This valve consists of a sealing device, a planar pairing component and a pressure regulating device. The sealing device is made of elastic material. The structure can make the sealing face reduced as little as possible. It is very favourable for processing planar pairing component and it can be make with an engine lathe. It improves on the finishing grinding which has been adopted for several decades. The valve is characterized by ease of processing, simple structrue, resistance to pressure 50 Kg/Cm2, rotary moment is one-fifth to one-twentieth of the planar sealing valve, long life (up to 100,000 times), low cost. |
