Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more specifically to a water treatment control valve. Background Technology

[0002] Existing household or industrial water purifiers generally use multi-position ceramic valves for control. For example, the utility model patent CN2573049Y, entitled "Water Purifier Filter Pipeline Device," discloses a method that uses a combination of moving and fixed plates, utilizing the inlet holes and blind holes on the moving plate in conjunction with the six water passages on the fixed plate to achieve water purification, forward flushing, and backwashing functions. Since the inlet holes on the moving plate are used for water intake, it is necessary to ensure that the inlet holes are always open to the water inlet on the valve body. Therefore, this method involves creating a cavity within the valve body to house the moving and fixed plates. This cavity is filled with water, and water enters through the gap between the inlet holes and this cavity. Therefore, to ensure sufficient water flow, the gap between the inlet holes and the cavity cannot be too small. Figure 1 The spacing shown cannot be less than A, which limits the diameter of the moving and fixed plates, thereby reducing the diameter of the through holes and the width of the channels, and reducing the overall flow rate. On the other hand, the water purifier does not have a shut-off function, so in actual use, an additional main valve is required for switching on and off, which is also inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a water treatment control valve that solves the problems of limited flow and the need for an additional main valve in existing technologies by optimizing the valve plate through-hole layout and conduction channel design.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water treatment control valve, comprising a valve body, a fixed valve plate, and a movable valve plate. The valve body is provided with an inlet, an outlet, a drain outlet, an upper water distribution interface, and a lower water distribution interface. The fixed valve plate is provided with a first through hole, a second through hole, a fourth through hole, a fifth through hole, a sixth through hole, and a seventh through hole. The movable valve plate is provided with a second conductive channel, a third conductive channel, and a fourth conductive channel. The first through hole is connected to the inlet, the second and sixth through holes are both connected to the upper water distribution interface, the fourth through hole is connected to the outlet, the fifth through hole is connected to the drain outlet, and the seventh through hole is connected to the lower water distribution interface. The second, third, and fourth conductive channels can all connect to two or more through holes, or one through hole and one closed area, or multiple through holes and multiple closed areas, or one through hole and multiple closed areas, or multiple through holes and one closed area.

[0005] As a further improvement of this utility model, the fixed valve plate and the moving valve plate have the following matching relationship: the second conducting channel connects to the first through hole and the sixth through hole, the third conducting channel connects to the second through hole, and the fourth conducting channel connects to the fourth through hole and the seventh through hole; or, the second conducting channel connects to the first through hole and the second through hole, the third conducting channel connects to the fourth through hole, and the fourth conducting channel connects to the fifth through hole and the seventh through hole; or, the second conducting channel connects to the second through hole, the third conducting channel connects to the fourth through hole and the fifth through hole, and the fourth conducting channel connects to the sixth through hole and the seventh through hole; or, the second conducting channel connects to the fourth through hole, and the third conducting channel connects to the fifth through hole and the sixth through hole.

[0006] As a further improvement of this utility model, the seventh through hole is located at the center of the fixed valve plate, and the first through holes to the sixth through holes are arranged in a circle around the seventh through hole.

[0007] As a further improvement of this utility model, the fixed valve plate also includes a third blind hole, which serves as a closed area on the fixed valve plate.

[0008] As a further improvement of this utility model, the fourth conductive channel includes a central part and a fan-shaped part, and the central part is normally connected to the seventh through hole.

[0009] As a further improvement of this utility model, the first through hole, the second through hole, the fourth through hole, the fifth through hole, the sixth through hole, and the closed area divide the valve plate into six equal parts, each occupying one equal part, and the second and third conducting channels each occupy two equal parts.

[0010] As a further improvement of this utility model, the first through hole, the second through hole, the fourth through hole, the fifth through hole, the sixth through hole, and the closed area divide the fixed valve plate into six equal parts, each occupying one equal part. The seventh through hole is circular and located at the center of the fixed valve plate. The second and third conducting channels each occupy two equal parts, and the fan-shaped part of the fourth conducting channel occupies one equal part.

