The invention provides a trigger structure of a brake valve, and belongs to the technical field of vehicle braking. The problem that the detection precision of an existing brake valve trigger structure is inconvenient to correct is solved. According to the trigger structure of the brake valve, the brake valve comprises a valve body, a main valve element is arranged in the valve body, an ejector rod capable of driving the main valve element to move is arranged on the valve body in a sliding and penetrating mode, the trigger structure comprises a linear sensor, a pressing plate fixedly connected to the end of the valve body and a protective cover arranged outside the ejector rod in a sleeving mode, the protective cover is fixedly connected to the upper surface of the pressing plate, and a detection cavity is formed between the protective cover and the pressing plate; the linear sensor is provided with a telescopic detection head and a columnar connector, a supporting sleeve is arranged on the pressing plate in a penetrating mode, the supporting sleeve is located outside the valve body and located on the pressing plate in the sliding direction of the ejector rod, the connector is arranged in the supporting sleeve in a penetrating mode from the bottom of the supporting sleeve, and a locating piece enabling the connector to be located in the supporting sleeve is arranged on the supporting sleeve. The ejector rod is fixedly connected with a guide seat located in the detection cavity, and the detection head abuts against the bottom of the guide seat. The brake valve triggering structure is convenient in precision correction.

    本发明提供了一种制动阀的触发结构,属于车辆制动技术领域。它解决了现有制动阀触发结构检测精度校正不便的问题。本制动阀的触发结构,制动阀包括阀体,阀体内设有主阀芯,阀体上滑动穿设有能带动主阀芯移动的顶杆,触发结构包括线性传感器、固连于阀体端部的压板和套设于顶杆外的护罩,护罩固连于压板的上表面且两者之间形成检测腔,线性传感器具有能伸缩的检测头和呈柱状的连接头,压板上穿设有支撑套,支撑套位于阀体外并沿顶杆的滑动方向定位在压板上,连接头由支撑套的底部穿设于支撑套内,支撑套上设有使连接头定位于支撑套内的定位件,顶杆上固连有位于检测腔内的导向座,检测头与导向座的底部抵靠。本制动阀触发结构精度校正方便。
