In the gas meter from the cutoff stroke quantitative inspection jig null gas entrance

摘要

PROBLEM TO BE SOLVED: To simply and accurately judge the propriety of a cut-off stroke value of a cut-off valve without operation of the cut-off valve in a state where a gas meter is kept linked to gas piping. ;SOLUTION: This inspection jig is provided with a cylindrical jig body 60 which is mounted on the external surface of a meter casing 10 to house a base end side of a return shaft 32 and a press shaft 65 to be housed into the jig body 60 free to slide. The press shaft 65 slides together with the return shaft 32 until it is retained on a valve body 22 (intermediate shaft 42) at a retreating position by a pressing operation of the press shaft 65. A cut-off stroke value of the valve body 22 is inspected based on the pressing value of the press shaft 65.;COPYRIGHT: (C)1998,JPO