[0011] Another aspect of this utility model provides a water treatment device, including a control valve and a resin tank. The control valve is installed on the resin tank. The resin tank is provided with an upper water distributor, a central pipe, a lower water distributor, and filter media. The upper and lower water distributors are respectively located at the upper and lower ends of the central pipe. The filter media is filled in the resin tank. The control valve structure is as described in any of the above-mentioned water treatment control valves. The upper water distribution interface is connected to the upper water distributor, and the lower water distribution interface is connected to the upper end of the central pipe.

[0012] The beneficial effect of this utility model is that the first through hole on the fixed valve plate is directly connected to the water inlet. Compared with the method of setting the water inlet channel using the moving valve plate in the prior art, the diameter of the through hole on the fixed valve plate can be set to be larger, thereby significantly increasing the water inlet flow. At the same time, the closed part on the moving valve plate can coincide with the first through hole to achieve the closing effect, thereby increasing the closing function.

[0021] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figures 2 to 4As shown, the water treatment control valve of this embodiment includes a valve body 30, a fixed valve plate 10, and a movable valve plate 20. The valve body 30 is provided with an inlet 31, an outlet 32, a drain outlet 33, an upper water distribution interface 38, and a lower water distribution interface 39. The fixed valve plate 10 is provided with a first through hole 1, a second through hole 2, a fourth through hole 4, a fifth through hole 5, a sixth through hole 6, and a seventh through hole 7. The movable valve plate 20 is provided with a second guiding channel 22, a third guiding channel 23, and a fourth guiding channel 24. The first through hole 1 connects to the inlet. 31 is connected; the second through-hole 2 and the sixth through-hole 6 are both connected to the upper water distribution interface 38; the fourth through-hole 4 is connected to the outlet 32; the fifth through-hole 5 is connected to the drain outlet 33; and the seventh through-hole 7 is connected to the lower water distribution interface 39. The second guiding channel 22, the third guiding channel 23, and the fourth guiding channel 24 can each connect two or more through-holes, one through-hole and one closed area, or multiple through-holes and multiple closed areas, or one through-hole and multiple closed areas, or multiple through-holes and one closed area. During operation, water flows through the inlet 31 into the first through-hole 1, and the switching of different operating conditions is achieved through the guiding channel of the moving valve plate 20. By setting the water inlet on the first through-hole 1 of the fixed valve plate 10, it is not necessary to require a minimum distance A between the moving valve plate 20 and the cavity wall, as in existing technologies. This allows the orifice diameter of the fixed valve plate 10 to be as large as possible, resulting in a higher flow rate. Figures 1 to 2 As shown in the comparison, the spacing of a is significantly smaller than the spacing of A.

[0023] Reference Figures 5 to 8 As shown, further, the fixed valve plate 10 and the moving valve plate 20 have the following cooperative relationship: the second guiding channel 22 guides the first through hole 1 and the sixth through hole 6, the third guiding channel 23 guides the second through hole 2, and the fourth guiding channel 24 guides the fourth through hole 4 and the seventh through hole 7; for operation (filtration): raw water → inlet 31 → first through hole 1 → second guiding channel 22 guides to the sixth through hole 6 → upper water distribution interface 38 → water is evenly distributed through the upper water distributor 41 → upper part of resin tank 40 → filter through filter media (dirt is trapped on the filter media) → lower part of resin tank 40 → lower water distributor 43 → central pipe 42 → lower water distribution interface 39 → seventh through hole 7 → fourth guiding channel 24, guides to the fourth through hole 4 → clean water flows out from outlet 32;

[0024] Alternatively, the second guiding channel 22 connects to the first through hole 1 and the second through hole 2, the third guiding channel 23 connects to the fourth through hole 4, and the fourth guiding channel 24 connects to the fifth through hole 5 and the seventh through hole 7; for forward washing: raw water → inlet 31 → first through hole 1 → second guiding channel 22 guides to the second through hole 2 → upper water distribution interface 38 → water is evenly distributed through the upper water distributor 41 → upper part of resin tank 40 → rinsing dirt on the filter media → lower part of resin tank 40 → lower water distributor 43 → central pipe 42 → lower water distribution interface 39 → seventh through hole 7 → fourth guiding channel 24, connecting to the fifth through hole 5 → wastewater is discharged from the drain outlet 33;

[0025] Alternatively, the second conduction channel 22 connects to the second through hole 2, the third conduction channel 23 connects to the fourth through hole 4 and the fifth through hole 5, and the fourth conduction channel 24 connects to the sixth through hole 6 and the seventh through hole 7. For the closed position: in → stop, when the control valve has a leakage protection function, when leakage is detected, the control valve turns to this position.

