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 (for example, 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, many water sources, whether surface water sources or groundwater sources, do not meet the standards for industrial water in terms of cleanliness and hardness. 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 is treated in multiple stages (two or more stages) 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 coarsely filter, filter and soften raw water in turn.

[0003] In addition, with the improvement of people's living standards and the increasing attention to health, people have higher and higher requirements for the quality of domestic water. However, the treatment of water taken back from the water source by the water plant is relatively extensive, which is not enough to remove all impurities, such as particulate pollutants (flocculent gel, silt, and even bacteria, etc.), which are increasingly difficult to meet people's needs. In addition, the aging of the tap water supply network will also bring new pollution to the tap water. Therefore, in order to further purify the tap water and improve its cleanliness, people also need a variety of water treatment methods to treat the tap water.

[0004] However, many existing water treatment systems or water treatment equipment for multi-stage treatment of raw water include multiple water treatment devices and multiple control valves that control the flow of water inside the corresponding water treatment devices, and 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 CN201810536738.8 discloses a water treatment system, which includes two water treatment devices and a plane valve for controlling the water treatment device to treat water, and can control the two water treatment devices to purify and soften water in series. However, the plane valve 10 of the water treatment system provided by the patent has a low utilization rate of the flow control surface of its fixed valve plate 12. In particular, when the water treatment system provided by the patent is in the first working state (purification-softening state), the first channel 101, the second channel 102, the third channel 103 and the fourth channel 104 (formed in the opening of the flow control surface of the fixed valve plate) distributed on the fixed valve plate 12 of the plane valve 10, especially the area of ​​the first channel 101 of the fixed valve plate 12 and the third channel 103 of the fixed valve plate 12 affect the water flow rate of the outlet water, but the total area of ​​the flow control surface of the fixed valve plate is too low, which greatly affects the water flow rate of the water treatment machine when purifying and softening the raw water. In order to make the water flow rate through the multifunctional purification-softening valve meet the requirements, the volume of the multifunctional purification-softening valve has to be increased, resulting in a larger size and inconvenience in use. The larger volume requires a thicker valve body wall thickness to ensure the stability of the valve body under water pressure, which directly leads to an increase in production costs. In addition, whether the movable valve plate of the multifunctional purification-softening valve is made of metal material or ceramic material, when its size is too large, it will lead to a decrease in the yield rate when it is manufactured. In particular, when the movable valve plate of the multifunctional purification-softening valve is made of ceramic material, the larger its size, the easier it is to crack, and the service life is significantly reduced. Finally, the control valve of the water treatment machine disclosed in the 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 third channel 103 of the fixed valve plate 12, and flows downward into the fifth channel 105 of the fixed valve plate 12 after being diverted by the tenth channel 1010 (diversion blind hole) of the movable valve plate 13, and then flows out from the second opening 1102 for water supply. It can be understood that when the water flows in the diversion blind hole (the tenth channel 1010 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 of the utility model is controlled to be in the water replenishment working position, the flow of water in the first opening 1101, the second opening 1102 and the third opening 1103 is prevented, so that the flow of water in the first water treatment device 51 and the second water treatment device 52 is prevented. 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 second opening 1102 or the third opening 1103 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.

[0183] As shown in the attached picture Figures 5 to 8CAs shown, the plane valve 1 of the water treatment machine according to the first embodiment of the 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 first jet channel 1011 and a second jet channel 1012, wherein the first channel 101, the second channel 102, the third channel 103, the first jet channel 1011 and the second jet channel 1012 are respectively arranged on the first fixed valve plate 121 and extend from the first fluid control surface 1210 of the first fixed valve plate 121; the fifth channel 105, the sixth channel 106 and the seventh channel 107 are respectively arranged on the movable valve plate 122, wherein the fifth channel 105 and the sixth channel 106 extend from the second fluid control surface 1210 of the movable valve plate 122 1220 extends, the seventh channel 107 extends from the second fluid control surface 1220 of the movable valve plate 122 to the third fluid control surface 1223; the fourth channel 104 and the eighth channel 108 are respectively arranged 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, the third channel 103 is connected to the third opening 1103, the fourth channel 104 is connected to the first fluid opening 1104, the fifth channel 105 is connected to the second fluid opening 1105, the eighth channel 108 is connected to the sewage opening 1108, 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 sixth channel 106 is a conducting blind hole. Preferably, the seventh channel 107 is a conducting through hole. Preferably, the fifth channel 105 is connected to the valve cavity 110 and further connected to the second fluid opening 1105 through the valve cavity 110 .

[0184] As shown in the attached picture Fig. 10A , Fig. 10B , Fig.11 and Fig.18AAs shown, according to the first embodiment of the utility model, the movable valve plate 122 of the plane valve 1 of the water treatment machine can rotate relative to the first fixed valve plate 121 and the second fixed valve plate 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 utility model is in the water treatment working position, the fifth channel 105 of the plane valve 1 is connected with the first channel 101, thereby forming the first water treatment flow channel 7001 respectively connected with the second fluid opening 1105 and the first opening 1101, and the seventh channel 107 is respectively connected with the third channel 103 and the fourth channel 104, thereby forming the second water treatment flow channel 7002 respectively connected with the third opening 1103 and the first fluid opening 1104. In other words, when the plane valve 1 of the water treatment machine of the utility model is in the water treatment working position, the water flow, under the action of water pressure, sequentially flows through the second fluid opening 1105 of the plane valve 1, the fifth channel 105, 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 water inlet 521 of the second water treatment device 52, the second water outlet 522 of the second water treatment device 52, the third opening 1103 of the plane valve 1, the third channel 103, the seventh channel 107, the fourth channel 104 and the first fluid opening 1104. As shown in the accompanying drawings 7A to 7I , Fig. 10A , Fig. 10B and Fig.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 sixth channel 106 is connected with the second channel 102, 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 eighth channel 108 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Although the sixth channel 106 of the plane valve 1 is connected with the second channel 102, since the sixth channel 106 is a conducting blind hole, the water flow does not flow through the flow channel formed by them. In other words, although the sixth channel 106 of the plane valve 1 is connected with the second channel 102, since the sixth channel 106 is a conducting blind hole, the second channel 102 is blocked by the movable valve plate 122.

