A water pipeline valve with decompression and damage prevention

Abstract

The invention relates to the field of water pipeline valves, in particular to a water pipeline valve with decompression and damage prevention, including a valve body, a water inlet and outlet structure, a control structure, a limit structure, a protection structure, an alarm structure and a lubrication structure; Through the setting of the water inlet and outlet structure, the valve body can be installed and connected with the external water pipe, and the water entering the valve body can be filtered again to prevent scale from entering the valve body, thereby prolonging the service life of the valve body. And through the setting of the control structure, it can not only play the role of controlling the flow of water inside the valve body, but also play a role of protection, and the rotation mode of the control structure is set on the side wall of the valve body, which can make the valve body suitable for some Narrow space, and through the setting of the limit structure, it can play the role of limit when the control structure needs to be fixed, so as to avoid the automatic rotation of the control structure.

Description

technical field [0001] The invention relates to the field of water delivery pipeline valves, in particular to a water delivery pipeline valve capable of reducing pressure and preventing damage. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off 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 typ...

AI Technical Summary

Problems solved by technology

[0003] Valves are usually installed on the water pipeline in order to control the on-off of the water flow conveniently, but because the current valves generally do not have the function of decompression, when the water pressure inside the water pipeline is too large, it is easy to If the valve body is damaged, and when the water pressure inside the water pipeline is abnormally high, it is not easy for the maintenance personnel to detect it, which may cause the pipeline to rupture.
