Abstract
PURPOSE: To prevent a generation of noise in the operation of a diaphragm type feed water valve, by providing a small-diametered projection in the main valve body, forming ribs around the projection so that they are moved along the inner wall surface of valve seat, and thereby eliminating lateral movement or shaking of the diaphragm valve body when it is moved.
CONSTITUTION: When a valve is closed with its diaphragm valve body 2 being held in contact with a valve seat 1d, water introduced from an inlet port 1a is passed through an extracting hole 3b and a small hole 4d into a pressure chamber 20, so that a valve body 2 is urged onto a valve seat 1d. On the other hand, when an actuating rod 11 is moved upward against the force of a spring 12 through the excitation of coil 8, a through-hole 4c formed in a main valve body 4 is opened and resultantly pressure in the chamber 20 becomes lower than that on the side of the inlet port 1a, so that the valve body 2 is moved upward. Here, a plurality of ribs 19 are formed around a small-diametered projection formed on the lower surface of the main valve body 4 in the manner that they are extended radially along the projection. By fitting these ribs 19 in the inner wall surface of an outlet port 1b, it is enabled to eliminate lateral movement or shaking or tha valve body 2 when it is moved.
