Abstract
PURPOSE: To attain safety use of gas, by disposing an electromagnetic valve for opening and closing a gas supply passage at a suitable place, for instance, on the outside of the house, so that gas may not be supplied to the gas supply line inside the house when gas is not used.
CONSTITUTION: On the upstream side of gas supplying passage 1, preferably, at a suitable place on the outside of the house, there is disposed an electromagnetic valve 4 for opening and closing the gas supplying passage 1. In using a gas appliance 2, manual switches S2, S3 are at first closed, whereupon a relay coil 12 is energized and current is supplied to the electromagnetic valve 4 via a relay switch S4, so that the gas supplying passage 1 can be opened. When an appliance cock 3 is opened after the electromagnetic valve 4 is opened, the gas appliance 2 can be used in the same way as in the conventional arrangements. In this state, if the cock switch S1 is opened, the gas supplying passage 1 can be kept open since the relay coil 12 continues to be energized via a by-pass circuit C3 and a manual switch S3.
