Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and particularly to a multifunctional water treatment softening valve. Background Art

[0002] Currently, industrial or domestic water treatment systems usually use multifunctional control valves to switch water flow channels, thereby realizing functions such as making soft water, backwashing, salt absorption regeneration, and normal flushing.

[0003] The most common multifunctional control valve is the planar multi-way valve. For example, a double static plate planar sealed multi-way valve disclosed in a Chinese invention patent with the authorization announcement number CN205781072U includes a handle fixedly arranged at the upper end of a shaft, an upper valve arranged below the handle. The inner cavity of the upper valve is divided into a water inlet cavity, a water outlet cavity, and a sewage discharge cavity. The side wall of the upper valve is processed with a water inlet connected to the water inlet cavity, a water outlet connected to the water outlet cavity, and a sewage discharge port connected to the sewage discharge cavity. The lower end of the upper valve is fixedly provided with a lower valve. The lower valve is processed with an upper filling port channel and a lower filling port channel. An upper static plate, a moving plate, and a lower static plate are sequentially arranged on the shaft between the upper valve and the lower valve. The moving plate is fixedly connected to the shaft. The moving plate is processed with a water passing hole. The upper static plate is processed with a working position hole. The lower static plate has the same structure as the upper static plate. The upper and lower surfaces of the moving plate are respectively tightly attached and sealed to the upper and lower static plates.

[0004] When the above double static plate planar sealed multi-way valve is working, by rotating the moving plate and adjusting the position of the moving plate, although three functions of operation, backwashing, and normal flushing can be realized, it does not have the function of separate salt absorption regeneration. If salt absorption regeneration is to be realized, on the basis of the above structure, regeneration needs to be carried out simultaneously with the backwashing process, that is, salt is absorbed during the backwashing process, which is a countercurrent regeneration treatment method. It is difficult to freely adjust the working time of these two processes of backwashing and salt absorption regeneration, and the use effect in actual water treatment is poor.

[0005] Another example is a double static plate multifunctional softening valve and its water treatment device disclosed in the application publication number CN111520509A. Although the separation of backwashing and regeneration is achieved, its moving valve plate enters water from the side and needs to change its own thickness according to the demand of the water inflow. The manufacturing cost of its main components such as the moving valve plate is relatively high. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a multifunctional water treatment softening valve to solve the technical problems of imperfect functions and relatively high use costs of existing water treatment control valves.

[0007] To solve the above problems, the multifunctional water treatment softening valve provided by the present invention adopts the following technical solutions:

[0008] Water treatment multi-functional softening valve, comprising an upper valve body, a lower valve body, a moving valve plate and a driving device, the driving device is in transmission connection with the moving valve plate to drive the moving valve plate to rotate, and the moving valve plate is rotationally and sealingly matched with both the upper valve body and the lower valve body;

[0009] The side wall of 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 in the upper valve body. The upper inner valve cavity includes a central through hole and a water inlet cavity, a water outlet cavity and a sewage cavity with a fan-shaped cross-section distributed circumferentially along the central through hole. The central angle corresponding to the water inlet cavity is 180°, the central angle corresponding to the water outlet cavity is 60°, and the central angle corresponding to the sewage cavity is 120°;

[0010] A transmission hole corresponding to the central through hole up and down is arranged on the moving valve plate. Water inlet through holes, water outlet through holes, a first blind plate area and a second blind plate area are arranged on the moving valve plate in the circumferential direction of the transmission hole. The water inlet through holes and the water outlet through holes are oppositely arranged and the central angles corresponding to both of them are 60°;

[0011] The side wall of the lower valve body is provided with a regeneration port and a water passing port communicated through a jet ejector, the bottom is provided with a first filter element interface for communicating with a treatment tank body and a second filter element interface for communicating with a central pipe. A lower inner valve cavity and a lower outer valve cavity which are coaxial and separated are arranged in the lower valve body. The lower inner valve cavity includes a central blind hole and a first working cavity, a second working cavity, a third blind cavity, a fourth blind cavity, a fifth working cavity, a sixth working cavity, a seventh working cavity, an eighth blind cavity and a ninth working cavity arranged in sequence along the circumferential direction of the central blind hole. The central angles corresponding to the first working cavity, the sixth working cavity and the ninth working cavity are all 60°, and the central angles corresponding to the second working cavity, the third blind cavity, the fourth blind cavity, the fifth working cavity, the seventh working cavity and the eighth blind cavity are all 30°;

[0012] The lower openings of the first working cavity, the fifth working cavity, the seventh working cavity and the third blind cavity are all communicated with the first filter element interface, the second working cavity, the sixth working cavity and the ninth working cavity are all communicated with the second filter element interface, the fourth blind cavity is communicated with the regeneration port, and the lower openings of the fifth working cavity and the third blind cavity are communicated with the water passing port.

