The invention provides a control pipeline module for parking braking of a rail engineering vehicle, which comprises a gas circuit board, the gas circuit board is provided with a third gas circuit and a ninth gas circuit, and the gas circuit board is provided with a normally-open cock A, a pressure regulating valve, a normally-closed cock, a normally-open cock B, a pressure stabilizing air cylinder, a pressure relay, a two-position three-way electromagnetic valve, a normally-open cock C and a normally-open cock D; a third interface of the two-position three-way electromagnetic valve is communicated with external atmosphere; the normally-open cock D is provided with an exhaust hole, and the exhaust hole is connected with the air outlet end of the normally-open cock D in an openable and closable mode. According to the gas circuit board, all components are integrated on the gas circuit board, so that the mounting space is saved, and maintenance and replacement of accessories are facilitated; a normally closed door is connected in parallel in a gas circuit, so that the normal parking relieving function can be ensured when the electromagnetic valve breaks down, and the normal parking function cannot be influenced; and all controllable parts adopt plate-type structures, so that the use of pipe joints is reduced, and the risk of pipeline leakage is reduced.

    本发明提出一种用于轨道工程车停放制动的控制管路模块,包括气路板,所述的气路板具有第三气路和第九气路,在气路板上设有常通塞门A、调压阀、常闭塞门、常通塞门B、稳压风缸、压力继电器、二位三通电磁阀、常通塞门C和常通塞门D;所述的二位三通电磁阀的第三接口连通外部大气;所述的常通塞门D设有排气孔,所述排气孔可启闭的连接常通塞门D的出气端。本发明中,所有零组件集成在气路板上,节省了安装空间,且方便维护及配件的更换;在气路中并联了一个常闭塞门,可在电磁阀故障时,保证停放缓解功能正常,且不会影响正常停放功能;所有可控部件采用板式结构,减少了管接头的使用,降低了管路泄漏的风险。
