The invention provides a train control valve which comprises a control valve body, an air inlet of the control valve body is communicated with a train pipe, and a brake air outlet of the control valve body is communicated with a brake cylinder. The emergency valve is provided with an emergency upper cavity and an emergency lower cavity, and an air inlet of the emergency lower cavity is communicated with a train pipe; the release valve comprises a release valve body, a driving valve element and a release valve element, the release valve body is provided with a driving cavity and a release cavity, the driving cavity is divided into a first cavity and a second cavity by the driving valve element, the first cavity is communicated with the emergency upper cavity, the second cavity is communicated with the train pipe, and the release valve element is movably arranged at an air outlet of the release cavity; the relief cavity is communicated with a brake air outlet of the control valve; the driving valve element is provided with a relieving position and a blocking position, when the driving valve element is located at the relieving position, the driving valve element drives the relieving valve element to open the relieving cavity, and when the driving valve element is located at the blocking position, the relieving valve element blocks the relieving cavity. By means of the scheme, the problem that the train pipe inflation time is long can be solved.

    本发明提供了一种列车控制阀,包括:控制阀,控制阀的进气口与列车管相连通,控制阀的制动出气口与制动缸连通;紧急阀,具有紧急上腔和紧急下腔,紧急下腔的进气口与列车管相连通;缓解阀,包括缓解阀体、驱动阀芯以及缓解阀芯,缓解阀体具有驱动腔和缓解腔,驱动阀芯将驱动腔分隔为第一腔室和第二腔室,第一腔室与紧急上腔相连通,第二腔室与列车管相连通,缓解阀芯可移动地设置于缓解腔的出气口处,缓解腔与控制阀的制动出气口相连通;驱动阀芯具有缓解位置和封堵位置,在驱动阀芯位于缓解位置时,驱动阀芯驱动缓解阀芯打开缓解腔,在驱动阀芯位于封堵位置时,缓解阀芯封堵缓解腔。通过本方案,能够解决列车管充气时间长的问题。
