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 users. Finally, generally speaking, the control valve of the water treatment machine adopts a traditional double valve plate structure, and at least one diversion blind hole needs to be set in the moving valve plate to provide treated water so that the flow direction of the water can be changed. However, when the water flows in the diversion 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, resulting in a significant reduction in the flow rate of the water flow.

Accordingly, the water treatment machine of the utility model and the control valve used 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 difficult problem of using a single control valve to perform reverse or forward flushing on three water treatment devices used in series separately and individually.

[0109] As shown in the attached picture Fig.15 and Fig.18EAs shown, the control valve 1 of the water treatment machine according to the embodiment of the utility model has a first positive flushing working position, wherein when the control valve 1 of the water treatment machine of the utility model is in the first positive flushing working position, the valve core 12 of the control valve 1 forms a first positive flushing flow channel 7201 and a second positive flushing flow channel 7202, wherein the first positive flushing flow channel 7201 is respectively connected to the second fluid opening 1107 and the first opening 1101, and the second positive flushing flow channel 7202 is respectively connected to the sewage opening 11010 and the second opening 1102. Accordingly, when the control valve 1 of the water treatment machine of the present invention is in the first positive flushing working position, raw water flows in from the second fluid opening 1107 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. The sewage after positive flushing the first water treatment device 51 flows out from the first water outlet 512, and then is discharged through the second opening 1102, the second positive flushing channel 7202 and the sewage discharge opening 11010. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the present invention is configured to prevent raw water from flowing from the second fluid opening 1107 of the valve body 10 of the control valve 1 to the third opening 1103, the fourth opening 1104 and the fifth opening 1105 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 and the fifth opening 1105 is blocked, so that the flow of water in the second water treatment device 52 and the third water treatment device 53 is blocked. 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, the water flow cannot flow from the second opening 1102 or the third opening 1103 of the first valve body 11 to the second water treatment device 52; the water flow cannot flow from the fourth opening 1104 or the fifth opening 1105 of the first valve body 11 to the third water treatment device 53, and the water flow cannot flow from the first water outlet 512 of the first water treatment device 51 to the second water inlet 521 of the second water treatment device 52, thereby ensuring that the 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 position, the water treatment machine of the utility model is controlled to be in its first positive flushing working state to positively flush the first water treatment device 51 of the water treatment machine of the utility model.

[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 of the water treatment machine of the utility model is in the second positive flushing working position, the valve core 12 of the control valve 1 forms a third positive flushing flow channel 7203 and a fourth positive flushing flow channel 7204, wherein the third positive flushing flow channel 7203 is respectively connected to the second fluid opening 1107 and the second opening 1102, and the fourth positive flushing flow channel 7204 is respectively connected to the sewage opening 11010 and the third opening 1103. Accordingly, when the control valve 1 of the water treatment machine of the present invention is in the second positive flushing working position, raw water flows in from the second fluid opening 1107 of the valve body 10 of the control valve 1 under the action of water pressure, flows to the second opening 1102 through the third positive flushing flow channel 7203, and further flows into the second water treatment device 52 from the second water inlet 521. The sewage after positive flushing the second water treatment device 52 flows out from the second water outlet 522, and then is discharged through the third opening 1103, the fourth positive flushing flow channel 7204 and the sewage discharge opening 11010. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the present invention is configured to prevent raw water from flowing from the second fluid opening 1107 of the valve body 10 of the control valve 1 to the first opening 1101, the fourth opening 1104 and the fifth opening 1105 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 present invention is controlled to be in the second positive flushing working position, the flow of water in the first opening 1101, the fourth opening 1104 and the fifth opening 1105 is blocked, so that the flow of water in the first water treatment device 51 and the third water treatment device 53 is blocked. More specifically, when the control valve 1 of the water treatment machine according to the embodiment of the present invention is controlled to be in the second positive flushing working position, the water flow 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; the water flow cannot flow from the fourth opening 1104 and the fifth opening 1105 of the first valve body 11 to the third water treatment device 53, and the water flow cannot flow 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, thereby ensuring that the 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 position, the water treatment machine of the utility model is controlled to be in its second positive flushing working state to positively flush the second water treatment device 52 of the water treatment machine of the utility model.

