Document Type and Number:
WIPO Patent Application WO/2020/181922
Kind Code:
A1
Abstract:
An electronic expansion valve and a refrigeration system. The electronic expansion valve comprises: a valve base (10) having an inlet (11), an outlet (12) and a communication channel (13) in communication with the inlet (11) and the outlet (12); an actuating mechanism (20) movably installed within the valve base (10), wherein the actuating mechanism (20) can move to a first position to block the communication channel (13) or move to a second position to avoid the communication channel (13); and a driving mechanism (30) connected to and driving the actuating mechanism (20) to move between the first position and the second position, wherein the driving mechanism (30) comprises noise reduction members (1-33, 1-34, 2-33, 2-34, 3-33, 3-34) used to reduce noise of the electronic expansion valve. The refrigeration system comprises a liquid storage container, an evaporator and the electronic expansion valve. The electronic expansion valve can solve the problem in the art in which an electronic expansion valve produces much noise.
