A brake valve structure without a hydraulic source of a brake system comprises a shell, a screw plug assembly, a piston and a piston rod, the shell is arranged in the vertical direction, the upper end of the shell is open, the screw plug assembly is installed at the opening of the upper end of the shell, the piston is arranged in the shell and divides an inner cavity of the shell into an oil storage cavity and an oil output cavity, and the piston is connected with the piston rod. The piston rod extends downwards to be fixedly connected with a first spring seat, a spring is connected between the first spring seat and the inner bottom of the shell, the upper end of the piston rod extends out of the shell, the piston rod is provided with a sealing face, the sealing face is located above the piston and provided with a gap, the piston rod is provided with an oil hole, and the two ends of the oil hole are communicated with the oil storage cavity and the oil output cavity respectively. The shell is provided with two connectors, and the two connectors are communicated with the oil storage cavity and the oil liquid output cavity respectively. When the brake valve works, the dual sealing effect is achieved, the problem of damage caused by using a sealing leather cup is avoided, the using reliability and safety of the brake valve are improved, and the cost is directly reduced.

    一种刹车系统无液压源的刹车阀结构,包括壳体、螺塞组件、活塞和活塞杆,壳体上下方向设置且上端开口,螺塞组件安装在壳体上端开口处,活塞设置在壳体内并将壳体内腔分隔成储油腔和油液输出腔,活塞上连接有活塞杆,活塞杆向下延伸固定连接有第一弹簧座,第一弹簧座与壳体内底部之间连接有弹簧,活塞杆上端延伸至壳体外,活塞杆上设置有一密封面,密封面位于活塞上方且具有间隙,活塞杆上设置有油孔,油孔两端分别与储油腔和油液输出腔连通,壳体上设置有两个接口,两个接口分别与储油腔和油液输出腔连通。本发明的刹车阀工作时达到双重的密封效果,避免使用密封皮碗出现的损坏问题,提高了刹车阀使用的可靠性和安全性,直接地降低了成本。
