Ball valve convenient to overhaul
Technical Field
The utility model relates to a ball valve technical field specifically is a ball valve of convenient maintenance.
Background
Ball valves (ball valve is a stop valve in the marine and marine fields), defined in standard GB/T21465-2008 "valve nomenclature" as valves in which the closure member (ball) is carried by a valve stem and rotates about the axis of the ball valve. The hard seal V-shaped ball valve can also be used for regulating and controlling fluid, wherein a V-shaped ball core of the hard seal V-shaped ball valve and a metal valve seat of the build-up welding hard alloy have strong shearing force, and the hard seal V-shaped ball valve is particularly suitable for media containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The valve of this type should be generally installed horizontally in the pipeline. Ball valve classification, including pneumatic ball valve, electric ball valve and manual ball valve.
Some ball valves on the existing market are most bolted connection modes because the detachable connection between the side face of the ball valve body and the pipeline structure leads to the need of overhauling the ball valve, the disassembly and installation are very complicated, the operation efficiency is relatively troublesome and influenced, impurities possibly mixed when the fluid flows through in the ball valve do not have a good impurity filtering function, and the blockage is easily caused.
We have therefore proposed a ball valve which is easy to service in order to solve the problems set out above.
