層との間に補強布を介在するものである請求項１
記載の液体用ダイヤフラム弁。[Scope of Claim for Utility Model Registration] (1) A flexible diaphragm forming the valve body is located at a position facing the valve seat in the valve case at the peripheral edge so as to isolate the front side and the back side that come into contact with liquid. In a liquid diaphragm valve that is fixedly arranged and opens and closes by moving the front side of the diaphragm into and out of contact with the valve seat by driving the operating shaft back and forth in the axial direction, the diaphragm is connected to the center part of the back side of the diaphragm valve. A conductive rubber layer is provided between the rubber film substrate and the synthetic resin film on the surface side, and the conductive rubber layer is insulated from the valve case, and the conductive rubber layer and the valve case are insulated. A diaphragm valve for liquid, characterized in that it is equipped with an electrical continuity detection device. (2) Claim 1, wherein the diaphragm has a reinforcing cloth interposed between the rubber membrane base material and the conductive rubber layer.
Diaphragm valve for liquids as described.
