Hard seal ball valve applicable occasions?
In eccentric metal hard seal ball valve sealing structure and sealing for the metal to metal seal, can exchange the metal sealing ring to metal seal, stainless steel plate and graphite composite plate sealing ring to metal seal.Hard seal butterfly valve drive form except electric are: manual, worm gear drive, pneumatic, etc.The average valve.
Hard seal butterfly plate installed on the diameter of the pipe direction of the ball valve.Within the cylindrical passage hard seal ball valve body, disc disc around the axis of rotation, rotation Angle for 0 ° ~ 90 °, rotate to 90 °, the valve is fully open.New high life features of stainless steel butterfly valves and butterfly valves in the process of using existing problems at present, hard seal butterfly valve as a hard seal ball valve is used to realize on-off and flow control components, piping system has been used in petroleum, chemical industry, metallurgy, water and electricity is widely used in many fields such as extremely.In butterfly valve technology has been known, its seal form with seal structure, sealing materials for rubber, ptfe, etc.Because of the limitation of structural features is not adapt to the high temperature, high pressure and corrosion resistance, wear resistance, etc.
Existing a more advanced butterfly valve is a triple eccentric metal hard seal butterfly valve, the valve body and seat for the Siamese components, valve seat sealing surface layer welding temperature resistant, corrosion resistant alloy material.Multilayer soft fold type sealing ring is fixed on the valve plate, the butterfly valve and the traditional butterfly valve compared with high temperature resistant, convenient operation, opening and closing without friction, closed as the actuator torque increases to compensate for sealing, improve the butterfly valve sealing performance and prolong the service life of the advantages.
That is about hard seal ball valve applicable occasions related introduction, hope can help to you.
