Abstract

PURPOSE: To present an accurate and sure inspecting method to examine the quality of a gas-cock with an overflow-prevention valve.
CONSTITUTION: For inspecting a gas-cock Y with an overflow-prevention valve constructed by equipping a valve seat part 5 in one body with a cylinder 4 containing a ball valve 3 to be vsertically moved inside a gas passage 2 connecting between a gas-inlet and outlet of a gas-cock main body 1, a governer Z1, a valve V1, and a laminar flow meter A are provided between the gas-cock Y and a pressure gas source. When a pressure control valve N is gradually opened and a set point is obtained, the discharge at the stage is detected by the laminar flow meter A to be indicated by a digital panel meter O, while the quality is examined by a digital setter P. Then, when the flow is intercepted by the overflow-prevention valve, the instantaneous maximum discharge at the stage is similarly indicated by a digital panel meter F, while the quality is examined by a digital setter G.
