The invention discloses a multi-way valve, a heat management system and a vehicle, and belongs to the technical field of control valves, the multi-way valve comprises a shell, a valve element and a driver, the valve element is rotatably mounted in a mounting cavity of the shell, a sealing piece is arranged between the inner circumferential wall of the mounting cavity and the valve element, and the driver drives the valve element to rotate through a rotating shaft; different circulation channels can be switched so as to control fluid; a plurality of convex ribs are arranged on the side face, facing the through hole, of the sealing piece and correspondingly surround the conduction opening, the convex ribs abut against the inner circumferential wall of the installation cavity, the convex ribs can abut against the inner circumferential wall of the installation cavity more stably when being pressed and deformed, the counter-acting force of the sealing piece after being pressed can be increased, and the sealing piece can be prevented from being damaged. The pressure deformation resistance of the sealing piece is improved, an effective sealing effect is achieved between each through hole and the corresponding communicating opening, the situation that sealing failure of a single flow channel influences the sealing performance of other flow channels is avoided, and the whole multi-way valve is more reliable.
本发明公开了一种多通阀、热管理系统及车辆,属于控制阀技术领域,多通阀包括壳体、阀芯和驱动器,阀芯转动安装于壳体的安装腔内,并在安装腔的内周壁与阀芯之间设置密封件,利用驱动器通过转轴驱动阀芯转动,能够切换不同的流通通道以实现对流体的控制;密封件朝向通孔的一侧面设有多条凸筋,多条凸筋分别对应环绕导通口设置,通过多条凸筋分别与安装腔的内周壁相抵接,在凸筋受压发生形变时能够更稳定地抵压于安装腔的内周壁,能够增大密封件受压后的反作用力,提高密封件的抗压变能力,在每个通孔与对应的导通口之间处起到有效的密封作用,避免单个流道的密封失效对其它流道的密封性产生影响,使多通阀整体更加可靠。
