The hydraulic control brake valve comprises a valve body, a valve rod, a first spring, a valve sleeve and a feedback valve element, an inner cavity is formed in the valve body, the valve rod is inserted into the inner cavity and is in sliding connection with the valve body, the valve sleeve is inserted into the inner cavity and is fixed relative to the position of the valve body, and the two ends of the first spring are connected with the valve rod and the main valve element correspondingly; the main valve element is located in a valve sleeve inner cavity of the valve sleeve and connected with the valve sleeve in a sliding mode, a main valve element inner cavity is formed in the main valve element, the feedback valve element is inserted into the main valve element inner cavity, the main valve element is connected with the feedback valve element in a sliding mode, and the main valve element inner cavity is communicated with the valve sleeve inner cavity. The main valve element inner cavity is formed in the main valve element and blocked through the feedback valve element, so that hydraulic oil acts on the inner wall of the upper end of the main valve element to provide upward feedback force, the magnitude of the feedback force is directly separated from the main valve element, the diameter of the main valve element continues to be increased, the flow is increased, and the action speed of the brake is increased; the braking speed is accelerated, and the safety is improved.
本发明涉及一种液控制动阀,包括:阀体、阀杆、第一弹簧、阀套和反馈阀芯,阀体形成有内腔,阀杆插入内腔中并与阀体滑动连接,阀套插入内腔中并相对阀体位置固定,第一弹簧两端分别与阀杆和主阀芯连接,主阀芯位于阀套的阀套内腔中并与阀套滑动连接,主阀芯形成有主阀芯内腔,反馈阀芯插入主阀芯内腔中,主阀芯与反馈阀芯滑动连接,主阀芯内腔与阀套内腔相连通。本发明通过在主阀芯内设置主阀芯内腔并使用反馈阀芯封堵,使得液压油作用在主阀芯上端内壁以提供向上的反馈力,从而使反馈力大小和主阀芯直接脱离了关系,使得主阀芯直径继续增大,流量增大提高了制动器的动作速度,加快了刹车速度,提高了安全性。
