Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, and specifically to a ball valve with a sewage discharge structure. Background Art

[0002] A ball valve is a valve in which the closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, the hard-sealed V-type ball valve has a strong shearing force between its V-type ball core and the metal valve seat with surfacing hard alloy, and is particularly suitable for media containing fibers, tiny solid particles, etc. 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 to connect the other two channels. Generally, this type of valve should be installed horizontally in the pipeline. The ball valve is divided into: pneumatic ball valve, electric ball valve, and manual ball valve according to the driving method;

[0003] When the ball valve is in the closed state, impurities are likely to precipitate and accumulate at the position of the closing member. Excessive accumulation of impurities will form calcified scale and accumulate in the inner cavity of the valve body, which will affect the normal operation of the valve. Therefore, the present invention proposes a ball valve with a sewage discharge structure to solve the above problems. Summary of the Invention
