Problems solved by technology

Such technology is useful for reducing the exhaust noise of the quick-release valve, but it can only reduce the airflow noise generated when the exhaust port is exhausted when the brake is released, and cannot reduce the high-frequency vibration of the diaphragm 4 during braking. Howling
Moreover, after the shock absorbing equipment is installed, there are still problems such as taking up a lot of space and high cost.

Abstract

The invention relates to a built-in membrane of a quick release valve for pneumatic braking and the quick release valve. The built-in membrane comprises a membrane body, and a first boss structure is arranged on the upper surface of the membrane body; the center of the first boss structure coincides with the center of the membrane body; a second boss structure is arranged on the lower surface of the membrane body, and the center of the second boss structure coincides with the center of the membrane body; on the lower surface of the membrane body, at least two grooves extending in the radius direction from the center of the membrane body are arranged from the circumcircle of the second boss structure to the edge of the membrane body; the grooves are symmetrical about the center of the membrane body; the center line of each groove is a curve.

Description

technical field [0001] The invention belongs to the field of automobile braking, and specifically refers to a built-in diaphragm and a quick-release valve used for a quick-release valve in a pneumatic brake vehicle. 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 is as follows: figure 1 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 comp...
