Problems solved by technology

[0003] In the prior art, a combination of a single hole throttle valve port and a simple cylindrical cone valve needle structure is used to move the relative position to adjust the throttling amount, and it is difficult to adjust the throttling amount parameters at specific multi-point positions during the throttling process. Make accurate settings to optimize the system
Not to mention that in the two-way throttling system, according to the characteristics of forward throttling cooling and reverse throttling heating, different parameter designs can be carried out, which will cause a large energy loss

Abstract

The invention relates to a bidirectional throttling electronic expansion valve, and belongs to the technical field of refrigeration control. The bidirectional throttling electronic expansion valve comprises a driving mechanism (100) and an execution mechanism (200) which are controlled by virtue of signals, wherein the execution mechanism (200) comprises a valve body (3) with a first channel (34) and a second channel (35), and a valve core part arranged in a valve cavity (33) of the valve body (3), and is characterized in that the valve core part comprises a valve core (2) and a switching part (1); an inner cavity (24), as well as a positive throttling channel (21) and a negative throttling channel (22) which are communicated with the inner cavity (24) are formed in the valve core (2); and the switching part (1) is arranged in the inner cavity (24) of the valve core (2). According to the bidirectional throttling electronic expansion valve, structures of throttling parts of the positive throttling channel and the negative throttling channel can be designed independently according to optimized data required by a refrigeration system; and the bidirectional throttling electronic expansion valve has a simple and reliable structure, and the heat utilization efficiency for refrigeration or heating can be improved.
