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 driving structure disposed between the valve body and the valve core, wherein the valve core is caused to extend into the suction channel in a case that the driving structure is in a first state, and the valve core is caused to retract from the suction channel in a case that the driving structure is in a second state. In this way, by using the suction pressure regulating valve, real-time regulation may be made according to different working conditions or flows, which allows the compressor to achieve a good pressure equalization effect under various working conditions without repeated disassembly and assembly of pipelines for debugging, and have superior reliability and safety.
