Description

Technical Field

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

[0002] In modern industrial production, many industries require water with high cleanliness or low hardness. However, the cleanliness and hardness of many water sources, whether surface water or groundwater, do not meet the standards for industrial water. In order to obtain water with the expected water quality, the water from the water source (or raw water) needs to be treated. To treat raw water, generally, the raw water from the water source is first coarsely filtered to filter out larger particulate pollutants to obtain coarsely filtered water, and then the coarsely filtered water is further filtered using materials such as activated carbon to obtain cleaner purified water. Finally, the purified water is softened (or ultrafiltration or RO membrane filtration) to obtain softened water (or purified water with extremely high purity). Finally, the raw water undergoes multi-stage treatment (three or more stages of treatment) to obtain treated water with the expected water quality. For example, raw water is filtered and then ultrafiltered using water filtration equipment (using filter media such as quartz sand, activated carbon, or PP cotton) and ultrafiltration equipment (typically using ultrafiltration membrane fibers). Alternatively, raw water is filtered, ultrafiltered, and then treated with RO membranes using water filtration equipment, ultrafiltration equipment, and RO membrane purification equipment. Alternatively, raw water is coarsely filtered, filtered, and then softened using a prefilter, water filtration equipment, and a water softener. Furthermore, with the increasing improvement of living standards and a growing emphasis on health, people's demands for the quality of their domestic water are becoming increasingly stringent. Waterworks' extensive treatment of water received from the source is insufficient to remove all impurities, such as particulate contaminants (flocculated gels, silt, and even bacteria), which is increasingly insufficient to meet people's needs. Furthermore, the aging of the tap water supply network can introduce new contamination into tap water. Therefore, to further purify tap water and improve its cleanliness, a variety of water treatment methods are required.

[0003] However, most of the existing water treatment systems or water treatment equipment that can perform multi-stage treatment on raw water include multiple water treatment devices and multiple control valves that control the flow of water inside the corresponding water treatment devices. Because each water treatment device has a corresponding control valve, each control valve controls the water treatment function and flushing function of the corresponding water treatment device. Therefore, multiple control valves are connected in series. 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 utility model patent with application number CN202022865712.3 discloses a water treatment system having three filter material tanks connected in series, and controlling the flow direction of water and performing three-stage treatment on water by a single control valve, which solves the problem of too many control valves in the water treatment system. However, the structure of the water treatment system disclosed by the utility model patent is very simple. Although it can use three filter material tanks connected in series to perform multi-stage treatment on raw water, it cannot perform reverse flushing or forward flushing on the filter material tanks separately and individually. The structure of the water treatment system disclosed in this utility model patent means that when the three filter canisters connected in series are forward-flushed, the sewage generated by forward-flushing the first filter canister will flow into the second filter canister, and the sewage generated by forward-flushing the second filter canister will flow into the third filter canister. When the three filter canisters connected in series are reverse-flushed, the sewage generated by reverse-flushing the third filter canister will flow into the second filter canister, and the sewage generated by reverse-flushing the second filter canister will flow into the first filter canister. In other words, when the three filter canisters connected in series are forward-flushed, only the first filter canister may be cleaned, while the second and third filter canisters may not only not be cleaned, but may be further contaminated; and when the three filter canisters connected in series are reverse-flushed, only the third filter canister may be cleaned, while the second and first filter canisters may not only not be cleaned, but may be further contaminated. In particular, considering the effect of the three filter canisters connected in series in the water treatment system on the cascade reduction of the raw water pressure, the cleaning effect of forward-flushing and reverse-flushing the three filter canisters connected in series may be worse. In other words, the functional deficiencies of existing water treatment systems present a certain inconvenience to users. Finally, generally speaking, the control valve of a water treatment system utilizes a traditional dual-valve disc structure, requiring at least one diversion blind hole in the moving valve disc to provide treated water and redirect the water flow. However, as the water flows through the diversion blind hole, its direction changes 360 degrees, resulting in significant resistance and kinetic energy loss, significantly reducing the flow rate.

[0209] It can be understood that the forward flushing in this article refers to the flow direction of the water treatment device (the first water treatment device 51, the second water treatment device 52 or the third water treatment device 53) of the water treatment machine of the present invention when the water flow is flushing the water treatment device of the water treatment machine of the present invention, and the flow direction of the raw water through the water treatment device of the water treatment machine of the present invention when the water treatment device of the water treatment machine of the present invention treats the raw water is the same. Generally, the time for forward flushing the water treatment device of the water treatment machine of the present invention by using water flow is after backwashing, so as to flush away the wastewater generated by backwashing remaining in the water treatment device of the water treatment machine of the present invention.

When water flow, such as raw water flow, flows from the ejection port 182 of the ejector 18 to the ejection port 183 of the ejector 18, negative pressure occurs at the salt absorption port 181 of the ejector 18, so that the regeneration solution can flow from the salt absorption port 181 of the ejector 18 to the ejection port 183 of the ejector 18. Correspondingly, the salt absorption port 181 of the ejector 18 is communicated with the ejection port 182 and the ejection port 183 of the ejector 18 respectively.

When the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, the seventh channel 107 of the plane valve 1 is connected to the first channel 101, thereby forming channels connected to the second fluid opening 1107 and the first opening 1101 respectively. The first water treatment channel 7001 and the eighth channel 108 are respectively connected to the third channel 103 and the fourth channel 104, thereby forming the second water treatment channel 7002 respectively connected to the third opening 1103 and the fourth opening 1104, and the ninth channel 109 is respectively connected to the fifth channel 105 and the sixth channel 106, thereby forming the third water treatment channel 7003 respectively connected to the fifth opening 1105 and the first fluid opening 1106.

