The change in the direction of the water flow is small (roughly), and the water flow is subject to less resistance during the change of flow direction, and the loss of water flow is also significantly reduced. Furthermore, in existing planar valves with a single fixed valve disc, the channel for controlling the flow direction of water can only be set on the fixed valve disc. In order to achieve the corresponding functions of the planar valve, the channel of the fixed valve disc is divided into two circles (except for the center part), and the soft water channel (water outlet channel) is often set on the outer circle. Correspondingly, the channel of the movable valve disc is also set in two circles, resulting in the effective flow channel area accounting for too low a proportion of the total flow control surface area of ​​the entire fixed valve disc and the movable valve disc. In order to ensure the water flow rate, the diameters of the fixed valve disc and the movable valve disc of the planar valve are large, and the volume of the entire planar valve is large. The larger the diameter of the planar valve, the more difficult it is to ensure the stability of the movable valve disc when it rotates. In order to ensure the stability of the entire planar valve, the cross-sectional area of ​​the planar valve becomes larger, and the valve body needs to have a thicker wall thickness. Since the diameter of the movable valve disc increases accordingly, the thickness of the movable valve disc also needs to increase accordingly. This not only increases the manufacturing cost of the planar valve, but also makes the entire planar valve more bulky and difficult to operate. The first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the ninth channel 109, the first jet channel 1011 and the second jet channel 1012 of the plane valve 1 of the water treatment machine of the present invention are respectively arranged on the first fixed valve plate 121 and the second fixed valve plate 123, and are arranged in a single circle. The sixth channel 106, the seventh channel 107 and the eighth channel 108 are respectively arranged on the movable valve plate 122, and are also arranged in a single circle, thereby allowing the space occupied by each channel arranged on the fixed valve plate and the movable valve plate to be larger and increasing the water flow rate.In other words, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the ninth channel 109, the first jet channel 1011 and the second jet channel 1012 of the plane valve 1 of the water treatment machine of the present invention are respectively arranged in a single circle on the first fixed valve plate 121 and the second fixed valve plate 123, and the sixth channel 106, the seventh channel 107 and the eighth channel 108 are respectively arranged in a single circle on the movable valve plate 122, which can significantly reduce the diameter of the fixed and movable valve plates of the plane valve (or the inner diameter of the valve cavity), the thickness of the movable valve plate and the wall thickness of the valve body, thereby reducing the manufacturing cost of the plane valve and making the entire plane valve structure lighter and easier to operate.

[0208] As shown in the attached figure Figures 6C to 10NAs shown, the first channel 101 of the planar valve 1 of the water treatment machine according to the first embodiment of the present utility model has a first communicating portion 10101 and a second communicating portion 10102, wherein the first communicating portion 10101 of the first channel 101 is connected to the first opening 1101, and the second communicating portion 10102 of the first channel 101 is connected to the first opening 1101.

The first water treatment channel 7001B, the seventh channel 107B is respectively connected to the second channel 102B and the third channel 103B, thereby forming the second water treatment channel 7002B respectively connected to the second opening 1102B and the third opening 1103B, the eighth channel 108B is respectively connected to the fourth channel 104B and the fifth channel 105B, thereby forming the third water treatment channel 7003B respectively connected to the fourth opening 1104B and the first fluid opening 1105B. In other words, when the plane valve 1B of the water treatment machine of the present invention is in the water treatment working position, the water flows under the action of water pressure in sequence through the second fluid opening 1106B of the plane valve 1B, the sixth channel 106B, the first channel 101B, the first opening 1101B, the first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second opening 1102B of the plane valve 1B, the second channel 102B, the seventh channel 107B, the third channel 103B, the third opening 1103B, the second water inlet 521 of the second water treatment device 52, the second water outlet 522 of the second water treatment device 52, the fourth opening 1104B of the plane valve 1B, the fourth channel 104B, the eighth channel 108B, the fifth channel 105B and the first fluid opening 1105B. As shown in the accompanying drawings Figures 26A to 26I 、 Figure 29A 、 Figure 29B and Figure 37A As shown, exemplarily, when the plane valve 1B of the water treatment machine of the utility model is in the water treatment working position, the first jet channel 1011B and the second jet channel 1012B of the plane valve 1B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the ninth channel 109B is blocked by the third fluid control surface 1223B of the movable valve plate 122B.

