Description

Technical Field

[0001] The invention relates to the technical field of water treatment valve bodies, and in particular to a multifunctional water treatment filter valve. Background Art

[0002] In recent years, control valves with flat sealing structures have been increasingly used in the field of water treatment. Currently, industrial or civil water treatment systems mostly use control valve bodies to switch flow channels. The control valves of the filtration system need to achieve functions such as filtration, backwashing, and forward flushing. The non-filtration processes such as backwashing and forward flushing of the filtration system are collectively referred to as flushing processes. Existing water treatment filter valves mainly change the direction of water flow to achieve operation, backwashing, forward flushing functions, or simple operation and backwashing functions. Filter valves are generally used in industrial water treatment equipment such as carbon filtration and sand filtration, and are widely used in domestic water treatment equipment to remove impurities, residual chlorine, heavy metals, etc., improving people's water quality.

[0003] Most of the existing multifunctional filter valves include a valve body, a movable valve plate and a fixed valve plate placed in the valve body and using an end face rotating seal, the valve body is provided with an inlet and outlet, a water outlet and a sewage outlet, the valve body is provided with a corresponding water passage cavity, and the movable valve plate and the fixed valve plate are provided with corresponding water passage holes. The filtering, backwashing and forward washing functions of the multifunctional filter valve are realized by driving the movable valve plate to rotate at different angles. Since the amount of water entering the filter tank from the water inlet of the valve body is limited by the cross-sectional area of ​​the water inlet hole on the movable valve plate, in order to increase the amount of water passing, it is theoretically necessary to increase the cross-sectional area of ​​the water inlet hole on the movable valve plate. In order to filter a larger flow of raw water, the usual practice is to increase the size of the valve body to increase the volume of the movable valve plate so as to increase the water passage cross-sectional area of ​​the water inlet hole thereon, but this undoubtedly increases the manufacturing cost.

[0004] The movable valve plate of the existing multifunctional filter valve of the same type is divided into 6 equal parts, and the water inlet hole on the movable valve plate occupies 1 equal part. How to break through the existing design while taking into account the size of the valve body and achieving a larger water flow rate has become a technical problem that needs to be urgently solved in the current design process of the multifunctional filter valve. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a multifunctional filter valve for water treatment, so as to solve the technical problem that the multifunctional filter valve in the prior art is difficult to balance the valve body size and achieve a larger water flow rate.

[0006] In order to solve the above problems, the multifunctional water treatment filter valve provided by the present invention adopts the following technical solutions:

[0007] A multifunctional water treatment filter valve comprises an upper valve body and a lower valve body which are detachably connected together, and a movable valve plate which is rotatably assembled between the upper valve body and the lower valve body;

[0008] The upper valve body is provided with a water inlet, a water outlet and a sewage outlet. An upper inner valve cavity and an upper outer valve cavity which are coaxial and separated are arranged inside the upper valve body. The upper inner valve cavity includes a central through hole and a fan-shaped annular upper first chamber, upper second chamber, upper third chamber, upper fourth chamber and upper fifth chamber arranged on the outer circumference of the central through hole. The central through hole is used for a driving member for driving the moving valve plate to rotate to pass through. The upper first chamber and the upper third chamber are communicated with the upper outer valve cavity and the water inlet. The upper second chamber is communicated with the water outlet. The upper fourth chamber is communicated with the sewage outlet. The upper fifth chamber is communicated with the upper fourth chamber.

[0009] The moving valve plate is provided with a transmission hole corresponding to the central through hole. Five moving valve plate partition beams which are equally spaced are arranged on the moving valve plate in the circumferential direction of the transmission hole to divide the circumference of the moving valve plate into five equal parts. The moving valve plate is provided with a water inlet through hole occupying one equal part and a water outlet through hole occupying one equal part. The transmission hole is in positioning cooperation with the transmission member.