That is to say, when the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, no water flows out or 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; the eighth channel 108 is connected with the third channel 103 and the fourth channel 104 respectively, the third opening 1103 is connected with the second water outlet 522 of the second water treatment device 52, the fourth opening 1104 is connected with the third water inlet 531 of the third water treatment device 53, and the second water outlet 512 of the second water treatment device 52 is connected with the fourth opening 1104.

The treated water flows out of the first fluid opening 1106 and is provided. It can be understood that the three-stage series structure can better perform deep treatment on the raw water. In particular, the first water treatment material 515 of the first water treatment device 51, the second water treatment material 525 of the second water treatment device 52 and the third water treatment material 535 of the third water treatment device 53 can be set to different materials. For example, the first water treatment material 515 can be set to quartz sand as a coarse filtration material, the second water treatment material 525 can be set to granular activated carbon as an adsorption material, and the third water treatment material 535 can be set to softening resin for softening treatment.

[0218] As shown in the attached figure Figure 11A 、 Figure 11B and Figure 20AAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present invention is controlled to be in the water treatment working position, the raw water from the plane valve 1 flows into the valve chamber 110 from the second fluid opening 1107 of the valve body 10 under the action of water pressure, and then flows into the first opening 1101 through the seventh channel 107 and the first channel 101, and then flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51. Under the action of water pressure, the raw water is treated (for example, purified) by the first water treatment material 515. The generated primary treated water is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, 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, purified) by the second water treatment material 525 under the action of water pressure. For example, after purification treatment), the generated secondary treated water is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and then, under the action of water pressure, further passes through the third opening 1103 of the plane valve 1, the third channel 103, the eighth channel 108, the fourth channel 104, the fourth opening 1104, flows to the third water inlet 531 of the third water treatment device 53 and flows into the third water treatment device 53, and under the action of water pressure, is treated by the third water treatment material 535 (for example, softening treatment), and the generated tertiary treated water is collected by the third central pipe 534, and flows out from the third water outlet 532 of the third water treatment device 53 and flows to the fifth opening 1105 of the plane valve 1, and then is provided through the fifth channel 105, the ninth channel 109, the sixth channel 106 and the first fluid opening 1106.

[0219] As shown in the attached figure Figure 10C 、 Figure 10D 、 Figure 12 and Figure 20B As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a first backwash working position. When the plane valve 1 of the water treatment machine of the present invention is in the first backwash working position, the seventh channel 107 of the plane valve 1 is connected with the second channel 102, thereby forming the first backwash flow channel 7101 connected with the second fluid opening 1107 and the second opening 1102 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the first channel 101 respectively, thereby forming the second backwash flow channel 7102 connected with the sewage opening 11010 and the first opening 1101 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10C 、 Figure 10D and Figure 20BAs shown, when the plane valve 1 of the water treatment machine of the utility model is in the first backwash working position, the eighth channel 108 is respectively connected to the fifth channel 105 and the eleventh channel 1011, the third channel 103, the fourth channel 104, the twelfth channel 1012, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 is in the first backwash working position, although the eighth channel 108 of the plane valve 1 is connected to the fifth channel 105 and the eleventh channel 1011 respectively, the eighth channel 108 is a conducting blind hole, and the third channel 103, the fourth channel 104, the twelfth channel 1012, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow out from the second fluid opening 1220 of the plane valve 1. 107 flows into the seventh channel 107, and further flows through the second channel 102 and the second opening 1102 to the first water outlet 512 of the first water treatment device 51 and flows into the first water treatment device 51. The wastewater generated by backwashing the first water treatment device 51 flows from the first water inlet 511 of the first water treatment device 51 to the first opening 1101 of the plane valve 1, and is further discharged through the first channel 101, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 is connected to the fifth channel 105 and the eleventh channel 1011 respectively, since the fourth channel 104, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the eighth channel 108 is a conductive blind hole, the water does not flow through the flow channel formed by them.Correspondingly, when the plane valve 1 is in the first backwash working position, the third channel 103 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 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 blocked; the eighth channel 108 is connected to the fifth channel 105 and the eleventh channel 1011 respectively. Since the eighth channel 108 is a conducting blind hole, and the fourth channel 104 and the fourteenth channel 1 014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and since the fourth channel 104 and the eleventh channel 1011 are respectively connected to the fourth opening 1104, the fifth channel 105, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively connected to the fifth opening 1105, thereby preventing water from flowing through the fourth opening 1104 and the fifth opening 1105 of the plane valve 1, thereby preventing the flow of water in the second water treatment device 52 and the third water treatment device 53. In other words, although the eighth channel 108 is respectively connected to the fifth channel 105 and the eleventh channel 1011, the movable valve plate 122 blocks the raw water from flowing to the third channel 103, the fourth channel 104, the twelfth channel 1012, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015, thereby ensuring that only the first water treatment device 51 is reverse flushed.

[0220] It is worth noting that when the planar valve 1 is in the first backwash working position, the third channel 103, the fourth channel 104, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the movable valve plate 122. Although the eighth channel 108 is respectively connected to the fifth channel 105 and the eleventh channel 1011, the eighth channel 108 is a conducting blind hole, so that the third opening 1103, the fourth opening 1104 and the fifth opening 1105 are all blocked. That is, the third opening 1103, the fourth opening 1104, and the fifth opening 1105 are all blocked by the movable valve plate 122, so that no water flows in the second water treatment device 52. The third water treatment device 53 is isolated from the water flow, ensuring that only the first water treatment device 51 is backwashed. This increases the intensity of the raw water backwashing the first water treatment device 51 while preventing the generated sewage from flowing into the second water treatment device 52 and / or the third water treatment device 53. Therefore, when the flat valve 1 is in the first backwashing working position, the first water treatment device 51 of the water treatment machine of the present invention is backwashed alone.

