Abstract

184,940. Keith & Blackman Co., Ltd., J., Keith, G., and Pointon, J. E. June 20,1921. Safety cut-off valves for gas supply systems in which the valve is opened manually and maintained open by the gas pressure acting on a diaphragm. The manual actuating-means is arranged so as to be. operative to move the valve from its seat but inoperative in the reverse direction. The diaphragm A clamped between two parts of the casing is pressed against a valve seat B surrounding the inlet port by a helical spring D adjusted by a split screwed ring H and bearing against a member G guided in the casing and having a head bearing against the diaphragm. The manually actuated spindle E has a head F adapted to engage the member G to open the valve.