[0013] Further, lubricating layers are provided on both the upper surface and the lower surface of the moving valve plate.

[0014] Further, ten valve plate partition beams are arranged at intervals in the circumferential direction of the transmission hole on the moving valve plate to respectively divide the first blind plate area and the second blind plate area into four blind plates with a central angle of 30° each; each working cavity and blind cavity of the lower valve body are separated from each other by a lower valve body partition plate extending in the up and down direction, and each chamber of the upper valve body is separated from each other by an upper valve body partition plate extending in the up and down direction.

[0015] Further, the upper valve body and the lower valve body are assembled by insertion.

[0016] Further, the upper valve body and the lower valve body are integrally injection-molded.

[0017] The beneficial effects of the water treatment multi-functional softening valve of the present invention are as follows:

[0018] Based on the existing upper valve body, the water treatment multi-functional softening valve of the present invention innovatively improves the structure of the lower valve body. After the driving device drives the moving valve plate to rotate by a corresponding angle, functions such as soft water production, backwashing, salt absorption regeneration, and normal washing can be individually achieved. The functions of the valve body are more complete, and each function is independent of each other and does not affect each other. Furthermore, the free adjustment of the time of each working process can be realized; in addition, the salt absorption regeneration process is a co-current regeneration. The equipment and operation in this way are simpler and more in line with the actual use situation; the water treatment multi-functional softening valve of the present invention is more compact and reasonable in structure, saves materials at the same time, and has a lower cost.

Detailed implementation manners

[0037] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Those skilled in the art should know that the following described embodiments are 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 efforts fall within the protection scope of the present invention.

[0038] Next, with reference to several representative embodiments of the present invention, the principles and spirits of the present invention will be elaborated in detail.

[0039] Embodiment 1 of the water treatment multifunctional softening valve provided by the present invention:

[0040] As Figure 1 and Figure 2 shown, the water treatment multifunctional softening valve includes an upper valve body 1, a lower valve body 2, a moving valve plate 14, a driving device 7, a jet injector 35, and an operation screen 3.

[0041] Specifically, both the upper valve body 1 and the lower valve body 2 are processed and manufactured by an integrally injection-molded method, and the upper valve body 1 and the lower valve body 2 are assembled by a plug-in method, and the two can be disassembled. On the upper valve body 1, a water inlet 4 and a water outlet 5 are respectively provided on two radially opposite sides, and a sewage outlet 6 is provided on the upper valve body 1 at a position between the water inlet 4 and the water outlet 5. The water inlet 4 and the water outlet 5 are coaxially arranged, and the axis of the sewage outlet 6 is perpendicular to the axis of the water inlet 4. The operation screen 3 and the driving device 7 are both installed on the upper valve body 1. The driving device 7 is a common gear fork driving structure in the prior art, including a motor, a driving gear connected to the output shaft of the motor, a driven gear meshing with the driving gear, and a lever 8 coaxially fixed on the driven gear.

[0042] As Figure 3 shown, an upper inner valve cavity and an upper outer valve cavity are provided coaxially and separated inside the upper valve body 1. The upper inner valve cavity includes a central through hole 9 and a water inlet cavity 10, a water outlet cavity 11, and a sewage cavity 12 distributed circumferentially along the central through hole 9. The water inlet cavity 10, the water outlet cavity 11, and the sewage cavity 12 are separated from each other by an upper valve body partition plate 13 extending in the up and down direction, and the horizontal cross-sections of the water inlet cavity 10, the water outlet cavity 11, and the sewage cavity 12 are in a fan-shaped ring shape. In this embodiment, the central angle corresponding to the water inlet cavity 10 is 180°, the central angle corresponding to the water outlet cavity 11 is 60°, and the central angle corresponding to the sewage cavity 12 is 120°. The water inlet cavity 10 is communicated with the water inlet 4, the water outlet cavity 11 is communicated with the water outlet 5, and the sewage cavity 12 is communicated with the sewage outlet 6.

[0043] As Figure 4As shown, a transmission hole 15 corresponding to the above-mentioned central through-hole 9 is provided on the movable valve plate 14. The lever 8 passes through the central through-hole 9 and cooperates with the transmission hole 15 to drive the movable valve plate 14 to rotate when the motor is started. Ten movable valve plate dividing beams are provided on the movable valve plate 14 in the circumferential direction of the transmission hole 15 to divide the movable valve plate 14 into a water inlet through-hole 16, a water outlet through-hole 17, a first blind plate area 18, and a second blind plate area 19. Among them, the water inlet through-hole 16 and the water outlet through-hole 17 are arranged oppositely and symmetric about the lever 8, and the central angles corresponding to the water inlet through-hole 16 and the water outlet through-hole 17 are both 60°. The first blind plate area 18 and the second blind plate area 19 are also symmetric about the lever 8, and both blind plate areas include four blind plates with a central angle of 30°.

