Abstract

The invention discloses an electronic expansion valve, a refrigerating system and an automobile, the electronic expansion valve comprises a valve seat and a valve body assembly, the valve seat is provided with a valve core seat, and the valve core seat is provided with a valve core cavity and a valve port communicated with the valve core cavity; the valve body assembly comprises a connecting seat, a bearing and a valve element assembly, the connecting seat is connected with the valve seat, a mounting groove is formed in the connecting seat, and the bearing is mounted in the mounting groove; the valve element assembly penetrates through the connecting base and the bearing to be inserted into the valve element cavity so as to open and close the valve port. And the bearing is in interference fit with the connecting seat. According to the technical scheme, the number of parts of the electronic expansion valve is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic expansion valves, in particular to an electronic expansion valve, a refrigeration system and an automobile. Background technique [0002] In the related art, the bearing of the electronic expansion valve needs to be fixed by other fixing parts to avoid displacement. This leads to a large number of parts of the electronic expansion valve, which increases the production cost and is not conducive to the miniaturization of the electronic expansion valve. Contents of the invention [0003] The main purpose of the present invention is to provide an electronic expansion valve, aiming at reducing the number of parts of the electronic expansion valve. [0004] In order to achieve the above object, the electronic expansion valve proposed by the present invention includes a valve seat and a valve body assembly, the valve seat is provided with a valve core seat, and the valve core seat has a valve core ...
