However, in the actual operation process, the operation is relatively cumbersome, resulting in a large number of valves, large volume, high cost and low integration. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to at least overcome one of the defects of the prior art that when realizing multi-way adjustment, multiple valves are mostly used for the on-off of different flow paths, which easily leads to a large number of valves, high cost and low integration, so as to provide an integrated valve and a water purification device having the integrated valve.

[0004] The present invention provides an integrated valve, including: a valve body, on which a valve body inlet, at least three chambers and at least three outlets are respectively constructed. The at least three chambers include a first chamber, a second chamber and a third chamber, and the at least three outlets include a first outlet, a second outlet and a third outlet; a valve core, disposed on the upper end surface of the valve body, on which a valve core inlet and at least three valve core outlets are constructed. The first valve core outlet of the valve core communicates with the first chamber, the second valve core outlet of the valve core communicates with the second chamber, the third valve core outlet of the valve core communicates with the third chamber of the valve body, and the valve core inlet communicates with the valve body inlet; and a turntable, on which a plurality of flow paths are respectively constructed. By rotating the turntable, the corresponding flow paths are connected to the corresponding valve core inlets and valve core outlets to switch each flow path.

[0005] Wherein, the turntable includes a first flow path and a second flow path. When the integrated valve is in the first position, the first flow path and the second flow path are arranged in parallel and connected to the outside.

[0006] Wherein, the first flow path communicates with the valve core inlet and the first valve core outlet, and the second flow path communicates with the valve core inlet and the second valve core outlet.

[0007] Wherein, the turntable further includes a third flow path and a fourth flow path. The third flow path communicates with the valve core inlet and the first valve core outlet, and the fourth flow path communicates with the second valve core outlet and the third valve core outlet; or the third flow path communicates with the valve core inlet and the second valve core outlet, and the fourth flow path communicates with the first valve core outlet and the third valve core outlet.

[0008] Among them, when the integrated valve is in the first position and the turntable rotates to the first position, the valve core inlet of the valve core communicates with the first valve core outlet through the first flow path of the turntable, and the valve core inlet communicates with the second valve core outlet through the second flow path; the first valve core outlet communicates with the first chamber of the valve body, and then the fluid flows out to the outside through the first outlet of the valve body; the second valve core outlet communicates with the second chamber of the valve body, and then the fluid flows out to the outside through the second outlet of the valve body.

At this time, the first valve core outlet communicates with the first chamber of the valve body, and the fluid flows out to the outside through the first outlet of the valve body; the fluid then flows back to the second outlet of the valve body through an external pipeline, enters the second chamber, and then flows into the third valve core outlet through the fourth flow path of the turntable via the second valve core outlet, flows into the third chamber of the valve body through the third valve core outlet, and the fluid is discharged to the outside through the third outlet of the valve body.

[0010] Among them, when the integrated valve is in the third position, the turntable rotates to the third position, the valve core inlet communicates with the second valve core outlet through the third flow path of the turntable, and the first valve core outlet communicates with the third valve core outlet through the fourth flow path. At this time, the second valve core outlet communicates with the second chamber of the valve body, and the fluid flows out to the outside through the second outlet of the valve body. The fluid then flows back to the first outlet of the valve body through an external pipeline, enters the first chamber, and then flows into the third valve core outlet through the fourth flow path of the turntable via the first valve core outlet, flows into the third chamber of the valve body through the third valve core outlet, and the fluid is discharged to the outside through the third outlet of the valve body.

[0011] Among them, the integrated valve further includes a motor and a gland. The gland is arranged on the turntable, and a fixing hole adapted to the motor shaft of the motor is formed on the turntable. The motor is arranged on the gland, and the motor and the gland are connected into one body through fasteners. A through hole is formed on the gland, and the motor shaft of the motor passes through the through hole and can be inserted into the fixing hole. Among them, by rotating the motor shaft, the turntable is driven to rotate.

[0012] Among them, the gland and the valve body are fixedly connected into one body through fasteners to fix the turntable and the valve core between the gland and the valve body.

[0013] Among them, both the turntable and the valve core are made of hard materials.

[0014] Among them, the hard material includes ceramics.

