Description

Technical Field

[0001] The invention belongs to the technical field of brake valve cleaning tanks, and in particular relates to a rail transit vehicle brake valve cleaning tank device. Background Art

[0002] At present, the rail transit vehicle production and maintenance industry generally uses a special cleaning machine to clean the inner cavity passage of the brake valve. However, due to the large number of air circulation passages in the brake valve cavity, which are complex and irregular in shape, and even have blind holes, oil-containing pollutants are formed during use due to the influence of compressed air, wear and external environment. At the same time, after the grinding process is completed within the prescribed maintenance period, the powder shed by the oilstone and the copper chips ground down fall into the inner cavity and air path, and are more difficult to clean after mixing with the residual oil inside. Therefore, it is difficult to completely remove the impurities such as oil stains and grease formed during the production and use of the brake valve, which can easily block the brake air passage, causing brake and relief failure, and bring serious hidden dangers to the safety of rail transit vehicle operation. In the existing cleaning method, only high-pressure water and compressed air are used to spray and clean the outer surface and key parts of the brake valve, and the inner cavity passage of the brake valve cannot be effectively cleaned.
