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 (three 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, 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, and each control valve controls the water treatment function and flushing function of the corresponding water treatment device, so 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, which has three filter material tanks connected in series, and controls the flow direction of water and performs three-stage treatment on water through 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 separately and individually perform reverse flushing or forward flushing on the filter material tank. The structure of the water treatment system disclosed in the utility model patent means that when the three filter material tanks connected in series are forwardly flushed, the sewage generated by forward flushing the first filter material tank will flow into the second filter material tank, and the sewage generated by forward flushing the second filter material tank will flow into the third filter material tank. When the three filter material tanks connected in series are reversely flushed, the sewage generated by reverse flushing the third filter material tank will flow into the second filter material tank, and the sewage generated by reverse flushing the second filter material tank will flow into the first filter material tank. In other words, when the three filter material tanks connected in series are forwardly flushed, only the first filter material tank may be cleaned, while the second and third filter material tanks may not only not be cleaned, but will be further polluted; and when the three filter material tanks connected in series are reversely flushed, only the third filter material tank may be cleaned, while the second and first filter material tanks may not only not be cleaned, but will be further polluted. In particular, considering the effect of the three filter material tanks connected in series in the water treatment system on the step-by-step reduction of the water pressure of the raw water, the cleaning effect of forward flushing and reverse flushing of the three filter material tanks connected in series may be worse. In other words, the lack of functions of the existing water treatment machine has brought certain inconveniences to the users. Finally, the control valve of the water treatment machine disclosed in the utility model patent adopts a traditional double valve plate structure, which requires at least one diversion blind hole to be set in the moving valve plate to change the flow direction of the water. However, when the water flows in the diversion 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.

Accordingly, the water treatment machine of the utility model and the control valve for the water treatment machine have a brand-new and unique spatial structure, which is a unique innovative design in the world, thereby creatively solving the problem that a single control valve can be used to control the three water treatment devices to be connected in series to perform multi-stage water treatment on the raw water, and can also control the raw water to flush the three water treatment devices separately and individually in reverse or forward directions. Therefore, the control valve for the water treatment machine of the utility model solves the biggest obstacle to the use of three water treatment devices in series.

Correspondingly, when the control valve 1 is in the first positive flushing working position, the raw water flows in from the second fluid opening 1108 of the valve body 10 of the control valve 1 under the action of water pressure, flows to the first opening 1101 through the first positive flushing channel 7201, and further flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51. The sewage after positive flushing of the first water treatment device 51 flows out from the first water outlet 512 of the first water treatment device 51, and is then discharged through the second opening 1102 of the control valve 1, the second positive flushing channel 7202 and the sewage opening 11012. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the utility model is configured to prevent raw water from flowing from the second fluid opening 1108 of the valve body 10 of the control valve 1 to the third opening 1103, the fourth opening 1104, the fifth opening 1105 and the sixth opening 1106 when the control valve 1 is controlled to be in the first positive flushing working position. More preferably, when the control valve 1 of the water treatment machine of the utility model is controlled to be in the first positive flushing working position, the flow of water in the third opening 1103, the fourth opening 1104, the fifth opening 1105 and the sixth opening 1106 is prevented, so that the flow of water in the second water treatment device 52 and the third water treatment device 53 is prevented. More specifically, when the control valve 1 of the water treatment machine according to the embodiment of the utility model is controlled to be in the first positive flushing working position, water cannot flow from the third opening 1103 or the fourth opening 1104 of the first valve body 11 to the second water treatment device 52; water cannot flow from the fifth opening 1105 or the sixth opening 1106 of the first valve body 11 to the third water treatment device 53, thereby ensuring that raw water can and can only positively flush the first water treatment device 51. It can be understood that when the control valve 1 of the water treatment machine according to the embodiment of the utility model is controlled to be in the first positive flushing working state, the water treatment machine of the utility model is controlled to be in its first positive flushing working state.

