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

[0019] As shown in the figure, the quick release valve of the brake air chamber of this automobile is installed in the brake system of the automobile. It is composed of valve body 1, valve seat 2, valve plate 3, muffler 4 and connecting bolt 7.

[0020] The valve body 1 is a three-way pipe 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. An inner ring groove 13 is opened at the end of the other nozzle, and the inner ring groove 13 is recessed on the inner surface of the valve body 1. The valve seat 2 is installed in the cavity of the valve body 1, and the circlip 6 installed in the inner ring groove 13 blocks the end of the valve seat 2 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 valve body 1.

[0021] The valve seat 2 is cyl...

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 particularly relates to a quick release valve used in a brake air chamber of an automobile. 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 connector through the brake pipeline, and the three-way connector enters the axle through the left and right brake pipelines. In the left and right air chambers, the brake shoes are pushed to brake the driving. When the brake is released, the compressed air in the left and right brake air chambers must pass through the left and right brake pipes to return to the three-way connector, and then return to the brake valve from the brake pipe to be discharged out. Because 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. This ...
