The invention discloses an empty and load vehicle pressure adjusting valve and a working method, solves the problem that in the prior art, a pressure adjusting valve pipeline is complex in arrangement, and has the beneficial effects that the pipeline is simplified, and the failure rate is reduced, and according to the specific scheme, the empty and load vehicle pressure adjusting valve comprises a first shell and a second shell; a middle body is arranged between the first shell and the second shell, a first pressure adjusting assembly is arranged in the second shell, a first cavity is formed in the pressure adjusting assembly, a second cavity is formed in the upper side of the first pressure adjusting assembly, a third cavity is formed between the second shell and the middle body, and a second pressure adjusting assembly is arranged between the middle body and the first shell. The lower side of the second cavity is communicated with the control valve, the upper side of the second cavity is communicated with a fourth cavity of the pressure adjusting valve, the bottom side of the first shell is communicated with a fifth cavity of the pressure adjusting valve, the upper side of the second cavity is further communicated with a sixth cavity, and the sixth cavity is communicated with the brake cylinder. The first pressure regulating assembly can move towards the second cavity to cut off a passage between the second cavity and the brake cylinder.

    本发明公开了一种空重车压力调整阀及工作方法,解决了现有技术中压力调整阀管路设置复杂的问题,具有简化管路、降低故障率的有益效果,具体方案如下:一种空重车压力调整阀,包括第一壳体和第二壳体,第一壳体与第二壳体之间设置中间体,第二壳体内设置第一调压组件,调压组件内设置第一腔体,第一调压组件的上侧设置第二腔体,第二壳体与中间体之间设置第三腔体,中间体与第一壳体之间设置第二调压组件,第二腔体的下侧与控制阀连通,第二腔体的上侧与压力调整阀的第四腔体连通,第一壳体的底侧与压力调整阀的第五腔体连通,第二腔体的上侧还与第六腔体连通,第六腔体与制动缸连通,第一调压组件能够朝向第二腔体移动以切断第二腔体与制动缸的通路。
