Standard pneumatic ball valve structure

Date:2014/7/28From:Zhongcheng Valve Group Co., Ltd

A, anti-static function:

in A sphere, the valve stem and valve body between spring, will be generated switching process of electrostatic export.Enforcement agencies;

B, the valve stem seal is reliable, due to the valve stem will only be used as the rotation without lifting movement, the valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases;

C, seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and the ball valve seal ability increases as the medium pressure increases;

D, thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation;

E, such as ptfe material has good self-lubrication, with ball friction loss is small, so the ball valve's service life is long;

F, bottoms valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the stem seal;

G, small fluid resistance, ball valve is the smallest of all valve fluid resistance in the class a, even reducing ball valve, the fluid resistance is small.Pneumatic ball valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, in the above aspects and similar valve, by contrast, the advantage!
