Pressure relief controlling regulating valve with pressure capable of being visible

Abstract

The invention provides a pressure relief controlling regulating valve with pressure capable of being visible. The pressure relief controlling regulating valve comprises an upper valve body and a lower valve body, wherein the upper valve body and the lower valve body are fixedly connected; an isolation plate is arranged in the middle of lower valve body; a portion, connected with a left connecting opening and a right connecting opening, of a cavity is divided into two independent cavities by the isolation plate; the position, below an upper connecting opening of the lower valve body, of the isolation plate is of a horizontal structure; a water flowing hole facing the upper connecting opening directly is arranged on the horizontal position of the isolation plate; an outer pressure valve element capable of sliding up and down is installed inside an installing hole of the upper valve body; an inner regulating valve element is installed in the middle of the outer pressure valve element in a sliding and sealing mode; the water flowing hole is a cylindrical hole; the lower portion of the inner regulating valve element and the water flowing hole are assembled in a sliding and sealing mode; and the inner regulating valve element is connected with a pipe thread in a threaded mode. When the valve is in use, the water pressure inside the lower valve body can be convenient to observe for people through a lower scale of the outer pressure valve element. The quantity of pressure relief can be adjusted by adjusting the height of the inner regulating valve element.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a pressure-visual pressure relief control regulating valve. Background technique [0002] Valves can be used to control the on-off of flowing liquid. According to different control structures and control purposes, valves can be divided into many types. The pressure relief valve, also known as the safety valve, can automatically open and close according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, it will automatically open the pressure relief to ensure that the medium pressure in the equipment and pipeline is below the set pressure, protect the equipment and pipeline, and prevent accidents. In many systems, the pressure in the pipeline can be observed in time, and a speci...

Problems solved by technology

Traditional valves cannot change the pressure relief value, so it is necessary to replace valves with different specifications, and the operation is relatively cumbersome
