弁。A cone-shaped diaphragm made of a flexible material is arranged in a polymerized state inside the cone-shaped integral body, and the top of the cone-shaped diaphragm is inserted into the inner cavity of the cone-shaped integral body. In the diaphragm type check valve fixed to the bottom, the cone-shaped diaphragm is provided with an annular seat portion projecting in the outer circumferential direction in the shape of a brim at the edge of the opening, and the cone-shaped diaphragm , the cone-shaped diaphragm has a cone-shaped diaphragm which is arranged so as to be superimposed on the inside of the integral body so that the outer circumferential surface excluding the seat portion is suspended in the inner cavity of the integral body by contacting the inner surface of the open opening portion of the integral body; ,
A diaphragm-type check valve characterized in that a plurality of folds along the axial direction of the diaphragm are integrally formed and arranged radially from the top of the diaphragm toward the opening side.
