Abstract

PURPOSE: To rationalize the use of the safety valve by a method wherein an expansion chamber is provided within the valve and an expanded part of water at the time of additional burning is accommodated in the expansion chamber.
CONSTITUTION: In case the pressure of water rises up as a result of expansion of water in a water pipe due to additional burning, a valve body 12 slides from its closed position A to a B position along the inner peripheral surface of the portion of the valve 11 surrounding a clearance 17 so that the clearance 17 expands to thereby accommodate the expanded part of the water. In other words, the clearance 17 expands prior to the opening of the valve body 12 so as to form the expansion chamber of a predetermined maximum capacity capable of accommodating the expanded part of the water in the water pipe. On the other hand, during the normal operation as the safety valve, the valve body 12 moves such that an O-ring 13 of the valve passes beyond the position B so that the seal between the valve body 12 and the inner peripheral surface of the valve 11 is hardly maintained and the water in the water pipe flows outside from an outlet 11B through the valve 11.