[0111] As shown in the attached picture Fig.17 and Figure 18GAs shown, the control valve 1 of the water treatment machine according to the embodiment of the utility model has a third positive flushing working position, wherein when the control valve 1 of the water treatment machine of the utility model is in the third positive flushing working position, the valve core 12 of the control valve 1 forms a fifth positive flushing channel 7205 and a sixth positive flushing channel 7206, wherein the fifth positive flushing channel 7205 is respectively connected to the second fluid opening 1107 and the fourth opening 1104, and the sixth positive flushing channel 7206 is respectively connected to the sewage opening 11010 and the fifth opening 1105. Accordingly, when the control valve 1 of the water treatment machine of the present invention is in the third positive flushing working position, raw water flows in from the second fluid opening 1107 of the valve body 10 of the control valve 1 under the action of water pressure, flows to the fourth opening 1104 through the fifth positive flushing flow channel 7205, and further flows into the third water treatment device 53 from the third water inlet 531. The sewage after positive flushing the third water treatment device 53 flows out from the third water outlet 532, and then is discharged through the fifth opening 1105, the sixth positive flushing flow channel 7206 and the sewage discharge opening 11010. Preferably, the control valve 1 of the water treatment machine according to the embodiment of the present invention is configured to prevent raw water from flowing from the second fluid opening 1107 of the valve body 10 of the control valve 1 to the first opening 1101, the second opening 1102 and the third opening 1103 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 present 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 and the third opening 1103 is blocked, so that the flow of water in the first water treatment device 51 and the second water treatment device 52 is blocked. 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, the water flow 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; the water flow cannot flow from the second opening 1102 or the third opening 1103 of the first valve body 11 to the second water treatment device 52, thereby ensuring that the 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 to positively flush the third water treatment device 53 of the water treatment machine of the utility model.

[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 an embodiment of the utility model, more specifically, the control valve 1 of a single water treatment machine of the utility model, is configured 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 raw water, and control the raw water to respectively and individually perform reverse flushing 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.

[0114] As shown in the attached picture Figures 5 to 8CAs shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model has a first channel 101, a second channel 102, a third channel 103, a fourth channel 104, a fifth channel 105, a sixth channel 106, a seventh channel 107, an eighth channel 108, a ninth channel 109 and a tenth channel 1010, wherein the first channel 101, the second channel 102, the third channel 103, the fourth channel 104 and the fifth channel 105 are respectively arranged on the first fixed valve plate 121 and extend from the first fluid control surface 1210 of the first fixed valve plate 121; the seventh channel 107, the eighth channel 108 and the ninth channel 109 are respectively arranged on the movable valve plate 122, wherein the seventh channel 107 and the eighth channel 108 are respectively extended from the second fluid control surface 1210 of the movable valve plate 122 20 extends, the ninth channel 109 extends from the second fluid control surface 1220 of the movable valve disc 122 to the third fluid control surface 1223; the sixth channel 106 and the tenth channel 1010 are respectively arranged on the second fixed valve disc 123 and respectively extend from the fourth fluid control surface 1230 of the second fixed valve disc 123, wherein the first channel 101 is connected to the first opening 1101, the second channel 102 is connected to the second opening 1102, the third channel 103 is connected to the third opening 1103, the fourth channel 104 is connected to the fourth opening 1104, the fifth channel 105 is connected to the fifth opening 1105, the sixth channel 106 is connected to the first fluid opening 1106, the seventh channel 107 is connected to the second fluid opening 1107, and the tenth channel 1010 is connected to the sewage opening 11010. Preferably, the eighth channel 108 is a conducting blind hole. Preferably, the ninth channel 109 is a conducting through hole. Preferably, the seventh channel 107 is connected to the valve cavity 110 and further connected to the second fluid opening 1107 through the valve cavity 110 .

[0115] As shown in the attached picture Fig. 10A , Fig. 10B , Fig.11A , Fig. 11B and Fig.18AAs shown, according to the embodiment of the utility model, the movable valve plate 122 of the plane valve 1 of the water treatment machine can rotate relative to the first fixed valve plate 121 and the second fixed valve plate 123 so that the plane valve 1 has a water treatment working position. When the plane valve 1 of the water treatment machine of the utility model is in the water treatment working position, the seventh channel 107 of the plane valve 1 is connected with the first channel 101, thereby forming the second fluid opening 1107 and the first opening 1101 connected respectively. The first water treatment channel 7001, the eighth channel 108 is respectively connected to the third channel 103 and the fourth channel 104, thereby forming the second water treatment channel 7002 which is 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 which is respectively connected to the fifth opening 1105 and the first fluid opening 1106. 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 1107 of the plane valve 1, the seventh channel 107, the first channel 101, the first opening 1101, the first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second water inlet 521 of the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second water inlet 521 of ... first water inlet 511 of the first water treatment device 51, the first water outlet 512 of the first water treatment device 51, the second water inlet 521 of the second water treatment device 52, the second water treatment device 52, the second water treatment device 52, the first water inlet 511 of the first water treatment device 5 52, the second water outlet 522 of the plane valve 1, 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, 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 fifth opening 1105 of the plane valve 1, the fifth channel 105, the ninth channel 109, the sixth channel 106 and the first fluid opening 1106. As shown in the accompanying drawings 7A to 7I , Fig. 10A , Fig. 10B and Fig.18A As shown, exemplarily, when the planar valve 1 of the water treatment machine of the utility model is in the water treatment working position, the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122, and the tenth channel 1010 is blocked by the third fluid control surface 1223 of the movable valve plate 122.