[0221] As shown in the attached figure Figure 12 and Figure 20BAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the first backwash working position, the raw water from the plane valve 1 flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, and then flows from the first central pipe 514 to the first water treatment material 515 and backwashes the first water treatment material 515 under the action of water pressure. The generated sewage flows out from the first water inlet 511 of the first water treatment device 51, and under the action of water pressure, flows to the first opening 1101 of the plane valve 1, and then flows to the sewage opening 11010 through the second backwash channel 7102 and is discharged.

[0222] As shown in the attached figure Figure 10E 、 Figure 10F 、 Figure 13 and Figure 20C As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a second backwash working position. When the plane valve 1 of the water treatment machine of the present invention is in the second backwash working position, the seventh channel 107 of the plane valve 1 is connected with the third channel 103, thereby forming the third backwash flow channel 7103 connected with the second fluid opening 1107 and the third opening 1103 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the second channel 102 respectively, thereby forming the fourth backwash flow channel 7104 connected with the sewage opening 11010 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10E 、 Figure 10F and Figure 20C As shown, when the plane valve 1 of the water treatment machine of the present invention is in the second backwash working position, the eighth channel 108 is connected to the fifth channel 105 and the twelfth channel 1012 respectively, the first channel 101, the fourth channel 104, the eleventh channel 1011, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10E 、 Figure 10F and Figure 20CAs shown, specifically, when the plane valve 1 is in the second backwash working position, although the eighth channel 108 is connected to the fifth channel 105 and the twelfth channel 1012 respectively, since the eighth channel 108 is a conducting blind hole, and the first channel 101, the fourth channel 104, the eleventh channel 1011, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow out from the second fluid opening 1220 of the plane valve 1. 107 flows into the seventh channel 107, and further flows through the third channel 103 and the third opening 1103 to the second water outlet 522 of the second water treatment device 52 and flows into the second water treatment device 52. The wastewater generated by backwashing the second water treatment device 52 flows from the second water inlet 521 of the second water treatment device 52 to the second opening 1102 of the plane valve 1, and is further discharged through the second channel 102, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 of the planar valve 1 is respectively connected to the fifth channel 105 and the twelfth channel 1012, since the eighth channel 108 is a conductive blind hole, and the fourth channel 104, the eleventh channel 1011, the thirteenth channel 1013, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the water does not flow through the flow channel formed by them. Therefore, when the plane valve 1 is in the second backwash working position, the first channel 101 of the plane valve 1 is blocked by the second fluid control surface 1220 of the movable valve disc 122, thereby preventing water from flowing through the first opening 1101 of the 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 blocked; although the eighth channel 108 is connected to the fifth channel 105 and the twelfth channel 1012 respectively, since the eighth channel 108 is a conducting blind hole, and the fourth channel 104 and the eleventh channel 1011 are respectively blocked by the second fluid control surface 1220 of the movable valve disc 122 The fluid control surface 1220 is blocked, and since the fourth channel 104 and the eleventh channel 1011 are respectively connected to the fourth opening 1104, water is prevented from flowing through the fourth opening 1104 of the planar valve 1, so that no water flows in the fifth opening 1105. Therefore, the flow of water in the first water treatment device 51 and the third water treatment device 53 is blocked, and no water flows in the first jet opening 11012 connected to the twelfth channel 1012. Since the thirteenth channel 1013 is blocked by the second fluid control surface 1220 of the movable valve plate 122, no water flows in the second jet opening 11013.Accordingly, when the plane valve 1 is in the second backwash working position, the flow of water in the first water inlet 511 and the first water outlet 512 of the first water treatment device 51, and the third water inlet 531 and the third water outlet 532 of the third water treatment device 53 is also blocked, to ensure that only the second water treatment device 52 is backwashed, thereby increasing the intensity of the water flow for backwashing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51 and / or the third water treatment device 53. Therefore, when the plane valve 1 is in the second backwash working position, the second water treatment device 52 of the water treatment machine of the present invention is backwashed alone.

[0223] It is worth noting that when the planar valve 1 is in the second backwash working position, the first channel 101, the fourth channel 104, the eleventh channel 1011, the fourteenth channel 1014 and the fifteenth channel 1015 are respectively blocked by the movable valve plate 122, so that the first opening 1101 and the fourth opening 1104 are both blocked. Although the eighth channel 108 is respectively connected to the fifth channel 105 and the twelfth channel 1012, the eighth channel 108 is a conductive blind hole, so that no water flows in the fifth opening 1105. That is, no water flows through the first opening 1101, the fourth opening 1104, and the fifth opening 1105, so that no water flows through the first water treatment device 51 and the third water treatment device 53, ensuring that only the second water treatment device 52 is backwashed. This increases the intensity of the flow of raw water backwashing the second water treatment device 52 while preventing the generated sewage from flowing into the first water treatment device 51 and / or the third water treatment device 53. 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 present invention is backwashed alone.

[0224] As shown in the attached figure Figure 13 and Figure 20C As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the second backwash working position, the raw water from the plane valve 1 flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, and then flows from the second central pipe 524 to the second water treatment material 525 and backwashes the second water treatment material 525 under the action of water pressure. The generated sewage flows out from the second water inlet 521 of the second water treatment device 52, and under the action of water pressure, flows to the second opening 1102 of the first valve body 11 of the plane valve 1, and then flows to the sewage opening 11010 through the fourth backwash channel 7104 and is discharged.

