Abstract
PURPOSE: To visually detect gas leak by fitting a transparent cylinder which contains the magnetic float valve member which is floated by the gas hydraulic pressure between the body with the gas flow-in passage and the joint part with the gas flow-out passage.
CONSTITUTION: When the gas instrument is not in use, the float valve member 4 in the transparent cylinder 2 is attracted and maintained on the lower valve seat part 6 by the permanent magnet. Then, when the gas instrument is used, by thrusting the valve member 4 away from the valve seat part 6 by pushing up the ejector rod 11, gas from the flow-in passage A flows toward the tapered inside space S and flow-out passage B, and the valve member 4 is floated and supported by hydraulic pressure. When the hose comes off the joint part 3 during the use of the gas instrument by the earthquake, etc., the float valve member 4 is further pushed up in the tapered port 2b by increased hydraulic pressure until it contacts the upper valve seat part 5 of the permanent magnet to be attracted and held by the magnetic force to shut off the flow passage.
