Abstract

The invention belongs to the technical field of automobile part processing, and puts forward a check valve with a sound attenuation function. The check valve comprises a check valve component, a firstconnector element and a sound attenuation component, wherein one end of the check valve component is used for communicating with compressed air; one end of the first connector element is connected with an air suspension system; the sound attenuation component comprises a barrel, a bottom plate and a cover body, wherein the barrel, the check valve component and the first connector element mutuallycommunicate to form a three-way structure; the bottom plate is arranged on the bottom of the barrel; the cover body covers the outer side of the barrel and is connected with the bottom plate; the cover body is hollow; the outer wall of the barrel is provided with a first air hole, and the bottom plate is provided with a second air hole; the barrel is full of sound attenuation materials; and the inner cavity of the barrel, the first air hole, the inner cavity of the cover body and the second air hole form a sound attenuation channel. Through the above technical scheme, the problem in the priorart that noise is big when the air suspension system discharges air can be solved.

Description

technical field [0001] The invention belongs to the technical field of auto parts processing, and relates to a one-way valve with a sound-absorbing function. Background technique [0002] Air suspension system has become the choice of more and more high-end models in recent years. By reducing or raising the ground clearance of the chassis, the car not only has the comfort of a car, but also takes into account the passing performance of an off-road vehicle. According to the different road conditions and the signal of the distance sensor, the car trip computer will judge the height change of the vehicle body, and then control the air compressor and the exhaust valve, so that the spring will be automatically compressed or extended, and the height of the chassis will be adjusted. However, when the air suspension system is exhausted, a large amount of gas needs to be discharged in a short period of time, which will generate disturbing noise and reduce the ride comfort.
