Analysis the characteristics of high temperature pneumatic ball valve (1)

overview of the characteristics of high temperature ball pneumatic valve:
by the characteristics of high temperature pneumatic ball valve, pneumatic valve seat soft of multilayer T sealing ring on both sides of the stainless steel sheet.
high temperature of the pneumatic valve pneumatic ball valve plate and pneumatic valve seat sealing surface for the oblique cone structure, oblique cone surface in pneumatic valve of tubesheet heat resistance, corrosion resistant alloy material; Between the ring plate of steel plate spring and adjusting screw on assembly structure adjustment. This structure effectively compensation between the collar and pneumatic valve stem in the central and elastic deformation under pressure, to solve the sealing problems in communication in the process of the transmission medium of two ventilation valve tolerance.
high temperature and soft T - Sealed on both sides of multi-layer stainless steel sheet with metal sealing and soft sealing both low and high temperature under the condition of double advantage, all with zero leakage, sealed performance is good, pneumatic ball valve. Trials show that pool is flow state ( The medium flow direction at the same rotating direction) , the sealing surface pressure is medium pressure and torque transmission effect of pneumatic valve plate. Positive media pressure pneumatic valve plate oblique cone surface and pneumatic valve seat sealing surface squeezed tight, sealing the better the results.
when the counter of the state, high temperature pneumatic ball valve plate between the driving moment of pneumatic valve plate to the pneumatic seat seat tightness. As reverse medium pressure, pneumatic valve plate and the positive pressure pneumatic seat between units is less than the medium pressure, depending on the load adjusting ring in the spring, to make up for in to the pressure of pneumatic valve plate and seat stored in the sealing surface deformation by automatic compensation effect.
so the utility model is not like the existing technology, in the pneumatic valve plate installed on the hard and soft multi-layer sealing ring, but is installed directly on the body, in the middle of the clamp and pneumatic seat add adjustable ring is a two-way sealed very good method. It can replace the pneumatic valve, pneumatic ball valve.
