Title:
PRESSURE GUIDE INSPECTION JIG OF VALVE DRIVING PRESSURE AND PRESSURE GUIDE INSPECTION METHOD OF VALVE DRIVING PRESSURE
Document Type and Number:
Japanese Patent JP2017116391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure guide inspection jig of a valve driving pressure and a pressure guide inspection method of the valve driving pressure which are capable of easily and reliably performing a pressure guide inspection of a pressure guide driving valve.SOLUTION: A pressure guide inspection jig 1 of a valve driving pressure is a pressure guide inspection jig screwed with pipe joints 8, 22 and inspects a pressure guide state of a driving pressure of a valve 2 in a state where a pressure guide tube 14 is joined with an end part 8a of a pipe joint, and includes: a cylindrical jig main body 16; a fitting part 18 having a first notch 18a in which an opening of one end is notched in a cylindrical height direction of the jig main body so as to allow fitting toward the pipe joint while avoiding a guide pressure tube extending from the pipe joint; and a turning part 19 formed on the other end side of the jig main body and fastening/unfastening the pipe joint so as to be threadably advanced or retracted from the valve by allowing a fitting joint to turn.SELECTED DRAWING: Figure 1