[0225] As shown in the attached figure Figure 10G 、 Figure 10H 、 Figure 14 and Figure 20D As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a third backwash working position. When the plane valve 1 of the water treatment machine of the present invention is in the third backwash working position, the seventh channel 107 is connected to the fourteenth channel 1014, thereby forming the fifth backwash flow channel 7105 connected to the second fluid opening 1107 and the fifth opening 1105 respectively, and the ninth channel 109 is connected to the tenth channel 1010 and the eleventh channel 1011 respectively, thereby forming the sixth backwash flow channel 7106 connected to the sewage opening 11010 and the fourth opening 1104 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10G 、 Figure 10H and Figure 20D As shown, when the flat valve 1 of the water treatment machine of the present invention is in the third backwash working position, the eighth channel 108 is connected to the second channel 102 and the third channel 103 respectively, the first channel 101, the fourth channel 104, the fifth channel 105, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 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 10G 、 Figure 10H and Figure 20DAs shown, specifically, when the plane valve 1 is in the third backwash working position, although the eighth channel 108 is connected to the second channel 102 and the third channel 103 respectively, since the eighth channel 108 is a conducting blind hole, and the first channel 101, the fourth channel 104, the fifth channel 105, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow from the second fluid opening 1107 of the plane valve 1. The wastewater flows into the seventh channel 107, and further flows through the fourteenth channel 1014 and the fifth opening 1105 to the third water outlet 532 of the third water treatment device 53 and flows into the third water treatment device 53. The wastewater generated by backwashing the third water treatment device 53 flows from the third water inlet 531 of the third water treatment device 53 to the fourth opening 1104 of the plane valve 1, and is further discharged through the eleventh channel 1011, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 is respectively connected to the second channel 102 and the third channel 103, the eighth channel 108 is a conducting blind hole, and since the first channel 101 is blocked by the movable valve plate 122, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102 (and the second channel 102), the second water treatment device 52, the third opening 1103, the third channel 103, the eighth channel 108 and the second channel 102 form a closed connecting channel isolated from the raw water, and water cannot flow freely therein. In other words, when the planar valve 1 is in the third backwashing position, the flow of water in the first opening 1101, the second opening 1102, and the third opening 1103 of the first valve body 11 of the planar valve 1 is blocked. Therefore, even if the eighth passage 108 of the planar valve 1 is connected to the second passage 102 and the third passage 103, respectively, no flow path is formed to allow water to flow through. Therefore, the flow of water in the first water treatment device 51 and the second water treatment device 52 is blocked. Accordingly, when the plane valve 1 is in the third backwashing working position, the flow of water in the first water inlet 511 and the first water outlet 512 of the first water treatment device 51, and the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is also blocked, to ensure that only the third water treatment device 53 is backwashed, and while increasing the intensity of the water flow for backwashing the third water treatment device 53, the generated sewage is prevented from flowing into the first water treatment device 51 and / or the second water treatment device 52. Therefore, when the plane valve 1 is in the third backwashing working position, the third water treatment device 53 of the water treatment machine of the present invention is backwashed alone.

[0226] It is worth noting that when the plane valve 1 is in the third backwash working position, the first channel 101 is blocked by the movable valve plate 122, so that the first opening 1101 is blocked. Even if the eighth channel 108 is connected to the second channel 102 and the third channel 103 respectively, the eighth channel 108 is a conducting blind hole, thereby isolating the first water treatment device 51 and the second water treatment device 52 from the water flow, and no water flows out or in through the first opening 1101, the second opening 1102 and the third opening 1103, so as to ensure that only the third water treatment device 53 is backwashed, thereby increasing the intensity of the raw water flow for backwashing the third water treatment device 53 while preventing the generated sewage from flowing into the first water treatment device 51 and / or the second water treatment device 52. Therefore, when the plane valve 1 is in the third backwash working position, the third water treatment device 53 of the water treatment machine of the present invention is backwashed separately.

[0227] As shown in the attached figure Figure 14 and Figure 20D As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the third backwash working position, the raw water from the plane valve 1 flows into the third water treatment device 53 from the third water outlet 532 of the third water treatment device 53 under the action of water pressure, and then flows from the third central pipe 534 to the third water treatment material 535 and backwashes the third water treatment material 535 under the action of water pressure. The generated sewage flows out from the third water inlet 531 of the third water treatment device 53, and under the action of water pressure, flows to the fourth opening 1104 of the first valve body 11 of the plane valve 1, and then flows to the sewage opening 11010 through the sixth backwash channel 7106 and is discharged.

