Claim 0:
1. An electronic expansion valve, comprising a valve body, a valve core, a rotor assembly, a stator assembly and a circuit board, wherein the stator assembly is located on an outer circumference of the rotor assembly, and the stator assembly is electrically connected to the circuit board;
the electronic expansion valve has a valve port, and the valve core is configured to move with respect to the valve port to adjust an opening degree of the valve port;
the valve body comprises a first flow portion and a second flow portion, at least part of the first flow portion is located above the valve port, and at least part of the second flow portion is located below the valve port;
the valve body has a first cavity and a second cavity, the first cavity is located above the valve port, and the second cavity is located below the valve port, the first flow portion is in communication with the first cavity, and the second flow portion is in communication with the second cavity;
the first flow portion comprises a first connection section and a first subsection, the first connection section is configured to connect with an external connection pipe, and the first subsection is in direct communication with the first cavity;
the second flow portion comprises a second connection section and a second subsection, the second connection section is configured to connect with an external connection pipe, and the second subsection is in direct communication with the second cavity;
in a center line of the first subsection, part of the center line located in the first subsection is defined as a first line, and in a center line of the second subsection, part of the center line located in the second subsection is defined as a second line;
a first cross section is obtained by cutting the electronic expansion valve along a section plane which passes through a center line of the valve core, wherein flow paths of a working medium in the first flow portion and the second flow portion lie in the first cross section, and on the first cross section, an angle clockwise formed between at least one of the first line and the second line and the center line of the valve core is an acute angle.