[0246] It is worth noting that when the plane valve 1B of the water treatment machine of the present invention is in the water treatment working position, the seventh channel 107B is connected to the second channel 102B and the third channel 103B respectively. That is to say, when the plane valve 1B is in the water treatment working position, the second opening 1102B and the third opening 1103B are connected through the second water treatment flow channel 7002B. Since the second opening 1102B is connected to the first water outlet 512 of the first water treatment device 51, and the third opening 1103B is connected to the second water inlet 521 of the second water treatment device 52, At this time, the first water outlet 512 of the first water treatment device 51 and the second water inlet 521 of the second water treatment device 52 form a series structure, so that when the plane valve 1B is in the water treatment working position, the first water treatment device 51 and the second water treatment device 52 form a two-stage series structure. The first water treatment material 515 of the first water treatment device 51 and the second water treatment material 525 of the second water treatment device 52 will sequentially treat the raw water entering the second fluid opening 1106B of the plane valve 1B, and the treated water flows out from the first fluid opening 1105B and is provided. It can be understood that the two-stage series structure can better perform deep treatment on raw water. In particular, the first water treatment material 515 of the first water treatment device 51 and the second water treatment material 525 of the second water treatment device 52 can be set to different materials. For example, the first water treatment material 515 can be set to granular activated carbon as the adsorption material, and the second water treatment material 525 can be set to softening resin for softening treatment.

[0247] As shown in the attached figure Figure 30A 、 Figure 30B and Figure 37AAs shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the water treatment working position, the raw water from the plane valve 1B flows into the valve cavity 110B from the second fluid opening 1106B of the valve body 10B under the action of water pressure, and then flows into the first opening 1101B through the sixth channel 106B and the first channel 101B, and then flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51. Under the action of water pressure, after being treated (for example, purified) by the first water treatment material 515, the generated primary treated water is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51. Under the action of water pressure, the primary treated water It further flows through the second opening 1102B, the second channel 102B, the seventh channel 107B, the third channel 103B, and the third opening 1103B of the plane valve 1B to the second water inlet 521 of the second water treatment device 52 and into the second water treatment device 52, and then under the action of water pressure, it is treated (for example, softened) by the second water treatment material 525, and the generated secondary treated water is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and then under the action of water pressure, it is further provided through the fourth opening 1104B, the fourth channel 104B, the eighth channel 108B, the fifth channel 105B and the first fluid opening 1105B of the plane valve 1B.

[0248] As shown in the attached figure Figure 29C 、 Figure 29D 、 Figure 31 and Figure 37B As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the present invention further has a first backwash working position. When the plane valve 1B of the water treatment machine of the present invention is in the first backwash working position, the sixth channel 106B of the plane valve 1B is connected to the second channel 102B, thereby forming the first backwash flow channel 7101B connected to the second fluid opening 1106B and the second opening 1102B respectively, and the eighth channel 108B is connected to the ninth channel 109B and the first channel 101B respectively, thereby forming the second backwash flow channel 7102B connected to the sewage opening 1109B and the first opening 1101B respectively. As shown in the accompanying drawings 26A to 26I 、 Figure 29C 、 Figure 29D and Figure 37BAs shown, when the plane valve 1B of the water treatment machine of the utility model is in the first backwash working position, the seventh channel 107B of the plane valve 1B is respectively connected to the second channel 102B and the fourth channel 104B, the third channel 103B, the first jet channel 1011B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fifth channel 105B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. Therefore, when the plane valve 1B is in the first backwash working position, although the seventh channel 107B of the plane valve 1B is connected to the second channel 102B and the fourth channel 104B respectively, the seventh channel 107B is a conducting blind hole, and the third channel 103B, the first jet channel 1011B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that the raw water can only flow into the sixth channel 106B from the second fluid opening 1106B of the plane valve 1B. B, and further flows through the second channel 102B and the second opening 1102B to the first water outlet 512 of the first water treatment device 51 and into the first water treatment device 51. The wastewater generated by backwashing the first water treatment device 51 flows from the first water inlet 511 of the first water treatment device 51 to the first opening 1101B of the plane valve 1B, and is further discharged through the first channel 101B, the eighth channel 108B, the ninth channel 109B, and the sewage opening 1109B of the plane valve 1B under the action of water pressure. In other words, although the seventh channel 107B is connected to the second channel 102B and the fourth channel 104B respectively, the seventh channel 107B is a conductive blind hole, and the third channel 103B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, so the water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1B is in the first backwash working position, the third channel 103B of the planar valve 1B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the third opening 1103B of the planar valve 1B, so that the flow of water from the second water inlet 521 of the second water treatment device 52 to the third opening 1103B is blocked, and the flow of water from the fourth opening 1104B to the second water outlet 522 of the second water treatment device 52 is blocked, so that no water flows in the fourth opening 1104B, and therefore, no water flows in the second water treatment device 52. In other words, although the seventh channel 107B is connected to the second channel 102B and the fourth channel 104B respectively, the flow of water in the second water treatment device 52 is blocked because the movable valve plate 122B blocks the flow of water to the third channel 103B, thereby ensuring that only the first water treatment device 51 is reverse flushed.