[0110] As shown in the attached picture Fig.16 and Fig.18FAs shown, the control valve 1 of the water treatment machine according to the embodiment of the utility model has a second positive flushing working position, wherein when the control valve 1 is in the second positive flushing working position, the valve core 12 of the control valve 1 forms a third positive flushing channel 7203 and a fourth positive flushing channel 7204, wherein the third positive flushing channel 7203 is respectively connected to the second fluid opening 1108 and the third opening 1103, and the fourth positive flushing channel 7204 is respectively connected to the sewage opening 11012 and the fourth opening 1104. Correspondingly, when the control valve 1 is in the second positive flushing working position, the raw water flows in from the second fluid opening 1108 of the valve body 10 of the control valve 1 under the action of water pressure, flows to the third opening 1103 through the third positive flushing channel 7203, and further flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52. The sewage after positive flushing the second water treatment device 52 flows out from the second water outlet 522 of the second water treatment device 52, and is then discharged through the fourth opening 1104 of the control valve 1, the fourth positive flushing channel 7204 and the sewage opening 11012. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the utility model is configured to prevent raw water from flowing from the second fluid opening 1108 of the valve body 10 of the control valve 1 to the first opening 1101, the second opening 1102, the fifth opening 1105 and the sixth opening 1106 when the control valve 1 is controlled to be in the second positive flushing working position. More preferably, when the control valve 1 of the water treatment machine of the utility model is controlled to be in the second positive flushing working position, the flow of water in the first opening 1101, the second opening 1102, the fifth opening 1105 and the sixth opening 1106 is prevented, so that the flow of water in the first water treatment device 51 and the third water treatment device 53 is prevented. More specifically, when the control valve 1 of the water treatment machine according to the embodiment of the utility model is controlled to be in the second positive flushing 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; water cannot flow from the fifth opening 1105 and the sixth opening 1106 of the first valve body 11 to the third water treatment device 53, thereby ensuring that raw water can and can only positively flush the second water treatment device 52. It can be understood that when the control valve 1 of the water treatment machine according to the embodiment of the utility model is controlled to be in the second positive flushing working state, the water treatment machine of the utility model is controlled to be in its second positive flushing working state.

Correspondingly, when the control valve 1 is in the third positive flushing working position, the raw water flows in from the second fluid opening 1108 of the valve body 10 of the control valve 1 under the action of water pressure, flows to the fifth opening 1105 through the fifth positive flushing channel 7205, and further flows into the third water treatment device 53 from the third water inlet 531 of the third water treatment device 53. The sewage after positive flushing the third water treatment device 53 flows out from the third water outlet 532 of the third water treatment device 53, and is then discharged through the sixth opening 1106 of the control valve 1, the sixth positive flushing channel 7206 and the sewage opening 11012. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the utility model is configured to prevent raw water from flowing from the second fluid opening 1108 of the valve body 10 of the control valve 1 to the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 when the control valve 1 is controlled to be in the third positive flushing working position. More preferably, when the control valve 1 of the water treatment machine of the utility model is controlled to be in the third positive flushing working position, the flow of water in the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 is prevented, 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 embodiment of the utility model is controlled to be in the third positive flushing 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; water cannot flow from the third opening 1103 or the fourth opening 1104 of the first valve body 11 to the second water treatment device 52, thereby ensuring that raw water can and can only positively flush the third water treatment device 53. It can be understood that when the control valve 1 of the water treatment machine according to the embodiment of the utility model is controlled to be in the third positive flushing working position, the water treatment machine of the utility model is controlled to be in its third positive flushing working state.

[0112] It can be understood that the positive 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 utility model when the water flow flushes the water treatment device of the water treatment machine of the utility model, and the flow direction of the raw water flowing through the water treatment device of the water treatment machine of the utility model is the same as the flow direction of the raw water flowing through the water treatment device of the water treatment machine of the utility model when the water treatment device of the water treatment machine of the utility model treats the raw water. Generally, the time for forward flushing of the water treatment device of the water treatment machine of the utility model by 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 utility model. In addition, if the filter material (or softening material) of the water treatment device of the water treatment machine of the utility model is a granular filter material, the positive flushing can also play a role in compacting the filter material (or softening material) so that it has a better water treatment effect.

[0113] As shown in the attached picture FIG. 11A to FIG. 18G As shown, the control valve 1 of the water treatment machine according to the embodiment of the utility model is configured to be able to, more specifically, the control valve 1 of a single water treatment machine of the utility model is configured to be able to control the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 of the water treatment machine of the utility model to be connected in series and perform three-stage treatment on the raw water, and control the raw water to respectively and individually perform backwashing and forward flushing on the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 of the water treatment machine of the utility model.

Preferably, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes. Preferably, the eleventh channel 1011 is a conducting through hole. Preferably, the eighth channel 108 is connected to the valve cavity 110 and further connected to the second fluid opening 1108 through the valve cavity 110.

