The invention discloses a fluid valve, a heat management system and a vehicle, and the fluid valve comprises a valve shell, a plurality of flow channel openings and a through hole; the valve element comprises a connecting shaft and a body, the connecting shaft is connected with the body to drive the body to rotate synchronously, and the connecting shaft penetrates through the penetrating hole. The connecting shaft is sleeved with the sealing piece, the outer circumferential wall of the sealing piece makes contact with the valve shell, the inner circumferential wall of the sealing piece is provided with a main sealing lip and a first sealing lip, in the axial direction of the connecting shaft, the main sealing lip is located on the side, facing the body, of the first sealing lip, and the protruding length of the main sealing lip is larger than that of the first sealing lip. The main sealing lip and the first sealing lip make contact with the connecting shaft and deform. According to the fluid valve, when the main sealing lip fails in sealing, due to the action of fluid pressure, the sealing function of the main sealing lip is replaced by the first sealing lip, and the dynamic sealing reliability of a sealing piece can be improved.
本发明公开了一种流体阀、热管理系统和车辆,所述流体阀包括:阀壳,阀壳设有多个流道口,阀壳设有穿过孔;阀芯包括连接轴和本体,连接轴与本体相连以带动本体同步转动,连接轴穿设于穿过孔;密封件外套于连接轴,密封件的外周壁与阀壳接触,密封件的内周壁设有主密封唇口和第一密封唇口,在连接轴的轴向方向上,主密封唇口位于第一密封唇口的朝向本体的一侧,主密封唇口的凸出长度大于第一密封唇口的凸出长度,主密封唇口和第一密封唇口分别与连接轴接触且发生变形。本发明的流体阀,能够在主密封唇口出现密封失效时,由于流体压力作用、通过第一密封唇口替代主密封唇口的密封功能,利于提高密封件的动态密封可靠性。
