Abstract

PURPOSE: To devise to construct the whole body compact and to make the maintenance work simply without taking off the valve main body from fluid pipe lines in a diaphragm type control valve to control the valve opening by a control signal from the outside.
CONSTITUTION: This control valve 1 is provided for example in the supply pipe of town gas and the like and controlled in the valve opening by the control output from a pilot valve 3 for stabilizing the fluid pressure in the downstream-side pipe 2b. It is composed of a valve main body 4 provided with an inlet 4a and an outlet 4b mutually independent, a side lid 5 equipped to the valve main body 4 to be freely taken off and provided with a connecting line 5a between the above-said inlet 4a and outlet 4b, a diaphragm film 21 to introduce the pilot pressure of control signal into the side of a chamber 21a and to receive the outlet side pressure in another side, a valve body 8 connected to this film 21 through a prop 14 to be attached and separated on a valve seat 19, and a spring 16 to give force to close the valve 18.
