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 air pressure braking of an automobile and the quick-release valve. The built-in membrane comprises a membrane body. The upper surface of the membrane body is provided with a boss structure. The center of the boss structure coincides with the center of the membrane body. The lower surface of the membrane body is provided with at least two grooves which extend from the center of the membrane body in the radius direction. The grooves are symmetrical about the center of the membrane body. The center line of each groove is a curve. Since the two surfaces of the built-in membrane of the quick-release valve are arranged to be of the boss structure and the groove structure respectively, high-frequency vibration generated when the membrane is impacted by high-pressure air is suppressed.

Description

technical field [0001] The invention belongs to the field of automobile braking, and specifically relates to a built-in diaphragm of a quick release valve and a quick release valve used in a pneumatic brake vehicle type. Background technique [0002] The quick release valve is used in truck air brake models. It is generally arranged in the brake pipeline near the brake air chamber, and 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 in the figure, when assembling, the air release valve 5 is glued to the lower casing 2, the sealing ring 3 is placed in the pre-opened sealing groove of the upper casing 1, and the diaphragm 4 is placed on the air release valve 5 and then used four Tighten the bolt and the spring washer 6 through the bolt 7. The above assembly requires the center of the two parts to be aligned. [0004] When the car brakes, the compr...
