Abstract

The invention provides an electric switching valve. The electric switching valve comprises a valve seat and a valve block, wherein the valve seat is provided with an upper end surface and is providedwith a first leading-out opening and a second leading-out opening; the valve block is provided with a coordination portion and a notch portion; the coordination portion is fit to the upper end surfaceof the valve seat and can be rotated relative to the valve seat; and the notch portion can be selectively in communication with the first leading-out opening or the second leading-out opening. The electric switching valve is characterized in that the valve block also comprises at least one throttling portion; and the interior of a channel formed by the throttling portion comprises at least one throttling orifice. The invention also provides the valve block. The valve block can be applied to the electric switching valve, and can also be applied to valves used in other refrigeration systems.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an electric switching valve used in a refrigeration cycle device. Background technique [0002] In refrigeration cycle devices, such as refrigerators, electric switching valves are usually used as control components to change the refrigerant flow path. [0003] The electric switching valve includes a valve seat and a casing fixed above the valve seat, and also includes a motor, the coil part of the motor is outside the casing, and the rotor part is built in the casing. [0004] A valve cavity is formed inside the shell, and the valve seat is provided with an inlet channel and an outlet channel, and its upper end surface has an outlet port corresponding to the outlet channel, and a slider is also arranged on the valve seat to seal and fit with the upper end surface, and the slider is on the rotor part. It rotates synchronously under the drive and cooperates with the export ...
