Abstract

967,651. Valves. CRANE CO. July 27, 1962, No. 28954/62. Heading F2V. In a gate valve in which the gate 19, 21 is movable in a chamber 5, 6, 10 transversely of the flow passage 13, 14 and co-operates with opposed seats to open and close the valve, accidental overpressure in the valve chamber in closed position, such as may arise from temperature changes, is automatically prevented by a double-seating valve member 32, 33 housed in a chamber in the gate and movable between opposed seats, the gate chamber being in communication through these seats with the upstream and downstream sides of the valve in closed position and being in communication, through a passage in the gate, with the valve chamber 5, 6, 10. As shown, the gate is in separate halves spring-urged apart and located together by a ring 47, the passage between the respective valve and gate chambers being provided by the clearance between these parts.
