The invention relates to a wagon parking brake control device and a brake system. The braking system comprises a parking brake cylinder, an air source and a wagon parking brake control device, a firstair inlet of an air charging valve chamber of the control device communicates with the air source, and a fifth air inlet of an air exhaust valve chamber of the control device communicates with a parking brake cylinder. Air charging and air exhausting of the parking brake cylinder can be automatically controlled by means of the air source of the wagon air brake system, air exhausting is completedby a parking control valve without manual participation, compressed air in a one-way valve chamber flows in a one-way mode, the compressed air in the parking brake cylinder can be effectively prevented from flowing back to the air source, it is guaranteed that when a vehicle is normally used, a parking automatic brake device does not participate so as to guarantee normal operation of the air brakesystem, in addition, the starting pressure of the parking brake cylinder is controlled, it can be guaranteed that when the vehicle normally runs, compressed air of the parking brake cannot be exhausted to the atmosphere, safe running of the vehicle is guaranteed, and good practical value is achieved.
本发明涉及一种铁路货车驻车制动控制装置以及制动系统。该制动系统包括驻车制动缸、风源以及铁路货车驻车制动控制装置,控制装置的充风阀室的第一进气口和风源连通,控制装置的排风阀室的第五进气口和驻车制动缸相连通。本发明可借助铁路货车空气制动系统的风源,自动控制驻车制动缸的充风和排风,其排风由驻车控制阀完成,无需人工参与,且单向阀室内的压缩空气流动为单向流动,可有效杜绝驻车制动缸内的压缩空气逆流到风源,保证车辆在正常运用时,驻车自动制动装置不参与,以保证空气制动系统正常操纵,另外,控制驻车制动缸开启压力,可保证车辆在正常运行时,驻车制动器的压缩空气无法排向大气,保证车辆安全运行,具有很好的实用价值。
