The invention provides an improved air inlet valve structure. The improved air inlet valve structure comprises an air inlet valve body, a driving air source control valve and an emptying valve, wherein the air inlet valve body comprises an air inlet cover and an air inlet valve element; a cavity with an opening is formed in the air inlet cover; the air inlet valve element is arranged in the cavity movably and can move to open or close the cavity; the driving air source control valve is arranged on the air inlet cover and communicates with the cavity; and the emptying valve is arranged between the driving air source control valve and the air inlet cover and communicates with the cavity. Owing to the driving air source control valve, the opening degree of the air inlet valve element can be controlled by a channel of air source only; accordingly, when the improved air inlet valve structure is used on an air line system of a compressor, the air displacement of the compressor can be adjusted by 100%-0%, the air utilization range of the compressor is greatly increased, and application of a pressure reducing valve can be reduced further; and meanwhile, because the improved air inlet valve structure is provided with the emptying valve, a pressure relief function of the improved air inlet valve structure is fulfilled, and the overall reliability of the improved air inlet valve structure is greatly improved.
Description
technical field [0001] The invention relates to the technical field of intake valves, in particular to an improved intake valve structure. Background technique [0002] The current air intake valve mainly drives the piston to move back and forth through the driving air source, and then drives the valve core to open or close the air inlet of the valve cover. However, when the driving air source is input, it will be input to the left and right sides of the piston at the same time. As a result, the movement of the piston is blocked, which greatly affects the opening and closing of the valve core. Accordingly, if the intake valve is applied to the air circuit system of the compressor, it can only adjust 100%-40% of the discharge volume of the compressor, greatly affecting the discharge effect of the compressor. [0003] Therefore, it is necessary to provide a technical means to solve the above defects. Contents of the invention [0004] The purpose of the present invention i...