[0249] It is noteworthy that when the planar valve 1B is in the first backwash operating position, the third channel 103B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the third opening 1103B. This results in no water flowing through the fourth opening 1104B, and consequently, no water flowing through the second water treatment device 52. This ensures that only the first water treatment device 51 is backwashed, thereby increasing the intensity of the raw water backwashing the first water treatment device 51 while preventing the generated wastewater from flowing into the second water treatment device 52. Therefore, when the planar valve 1B is in the first backwash operating position, the first water treatment device 51 of the water treatment machine of the present invention is backwashed alone.

[0250] As shown in the attached figure Figure 31 and Figure 37B As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the first backwash working position, the raw water from the plane valve 1B flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, and then flows from the first central pipe 514 to the first water treatment material 515 and backwashes the first water treatment material 515 under the action of water pressure. The generated sewage flows out from the first water inlet 511 of the first water treatment device 51, and under the action of water pressure, flows to the first opening 1101B of the plane valve 1B, and then flows to the sewage opening 1109B through the second backwash flow channel 7102B and is discharged.

[0251] As shown in the attached figure Figure 29E 、 Figure 29F 、 Figure 32 and Figure 37C As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the present invention further has a second backwash working position. When the plane valve 1B of the water treatment machine of the present invention is in the second backwash working position, the sixth channel 106B of the plane valve 1B is connected to the fourth channel 104B, thereby forming the third backwash flow channel 7103B connected to the second fluid opening 1106B and the fourth opening 1104B respectively, and the eighth channel 108B is connected to the ninth channel 109B and the third channel 103B respectively, thereby forming the fourth backwash flow channel 7104B connected to the sewage opening 1109B and the third opening 1103B respectively. As shown in the accompanying drawings 26A to 26I 、 Figure 29E 、 Figure 29F and Figure 37CAs shown, when the plane valve 1B of the water treatment machine of the present invention is in the second backwash working position, the seventh channel 107B of the plane valve 1B is connected to the first channel 101B and the second jet channel 1012B respectively, the second channel 102B and the first jet channel 1011B are blocked by the second fluid control surface 1220B of the movable valve plate 122B respectively, and the fifth channel 105B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. 26A to 26I 、 Figure 29E 、 Figure 29F and Figure 37CSpecifically, when the plane valve 1B is in the second backwash working position, although the seventh channel 107B is connected to the first channel 101B and the second jet channel 1012B respectively, since the seventh channel 107B is a conducting blind hole, and the second channel 102B and the first jet channel 1011B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, the raw water can only flow into the sixth channel 106B from the second fluid opening 1106B of the plane valve 1B, and further The wastewater flows through the fourth channel 104B and the fourth opening 1104B to the second water outlet 522 of the second water treatment device 52 and into the second water treatment device 52, and the wastewater generated by backwashing the second water treatment device 52 flows from the second water inlet 521 of the second water treatment device 52 to the third opening 1103B of the plane valve 1B, and is further discharged through the third channel 103B, the eighth channel 108B, the ninth channel 109B and the sewage opening 1109B of the plane valve 1B under the action of water pressure. In other words, although the seventh channel 107B of the planar valve 1B is respectively connected to the first channel 101B and the second jet channel 1012B, since the seventh channel 107B is a conductive blind hole, and the second channel 102B and the first jet channel 1011B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, the water does not flow through the flow channel formed by them. Correspondingly, when the plane valve 1B is in the second backwash working position, the second channel 102B of the plane valve 1B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the second opening 1102B of the plane valve 1B, so that the flow of water from the second opening 1102B to the first water outlet 512 of the first water treatment device 51 is blocked; and because the water does not flow through the flow channel formed by the seventh channel 107B being respectively connected to the first channel 101B and the second jet channel 1012B, no water flows in the first opening 1101B, thereby preventing the flow of water in the first water treatment device 51. In other words, although the seventh channel 107B is respectively connected to the first channel 101B and the second jet channel 1012B, the flow of water in the first water treatment device 51 is blocked because the movable valve plate 122B hinders the raw water from flowing to the second channel 102B, thereby ensuring that only the second water treatment device 52 is reverse flushed.

