The invention relates to the technical field of braking, and provides a relay valve and a braking system. The first piston is arranged in the shell and divides an inner cavity of the shell into a control cavity and a brake cavity, the shell on the side of the control cavity is provided with a sinking table part, and the sinking table part extends into a piston cavity of the first piston; the second piston is arranged in the sinking table part and divides an inner cavity of the sinking table part into a sub-control cavity and a drainage cavity, the sub-control cavity is communicated with the control cavity, a first channel is arranged among the drainage cavity, the control cavity and the piston cavity, and a third channel is arranged between the piston cavity and an exhaust port of the brake cavity. According to the relay valve, automatic drainage can be achieved, and in the working process of the relay valve, water in the control cavity is automatically drained out of the valve through the first channel and the third channel along with movement and resetting of the first piston and the second piston.
本发明涉及制动技术领域,提供继动阀和制动系统。继动阀包括:设置在壳体中并将壳体的内腔分隔为控制腔和制动腔的第一活塞,控制腔侧的壳体具有沉台部,沉台部伸入第一活塞的活塞腔中;内置于沉台部并将沉台部的内腔分隔为子控制腔和排水腔的第二活塞,子控制腔与控制腔连通,排水腔与控制腔及活塞腔之间设置有第一通道,活塞腔与制动腔的排气口之间设置有第三通道。本发明的继动阀能够实现自动排水,在继动阀的工作过程中,控制腔中的水随着第一活塞和第二活塞的运动和复位,通过第一通道和第三通道自动排出阀外。
