Title: Biplane valve
Inventor: YASUFUKU SAKITO
IPC: F16K1/36
Filed: 2000-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a biplane valve openable/closable smoothly by small rotation moment and unnecessitating drain in the upstream side flow passage when a valve element packing is replaced. SOLUTION: Because a gap is generated between a valve element and a valve seat, even if the valve element is rotated and a valve body is closed, friction is not generated due to sliding of the valve element on the valve seat and the valve element can be smoothly opened/closed by the small rotation moment. When pressure fluid is supplied to the inside of a sealing means 34 by a pressure fluid supplying means, the sealing means 34 is deformed to the valve element side and is closely adhered and seals the gap between the valve element and the valve body. When fluid within the downstream side flow passage is made to flow down, fluid pressure within the upstream side flow passage becomes higher than that on the downstream side and thereby a flexible part 27 of the valve element is bent to the downstream side and is seated on a valve seat 23 and the valve body is completely sealed.  Because the valve element packing 29 can be replaced in a state that the sealing means 34 is operated, drain of the upstream side flow passage becomes unnecessary.