[0015] Among them, the integrated valve further includes a seal disposed between the valve core and the valve body. The seal can seal each chamber of the valve body and form independent chambers in the valve body to connect with each valve core outlet of the valve core.

[0016] Among them, the fourth flow path is configured as a waist-shaped groove. When the integrated valve is in the second position or the third position, the waist-shaped groove will rotate to communicate with two adjacent valve core outlets in the valve core.

[0017] According to the second aspect of the present invention, a water purification device is further provided, including the above-mentioned integrated valve.

[0018] Compared with the prior art, the integrated valve provided by the present invention has the following advantages:

[0019] In this application, a valve body inlet, a first chamber, a second chamber, a first outlet, a second outlet, and a third outlet are configured on the valve body.

At the same time, by respectively configuring a plurality of flow paths on the turntable, through the rotation of the turntable, the corresponding flow paths are promoted to be connected with the corresponding valve core inlet and valve core outlet to switch each flow path. It can be seen that by adding the integrated valve of this application, the situation of using multiple valves simultaneously can be saved, and it has the advantages of small volume, low cost, and high integration.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] As Figures 1 to 9 shown, the figure schematically shows that the integrated valve includes a valve body 1, a valve core 2, and a turntable 3.

[0037] In the embodiment of the present application, a valve body inlet 11, at least three chambers, and at least three outlets are respectively formed on the valve body 1. The at least three chambers include a first chamber 12, a second chamber 13, and a third chamber (not shown in the figure), and the at least three outlets include a first outlet 14, a second outlet 15, and a third outlet (not shown in the figure).

[0038] The valve core 2 is arranged on the upper end surface of the valve body 1. A valve core inlet 21 and at least three valve core outlets are formed on the valve core 2. The first valve core outlet 22 of the valve core 2 communicates with the first chamber 12, the second valve core outlet 23 of the valve core 2 communicates with the second chamber 13, the third valve core outlet (not shown in the figure) of the valve core 2 communicates with the third chamber of the valve body 1, and the valve core inlet 21 communicates with the valve body inlet 11.

[0039] A plurality of flow paths are respectively constructed on the turntable 3. By rotating the turntable 3, the corresponding flow paths are made to communicate with the corresponding valve core inlets 21 and valve core outlets, so as to switch each of the flow paths. Specifically, in the present application, a valve body inlet 11, at least three chambers and at least three outlets are constructed on the valve body 1. The at least three chambers include a first chamber 12 and a second chamber 13. The at least three outlets include a first outlet 14, a second outlet 15 and a third outlet. At the same time, a valve core inlet 21 and at least three valve core outlets are constructed on the valve core 2. The first valve core outlet 22 of the valve core 2 communicates with the first chamber 12. The second valve core outlet 23 of the valve core 2 communicates with the second chamber 13, and the third valve core outlet communicates with the third chamber of the valve body. The valve core inlet 21 communicates with the valve body inlet 11. At the same time, a plurality of flow paths are respectively constructed on the turntable 3. By rotating the turntable 3, the corresponding flow paths are made to communicate with the corresponding valve core inlets 21 and valve core outlets, so as to switch each of the flow paths. It can be seen that by adding the integrated valve of the present application, the situation of using multiple valves simultaneously can be omitted, and it has the advantages of small volume, low cost and high integration degree.

[0040] It should be noted that the first outlet 14 is arranged on the first chamber 12 and communicates with the first chamber 12. The second outlet 15 is arranged on the second chamber 13 and communicates with the second chamber 13. The third outlet is arranged on the third chamber and communicates with the third chamber.

[0041] In a preferred embodiment of the present application, the turntable 3 includes a first flow path 31 and a second flow path 32. Wherein, when the integrated valve is in the first position, the first flow path 31 and the second flow path 32 are arranged in parallel and connected to the outside.

[0042] As Figure 1 and Figure 5 shown, in a preferred embodiment of the present application, the first flow path 31 communicates with the valve core inlet 21 and the first valve core outlet 22, and the second flow path 32 communicates with the valve core inlet 21 and the second valve core outlet 23.