[0044] As Figure 2 and Figure 5 shown, a regeneration port 20 and a water passing port 21 are provided on the side wall of the lower valve body 2. The regeneration port 20 and the water passing port 21 are connected through a jet ejector 35. The jet ejector 35 is a prior art, and its structure will not be introduced in detail here. The jet ejector 35 is connected to a salt box through a pipeline. A float ball is provided in the salt box. After the salt water in the salt box is full, the float ball closes the salt bucket opening. As Figure 7 shown, a first filter element interface 32 and a second filter element interface 33 are provided coaxially at the bottom of the lower valve body 3. The first filter element interface 32 is used to communicate with the treatment tank body, and the second filter element interface 33 is used to communicate with the central pipe. As Figure 5 and Figure 6 shown, a lower inner valve cavity and a lower outer valve cavity are provided coaxially and separated in the lower valve body 3. The lower inner valve cavity includes a central blind hole 22 and a plurality of lower valve body dividing plates 34 arranged in sequence along the circumferential direction of the central blind hole 22 to divide the lower inner valve cavity into a first working position cavity 23, a second working position cavity 24, a third blind cavity 25, a fourth blind cavity 26, a fifth working position cavity 27, a sixth working position cavity 28, a seventh working position cavity 29, an eighth blind cavity 30, and a ninth working position cavity 31. Among them, the central blind hole 22 is coaxial with the central through-hole 9. The central angles corresponding to the first working position cavity 23, the sixth working position cavity 28, and the ninth working position cavity 31 are all 60°. The central angles corresponding to the second working position cavity 24, the third blind cavity 25, the fourth blind cavity 26, the fifth working position cavity 27, the seventh working position cavity 29, and the eighth blind cavity 30 are all 30°. In addition, the first working position cavity 23, the fifth working position cavity 27, and the seventh working position cavity 29 are all connected vertically with the first filter element interface 32. The second working position cavity 24, the sixth working position cavity 28, and the ninth working position cavity 31 are all connected vertically with the second filter element interface 33. The water passing port 21 is connected to the lower opening of the third blind cavity 25 and at the same time to the side opening of the fifth working position cavity 27; the regeneration port 20 is connected to the side opening of the fourth blind cavity 26.

[0045] The moving valve plate 14 is located between the upper valve body 2 and the lower valve body 3. The outer circle of the moving valve plate 14 coincides with the outer circles of the upper inner valve cavity and the lower inner valve cavity in the vertical projection. When the moving valve plate 14 rotates by a corresponding angle, the valve plate partition beam 36 on the moving valve plate 14 coincides with the lower valve body partition plate 34 and the upper valve body partition plate 13 in the vertical projection, realizing the rotational sealing fit between the moving valve plate 14 and the upper valve body 1 and the lower valve body 2. To reduce the wear of the moving valve plate 14, lubricating layers are provided on both the upper surface and the lower surface of the moving valve plate 14.

[0046] The water treatment multifunctional softening valve of the present invention drives the moving valve plate 14 to rotate through the driving device 7, and can realize processes such as water production, backwashing, regeneration, normal flushing, and salt tank water injection. The specific working process is as follows:

[0047] As Figure 8 and Figure 9 shown, the water treatment multifunctional softening valve is in the water production state. At this time, the water inlet through hole 16 on the moving valve plate 14 corresponds to the first working position cavity 23 up and down and is communicated with the water inlet cavity 10. The water outlet through hole 17 on the moving valve plate 14 corresponds to the water outlet cavity 11 and the sixth working position cavity 28 up and down and is communicated. The flow path of the raw water is: water inlet 4 → water inlet cavity 10 → water inlet through hole 16 → first working position cavity 23 → first filter element interface 32 → treatment tank body → central pipe → second filter element interface 33 → sixth working position cavity 28 → water outlet through hole 17 → water outlet cavity 11 → water outlet 5.