[0185] It is worth noting that when the planar valve 1 of the water treatment machine of the utility model is in the water treatment working position, the second opening 1102 is respectively connected to 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, and the second channel 102 (or the flow channel formed by the sixth channel 106 being connected to the second channel 102) is blocked by the movable valve plate 122. That is to say, when the plane valve 1 of the water treatment machine of the utility model is in the water treatment working position, no water flows out or flows in through the second opening 1102. 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, and 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 process the raw water entering the second fluid opening 1105 of the plane valve 1, and the treated water flows out and is provided from the first fluid opening 1104. 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.

[0186] As shown in the attached picture Fig.11 and Fig.18AAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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 1105 of the valve body 10 under the action of water pressure, and then flows into the first opening 1101 through the fifth channel 105 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, 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 automatically The water flows out from the first water outlet 512 of the first water treatment device 51, further flows 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 third opening 1103, the third channel 103, the seventh channel 107, the fourth channel 104 and the first fluid opening 1104 of the planar valve 1 under the action of water pressure.

[0187] As shown in the attached picture Fig. 10C , Fig. 10D , Fig.12 and Fig.18B As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a first backwashing working position. When the plane valve 1 of the water treatment machine of the utility model is in the first backwashing working position, the fifth channel 105 of the plane valve 1 is connected with the second channel 102, thereby forming the first backwashing flow channel 7101 connected with the second fluid opening 1105 and the second opening 1102 respectively, and the seventh channel 107 is connected with the eighth channel 108 and the first channel 101 respectively, thereby forming the second backwashing flow channel 7102 connected with the sewage opening 1108 and the first opening 1101 respectively. As shown in the accompanying drawings 7A to 7I , Fig. 10C , Fig. 10D and Fig.18BAs shown, when the plane valve 1 of the water treatment machine of the utility model is in the first backwashing working position, the sixth channel 106 of the plane valve 1 is connected with the third channel 103, 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, and the fourth channel 104 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 backwashing working position, although the sixth channel 106 of the plane valve 1 is connected with the third channel 103, the sixth channel 106 is a conducting blind hole, and 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, so that the raw water can only flow into the fifth channel 105 from the second fluid opening 1105 of the plane valve 1, and further through the second channel 1 02, the second opening 1102 flows to the first water outlet 512 of the first water treatment device 51 and flows into the first water treatment device 51, and the waste water generated by reverse flushing 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 seventh channel 107, the eighth channel 108 and the sewage opening 1108 of the plane valve 1 under the action of water pressure. In other words, although the sixth channel 106 is connected to the third channel 103, the sixth channel 106 is a conducting blind hole, so the water does not flow through the flow channel formed by them, so the third channel 103 is blocked by the movable valve plate 122. Accordingly, when the plane valve 1 is in the first backwashing working position, the third channel 103 of the plane valve 1 is blocked by the movable valve plate 122, thereby preventing water from flowing through the third opening 1103 of the plane valve 1, so that the flow of water from the second opening 1102 to the second water inlet 521 of the second water treatment device 52 is prevented, and thus the flow of water in the second water treatment device 52 is prevented. In other words, although the sixth channel 106 is connected to the third channel 103, the movable valve plate 122 blocks the flow of water to the third channel 103, so that the flow of water in the second water treatment device 52 is prevented, thereby ensuring that only the first water treatment device 51 is backwashed.

[0188] It is worth noting that when the plane valve 1 is in the first backwashing working position, the third channel 103 (or the flow channel formed by the sixth channel 106 and the third channel 103) is blocked by the movable valve plate 122, so that no water flows in the third opening 1103, and no water flows in the second water treatment device 52, so as to ensure that only the first water treatment device 51 is backwashed, thereby increasing the intensity of the water flow of the raw water backwashing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52. Therefore, when the plane valve 1 is in the first backwashing working position, the first water treatment device 51 of the water treatment machine of the utility model is backwashed separately.

[0189] As shown in the attached picture Fig.12 and Fig.18B As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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, and 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 1108 through the second backwash channel 7102 and is discharged.

[0190] As shown in the attached picture Fig. 10E , Fig.10F , Fig.13 and Fig.18C As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a second backwashing working position. When the plane valve 1 of the water treatment machine of the utility model is in the second backwashing working position, the fifth channel 105 of the plane valve 1 is connected with the third channel 103, thereby forming the third backwashing flow channel 7103 connected with the second fluid opening 1105 and the third opening 1103 respectively, and the seventh channel 107 is connected with the eighth channel 108 and the second channel 102 respectively, thereby forming the fourth backwashing flow channel 7104 connected with the sewage opening 1108 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I , Fig. 10E , Fig.10F and Fig.18CAs shown, when the plane valve 1 of the water treatment machine of the utility model is in the second backwashing working position, the sixth channel 106 of the plane valve 1 is connected to the third channel 103, 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, and the fourth channel 104 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I , Fig. 10E , Fig.10F and Fig.18C Specifically, when the plane valve 1 is in the second backwashing working position, although the sixth channel 106 is connected to the third channel 103, since the sixth channel 106 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, the raw water can only flow into the fifth channel 105 from the second fluid opening 1105 of the plane valve 1, and further through the The third channel 103 and the third opening 1103 flow toward the second water outlet 522 of the second water treatment device 52 and flow into the second water treatment device 52. The waste water 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 second opening 1102 of the plane valve 1, and is further discharged through the second channel 102, the seventh channel 107, the eighth channel 108 and the sewage opening 1108 of the plane valve 1 under the action of water pressure. In other words, although the sixth channel 106 of the plane valve 1 is connected to the third channel 103, the sixth channel 106 is a conducting blind hole, so the water does not flow through the flow channel formed by them. Therefore, when the plane valve 1 is in the second backwashing working position, the first channel 101 of the plane valve 1 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 of the plane valve 1, so that the flow of water from the second water inlet 521 of the second water treatment device 52 to the first water outlet 512 of the first water treatment device 51 is prevented, and thus the flow of water in the first water treatment device 51 is prevented. In other words, although the sixth channel 106 is connected to the third channel 103, the flow of water in the first water treatment device 51 is prevented because the movable valve plate 122 blocks the flow of water to the first channel 101, thereby ensuring that only the second water treatment device 52 is backwashed.

