Description

Technical Field

[0001] This utility model relates to the field of pump and valve technology, specifically to a corrosion-resistant pump and valve. Background Technology

[0002] Pumps and valves are commonly used for conveying fluids, controlling flow, and diverting and merging flows. Pumps transport fluids from one place to another through rotation, vibration, or compression. Whether it is a liquid or a gas, pumps help meet the needs of industrial production and people's lives. Valves are key devices for controlling fluid flow; they can open, close, or regulate the flow rate of fluids in pipelines, thereby achieving flow control and regulation.

[0003] For example, Chinese patent application CN202222082410.8 discloses a corrosion-resistant pump valve, the specific content of which is as follows: after the lateral part of the L-shaped connecting plate is vertically aligned with the connection port, the protective cover is moved downward, allowing the lateral part of the L-shaped connecting plate to pass through the connection port. Finally, the hands holding the handle are released, at which point the compression spring will perform a restoring extension operation, forcing the lateral part of the L-shaped connecting plate to move downward and outward towards the connection port, thereby allowing the protective cover to be locked onto the protective shell. This is to use the protective shell and the protective cover to protect the pump valve body. However, it still has the following technical problems:

[0004] The pump valve body is protected by a protective mechanism and a protective shell. However, during the use of the pump valve, the operation of removing the protective cover is too cumbersome, making it difficult to quickly open and close the pump valve. Utility Model Content

[0005] Therefore, this utility model provides a corrosion-resistant pump valve to solve the problem that existing technologies make it difficult to quickly open and close pump valves.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A corrosion-resistant pump valve, comprising a pump valve body.

[0008] The pump valve body is equipped with a protective component 1 and a protective component 2 for protecting the pump valve body. The protective component 2 is installed on the top of the pump valve body, and the protective component 1 is installed on the bottom of the pump valve body.

[0009] The upper end of the pump valve body is equipped with a first handwheel for opening and closing the pump valve body, and the lower end of the first handwheel is equipped with a transmission component.

[0010] The second protective component includes a second bevel gear for cooperating with the transmission component to control the rotation of the first handwheel. The second bevel gear includes a second handwheel for controlling the rotation of the second bevel gear, and the second handwheel is mounted on the outside of the second protective component.

[0011] Furthermore, the first handwheel has multiple limiting holes in its middle section, and a positioning hole is also provided in the middle section of the first handwheel.

[0012] Furthermore, the transmission assembly includes a first bevel gear, the upper end of which is equipped with a plurality of screws for limiting a pair of the first bevel gears by cooperating with limiting holes, and the upper end of the screws is equipped with nuts.

[0013] Furthermore, the protective component one includes a first protective shell, with limiting holes two at both the front and rear ends of the first protective shell, and mounting grooves are provided above the front and rear ends of the first protective shell, with a sealing gasket installed in the groove cavity of the mounting groove.

[0014] Furthermore, the second protective component includes a second protective housing, the upper end of which is equipped with a positioning block for positioning the second protective housing in conjunction with a positioning hole, and bolts are installed at the front and rear ends of the second protective housing.

[0015] Furthermore, a rotating rod is mounted on one end of the second bevel gear, and a second handwheel is mounted on the right end of the rotating rod.

[0016] This utility model has the following advantages:

[0017] With the second handwheel, when controlling the opening and closing of the pump valve body, only the second handwheel needs to be rotated. The rotating rod synchronously drives the second bevel gear to rotate, and the second bevel gear, in conjunction with the first bevel gear, drives the first handwheel to rotate, thereby opening and closing the pump valve body. The first and second protective components of this utility model protect the pump valve body, and the first handwheel can be controlled to open and close the pump valve body by rotating the second handwheel, making the operation simple and quick.