[0252] It is noteworthy that when the flat valve 1B is in the second backwash working position, the second channel 102B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the second opening 1102B. Although the seventh channel 107B is connected to the first channel 101B and the second jet channel 1012B, respectively, water does not flow through the flow channel formed by them, resulting in no water flowing in the first opening 1101B, isolating the first water treatment device 51 from the water flow, ensuring that only the second water treatment device 52 is backwashed. This increases the intensity of the raw water backwashing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51. Therefore, when the flat valve 1B is in the second backwash working position, the second water treatment device 52 of the water treatment machine of the present invention is backwashed separately.

[0253] As shown in the attached figure Figure 32 and Figure 37C As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the second backwash working position, the raw water from the plane valve 1B flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, and then flows from the second central pipe 524 to the second water treatment material 525 and backwashes the second water treatment material 525 under the action of water pressure. The generated sewage flows out from the second water inlet 521 of the second water treatment device 52, and under the action of water pressure, flows to the third opening 1103B of the first valve body 11B of the plane valve 1B, and then flows to the sewage opening 1109B through the fourth backwash flow channel 7104B and is discharged.

[0254] As shown in the attached figure Figure 29G 、 Figure 29H 、 Figure 33A 、 Figure 33B and Figure 37DAs shown, the flat valve 1B of the water treatment machine according to the second embodiment of the present invention further has a regeneration working position. When the flat valve 1B is in the regeneration working position, the sixth channel 106B is connected to the first jet channel 1011B, thereby forming the first regeneration flow channel 7301B connected to the second fluid opening 1106B and the first jet opening 11011B respectively. The seventh channel 107B is connected to the second jet channel 1012B and the fourth channel 104B respectively, thereby forming the second regeneration flow channel 7302B connected to the second jet opening 11012B and the fourth opening 1104B respectively. The eighth channel 108B is connected to the ninth channel 109B and the third channel 103B respectively, thereby forming the third regeneration flow channel 7303B connected to the sewage opening 1109B and the third opening 1103B respectively. As shown in the accompanying drawings 26A to 26I 、 Figure 29G 、 Figure 29H and Figure 37D As shown, when the planar valve 1B is in the regeneration working position, the first channel 101B and the second channel 102B of the planar valve 1B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fifth channel 105B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. Therefore, when the plane valve 1B of the water treatment machine of the present invention is in the regeneration working position, the raw water flows into the second fluid opening 1106B of the valve body 10B of the plane valve 1B under the action of water pressure, flows through the first regeneration flow channel 7301B (the sixth channel 106B and the first jet channel 1011B) to the first jet opening 11011B of the first valve body 11B, and then flows into the ejection port 182B of the ejector 18B. After the ejection of the ejector 18B, the salt solution (such as sodium chloride solution) from the salt intake port 181B is mixed to form a regeneration solution. The regeneration solution flows into the second jet opening 1106B of the first valve body 11B through the ejection port 183B of the ejector 18B. The regeneration solution flows from the second outlet 522 into the second water treatment device 52, and then flows through the second regeneration channel 7302B (the second jet channel 1012B, the seventh channel 107B and the fourth channel 104B) to the fourth opening 1104B of the first valve body 11B. The regeneration solution flows from the second outlet 522 into the second water treatment device 52, countercurrently regenerating the second water treatment material 525. After softening the resin, the wastewater generated after regeneration flows out from the second water inlet 521, and then flows out through the third opening 1103B of the first valve body 11B, the third regeneration channel 7303B (the third channel 103B, the eighth channel 108B and the ninth channel 109B) and the sewage outlet 1109B in sequence. As shown in the accompanying drawings, 26A to 26I 、 Figure 29G 、 Figure 29H and Figure 37DAs shown, specifically, when the plane valve 1B is in the regeneration working position, the first channel 101B and the second channel 102B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that the raw water can only flow into the sixth channel 106B from the second fluid opening 1106B of the plane valve 1B, and further in sequence through the first jet channel 1011B, the first jet opening 11011B, the ejector 18B, the second jet opening 11012B, the second jet channel 1012B, the seventh channel 107 ... The four channels 104B and the fourth opening 1104B flow toward the second water outlet 522 of the second water treatment device 52 and flow into the second water treatment device 52, countercurrently regenerating the softening material (for example, softening resin) of the second water treatment device 52. The generated wastewater flows from the second water inlet 521 of the second water treatment device 52 to the third opening 1103B of the plane valve 1B, and is further discharged through the third channel 103B, the eighth channel 108B, the ninth channel 109B and the sewage opening 1109B of the plane valve 1B under the action of water pressure. Correspondingly, when the plane valve 1B is in the regeneration working position, the first channel 101B and the second channel 102B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the first opening 1101B and the second opening 1102B of the plane valve 1B, so that the flow of water from the first opening 1101B to the first water inlet 511 of the first water treatment device 51 is blocked, the flow of water from the second opening 1102B to the first water outlet 512 of the first water treatment device 51 is blocked, and the flow of water in the first water treatment device 51 is blocked, thereby ensuring that only the second water treatment device 52 is regenerated in reverse flow.

