Abstract

The invention discloses an electronic expansion valve and refrigeration equipment. The electronic expansion valve comprises a valve seat, a nut and a connecting piece. The valve seat is provided witha valve cavity, one end of the nut is installed in the valve cavity, an annular positioning part is arranged on the outer wall of the nut in a protruding manner, and the positioning part is connectedwith the cavity wall of the valve seat in an abutting manner to achieve positioning. One end of the connecting piece is fixedly connected with the nut, and the other end of the connecting piece extends away from the nut and is fixedly connected with the axial end face of the valve seat. According to the technical scheme, the electronic expansion valve achieves the function of positioning the nut and the valve seat in the axial and radial directions, the coaxiality of the nut and the valve seat is guaranteed, then the coaxiality of the nut and the valve element seat is guaranteed, the phenomenon that the electronic expansion valve gets stuck is avoided, and the working performance of the electronic expansion valve is improved.

Description

technical field [0001] The invention relates to the technical field of fluid control, in particular to an electronic expansion valve and refrigeration equipment. Background technique [0002] In air conditioners, refrigerators, heat pump water heaters and various refrigeration and heating equipment, electronic expansion valves are usually used to regulate the flow of fluid. [0003] In the related art, an electronic expansion valve usually includes a valve seat assembly, a nut assembly, and a valve needle assembly. flow function. In the prior art, when the components in the electronic expansion valve are matched, the electronic expansion valve is likely to be stuck, which affects the working performance of the electronic expansion valve. Contents of the invention [0004] The main purpose of the present invention is to provide an electronic expansion valve, aiming at solving the phenomenon that the electronic expansion valve is easily stuck in the prior art. [0005] In...
