Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump sealing valve. Background Art

[0002] A water pump is a mechanical device used to transport liquid, usually water, from one place to another. A water pump draws in liquid by creating a vacuum or using mechanical pressure, and achieves transportation by discharging the liquid. Water pumps are commonly used in industrial, agricultural, construction and household applications. Common types include centrifugal pumps, plunger pumps, screw pumps, etc. Water pumps play an important role in irrigation, drainage, water supply, heating, air conditioning and other fields.

[0003] Most water pumps on the market currently have good sealing performance, but the filtering effect is not ideal. Although the sealing valve can play a preliminary filtering role, in most cases, it is still necessary to rely on the filter to achieve further filtration. However, for water sources containing high impurities, the filter is often easily blocked, and cleaning and replacing the filter is relatively cumbersome. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a water pump sealing valve which is convenient for cleaning the filter screen in the valve body and suitable for use in water sources with large impurities.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a water pump sealing valve, comprising a valve body and an upper cover, the upper cover is detachably arranged on the valve body, a water outlet is arranged on one side of the valve body, and a water inlet is arranged on the other side, a side pipe is sealingly connected to the water inlet, a bottom inlet is arranged below the side pipe, a detachable filter is connected to the water inlet, a circular plate is slidingly arranged in the side pipe, a sealing ring that is in close contact with the side pipe is connected to the outer ring of the circular plate, a waterproof motor is connected to the outer side of the circular plate, the output end of the waterproof motor passes through the circular plate, and a circular brush is drivingly connected, a position limiting structure that prevents the sealing ring from moving is connected between the side pipe and the waterproof motor, a sewage pipe is connected below the valve body, and a switch valve for controlling sewage discharge is provided on the sewage pipe.

[0006] Furthermore, the upper cover and the valve body are connected by bolts, and a spiral sealing structure extending into the valve body is provided in the upper cover.

[0007] Furthermore, the spiral sealing structure includes a threaded rod rotatably arranged in the upper cover, a sealing water baffle is provided in the valve body, a lifting rod is connected to the sealing water baffle and threadedly connected to the threaded rod, and a round handle with anti-slip patterns is connected to the threaded rod.

[0008] Furthermore, the position limiting structure includes a bending rod connected to the outside of the waterproof motor, a guide groove is provided on the side tube, reserved holes are provided on both sides of the guide groove, a slider is provided for sliding in the guide groove, and a positioning bolt is provided that passes through the bending rod and the slider and is inserted into the reserved hole.

[0009] Furthermore, the side pipe and the water inlet are connected by bolts.

[0010] Furthermore, a blocking ring for blocking the sealing ring is connected to one side of the side tube.

[0011] Furthermore, a sealed bearing is provided between the circular plate and the output end of the waterproof motor.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] Reasonable filter design: The filter of this technical solution is located at the water inlet, and a bottom inlet is provided under the side pipe. When the filter needs to be cleaned, just close the sealing baffle, remove the positioning bolt, and push the slider to slide in the guide groove so that the circular plate slides in the side pipe and touches the filter. Compared with other types of water pumps, the steps for cleaning the filter are simpler and clearer.

[0014] Circular brush cleaning: This technical solution also designs a circular brush, which is located at the output end of the waterproof motor connected to the outside of the circular plate. It can break up and remove impurities on the filter screen, effectively ensuring the service life and performance of the water pump.

[0015] Bottom drain pipe: The bottom inlet of this technical solution discharges water and impurities through the drain pipe, avoiding the problem of impurities entering the water pump again during the cleaning process, greatly improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Combined with Figure 1 and attached Figure 2 The upper cover 2 is detachably arranged on the valve body 1. A water outlet 3 is arranged on one side of the valve body 1, and a water inlet 4 is arranged on the other side. A side tube 5 is sealed and connected at the water inlet 4. A bottom inlet 6 is arranged below the side tube 5. A detachable filter screen 7 is connected at the water inlet 4. A circular plate 8 is slidably arranged in the side tube 5. A sealing ring 9 that is in close contact with the side tube 5 is connected to the outer ring of the circular plate 8. A waterproof motor 10 is connected to the outer side of the circular plate 8. The output end of the waterproof motor 10 passes through the circular plate 8, and a circular brush 11 is provided for driving connection. A position limiting structure that prevents the sealing ring 9 from moving is connected between the side tube 5 and the waterproof motor 10. The position limiting structure includes a bending rod 18 connected to the outer side of the waterproof motor 10. A guide groove 19 is arranged on the side tube 5. Reserved holes 20 are arranged on both sides of the guide groove 19. A slider 21 is slidably arranged in the guide groove 19. A positioning bolt 22 is provided that passes through the bending rod 18 and the slider 21 and is inserted into the reserved hole 20.

[0021] Combined with Figure 2 A sewage pipe 12 is connected to the bottom of the valve body 1, and a switch valve 13 for controlling sewage discharge is provided on the sewage pipe 12. The side pipe 5 and the water inlet 4 are connected by bolts. A blocking ring 23 for blocking the sealing ring 9 is connected to one side of the side pipe 5.