[0048] As Figure 10 and Figure 11 shown, the water treatment multifunctional softening valve is in the backwashing state (the position of the moving valve plate 14 rotates 60° counterclockwise compared to the water production state, and the counterclockwise direction here is with reference to the direction of looking from the upper valve body 1 to the lower valve body 2). At this time, the water inlet through hole 16 on the moving valve plate 14 corresponds to the second working position cavity 24 and the third blind cavity 25 up and down and is communicated with the water inlet cavity 10. The water outlet through hole 17 on the moving valve plate 14 corresponds to the seventh working position cavity 29 and the eighth blind cavity 30 up and down and is communicated with the sewage discharge cavity 12. The flow path of the raw water is: water inlet 4 → water inlet cavity 10 → water inlet through hole 16 → second working position cavity 24 → second filter element interface 33 → central pipe → treatment tank body → first filter element interface 32 → seventh working position cavity 29 → water outlet through hole 17 → sewage discharge cavity 12 → sewage outlet 6.

[0049] As Figure 12 and Figure 13As shown, the water treatment multi-functional softening valve is in the regeneration state (the moving valve plate 14 rotates counterclockwise by 90° compared to its position in the water production state). At this time, the water inlet through-hole 16 on the moving valve plate 14 corresponds to the third blind cavity 25 and the fourth blind cavity 26 up and down, and is communicated with the water inlet cavity 10; the water outlet through-hole 17 on the moving valve plate 14 corresponds to the eighth blind cavity 30 and part of the ninth working position cavity 31 up and down, and is communicated with the sewage discharge cavity 12. The flow path of the raw water is: water inlet 4 → water inlet cavity 10 → water inlet through-hole 16 → fourth blind cavity 26 → regeneration port 20 → injector 35. After passing through the injector 35, negative pressure is generated to suck the brine in the salt tank, and after mixing with the raw water, it flows into the fifth working position cavity 27 through the water outlet 21, passes through the first filter element interface 32 and finally flows into the treatment tank body; then the flow path of the water is: central pipe → second filter element interface 33 → ninth working position cavity 31 → water outlet through-hole 17 → sewage discharge cavity 12 → sewage discharge port 6.

[0050] As Figure 14 and Figure 15 shown, the water treatment multi-functional softening valve is in the flushing state (the moving valve plate 14 rotates counterclockwise by 120° compared to its position in the water production state). At this time, the water inlet through-hole 16 on the moving valve plate 14 corresponds to the fourth blind cavity 26 and the fifth working position cavity 27 up and down, and is communicated with the water inlet cavity 10; the water outlet through-hole 17 on the moving valve plate 14 corresponds to the ninth working position cavity 31 up and down, and is communicated with the sewage discharge cavity 12. The flow path of the raw water is: water inlet 4 → water inlet cavity 10 → water inlet through-hole 16 → fifth working position cavity 27 → first filter element interface 32 → treatment tank body → central pipe → second filter element interface 33 → ninth working position cavity 31 → water outlet through-hole 17 → sewage discharge cavity 12 → sewage discharge port 6. After the flushing is completed, the moving valve plate 14 rotates counterclockwise by 240° on this basis to enter the water production state again.

[0051] In any process after the regeneration process is completed, water can be injected into the salt tank, and the water level in the salt tank is controlled by a float switch.

[0052] The water treatment multi-functional softening valve of the present invention adopts the form of an upper valve body and a lower valve body, and can independently realize functions such as soft water production, backwashing, salt absorption regeneration, and flushing. The functions of the entire softening valve are more complete, and each function is independent of each other and does not affect each other, so that the free adjustment of the time of each working process can be realized. In addition, the salt absorption regeneration process of the water treatment multi-functional softening valve of the present invention is a co-current regeneration. The equipment and operation in this way are simpler and more in line with the actual use situation. The valve body structure is more compact and reasonable, while saving materials and having a lower manufacturing cost.

[0053] Embodiment 2 of the water treatment multi-functional softening valve provided by the present invention:

[0054] The main difference from Embodiment 1 is as follows: In Embodiment 1, lubrication and anti-wear are achieved by providing lubricating layers on the upper and lower surfaces of the movable valve plate. In this embodiment, lubrication can also be achieved by providing two static valve plates in the upper valve body and the lower valve body.

[0055] Embodiment 3 of the water treatment multi-functional softening valve provided by the present invention:

[0056] The main difference from Embodiment 1 is as follows: In Embodiment 1, the movable valve plate is divided into a water inlet through hole, a water outlet through hole, a first blind plate area, and a second blind plate area by a valve plate partition beam. In this embodiment, no valve plate partition beam is provided on the movable valve plate, and the areas other than the water inlet through hole and the water outlet through hole are all blind plates.

[0057] According to the above description of this specification, those skilled in the art can also understand the following terms used, such as the terms indicating the orientation or positional relationship, such as "upper", "lower", "thickness", "bottom", "inner", "outer", etc., 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 indicating the orientation or positional relationship cannot be understood or interpreted as a limitation to the solution of the present invention.

[0058] In addition, in the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
