Adjustable air inlet valve for air compressor

Abstract

The invention relates to the technical field of air compressors, in particular to an adjustable air inlet valve for an air compressor. The adjustable air inlet valve comprises a valve body, wherein an annular groove is formed in the inner wall of the top end of the valve body, a glass cylinder is fixedly connected to the interior of the annular groove, a driving mechanism used for providing power is arranged below the glass cylinder, a dust attraction mechanism which is matched with the driving mechanism and used for attracting dust in air is arranged outside the glass cylinder, and a cylinder body is further arranged inside the valve body. According to the adjustable air inlet valve for the air compressor, the dust in the air entering the valve body is attracted through static electricity, and the contraction degree of a conductive spring is driven to be increased after the air flow is increased, so that the sealing degree of a sealing plug to the valve body is further reduced, positive feedback is formed, the air inlet amount of the valve body reaches the maximum, internal parts of the valve body can be lubricated, and lubricating oil is supplemented after a sliding rod is restored so that the interior of the valve body can be lubricated after each time of work of the valve body so as to reduce mechanical friction of the internal parts of the valve body.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an adjustable air compressor intake valve. Background technique [0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are of reciprocating piston type, with rotating blades or rotating screws. The air compressor inlet valve is a valve structure used to control the air intake state of the air compressor. When the compressor host sucks air, due to the pressure difference, The valve plate of the intake valve of the air compressor opens quickly, and the outside air enters the air tank of the air compressor. [0003] The existing patent (notification number: CN208203509U) is a first-stage air intake valve, including a valve seat and a valve cover. The valve seat is fixedly connected to the valve cover through bolts. A first annular groove is opened at the bottom of the first flow through...

AI Technical Summary

Problems solved by technology

[0004] During the implementation of this invention, the installation position of the spring is fixed, and the contact pressure of the spring on the valve plate cannot be adjusted as required. If the pressure of the spring on the valve plate is too large, it will easily cause difficulty in inhaling. If the pressure is too small, it will easily lead to instability of the valve plate and sloshing, which will lead to poor stability of the intake air and affect the working efficiency of the gas compressor
