ルダイアフラム付突出形受圧部。 A disc member having a circular convex part in the center, a gasket seating surface formed around the circular convex part, a pressure guiding hole having one end opened in the convex part surface and the other end opened in the side surface of the disc, and this disc member. A cylindrical member is fitted externally to the convex portion of the member, and the other end of a capillary is attached with the free end of the cylindrical member opened and one end is connected to a pressure guiding hole opened on the surface of the convex portion. A seal diaphragm is attached to the periphery of the back-up plate, which is sandwiched between the periphery of the back-up plate and held by a ring to maintain a gap between the fitted back-up plate and the outer surface of the back-up plate, and the outer surface of the back-up plate. In the protruding pressure receiving part with a seal diaphragm, the disc member and the cylindrical member are made of a steel material such as carbon steel or stainless steel, and a corrosion-resistant annular substrate is embedded around the convex part of the disc member. At the same time, the gasket seating surface is covered with an annular thin plate made of corrosion-resistant material, and the inner peripheral edge of this annular thin plate is liquid-tightly welded to the annular base plate. When the member is fitted, a rod-shaped member made of corrosion-resistant material is embedded in the outer surface of the cylinder in the axial direction of the cylinder across the annular members at both ends, and a thin plate made of corrosion-resistant material is further wrapped around the outer surface of the cylindrical member. The four circumferential edges of the cylindrical member are welded liquid-tightly to the annular member and rod-shaped member at both ends. A protruding pressure receiving part with a seal diaphragm characterized by being liquid-tightly welded to an annular member.
