PRESSURE CONTROL APPARATUS FOR OPENING AND CLOSING VALVE IN DESCALER

摘要

PURPOSE: A pressure regulating device for a descaler valve is provided to prevent excessively fast opening and closing of a working fluid path by reducing the speed of a plunger that determines whether to supply working fluid. CONSTITUTION: A pressure regulating device for a descaler valve comprises a main body(10) including first and second holes(12,14) allowing the flow of working fluid, a plunger(20) which is movably installed in the main body and opens/closes a flow path between the first and second holes, and a gap regulating unit(30) which regulates the gap between the flow path and the plunger. The gap regulating unit includes a ring member(32) installed in the first hole. The ring member is formed with threads(34) on the peripheral surface thereof to be coupled to the first hole and an operating groove(36) on the exterior wall thereof in which a jig is inserted to rotate the ring member.
