APPARATUS FOR DETECTING MINUTE LEAK OF LP GAS

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for detecting a minute leak of LP gas which eliminates mutual connections by pipings thereby to reduce a count of parts and working costs and, reduces the number of connecting points thereby to lower the possibility of the leak. ;SOLUTION: A regulator 13 having an entrance directly connected to an exit of a regulator 111 which reduces a pressure of a high pressure gas from ports 11a/, 11a₂ further reduces the pressure of the supplied gas and outputs to a main conduit 6. A valve-shutting pressure of a regulator 14 having an entrance directly connected to the exit of the regulator 111 is set higher than that of the regulator 13. A minute leak detection part 12 detects a flow of gas flowing through the regulator 14, and judges a minute leak based on a flow rate pules generated from a flow rate pulse generation part 12a. A single housing wherein the regulators 111, 13 and 14 are formed is set to the detection part 12, and exits of the regulators 14, 13 are directly connected to a gas entrance part 12c and a gas exit part 12d.;COPYRIGHT: (C)1997,JPO
