This utility model discloses an electronic valve and a
refrigeration device, relating to the field of
refrigeration control technology. The electronic valve includes a valve body, a valve needle
assembly, and a guide sleeve. The valve body has a valve cavity, a connecting port, and a
valve port communicating with the valve cavity. The valve needle
assembly includes a mounting base and a valve needle. The mounting base is fixedly connected to the valve body, and the valve needle movably passes through a mounting hole in the mounting base to open and close the
valve port. The guide sleeve is fixedly installed inside the valve cavity, located on the side of the mounting base facing the
valve port and spaced apart from the mounting base. The guide sleeve has a guide hole for the valve needle to pass through. By placing the guide sleeve on the side of the valve needle
assembly near the valve port, not only is the movement of the valve needle guided, but the
impact area of the
refrigerant on the valve needle head is also reduced, thereby reducing the
vibration amplitude of the valve needle and thus reducing the resulting
noise. The spaced arrangement between the guide sleeve and the mounting base makes the assembly of the guide sleeve independent of the positional accuracy of the valve needle assembly, simplifying the assembly process and reducing manufacturing difficulty.
