The use and function of ball valve

Use of ball valve:
According to the structure, ball valves can generally be divided into three categories: floating ball valves, fixed ball valves and elastic ball valves. According to different sealing performance, it can be divided into hard sealing ball valve and soft sealing ball valve, among which soft sealing ball valve has better sealing performance and can achieve zero leakage. It is generally used for normal temperature and normal pressure pipelines with corrosive media, while hard-sealed ball valves can be used not only in normal temperature and normal pressure, but also in low temperature and low pressure and high temperature and high pressure pipelines.
The role of the ball valve:
The ball valve opening and closing part is a round sphere with a hole, which uses the ball core to rotate 0-90° back and forth around the axis of the valve stem to open or close the valve. There are many functions of the ball valve, generally used to cut off or adjust the medium in the pipeline, among which the three-way ball valve can flexibly cut off, distribute and change the flow direction of the medium. The sealing surface of the ball valve is usually in a closed state with the spherical surface, which is not easy to be corroded by the medium. The operation is convenient, the structure is simple and compact, and it can be used in the presence of water, natural gas, acid, solvent, etc.
Other common classification of ball valves, chip ball valve, orbital ball valve, V-type ball valve, O-type ball valve, globe ball valve, three-way ball valve, four-way ball valve, forged steel ball valve, ash discharge ball valve, anti-sulfur ball valve, eccentric ball valve, insulation ball valve, pneumatic Ball valve, electric ball valve, ferrule ball valve, welded ball valve. Among them, the V-shaped ball valve has a shearing effect, and is especially suitable for media containing fibers, tiny solid particles, and slurries. Three-way ball valve can also be divided into T type and L type. The t-shape can connect three intersecting pipes to each other or cut off any one of the channels, and start splitting and merging with action. The L-shaped pipe only connects two pipes that are perpendicular to each other, and cannot connect a third pipe at the same time. main distribution effect.
