Abstract

The invention discloses a voltage regulation valve, which comprises a valve body, wherein a liquid inlet and a liquid outlet are arranged in the valve body, and a spool is arranged in the valve body. The voltage regulation valve has the innovative points that the liquid inlet and the liquid outlet in the valve body are vertically communicated with each other, and the top end of the valve body is fixedly connected with an upper cover; a baffle is arranged at the liquid inlet of the valve body, and a tapered hole is arranged in the baffle; the inner surface of the upper cover is propped against one end of a spring, and a spring seat is also arranged in the valve body; the other end of the spring is propped against the spring seat, and the spring seat is fixedly connected with the spool through a connecting rod; and the spool is a frustoconical body and slides in the tapered hole, and the diameter D of the lower bottom surface of the frustoconical body is greater than the small inner diameter d1 of the tapered hole and is smaller than the large inner diameter d of the tapered hole. The voltage regulation 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 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 stabilizing...