[0010] The lower valve body is provided with a first filter element interface for connecting with a filter tank body and a second filter element interface for connecting with a central pipe. A lower inner valve cavity and a lower outer valve cavity which are coaxial and separated are arranged inside the lower valve body. The lower outer valve cavity is communicated with the upper outer valve cavity. The lower inner valve cavity includes a central blind plate and a lower first chamber, lower second chamber, lower third chamber, lower fourth chamber and lower fifth chamber which are arranged in sequence on the outer circumference of the central blind plate. The lower first chamber and the lower fourth chamber are communicated with the first filter element interface. The lower second chamber, the lower third chamber and the lower fifth chamber are communicated with the second filter element interface.

[0011] When the water inlet through hole corresponds to the upper first chamber and the lower first chamber up and down and the water outlet through hole corresponds to the upper second chamber and the lower second chamber up and down, the water treatment multifunctional filter valve is in a working state. When the water inlet through hole corresponds to the upper third chamber and the lower third chamber up and down and the water outlet through hole corresponds to the upper fourth chamber and the lower fourth chamber up and down, the water treatment multifunctional filter valve is in a backwashing state. When the water inlet through hole corresponds to the upper fifth chamber and the lower fifth chamber up and down and the water outlet through hole corresponds to the upper first chamber and the lower first chamber up and down, the water treatment multifunctional filter valve is in a normal flushing state.

[0012] The beneficial effects of the present invention are as follows: The upper valve body and the lower valve body of the water treatment multifunctional filter valve of the present invention can break through the existing design, so that the moving valve plate can be divided into five equal parts. The water inlet through hole on the moving valve plate occupies 1 equal part. Compared with the water treatment multifunctional filter valve with a six-equal-part moving valve plate and the water inlet through hole occupying 1 equal part, under the condition of realizing the same filtering capacity, the valve body volume of the water treatment multifunctional filter valve of the present invention can be made smaller, thus saving more manufacturing costs. Under the condition of a valve body of the same volume, the water treatment multifunctional filter valve of the present invention has a larger water passing flow rate, further improving the working efficiency of the valve body. That is, the water treatment multifunctional filter valve of the present invention can simultaneously meet the requirements of a small valve body size and a larger water passing flow rate.

[0013] Preferably, the upper fourth chamber and the upper fifth chamber communicate with each other in the circumferential direction of the central through hole.

[0014] Preferably, the upper first chamber and the upper third chamber communicate with the upper outer valve chamber in the radial direction of the central through hole.

[0015] Furthermore, the lower first chamber, the lower second chamber, the lower third chamber, the lower fourth chamber, and the lower fifth chamber respectively correspond to the upper first chamber, the upper second chamber, the upper third chamber, the upper fourth chamber, and the upper fifth chamber in the up-and-down direction.

[0016] The beneficial effect is that after the raw water enters from the water inlet, it can directly enter the tank body or the central pipe from the corresponding chamber, and then reach the water outlet or the sewage outlet, which is beneficial to reducing the flow path of the raw water and improving the working efficiency of the water treatment multi-functional filter valve.

[0017] Furthermore, a fixed valve plate is coaxially clamped in the upper valve body. The fixed valve plate is located above the movable valve plate and is rotationally and sealingly matched with the movable valve plate. The fixed valve plate is provided with a central through hole coaxial with the central through hole for the transmission member to pass through. Five equally spaced partition beams are provided on the fixed valve plate in the circumferential direction of the central through hole to divide the fixed valve plate into five fan-shaped ring-shaped water passing holes with equal central angles in the circumferential direction. The five water passing holes respectively communicate with the five chambers of the upper inner valve chamber.

[0018] The beneficial effect is that the cooperation between the fixed valve plate and the movable valve plate can change the flow path of water, and can also prevent the movable valve plate from directly rotating and cooperating with the upper inner valve chamber to cause wear of the end face of the upper inner valve chamber, thereby improving the service life of the water treatment multi-functional filter valve.

[0019] Furthermore, the upper valve body and the lower valve body are assembled by inserting.

[0020] The beneficial effect is that it is convenient for the installation and disassembly of the upper valve body and the lower valve body. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.

[0042] Next, the principles and spirits of the present invention will be elaborated in detail with reference to several representative embodiments of the present invention.

