The invention discloses a manual empty and load adjusting device provided with a pressure limiting valve, which comprises the pressure limiting valve, an empty and load change-over cock, a pressure reduction air cylinder and a brake pipeline, wherein the empty and load change-over cock is provided with an empty position, a load position and an exhaust hole; an upstream pressure input port of the pressure limiting valve is connected with an air brake of a vehicle, and a downstream pressure output port is connected with a brake cylinder; a branch is arranged on a connecting passage of the downstream pressure output port and the brake cylinder, the brake cylinder is connected with a pressure reduction air cylinder through the branch, and the empty and load change-over cock is connected to thepassage between the brake cylinder and the pressure reduction air cylinder in series; another branch is arranged at the end, which is away from the brake cylinder, of the empty and load change-over cock on the connecting passage of the brake cylinder and the pressure reduction air cylinder, and the pressure reduction air cylinder, the brake cylinder and an empty pressure signal access port in thepressure limiting valve are connected; and an empty and load position pressure display is arranged on a valve cover of the pressure limiting valve. By the adoption of the device, the pressure of thebrake cylinder when the vehicle is empty or loaded can be adjusted, especially the pressure value of the brake cylinder at the empty position can be accurately controlled, and brake over-sticking is reduced.

    一种配装限压阀的手动空重车调整装置,其包括限压阀、空重车转换塞门、降压风缸以及制动管路;空重车转换塞门设有空车位、重车位两个位置及排气孔;限压阀的上游压力输入口与车辆的空气制动机连接、下游压力输出口与制动缸连接;下游压力输出口与制动缸的连接通路上设有1个分支,该分支将制动缸与降压风缸连接,空重车转换塞门串联在二者之间的通路上;在制动缸与降压风缸的连接通路上,空重车转换塞门远离制动缸的一端设有另一分支,将降压风缸、制动缸与限压阀上的空车压力信号接入口连接;限压阀的阀盖上设置空重位压力显示器。采用本装置可实现车辆空车与重车制动缸压力的调整,尤其能精确控制空车位制动缸压力值,减少制动超粘现象。
