The invention provides a remote release control device of a railway vehicle brake cylinder. The remote release control device comprises a pneumatic control valve body (4) and three two-position three-way electromagnetic valves installed on the upper surface of the pneumatic control valve body. The three electromagnetic valves are respectively a remote release electromagnetic valve (1), an impulselimiting electromagnetic valve (2) and a communication electromagnetic valve (3). Four piston type valve elements are arranged in the pneumatic control valve body and include a cut-off valve element,an impulse limiting valve element, a communication valve element and a remote release valve element. A brake gas inlet, a brake gas outlet, a first release gas inlet, a second release gas inlet and arelease gas outlet are formed in the lower surface of the pneumatic control valve body. According to the remote release control device, the remote release function, the impulse limiting function and the braking force distribution adjusting function are integrated through the simple structural design, the reliability of the brake control device can be improved, a user can maintain and overhaul thebrake control device conveniently, and therefore the maintenance cost is reduced.
Description
technical field [0001] The invention relates to the field of rail vehicle brake control, in particular to a remote mitigation control device for a rail vehicle brake cylinder. Background technique [0002] As a large-capacity public transportation tool, the safety of rail vehicles is directly related to the safety of passengers. As an important technical equipment to ensure train safety, the braking system plays a pivotal role in the rail transit system. [0003] As a key component in the rail vehicle braking system, the brake control device mainly includes an electrical control part and a pneumatic control part. The electrical control part receives various command information such as braking and mitigation to ensure the realization of braking and mitigation functions. In the current brake control device, there are a large number of air circuit actuators and complex structures, which not only reduces the reliability of the brake control device, but also increases the mainten...