[0043] Embodiment 1 of the water treatment multi-functional filter valve provided by the present invention:

[0044] As Figure 1 shown, the water treatment multi-functional filter valve includes an upper valve body 1, a lower valve body 2, a driving device, a movable valve plate 5, and a control display screen 3. Among them, both the upper valve body 1 and the lower valve body 2 are processed and manufactured by integral injection molding, and the upper valve body 1 and the lower valve body 2 are connected by a plug-in method and can be disassembled. Water inlets 6 and water outlets 7 are respectively arranged on two radially opposite sides of the upper valve body 1. A sewage outlet 8 is arranged on the upper valve body 1 at a position between the water inlet 6 and the water outlet 7. The water inlet 6 and the water outlet 7 are coaxially arranged, and the axis of the sewage outlet 8 is perpendicular to the axis of the water inlet 6. The driving device (not shown in the figure) and the control display screen 3 are both installed on the upper valve body 1. Among them, the driving device is a common gear fork driving structure in the prior art and is used to drive the movable valve plate 5 to rotate.

[0045] As Figure 2 and Figure 3 shown, an upper inner valve cavity and an upper outer valve cavity 9 which are coaxial and separated are provided in the upper valve body 1. The upper inner valve cavity includes a central through hole 10 and a fan-shaped annular upper first chamber 11, upper second chamber 12, upper third chamber 13, upper fourth chamber 14, and upper fifth chamber 15 provided on the outer circumference of the central through hole 10. The central through hole 10 is used for a driving member for driving the movable valve plate 5 to rotate to pass through. The upper second chamber 12 communicates with the water outlet 7, the upper first chamber 11 communicates with the upper outer valve cavity 9, both the upper fourth chamber 14 and the upper fifth chamber 15 communicate with the sewage outlet 8, and the upper outer valve cavity 9 communicates with the water inlet 6.

[0046] In this embodiment, between the upper first chamber 11 and the upper second chamber 12 and the upper fifth chamber 15, and between the upper third chamber 13 and the upper second chamber 12 and the upper fourth chamber 14, they are separated by a partition vertical plate 37. However, the upper fourth chamber 14 and the upper fifth chamber 15 communicate with each other in the circumferential direction of the central through hole 10, that is, there is no partition vertical plate 37 between the upper fourth chamber 14 and the upper fifth chamber 15 at this time, and the two are combined into one chamber. In addition, the upper first chamber 11 and the upper third chamber 13 communicate with the upper outer valve cavity 9 in the radial direction of the central through hole 10, that is, there is no partition between the upper first chamber 11 and the upper third chamber 13 and the upper outer valve cavity 9.

[0047] As Figure 4 and Figure 5 shown, a fixed valve plate 4 is coaxially clamped at the bottom of the upper valve body 1. The fixed valve plate 4 is located above the movable valve plate 5 and is rotationally and sealingly matched with the movable valve plate 5. Under the action of the fixed valve plate 4, it can prevent the movable valve plate 5 from directly rubbing against the upper valve body 1. A central through hole 36 for a transmission member to pass through and coaxial with the central through hole 10 is provided on the fixed valve plate 4. Five equally spaced fixed valve plate partition beams 39 are provided on the fixed valve plate 4 in the circumferential direction of the central through hole 36. The five fixed valve plate partition beams 39 divide the fixed valve plate 4 into five equal parts in the circumferential direction, that is, it is divided into a fan-shaped annular first water passing hole 30, second water passing hole 31, third water passing hole 32, fourth water passing hole 34, and fifth water passing hole 35 with equal central angles and the same cross-sectional area. Among them, the first water passing hole 30 communicates with the upper first chamber 11 up and down, the second water passing hole 31 communicates with the upper second chamber 12 up and down, the third water passing hole 32 communicates with the upper third chamber 13 up and down, the fourth water passing hole 34 communicates with the upper fourth chamber 14 up and down, and the fifth water passing hole 35 communicates with the upper fifth chamber 15 up and down.