[0191] It is worth noting that when the plane valve 1 is in the second backwashing working position, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that no water flows in the first opening 1101, and no water flows in the first water treatment device 51, so as to ensure that only the second water treatment device 52 is backwashed, thereby increasing the intensity of the water flow of the raw water backwashing the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. Therefore, when the plane valve 1 is in the second backwashing working position, the second water treatment device 52 of the water treatment machine of the utility model is backwashed separately.

[0192] As shown in the attached picture Fig.13 and Fig.18C As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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 center pipe 524 to the second water treatment material 525 and backwashes the second water treatment material 525 under the action of water pressure, 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 second opening 1102 of the first valve body part 11 of the plane valve 1, and then flows to the sewage opening 1108 through the fourth backwash channel 7104 and is discharged.

[0193] As shown in the attached picture Figure 10G , Fig. 10H , Fig.14A , Fig. 14B and Fig.18D As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a regeneration working position. When the plane valve 1 is in the regeneration working position, the fifth channel 105 of the plane valve 1 is connected with the first jet channel 1011, thereby forming the first regeneration flow channel 7301 respectively connected with the second fluid opening 1105 and the first jet opening 11011, the sixth channel 106 is respectively connected with the second jet channel 1012 and the second channel 102, thereby forming the second regeneration flow channel 7302 respectively connected with the second jet opening 11012 and the second opening 1102, and the seventh channel 107 is respectively connected with the eighth channel 108 and the third channel 103, thereby forming the third regeneration flow channel 7303 respectively connected with the sewage opening 1108 and the third opening 1103. As shown in the accompanying drawings 7A to 7I , Figure 10G , Fig. 10H and Fig.18DAs shown, when the planar valve 1 is in the regeneration working position, the first channel 101 of the planar valve 1 is blocked by the second fluid control surface 1220 of the movable valve plate 122 , and the fourth channel 104 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 utility model is in the regeneration working position, the raw water flows in from the second fluid opening 1105 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 fifth channel 105 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, passes through the ejection of the ejector 18, mixes with the salt solution (such as sodium chloride solution) from the salt absorption port 181 to form a regeneration solution, and the regeneration solution flows into the second jet opening 1103 of the ejector 18 into the first valve body 11. The regeneration solution flows into the second water treatment device 52 from the second water inlet 521, and then flows into the second opening 1102 of the first valve body 11 through the second regeneration flow channel 7302 (the second jet channel 1012, the sixth channel 106 and the second channel 102). The regeneration solution flows into the second water treatment device 52 from the second water inlet 521, and regenerates the second water treatment material 525 downstream. After the resin is softened, the waste water generated after regeneration flows out from the second water outlet 522, and then flows out through the third opening 1103 of the first valve body 11, the third regeneration flow channel 7303 (the third channel 103, the seventh channel 107 and the eighth channel 108) and the sewage discharge opening 1108 in sequence. As shown in the accompanying drawings 7A to 7I , Figure 10G , Fig. 10H and Fig.18DAs shown, specifically, when the plane valve 1 is in the regeneration working position, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the fifth channel 105 from the second fluid opening 1105 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 sixth channel 106, the second channel 102 and the The second opening 1102 flows toward the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52, regenerating the softening material (for example, softening resin) of the second water treatment device 52 downstream, and the generated wastewater flows from the second water outlet 522 of the second water treatment device 52 toward the third opening 1103 of the plane valve 1, and is further discharged through the third channel 103, the seventh channel 107, the eighth channel 108 and the sewage opening 1108 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 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 of the planar valve 1, so that 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.

[0194] It is worth noting that when the plane valve 1 is in the regeneration working position, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that no water flows in the first opening 1101, and no water flows in the first water treatment device 51, so as 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 to regenerate the second water treatment device 52 downstream, 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 higher 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, and the regeneration salt solution will contaminate the filter materials such as activated carbon, thereby weakening the purification capacity of the first water treatment device 51, which is also a major reason why the 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 plane valve 1 is in the regeneration working position, the second water treatment device 52 of the water treatment machine of the utility model is regenerated downstream alone.

[0195] As shown in the attached picture Fig.14A , Fig. 14B and Fig.18DAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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 under the action of water pressure, the second water treatment material 525 is regenerated downstream, and 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 third opening 1103 of the plane valve 1, and then flows to the sewage opening 1108 through the third regeneration flow channel 7303 and is discharged.

[0196] As shown in the attached picture Fig.10I , Fig.10J , Fig.15 and Fig.18E As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a first positive flushing working position. When the plane valve 1 of the water treatment machine of the utility model is in the first positive flushing working position, the fifth channel 105 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 1105 and the first opening 1101 respectively, and the seventh channel 107 is connected with the eighth channel 108 and the second channel 102 respectively, thereby forming the second positive flushing flow channel 7202 connected with the sewage opening 1108 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I , Fig.10I , Fig.10J and Fig.18E As shown, when the plane valve 1 of the water treatment machine of the utility model is in the first positive flushing working position, the sixth channel 106 of the plane valve 1 is connected with the first channel 101, the third channel 103, 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, and the fourth channel 104 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I , Fig.10I , Fig.10J and Fig.18EAs shown, when the plane valve 1 is in the first positive flushing working position, although the sixth channel 106 of the plane valve 1 is connected to the first channel 101, the sixth channel 106 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 fifth channel 105 from the second fluid opening 1105 of the plane valve 1, and further through the The first channel 101 and the first opening 1101 flow toward the first water inlet 511 of the first water treatment device 51 and flow into the first water treatment device 51. The waste water generated by positively 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 plane valve 1, and is further discharged through the second channel 102, the seventh channel 107, the eighth channel 108 and the sewage opening 1108 of the plane valve 1 under the action of water pressure. In other words, although the sixth channel 106 of the plane valve 1 is connected to the first channel 101, since the sixth channel 106 is a conducting blind hole, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1 is in the first positive flushing 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 of the plane valve 1, so that the flow of water from the first water outlet 512 of the first water treatment device 51 to the second water inlet 521 of the second water treatment device 52 is prevented, thereby preventing the flow of water in the second water treatment device 52. In other words, although the sixth channel 106 is connected to the first channel 101, the movable valve plate 122 blocks the flow of water to the third channel 103, so that the flow of water in the second water treatment device 52 is prevented, thereby ensuring that only the first water treatment device 51 is positively flushed.

