Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a multi-functional water pump control valve, including a valve body 1 and a valve cover. The two sides of the valve body 1 are respectively provided with a water inlet 2 and a water outlet 3. A filter component 4 is arranged inside the water inlet 2. The filter component 4 is arranged in an annular groove on the inner side wall of the valve body 1. An installation cylinder 401 is slidably connected inside the annular groove. A buffer groove is provided on the inner side wall of the installation cylinder 401. A sliding ring 402 is slidably connected inside the buffer groove. A connecting ring is fixedly installed on the inner side wall of the sliding ring 402. A nylon filter mesh bag 403 is fixedly installed on the inner side wall of the connecting ring. A plurality of buffer springs 404 are fixedly installed in an annular array on one side surface of the sliding ring 402. The other end of the buffer spring 404 is fixedly installed on the inner side wall of the buffer groove. A plurality of guide posts 405 are slidably penetrated and connected inside the sliding ring 402. The guide posts 405 are fixedly installed on the inner side wall of the buffer groove. A clamping cylinder 406 is fixedly installed on one side surface of the connecting ring. The clamping cylinder 406 is slidably connected to the inner side wall of the installation cylinder 401.

[0024] When the filtering component 4 is installed inside the annular groove of the water inlet 2, the installation cylinder 401 is slidably installed inside the annular groove, and the water flow passes through the surface of the nylon filter bag 403, filtering the impurities inside the water flow into the nylon filter bag 403. When the nylon filter bag 403 is subjected to an impact force, the sliding ring 402 is driven to slide to one side through the connecting ring. The sliding ring 402 stably slides on the outer surface of the guiding column 405, and at the same time, it will squeeze the buffer spring 404 on one side. Most of the impact force of the water flow is absorbed by the buffer spring 404, ensuring the normal operation of the device, greatly reducing the wear and damage to the water pump and valve, and then extending the service life of the multi-functional water pump control valve.

[0025] For the quick installation of the filtering component 4, as Figure 1 shown in Figure 2 , a docking groove is provided on the side surface of the installation cylinder 401. A clamping ring 5 is slidably connected inside the docking groove. A threaded ring is fixedly installed on one side surface of the clamping ring 5. A threaded groove is provided on the inner side wall of the water inlet 2. The threaded groove is adaptively connected to the threaded ring. A sealing ring 6 is fixedly installed on one side surface of the threaded ring. A flange is provided on the outer surface of the water inlet 2.

[0026] Rotate the threaded ring inside the threaded groove to drive the clamping ring 5 on one side to move. The clamping ring 5 rotates and moves synchronously, so that the clamping ring 5 is inserted into the docking groove on one side of the installation cylinder 401, thus completing the installation operation of the filtering component 4. At the same time, the setting of the sealing ring 6 on one side ensures the sealing performance during pipeline connection.

[0027] To form a turbulent flow and reduce the impact on the filtering component 4, as Figure 1 shown in

[0028] , clamping shafts are provided on both the upper and lower side walls of the installation cylinder 401. A water blocking plate 7 is rotatably connected to the outer surface of the clamping shaft. A clamping column is fixedly installed on one side surface of the two water blocking plates 7. A connecting member is fixedly installed on the outer surface of the clamping column. A titanium alloy spring 8 is connected between the two connecting members. The distance between the upper and lower water blocking plates 7 is relatively small, which can make the water flow form a turbulent flow, increasing the contact area between the water flow and the nylon filter bag 403, improving the filtering efficiency of the nylon filter bag 403. At the same time, the water blocking plate 7 can reduce the impact force of the water flow directly on the nylon filter bag 403, improving the service life of the nylon filter bag 403. The water blocking plate 7 will rotate after being subjected to an impact force to flexibly block the water flow. The titanium alloy spring 8 will control the rotation range of the water blocking plate 7 and will reset when there is no impact force.

[0029] In order to improve the sealing performance of the slow-closing valve core 10 and protect the bottom of the slow-closing valve core 10, a valve seat 9 is arranged inside the valve body 1. A support ring is arranged on the inner side wall of the valve seat 9. The slow-closing valve core 10 is slidably connected inside the valve seat 9. A valve stem 11 is fixedly installed inside the slow-closing valve core 10. A sealing layer 12 is arranged on the outer surface of the slow-closing valve core 10. A rubber ring 13 is arranged on the lower surface of the slow-closing valve core 10. A diaphragm is arranged on the outer surface of the valve stem 11. Both sides of the outer surface of the valve body 1 are connected with a regulating valve through pipelines. The other end of the regulating valve is connected to the surface of the valve body 1 through a pipeline.

[0030] During the long-term use of the slow-closing valve core 10, certain wear will occur. The rubber ring 13 at the bottom contacts the valve seat 9, reducing the loss during the use of the slow-closing valve core 10. The sealing layer 12 closely adheres to the inner side wall of the valve seat 9, and the sealing layer 12 on the peripheral side improves the sealing performance of the slow-closing valve core 10 when it is closed.

[0031] A guiding slide hole is formed on the lower surface of the valve stem 11. A column 14 is slidably connected inside the guiding slide hole. A stabilizing frame 15 is fixedly installed on the outer surface of the column 14. Both the stabilizing frame 15 and the column 14 are fixedly installed on the inner bottom wall of the valve body 1.

[0032] During the movement of the valve stem 11, it slides on the outer surface of the column 14. The column 14 is fixedly installed on the inner bottom wall of the valve body 1 through the stabilizing frame 15. The movement trajectory of the valve stem 11 is guided by the column 14, improving the stability of the valve stem 11 during movement, avoiding the situation of deviation, and ensuring the operation stability of the device.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
