half of an eccentric valve is equipped with a floating valve seat. Under the pressure of medium, the seat move, make the seal tightly pressed on the sphere, guarantee the seal. Half of an eccentric valve is usually mounted on the upper and lower axis of the ball bearing, the operating torque is small, suitable for high pressure, large diameter valves. To reduce the work of the ball valve torque and improve the reliability of seals, the oil seal ball valve in recent years. Special lubricating oil injection between eccentric ball valve sealing surface, forming oil film. Fixed ball valve not only improve the sealing performance, and reduce the working torque. More suitable for the high pressure large diameter ball valve. In known butterfly valve, the half of an eccentric valve seal form mostly adopts the sealing structure, sealing materials for rubber, ptfe, etc. , because of the limitation of structural features is not suitable for high temperature and high pressure, etc. Corrosion resistance, abrasion resistance. More advanced butterfly valve is three and a half eccentric ball valve. Valve body and valve seat for fitting, the eccentric half ball valve sealing surface covered with a heat resistance, corrosion resistant alloy material. Half of an eccentric valve multilayer soft interlayer sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve with high temperature resistant, convenient operation, opening and closing without friction, etc. In closing, by increasing the output torque of the driving mechanism to compensate for sealing, improve the butterfly valve sealing performance, prolong the service life of the butterfly valve. Eccentric ball valve is composed of multi-layer stainless steel pieces of soft t both sides, with metal sealing and soft sealing the dual advantages. Both low temperature and high temperature, with zero leakage sealing performance. Half of an eccentric valve test pool is flow state ( Flow direction of medium and butterfly plate rotating in the same direction) , the sealing surface pressure by the drive torque and medium pressure effect on the valve plate. When the pressure is medium, oblique cone valve plate and valve seat sealing surface squeezed more tightly, the better half of an eccentric valve sealing effect. Half of an eccentric valve is mainly used for cutting, distribution, and change the flow direction of the medium inside the pipeline. Need to rotate 90 degrees, rotational torque is small, the seal can be realized. Ball valve is suitable for used as a switch and globe valve. However, in the development of nearly, ball valves are designed for throttling and flow control. Flanged gate valve, flanged butterfly valve and oxygen pressure reducing valve valve belong to the same type. , shut down part of the ball valve is a sphere, spheres revolve around the body line, to open and close the valve. Half of an eccentric valve is mainly used for cutting, distribution, and change the flow direction of the medium inside the pipeline. Ball valve is widely used in recent years a new type of valve.