[0197] It is worth noting that when the plane valve 1 is in the first positive flushing working position, the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that no water flows in the third opening 1103, and no water flows in the second water treatment device 52, so as to ensure that only the first water treatment device 51 is positively flushed, thereby increasing the strength of the water flow of the raw water for positively flushing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52. Therefore, when the plane valve 1 is in the first positive flushing working position, the first water treatment device 51 of the water treatment machine of the utility model is positively flushed alone.

[0198] As shown in the attached picture Fig.15 and Fig.18EAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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, and 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 1108 through the second positive flushing channel 7202 and is discharged.

[0199] As shown in the attached picture Figure 10K , Fig.10L , Fig.16 and Fig.18F As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a second positive flushing working position. When the plane valve 1 of the water treatment machine of the utility model is in the second positive flushing working position, the fifth channel 105 of the plane valve 1 is connected with the second channel 102, thereby forming the third positive flushing flow channel 7203 connected with the second fluid opening 1105 and the second opening 1102 respectively, and the seventh channel 107 is connected with the eighth channel 108 and the third channel 103 respectively, thereby forming the fourth positive flushing flow channel 7204 connected with the sewage opening 1108 and the third opening 1103 respectively. As shown in the accompanying drawings 7A to 7I , Figure 10K , Fig.10L and Fig.18F As shown, when the plane valve 1 of the water treatment machine of the utility model is in the second positive flushing working position, the sixth channel 106 of the plane valve 1 is connected to the first jet channel 1011 and the second jet channel 1012 respectively, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the fourth channel 104 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 , Fig.10L and Fig.18FAs shown, specifically, when the plane valve 1 is in the second positive flushing working position, although the sixth channel 106 of the plane valve 1 is connected to the first jet channel 1011 and the second jet channel 1012 respectively, the sixth channel 106 is a conducting blind hole, and the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the fifth channel 105 from the second fluid opening 1105 of the plane valve 1, and further through the second jet channel 1012. The channel 102 and the second opening 1102 flow toward the second water inlet 521 of the second water treatment device 52 and flow into the second water treatment device 52. The waste water generated by positively flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the third opening 1103 of the plane valve 1, and is further discharged through the third channel 103, the seventh channel 107, the eighth channel 108 and the sewage opening 1108 of the plane valve 1 under the action of water pressure. In other words, although the sixth channel 106 is connected to the first jet channel 1011 and the second jet channel 1012 respectively, since the sixth channel 106 is a conducting blind hole, the water does not flow through the flow channel formed by them. Correspondingly, when the plane valve 1 is in the second positive flushing working position, the first channel 101 of the plane valve 1 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 of the plane valve 1, so that the flow of water from the second opening 1102 to the first water outlet 512 of the first water treatment device 51 is prevented, and thus the flow of water in the first water treatment device 51 is prevented. In other words, the sixth channel 106 is connected to the first jet channel 1011 and the second jet channel 1012 respectively, but because the movable valve plate 122 blocks the flow of water to the first channel 101, the flow of water in the first water treatment device 51 is prevented, thereby ensuring that only the second water treatment device 52 is positively flushed.

[0200] It is worth noting that when the plane valve 1 is in the second positive flushing working position, the first channel 101 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that no water flows in the first opening 1101, and no water flows in the first water treatment device 51, so as to ensure that only the second water treatment device 52 is positively flushed, thereby increasing the strength of the water flow of the raw water for positively flushing the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. Therefore, when the plane valve 1 is in the second positive flushing working position, the second water treatment device 52 of the water treatment machine of the utility model is positively flushed alone.

[0201] As shown in the attached picture Fig.16 and Fig.18FAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the 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, and 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 third opening 1103 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 1108 through the fourth positive flushing channel 7204 and is discharged.

[0202] As shown in the attached picture Figure 10M , Fig.10N , Fig.17 and Figure 18G As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the utility model further has a water replenishment working position. When the plane valve 1 is in the water replenishment working position, the fifth channel 105 of the plane valve 1 is connected with the second jet channel 1012, thereby forming the water replenishment channel 7401 connected with the second fluid opening 1105 and the second jet opening 11012 respectively. 7A to 7I , Figure 10M , Fig.10N and Figure 18GAs shown, when the planar valve 1 is in the water replenishing working position, the sixth channel 106 of the planar valve 1 is respectively connected with the second channel 102 and the third channel 103, the seventh channel 107 is respectively connected with the eighth channel 108 and the first channel 101, the first jet channel 1011 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the fourth channel 104 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 utility model is in the water replenishment working position, the raw water flows in from the second fluid opening 1105 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 fifth channel 105 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 sixth channel 106 is respectively connected to the second channel 102 and the third channel 103, and the seventh channel 107 is respectively connected to the eighth channel 108 and the first channel 101, the sixth channel 106 is a conductive blind hole and the seventh channel 107 is a conductive through hole, so that the eighth channel 108, the seventh channel 107, the first channel 101, the first opening 1101, the first water treatment device 51, the second water treatment device 52, the third opening 1103, the third channel 103, the sixth channel 106, the second channel 102, the second opening 1102 and the first water treatment device 51 (the second water treatment device 52) form a flow channel isolated from the raw water, so that the water flow cannot flow through the first opening 1101, the second opening 1102 and the third opening 1103. In other words, although the sixth channel 106 is connected to the second channel 102 and the third channel 103 respectively, and the seventh channel 107 is connected to the eighth channel 108 and the first channel 101 respectively, a flow channel allowing water to flow cannot be formed.

