Suction pressure regulating valve and parallel compressor system

Abstract

The present disclosure provides a suction pressure regulating valve and a parallel compressor system. The suction pressure regulating valve includes a valve body having a suction channel for communicating with a suction port of a compressor; a valve core disposed in the valve body and allowed to extend into and retract from the suction channel to change a flow area of the suction channel; and a rotating member rotatably connected to the valve body and cooperating with the valve core, wherein the rotating member is configured to rotate relative to the valve body so as to drive the valve core to extend into and retract from the suction channel. In this way, by using the suction pressure regulating valve, real-time regulation may be made according to different working conditions or flows, which may allow the compressor to achieve a good pressure equalization effect under various working conditions without repeated disassembly and assembly of pipelines for debugging, and to have superior reliability and safety.
