Hard seal worm gear adjustment characteristics of pneumatic valve

and hard seal turbine butterfly pneumatic valve seal is to use soft layer of metal transfer, through high precision machinery processing and forming, embedded in a disc plate is consistent with the pneumatic valve seat, with metal sealing and the double advantage of elastic sealing, no matter under the condition of low temperature and high temperature, has good sealing property.
, using three-dimensional structure of eccentric pneumatic seat and disc plate almost frictionless, have the close tight sealing function.
and unique structure, flexible operation, energy saving, convenient and not affected by medium pressure high, low, reliable sealing performance, long service life.
and hard seal turbine control adjusting device, pneumatic valve is equipped with the seal after long-term use if seal performance degradation, adjustable disc plate sealing ring to be near pneumatic valve seat can restore original sealing performance, greatly improve the service life.