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, flows through the second fluid opening 1108 of the plane valve 1, the eighth channel 108, the first channel 101, the first opening 1101, the first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second opening 1102 of the plane valve 1, the second channel 102, the ninth channel 109, the third channel 103, the third opening 1103, the second water The second water inlet 521 of the treatment device 52, the second water outlet 522 of the second water treatment device 52, the fourth opening 1104 of the plane valve 1, the fourth channel 104, the tenth channel 1010, the fifth channel 105, the fifth opening 1105, the third water inlet 531 of the third water treatment device 53, the third water outlet 532 of the third water treatment device 53, the sixth opening 1106 of the plane valve 1, the sixth channel 106, the eleventh channel 1011, the seventh channel 107 and the first fluid opening 1107.

[0116] As shown in the attached picture 7A to 7I , Fig. 10A , Fig. 10B and Fig.18AAs shown, when the planar valve 1 is in the water treatment working position, the twelfth channel 1012 is blocked by the third fluid control surface 1223 of the movable valve plate 122 . It is worth noting that when the plane valve 1 is in the water treatment working position, the ninth channel 109 is connected to the second channel 102 and the third channel 103 respectively, the tenth channel 1010 is connected to the fourth channel 104 and the fifth channel 105 respectively, and the eleventh channel 1011 is connected to the sixth channel 106 and the seventh channel 107 respectively. That is to say, when the plane valve 1 is in the water treatment working position, the second opening 1102 and the third opening 1103 are connected through the second water treatment flow channel 7002, and the fourth opening 1104 and the fifth opening 1105 are connected through the third water treatment flow channel 7003, because the first opening 1101 is connected to the first water inlet 511 of the first water treatment device 51, the second opening 1102 is connected to the first water outlet 512 of the first water treatment device 51, and the third opening 1103 is connected to the second water treatment flow channel 7003. The second water inlet 521 of the device 52 is connected, the fourth opening 1104 is connected to the second water outlet 522 of the second water treatment device 52, the fifth opening 1105 is connected to the third water inlet 531 of the third water treatment device 53, and the sixth opening 1106 is connected to the third water outlet 532 of the third water treatment device 53. Therefore, when the plane valve 1 is in the water treatment working position, the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 form a three-stage series structure, and 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 will sequentially treat the raw water entering the second fluid opening 1108 of the plane valve 1, and the purified treated water flows out from the first fluid opening 1107 and is provided. The three-stage series structure can better perform deep treatment on raw water. Preferably, 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 as different filter materials.

It can be understood that the first water treatment device 51 can also be set as an aeration tank, the second water treatment material 525 can be set as a filter material for removing iron and manganese such as manganese sand, and the third water treatment material 535 can be set with a softening resin for softening treatment.

[0117] As shown in the attached picture FIG. 11A to FIG. 11Cand Fig.18A As shown, illustratively, when the plane valve 1 of the water treatment machine according to the 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 1108 of the valve body 10 under the action of water pressure, and then flows into the first opening 1101 through the eighth channel 108 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, and is treated by the first water treatment material 51 under the action of water pressure. After the primary treated water is treated (e.g., purified or softened), it is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51. Under the action of water pressure, the primary treated water further flows through the second opening 1102 of the plane valve 1, the second channel 102, the ninth channel 109, the third channel 103, and the third opening 1103 to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52. Under the action of water pressure, the primary treated water flows into the second water inlet 521 of the second water treatment device 52. After being treated by the second water treatment material 525 (for example, purified or softened), the generated secondary treated water is collected by the second central tube 524 and flows out from the second water outlet 522 of the second water treatment device 52; under the action of water pressure, the secondary treated water further flows through the fourth opening 1104 of the plane valve 1, the fourth channel 104, the tenth channel 1010, the fifth channel 105, the fifth opening 1105 to the third water inlet 531 of the third water treatment device 53 and flows into the The third water treatment device 53 is treated by the third water treatment material 535 (for example, purification or softening) under the action of water pressure, 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 sixth opening 1106 of the first valve body portion 11 of the planar valve 1, and then is provided through the sixth channel 106, the eleventh channel 1011, the seventh channel 107 and the first fluid opening 1107 of the planar valve 1.

