Background
The existing electronic expansion valve is generally controlled by a stepping motor to regulate the flow of a refrigerant, and comprises a driver (the stepping motor), an actuating mechanism (a thread pair), a throttling mechanism (a valve needle valve port) and related auxiliary mechanisms. The stator coil of the stepping motor receives a pulse signal provided by the controller to drive the rotor magnetic ring to rotate, and the rotor magnetic ring (integrated with the mandrel screw) rotates to drive the valve needle (integrated with the mandrel screw) to move up and down axially, so that the through-flow sectional areas of the valve needle and the valve port are controlled to adjust the refrigerating capacity, and the efficiency of the evaporator is matched.
The valve port and the valve seat of the existing electronic expansion valve are pressed together in an interference manner, or the valve seat and the valve port are of an integrated structure. The valve port is not easy to be detached from the valve seat, which is not beneficial to the analysis of failure parts; different customers have different demands on the refrigerating capacity, so valve ports with different specifications are needed, and the valve port form is not beneficial to product standardization.

Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 and 2, an embodiment of the present invention includes:
a valve port structure easy to assemble and disassemble is applied to an electronic expansion valve 1. The valve port structure includes: the valve port body 13 is detachably and fixedly arranged on the valve seat 11 of the electronic expansion valve. The valve seat 11 is provided with a mounting hole for mounting the valve port body 13, and the inner side wall of the mounting hole is provided with internal threads. The valve port body 13 is provided with an overflowing hole 130 for matching with the valve needle 12 of the electronic expansion valve; the outer side wall of the valve port body 13 is provided with an external thread matched with the internal thread so as to be in threaded connection with the valve seat 11; the lower end of the valve port body 13 is provided with a circle of boss 131, the outer diameter of the boss 131 is larger than the inner diameter of the mounting hole, the upper end surface of the boss 131 can abut against the upper end surface of the lower end surface of the valve seat 11 to form a stop surface 132, the lower end surface of the boss 131 is flush with the lower end surface of the valve port body 13, and the valve port is simple in overall structure and convenient to machine.
