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.
本发明提供了一种轨道车辆制动缸的远程缓解控制装置,包括气控阀体(4)和安装在气控阀体的上表面的三个二位三通式电磁阀。三个电磁阀分别为远程缓解电磁阀(1)、冲动限制电磁阀(2)和连通电磁阀(3)。气控阀体的内部设置有四个活塞式阀芯,四个阀芯分别为截断阀芯、冲动限制阀芯、连通阀芯和远程缓解阀芯。气控阀体的下表面开设有制动气进口、制动气出口、第一缓解气进口、第二缓解气进口和缓解气出口。本发明提供的远程缓解控制装置以简单的结构设计集成了远程缓解、冲动限制及制动力分配调节功能,不仅有利于提高制动控制装置的可靠性,还便于用户进行维护和检修,从而降低维护成本。
