Abstract
PURPOSE: To surely seal a valve box to a supporting cylinder and easily perform repair and replacement work for a part in the valve box, by such constitution that a bite sealing member fitted to the supporting cylinder of a diaphragm valve is held between the supporting cylinder and the valve box through the method of screwing of a fixing nut.
CONSTITUTION: In a diaphragm valve constituted by holding a diaphragm 3 between a valve box 1 and supporting cylinder 2 built with a valve push rod or the like, a fixing nut 20 fitted to the supporting cylinder 2 is screwed to an external thread 21 of the valve box 1, simultaneously a bite sealing member 22 similarly fitted to the supporting cylinder 2 is equipped between the fixing nut 20 and the supporting cylinder 2. This bite sealing member 22 is formed with a wedge face 22a at its point end, and this wedge face 22a is pressed to a tapered surface 1b formed to the valve box 1 by tightening the fixing nut 20 through a tightening collar 23 to bite between the valve box 1 and the supporting cylinder 2 and seal the valve box to the supporting cylinder.