[0048] As Figure 6 and Figure 7As shown in the figure, a driving hole 16 corresponding to the central through hole 10 is provided on the moving valve plate 5, and the driving hole 16 is in positioning fit with the transmission part in the driving device. Five equally spaced moving valve plate dividing beams 38 are provided on the moving valve plate 5 in the circumferential direction of the driving hole 16. The five moving valve plate dividing beams 38 divide the circumference of the moving valve plate into five equal parts, which are in sequence the water inlet through hole 17, the water outlet through hole 18, the first blind plate 19, the second blind plate 20, and the third blind plate 21. The central angles corresponding to the water inlet through hole 17, the water outlet through hole 18, the first blind plate 19, the second blind plate 20, and the third blind plate 21 are all 72°, and their cross-sectional areas in the horizontal direction are the same, and are all equal to the horizontal cross-sectional areas of the first water passing hole 30, the second water passing hole 31, the third water passing hole 32, the fourth water passing hole 34, and the fifth water passing hole 35.

[0049] As Figure 8 , Figure 9 , Figure 10 and Figure 11 shown, a first filter element interface 22 for connecting with the filter tank body and a second filter element interface 23 for connecting with the central pipe are provided on the lower valve body 2. A lower inner valve cavity and a lower outer valve cavity 24 which are coaxial and separated are provided in the lower valve body 2, and the lower outer valve cavity 24 communicates with the upper outer valve cavity 9 up and down. The lower inner valve cavity includes a central blind plate 40 and a lower first chamber 25, a lower second chamber 26, a lower third chamber 27, a lower fourth chamber 28, and a lower fifth chamber 29 which are arranged in sequence on the outer circumference of the central blind plate 40. The lower first chamber 25, the lower second chamber 26, the lower third chamber 27, the lower fourth chamber 28, and the lower fifth chamber 29 correspond to the upper first chamber 11, the upper second chamber 12, the upper third chamber 13, the upper fourth chamber 14, and the upper fifth chamber 15 up and down respectively. The lower first chamber 25 and the lower fourth chamber 28 are both communicated with the first filter element interface 22, and the lower second chamber 26, the lower third chamber 27, and the lower fifth chamber 29 are all communicated with the second filter element interface 23.

[0050] The working process of the water treatment multi-functional filter valve of the present invention is as follows:

[0051] As Figure 12 and Figure 13As shown, the multi-functional water treatment filter valve is in the working state. At this time, the water inlet through-hole 17 on the movable valve plate 5 corresponds vertically to the upper first chamber 11, the first water passing hole 30, and the lower first chamber 25; the water outlet through-hole 18 corresponds vertically to the upper second chamber 12, the second water passing hole 31, and the lower second chamber 26; the first blind plate 19 corresponds vertically to the upper third chamber 13, the third water passing hole 32, and the lower third chamber 27; the second blind plate 20 corresponds vertically to the upper fourth chamber 14, the fourth water passing hole 34, and the lower fourth chamber 28; the third blind plate 21 corresponds vertically to the upper fifth chamber 15, the fifth water passing hole 35, and the lower fifth chamber 29. The flow path of the raw water is: water inlet 6 → upper outer valve chamber 9 → upper first chamber 11 → first water passing hole 30 → water inlet through-hole 17 → lower first chamber 25 → first filter element interface 22 → filter tank body → central pipe → second filter element interface 23 → lower second chamber 26 → water outlet through-hole 18 → second water passing hole 31 → upper second chamber 12 → water outlet 7.

[0052] As Figure 14 and Figure 15 shown, the multi-functional water treatment filter valve is in the backwashing state (the movable valve plate rotates 144° counterclockwise compared to its position in the working state, and the counterclockwise direction here is with reference to the direction from the upper valve body to the lower valve body). At this time, the water inlet through-hole 17 on the movable valve plate 5 corresponds vertically to the upper third chamber 13, the third water passing hole 32, and the lower third chamber 27; the water outlet through-hole 18 corresponds vertically to the upper fourth chamber 14, the fourth water passing hole 34, and the lower fourth chamber 28; the first blind plate 19 corresponds vertically to the upper fifth chamber 15, the fifth water passing hole 35, and the lower fifth chamber 29; the second blind plate 20 corresponds vertically to the upper first chamber 11, the first water passing hole 30, and the lower first chamber 25; the third blind plate 21 corresponds vertically to the upper second chamber 12, the second water passing hole 31, and the lower second chamber 26. The flow path of the raw water is: water inlet 6 → upper outer valve chamber 9 → upper third chamber 13 → third water passing hole 32 → water inlet through-hole 17 → lower third chamber 27 → second filter element interface 23 → central pipe → filter tank body → first filter element interface 22 → lower fourth chamber 28 → water outlet through-hole 18 → fourth water passing hole 34 → upper fourth chamber 14 → sewage outlet 8.

