The invention discloses a soft-sealing large-flow valve element assembly of a reversing valve. The valve element assembly comprises a liquid returning valve sleeve, a valve base, a liquid inlet valvesleeve, a valve element and a pressing rod assembly movably arranged in the liquid returning valve sleeve, the pressing rod assembly comprises a pressing rod body and a valve cushion arranged on the pressing rod body and used for being in contact with the valve element for sealing, and the valve cushion is made of soft materials. According to the soft-sealing large-flow valve element assembly of the reversing valve, by arranging the valve cushion made of the soft materials on the pressing rod body to cooperate with the valve element for sealing, the pressing rod body does not need to cooperatewith the valve element for sealing, and there is no need to process a sealing surface on the pressing rod body so that the structure and processing technology of the pressing rod body can be simplified; after the sealing function is unavailable in long-term use of the valve element assembly, only the valve cushion needs to be replaced, the cost is reduced, and the high reliability of sealing is ensured.