[0203] It is worth noting that the traditional plane valve adopts a valve core structure of a single moving valve plate and a single fixed valve plate. When in the water treatment working position, the moving valve plate often needs a conducting blind hole to guide the water flow to the water outlet. When the water flows in the 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, so that the flow rate of the water flow is significantly reduced. The plane valve 1 of the water treatment machine of the utility model adopts a three-valve plate structure. The water flow to the water outlet flows upward from the third channel 103 of the lower valve plate (the first fixed valve plate 121) and the seventh channel 107 of the moving valve plate 122. The outlet is in the eighth channel 108 of the upper valve plate (the second fixed valve plate 123). The change in the flow direction of the water flow is small (roughly), and the resistance encountered by the water flow in the process of changing the flow direction is also small, and the loss of the water flow rate is also significantly reduced. Furthermore, in the existing planar valve with a single fixed valve plate, the channel for controlling the flow direction of water provided on the fixed valve plate can only be provided on the single fixed valve plate, resulting in more through holes provided in the single fixed valve plate, and each through hole often occupies a relatively small space. In order to ensure the water flow rate, the diameter of the fixed valve plate of the planar valve is 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 moving valve plate 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 a thicker wall thickness. Since the diameter of the moving valve plate also needs to be increased accordingly, the thickness of the moving valve plate also needs to be increased accordingly, which 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 first jet channel 1011 and the second jet channel 1012 of the plane valve 1 of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121, and the fourth channel 104 and the eighth channel 108 are respectively arranged on the second fixed valve plate 123, thereby allowing the space occupied by each channel arranged on the first fixed valve plate 121 and the second fixed valve plate 123 to be larger and increasing the water flow rate, especially the first channel 101 and the third channel 103 which are the main channels of the water treatment working position occupy a relatively large space in the first fixed valve plate 121. In other words, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the eighth channel 108, the first jet channel 1011 and the second jet channel 1012 of the planar valve 1 of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121 and the second fixed valve plate 123, which can significantly reduce the diameter of the fixed and movable valve plates of the planar 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 planar valve and making the entire planar valve structure lighter and easier to operate.

As shown in the accompanying drawings FIG. 26A to FIG. 26I , Fig.29A , Fig.29B and Fig.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 sixth channel 106B is connected to the second channel 102B, the first jet channel 1011B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the eighth channel 108B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. Although the sixth channel 106B of the plane valve 1B is connected to the second channel 102B, since the sixth channel 106B is a conducting blind hole, the water flow does not flow through the flow channel formed by them. In other words, although the sixth channel 106B of the plane valve 1B is connected to the second channel 102B, since the sixth channel 106B is a conducting blind hole, the second channel 102B is blocked by the movable valve plate 122B.

[0243] It is worth noting that when the plane valve 1B of the water treatment machine of the utility model is in the water treatment working position, the second opening 1102B is respectively connected to 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, and the second channel 102B (or the flow channel formed by the sixth channel 106B and the second channel 102B) is blocked by the movable valve plate 122B. That is to say, when the plane valve 1B of the water treatment machine of the utility model is in the water treatment working position, no water flows out or flows in through the second opening 1102B. 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, and 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 process the raw water entering the second fluid opening 1105B of the plane valve 1B, and the treated water flows out and is provided from the first fluid opening 1104B. 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.

[0244] As shown in the attached picture Fig.30 and Fig.37AAs shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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 1105B of the valve body 10B under the action of water pressure, and then flows into the first opening 1101B through the fifth channel 105B 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, the raw water is treated by the first water treatment material 515 (for example, purified), and the generated primary treated water is collected by the first central pipe 514 and The secondary treated water flows out from the first water outlet 512 of the first water treatment device 51, further flows 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 third opening 1103B, the third channel 103B, the seventh channel 107B, the fourth channel 104B and the first fluid opening 1104B of the plane valve 1B under the action of water pressure.

[0245] As shown in the attached picture Fig.29C , Fig.29D , Fig.31 and Fig.37B As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a first backwashing working position. When the plane valve 1B of the water treatment machine of the utility model is in the first backwashing working position, the fifth channel 105B of the plane valve 1B is connected with the second channel 102B, thereby forming the first backwashing flow channel 7101B connected with the second fluid opening 1105B and the second opening 1102B respectively, and the seventh channel 107B is connected with the eighth channel 108B and the first channel 101B respectively, thereby forming the second backwashing flow channel 7102B connected with the sewage opening 1108B and the first opening 1101B respectively. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Fig.29C , Fig.29D and Fig.37BAs shown, when the plane valve 1B of the water treatment machine of the utility model is in the first backwash working position, the sixth channel 106B is respectively connected with the second channel 102B 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, and the fourth channel 104B 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 backwashing working position, although the sixth channel 106B of the plane valve 1B is connected to the second channel 102B and the third channel 103B respectively, the sixth channel 106B is a conducting blind hole, and the first jet channel 1011B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B respectively, so that the raw water can only flow into the fifth channel 105B from the second fluid opening 1105B of the plane valve 1B, and further The waste water 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 waste water generated by reverse flushing 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 seventh channel 107B, the eighth channel 108B and the sewage opening 1108B of the plane valve 1B under the action of water pressure. In other words, although the sixth channel 106B is connected to the second channel 102B and the third channel 103B respectively, the sixth channel 106B, the second channel 102B, the second opening 1102B, the second water inlet 521 of the second water treatment device 52, the second water treatment device 52, the second water outlet 522 of the second water treatment device 52, the third opening 1103B, the third channel 103B and the sixth channel 106B form a circulating connecting channel, so that the water pressure at the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is the same, so that there is no water flow in the second water treatment device 52, and therefore the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1B is in the first backwashing working position, the sixth channel 106B of the plane valve 1B is connected to the second channel 102B and the third channel 103B respectively, so that the water pressure at the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is the same, and therefore, no water flows in the second water treatment device 52. In other words, although the sixth channel 106B is connected to the second channel 102B and the third channel 103B respectively, the water does not flow through the flow channel formed by them, so that no water flows in the second water treatment device 52, thereby ensuring that only the first water treatment device 51 is backwashed.

