Background

The ball valve can be applied to industries such as petroleum, natural gas, chemical industry, metallurgy, medicine, electric power and the like, and is a valve in which a ball body is driven by a valve rod and rotates around the axis of the ball valve. The device can also be used for regulating and controlling fluid, wherein the hard seal V-shaped ball valve has strong shearing force between the V-shaped ball core and the metal valve seat of the hard alloy for surfacing, and is particularly suitable for mediums containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the flow direction switching of the medium on the pipeline, and simultaneously can close any channel to connect the other two channels.

The input and output ends of the existing ball valve are welded on the pipeline generally, when the ball valve is damaged, the input and output ends of the ball valve can be detached after being disconnected with the pipeline, then the input and output ends of the ball valve are welded on the pipeline after a new ball valve is replaced, the replacement steps are complex, the disassembly and maintenance are inconvenient, and the disassembly efficiency is low.

Therefore, we propose a ball valve which can be disassembled and overhauled on line quickly to solve the problems.
