PRESSURE REDUCING VALVE FOR CONTROLLING STEADY FLOW

摘要

Disclosed is a pressure reducing valve for rectification control. The pressure reducing valve for rectification control of the present invention is capable of simultaneously mitigating the water hammer or hunting at an entrance side and an exit side, thereby stabilizing a pressure reducing function from the water hammer and hunting. The pressure reducing valve has a known double-chamber pressure reducing structure in which a housing is horizontally provided; a water inlet pipe is horizontally formed at an entrance side of the housing; a water outlet pipe is horizontally formed at an exit side of the housing; and a disc, a stem, and a piston are provided inside the housing along water flowing from the entrance side to the exit side. The pressure reducing valve comprises: an entrance-side water hammer offset plate which is vertically erected through a fixing unit inside the water inlet pipe and has multiple water inlet hole horizontally formed therein; and an exit-side water hammer offset plate which is vertically erected through a fixing unit inside the water outlet pipe and has multiple water outlet holes horizontally formed therein, wherein the water outlet holes have a smaller diameter than the water inlet holes.
