Abstract

The invention relates to an electromagnetic valve. The electromagnetic valve comprises a valve body component and an electromagnetic coil, wherein the electromagnetic coil is fixedly arranged on the valve body component; the valve body component comprises a guiding valve, a valve seat and a valve body which are fixedly connected to one another hermetically; and a valve element component is slidably arranged in the valve seat and is in compaction connection with the valve seat through a second elastic component. When the electromagnetic valve is closed, a first valve opening of the valve element component is sealed by an end of the guiding valve in a compaction manner; a second valve opening in the valve body is sealed by the valve element component in a compaction manner; the inner diameter of the second valve opening is greater than that of the first valve opening; and when the electromagnetic coil of the electromagnetic valve is electrified, the guiding valve is separated from the first valve opening, and pressure difference is formed between an upper end surface and a lower end surface of the valve element component, the valve element component upwards moves under the action of the second elastic component and the height pressure difference, and the second valve opening is opened. The electromagnetic valve has the advantages that the flow resistance of fluid in the electromagnetic valve is low, the work noise is greatly reduced, and the weight of the electromagnetic valve is also reduced.

Description

technical field [0001] The invention relates to a flow control component, and more specifically, relates to a solenoid valve for controlling the flow of refrigerant in the technical field of refrigeration. Background technique [0002] In the field of refrigeration technology, solenoid valves are refrigerant flow control components of refrigeration equipment. Its working process is generally as follows: With the power on or off of the coil, the solenoid valve is opened or closed in the refrigeration equipment system such as the air conditioner, thereby controlling the circulation or interruption of the refrigerant. Of course, the application field of the solenoid valve is not limited to the above-mentioned refrigeration technology field, for example, it is also widely used in the hydraulic technology field. [0003] Existing solenoid valves have large internal fluid flow resistance, irregular flow tracks, and relatively high flow noise, which reduces user comfort. Content...
