Problems solved by technology

However, since the quick-release valve is sealed by a sheet-shaped bidirectional piston in the housing, a slight offset of the piston will cause a loose seal.
This directly affects the braking effect of the automobile braking system during use, and makes the quick release valve prone to failure, shortening its service life
[0004] In addition, after the elasticity of the spring fails, it will also affect the normal use of the quick release valve, and the reliability is not high
At the same time, the compressed air is directly discharged during the deflation process, so the noise is very loud

Embodiment Construction

[0021] As shown in the figure, the quick release valve of the brake air chamber of the automobile is installed in the braking system of the automobile, and it is composed of a valve body 1, a valve seat 2, a valve plate 3, a muffler 4 and a connecting bolt 7, etc.

[0022] The valve body 1 is a three-way pipe fitting with a cavity inside. Two of the nozzles of the valve body 1 are an air inlet 11 and an air outlet 12 respectively, and the cavity connects the air inlet 11 and the air outlet 12 . The end of the other nozzle is provided with an inner ring groove 13, and the inner ring groove 13 is recessed in the inner surface of the valve body 1. The valve seat 2 is installed in the cavity of the valve body 1, and the end of the valve seat 2 is blocked by the jumper 6 installed in the inner ring groove 13, so that the valve seat 2 is fixed in the valve body 1. In this embodiment, a sealing gasket 8 for sealing is installed between the valve seat 2 and the inner surface of the v...

Abstract

A fast air-releasing valve for the braking air chamber of car is composed of a valve body with air inlet hole and air outlet hole, a valve seat with a central air releasing hole communicated with said air inlet and outlet holes, and a movable valve flap between the inner holes of air inlet and outlet holes, which can move to seal one of them.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a quick-release valve for an automobile brake air chamber. Background technique [0002] In the braking system of a car, the brake valve generates compressed air during braking. The compressed air enters a three-way joint through the brake pipeline, and the three-way joint enters the axle through the left and right brake pipelines respectively. Push the brake shoes in the left and right air chambers to brake the vehicle. When the brake is released, the compressed air in the left and right brake air chambers must pass through the left and right brake pipelines and return to the three-way joint, and then return to the brake valve from the brake pipelines to be discharged. Since the air pressure in the left and right brake chambers and the air pressure in the brake pipeline cannot be discharged in time, it takes about 2 seconds to release the entire brake. In this ...
