Abstract

The invention discloses an electric valve. The electric valve comprises a valve body, a valve seat, a sliding block and a driving device. The valve body is provided with a first connecting port, a second connecting port and a third connecting port; the valve seat is fixed into the valve body and provided with a first through hole and a second through hole, the first through hole is one part of a flowing passage formed between the first connecting port and the third connecting port, and the second through hole is one part of the a flowing passage formed between the second connecting port and the third connecting port; the sliding block is located in the valve body and slidably matched with the valve seat, and when the sliding block rotates relative to the valve seat, the condition that thefirst through hole is completely covered and the second through hole communicates with the third connecting port, or the first through hole and a part of the second through hole are synchronously covered, or the second through hole is completely covered and the first through hole communicates with the third connecting port can be realized; and the driving device drives the sliding block to rotate.The structural design of the electric valve can effectively simplify the design of a pipeline.

Description

technical field [0001] The invention relates to the technical field of refrigeration parts, and more specifically, relates to an electric valve. Background technique [0002] In an air-conditioning system, two solenoid valves are usually used as control components to change the refrigerant flow path, so as to realize the switching between cooling and heating modes. However, for vehicle-mounted air conditioners, the space in the vehicle is limited, and the two solenoid valves not only take up a lot of space, but also complicate the control method and air-conditioning pipeline design. [0003] To sum up, how to effectively simplify pipeline design is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides an electric valve, the structural design of which can effectively simplify pipeline design. [0005] In order to achieve the above object, the present invention provides the following t...