[0118] As shown in the attached picture Fig. 10C , Fig. 10D , Fig.12 and Fig.18BAs shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model further has a first backwashing working position, wherein when the plane valve 1 is in the first backwashing working position, the eighth channel 108 of the plane valve 1 is connected with the second channel 102, thereby forming the first backwashing flow channel 7101 respectively connected with the second fluid opening 1108 and the second opening 1102 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the first channel 101, thereby forming the second backwashing flow channel 7102 respectively connected with the sewage opening 11012 and the first opening 1101 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Fig. 10C , Fig. 10D and Fig.18BAs shown, further, when the planar valve 1 is in the first backwash working position, the ninth channel 109 is respectively connected to the first channel 101 and the fourth channel 104, the tenth channel 1010 is connected to the third channel 103, the fifth channel 105 and the sixth channel 106 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, although the ninth channel 109 is connected to the first channel 101 and the fourth channel 104 respectively, and the tenth channel 1010 is connected to the third channel 103, since the fifth channel 105 and the sixth channel 106 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, and the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, the raw water can only flow into the eighth channel 108 from the second fluid opening 1108 of the plane valve 1, and further flow into the eighth channel 108 through the second fluid opening 1108 of the plane valve 1. The waste water generated by the second channel 102, the second opening 1102, the first water outlet 512 flowing to the first water treatment device 51 and the first water treatment device 51, and the waste water generated by the reverse flushing of 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 eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 is connected to the first channel 101 and the fourth channel 104 respectively, and the tenth channel 1010 is connected to the third channel 103, the water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the first backwash working position, the fifth channel 105 and the sixth channel 106 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing into the fifth opening 1105 and the sixth opening 1106 of the planar valve 1, so that no water flows in the third water treatment device 53; although the ninth channel 109 is respectively connected to the first channel 101 and the fourth channel 104, and the tenth channel 1010 is connected to the third channel 103, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, so the water is prevented from flowing through the third opening 1103 and the fourth opening 1104 of the planar valve 1, thereby preventing the flow of water in the second water treatment device 52.In other words, although the ninth channel 109 is respectively connected with the first channel 101 and the fourth channel 104, so that the first channel 101, the ninth channel 109, the fourth channel 104, the fourth opening 1104, the second water treatment device 52, the third opening 1103, the third channel 103 and the tenth channel 1010 of the planar valve 1 are connected in sequence, the tenth channel 1010 is a conductive blind hole, so that water cannot flow to the fourth channel 104 and the third channel 103, and the movable valve plate 122 blocks the water from flowing to the fifth channel 105 and the sixth channel 106, thereby ensuring that only the first water treatment device 51 is reverse flushed.

[0119] It is worth noting that when the plane valve 1 is in the first backwashing working position, the fifth channel 105 and the sixth channel 106 are blocked by the movable valve plate 122, so that the fifth opening 1105 and the sixth opening 1106 are blocked. Even if the ninth channel 109 is connected to the first channel 101 and the fourth channel 104, respectively, and the tenth channel 1010 is connected to the third channel 103, there is no water flow in the third opening 1103 and the fourth opening 1104, that is, there is no water flow in the second water treatment device 52, and the third water treatment device 53 is isolated from the water flow to ensure that only the first water treatment device 51 is backwashed, thereby increasing the strength 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 and / or the third water treatment device 53. 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.

[0120] 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 an 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 11012 through the second backwash channel 7102 and is discharged.

[0121] As shown in the attached picture Fig.10E , Fig.10F , Fig.13 and Fig.18CAs shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model further has a second backwashing working position, wherein when the plane valve 1 is in the second backwashing working position, the eighth channel 108 of the plane valve 1 is connected with the fourth channel 104, thereby forming the third backwashing flow channel 7103 respectively connected with the second fluid opening 1108 and the fourth opening 1104 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the third channel 103, thereby forming the fourth backwashing flow channel 7104 respectively connected with the sewage opening 11012 and the third opening 1103 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Fig.10E , Fig.10F and Fig.18CAs shown, further, when the planar valve 1 is in the second backwash working position, the ninth channel 109 is connected to the third channel 103, the tenth channel 1010 is connected to the sixth channel 106, the first channel 101, the second channel 102 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, although the ninth channel 109 is connected with the third channel 103, and the tenth channel 1010 is connected with the sixth channel 106, since the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, the raw water can only flow into the eighth channel 108 from the second fluid opening 1108 of the plane valve 1, and further flow through the fourth channel 104, the fourth opening 1104, flow to 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 third opening 1103 of the plane valve 1, and is further discharged through the third channel 103, the eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 is connected to the third channel 103 and the tenth channel 1010 is connected to the sixth channel 106, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1 is in the second backwashing working position, the first channel 101, the second channel 102 and the fifth channel 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, thereby preventing the water from flowing through the first opening 1101, the second opening 1102 and the fifth opening 1105 of the plane valve 1; although the tenth channel 1010 is connected to the sixth channel 106, the tenth channel 1010 is a conducting blind hole, so the water is prevented from flowing through the sixth opening 1106 of the plane valve 1, thereby preventing the water in the first water treatment device 51 and the third water treatment device 53 from flowing. In other words, although the tenth channel 1010 is connected with the sixth channel 106, so that the tenth channel 1010, the sixth channel 106, the sixth opening 1106, the third water treatment device 53, the fifth opening 1105, and the fifth channel 105 of the plane valve 1 are connected in sequence, the movable valve plate 122 blocks the raw water from flowing to the first channel 101, the second channel 102, the fifth channel 105 and the sixth channel 106, thereby ensuring that only the second water treatment device 52 is reverse flushed.