[0116] It is worth noting that when the plane valve 1 of the water treatment machine of the present invention is in the water treatment working position, the eighth channel 108 is respectively connected to the third channel 103 and the fourth channel 104, and the ninth channel 109 is respectively connected to the fifth channel 105 and the sixth channel 106. 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, the third opening 1103 and the fourth opening 1104 are connected through the second water treatment flow channel 7002, 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 respectively connected to the first water outlet 512 of the first water treatment device 51 and the second water inlet 521 of the second water treatment device 52, the third opening 1103 is connected to the second water outlet 522 of the second water treatment device 52, and the fourth opening 1104 is connected to the third water outlet 521 of the third water treatment device 53. The water inlet 531 is connected, the fifth opening 1105 is connected to the third water outlet 532 of the third water treatment device 53, and the second channel 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122 to prevent the primary treated water from flowing from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the plane valve 1 and to the second channel 102, so that the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 form a series structure and the raw water is treated by the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 in turn. In other words, when the planar valve 1 of the water treatment machine of the utility model is in the water treatment working position, the second channel 102 of the planar valve 1 is blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the flow of water in the second opening 1102 of the first valve body 11 of the planar valve 1 is blocked; because the second opening 1102 of the first valve body 11 of the planar valve 1, 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 the three-way structure 61, and when the flow of water in the second opening 1102 of the first valve body 11 of the planar valve 1 is blocked, 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.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, ensuring that the water flows through the first water treatment device 51, the second water treatment device 52 and the third water treatment device 53 in sequence and that the raw water is sequentially treated by 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 (for example, coarse filtration, filtration and softening treatment are performed respectively), and the three-stage treated water produced after treatment flows out from the first fluid opening 1106 and is provided. The three-stage series structure of the water treatment machine of the utility model 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 are set as different filter materials. For example, the first water treatment material 515 can be set to quartz sand, which is used as a coarse filter material, the second water treatment material 525 can be set to granular activated carbon, which is used as an adsorption material, and the third water treatment material 535 can be set to PP cotton, which is used as a precision filter material. Optionally, the third water treatment material 535 is set to a softening resin for softening treatment. It can be understood that the first water treatment device 51 can also be set to an aeration tank, the second water treatment material 525 can be set to a filter material for removing iron and manganese such as manganese sand, and the third water treatment material 535 can be set to a softening resin for softening treatment.

[0117] As shown in the attached picture Fig.11A , Fig. 11B and Fig.18AAs shown, exemplarily, 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 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, and is treated by the first water treatment material 515 under the action of water pressure (for example, purification treatment or softening treatment). 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, and then flows 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, and then is treated by the second water treatment material 525 under the action of water pressure (for example, purification treatment or softening treatment). For example, after purification treatment or softening treatment), 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 to the third water inlet 531 of the third water treatment device 53 through the third opening 1103, the third channel 103, the eighth channel 108, the fourth channel 104, and the fourth opening 1104 of the plane valve 1 and flows into the third water treatment device 53. Under the action of water pressure, after being treated by the third water treatment material 535 (for example, purification treatment or softening treatment), the generated tertiary treated water is collected by the third central tube 534, and flows out from the third water outlet 532 of the third water treatment device 53 and flows to the fifth opening 1105, the fifth channel 105, the ninth channel 109, the sixth channel 106 of the plane valve 1 and is provided through the first fluid opening 1106.

