Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in detail.

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

[0018] Such as figure 1 As shown, a reconnection valve with automatic switching function, the reconnection valve is composed of reconnection valve part 1 and shutoff valve part 2, the main function is to ensure that the braking and relief functions of all reconnection locomotives are coordinated , it only needs to operate the brake of the lead locomotive to ensure that the braking relief of the double-connected locomotive is consistent with that of the lead locomotive, and after the locomotive is...

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, in particular to a reconnection valve with automatic conversion function. Background technique [0002] With the continuous increase of railway transportation volume, it is necessary to use double-row locomotives or multiple locomotives for reconnection traction. When multiple trains of locomotives are reconnected for traction by using reconnection valves, the crew can ensure The braking and relief functions of the heavy-duty locomotive are coordinated with those of the lead locomotive. During reconnection operation, once the locomotive is separated, the reconnection valve will automatically maintain the pressure of the brake cylinder to protect after separation. [0003] In order to realize the switching between the main locomotive and the double locomotive, the existing double valve has a manual switching valve. When the locomotive is used as the main locomotive, the switching button ...
