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 nut is mounted on the valveseat. The connecting piece is mounted on the nut. The connecting piece comprises a connecting part and a reinforcing part, one end of the connecting part is fixed to the nut, the other end of the connecting part is fixedly connected with the valve seat, at least part of the reinforcing part is fixed to the nut, and the connecting part and the reinforcing part are connected by forming an included angle. According to the technical scheme, in the electronic expansion valve, the nut is mounted on the valve seat, the connecting piece is mounted on the nut, the connecting piece comprises the connecting part and the reinforcing part, one end of the connecting part is fixed to the nut, the other end of the connecting part is fixedly connected with the valve seat, and therefore the function of fixedly connecting the nut and the valve seat is achieved. The reinforcing part and the connecting part are connected by forming the included angle so as to achieve the function of enhancing the strengthof the connecting piece, meanwhile, at least part of the reinforcing part is fixed in the nut, the connecting strength of the connecting piece and the nut is enhanced, and then the effect of improvingthe stability of the mounting structure of the nut and the valve seat is achieved.

Description

technical field [0001] The invention relates to the technical field of fluid control components, 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, there is a problem of poor structural stability between the nut and the valve seat. Contents of the invention [0004] The main purpose of the present invention is to provide an electronic expansion valve, aiming to solve the problem of poor structural stability between the nut and the valve seat in the prior art. [0005] In order to achieve the above object, the electronic expansion valve proposed by the present i...