[0118] As shown in the attached picture Fig. 10C , Fig. 10D , Fig.12 and Fig.18B As shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model further has a first backwashing working position. When the plane valve 1 is in the first backwashing working position, the seventh channel 107 of the plane valve 1 is connected with the second channel 102, thereby forming the first backwashing flow channel 7101 connected with the second fluid opening 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 backwashing flow channel 7102 connected with the sewage opening 11010 and the first opening 1101 respectively. As shown in the accompanying drawings 7A to 7I , Fig. 10C , Fig. 10D and Fig.18BAs shown, when the plane valve 1 is in the first backwashing working position, the eighth channel 108 of the plane valve 1 is connected with the fifth channel 105, the third channel 103 and the fourth channel 104 are 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 backwashing working position, although the eighth channel 108 of the plane valve 1 is connected with the fifth channel 105, and the eighth channel 108 is a conducting blind hole, the fifth channel 105 is blocked by the movable valve plate 122, and because the third channel 103 and the fourth channel 104 are blocked by the second fluid control surface 1220 of the movable valve plate 122, the raw water can only flow into the seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and further The waste water 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 waste water 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, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1 is in the first backwashing working position, the third channel 103 and the fourth channel 104 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, thereby preventing water from flowing through the third opening 1103 and the fourth opening 1104 of the plane valve 1; although the eighth channel 108 is connected to the fifth channel 105, the eighth channel 108 is a conducting blind hole, so the water is prevented from flowing through 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. More specifically, when the plane valve 1 is in the first backwashing working position, the flow of water from the second opening 1102 to the second water inlet 521 of the second water treatment device 52 can be prevented. In other words, although the eighth channel 108 is connected to the fifth channel 105, the movable valve plate 122 blocks the raw water from flowing to the third channel 103, the fourth channel 104 and the fifth channel 105, thereby ensuring that only the first water treatment device 51 is reversely flushed.

[0119] It is worth noting that when the plane valve 1 is in the first backwashing working position, the third channel 103, the fourth channel 104 and the fifth channel 105 (or the flow channel formed by the eighth channel 108 and the fifth channel 105) are all blocked by the movable valve plate 122, so that the third opening 1103, the fourth opening 1104 and the fifth opening 1105 are all blocked. Although the eighth channel 108 is connected to the fifth channel 105, water cannot flow from the eighth channel 108 and the fifth channel 105. 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 the water flow cannot flow to 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 intensity of the water flow of the raw water backwashing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52 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 11010 through the second backwash channel 7102 and is discharged.

[0121] As shown in the attached picture Fig. 10E , Fig.10F , Fig.13 and Fig. 18C As shown, the plane valve 1 of the water treatment machine according to the embodiment of the utility model further has a second backwashing working position. When the plane valve 1 is in the second backwashing working position, the seventh channel 107 of the plane valve 1 is connected with the third channel 103, thereby forming the third backwashing flow channel 7103 connected with the second fluid opening 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 backwashing flow channel 7104 connected with the sewage opening 11010 and the second opening 1102 respectively. As shown in the accompanying drawings 7A to 7I , Fig. 10E , Fig.10F and Fig. 18CAs shown, when the planar valve 1 is in the second backwash working position, the eighth channel 108 is connected to the second channel 102, the first channel 101, the fourth channel 104 and the fifth channel 105 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. Although the eighth channel 108 is connected with the second channel 102, since the eighth channel 108 is a conductive blind hole, and since the first channel 101, the fourth channel 104 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the raw water can only flow into the seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and further flow through the third channel 103, the third opening 1103, flow to the second water outlet 522 of the second water treatment device 52 and flow 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 connected to the second channel 102, since the eighth channel 108 is a conducting blind hole, the water does not flow through the flow channel formed by them. Therefore, when the planar valve 1 is in the second backwash working position, the first channel 101, the fourth channel 104 and the fifth channel 105 of the planar valve 1 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the flow of water in the first opening 1101, the fourth opening 1104 and the fifth opening 1105 of the first valve body 11 of the planar valve 1 is blocked, the flow of water from the second opening 1102 of the first valve body 11 of the planar valve 1 to the first water outlet 512 of the first water treatment device 51 is blocked, 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; and the flow of water in the first water treatment device 51 and the third water treatment device 53 is blocked. Correspondingly, 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, so as to increase the intensity of the water flow for backwashing the second water treatment device 52 while 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. In addition, when the raw water backwashes the second water treatment device 52, the sewage flow flowing out of the second water inlet 521 of the second water treatment device 52 and flowing to the second opening 1102 cannot flow to the first water outlet 512 of the first water treatment device 51, thereby ensuring the water flow intensity for backwashing the second water treatment device 52 and avoiding the sewage flow generated after backwashing the second water treatment device 52 from polluting the first water treatment device 51 and the third water treatment device 53.

[0122] It is worth noting that when the plane valve 1 is in the second backwashing working position, the first channel 101, the fourth channel 104 and the fifth channel 105 are blocked by the movable valve plate 122, so that the first opening 1101, the fourth opening 1104 and the fifth opening 1105 are all blocked. Even if the eighth channel 108 is connected to the second channel 102, there is no water flow in the first opening 1101, the fourth opening 1104 and the fifth opening 1105, and there is no water flow in the first water treatment device 51. The third water treatment device 53 is 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 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 second opening 1102 of the first valve body part 11 of the plane valve 1, and then flows to the sewage opening 11010 through the fourth backwash channel 7104 and is discharged.

