Compressor air inlet control valve with flow guide function

Abstract

The invention discloses a compressor air inlet control valve with a flow guide function, belongs to the technical field of air inlet control valves, and aims to solve the problems that an air inlet valve is easily abraded after a long time since an internal structure of the air inlet control valve is repeatedly impacted by an existing air inlet control valve which presses a piston baffle through an air cylinder, and the service life of the air inlet control valve is prolonged. An air outlet groove in the lower end of the air inlet control valve is directly exposed, so that dust is easily mixed into the air outlet groove, and the cleanliness in the air inlet control valve is influenced; the circular motion diameter of the extrusion push block is matched with the distance between the piston baffle and the attaching groove, then reciprocating circular motion replaces one-way linear motion, the acting force of the piston baffle on the air inlet control valve can be greatly reduced, internal mechanisms are prevented from being abraded, and the service life of the air inlet control valve is prolonged; along with downward movement of the funnel flow guide cover, one ends of the two traction long rods are closed, then dust can be prevented from being mixed into the air inlet control valve easily, and the cleanliness of the interior of the air inlet control valve is kept.

Description

technical field [0001] The invention relates to the technical field of air intake control valves, in particular to a compressor air intake control valve with a flow guiding function. Background technique [0002] The compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas, and is the heart of the refrigeration system. The exhaust pipe discharges high temperature and high pressure refrigerant gas to provide power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression→condensation→expansion→evaporation. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. . [0003] When the compressor is in the loading state, the piston baffle of the intake control valve moves down to the inside, and direct air intake follows the gap between the piston baffle and the air inlet, but this intake method is prone to intake resistance. The big phenomenon is that the exi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a compressor air intake control valve with diversion function, which solves the problem that in the background art, when the compressor is in a loaded state, the piston baffle of the air intake control valve moves down to the inside and follows the piston baffle. The gap between the air inlet and the air inlet is used for direct air intake, but this air intake method is prone to the phenomenon of large air intake resistance. The existing air intake control valve presses the piston baffle through the cylinder, but this top pressure method The internal structure of the intake control valve will be repeatedly impacted. If things go on like this, it will easily cause wear to the intake valve. Cleanliness inside the intake control valve