[0122] It is worth noting that when the plane valve 1 is in the second backwashing working position, the first channel 101, the second channel 102, the fifth channel 105 and the sixth channel 106 (or the flow channel formed by the tenth channel 1010 and the sixth channel 106) are blocked by the movable valve plate 122, so that the first opening 1101, the second opening 1102, the fifth opening 1105 and the sixth opening 1106 are blocked, so that the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow 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 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 utility model is backwashed separately.

[0123] 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 an 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 third opening 1103 of the plane valve 1, and then flows to the sewage opening 11012 through the fourth backwash channel 7104 and is discharged.

[0124] As shown in the attached picture Figure 10G , Fig. 10H , Fig.14 and Fig.18D As shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model further has a third backwashing working position, wherein when the plane valve 1 is in the third backwashing working position, the eighth channel 108 of the plane valve 1 is connected with the sixth channel 106, thereby forming the fifth backwashing flow channel 7105 respectively connected with the second fluid opening 1108 and the sixth opening 1106 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the fifth channel 105, thereby forming the sixth backwashing flow channel 7106 respectively connected with the sewage opening 11012 and the fifth opening 1105 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Figure 10G , Fig. 10H and Fig.18DAs shown, further, when the planar valve 1 is in the third backwash working position, the ninth channel 109 is connected to the first channel 101, the tenth channel 1010 is connected to the third channel 103, the second channel 102 and the fourth channel 104 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, although the ninth channel 109 is connected to the first channel 101 and the tenth channel 1010 is connected to the third channel 103, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, so that the raw water can only flow into the eighth channel 108 from the second fluid opening 1108 of the plane valve 1, and further flow through the sixth channel 106, the sixth opening 1106, flow to the third water outlet 532 of the third water treatment device 53 and flow into the third water treatment device 53. The waste water 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 fifth opening 1105 of the plane valve 1, and is further discharged through the fifth channel 105, the eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 of the planar valve 1 is connected to the first channel 101 and the tenth channel 1010 is connected to the third channel 103, water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the third backwash working position, the second channel 102 and the fourth channel 104 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the second opening 1102 and the fourth opening 1104 of the planar valve 1; although the ninth channel 109 is connected to the first channel 101 and the tenth channel 1010 is connected to the third channel 103, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, so the water flow is prevented from flowing through the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 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.In other words, although the ninth channel 109 is connected to the first channel 101, and the tenth channel 1010 is connected to the third channel 103, the ninth channel 109, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102, and the second channel 102 of the plane valve 1 are connected in sequence; the tenth channel 1010, the third channel 103, the third opening 1103, the second water treatment device 52, the fourth opening 1104, and the fourth channel 104 of the plane valve 1 are connected in sequence, but because the movable valve plate 122 blocks the raw water from flowing to the first channel 101, the second channel 102, the third channel 103 and the fourth channel 104, it is ensured that only the third water treatment device 53 is backwashed.

[0125] It is worth noting that when the planar valve 1 is in the third backwash working position, the first channel 101 (or the flow channel formed by the ninth channel 109 being connected to the first channel 101), the second channel 102, the third channel 103 (or the flow channel formed by the tenth channel 1010 being connected to the third channel 103) and the fourth channel 104 are respectively blocked by the movable valve plate 122, so that the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104 are blocked, so that 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 backwashed, thereby increasing the intensity of the water flow of the raw water for backwashing the third water treatment device 53, and preventing the generated sewage from flowing to 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 utility model is backwashed separately.

[0126] As shown in the attached picture Fig.14 and Fig.18D As shown, exemplarily, when the plane valve 1 of the water treatment machine according to an embodiment of the 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, and 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 fifth opening 1105 of the plane valve 1, and then flows to the sewage opening 11012 through the sixth backwash channel 7106 and is discharged.

