INSERTION-TYPE VALVE FOR CONTROLLING A FLOW RATE, CAPABLE OF REDUCING NOISE DUE TO A HYDRAULIC CHANGE WHEN FLUID FLOWS

摘要

PURPOSE: An insertion-type valve for controlling a flow rate is provided to simplify an installation process and save installation cost since a housing is simply inserted into a pipe without change in a pipe's structure.;CONSTITUTION: An insertion-type valve for controlling a flow rate comprises a housing(110), a flow-rate control unit, an elastic member(150) and a noise reducing unit. Fluid passes through the inlet(111) and the outlet(112) of the housing. The raised part(114) of the housing is externally protruded along the outer circumferential surface and is inserted into a pipe. The flow-rate control unit moves depending on fluid pressure and controls the flow rate of the fluid. One end of the elastic member is supported on the inner stepped part(113) of the housing and the other end of the elastic member is supported on the flow-rate control unit.;COPYRIGHT KIPO 2011
