The invention discloses a distribution valve for a heat pump system. The distribution valve comprises a valve body and a valve element. A liquid inlet is formed in a first end of the valve body, a first liquid outlet is formed in a second end of the valve body, and a second liquid outlet is formed in the side wall of the valve body; the valve element is arranged in an inner cavity of the valve body and comprises a first runner corresponding to the first liquid outlet and a second runner corresponding to the second liquid outlet; the first runner is used for enabling a liquid that enters the liquid inlet and is higher than a preset hydraulic value to flow out from the first liquid outlet; and the second runner is used for enabling a liquid that enters the liquid inlet and is lower than thepreset hydraulic valve to flow out from the second liquid outlet. The distribution valve for the heat pump system is simple in structure and low in cost. The valve element is pushed to move as a result of different pressures of fluids at the inlet and the outlet of the valve body to reverse a refrigerant fluid, so that the heat pump system can meet refrigerating and heating demands of a power battery by using one heat exchange core body. The distribution valve has huge advantages in whole vehicle arrangement space, weight of parts and cost.

    本申请公开了一种用于热泵系统的分配阀,包括阀体和阀芯;阀体的第一端设有进液口,阀体的第二端设有第一出液口,阀体的侧壁设有第二出液口;阀芯设置于阀体的内腔中,阀芯包括与第一出液口对应的第一流道和与第二出液口对应的第二流道;第一流道用于使进入进液口的高于预设液压值的液体从第一出液口流出,第二流道用于使进入进液口的低于预设液压值的液体从第二出液口流出。本申请的用于热泵系统的分配阀结构简单、成本低,通过阀体进出口流体的压力不同,推动阀芯移动,实现制冷剂流体换向,使得热泵系统采用一个换热芯体即可实现动力电池的制冷和制热需求,在整车布置空间、零件重量和成本上均有很大优势。
