Abstract
PURPOSE: To improve reliability by preventing gas leakage when gas is not used, by closing a shut-off valve in the gas disuse state and then by opening the shut-off valve only when the gas is used.
CONSTITUTION: When the keying signal of an apparatus stopcock shows closed state, shut-off valve 3 is opened and when an irrespirable signal arrives, electric current supply to shut-off valve 3 is stopped approximatery 3W10sec later with a signal from the shut-off valve keying circuit to close shut-off valve 3, preventing leakage of gas. As apparatus stopcocks 9 are all closed after gas is used, shut-off valve 3 is closed and residual gas pressure in the piping at the downstream side of the shut-off valve 3 is monitored by the residual gas pressure detecting circuit to detect the gas leakage.