[0255] It is worth noting that when the planar valve 1B is in the regeneration working position, the first channel 101B and the second channel 102B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that the first opening 1101B and the second opening 1102B are both blocked by the movable valve plate 122B, so that the first water treatment device 51 is isolated from the water flow to ensure that only the second water treatment device 52 is regenerated in the reverse flow, thereby increasing the intensity of the water flow of the regeneration solution for the reverse flow regeneration of the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. In particular, it is necessary to prevent the regeneration salt solution (or the sewage wastewater after the regeneration resin, because the sewage wastewater has a high salt content) from entering the first water treatment device 51. Because in actual use, the first water treatment device 51 is often other adsorbent filter materials such as activated carbon, the regeneration salt solution will contaminate the activated carbon and other filter materials, thereby weakening the purification capacity of the first water treatment device 51. This is also a major reason why multi-stage purification and softening water treatment equipment cannot simply use the activated carbon water treatment device and the softening resin water treatment device directly in series. Therefore, when the flat valve 1B is in the regeneration working position, the second water treatment device 52 of the water treatment machine of the present invention is regenerated separately in countercurrent.

[0256] As shown in the attached figure Figure 33A 、 Figure 33B and Figure 37D As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the regeneration working position, the raw water from the plane valve 1B is mixed with the salt solution from the ejector 18B under the action of water pressure to form a regeneration solution, which flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52, and then, under the action of water pressure, the second water treatment material 525 is regenerated in countercurrent, and the generated sewage flows out from the second water inlet 521 of the second water treatment device 52, and under the action of water pressure, flows to the third opening 1103B of the plane valve 1B, and then flows to the sewage opening 1109B through the third regeneration flow channel 7303B and is discharged.