[0228] As shown in the attached figure Figure 10I 、 Figure 10J 、 Figure 15 and Figure 20E As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a first positive flushing working position. When the plane valve 1 of the water treatment machine of the present invention is in the first positive flushing working position, the seventh channel 107 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 1107 and the first opening 1101 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the second channel 102 respectively, thereby forming the second positive flushing flow channel 7202 connected with the sewage opening 11010 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10I 、 Figure 10J and Figure 20EAs shown, when the flat valve 1 of the water treatment machine of the present invention is in the first positive flushing working position, the eighth channel 108 is connected to the first channel 101 and the fourteenth channel 1014 respectively, the third channel 103, the fourth channel 104, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10I 、 Figure 10J and Figure 20EAs shown, when the plane valve 1 is in the first positive flushing working position, although the eighth channel 108 of the plane valve 1 is connected to the first channel 101 and the fourteenth channel 1014 respectively, since the eighth channel 108 is a conducting blind hole, and the third channel 103, the fourth channel 104, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow from the first channel 101 to the fourth channel 1014 of the plane valve 1. The second fluid opening 1107 flows into the seventh channel 107, and further flows through the first channel 101 and the first opening 1101 to the first water inlet 511 of the first water treatment device 51 and flows into the first water treatment device 51. The wastewater generated by forward flushing the first water treatment device 51 flows from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the plane valve 1, and is further discharged through the second channel 102, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 of the plane valve 1 is connected to the first channel 101 and the fourteenth channel 1014 respectively, since the eighth channel 108 is a conducting blind hole, and the fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fifteenth channel 1015 are blocked by the second fluid control surface 1220 of the movable valve plate 122, and since the fourth channel 104 and the eleventh channel 1011 are connected to the fourth opening 1104 respectively, the fifth channel 105 is blocked by the second fluid control surface 1220 of the movable valve plate 122. , the fourteenth channel 1014 and the fifteenth channel 1015 are respectively connected to the fifth opening 1105, thereby preventing water from flowing through the fourth opening 1104 and the fifth opening 1105 of the plane valve 1; because the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, the wastewater generated by forward flushing the first water treatment device 51 is prevented from flowing out of 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. Correspondingly, when the planar valve 1 is in the first positive flushing working position, the eighth channel 108 is connected to the first channel 101 and the fourteenth channel 1014 respectively, and the third channel 103, the fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the third opening 1103, the fourth opening 1104 and the fifth opening 1105 of the planar valve 1. Therefore, the water flow is prevented from flowing through the third opening 1103, the fourth opening 1104 and the fifth opening 1105 of the planar valve 1, thereby preventing the flow of water in the second water treatment device 52 and the third water treatment device 53.In other words, although the eighth channel 108 is respectively connected to the first channel 101 and the fourteenth channel 1014, the movable valve plate 122 blocks the raw water from flowing to the third channel 103, the fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fifteenth channel 1015, so that the water flows only to the first water treatment device 51 and the first water treatment device 51 is flushed forward.

[0229] It is worth noting that when the planar valve 1 is in the first positive flushing working position, the third channel 103, the fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fifteenth channel 1015 are respectively blocked by the movable valve plate 122. Although the eighth channel 108 is respectively connected to the first channel 101 and the fourteenth channel 1014, the eighth channel 108 is a conductive blind hole, so that no water flows out or in through the third opening 1103, the fourth opening 1104 and the fifth opening 1105, so that no water flows in the second water treatment device 52 and the third water treatment device 53, to ensure that only the first water treatment device 51 is positively flushed, thereby increasing the intensity of the water flow of the raw water for positive flushing the first water treatment device 51, and preventing the generated sewage from flowing into the second water treatment device 52 and / or the third water treatment device 53. 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 present invention is flushed forward alone.

[0230] As shown in the attached figure Figure 15 and Figure 20E As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the first positive flushing working position, the raw water from the plane valve 1 flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then positively flushes the first water treatment material 515 under the action of water pressure. The generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51, and flows to the second opening 1102 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11010 through the second positive flushing channel 7202 and is discharged.

[0231] As shown in the attached figure Figure 10K 、 Figure 10L 、 Figure 16 and Figure 20FAs shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a second positive flushing working position. When the plane valve 1 of the water treatment machine of the present invention is in the second positive flushing working position, the seventh channel 107 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 1107 and the second opening 1102 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the third channel 103 respectively, thereby forming the fourth positive flushing flow channel 7204 connected with the sewage opening 11010 and the third opening 1103 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10K 、 Figure 10L and Figure 20F As shown, when the flat valve 1 of the water treatment machine of the present invention is in the second positive flushing working position, the eighth channel 108 is connected to the first channel 101 and the fifteenth channel 1015 respectively, the fourth channel 104, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012, the thirteenth channel 1013 and the fourteenth channel 1014 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in the accompanying drawings 7A to 7I 、 Figure 10K 、 Figure 10L and Figure 20FAs shown, specifically, when the plane valve 1 is in the second positive flushing working position, although the eighth channel 108 of the plane valve 1 is connected to the first channel 101 and the fifteenth channel 1015 respectively, since the eighth channel 108 is a conducting blind hole, and the fourth channel 104, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012, the thirteenth channel 1013 and the fourteenth channel 1014 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow from the second fluid control surface 1220 of the plane valve 1. The opening 1107 flows into the seventh channel 107, and further flows through the second channel 102 and the second opening 1102 to the second water inlet 521 of the second water treatment device 52 and into the second water treatment device 52. The wastewater generated by forward flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the third opening 1103 of the plane valve 1, and is further discharged through the third channel 103, the ninth channel 109, the tenth channel 1010, and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 is connected to the first channel 101 and the fifteenth channel 1015 respectively, because the eighth channel 108 is a conductive blind hole, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1 is in the second positive flushing working position, because the eighth channel 108 is connected to the first channel 101 and the fifteenth channel 1015 respectively, the second channel 102, the second opening 1102, the first water treatment device 51, the first opening 1101, the first channel 101, the eighth channel 108, the fifteenth channel 1015, the fifth opening 1105, the third water treatment device 53, the fourth opening 1104 and the fourth channel 104 (the eleventh channel 1011) form a flow channel, but due to the fourth channel The fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fourteenth channel 1014 are all blocked by the movable valve disc 122, so that the fourth opening 1104 is blocked, so that the water flow cannot flow through the flow path formed by the second channel 102, the second opening 1102, the first water treatment device 51, the first opening 1101, the first channel 101, the eighth channel 108, the fifteenth channel 1015, the fifth opening 1105, the third water treatment device 53, the fourth opening 1104 and the fourth channel 104 (the eleventh channel 1011). Further, when the plane valve 1 is in the second positive flushing working position, the fourth channel 104 and the eleventh channel 1011 are all blocked by the movable valve disc 122, so that the water flow cannot flow from the fourth opening 1104 to the third water treatment device 53, or from the third water treatment device 53 to the fourth opening 1104.In other words, the flow of flushing water flowing out of the second opening 1102 to the first water outlet 512 of the first water treatment device 51 is blocked, so that the water flow is blocked from flowing through the first water treatment device 51 and the third water treatment device 53, thereby ensuring that only the second water treatment device 52 is flushed in the forward direction.

