Abstract

The invention relates to a quick release valve used for braking and a shell of the same. The shell comprises an upper shell body and a lower shell body. The upper shell body is tightly connected with the lower shell body through a bolt and comprises a main upper shell body and an air inlet formed in the upper end of the main upper shell body, and an air outlet is formed in each of two sides of the main upper shell body. The lower shell body comprises a main lower shell body and an exhaust valve, a boss structure recessing on the lower surface of the exhaust value and projecting on the upper surface of the exhaust valve is arranged on the exhaust valve, exhaust ports are formed in the top end of the boss structure, and central lines of the exhaust ports, a central line of the air inlet and a central line of the boss structure are coincided. According to the technical scheme, by improving a structure of an exhaust valve and improving the positions of the air outlet and the exhaust valve, impact on a membrane from a high-pressure airflow can be alleviated, the situation that the membrane impacted by the high-pressure airflow vibrates in high frequency is restrained, and squeaking during exhausting is alleviated.

Description

technical field [0001] The invention belongs to the technical field of brake systems, in particular to a brake quick-release valve housing and a quick-release valve. Background technique [0002] The quick release valve is used in truck pneumatic brake models, and it is generally arranged in the brake pipeline close to the brake chamber, which plays the role of quick exhaust when the brake is released, so as to quickly release the brake. [0003] The structure of the quick release valve in the prior art is as follows: Figure 1 to Figure 3 As shown, when assembling, stick the deflation valve 5 on the lower casing 2, place the sealing ring 3 in the pre-opened sealing groove of the upper casing 1, place the diaphragm 4 on the deflation valve 5 and use it four times. The bolt and the spring washer 6 pass through the bolt 7 and tightened. The above-mentioned assembly requires the centers of the two parts to be aligned. [0004] When the car brakes, the compressed air from the b...