[0257] As shown in the attached figure Figure 29I 、 Figure 29J 、 Figure 34 and Figure 37EAs shown, the plane valve 1B of the water treatment machine according to the second embodiment of the present invention further has a first positive flushing working position. When the plane valve 1B of the water treatment machine of the present invention is in the first positive flushing working position, the sixth channel 106B of the plane valve 1B is connected to the first channel 101B, thereby forming the first positive flushing flow channel 7201B connected to the second fluid opening 1106B and the first opening 1101B respectively, and the eighth channel 108B is connected to the ninth channel 109B and the second channel 102B respectively, thereby forming the second positive flushing flow channel 7202B connected to the sewage opening 1109B and the second opening 1102B respectively. As shown in the accompanying drawings 26A to 26I 、 Figure 29I 、 Figure 29J and Figure 37E As shown, when the plane valve 1B of the water treatment machine of the present invention is in the first positive flushing working position, the seventh channel 107B is connected to the second channel 102B and the fourth channel 104B respectively, the third channel 103B, the first jet channel 1011B and the second jet channel 1012B of the plane valve 1B are blocked by the second fluid control surface 1220B of the movable valve plate 122B respectively, and the fifth channel 105B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. 26A to 26I 、 Figure 29I 、 Figure 29J and Figure 37EAs shown, when the plane valve 1B is in the first positive flushing working position, although the seventh channel 107B of the plane valve 1B is connected to the second channel 102B and the fourth channel 104B respectively, since the seventh channel 107B is a conducting blind hole, and the third channel 103B, the first jet channel 1011B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, the raw water can only flow into the sixth channel 103B from the second fluid opening 1106B of the plane valve 1B. 6B, and further flows through the first channel 101B and the first opening 1101B to the first water inlet 511 of the first water treatment device 51 and into the first water treatment device 51. The wastewater generated by forward flushing the first water treatment device 51 flows from the first water outlet 512 of the first water treatment device 51 to the second opening 1102B of the plane valve 1B, and is further discharged through the second channel 102B, the eighth channel 108B, the ninth channel 109B, and the sewage outlet 1109B of the plane valve 1B under the action of water pressure. In other words, although the seventh channel 107B of the plane valve 1B is connected to the second channel 102B and the fourth channel 104B respectively, because the seventh channel 107B is a conductive blind hole and the third channel 103B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, water does not flow through the flow channel formed by them. Correspondingly, when the plane valve 1B is in the first positive flushing working position, the third channel 103B of the plane valve 1B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the third opening 1103B of the plane valve 1B, so that the flow of water from the second water inlet 521 of the second water treatment device 52 to the third opening 1103B is blocked, and the flow of water from the fourth opening 1104B to the second water outlet 522 of the second water treatment device 52 is blocked, so that no water flows in the fourth opening 1104B, and therefore, the flow of water in the second water treatment device 52 is blocked. In other words, although the seventh channel 107B is connected to the second channel 102B and the fourth channel 104B respectively, the flow of water in the second water treatment device 52 is blocked because the movable valve plate 122B blocks the flow of water to the third channel 103B, thereby ensuring that only the first water treatment device 51 is reverse flushed.

[0258] It is noteworthy that when the flat valve 1B is in the first positive flushing position, the third channel 103B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the third opening 1103B. This results in no water flowing through the fourth opening 1104B and no water flowing through the second water treatment device 52, ensuring that only the first water treatment device 51 is positively flushed. This increases the intensity of the raw water flow positively flushing the first water treatment device 51 while preventing the generated sewage from flowing into the second water treatment device 52. Therefore, when the flat valve 1B is in the first positive flushing position, the first water treatment device 51 of the water treatment machine of the present invention is positively flushed alone.

[0259] As shown in the attached figure Figure 34 and Figure 37E As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the first positive flushing working position, the raw water from the plane valve 1B flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then positively flushes the first water treatment material 515 under the action of water pressure. The generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, and flows to the second opening 1102B of the plane valve 1B under the action of water pressure, and then flows to the sewage opening 1109B through the second positive flushing channel 7202B and is discharged.