[0232] It is worth noting that when the planar valve 1 is in the second positive flushing working position, the fourth channel 104, the fifth channel 105, the eleventh channel 1011 and the fourteenth channel 1014 are respectively blocked by the movable valve plate 122. Although the eighth channel 108 is respectively connected to the first channel 101 and the fifteenth channel 1015, the eighth channel 108 is a conductive blind hole, so that no water flows out or in through the first opening 1101, the fourth opening 1104 and the fifth opening 1105. That is to say, there is no water flowing in the first water treatment device 51 and the third water treatment device 53 to ensure that only the second water treatment device 52 is positively flushed, thereby increasing the intensity of the water flow of the raw water for positive flushing the second water treatment device 52, while also preventing the generated sewage from flowing into the first water treatment device 51 and / or the third water treatment device 53. 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 present invention is flushed forward alone.

[0233] As shown in the attached figure Figure 16 and Figure 20F As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the second positive flushing working position, the raw water from the plane valve 1 flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then positively flushes the second water treatment material 525 under the action of water pressure. The generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, and flows to the third opening 1103 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11010 through the fourth positive flushing channel 7204 and is discharged.

[0234] As shown in the attached figure Figure 10M 、 Figure 10N 、 Figure 17 and Figure 20GAs shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a third positive flushing working position. When the plane valve 1 of the water treatment machine of the present invention is in the third positive flushing working position, the seventh channel 107 of the plane valve 1 is connected to the eleventh channel 1011, thereby forming the fifth positive flushing flow channel 7205 connected to the second fluid opening 1107 and the fourth opening 1104 respectively, and the ninth channel 109 is connected to the tenth channel 1010 and the fourteenth channel 1014 respectively, thereby forming the sixth positive flushing flow channel 7206 connected to the sewage opening 11010 and the fifth opening 1105 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10M 、 Figure 10N and Figure 20G As shown, when the flat valve 1 of the water treatment machine of the present invention is in the third positive flushing working position, the eighth channel 108 is connected to the first channel 101 and the second channel 102 respectively, the third channel 103, the fourth channel 104, the fifth channel 105, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 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 10M 、 Figure 10N and Figure 20GAs shown, specifically, when the plane valve 1 is in the third positive flushing working position, although the eighth channel 108 is connected to the first channel 101 and the second channel 102 respectively, since the eighth channel 108 is a conducting blind hole, and the third channel 103, the fourth channel 104, the fifth channel 105, the twelfth channel 1012, the thirteenth channel 1013 and the fifteenth channel 1015 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow from the second fluid opening 1107 of the plane valve 1. The wastewater flows into the seventh channel 107, and further flows through the eleventh channel 1011 and the fourth opening 1104 to the third water inlet 531 of the third water treatment device 53 and flows into the third water treatment device 53. The wastewater generated by forward flushing the third water treatment device 53 flows from the third water outlet 532 of the third water treatment device 53 to the fifth opening 1105 of the plane valve 1, and is further discharged through the fourteenth channel 1014, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 of the plane valve 1 under the action of water pressure. In other words, although the eighth channel 108 is respectively connected to the first channel 101 and the second channel 102, the eighth channel 108 is a conducting blind hole, and since the third channel 103 is blocked by the movable valve plate 122, the eighth channel 108, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102 (the second channel 102, the eighth channel 108), the second water treatment device 52, the third opening 1103 and the third channel 103 form a closed connecting channel isolated from the raw water, and water cannot flow freely therein. Accordingly, when the plane valve 1 is in the third positive flushing position, the flow of water in the first opening 1101, the second opening 1102, and the third opening 1103 of the first valve body 11 of the plane valve 1 is blocked, so that even if the eighth channel 108 of the plane valve 1 is connected to the first channel 101 and the second channel 102, respectively, no flow path is formed to allow water to flow. Therefore, the flow of water in the first water treatment device 51 and the second water treatment device 52 is blocked. Accordingly, when the plane valve 1 is in the third positive flushing position, the flow of water in the first water inlet 511 and the first water outlet 512 of the first water treatment device 51, and the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is also blocked, to ensure that only the third water treatment device 53 is forward flushed, and while increasing the intensity of the water flow for forward flushing the third water treatment device 53, prevent the generated sewage from flowing into the first water treatment device 51 and / or the second water treatment device 52. Therefore, when the plane valve 1 is in the third positive flushing position, the third water treatment device 53 of the water treatment machine of the present invention is forward flushed alone.

[0235] It is worth noting that when the plane valve 1 is in the third positive flushing working position, the third channel 103 is blocked by the movable valve plate 122, so that the third opening 1103 is blocked. Even if the eighth channel 108 is connected to the first channel 101 and the second channel 102 respectively, the eighth channel 108 is a conductive blind hole, thereby isolating the first water treatment device 51 and the second water treatment device 52 from the water flow, and no water flows out or in through the first opening 1101, the second opening 1102 and the third opening 1103, so as to ensure that only the third water treatment device 53 is positively flushed, thereby increasing the intensity of the raw water flow for positively flushing the third water treatment device 53, and preventing the generated sewage from flowing into the first water treatment device 51 and / or the second water treatment device 52. Therefore, when the plane valve 1 is in the third positive flushing working position, the third water treatment device 53 of the water treatment machine of the utility model is separately positively flushed.

