Abstract

PURPOSE: To prevent occurrence of such an accident as gas poisoning or gas explosion, etc., by enabling a spherical valve to automatically shut off a valve seat only when a gas flow exceeds a prescribed flow rate.
CONSTITUTION: When a shutter 2 is in a blocked position, a spherical valve 26 is located on the bottom in a tapered pipe 22. When a knob of a gas cock is set to open, position and gas starts flowing from a pipe-side passage 30 in the direction of a hole 20 led to the shutter 2, in the noraml condition, the spherical valve 26 sits still as depicted in the sketch and would not sotp the gas flow. However, if the load side is released without any resistance at all, pressure differences are generated at the front and exit of an open-and-close valve seat 21 and also at the front and exit of the spherical valve 26, and therefore, when a gas flow rate becomes excessively high, the spherical valve 26 is sealed by the open-and-close valve seat 21 to shut off the gas passage.