[0127] 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 embodiment of the utility model further has a first positive flushing working position, wherein when the plane valve 1 is in the first positive flushing working position, the eighth channel 108 of the plane valve 1 is connected with the first channel 101, thereby forming the first positive flushing flow channel 7201 respectively connected with the second fluid opening 1108 and the first opening 1101 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the second channel 102, thereby forming the second positive flushing flow channel 7202 respectively connected with the sewage opening 11012 and the second opening 1102 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Fig.10I , Fig.10J and Fig.18EAs shown, further, when the planar valve 1 is in the first positive flushing working position, the ninth channel 109 is connected with the third channel 103, the tenth channel 1010 is respectively connected with the fifth channel 105 and the sixth channel 106, the fourth channel 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 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 positive flushing working position, although the ninth channel 109 of the plane valve 1 is connected to the third channel 103, and the tenth channel 1010 is connected to the fifth channel 105 and the sixth channel 106 respectively, since the fourth channel 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, the raw water can only flow into the eighth channel 108 from the second fluid opening 1108 of the plane valve 1. , and further through the first channel 101, the first opening 1101, the first water inlet 511 of the first water treatment device 51 and 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 eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 of the plane valve 1 is connected to the third channel 103, and the tenth channel 1010 is respectively connected to the fifth channel 105 and the sixth channel 106, the water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the first positive flushing working position, the fourth channel 104 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the fourth opening 1104 of the planar valve 1; although the ninth channel 109 is connected to the third channel 103, and the tenth channel 1010 is respectively connected to the fifth channel 105 and the sixth channel 106, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, and therefore, water is prevented from flowing through the third opening 1103, the fifth opening 1105 and the sixth opening 1106 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 ninth channel 109 is connected with the third channel 103, the tenth channel 1010 is respectively connected with the fifth channel 105 and the sixth channel 106, so that the ninth channel 109, the third channel 103, the third opening 1103, the second water treatment device 52, the fourth opening 1104, and the fourth channel 104 of the plane valve 1 are connected in sequence; the tenth channel 1010, the fifth channel 105, the fifth opening 1105, the third water treatment device 53, the sixth opening 1106, the sixth channel 106 and the tenth channel 1010 of the plane valve 1 are connected in sequence, but because the movable valve plate 122 blocks the raw water from flowing to the third channel 103, the fourth channel 104, the fifth channel 105 and the sixth channel 106, it is ensured that only the first water treatment device 51 is flushed forward.

[0128] It is worth noting that when the planar valve 1 is in the first positive flushing working position, the third channel 103 (or the flow channel formed by the ninth channel 109 being connected to the third channel 103) and the fourth channel 104 are respectively blocked by the movable valve plate 122, so that the third opening 1103 and the fourth opening 1104 are blocked, even if the tenth channel 1010 is respectively connected to the fifth channel 105 and the sixth channel 106, so that the fifth opening 1105 and the sixth opening 1106 are connected, but there is no water flow in the fifth opening 1105 and the sixth opening 1106, that is, the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow 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 positively flushing the first water treatment device 51, and preventing the generated sewage from flowing to 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 utility model is positively flushed alone.

[0129] As shown in the attached picture Fig.15 and Fig.18E As shown, exemplarily, when the plane valve 1 of the water treatment machine according to an 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 11012 through the second positive flushing channel 7202 and is discharged.

