Title: ELECTRONIC EXPANSION VALVE AND REFRIGERATION SYSTEM HAVING SAME
Abstract:
An electronic expansion valve and a refrigeration system having the same. The electronic expansion valve comprises: a valve body (10); a valve needle (20), movably disposed in the valve body (10); a driving part (30), driving the valve needle (20) to move; a control part (40), electrically connected to an external device through a lead wire (50) to control the action of the driving part (30); and a first insulation structure (60), located at a joint of the control part (40) and the lead wire (50), and isolating the joint from the driving part (30). The electronic expansion valve can effectively address the problem in the prior art that the electronic expansion valve is vulnerable to lightning phenomenon.
