Through in-depth analysis of the anti-surge conditions of the raw gas compressor,an anti-blocking and anti-surge valve was developed for the characteristics of the blockage of the flow channel of the compressor and supporting equipment caused by the easy adhesion and deposition of the raw gas.This paper expounds the selection idea and structural design of the valve,and puts forward that the valve body adopts the angular structure of small inlet and large outlet to reduce the flow dead zone in the valve and reduce the flow rate of the valve outlet.The internals of the valve are designed with the double anti-jamming structure of the scraper and the anti-jamming ring.At the same time,the selec-tion of pneumatic actuators and the configuration of control accessories are introduced.The valve has successfully passed the field application,which provides a solution with certain reference value for the anti-surge valve of raw gas compressor.
