Problems solved by technology

This requires a good control of the pressure in the pipeline. When the pressure in the pipeline is too high, if the pipeline is continuously pressurized, it will cause impact on the pipeline and cause a pipe burst accident, which will affect the safety of transportation. This requires a A valve that can control the pressure of the fluid in the pipeline to control the pressure of the pipeline
Most of the existing pressure stabilizing valves use electric control to control the flow and velocity, which has complex structures, cumbersome control procedures and high manufacturing costs.

Abstract

The invention discloses a voltage regulation protection valve, which comprises a valve body and a cover plate, wherein the valve body is fixedly connected with the cover plate, and a liquid inlet, a liquid storage cavity and a liquid outlet are arranged on the valve body; and the liquid inlet is communicated with the liquid outlet through a liquid inlet channel and the liquid storage cavity. The voltage regulation protection valve is characterized in that the valve body and a bottom cover are fixedly connected and are sealed by a sealing piece, and a spring is arranged in the bottom cover; one end of the spring is connected with the bottom cover, and the other end of the spring is propped against a spring seat; and a pull rod is connected onto the spring seat, penetrates through the sealing piece and is also connected with a sealing plug, and the sealing plug and the liquid inlet channel are sealed. The voltage regulation protection valve provided by the invention has the characteristics of simple structure and low production cost.

Description

technical field [0001] The invention relates to a valve, in particular to a pressure stabilizing protection valve for stabilizing medium flow. Background technique [0002] At present, during the transportation of fluids, pipeline connections are used for transportation. This requires a good control of the pressure in the pipeline. When the pressure in the pipeline is too high, if the pipeline is continuously pressurized, it will cause impact on the pipeline and cause a pipe burst accident, which will affect the safety of transportation. This requires a A valve that can control the pressure of the fluid in the pipeline is used to control the pressure of the pipeline. Most of the existing pressure stabilizing valves use electric motors to control the flow and velocity, and their structures are complex, the control procedures are cumbersome, and the manufacturing cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a pressure ...
