Abstract:
An electric valve, comprising a nut assembly (5), a valve seat assembly (4), and a sleeve (6). The nut assembly comprises a plastic part (51) and a connecting portion (52); the connecting portion is fixed to the plastic part; the material of the connecting portion is a metal material; the sleeve is fixedly connected to the connecting portion; the connecting portion comprises a lower end face portion (522); the valve seat assembly comprises a first end portion (47); the material of the first end portion is a metal material; the first end portion is fixed to the lower end face portion by means of welding. According to the electric valve, the sleeve is fixedly connected to the connecting portion, and the first end portion of the valve seat assembly is fixed to the lower end face portion by means of welding, so that the valve seat assembly works in conjunction with the connecting portion without machining an additional mating structure, thereby reducing the machining costs of the electric valve.
