Adjustable air compressor air inlet valve

Abstract

The invention relates to air compressor air inlet valves, in particular to an adjustable air compressor air inlet valve. The adjustable air compressor air inlet valve comprises a valve rod; the valverod is sequentially sleeved with a first valve seat, a valve plate and a second valve seat from top to bottom; a plurality of vertically-through internal threaded holes are formed in the end face, facing the valve plate, of the second valve seat; the multiple internal threaded holes are evenly distributed in the surface of the second valve seat; and an adjusting sleeve is connected into each innerthreaded hole through threads, a spring is arranged in each inner threaded hole, the upper portion of each spring extends out of the corresponding inner threaded hole, and the lower portion of each spring extends into the corresponding adjusting sleeve and makes contact with the bottom end face of the corresponding adjusting sleeve. According to the adjustable air compressor air inlet valve, thepressure of the springs on the valve plate can be flexibly adjusted according to actual use requirements, the air inlet stability is improved, and normal work of an air compressor is guaranteed.

Description

technical field [0001] The invention relates to an air compressor intake valve, in particular to an adjustable air compressor intake valve. Background technique [0002] The air compressor intake valve is a valve structure used to control the intake state of the air compressor. In the prior art, when the main unit of the compressor sucks air, due to the pressure difference, the valve plate of the intake valve of the air compressor opens rapidly, and the external air enters the air tank of the air compressor; when the main unit of the compressor stops, the air compressor The internal pressure of the machine gas tank is greater than the external pressure, and the valve plate can be tightly closed in time and quickly. There is also an unloader on the intake valve of the air compressor, and the unloader can open the valve plate to release the compressed air in the air tank of the air compressor when the main engine of the compressor is not working. [0003] In the prior art, t...

AI Technical Summary

Problems solved by technology

[0004] During the use of the primary air intake valve of the above technical solution, 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 lead to difficulty in inhaling air, and the main engine of the compressor needs to do more work to fully absorb the compressed air from the air tank of the air compressor; if the pressure of the spring on the valve plate is too small, it will be easy The valve plate is unstable and easy to shake, resulting in poor air intake stability and affecting the working efficiency of the gas compressor