[0260] As shown in the attached figure Figure 29K 、 Figure 29L 、 Figure 35 and Figure 37F As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the present invention further has a second positive flushing working position. When the plane valve 1B of the water treatment machine of the present invention is in the second positive flushing working position, the sixth channel 106B of the plane valve 1B is connected to the third channel 103B, thereby forming the third positive flushing flow channel 7203B connected to the second fluid opening 1106B and the third opening 1103B respectively, and the eighth channel 108B is connected to the ninth channel 109B and the fourth channel 104B respectively, thereby forming the fourth positive flushing flow channel 7204B connected to the sewage opening 1109B and the fourth opening 1104B respectively. As shown in the accompanying drawings Figures 26A to 26I 、 Figure 29K 、 Figure 29L and Figure 37FAs shown, when the plane valve 1B of the water treatment machine of the present invention is in the second positive flushing working position, the seventh channel 107B of the plane valve 1B is connected to the first channel 101B and the first jet channel 1011B respectively, the second channel 102B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B respectively, and the fifth channel 105B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. Figures 26A to 26I 、 Figure 29K 、 Figure 29L and Figure 37FSpecifically, when the planar valve 1B is in the second positive flushing position, although the seventh channel 107B of the planar valve 1B is connected to the first channel 101B and the first jet channel 1011B respectively, since the seventh channel 107B is a conducting blind hole and the second channel 102B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, the raw water can only flow into the sixth channel 106B from the second fluid opening 1106B of the planar valve 1B. The wastewater further flows through the third channel 103B and the third opening 1103B to the second water inlet 521 of the second water treatment device 52 and into the second water treatment device 52. The wastewater generated by forward flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104B of the plane valve 1B, and is further discharged through the fourth channel 104B, the eighth channel 108B, the ninth channel 109B, and the sewage opening 1109B of the plane valve 1B under the action of water pressure. In other words, although the seventh channel 107B is connected to the first channel 101B and the first jet channel 1011B respectively, because the seventh channel 107B is a conductive blind hole and the second channel 102B and the second jet channel 1012B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, the water does not flow through the flow channel formed by them. Correspondingly, when the plane valve 1B is in the second positive flushing working position, the second channel 102B of the plane valve 1B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the second opening 1102B of the plane valve 1B, so that the flow of water from the second opening 1102B to the first water outlet 512 of the first water treatment device 51 is blocked; and because the water does not flow through the flow channel formed by the seventh channel 107B being respectively connected to the first channel 101B and the first jet channel 1011B, no water flows in the first opening 1101B, thereby preventing the flow of water in the first water treatment device 51. In other words, the seventh channel 107 is respectively connected to the first channel 101B and the first jet channel 1011B, but because the movable valve plate 122 blocks the raw water from flowing to the second channel 102B, the flow of water in the first water treatment device 51 is blocked, thereby ensuring that only the second water treatment device 52 is flushed in the forward direction.

[0261] It is noteworthy that when the flat valve 1B is in the second positive flushing position, the second channel 102B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the second opening 1102B. Although the seventh channel 107B is respectively connected to the first channel 101B and the first jet channel 1011B, water does not flow through the flow channel formed by them, resulting in no water flowing in the first opening 1101B, isolating the first water treatment device 51 from the water flow, ensuring that only the second water treatment device 52 is positively flushed. This increases the intensity of the raw water flow for positively flushing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51. Therefore, when the flat valve 1B is in the second positive flushing position, the second water treatment device 52 of the water treatment machine of the present invention is positively flushed alone.

[0262] As shown in the attached figure Figure 35 and Figure 37F As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the present utility model is controlled to be in the second positive flushing working position, the raw water from the plane valve 1B flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then positively flushes the second water treatment material 525 under the action of water pressure. The generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and flows to the fourth opening 1104B of the plane valve 1B under the action of water pressure, and then flows to the sewage opening 1109B through the fourth positive flushing channel 7204B and is discharged.

[0263] As shown in the attached figure Figure 29M 、 Figure 29N 、 Figure 36 and Figure 37G As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the present invention further has a water replenishment working position. When the plane valve 1B is in the water replenishment working position, the sixth channel 106B is connected to the second jet channel 1012B, thereby forming the water replenishment flow channel 7401B connected to the second fluid opening 1106B and the second jet opening 11012B respectively. Figures 26A to 26I 、 Figure 29M 、 Figure 29N and Figure 37GAs shown, when the plane valve 1B is in the water replenishment working position, the seventh channel 107B of the plane valve 1B is connected to the third channel 103B, one end of the eighth channel 108B is connected to the first jet channel 1011B, and the other end of the eighth channel 108B is blocked by the fourth fluid control surface 1230B of the second fixed valve plate 123B, the first channel 101B, the second channel 102B and the fourth channel 104B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fifth channel 105B is blocked by the third fluid control surface 1...
