Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump valve that is convenient for controlling flow. Background Art

[0002] A water pump is a mechanical device that transfers liquid, usually water, from one place to another by creating a pressure difference. It is mainly divided into two types: centrifugal pumps and positive displacement pumps. It is widely used in households, buildings, agriculture and industry. Its uses include water supply, pumping, irrigation, drainage, circulation systems, etc., and it varies in types and sizes to meet different needs.

[0003] The flow control of current water pumps is relatively convenient during normal use, and can be adjusted by twisting the handle. However, there are deficiencies in subsequent adjustment after closing the valve. Closing the valve may cause water hammer effect of the water flow, which has a bad impact on the system. This is because the internal buffer of the current water pump is not sufficient. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a water pump valve which has good internal buffering effect of a valve body, can reduce water hammer effect, and is convenient for controlling flow.

[0005] In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a water pump valve that is convenient for controlling flow, comprising a valve body and a valve cover, wherein one side of the valve body is connected with a water inlet, and a water inlet buffer zone is provided near the water inlet, the other side of the valve body is connected with a water outlet, and a water outlet buffer zone is provided near the water outlet, a sealing structure is connected between the water inlet buffer zone and the water outlet buffer zone, the valve cover is connected to the valve body by bolts, a quantitative lifting structure is connected to the valve body and connected to the sealing structure, flow rate sensors are provided in the water inlet buffer zone and the water outlet buffer zone, a buffer concave zone is provided on one side of the water outlet buffer zone, and a buffer protrusion is connected on the other side.

[0006] Furthermore, the quantitative lifting structure includes a limiting ring connected to the valve cover, a lifting rod is rotatably provided in the limiting ring, a threaded rod is threadedly connected on the lifting rod, the threaded rod extends out of the valve cover and is connected to a rotating handle, a sealer is provided on the valve cover and located on the outside of the threaded rod, a pressure spring is provided between the lifting rod and the inner side of the valve cover, and a tightening valve plate is connected under the lifting rod.

[0007] Furthermore, the sealing structure includes an isolation plate connected to the valve body and located between the water inlet buffer zone and the water outlet buffer zone, a water hole is provided in the middle of the isolation plate, a sealing ring is connected to the water hole, and the sealing ring, the tightening valve plate and the sealing ring are in close contact.

[0008] Furthermore, an annular sealing gasket is filled in the limiting ring.

[0009] Furthermore, the flow rate sensor is electrically connected to an external digital display screen and a control device.

[0010] Furthermore, the lifting rod, the limiting ring and the tightening valve plate are all made of anti-corrosion materials.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Good buffering effect inside the valve body: The water inlet buffer zone and the water outlet buffer zone are set between the water inlet and the water outlet of the valve, and a sealing structure is set between the buffer zones. These buffer zones and sealing structures can slow down the water flow when it passes through, thereby achieving a certain buffering effect. In addition, structures such as buffer concave areas and buffer convex areas can also help further alleviate the impact force caused by the impact of water flow.

[0013] Can reduce water hammer effect: Water hammer effect refers to the pressure wave generated by the sudden closing or opening of water flow, which will cause impact and vibration inside the water pipe, causing damage to the pipes and equipment. The multiple buffer structure of the valve can effectively alleviate the water hammer effect, allowing the water flow to flow smoothly through the valve, thereby reducing the generation and propagation of pressure waves and protecting water pipes and equipment.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1A water inlet 3 is connected to one side of the valve body 1, and a water inlet buffer zone 4 is provided near the water inlet 3. A water outlet 5 is connected to the other side of the valve body 1, and a water outlet buffer zone 6 is provided near the water outlet 5. A sealing structure is connected between the water inlet buffer zone 4 and the water outlet buffer zone 6. The sealing structure includes an isolation plate 17 connected to the valve body 1 and located between the water inlet buffer zone 4 and the water outlet buffer zone 6. A water through hole is provided in the middle of the isolation plate 17. A sealing ring 18 is connected to the water through hole. The sealing ring 18 and the tightening valve plate 16 are in close contact with the sealing ring 18.

[0019] Combined with Figure 1 The valve cover 2 is connected to the valve body 1 by bolts. A quantitative lifting structure connected to the sealing structure is provided on the valve body 1. The quantitative lifting structure includes a limiting ring 10 connected to the valve cover 2. The limiting ring 10 is filled with an annular sealing gasket 19. A lifting rod 11 is rotatably provided in the limiting ring 10. The lifting rod 11, the limiting ring 10 and the tightening valve plate 16 are all made of anti-corrosion materials.

[0020] Combined with Figure 1 The lifting rod 11 is threadedly connected with a threaded rod 12, and the threaded rod 12 extends out of the valve cover 2 and is connected with a rotating handle 13. A sealer 14 is provided on the valve cover 2 and outside the threaded rod 12. A pressure spring 15 is provided between the lifting rod 11 and the inner side of the valve cover 2, and a tightening valve plate 16 is connected below the lifting rod 11. Flow rate sensors 7 are provided in the water inlet buffer zone 4 and the water outlet buffer zone 6, and the flow rate sensors 7 are electrically connected to the external digital display screen and the control device. A buffer concave area 8 is provided on one side of the water outlet buffer zone 6, and a buffer protrusion 9 is connected on the other side.

[0021] Specific implementation of the utility model: When the utility model is in use, the valve body 1 is connected to the pump body, and water enters from the water inlet 3 of the valve body 1. The water first flows through the water inlet buffer 4 to perform the first water flow buffering. If you want to control the water flow, you can turn the handle 13 by hand to rotate the threaded rod 12. When the threaded rod 12 rotates, it will drive the lifting rod 11 to move up, so that the pressing valve plate 16 and the sealing ring 18 are separated, so that the water outlet 5 can discharge water. The height of the lifting of the pressing valve plate 16 determines the water outlet speed of the water outlet 5. The limit ring 10 ensures that the lifting rod 11 is lifted. The lowering process is stable, the pressure spring 15 prevents the limit ring 10 from shifting, the annular sealing gasket 19 and the sealer 14 ensure that no water enters the valve cover 2, thereby extending the service life. The water outlet buffer zone 6 plays a secondary buffering role. When the valve plate 16 and the sealing ring 18 are tightly pressed against each other, the water in the valve body 1 will continue to flow out from the water outlet 5. At this time, the water rushes into the buffer recess 8 under the outer contour of the buffer protrusion 9, and performs three buffering operations, so that the water that finally flows out is stable and the water hammer effect is avoided. The speeds of water inlet and outlet are monitored by the corresponding flow rate sensor 7 and transmitted to the external equipment for display.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
