Abstract

PURPOSE:To proud a single valve with both function of a sealing type opening valve and a remote opening and closing valve by disposing a sealing plate which prevents leak from a primary chamber and a secondary chamber except in emergency operation and having the sealing plate function as a usual opening and closing valve after the plate is pierced. CONSTITUTION:During the usual operation, a primary chamber A and a secondary chamber B are kept closed with a sealing plate 35. When pressure is sent from an operation hole 29 communicated with a space C under a piston 19, said piston 19 acts together with a rod 22 stuck thereto. By the action of said piston 19, a disk 32 at the end thereof causes the sealing plate 35 pierced to communicate the primary chamber A and the secondary chamber B with each other. When the pressure in a working pressure chamber 18 is returned to the original value, the end part of a movable valve 39 comes into contact with the annular ring 38 of a partition wall 12, whereby closing both the primary chamber A and the secondary chamber B.