[0246] It is worth noting that when the plane valve 1B is in the first backwashing working position, although the sixth channel 106B is connected to the second channel 102B and the third channel 103B respectively, so that the water pressure at the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is the same, so that no water flows in the second water treatment device 52, so as to ensure that only the first water treatment device 51 is backwashed, thereby increasing the intensity of the water flow of the raw water backwashing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52. Therefore, when the plane valve 1B is in the first backwashing working position, the first water treatment device 51 of the water treatment machine of the utility model is backwashed alone.

[0247] As shown in the attached picture Fig.31 and Fig.37B As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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, and 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 1108B through the second backwash channel 7102B and is discharged.

[0248] As shown in the attached picture Fig.29E , Fig.29F , Fig.32 and Fig.37C As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a second backwashing working position. When the plane valve 1B of the water treatment machine of the utility model is in the second backwashing working position, the fifth channel 105B of the plane valve 1B is connected with the third channel 103B, thereby forming the third backwashing flow channel 7103B connected with the second fluid opening 1105B and the third opening 1103B respectively, and the seventh channel 107B is connected with the eighth channel 108B and the second channel 102B respectively, thereby forming the fourth backwashing flow channel 7104B connected with the sewage opening 1108B and the second opening 1102B respectively. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Fig.29E , Fig.29F and Fig.37CAs shown, when the plane valve 1B of the water treatment machine of the utility model is in the second backwashing working position, the sixth channel 106B is connected to the first channel 101B, the first jet channel 1011B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fourth channel 104B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. FIG. 26A to FIG. 26I , Fig.29E , Fig.29F and Fig.37C Specifically, when the plane valve 1B is in the second backwashing working position, although the sixth channel 106B is connected to the first channel 101B, since the sixth channel 106B is a conducting blind hole, and 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 fifth channel 105B from the second fluid opening 1105B of the plane valve 1B, and further through the third channel 103B, the third opening 1103B flows to the second water outlet 522 of the second water treatment device 52 and flows into the second water treatment device 52, and the waste water 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 second opening 1102B of the plane valve 1B, and is further discharged through the second channel 102B, the seventh channel 107B, the eighth channel 108B and the sewage discharge opening 1108B of the plane valve 1B under the action of water pressure. In other words, although the sixth channel 106B of the plane valve 1B is connected to the first channel 101B, since the sixth channel 106B is a conducting blind hole, the water flow does not flow through the flow channel formed by them, so the first channel 101B is blocked by the movable valve plate 122B. Accordingly, when the plane valve 1B is in the second backwashing working position, the first channel 101B of the plane valve 1B is blocked by the movable valve plate 122B, thereby preventing water from flowing through the first opening 1101B 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 first water outlet 512 of the first water treatment device 51 is prevented, and thus the flow of water in the first water treatment device 51 is prevented. In other words, although the sixth channel 106B is connected to the first channel 101B, the flow of water in the first water treatment device 51 is prevented because the movable valve plate 122B hinders the flow of water to the first channel 101B, thereby ensuring that only the second water treatment device 52 is backwashed.

[0249] It is worth noting that when the plane valve 1B is in the second backwashing working position, the first channel 101B (or the flow channel formed by the sixth channel 106B and the first channel 101B) is blocked by the movable valve plate 122B, so that no water flows in the first opening 1101B, and no water flows in the first water treatment device 51, so as to ensure that only the second water treatment device 52 is backwashed, thereby increasing the intensity of the water flow of the raw water for backwashing the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. Therefore, when the plane valve 1B is in the second backwashing working position, the second water treatment device 52 of the water treatment machine of the utility model is backwashed separately.

[0250] As shown in the attached picture Fig.32 and Fig.37C As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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 center pipe 524 to the second water treatment material 525 and backwashes the second water treatment material 525 under the action of water pressure, 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 second opening 1102B of the first valve body 11B of the plane valve 1B, and then flows to the sewage opening 1108B through the fourth backwash channel 7104B and is discharged.

[0251] As shown in the attached picture Figure 29G , Fig.29H , Fig.33A , Fig.33B and Fig.37D As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a regeneration working position. When the plane valve 1B is in the regeneration working position, the fifth channel 105B is connected to the first jet channel 1011B, thereby forming the first regeneration flow channel 7301B connected to the second fluid opening 1105B and the first jet opening 11011B respectively, the sixth channel 106B is connected to the second jet channel 1012B and the third channel 103B respectively, thereby forming the second regeneration flow channel 7302B connected to the second jet opening 11012B and the third opening 1103B respectively, and the seventh channel 107B is connected to the eighth channel 108B and the second channel 102B respectively, thereby forming the third regeneration flow channel 7303B connected to the sewage opening 1108B and the second opening 1102B respectively. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Figure 29G , Fig.29H and Fig.37D As shown, when the planar valve 1B is in the regeneration working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fourth channel 104B 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 utility model is in the regeneration working position, the raw water flows in from the second fluid opening 1105B 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 fifth channel 105B 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, passes through the ejection port 18B, mixes with the salt solution (such as sodium chloride solution) from the salt absorption port 181B to form a regeneration solution, and the regeneration solution flows into the second jet opening 1105B of the first valve body 11B through the ejection port 183B of the ejector 18B. The regeneration solution flows into the second water treatment device 52 from the second water outlet 522, and regenerates the second water treatment material 525 in reverse flow, such as softening the resin. The waste water generated after regeneration flows out from the second water inlet 521, and then flows out through the second opening 1102B of the first valve body 11B, the third regeneration flow channel 7303B (the second channel 102B, the seventh channel 107B and the eighth channel 108B) and the sewage outlet 1108B in sequence. As shown in the attached figure FIG. 26A to FIG. 26I , Figure 29G , Fig.29H and Fig.37DAs shown, specifically, when the plane valve 1B is in the regeneration working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that the raw water can only flow into the fifth channel 105B from the second fluid opening 1105B of the plane valve 1B, and further sequentially 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 sixth channel 106B, the third channel 103 B and the third opening 1103B 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, and the generated wastewater flows from the second water inlet 521 of the second water treatment device 52 to the second opening 1102B of the plane valve 1B, and is further discharged through the second channel 102B, the seventh channel 107B, the eighth channel 108B and the sewage opening 1108B of the plane valve 1B under the action of water pressure. Correspondingly, when the planar valve 1B is in the regeneration working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the first opening 1101B 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 first water outlet 512 of the first water treatment device 51 is blocked, thereby ensuring that only the second water treatment device 52 is regenerated in reverse flow.

