Description

Technical Field

[0001] The utility model relates to the technical field of height valves, in particular to an integral height valve installation structure with integrated air supply function. Background Art

[0002] Existing bogies with bolsters often use the bolster as an additional air chamber for the air spring. A level valve is mounted on the bolster, and a pipeline connects the level valve to the additional air chamber interface on the bolster. Because the level valve mounting base and the additional air chamber interface are independently welded to the bolster, the inherent limitations of the welding process make it difficult to accurately position the level valve mounting base and the additional air chamber interface, often leading to difficulties in connecting the piping between the level valve and the additional air chamber. This is especially true when the level valve mounting base and the additional air chamber interface are close together, as the connecting pipeline is short and has limited adjustment space, making installation quality even more difficult.

[0003] At the same time, the height valve mounting seat and the additional air chamber interface are welded and processed together with the bolster. On the one hand, sufficient processing allowance needs to be reserved, and on the other hand, it will also cause cumbersome procedures and low production efficiency.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop an integrated height valve installation structure with integrated air supply function. Utility Model Content
