A quick shut-off valve for a water pump service connection

Abstract

The invention discloses a quick turn-off valve for water pump operation connection. The quick turn-off valve comprises a valve shell, wherein a liquid inlet pipe and a liquid outlet pipe are arrangedon two sides of the valve shell, a first-stage liquid inlet turn-off assembly is arranged in the middle part of the outer wall of the top end of the liquid inlet pipe, the middle part of the outer wall of the top end of the liquid outlet pipe is provided with a first-stage liquid outlet turn-off assembly, and the first-stage liquid outlet turn-off assembly and the first-stage liquid inlet turn-offassembly are the same in structure; three sliding blocks are uniformly distributed in a cylinder hole of the valve shell, a first valve body are coaxially connected between two adjacent sliding blocks, and a second valve body are coaxially connected between two adjacent sliding blocks; and a screw rod is fixedly connected to the top surface of the sliding block positioned above, a threaded section of the screw rod is spirally arranged at a threaded hole in the middle part of the top plate of the valve shell; and a handle is fixedly connected to the top end of the screw rod. The quick turn-offvalve has the advantages that use is rapid, efficient and convenient, water path opening and closing efficiency in the water pump operation can be greatly improved, and the quick turn-off valve is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of water valves, and in particular relates to a quick shut-off valve used for the operation connection of water pumps. Background technique [0002] Valves are used in fluid control systems, ranging from the simplest globe valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves and other valve materials according to the material. [0003] At present, valves are often used in the operation of water pumps; they can open and close the working waterway; ...

AI Technical Summary

Problems solved by technology

[0003] At present, valves are often used in the operation of water pumps; they can open and close the working waterway; however, the valves used in existing water pumps respond slowly when opening and closing, and cannot meet the requirements of the site, especially when they need to be cut off quickly. In the special case of the waterway, it is particularly important to design a valve that can quickly shut off the waterway