[0252] It is worth noting that when the plane valve 1B is in the regeneration working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that no water flows in the first opening 1101B and no water flows in the first water treatment device 51, so as to ensure that only the second water treatment device 52 is regenerated in reverse flow, thereby increasing the intensity of the water flow of the regeneration solution for reverse 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 higher 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, and the regeneration salt solution will contaminate the filter materials such as activated carbon, thereby weakening the purification capacity of the first water treatment device 51, which is also a major reason why the 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 plane valve 1B is in the regeneration working position, the second water treatment device 52 of the water treatment machine of the utility model is regenerated individually in the countercurrent manner.

[0253] As shown in the attached picture Fig.33A , Fig.33B and Fig.37D As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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 second opening 1102B of the plane valve 1B, and then flows to the sewage opening 1108B through the third regeneration flow channel 7303B and is discharged.

[0254] As shown in the attached picture Fig.29I , Fig.29J , Fig.34 and Fig.37E As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a first positive flushing working position. When the plane valve 1B of the water treatment machine of the utility model is in the first positive flushing working position, the fifth channel 105B of the plane valve 1B is connected with the first channel 101B, thereby forming the first positive flushing flow channel 7201B connected with the second fluid opening 1105B and the first opening 1101B respectively, and the seventh channel 107B is connected with the eighth channel 108B and the second channel 102B respectively, thereby forming the second positive flushing flow channel 7202B connected with the sewage opening 1108B and the second opening 1102B respectively. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Fig.29I , Fig.29J and Fig.37E As shown, when the plane valve 1B of the water treatment machine of the utility model is in the first positive flushing working position, the sixth channel 106B is connected to the second jet channel 1012B, the third channel 103B and the first jet channel 1011B are blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fourth channel 104B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. FIG. 26A to FIG. 26I , Fig.29I , Fig.29J and Fig.37EAs shown in FIG. 1 , when the plane valve 1B is in the first positive flushing working position, although the sixth channel 106B of the plane valve 1B is connected to the second jet channel 1012B, since the sixth channel 106B is a conducting blind hole, and the third channel 103B 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 fifth channel 105B from the second fluid opening 1105B of the plane valve 1B, and further flow into the fifth channel 105B through the first jet channel 1012B. The waste water generated by the channel 101B and the first opening 1101B flows to the first water inlet 511 of the first water treatment device 51 and flows into the first water treatment device 51, and the waste water generated by the forward flushing of 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 seventh channel 107B, the eighth channel 108B and the sewage discharge opening 1108B of the plane valve 1B under the action of water pressure. In other words, although the sixth channel 106B of the plane valve 1B is connected to the second jet channel 1012B, since the sixth channel 106B is a conducting blind hole, the water flow does not flow through the flow channel formed by them. Accordingly, when the plane valve 1B is in the first positive flushing working 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 of the plane valve 1B, so that the waste water generated by the positive flushing of the first water treatment device 51 is prevented from flowing from the first water outlet 512 of the first water treatment device 51 to the second water inlet 521 of the second water treatment device 52, thereby preventing the flow of water in the second water treatment device 52. In other words, although the sixth channel 106B is connected to the second jet channel 1012B, the movable valve plate 122B blocks the flow of water to the third channel 103B, so that the flow of water in the second water treatment device 52 is prevented, thereby ensuring that only the first water treatment device 51 is positively flushed.

[0255] It is worth noting that when the plane valve 1B is in the first positive flushing working position, the third channel 103B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that no water flows in the third opening 1103B, and no water flows in the second water treatment device 52, so as to ensure that only the first water treatment device 51 is positively flushed, thereby increasing the strength of the water flow of the raw water for positively flushing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52. Therefore, when the plane valve 1B is in the first positive flushing working position, the first water treatment device 51 of the water treatment machine of the utility model is positively flushed alone.

[0256] As shown in the attached picture Fig.34and Fig.37E As shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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, and 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 1108B through the second positive flushing channel 7202B and is discharged.

[0257] As shown in the attached picture Figure 29K , Figure 29L , Fig.35 and Fig.37F As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a second positive flushing working position. When the plane valve 1B of the water treatment machine of the utility model is in the second positive flushing working position, the fifth channel 105B of the plane valve 1B is connected with the second channel 102B, thereby forming the third positive flushing flow channel 7203B respectively connected with the second fluid opening 1105B and the second opening 1102B, and the seventh channel 107B is respectively connected with the eighth channel 108B and the third channel 103B, thereby forming the fourth positive flushing flow channel 7204B respectively connected with the sewage opening 1108B and the third opening 1103B. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Figure 29K , Figure 29L and Fig.37F As shown, when the plane valve 1B of the water treatment machine of the utility model is in the second positive flushing working position, the sixth channel 106B is connected to the second channel 102B, the first channel 101B, the first jet channel 1011B and the second jet channel 1012B are blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fourth channel 104B is blocked by the third fluid control surface 1223B of the movable valve plate 122B. As shown in the accompanying drawings FIG. 26A to FIG. 26I , Figure 29K , Figure 29L and Fig.37FAs shown, specifically, when the plane valve 1B is in the second positive flushing working position, although the sixth channel 106B of the plane valve 1B is connected to the second channel 102B, since the sixth channel 106B is a conducting blind hole, and the first channel 101B, 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 fifth channel 105B from the second fluid opening 1105B of the plane valve 1B, and The waste water further flows through the second channel 102B and the second opening 1102B to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52. The waste water generated by positively flushing the second water treatment device 52 flows from the second water outlet 522 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 seventh channel 107B, the eighth channel 108B and the sewage opening 1108B of the plane valve 1B under the action of water pressure. In other words, although the sixth channel 106B is connected to the second channel 102B, since the sixth channel 106B is a conducting blind hole, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1B is in the second positive flushing working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, thereby preventing water from flowing through the first opening 1101B 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 prevented, and thus the flow of water in the first water treatment device 51 is prevented. In other words, although the sixth channel 106 is connected to the second channel 102B, the flow of water in the first water treatment device 51 is prevented because the movable valve plate 122 blocks the flow of water to the first channel 101B, thereby ensuring that only the second water treatment device 52 is positively flushed.

