The invention provides a control valve with a relieving function, comprising: a main valve, the main valve is provided with a control upper cavity and a control lower cavity which are not communicated with each other, the control upper cavity is communicated with a train pipe, and the control lower cavity is communicated with an auxiliary air cylinder; the inflation valve comprises a main valve body, a driving valve element and an inflation valve element, the main valve body is provided with a driving cavity and an inflation cavity, the driving cavity is divided into a first driving cavity and a second driving cavity by the driving valve element, the first driving cavity is communicated with the emergency chamber, the second driving cavity is communicated with the train pipe, and the inflation valve element is movably arranged at an air outlet of the inflation cavity; an air inlet of the inflation cavity is communicated with the acceleration relief air cylinder; the driving valve element is provided with an inflation position and a closing position, when the driving valve element is located at the inflation position, the driving valve element drives the inflation valve element to open the air outlet of the inflation cavity, and when the driving valve element is located at the closing position, the inflation valve element blocks the air outlet of the inflation cavity. By means of the scheme, the problem that a control valve cannot meet the use requirement can be solved.

    本发明提供了一种具有缓解功能的控制阀,包括:主阀,主阀具有互不连通的控制上腔和控制下腔,控制上腔与列车管连通,控制下腔与副风缸连通;充气阀,包括阀体主体、驱动阀芯以及充气阀芯,阀体主体具有驱动腔和充气腔,驱动阀芯将驱动腔分隔为第一驱动腔和第二驱动腔,第一驱动腔与紧急室相连通,第二驱动腔与列车管相连通,充气阀芯可移动地设置于充气腔的出气口处,充气腔的进气口与加速缓解风缸相连通;其中,驱动阀芯具有充气位置和关闭位置,在驱动阀芯位于充气位置时,驱动阀芯驱动充气阀芯打开充气腔的出气口,在驱动阀芯位于关闭位置时,充气阀芯封堵充气腔的出气口。通过本方案,能够解决控制阀无法满足使用需求的问题。