[0236] As shown in the attached figure Figure 17 and Figure 20G As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the third positive flushing working position, the raw water from the plane valve 1 flows into the third water treatment device 53 from the third water inlet 531 of the third water treatment device 53 under the action of water pressure, and then positively flushes the third water treatment material 535 under the action of water pressure. The generated sewage is collected by the third central pipe 534 and flows out from the third water outlet 532 of the third water treatment device 53, and flows to the fifth opening 1105 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11010 through the sixth positive flushing channel 7206 and is discharged.

[0237] As shown in the attached figure Figure 10O 、 Figure 10P 、 Figure 18A 、 Figure 18B and Figure 20H As shown, the flat valve 1 of the water treatment machine according to the first embodiment of the present invention further has a regeneration working position. When the flat valve 1 is in the regeneration working position, the seventh channel 107 is connected to the twelfth channel 1012, thereby forming the first regeneration flow channel 7301 connected to the second fluid opening 1107 and the first jet opening 11012 respectively. The eighth channel 108 is connected to the thirteenth channel 1013 and the eleventh channel 1011 respectively, thereby forming the second regeneration flow channel 7302 connected to the second jet opening 11013 and the fourth opening 1104 respectively. The ninth channel 109 is connected to the tenth channel 1010 and the fifteenth channel 1015 respectively, thereby forming the third regeneration flow channel 7303 connected to the sewage opening 11010 and the fifth opening 1105 respectively. As shown in the accompanying drawings 7A to 7I 、 Figure 10O 、 Figure 10P and Figure 20H As shown, when the planar valve 1 is in the regeneration working position, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105 and the fourteenth channel 1014 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 of the water treatment machine of the present invention is in the regeneration working position, the raw water flows into the second fluid opening 1107 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 seventh channel 107 and the twelfth channel 1012) to the first jet opening 11012 of the first valve body 11, and then flows into the ejection port 182 of the ejector 18. After the ejection of the ejector 18, the salt solution (such as sodium chloride solution) from the salt absorption port 181 is mixed to form a regeneration solution. The regeneration solution flows into the second jet opening 111 of the first valve body 11 through the ejection port 183 of the ejector 18. 013, then flows into the fourth opening 1104 of the first valve body 11 through the second regeneration flow channel 7302 (the thirteenth channel 1013, the eighth channel 108 and the eleventh channel 1011), and the regeneration solution flows into the third water treatment device 53 from the third water inlet 531, regenerating the third water treatment material 535 downstream, such as after softening the resin. The wastewater generated after regeneration flows out from the third water outlet 532, and then flows out through the fifth opening 1105 of the first valve body 11, the third regeneration flow channel 7303 (the fifteenth channel 1015, the ninth channel 109 and the tenth channel 1010) and the sewage outlet 11010 in sequence. As shown in the accompanying drawings 7A to 7I 、 Figure 10O 、 Figure 10P and Figure 20HAs shown, specifically, when the plane valve 1 is in the regeneration working position, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105 and the fourteenth channel 1014 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 seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and further through the twelfth channel 1012, the first jet opening 11012, the ejector 18, the second jet opening 11013, the thirteenth channel 101 3. The eighth channel 108, the eleventh channel 1011 and the fourth opening 1104 flow toward the third water inlet 531 of the third water treatment device 53 and into the third water treatment device 53, regenerating the softening material (for example, softening resin) of the third water treatment device 53 downstream, and the generated wastewater flows from the third water outlet 532 of the third water treatment device 53 to the fifth opening 1105 of the plane valve 1, and is further discharged through the fifteenth channel 1015, the ninth channel 109, the tenth channel 1010 and the sewage opening 11010 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, the second channel 102 and the third channel 103 are all blocked by the movable valve plate 122, thereby preventing water from flowing through the first opening 1101, the second opening 1102 and the third opening 1103 of the planar valve 1; the water flow is prevented from flowing through the first opening 1101, the second opening 1102 and the third opening 1103 of the planar valve 1, thereby preventing the flow of water in the first water treatment device 51 and the second water treatment device 52, thereby ensuring that only the third water treatment device 53 is regenerated downstream.

[0238] It is worth noting that when the planar valve 1 is in the regeneration working position, the first channel 101, the second channel 102, and the third channel 103 are respectively blocked by the movable valve plate 122, so that the first opening 1101, the second opening 1102 and the third opening 1103 are blocked, that is, the first water treatment device 51 and the second water treatment device 52 are isolated from the water flow to ensure that only the third water treatment device 53 is regenerated downstream, thereby increasing the intensity of the water flow of the regeneration solution for downstream regeneration of the third water treatment device 53, while also preventing the generated sewage from flowing to the first water treatment device 51 and / or the second water treatment device 52. 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 and / or the second water treatment device 52, because in actual use, the first water treatment device 51 or the second water treatment device 52 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 or the second water treatment device 52. This 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 third water treatment device 53 of the water treatment machine of the present invention is regenerated separately downstream.

