The invention provides an elastic pressing type multi-channel electromagnetic valve. The elastic pressing type multi-channel electromagnetic valve comprises a valve element assembly, a valve seat assembly, a sealing unit and a power unit. The valve seat assembly comprises a valve seat and a valve deck, openings in the two ends of the valve seat are provided with first containing cavities, the valve deck covers the openings, and the valve element assembly and the sealing unit are located in the first containing cavities. The valve element assembly comprises a valve element body and a retainer. The valve element body is provided with a plurality of channels which are distributed in the circumferential direction of the valve element body at intervals and extend in the axial direction of the valve seat. The retainer is connected with the valve core body; the sealing unit comprises a sealing ring and an elastic piece, the sealing ring is provided with a plurality of through holes and connected with the valve seat, and the elastic piece is connected with the valve element body and the retainer; and the power unit is connected with the retainer and drives the valve core body to rotate, so that at least one channel is opposite to the through hole in the sealing ring to form a circulation passage of cooling liquid. Through the structural design, the valve element body and the sealing ring are kept abutting against each other, flowing of cooling liquid in a circumferential gap between the valve element body and the valve seat is reduced, and the sealing performance of the valve body is improved.

    本申请提供的弹压式多通路电磁阀,包括阀芯组件、阀座组件、密封单元和动力单元;阀座组件包括阀座和阀盖,阀座两端开口具有第一容置腔,阀盖盖设于开口,阀芯组件和密封单元位于第一容置腔;阀芯组件包括阀芯本体和止动件,阀芯本体具有沿着其周向间隔分布且沿阀座轴向延伸的多个通道;止动件和阀芯本体连接;密封单元包括密封环和弹性件,密封环具有多个通孔,密封环和阀座连接,弹性件连接阀芯本体和止动件;动力单元和止动件连接并驱动阀芯本体转动,使至少一个通道和密封环上的通孔相对形成冷却液的流通通路。通过这种结构设计,使阀芯本体和密封圈保持抵接,减少冷却液在阀芯本体和阀座周向间隙的流动,提高了阀体的密封性能。