[0026] Alternatively, the second guiding channel 22 connects to the fourth through hole 4, and the third guiding channel 23 connects to the fifth through hole 5 and the sixth through hole 6 for backwashing: raw water → inlet 31 → first through hole 1 → fourth guiding channel 24 to the seventh through hole 7 → lower water distribution interface 39 → central pipe 42 → lower water distributor 43 → lower part of resin tank 40 → backwashing of filter media → upper part of resin tank 40 → upper water distributor 41 → upper water distribution interface 38 → sixth through hole 6 → third guiding channel 23 to the fifth through hole 5 → wastewater is discharged from drain outlet 33.

[0027] By switching between four different configurations, functions such as operation (filtration), forward washing, reverse washing, and shutdown can be achieved, avoiding the complex structure of traditional valves that require multiple sets of accessories.

[0028] Reference Figure 4 As shown, the seventh through hole 7 is located at the center of the fixed valve plate 10, and the first through holes 1 to the sixth through holes 6 are arranged in a circle around the seventh through hole 7. The annular distribution of through holes ensures the sealing performance when switching between channels.

[0029] Furthermore, the fixed valve plate 10 also includes a third blind hole 3, which serves as a closed area on the fixed valve plate 10. The blind hole design can cut off the water flow under specific operating conditions to achieve the system pressure holding or shut-off function. At the same time, the blind hole can also store the dirt worn off by the passive valve plate 20 and the fixed valve plate 10, avoiding the sealing problems caused by dirt getting stuck between the passive valve plate 20 and the fixed valve plate 10.

[0030] Reference Figure 4 As shown in b, the fourth conductive channel 24 further includes a central portion and a sector-shaped portion, with the central portion normally connected to the seventh through hole 7. By using the central portion and the sector-shaped portion to form the fourth conductive channel 24, the connection between the seventh through hole 7 and other through holes can be achieved simply and effectively.

[0031] Furthermore, the first through hole 1, the second through hole 2, the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6, along with the enclosed area, divide the fixed valve plate 10 into six equal parts, each occupying one part. The second conduction channel 22 and the third conduction channel 23 each occupy two parts. This equal division structure ensures a precise correspondence between the valve plate rotation angle and function switching, improving operational reliability.

[0032] Furthermore, the first through hole 1, the second through hole 2, the fourth through hole 4, the fifth through hole 5, and the sixth through hole 6, along with the enclosed area, divide the fixed valve plate 10 into six equal parts, each occupying one part. The seventh through hole 7 is circular and located at the center of the fixed valve plate 10. The second and third conducting channels 22 and 23 each occupy two parts, and the fan-shaped portion of the fourth conducting channel 24 occupies one part. This design optimizes space to make the channel layout more compact, reducing the overall size of the valve plate and adapting to the needs of miniaturized equipment.

[0033] Reference Figure 3 As shown, another aspect of this utility model provides a water treatment device, including a control valve and a resin tank 40. The control valve is installed on the resin tank 40. The resin tank 40 is equipped with an upper water distributor 41, a central pipe 42, a lower water distributor 43, and filter media 44. The upper water distributor 41 and the lower water distributor 43 are respectively located at the upper and lower ends of the central pipe 42. The filter media 44 fills the resin tank 40. The control valve structure is as described in any of the above-mentioned water treatment control valves. The upper water distribution interface 38 is connected to the upper water distributor 41, and the lower water distribution interface 39 is connected to the upper end of the central pipe 42. Through the integrated design of the control valve and the resin tank, the pipeline connection is simplified, the system integration is improved, and the uniformity of water distribution and the regeneration effect of the filter media are ensured.

[0034] In summary, by optimizing the through-hole layout and conduction channel structure of the fixed valve plate 10 and the moving valve plate 20, this utility model eliminates the need for a minimum distance A between the moving valve plate 20 and the cavity wall, as required in the prior art. This allows the aperture of the fixed valve plate 10 to be as large as possible, resulting in a higher flow rate.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
