Abstract

PURPOSE: To completely eliminate outward leakage of fluid by allowing the peripheral edge of the metal diaphragm of a diaphragm valve to be sealed certainly.
CONSTITUTION: This diaphragm valve is built up by integrating each annular seat 21, 22 onto both peripheral edge surfaces of a metal diaphragm 3 through a fusing process, while the diaphragm 3 is not integrated with a rod supporting body. Therefore, the twisting force in case of fastening the rod supporting body 2 onto a valve box 1 is buffered, and generation of twist, crease, and crack of the diaphragm 3 is prevented certainly. Further, each of sealing members 24, 25 is inserted respectively between the annular seats 21/22 in the integral form with the diaphragm 3 and the shoulder surface 1a of the valve box 1 and the inner edge surface 2a of the rod supporting body 2, and double sealing structure is formed. Therefore, more perfect sealing performance can be obtained, and fluid leakage from the peripheral edge can be prevented certainly, even if the diaphragm 3 is used under severe condition.
