Abstract

PURPOSE: To prevent the generation of undue stress on layers of diaphragms by pinching the diaphragm ring under the high pressure on both sides of annular portions in the periphery of plurality of metallic circular disc and by welding the periphery as one unit.
CONSTITUTION: The necessary number of metallic circular discs composed of special steel and usable as diaphragms, and the central portion of which are curved in a dome form, is piled up and the dome portion of the multilayer metallic disc 1 is pinched with a high pressure by means of templets 2a, 2b. Then the diaphragm ring 3, 3 is placed over both sides of the annular part of the periphery of the metallic disc 1a, and the both rings 3, 3 are contacted closely by applying the necessary tightening force through the pinching templets 4, 4 and the peripheries of three, the two rings 3, 3 and the metallic disc 1 pinched between rings are welded together in one unit.