[0130] 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 embodiment of the utility model further has a second positive flushing working position, wherein when the plane valve 1 is in the second positive flushing working position, the eighth channel 108 of the plane valve 1 is connected with the third channel 103, thereby forming the third positive flushing flow channel 7203 respectively connected with the second fluid opening 1108 and the third opening 1103 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the fourth channel 104, thereby forming the fourth positive flushing flow channel 7204 respectively connected with the sewage opening 11012 and the fourth opening 1104 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Figure 10K , Fig.10L and Fig.18FAs shown, further, when the planar valve 1 is in the second positive flushing working position, the ninth channel 109 is respectively connected with the fifth channel 105 and the sixth channel 106, the tenth channel 1010 is respectively connected with the first channel 101 and the fifth channel 105, the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 is in the second positive flushing working position, although the ninth channel 109 of the plane valve 1 is connected to the fifth channel 105 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fifth channel 105 respectively, because the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, the raw water can only flow into the eighth channel from the second fluid opening 1108 of the plane valve 1. The waste water generated by the forward flushing of the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the plane valve 1, and is further discharged through the fourth channel 104, the eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 is connected to the fifth channel 105 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fifth channel 105 respectively, the water does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the second positive flushing working position, the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, thereby preventing water from flowing through the second opening 1102 of the planar valve 1; although the ninth channel 109 is respectively connected to the fifth channel 105 and the sixth channel 106, and the tenth channel 1010 is respectively connected to the first channel 101 and the fifth channel 105, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, and therefore, water is prevented from flowing through the first opening 1101, the fifth opening 1105 and the sixth opening 1106 of the planar valve 1, thereby preventing the flow of water in the first water treatment device 51 and the third water treatment device 53.In other words, although the ninth channel 109 is respectively connected to the fifth channel 105 and the sixth channel 106, and the tenth channel 1010 is respectively connected to the first channel 101 and the fifth channel 105, so that the ninth channel 109, the sixth channel 106, the sixth opening 1106, the third water treatment device 53, the fifth opening 1105, the fifth channel 105 (the ninth channel 109), the tenth channel 1010, the first channel 101, the first opening 1101, the first water treatment device 51, the second opening 1102, and the second channel 102 of the plane valve 1 are connected in sequence, but the movable valve plate 122 blocks the raw water from flowing to the first channel 101, the second channel 102, the fifth channel 105 and the sixth channel 106, thereby ensuring that only the second water treatment device 52 is flushed forward.

[0131] It is worth noting that when the planar valve 1 is in the second positive flushing working position, the second channel 102 is blocked by the movable valve plate 122, so that the second opening 1102 is blocked, even if the ninth channel 109 is respectively connected to the fifth channel 105 and the sixth channel 106, and the tenth channel 1010 is respectively connected to the first channel 101 and the fifth channel 105, so that the first opening 1101, the fifth opening 1105 and the sixth opening 1106 are connected, but there is no water flow in the first opening 1101, the fifth opening 1105 and the sixth opening 1106, that is, the first water treatment device 51 and the third water treatment device 53 are isolated from the water flow 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 positively flushing the second water treatment device 52, and preventing the generated sewage from flowing to 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 utility model is positively flushed alone.

[0132] As shown in the attached picture Fig.16 and Fig.18F As shown, exemplarily, when the plane valve 1 of the water treatment machine according to an 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 fourth opening 1104 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11012 through the fourth positive flushing channel 7204 and is discharged.

[0133] 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 embodiment of the utility model further has a third positive flushing working position, wherein when the plane valve 1 is in the third positive flushing working position, the eighth channel 108 of the plane valve 1 is connected with the fifth channel 105, thereby forming the fifth positive flushing flow channel 7205 respectively connected with the second fluid opening 1108 and the fifth opening 1105 of the plane valve 1, and the eleventh channel 1011 is respectively connected with the twelfth channel 1012 and the sixth channel 106, thereby forming the sixth positive flushing flow channel 7206 respectively connected with the sewage opening 11012 and the sixth opening 1106 of the plane valve 1. As shown in the accompanying drawings 7A to 7I , Figure 10M , Fig.10N and Figure 18GAs shown, further, when the planar valve 1 is in the third positive flushing working position, the ninth channel 109 is respectively connected to the second channel 102 and the sixth channel 106, the tenth channel 1010 is respectively connected to the first channel 101 and the fourth channel 104, the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the seventh channel 107 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Therefore, when the plane valve 1 is in the third positive flushing working position, although the ninth channel 109 is connected to the second channel 102 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fourth channel 104 respectively, because the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, the raw water can only flow into the eighth channel from the second fluid opening 1108 of the plane valve 1. 108, and further flows to the third water inlet 531 of the third water treatment device 53 and flows into the third water treatment device 53 through the fifth channel 105 and the fifth opening 1105, and the waste water generated by positively flushing the third water treatment device 53 flows from the third water outlet 532 of the third water treatment device 53 to the sixth opening 1106 of the plane valve 1, and is further discharged through the sixth channel 106, the eleventh channel 1011, the twelfth channel 1012 and the sewage opening 11012 of the plane valve 1 under the action of water pressure. In other words, although the ninth channel 109 is respectively connected to the second channel 102 and the sixth channel 106, and the tenth channel 1010 is respectively connected to the first channel 101 and the fourth channel 104, the water flow does not flow through the flow channel formed by them. Correspondingly, when the planar valve 1 is in the third 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 planar valve 1; although the ninth channel 109 is respectively connected to the second channel 102 and the sixth channel 106, and the tenth channel 1010 is respectively connected to the first channel 101 and the fourth channel 104, the ninth channel 109 and the tenth channel 1010 are both conducting blind holes, and the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122. Therefore, no water flows through the first opening 1101, the second opening 1102 and the fourth opening 1104 of the planar valve 1, so that no water flows in the first water treatment device 51 and the second water treatment device 52.In other words, although the ninth channel 109 is connected to the second channel 102 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fourth channel 104 respectively, so that the sixth channel 106, the ninth channel 109, the second channel 102, the second opening 1102, the first water treatment device 51, the first opening 1101, the first channel 101, the tenth channel 1010, the fourth channel 104, the fourth opening 1104, the second water treatment device 52, the third opening 1103 and the third channel 103 of the plane valve 1 are connected in sequence, but because the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, There is no water flowing in the flow channels connected in sequence among the sixth channel 106, the ninth channel 109, the second channel 102, the second opening 1102, the first water treatment device 51, the first opening 1101, the first channel 101, the tenth channel 1010, the fourth channel 104, the fourth opening 1104, the second water treatment device 52, the third opening 1103 and the third channel 103, that is, there is no water flowing in the first water treatment device 51 and the second water treatment device 52. At the same time, the movable valve plate 122 blocks the raw water from flowing to the first channel 101, the second channel 102, the third channel 103 and the fourth channel 104, thereby ensuring that only the third water treatment device 53 is flushed forward.

