Abstract
PURPOSE: To completely prevent the leakage of gas when preventing its excessive outflow, by providing a valve element or a valve seat with elasticity and by shaping the side line of the longitudinal section of a valve hole as an arc in order to increase the area of contact of the valve with the surface of the valve hole.
CONSTITUTION: When gas flows out excessively, a ball valve 6 is fitted in the valve hole 4 of a valve seat 5 by the abnormal flow of the gas. Since the ball valve 6 is provided with elasticity, its surface is tightly fitted to the valve hole 4. Since the side line 4a of the longitudinal section of the valve hole 4 is shaped as a conve arc, the area of contact of the ball valve 6 with the valve hole 4 is increased to surely prevent any leakage of the gas.