[0043] In a preferred embodiment of the present application, the turntable 3 further includes a third flow path 33 and a fourth flow path (not shown in the figure). The third flow path 33 communicates with the valve core inlet 21 and the first valve core outlet 22, and the fourth flow path communicates with the second valve core outlet 23 and the third valve core outlet. Specifically, when the integrated valve is applied in the use environment of an ultrafiltration membrane, the ultrafiltration membrane is two ultrafiltration membranes in parallel, namely a first ultrafiltration membrane and a second ultrafiltration membrane (not shown in the figure). When it is necessary to flush the second ultrafiltration membrane, the third flow path 33 communicates with the valve core inlet 21 and the first valve core outlet 22, and the fourth flow path communicates with the second valve core outlet 23 and the third valve core outlet.

[0044] In a preferred embodiment of the present application, the third flow path 33 connects the valve core inlet 21 and the second valve core outlet 23 , and the fourth flow path connects the first valve core outlet 22 and the third valve core outlet (not shown in the figure).

[0045] like Figures 1 to 9 As shown, in a preferred embodiment of the present application, when the integrated valve is in the first position, the first flow path 31 is connected, and when the turntable 3 rotates to the first position, the valve core inlet 21 of the valve core 2 is connected to the first valve core outlet 22 through the first flow path 31 of the turntable 3, and the valve core inlet 21 is connected to the second valve core outlet 23 through the second flow path 32.

[0046] The first valve core outlet 22 is connected to the first chamber 12 of the valve body 1. Then the fluid flows out to the outside through the first outlet 14 of the valve body 1, and the second valve core outlet 23 is connected to the second chamber 13 of the valve body 1, and then the fluid flows out to the outside through the second outlet 15 of the valve body 1. It should be noted that when the integrated valve is in the first position, the environment in which the integrated valve is used can be a state where the ultrafiltration membrane is in normal water production.

[0047] like Figures 1 to 9 As shown, in a preferred embodiment of the present application, when the integrated valve is in the second position, the second flow path 32 is connected, the turntable 3 rotates to the second position, the valve core inlet 21 is connected to the first valve core outlet 22 through the third flow path 33 of the turntable 3, and the second valve core outlet 23 is connected to the third valve core outlet through the fourth flow path. At this time, the first valve core outlet 22 is connected to the first chamber 12 of the valve body 1, and then the fluid flows out to the outside through the first outlet 14 of the valve body 1. The fluid then flows back to the second outlet 15 of the valve body 1 through the external pipeline, enters the second chamber 13, and then flows into the third valve core outlet through the second valve core outlet 23 through the fourth flow path of the turntable 3, flows into the third chamber of the valve body 1 through the third valve core outlet, and then discharges the fluid to the outside through the third outlet of the valve body 1. It should be noted that when the integrated valve is in the second position, it means that the environment in which the integrated valve is used is a state in which the second ultrafiltration membrane needs to be backwashed.

[0048] like Figures 1 to 9As shown, in a preferred embodiment of the present application, when the integrated valve is in the third position, the first flow path 31 and the second flow path 32 are conducted. The turntable 3 rotates to the third position. The valve core inlet 21 communicates with the second valve core outlet 23 through the third flow path of the turntable 3. The first valve core outlet 22 communicates with the third valve core outlet through the fourth flow path. At this time, the second valve core outlet 23 communicates with the second chamber 13 of the valve body 1, and then the fluid flows out to the outside through the second outlet 15 of the valve body 1. The fluid then flows back to the first outlet 14 of the valve body 1 through an external pipeline, enters the first chamber 12, and then flows into the third valve core outlet through the fourth flow path of the turntable 3 via the first valve core outlet 22. After flowing through the third valve core outlet, it flows into the third chamber of the valve body 1, and then the fluid is discharged to the outside through the third outlet of the valve body 1.

