Ball valve with pressure relief function

Abstract

The invention discloses a ball valve with a pressure relief function. The ball valve comprises a ball valve body, the outer surface of the ball valve body is fixedly connected with a first threaded connector, the outer surface of the first threaded connector is in threaded connection with a piston barrel, and the lower portion of the outer surface of the piston barrel is fixedly connected with a second threaded connector. An inner cavity of the second threaded connector is in threaded connection with a pressure gauge, a pressure discharging device is fixedly connected to the outer surface of the piston barrel, a piston device is installed in an inner cavity of the piston barrel, and an adjusting device is fixedly connected to the upper end face of the piston device. The invention relates to the technical field of ball valves with the pressure relief function. According to the ball valve with the pressure relief function, the problems that due to the fact that a traditional ball valve is inconvenient to install and detach during pressure relief, later maintenance is inconvenient, the maintenance cost is high, and meanwhile the ball valve is likely to be damaged are solved.

Description

technical field [0001] The invention relates to the technical field of ball valves with pressure relief function, in particular to a ball valve with pressure relief function. Background technique [0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. According to the driving mode, the ball valve is divided into: pneumatic bal...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a ball valve with pressure relief function, which solves the problem of inconvenient installation and disassembly of the traditional ball valve during pressure relief, which leads to inconvenience and high maintenance cost in the later stage, and also easily causes damage to the ball valve. question
