The invention relates to an empty and load vehicle valve and a brake pressure adjusting method.The empty and load vehicle valve comprises a valve body assembly, a piston assembly and a valve element assembly, a longitudinal inner cavity is formed in the valve body assembly, and the piston assembly comprises a first flexible part, a second flexible part, a piston and a shaft sleeve; the valve element assembly comprises a valve element body and a first elastic piece. A pressure pre-control cavity is formed between the first flexible part and the second flexible part, a pressure output cavity and a pressure input cavity are further formed in the valve body assembly, and the valve element body is pushed by the piston to move downwards so that the pressure output cavity and the pressure input cavity can be communicated to balance the preset pressure in the pressure pre-control cavity. The internal structure of the empty and load vehicle valve is simplified, the structure is more concise, and the output air pressure is accurately adjusted by matching with the input air pressure electronically adjusted by the electromagnetic valve.

    本申请涉及一种空重车阀及制动压力调节方法,包括:阀体组件、活塞组件以及阀芯组件,阀体组件内设有纵向的内腔,其中,活塞组件包括:第一柔性件、第二柔性件、活塞以及轴套;阀芯组件包括:阀芯本体与第一弹性件;第一柔性件与第二柔性件间设有一压力预控腔室,阀体组件内还设有压力输出腔室与压力输入腔室,通过活塞推动阀芯本体下移使压力输出腔室与压力输入腔室连通平衡压力预控腔室内的预设压力。本申请简化了空重车阀的内部结构,使结构更加简洁,配合电磁阀电子调节后的输入气压做到精准调节输出气压。