[0134] 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 ninth channel 109 is connected to the second channel 102 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fourth channel 104 respectively, so that the sixth opening 1106 is connected to the second opening 1102, and the first opening 1101 is connected to the fourth opening 1104, but the ninth channel 109 is connected to the second channel 102 and the sixth channel 106 respectively, and the tenth channel 1010 is connected to the first channel 101 and the fourth channel 104 respectively, so that the sixth opening 1106 is connected to the second opening 1102, and the first opening 1101 is connected to the fourth opening 1104. The three openings 1103 are blocked, so that no water flows in the first opening 1101, the second opening 1102, the third opening 1103 and the fourth opening 1104, that is, no water flows in the first water treatment device 51 and the second water treatment device 52, so as to ensure that only the third water treatment device 53 is forward flushed, thereby increasing the strength of the water flow of the raw water for forward flushing the third water treatment device 53, and preventing the generated sewage from flowing to the first water treatment device 51 and / or the second water treatment device 52. Therefore, when the plane valve 1 is in the third forward flushing working position, the third water treatment device 53 of the water treatment machine of the utility model is forward flushed alone.

[0135] As shown in the attached picture Fig.17 and Figure 18GAs shown, exemplarily, when the plane valve 1 of the water treatment machine according to an embodiment of the 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, and 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 sixth opening 1106 of the plane valve 1 under the action of water pressure, and then flows to the sewage opening 11012 through the sixth positive flushing channel 7206 and is discharged.

[0136] It is worth noting that the traditional plane valve adopts a valve core structure with a single moving valve plate and a single fixed valve plate, and its moving valve plate often requires at least one conducting blind hole to guide the water flow to the outlet. When the water flows in the guide blind hole, the flow direction changes 360 degrees, which will cause the water flow to encounter 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 flows upward from the lower valve plate (the first fixed valve plate 121), and the outlet is on the upper valve plate (the second fixed valve plate 123). The change in the flow direction of the water flow is small, 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.

It is worth noting that the first fixed valve plate 121 of the planar valve 1 can be detachably set on the first inner wall 111 of the first valve body portion 11, or it can be integrally formed with the first inner wall 111 of the first valve body portion 11 of the planar valve 1; the second fixed valve plate 123 of the planar valve 1 can be detachably set on the second inner wall 131 of the second valve body portion 13, or it can be integrally formed with the second inner wall 131 of the second valve body portion 13 of the planar valve 1.

For example, the driving element 17 can be a valve stem, a driving gear or a driving gear set. For example, the driving element of the water treatment machine of the utility model can be a driving shaft, which passes through the second fixed valve disc 123 and enters the central part of the movable valve disc 122, and the driving shaft is configured to drive the movable valve disc 122 to rotate while not driving the second fixed valve disc 123 to rotate.

[0153] As shown in the attached picture FIG. 6C to FIG. 6N , Figure 6P , Figure 6Q and FIG. 11A to FIG. 17 As shown, the diameter of the movable valve plate 122 of the planar valve 1 is set to be slightly smaller than the diameter of the valve cavity 110 of the valve body 10, so that the eighth channel 108 of the planar valve 1 can remain connected to the valve cavity 110 of the valve body 10.
