The embodiment of the invention provides a valve element, a control valve, a heat management system and a vehicle, the valve element comprises a valve rod, the valve rod comprises a main body part and an adjusting part which are arranged in the axial direction, and the adjusting part is used for at least partially stretching into a valve port so that the control valve can have a closed state and a throttling state; the adjusting part comprises a guide face and a throttling face, in the throttling state, the guide face abuts against the inner wall of the valve seat, and the throttling face and the inner wall of the valve seat define a fluid channel for fluid to pass through. Due to the fact that the guide face abuts against the inner wall of the valve seat, the inner wall of the valve seat can support the valve rod of the valve element, the valve rod is prevented from being scoured by fluid at a high speed to generate high-frequency shaking, the overall stability of the valve element in the throttling state is improved, and the stable flow adjusting function of the control valve is guaranteed. And the service lives of the valve core and the control valve are prolonged.
本申请实施例提供了一种阀芯、控制阀、热管理系统及车辆,阀芯包括阀杆,阀杆包括沿轴向设置的主体部和调节部,调节部用于至少部分伸入阀口,以使得控制阀具有关闭状态和节流状态;其中,调节部包括导向面和节流面,在节流状态下,导向面抵接于阀座的内壁,节流面与阀座的内壁围合形成用于流体通过的流体通道。由于导向面与阀座的内壁相抵接,阀座的内壁可以为阀芯的阀杆提供支撑作用,避免阀杆受到来自流体的高速冲刷而产生高频抖动,提高了阀芯在节流状态下整体的稳定性,保证控制阀稳定的流量调节功能,延长了阀芯及控制阀的使用寿命。
