Vehicle-mounted air inlet valve

Abstract

The invention discloses a vehicle-mounted air inlet valve. The vehicle-mounted air inlet valve comprises an upper valve body and a lower valve body. The upper valve body is fixedly connected with thelower valve body. A valve cavity is cooperatively formed in the upper valve body and the lower valve body, an air inlet communicating with the valve cavity is formed in the upper valve body, an exhaust port communicating with the valve cavity is formed in the lower valve body, a valve element and a valve element spring are arranged in the valve cavity, one end of the valve element spring abuts against the lower valve body, and the other end of the valve element spring abuts against the valve element. The valve element abuts against the upper valve body under the effect of the valve element spring in order to block the portion between the air inlet and the valve cavity, multiple shunting blocks are arranged at the position, located on an air outlet, of the lower valve body, one ends of themultiple shunting blocks are evenly distributed along the circumference of the inner wall of the lower valve body, the other ends of the multiple shunting blocks are connected with the position of thecircle center of the inner wall of the lower valve body, and the shunting blocks and the lower valve body are of an integrally-formed structure. The upper valve body and the lower valve body are arranged, the effect of lowering noise can be achieved, and the shunting blocks and the lower valve body are of the integrally-formed structure, so that it is guaranteed that the shunting blocks are not separated from the lower valve body.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a vehicle intake valve. Background technique [0002] The intake valve is the core component of the air volume adjustment of the piston air compressor, and it is especially critical in the accessories of the piston air compressor. Its quality directly affects the overall performance of the screw compressor. The intake valve is widely used in daily life. It mainly controls or adjusts the capacity of the screw machine, and automatically controls the intake flow when starting, loading and unloading. At present, when the intake valve is in intake, the gas rotates through the intake port of the valve body and enters. In the valve cavity, it will cause a lot of noise when rotating the intake air. In addition, when the gas is discharged from the valve cavity from the exhaust port, it will also generate a lot of noise. Therefore, the existing air intake valve will install a diverter bloc...

Problems solved by technology

The intake valve is widely used in daily life. It mainly controls or adjusts the capacity of the screw machine, and automatically controls the intake flow when starting, loading and unloading. At present, when the intake valve is in intake, the gas rotates through the intake port of the valve body and enters. In the valve cavity, when rotating the intake air, it will cause a lot of noise

In addition, when the gas is discharged from the valve cavity from the exhaust port, it will also generate a lot of noise. Therefore, the existing air intake valve will install a diverter block at the gas outlet, and the diverter block is fixed at the gas outlet by a circlip. However, in the Under the action of long-term high-pressure gas, the diverter block is easy to fall off from the gas outlet, which affects the noise reduction effect
