An electric valve, comprising a lead screw and a valve element assembly, wherein the lead screw has an external thread section, the valve element assembly has an internal thread section, the valve element assembly and the lead screw are in threaded connection by the fitting of the internal thread section and the external thread section, and at least the portion of the valve element assembly corresponding to the internal thread section is made of a material including a plastic material. Due to the portion of the valve element assembly corresponding to the internal thread section being made of a material including a plastic material, compared with two metal parts, a lead screw and a valve element being in direct threaded connection, the thread wear is reduced, and the service life of the electric valve is prolonged.

Electric valve

An electric valve and an assembly method therefor. The provision of multilayered sealing of a first sealing element, a second sealing element, and a sealing medium located between the first sealing element and the second sealing element along the axial direction of a valve stem is conducive to restricting outward leakage of a fluid along the axial direction of the valve stem.