[0239] As shown in the attached figure Figure 18A 、 Figure 18B and Figure 20H As shown, exemplarily, when the plane valve 1 of the water treatment machine according to the first embodiment of the present utility model is controlled to be in the regeneration working position, the raw water from the plane valve 1 is mixed with the salt solution from the ejector 18 under the action of water pressure to form a regeneration solution, which flows into the third water treatment device 53 from the third water inlet 531 of the third water treatment device 53, and then regenerates the third water treatment material 535 downstream under the action of water pressure. The generated sewage is collected by the third central pipe 534 and flows out from the third water outlet 532 of the third water treatment device 53, and flows to the fifth opening 1105 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11010 through the third regeneration flow channel 7303 and is discharged.

[0240] As shown in the attached figure Figure 10Q 、 Figure 10R 、 Figure 19 and Figure 20I As shown, the plane valve 1 of the water treatment machine according to the first embodiment of the present invention further has a water replenishment working position. When the plane valve 1 is in the water replenishment working position, the seventh channel 107 is connected to the thirteenth channel 1013, thereby forming the water replenishment flow channel 7401 connected to the second fluid opening 1107 and the second jet opening 11013 respectively. 7A to 7I 、 Figure 10Q 、 Figure 10R and Figure 20I As shown, when the planar valve 1 is in the water replenishment working position, the eighth channel 108 is respectively connected to the first channel 101 and the fifteenth channel 1015, the ninth channel 109 is respectively connected to the tenth channel 1010 and the fourth channel 104, the second channel 102, the third channel 103, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012 and the fourteenth channel 1014 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 of the water treatment machine of the present invention is in the water replenishment working position, the raw water flows into the second fluid opening 1107 of the valve body 10 of the plane valve 1 under the action of water pressure, flows into the second jet opening 11013 through the seventh channel 107 and the thirteenth channel 1013, 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 eighth channel 108 is connected to the first channel 101 and the fifteenth channel 1015 respectively, and the ninth channel 109 is connected to the tenth channel 1010 and the fourth channel 104 respectively, since the second channel 102, the third channel 103, the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012 and the fourteenth channel 1014 are blocked by the movable valve plate 122 respectively, the eighth channel 108 is a conducting blind hole, and the ninth channel 109 is a conducting through hole, so that the tenth channel 1010, the ninth channel 109, the fourth channel 104 (the eleventh channel 1011), the fourth open hole The opening 1104, the third water treatment device 53, the fifth opening 1105, the fifteenth channel 1015 (the fifth channel 105, the fourteenth channel 1014), the eighth channel 108, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102, the second channel 102, the second water treatment device 52, the third opening 1103, and the third channel 103 form a flow channel isolated from the raw water, so that water cannot flow through the first opening 1101, the second opening 1102, the third opening 1103, the fourth opening 1104, and the fifth opening 1105. In other words, although the eighth channel 108 is connected to the first channel 101 and the fifteenth channel 1015 respectively, and the ninth channel 109 is connected to the tenth channel 1010 and the fourth channel 104 respectively, they cannot form a flow channel that allows water to flow.

[0241] It is worth noting that conventional planar valves utilize a valve core structure with a single movable valve disc and a single fixed valve disc. The movable valve disc often requires a conducting blind hole to guide the water flow toward the outlet. When water flows through the guiding blind hole, the flow direction changes 360 degrees, causing significant resistance to the water flow and a significant loss of kinetic energy, resulting in a significant reduction in the water flow rate. The planar valve 1 of the water treatment machine of the present invention utilizes a three-valve disc structure. Water flowing toward the outlet flows upward from the lower valve disc (first fixed valve disc 121), with the outlet located on the upper valve disc (second fixed valve disc 123). This results in a relatively small (approximate) change in the water flow direction, and the water flow encounters relatively little resistance during the change in direction, significantly reducing the loss of water flow rate. Furthermore, in existing planar valves with a single fixed valve disc, the channel for controlling the flow direction of the water flow, which is provided on the fixed valve disc, can only be provided on the single fixed valve disc. To ensure the water flow rate, the diameter of the fixed valve disc of the planar valve and the overall volume of the planar valve are large. The larger the diameter of a planar valve, the more difficult it is to ensure the stability of the movable valve disc during rotation. To ensure the stability of the entire planar valve, the cross-sectional area of ​​the planar valve increases, requiring a thicker valve body and a corresponding increase in the thickness of the movable valve disc. This not only increases the manufacturing cost of the planar valve, but also makes the entire planar valve heavier and more difficult to operate.

[0242] As shown in the attached figure Figures 6C to 10RAs shown, the first channel 101 of the planar valve 1 of the water treatment machine according to the first embodiment of the present utility model has a first connecting portion 10101 and a second connecting portion 10102, wherein the first connecting portion 10101 of the first channel 101 is connected to the first opening 1101, and the second connecting portion 10102 of the first channel 101 is connected to the first opening 1101. Preferably, the first channel 101 of the planar valve 1 further has a third communication portion 10103 extending between the first communication portion 10101 and the second communication portion 10102. The first communication portion 10101 of the first channel 101 is connected to the first opening 1101, and the second communication portion 10102 of the first channel 101 is connected to the first communication portion 10101 via the third communication portion 10103. In other words, the second communication portion 10102 of the first channel 101 is connected to the first opening 1101 via the third communication portion 10103 and the first communication portion 10101. Preferably, the fifteenth channel 1015 of the planar valve 1 is disposed outside the third communication portion 10103. The second channel 102 of the planar valve 1 has a first conducting portion 10201 and a second conducting portion 10202 , wherein the first conducting portion 10201 of the second channel 102 is connected to the second opening 1102 , and the second conducting portion 10202 of the second channel 102 is connected to the second opening 1102 . Preferably, the second channel 102 of the planar valve 1 further has a third conducting portion 10203 extending between the first conducting portion 10201 and the second conducting portion 10202.
