Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings.

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0018] like figure 1 As shown in the figure, a reconnection valve with automatic switching function, the reconnection valve is composed of a reconnection valve part 1 and a shut-off valve part 2, and its main function is to ensure that the braking and mitigation functions of all reconnection vehicles are coordinated. , it is only necessary to operate the main locomotive brake to ensure that the braking relief of the reconnected locomotive is consistent with that of the main locomo...

Abstract

The invention discloses a double-heading valve with an automatic changeover function. The double-heading valve is composed of a double-heading valve portion and a shutoff valve portion. The double-heading valve portion comprises a double-heading piston and a double-heading check valve which are arranged in a double-heading valve body. The shutoff valve portion comprises a shutoff piston and a shutoff check valve which are arranged in the double-heading valve body. Pathways which communicate with a brake cylinder pipe, an average pipe, a purpose pipe, a main blast pipe and a double-heading signal pipe are mounted on the double-heading valve body. According to the double-heading valve with the automatic changeover function, status signal pathways are added on the double-heading valve body and a manual changeover valve is removed. When a locomotive is used as a double-heading locomotive, a double-heading signal is inputted and the double-heading valve is in a double-heading position, it is guaranteed that the release of brake of the double-heading locomotive is consistent with that of a leading locomotive and the coordination control over the double-heading locomotive and the leading locomotive is realized, and therefore misadjustment, leaking of adjustment and the like caused by manual rotation of the changeover valve are avoided. The double-heading valve with the automatic changeover function reduces workloads, guarantees traffic safety, improves transport efficiency and has higher social benefits and higher economic benefits.

Description

technical field [0001] The invention belongs to the technical field of railway vehicles, and particularly relates to a reconnection valve with automatic switching function. Background technique [0002] With the continuous growth of railway traffic, it is necessary to use double locomotives or multiple locomotives for reconnection traction. The use of reconnection valves can make multiple locomotives reconnected for traction. The crew only needs to operate the main locomotive brakes to ensure that The braking and mitigating effects of the reconnected locomotive are in harmony with those of the main service locomotive. In the reconnection operation, once the locomotive is separated, the reconnection valve will automatically maintain the pressure of the brake cylinder to play a protective role after separation. [0003] In order to realize the switching between the main service locomotive and the reconnecting locomotive, the existing reconnecting valve has a manual switching ...
