[0033] The second embodiment is a local change made on the basis of the first embodiment, which is mainly reflected in the structural design of the small-diameter section of the moving iron core part. The difference between this embodiment and the first embodiment is that when the coil part 1 is not energized , the solenoid valve is in the open state, and when the coil part 1 is energized, the solenoid valve is in the closed state.

[0034] The structure of this embodiment will be described below in conjunction with the accompanying drawings, and the components with the same structure and function as those of the first embodiment will be described with the same numbers.

[0035] Please refer to image 3 , image 3 It is a structural schematic diagram of the second embodiment of the direct-acting two-way solenoid valve of the present invention. In this embodiment, a fluid channel 273 is also opened above the radial through hole opened by the small-diameter section 271 . When...

Abstract

The invention provides a direct-actuating bidirectional solenoid valve, comprising a valve body, a sleeve fixedly connected with the valve body, coils arranged outside the sleeve, a movable iron core, a static iron core and a return spring arranged between the movable iron core and the static iron core, wherein the movable iron core and the static iron core are arranged in the sleeve; and the valve body is provided with valve chambers and a valve port. The solenoid valve is characterized in that at least a pair of planes is arranged on the inner walls of the valve chambers and is parallel with each other. The solenoid valve can conveniently realize the control of the bidirectionally flowing refrigerant by arranging the valve chambers with symmetric plane structures and adopting sealing components arranged at the end of the movable iron core to control the valve port to open and close, and has the advantages of simple structure. In addition, the direct-actuating bidirectional solenoid valve provided by the invention can be used as a pilot valve in the large-diameter bidirectional solenoid valve and serves as the main component for realizing the large-diameter bidirectional solenoid valve.

Description

technical field [0001] The invention relates to a solenoid valve for refrigerant control used in air conditioners, refrigerators and other devices, in particular to a direct-acting two-way solenoid valve which is suitable for both forward and reverse flow of refrigerant and can be actuated. Background technique [0002] Direct-acting solenoid valves are widely used in the pipelines of refrigeration systems such as air conditioners and ice machines to control the on-off of refrigerant. The current relatively common direct-acting solenoid valve structure, such as the patent "Solenoid Valve" with the publication number CN101498379A, discloses a typical solenoid valve used in refrigeration systems, including a valve seat and a sleeve connected to the valve seat and The coil outside the casing, the valve seat has a valve port and is fixed with a medium inlet pipe and an outlet pipe. There is a static iron core and a moving iron core inside the casing. A spring is arranged between...