[0124] As shown in the attached picture Figure 10G , Fig. 10H , Fig.14 and Fig.18DAs 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. When the plane valve 1 is in the third backwashing working position, the seventh channel 107 of the plane valve 1 is connected with the fifth channel 105, thereby forming the fifth backwashing flow channel 7105 connected with the second fluid opening 1107 and the fifth opening 1105 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the fourth channel 104 respectively, thereby forming the sixth backwashing flow channel 7106 connected with the sewage opening 11010 and the fourth opening 1104 respectively. As shown in the accompanying drawings 7A to 7I , Figure 10G , Fig. 10H and Fig.18DAs shown, when the planar valve 1 is in the third backwash working position, the eighth channel 108 of the planar valve 1 is connected to the second channel 102, the first channel 101 and the third channel 103 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. Although the eighth channel 108 is connected with the second channel 102, since the eighth channel 108 is a conductive blind hole, and since the first channel 101 and the third channel 103 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the raw water can only flow into the seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and further flow through the fifth channel 105 and the fifth opening 1105 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 fourth opening 1104 of the plane valve 1, and is further discharged through the fourth channel 104, 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 second channel 102, the eighth channel 108 is a conducting blind hole, so the second channel 102 is blocked by the movable valve plate 122, and the first channel 101 and the third channel 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that 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. 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, so as to increase the intensity of the water flow for backwashing the third water treatment device 53 while 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.

[0125] It is worth noting that when the planar valve 1 is in the third backwash working position, the first channel 101, the second channel 102 (or the flow channel formed by the eighth channel 108 being connected with 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 all blocked. Even if the eighth channel 108 is connected with the second channel 102, there is no water flow in the first opening 1101, the second opening 1102 and the third opening 1103, and 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 center 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 fourth opening 1104 of the first valve body part 11 of the plane valve 1, and then flows to the sewage opening 11010 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. When the plane valve 1 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 , Fig.10I and Fig.10JAs shown, when the plane valve 1 is in the first positive flushing working position, the eighth channel 108 of the plane valve 1 is connected to the first channel 101 and the fourth channel 104 respectively, the third channel 103 and the fifth channel 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122 respectively, and the sixth channel 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Fig.10I , Fig.10J and Fig.18EAs shown in FIG. 1 , 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 fourth channel 104 respectively, since the eighth channel 108 is a conducting blind hole, and the third channel 103 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the raw water can only flow into the seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and further flow into the seventh channel 107 through the first fluid opening 1107 of the plane valve 1. The channel 101 and the first opening 1101 flow toward the first water inlet 511 of the first water treatment device 51 and flow into the first water treatment device 51. The waste water generated by 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 fourth channel 104 respectively, since the eighth channel 108 is a conducting blind hole and the fifth channel 105 is blocked by the second fluid control surface 1220 of the movable valve plate 122, the water flows from the first channel 101 to the eighth channel 108, the fourth channel 104, the fourth opening 1104, the third water inlet 531 of the third water treatment device 53, the third water inlet 532 of the third water treatment device 53, the third water inlet 533 of the third water treatment device 53, the third water inlet 534 of the third water treatment device 53, the third water inlet 535 of the third water treatment device 53, the third water inlet 536 of the third water treatment device 53, the third water inlet 537 of the third water treatment device 53, the third water inlet 538 of the third water treatment device 53, the third water inlet 539 of the third water treatment device 53, the third water inlet 530 of the third water treatment device 53, the third water inlet 531 of the third water treatment device 53, the third water inlet 532 of the third water treatment device 53, the third water inlet 533 of the third water treatment device 53, the third water inlet 534 of the third water treatment device 53, the third water inlet 536 of the third water treatment device 53, the third water inlet 538 ... The flows of the three water treatment devices 53, the third water outlet 532 of the third water treatment device 53, the fifth opening 1105 and the fifth channel 105 are blocked; since the third channel 103 is blocked by the second fluid control surface 1220 of the movable valve plate 122, the waste water generated by forward flushing the first water treatment device 51 is blocked from flowing from the first water outlet 512 of the first water treatment device 51 to the second water inlet 521 of the second water treatment device 52. Correspondingly, when the planar valve 1 is in the first positive flushing working position, the third channel 103 and the fifth channel 105 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 and the fifth opening 1105 of the planar valve 1. Although the eighth channel 108 of the planar valve 1 is respectively connected to the first channel 101 and the fourth channel 104, since the eighth channel 108 is a conducting blind hole, water 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 fourth channel 104, since the eighth channel 108 is a conductive blind hole, and the third channel 103 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the movable valve plate 122 hinders the raw water from flowing to the third channel 103, the fourth channel 104 and the fifth channel 105, thereby ensuring that only the first water treatment device 51 is flushed in the forward direction.

