Engine pressure release valve exhaust noise elimination device

Abstract

The invention provides an engine pressure release valve exhaust noise elimination device. The engine pressure release valve exhaust noise elimination device comprises an air inlet cavity and an air outlet cavity; the air inlet cavity is provided with an air inlet channel, the air outlet cavity is provided with an air outlet channel, a connecting channel is arranged between the air inlet cavity and the air outlet cavity, and a flow disturbing device is arranged in the air inlet cavity. According to the engine pressure release valve exhaust noise elimination device, a flow disturbing resonance effect on air flow can be achieved through the flow disturbing device, energy of the air flow can be reduced, and first-time noise reduction is achieved; irregular motion of the air flow is reduced in the process that the air flow penetrates through micro holes formed in the middle cylinder wall to enter the air flow exhaust cavity, and second-time noise reduction is achieved; after the energy and the mobility of the air flow in the air flow exhaust cavity of a noise elimination cylinder are controlled, noise generated by the air flow exhausted through the micro holes is reduced again, and third-time noise reduction of the noise elimination device is achieved; the air flow flows away along with an air exhaust pipeline, the purpose of pressure release valve exhaust noise elimination is achieved, and the device is installed in the air exhaust pipeline and does not occupy external space.

Description

technical field [0001] The invention relates to an exhaust muffler device for an engine pressure relief valve. Background technique [0002] At present, pressure relief valves have been widely used in automobile engines. With the development of technology and the improvement of living standards, people pay more and more attention to the pursuit of driving. The most important thing is that the comfort of the driving process has become an increasingly important topic, and noise control during driving is an important indicator of car comfort. The original pressure relief valve is accompanied by the noise of airflow during the working process, which is a potential problem for those who pursue comfortable and quiet driving. dissatisfied. In order to solve the problem of noise reduction in the exhaust of the pressure relief valve, a muffler with the publication number CN204127464U reduces the occurrence of noise by buffering the air pressure.