[0258] It is worth noting that when the plane valve 1B is in the second positive flushing working position, the first channel 101B is blocked by the second fluid control surface 1220B of the movable valve plate 122B, so that no water flows in the first opening 1101B, and no water flows in the first water treatment device 51, so as to ensure that only the second water treatment device 52 is positively flushed, thereby increasing the strength of the water flow of the raw water for positively flushing the second water treatment device 52, and preventing the generated sewage from flowing to the first water treatment device 51. Therefore, when the plane valve 1B is in the second positive flushing working position, the second water treatment device 52 of the water treatment machine of the utility model is positively flushed alone.

[0259] As shown in the attached picture Fig.35 and Fig.37FAs shown, exemplarily, when the plane valve 1B of the water treatment machine according to the second embodiment of the 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, and 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 third opening 1103B of the plane valve 1B under the action of water pressure, and then flows to the sewage opening 1108B through the fourth positive flushing channel 7204B and is discharged.

[0260] As shown in the attached picture Fig.29M , Fig.29N , Fig.36 and Figure 37G As shown, the plane valve 1B of the water treatment machine according to the second embodiment of the utility model further has a water replenishment working position. When the plane valve 1B is in the water replenishment working position, the fifth channel 105B is connected with the second jet channel 1012B, thereby forming the water replenishment channel 7401B connected with the second fluid opening 1105B and the second jet opening 11012B respectively. FIG. 26A to FIG. 26I , Fig.29M , Fig.29N and Figure 37GAs shown, when the planar valve 1B is in the water replenishment working position, the sixth channel 106B is respectively connected with the first channel 101B and the second channel 102B, one end of the seventh channel 107B is connected with the eighth channel 108B, the other end of the seventh channel 107B is blocked by the first fluid control surface 1210B of the first fixed valve plate 121B, the third channel 103B and the first jet channel 1011B are respectively blocked by the second fluid control surface 1220B of the movable valve plate 122B, and the fourth channel 104B 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 utility model is in the water replenishment working position, the raw water flows into the second fluid opening 1105B of the valve body 10B of the plane valve 1B under the action of water pressure, flows into the second jet opening 11012B through the fifth channel 105B and the second jet channel 1012B, and then flows into the regeneration solution tank 31 through the injection port 183B of the ejector 18B, the salt absorption port 181B and the salt absorption pipe 184 in turn for water replenishment. Although the sixth channel 106B is connected to the first channel 101B and the second channel 102B respectively, since the sixth channel 106B is a conducting blind hole, the third channel 103B, the third opening 1103B, the second water treatment device 52, the first water treatment device 51, the first opening 1101B, the first channel 101B, the sixth channel 106B, the second channel 102B, the second opening 1102B and the first water treatment device 51 (the second water treatment device 52) form a flow channel isolated from the raw water, so that the water flow cannot flow through the first opening 1101B, the second opening 1102B and the third opening 1103B. In other words, although the sixth channel 106B is connected to the first channel 101B and the second channel 102B respectively, it cannot form a flow channel that allows water to flow through.

[0261] It is worth noting that the traditional plane valve adopts a valve core structure of a single moving valve plate and a single fixed valve plate. When in the water treatment working position, the moving valve plate often needs a conducting blind hole to guide the water flow to the water outlet. When the water flows in the 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, so that the flow rate of the water flow is significantly reduced. The plane valve 1B of the water treatment machine of the utility model adopts a three-valve plate structure. The water flow to the water outlet flows upward from the third channel 103B of the lower valve plate (the first fixed valve plate 121B) and the seventh channel 107B of the moving valve plate 122B. The outlet is in the eighth channel 108B of the upper valve plate (the second fixed valve plate 123B). The water flow direction changes slightly (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 the existing planar valve with a single fixed valve plate, the channel for controlling the flow direction of water provided on the fixed valve plate can only be provided on the single fixed valve plate, resulting in more through holes provided in the single fixed valve plate, and each through hole often occupies a relatively small space. In order to ensure the water flow rate, the diameter of the fixed valve plate of the planar valve is 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 moving valve plate 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 a thicker wall thickness. Since the diameter of the moving valve plate also needs to be increased accordingly, the thickness of the moving valve plate also needs to be increased accordingly, which 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 101B, the second channel 102B, the third channel 103B, the first jet channel 1011B and the second jet channel 1012B of the plane valve 1B of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121B, and the fourth channel 104B and the eighth channel 108B are respectively arranged on the second fixed valve plate 123B, thereby allowing the space occupied by each channel arranged on the first fixed valve plate 121B and the second fixed valve plate 123B to be enlarged and the water flow rate to be increased, especially the first channel 101B and the third channel 103B which serve as the main channel of the water treatment working position occupy a relatively large space in the first fixed valve plate 121B. In other words, the first channel 101B, the second channel 102B, the third channel 103B, the fourth channel 104B, the eighth channel 108B, the first jet channel 1011B and the second jet channel 1012B of the planar valve 1B of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121B and the second fixed valve plate 123B, which can significantly reduce the diameter of the fixed and movable valve plates (or the inner diameter of the valve cavity), the thickness of the movable valve plates and the wall thickness of the valve body of the planar valve, thereby reducing the manufacturing cost of the planar valve and making the entire planar valve structure lighter and easier to operate.