[0128] It is worth noting that when the plane valve 1 is in the first positive flushing working position, the third channel 103 and the fifth channel 105 are blocked by the movable valve plate 122, so that the third opening 1103 and the fifth opening 1105 are blocked. Even if the eighth channel 108 is connected to the first channel 101 and the fourth channel 104, respectively, no water flows in the third opening 1103, the fourth opening 1104 and the fifth opening 1105, and water flows from the first water outlet 512 of the first water treatment device 51 to the second water treatment device 51. The flow of water from the second water inlet 521 of the water treatment device 52 is blocked, and the flow of water from the fourth opening 1104 to the third water inlet 531 of the third water treatment device 53 is blocked, that is, no water flows in the second water treatment device 52 and the third water treatment device 53, so as to ensure that only the first water treatment device 51 is positively flushed, thereby increasing the strength of the water flow of the raw water for positively flushing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52 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 11010 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.18FAs 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. When the plane valve 1 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 and Fig.10L As shown, when the plane valve 1 is in the second positive flushing working position, the eighth channel 108 of the plane valve 1 is connected to the first channel 101, the fourth channel 104 and the fifth channel 105 are 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. Figure 10K , Fig.10L and Fig.18FAs 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, the eighth channel 108 is a conducting blind hole, so the first channel 101 is blocked by the movable valve plate 122, and the fourth channel 104 and the fifth channel 105 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 into the The waste water 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 flows into the second water treatment device 52. The waste water generated by positively flushing the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the third opening 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, 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, the first channel 101, the fourth channel 104 and the fifth channel 105 are all blocked by the movable valve plate 122, thereby preventing water from flowing through the first opening 1101, the fourth opening 1104 and the fifth opening 1105 of the plane valve 1, so that the flushing water flowing from the second opening 1102 to the second water inlet 521 of the second water treatment device 52 is prevented from flowing to the first water outlet 512 of the first water treatment device 51. Although the eighth channel 108 of the plane valve 1 is connected to the first channel 101, since the eighth channel 108 is a conducting blind hole, and the fourth channel 104 and the fifth channel 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, the water flow is blocked from flowing through the first opening 1101, the fourth opening 1104 and the fifth opening 1105 of the plane valve 1, thereby blocking the flow of water in the first water treatment device 51 and the third water treatment device 53. In other words, the first channel 101, the fourth channel 104 and the fifth channel 105 are all blocked by the movable valve plate 122, so the movable valve plate 122 hinders the water flow to the first channel 101, the fourth channel 104 and the fifth channel 105, thereby ensuring that only the second water treatment device 52 is forwardly flushed.

[0131] It is worth noting that when the plane valve 1 is in the second positive flushing working position, the first channel 101 (or the flow channel formed by the eighth channel 108 connected to the first channel 101), the fourth channel 104 and the fifth channel 105 are blocked by the movable valve plate 122, so that the first opening 1101, the fourth opening 1104 and the fifth opening 1105 are blocked, that is, no water flows in the first water treatment device 51, and the third water treatment device 53 is 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 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.

[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. When the plane valve 1 is in the third positive flushing working position, the seventh channel 107 of the plane valve 1 is connected with the fourth channel 104, thereby forming the fifth positive flushing flow channel 7205 connected with the second fluid opening 1107 and the fourth opening 1104 respectively, and the ninth channel 109 is connected with the tenth channel 1010 and the fifth channel 105 respectively, thereby forming the sixth positive flushing flow channel 7206 connected with the sewage opening 11010 and the fifth opening 1105 respectively. As shown in the accompanying drawings 7A to 7I , Figure 10M and Fig.10NAs shown, when the plane valve 1 is in the third positive flushing working position, the eighth channel 108 of the plane valve 1 is connected to the third channel 103, the first channel 101 and the second channel 102 are 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. Figure 10M , Fig.10N and Figure 18G As shown, specifically, when the plane valve 1 is in the third positive flushing working position, although the eighth channel 108 of the plane valve 1 is connected to the third channel 103, the eighth channel 108 is a conducting blind hole, so the third channel 103 is blocked by the movable valve plate 122, and the first channel 101 and the second channel 102 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, so that the raw water can only flow into the seventh channel 107 from the second fluid opening 1107 of the plane valve 1, and into the The waste water flows through the fourth channel 104 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 waste water 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 fifth channel 105, 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 third channel 103, the water does not flow through the flow channel formed by them. Accordingly, when the plane valve 1 is in the third positive flushing working position, the first channel 101, the second channel 102 and the third channel 103 are all blocked by the movable valve disc 122, so that the first opening 1101, the second opening 1102 and the third opening 1103 of the plane valve 1 are blocked, 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 eighth channel 108 of the plane valve 1 is connected to the third channel 103, since the first channel 101 and the second channel 102 are respectively blocked by the second fluid control surface 1220 of the movable valve disc 122, and the eighth channel 108 is a conducting blind hole, the movable valve disc 122 blocks the flow of water to the first channel 101, the second channel 102 and the third channel 103, thereby ensuring that only the third water treatment device 53 is positively flushed.

