Abstract

PURPOSE: To enable the manual opening and closing and the disassembling and assembling to be performed without relation to the action of a compressing spring by the integration of a spindle for opening and closing the diaphragm by a piston, a holding plate, the compressing spring, and a spring tightening body into one body and enclosing the unit in a valve tube body.
CONSTITUTION: The spindle 7 which openes and closes the diaphragm 2 is constituted as one assembly 35 by the piston 9, the comprissing spring 11, the spring holding plate 15, and the spring tighening nut 13. The assembly is enclosed in the valve tube body 12 by imparting an initial load to the compressing spring 11 by the nut 13. In this constitution, since the assembly 35 can be mounted and removed in an intact state in assemblying and disassembling the valve, the free elongation of the compressing spring is not yielded, and the disassembly and assembly can be facilitated.