[0053] As Figure 16 and Figure 17As shown, the multi-functional water treatment filter valve is in the flushing state (the moving valve plate rotates 288° counterclockwise compared to its position in the working state, and the counterclockwise direction here is with reference to the direction from the upper valve body to the lower valve body). At this time, the water inlet through-hole 17 corresponds vertically to the upper fifth chamber 15, the fifth water passage hole 35, and the lower fifth chamber 29. The water outlet through-hole 18 corresponds vertically to the upper first chamber 11, the first water passage hole 30, and the lower first chamber 25. The first blind plate 19 corresponds vertically to the upper second chamber 12, the second water passage hole 31, and the lower second chamber 26. The second blind plate 20 corresponds vertically to the upper third chamber 13, the third water passage hole 32, and the lower third chamber 27. The third blind plate 21 corresponds downward to the upper fourth chamber 14, the fourth water passage hole 34, and the lower fourth chamber 28. At this time, the flow path of the raw water is: water inlet 6 → upper outer valve chamber 9 → upper first chamber 11 → first water passage hole 30 → water outlet through-hole 18 → lower first chamber 25 → first filter element interface 22 → filter tank → central pipe → second filter element interface 23 → lower fifth chamber 29 → water inlet through-hole 17 → fifth water passage hole 35 → upper fifth chamber 15 → sewage outlet 8.

[0054] The upper valve body and the lower valve body of the multi-functional water treatment filter valve of the present invention can break through the existing design, enabling the moving valve plate to be divided into five equal parts, and the water inlet through-hole on the moving valve plate accounts for 1 equal part. Compared with the multi-functional water treatment filter valve with a six-equal-part moving valve plate and the water inlet through-hole accounting for 1 equal part, under the condition of realizing the same filtering capacity, the valve body volume of the multi-functional water treatment filter valve of the present invention can be made smaller, thus saving more manufacturing costs; under the condition of the same volume valve body, the multi-functional water treatment filter valve of the present invention has a larger water flow rate, further improving the working efficiency of the valve body, that is, the multi-functional water treatment filter valve of the present invention can simultaneously meet the requirements of a small valve body size and a larger water flow rate.

[0055] Embodiment 2 of the multi-functional water treatment filter valve provided by the present invention:

[0056] The main difference from Embodiment 1 is that: in Embodiment 1, the upper fourth chamber and the upper fifth chamber communicate with each other in the circumferential direction of the central through-hole. In this embodiment, a partition is provided between the upper fourth chamber and the upper fifth chamber, and a water flow hole for water to flow from the upper fifth chamber into the upper fourth chamber is opened on the partition.

[0057] Embodiment 3 of the multi-functional water treatment filter valve provided by the present invention:

[0058] The main difference from Embodiment 1 is that: in Embodiment 1, a fixed valve plate is provided to prevent the moving valve plate from directly wearing against the end face of the upper valve body. In this embodiment, the fixed valve plate is not provided, and the moving valve plate directly contacts the end face of the upper valve body when rotating. At this time, to prevent wear, wear-resistant treatment can be performed on the end face of the upper valve body and the moving valve plate, such as coating a wear-resistant agent to prevent wear.

[0059] Based on the above description in this specification, those skilled in the art can also understand the terms used as follows, such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer" (this part of the text needs to be adjusted and replaced according to the text adopted in each case), etc. The terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationship cannot be understood or interpreted as a limitation to the solution of the present invention.

[0060] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
