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.
