Abstract
Provided is an electric valve, including a valve seat and a valve needle, and the valve needle is mounted in the valve seat; a valve core, which is mounted at an end of the valve seat, and the valve core forms a valve opening; a driving assembly, which drives the valve needle to axially move so as to open and close the valve opening; the valve core is made of a non-metal material, an inner wall or an end face of the valve core forms a sealing face, and the sealing face and an outer wall face of the valve needle form a soft sealing structure. Through the soft sealing structure composed of the valve core and the valve needle, the technical problem of poor sealing performance of the electric valve can be solved.