[0134] It is worth noting that when the plane valve 1 is in the third positive flushing working position, the first channel 101, the second channel 102 and the third channel 103 (or the flow channel formed by the eighth channel 108 and the third channel 103) are blocked by the movable valve plate 122 respectively, 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 positively flushed, thereby increasing the intensity of the water flow of the raw water for positively 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 positive flushing working position, the third water treatment device 53 of the water treatment machine of the utility model is positively flushed alone.

[0135] As shown in the attached picture Fig.17 and Figure 18G 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 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 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.

[0136] It is worth noting that the traditional plane valve adopts a valve core structure of a single moving valve plate and a single fixed valve plate, and its moving valve plate often requires a 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 be subject to greater resistance and cause a great loss of kinetic energy of the water flow, so that the flow rate of the water flow is significantly reduced. The plane valve 1 of the water treatment machine of the utility model adopts a three-valve plate structure, and the water flow flowing to the outlet flows upward from the lower valve plate (the first fixed valve plate 121), and the outlet is on the upper valve plate (the second fixed valve plate 123). The change in the flow direction of the water flow is small (roughly), and the resistance encountered by the water flow in the process of changing the flow direction is also small, and the loss of the water flow rate is also significantly reduced. Furthermore, the channel for controlling the flow direction of the water flow set on the fixed valve plate of the existing plane valve with a single fixed valve plate can only be set on a single fixed valve plate. In order to ensure the flow rate of the water flow, the diameter of the fixed valve plate of the plane valve is large and the volume of the entire plane valve is large. The larger the diameter of the plane valve, the more difficult it is to ensure the stability of the movable valve plate when it rotates. In order to ensure the stability of the entire plane valve, the cross-sectional area of ​​the plane valve becomes larger, the valve body needs a thicker wall thickness, and the thickness of the movable valve plate also needs to be increased accordingly, which will not only increase the manufacturing cost of the plane valve, but also make the entire plane valve more cumbersome and difficult to operate. The first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106 and the tenth channel 1010 of the plane valve 1 of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121 and the second fixed valve plate 123, thereby allowing the space occupied by each channel arranged on the fixed valve plate to be larger and increasing the water flow rate. In other words, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106 and the tenth channel 1010 of the planar valve 1 of the water treatment machine of the utility model are respectively arranged on the first fixed valve plate 121 and the second fixed valve plate 123, which can significantly reduce the diameter of the fixed and movable valve plates of the planar valve (or the inner diameter of the valve cavity), the thickness of the movable valve plate and the wall thickness of the valve body, thereby reducing the manufacturing cost of the planar valve and making the entire planar valve structure lighter and easier to operate.

The three-fluid control surface 1223 is blocked to allow raw water to flow in from the second fluid opening 1107 of the valve body 10, flow to the fourth opening 1104 through the seventh channel 107 and the fourth channel 104, and further flow into the third water treatment device 53 from the third water inlet 531. The sewage after positive flushing of the third water treatment device 53 flows out from the third water outlet 532, and then is discharged through the fifth opening 1105, the fifth channel 105, the ninth channel 109, the tenth channel 1010 and the sewage discharge opening 11010. Accordingly, the water treatment machine is in the third positive flushing working state at this time.

[0148] It can be understood that when the second fluid control surface 1220 and the third fluid control surface 1223 of the movable valve plate 122 are respectively arranged on the first fluid control surface 1210 of the first fixed valve plate 121 and the fourth fluid control surface 1230 of the second fixed valve plate 123, the lower end center area 12201 of the second fluid control surface 1220 of the movable valve plate 122 is aligned with the center part 12101 of the first fluid control surface 1210 of the first fixed valve plate 121, and the lower end center area 12201 of the second fluid control surface 1220 of the movable valve plate 122 is aligned with the center part 12101 of the first fluid control surface 1210 of the first fixed valve plate 121.

