The invention discloses a steering brake valve and a telescopic boom forklift, and belongs to the technical field of steering control and brake control. The steering brake valve comprises a high-pressure oil inlet, a priority valve, a pressure reducing valve and an electromagnetic reversing valve; oil entering from the high-pressure oil inlet enters the priority valve and the pressure reducing valve; the priority valve is connected with the steering gear feedback oil way, the steering gear and the working oil cylinder, and the circulation direction of oil is controlled through feedback of the steering gear feedback oil way. One path of an outlet of the pressure reducing valve is connected with a brake, the other path is connected with a parking braking oil path through an electromagnetic reversing valve, and releasing and starting of parking braking of the vehicle are controlled through the electromagnetic reversing valve; the priority valve, the pressure reducing valve and the electromagnetic directional valve are integrated into one steering brake valve, the functions of steering priority, traveling oil supply, parking release and the like are integrated, the system is simplified, and the problems of large space proportion, complex pipeline connection and the like are solved.
本发明公开了一种转向制动阀及伸缩臂叉车,属于转向控制和制动控制技术领域,包括高压进油口、优先阀、减压阀和电磁换向阀;从高压进油口进入的油液进入优先阀和减压阀;优先阀分别连接转向器反馈油路、转向器、工作油缸,通过转向器反馈油路的反馈控制油液的流通方向;减压阀的出口一路连接制动器,另一路通过电磁换向阀连接驻车制动油路,通过电磁换向阀控制车辆驻车制动的解除和开启;本发明将优先阀、减压阀、电磁换向阀集成位一个转向制动阀,集转向优先、行车供油、驻车解除等功能于一体,简化系统,解决了空间占比大和管路连接复杂等问题。
