The pneumatic ball valve is flexible. Ball and valve seat rings are metal materials, sealing pressure than the large, rely on the media itself can not seal the pressure requirements be imposed by external forces. The valve for high temperature and pressure medium.
Elastic sphere is open in the sphere of a flexible bottom wall slot, and access flexibility. When the closed channel, the wedge-shaped head with a stem to open up the ball and pressed to seal the valve seat. Wedge-shaped head off before the sphere in rotation, Sphere will restore the original shape, so that there is a small gap between the spheroid and valve seat, the sealing surface can reduce the friction and operating torque.
Pneumatic valve position according to their channels can be divided into straight-through, three-and right-angle type. Distribution medium for the latter two ball and change the flow of media. Operation and use of
1) To be confirmed before operation the pipe and valve has been washed.
2) The operation of the valve by rotating the valve rod the size of the input signal of the executive body: 1/4 (900) of positive rotation, the shut-off valve. Counter-rotating 1/4 (900), the valve is open.
3) As the executive body when the arrow direction parallel and pipeline, valve is open; Arrow and vertical pipelines, valves to shut down.
Has long service life and maintenance-free period will depend on the following factors: normal working conditions, to maintain harmony and temperature/pressure ratio, and the reasonable corrosion data.
