<p>An electric valve and a refrigeration system comprising the electric valve. The electric valve comprises a valve base (1), a casing (2), and a cover (3) that connects the valve base (1) and the casing (2). The cover (3) is disposed outside the valve base (1) through a central through hole (31) of the cover (3). The cover (3) is disposed with a first guiding portion (32) fit with the casing (2). The cover (3) further comprises a transitional connection portion (33) disposed with the central through hole (31). The first guiding portion (32) is bent downwards with respect to the transitional connection portion (33), an outer side wall of the first guiding portion (32) is attached to an inner wall of the casing (2), and a lower end portion of the first guiding portion (32) is fixedly connected to a lower end portion of the casing (2). Through the design of the structure of the electric valve, the material cost can be reduced, the axiality between the casing (2) and the cover (3) can be increased, and the heat quantity required when the cover (3) and the casing (2) are welded can be reduced.</p> |
