Problems solved by technology
In the unloaded running state, a small amount of air is fed into the air intake adjustment hole to ensure the oil circulation pressure required by the system when the air compressor is unloaded. The cooperation of the diaphragm and the air intake adjustment hole is used to adjust the intake air volume. Under the working environment of high-pressure oil and gas, after multiple intake impacts, it is easy to deform and cannot be reset, and cannot effectively adjust the intake air volume. Frequent maintenance and replacement of the diaphragm are required.
2. The structure of the relief valve is relatively complicated, and the valve body of the relief valve needs to process multiple air passages, which is difficult to process and the processing cost is high

The invention discloses an air intake control valve assembly of an air compressor. The air intake control valve assembly comprises an air intake valve, a releasing valve and an electromagnetic valve, wherein the air intake valve comprises an air intake valve body, a top cap assembly and a cylinder assembly; the top cap assembly comprises a cap body, a pallet and a combined cap; an air intake adjusting hole is formed in the cap body; the lower end of the air intake adjusting hole is expanded so as to form a containing cavity; a rubber ball, a compressed spring and a spring seat are arranged in the containing cavity from top to bottom; the cylinder assembly comprises a cylinder body, a guide plate, a piston, an ejector rod, a first spring and a second spring; the releasing valve comprises a releasing valve body and a piston assembly; an air inlet hole, a flow diversion hole, an exhaust hole, a control input hole and a control output hole are formed in the releasing body. According to the air intake control valve assembly of the air compressor, the rubber ball and the air intake adjusting hole are matched to adjust the air intake of the top cap assembly, the sealing performance is good; the service life is prolonged; the releasing valve is simple in structure and stable and reliable in operation.
Description
technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor intake control valve assembly. Background technique [0002] The intake valve assembly of the screw air compressor is composed of an intake valve, a discharge valve and a solenoid valve. The solenoid valve controls the action of the intake valve to realize the start, loading, unloading and shutdown of the intake valve assembly. Function. See Patent Publication No. CN202326110U for a combined intake valve for an air compressor and Patent Publication No. CN202326136U for a combined intake valve for automatically controlling an air compressor. [0003] The existing air compressor intake control valve assembly has the following problems: 1. The top cover assembly inside the intake valve adopts a diaphragm structure, see the cooperation between the air compressor intake valve and the top cover disclosed in the patent announcement number CN203516013U structu...
