In a valve consisting of a valve body 1, a valve cover 2, a valve body 3, a valve stem 4, etc., the cylindrical portion 8 is erected on the valve cover 2 so as to surround the valve stem 4. A piston 10 is movably disposed inside the cylindrical portion 8, and sealed spaces 15.
16, and the valve body 1 is connected to the upper and lower sealed spaces 15, 16 from the front and rear of the valve body 3 via the first control valves 32, 33.
A valve body opening/closing device that can selectively supply the fluid inside. 2 Utility model registration claim 1 consisting of upper and lower sealed spaces 15 and 16 of the piston 10 inside the cylindrical portion 8 of the valve cover 2 being interconnected by a pump 30 via a second control valve 31 Valve body opening/closing device as described in . 3 The first control valve 32.33 is a set of three-way solenoid valves, whose a end and C end are communicated with the sealed spaces 16.15 at the lower and upper parts of the piston 10, respectively, and whose b end is connected to the valve box. Utility model registration claim No. 1 which communicates with each other before and after the valve body 3 of No. 1. The valve body opening/closing device according to item 1 or 2. 4. The valve body opening/closing device according to claim 2, wherein the second control valve 31 is a three-way solenoid valve, and the pump 30 is a pump with a reversible discharge direction.