[0049] As Figure 1 shown, in a preferred embodiment of the present application, the integrated valve further includes a motor 4 and a gland 5. Among them, the gland 5 is arranged on the turntable 3. A fixing hole 34 adapted to the motor shaft (not shown in the figure) of the motor 4 is constructed on the turntable 3. The motor 4 is arranged on the gland 5. The motor 4 and the gland 5 are connected into one body through fasteners. A through hole 51 is constructed on the gland 5. The motor shaft of the motor 4 passes through the through hole 51 and can be inserted into the fixing hole 34. Among them, by the rotation of the motor shaft, the turntable 3 is driven to rotate. Specifically, after adding the motor 4 in the present application and passing the motor shaft of the motor 4 through the through hole 51 on the gland, and then inserting it into the fixing hole 34 on the turntable 3. It should be noted here that when the motor shaft is inserted into the fixing hole 34, the motor shaft and the fixing hole 34 are fixedly connected in the circumferential direction, that is, when the motor shaft rotates, the turntable 3 can be driven to rotate to achieve the purpose of switching different flow paths.

[0050] The above-mentioned "fasteners" can be bolts, screws or rivets, etc.

[0051] As Figure 1 shown, in a preferred embodiment of the present application, the gland 5 and the valve body 1 are fixedly connected into one body through fasteners to fix the turntable 3 and the valve core 2 between the gland 5 and the valve body 1. Specifically, by placing the valve core 2 on the upper end surface of the valve body 1, arranging the turntable 3 on the upper end surface of the valve core 2, arranging the gland 5 on the upper end surface of the turntable 3, passing the motor shaft of the motor 4 through the through hole 51 on the gland 5 and then inserting it into the fixing hole 34 on the turntable 3. Then, the motor 4 is connected to the valve body 1 as a whole using fasteners, and at the same time, the motor 4 is connected to the gland 5 as a whole using fasteners. In this way, the fixed installation of the entire integrated valve can be realized.

[0052] In a preferred embodiment of the present application, both the turntable 3 and the valve core 2 are made of hard materials. Specifically, the turntable 3 and the valve core 2 can rotate relative to each other to achieve the purpose of switching different flow paths, and due to the material, the function of mutual sealing between the turntable 3 and the valve core 2 can be realized.

[0053] In a preferred embodiment of the present application, the hard material includes ceramics.

[0054] In a preferred embodiment of the present application, the integrated valve further includes a seal (not shown in the figure) disposed between the valve core 2 and the valve body 1. The seal can seal each chamber of the valve body 1 and form independent chambers in the valve body 1 to connect with each valve core outlet of the valve core 2. Among them, the seal is preferably a silica gel gasket or a rubber gasket.

[0055] In a preferred embodiment of the present application, the turntable 3 can rotate relative to the valve core 2 to switch different flow paths. It should be noted that the turntable 3 can be driven by a motor 4, and at the same time, the turntable 3 can also be rotated manually.

[0056] As Figures 1 to 9 shown, in a preferred embodiment of the present application, the fourth flow path is configured as a waist-shaped groove 35. When the integrated valve is in the second position or the third position (backwashing state), the waist-shaped groove 35 will rotate to communicate with two adjacent valve core outlets in the valve core 2. It should be noted that there can be 5 ports on the valve core 2, one water inlet, two water outlets, and two wastewater outlets, and the two wastewater outlets can also be combined into one.

[0057] In each flushing state, the waist-shaped groove 35 on the turntable 3 will connect two through holes, so that the wastewater coming out of the valve core 2 flows to the wastewater chamber (not shown in the figure) and is discharged to the outside through the wastewater hole.

[0058] According to the second aspect of the present invention, there is also provided a water purification device including the above-mentioned integrated valve.

[0059] In summary, in the present application, a valve body inlet 11, a first chamber 12, a second chamber 13, a first outlet 14, a second outlet 15 and a third outlet are constructed on the valve body 1. At the same time, a valve core inlet 21 and at least three valve core outlets are constructed on the valve core 2. The first valve core outlet 22 of the valve core 2 communicates with the first chamber 12, the second valve core outlet 23 of the valve core 2 communicates with the second chamber 13, and the third valve core outlet communicates with the third chamber of the valve body. The valve core inlet 21 communicates with the valve body inlet 11. At the same time, a plurality of flow paths are respectively constructed on the turntable 3, and by rotating the turntable 3, the corresponding flow paths are made to communicate with the corresponding valve core inlets 21 and valve core outlets, so as to switch each flow path. It can be seen that by adding the integrated valve of the present application, the situation of using multiple valves simultaneously can be saved, and it has the advantages of small volume, low cost and high integration degree.

[0060] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