[0149] Optionally, the first fluid control surface 1210 of the first fixed valve plate 121 of the plane valve 1, the fourth fluid control surface 1230 of the second fixed valve plate 123, the second fluid control surface 1220 and the third fluid control surface 1223 of the movable valve plate 122 are all circular, and the first channel 101 of the plane valve 1, the second connecting portion 1022 of the second channel 102, the fifth channel 105, the first connecting portion 1021 of the second channel 102, the third channel 103 and the fourth channel 104 are all arranged radially. On the first fluid control surface 1210 of the first fixed valve plate 121, the seventh channel 107 and the eighth channel 108 of the planar valve 1 are radially arranged on the second fluid control surface 1220 of the movable valve plate 122, the ninth channel 109 of the planar valve 1 is radially arranged on the second fluid control surface 1220 and the third fluid control surface 1223 of the movable valve plate 122, and the sixth channel 106 and the tenth channel 1010 of the planar valve 1 are radially arranged on the fourth fluid control surface 1230 of the second fixed valve plate 123.

[0150] Preferably, the first channel 101 of the planar valve 1 extends downward and outward from the first fluid control surface 1210 of the first fixed valve plate 121, the second channel 102 extends downward and outward from the first fluid control surface 1210 of the first fixed valve plate 121, the fifth channel 105 extends downward and outward from the first fluid control surface 1210 of the first fixed valve plate 121, the third channel 103 extends downward and outward from the first fluid control surface 1210 of the first fixed valve plate 121, the fourth channel 104 extends downward and outward from the first fluid control surface 1210 of the first fixed valve plate 121, the sixth channel 106 of the planar valve 1 extends upward and outward from the fourth fluid control surface 1230 of the second fixed valve plate 123, and the tenth channel 1010 extends upward and outward from the fourth fluid control surface 1230 of the second fixed valve plate 123.

[0151] As shown in the attached picture FIG. 6A to FIG. 6P As shown, the first valve body portion 11 of the planar valve 1 has a first inner wall 111, and the second valve body portion 13 has a second inner wall 131, wherein the first fixed valve plate 121 is suitable for being arranged in the valve cavity 110 with the first fluid control surface 1210 facing upward, the movable valve plate 122 is suitable for being arranged in the valve cavity 110 with the second fluid control surface 1220 facing downward (the third fluid control surface 1223 facing upward), and the second fixed valve plate 123 is suitable for being arranged in the valve cavity 110 with the fourth fluid control surface 1230 facing downward, wherein the valve cavity 110 is always connected to the seventh channel 107. 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. Those skilled in the art can understand that when the first fixed valve disc 121 is detachably disposed in the first valve body 11, a fixing mechanism is used between the first fixed valve disc 121 and the first valve body 11 to keep the first fixed valve disc 121 and the first valve body 11 synchronized; when the second fixed valve disc 123 is detachably disposed in the second valve body 13, another fixing mechanism is used between the second fixed valve disc 123 and the second valve body 13 to keep the second fixed valve disc 123 and the second valve body 13 synchronized. For example, as shown in the accompanying drawings FIG. 6A to FIG. 6PAs shown, the first fixed valve disc 121 has a first brake member 1213 protruding outward from the edge of the first fixed valve disc 121, and the first inner wall 111 of the first valve body 11 has a first brake portion 1110, wherein the first brake member 1213 of the first fixed valve disc 121 is configured to be able to engage with the first brake portion 1110 of the first inner wall 111 of the first valve body 11, so as to ensure that the first fixed valve disc 121 and the first valve body 11 are synchronized (or do not rotate relative to each other) and ensure that each channel arranged on the first fixed valve disc 121 is connected to the corresponding opening arranged on the first valve body 11 The second fixed valve disc 123 has a second stopper 1233 protruding outward from the edge of the second fixed valve disc 123, and the second inner wall 131 of the second valve body 13 has a second stopper 1310, wherein the second stopper 1233 of the second fixed valve disc 123 is configured to be able to engage with the second stopper 1310 of the second inner wall 131 of the second valve body 13, so as to ensure that the second fixed valve disc 123 and the second valve body 13 are synchronized (or do not rotate relative to each other) and ensure that each channel provided in the second fixed valve disc 123 is connected with the corresponding opening provided in the second valve body 13. It can be understood that when the first fixed valve disc 121 is detachably provided in the first valve body 11, the first fixed valve disc 121 can be manufactured separately, and when the second fixed valve disc 123 is detachably provided in the second valve body 13, the second fixed valve disc 123 can be manufactured separately.
