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

Embodiment Construction

[0031] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0032] This application provides an upper housing of a quick release valve for braking, such as Figure 5 and Figure 6 As shown, the upper housing body 100 is included, and an air inlet chamber 200 is arranged above the upper housing body 100. The air inlet chamber 200 communicates with the inner cavity of the upper housing body 100, and the gas enters the upper housing body through the air inlet chamber. , and apply pressure to the diaphragm 300 .

[0033] The air inlet chamber 200 includes a cylindrical cavity 201 and a conical cavity 202 positioned below the cylindrical cavity; the end with a small diameter in the conical cavity i...

Abstract

The invention relates to an upper shell of quick release valve for braking, as well as the quick release valve. The upper shell comprises an upper shell body, wherein a gas inlet cavity is formed above the upper shell body and is communicated with an inner cavity of the upper shell; the gas inlet cavity comprises a cylindrical cavity and a conical cavity positioned below the cylindrical cavity; one end, with smaller diameter, of the conical cavity is connected with the lower end of the cylindrical cavity; one end, with bigger diameter, of the conical cavity is communicated with the inner cavity of the upper shell body. According to the technical scheme, the conical cavity is formed in the gas inlet cavity of the upper shell, so the condition that a membrane generates high-frequency vibration when being subjected to high-pressure gas impact can be inhibited, gas inlet squeal can be reduced and gas inlet speed can be increased.

Description

technical field [0001] The invention belongs to the technical field of pneumatic braking, in particular to an upper casing of a quick-release valve for braking 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 4 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...
