Introduction Of The Working Principle Of Ball Valve
Jul 17, 2018

Ball valve, standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (spheres) driven by the stem, and revolving around the stem axis of the valve. It is mainly used to truncate or connect the medium in the pipeline, and can also be used to regulate and control the fluid. The hard sealed V ball valve has a strong shear force between the V core and the metal valve seat of the hardfacing hard alloy. It is especially suitable for the medium containing the fiber and the tiny solid material. The multi - ball valve can not only flexibly control the switching of the flow, shunt and flow of the medium, but also close any channel and connect the other two channels. Valves of this type should be installed horizontally in pipes. Classification of ball valves: pneumatic ball valves, electric ball valves and manual ball valves.


Working principle

The ball valve has the action of rotating 90 degrees, the cock body is a sphere, and a circular through hole or a passage passes through its axis. The ball valve is used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be closed with the operation of 90 degrees of rotation and a very small moment of rotation. The ball valve is most suitable for switching and shut-off valves, but the development of the ball valve has recently been designed to make it throttling and controlling flow, such as V ball valve.
