Abstract

The invention discloses a medium pressure air inlet valve, which includes an air inlet valve seat, a sealed gasket, a valve element, a spring, and a fulcrum bearing. The air inlet valve seat is provided with an air inlet cavity body, and the two ends of the air inlet cavity body communicates with the surface of the air inlet valve seat; the top surface of the sealed gasket contacts with the innerwall of the air inlet cavity body in a separable mode; the valve element is a T-shaped revolution body, and includes an element head and a leading rod vertically fixed to the lower part of the elementhead; a first groove used for containing the sealed gasket is formed in the top surface of the element head, and the sealed gasket is nested in the first groove; the spring sleeves the outer side ofthe leading rod, and the upper end of the spring abuts against the bottom surface of the element head; and a limiting hole is formed in the top surface of the fulcrum bearing, the leading rod is slidably arranged in the limiting hole, the lower end of the spring abuts against the top surface of the fulcrum bearing, and a flow passage is formed in the fulcrum bearing and / or between the fulcrum bearing and the inner wall of the air inlet cavity body. Compared with the prior art, the sealed gasket in the medium pressure air inlet valve is not prone to deforming and falling off, and integrated leakproofness is improved.

Description

technical field [0001] The invention relates to the technical field of intake valves, in particular to a medium-pressure intake valve. Background technique [0002] Scroll air compressors are widely used in industrial, agricultural, transportation and other industries where compressed air is needed due to their high efficiency, low noise, small size, and benefits for energy saving and environmental protection. The main moving part of the scroll air compressor is the scroll, which is only meshed and does not produce wear, so the service life is longer than that of the piston and screw compressors. It is an ideal power source for pneumatic machinery. In the scroll air compressor, the scroll of the main moving parts is divided into a moving scroll and a fixed scroll, and the moving scroll and the fixed scroll are equipped with scroll plates. The rotary disks are combined with each other to form a compression chamber. When the movable scroll is driven by the crankshaft to move ...
