The invention relates to a controllable pressure regulating type empty and load truck sensing valve which comprises a sensing part, a pressure regulating part and an exhaust part which are integrated into a whole. The feeler lever of the sensing part is only responsible for detecting the change of the empty weight position and is not responsible for adjusting the pressure of the pressure reducing air cylinder, the curved side face of the ejector block converts the Z-direction displacement of the feeler lever into the X-direction displacement of the pressure adjusting part, and therefore the pressure of the brake cylinder and the pressure reducing air cylinder is adjusted through the pressure adjusting part. The empty load detection and the pressure control of the pressure reduction air cylinder are separated, the curved side face of the top block is designed according to actual requirements, a stepless adjustment mode can be designed, a step type empty load vehicle can also be designed, and the pressure of a brake cylinder can be completely controlled and adjusted. And meanwhile, the feeler lever is only responsible for detecting the change of the empty and load positions, the safety and reliability are higher, the sensing part only plays a detection role and does not integrate other functions, and the problems of dust cover falling, seasonal leakage faults and the like of an existing empty and load vehicle are solved.
本发明涉及一种可控调压式货车空重车传感阀,包括集成为一体的传感部、调压部和排风部。本发明传感部的触杆只负责探测空重位置的变化,不负责对降压风缸的压力调整,顶块的曲线型侧面将触杆的Z向位移转换为调压部的X向位移,从而通过调压部调整制动缸和降压风缸的压力。空重探测和降压风缸的压力控制分开,顶块的曲线型侧面按照实际需要进行设计,既能设计成无极调整方式,也可设计为有级式空重车,对制动缸压力实现完全可控可调。同时由于触杆只负责探测空重位置的变化,更加安全可靠,传感部只起探测作用,没有集成其它功能,不会产生现有空重车的防尘罩脱落、季节性漏泄故障等问题。
