Problems solved by technology
During the working process of the solenoid valve, the electromagnetic coil is energized to generate electromagnetic suction to attract the core iron. The movement of the core iron drives the valve stem, valve core and other components to move, and the valve port is opened or closed. When the solenoid valve is working, the medium pressure in the valve body changes greatly. , the electromagnetic suction is affected by it, so that the traditional solenoid valve can only achieve one-way work, and the sealing form determines the directional sealing of the solenoid valve. The specified flow direction of the medium can realize its function, which limits the application of solenoid valves
For this reason, a two-way solenoid valve that can realize forward or reverse flow of the medium has been disclosed in the prior art, but its structure is complicated, the assembly is difficult, and the cost is high

The invention discloses an electromagnetic valve, and belongs to the technical field of electromagnetic valves. The electromagnetic valve solves the technical problem that at present, a double-direction electromagnetic valve is complex in structure. The electromagnetic valve comprises a valve seat, a valve element component and a pilot valve component. A valve opening is formed in the valve seat, and the pilot valve component drives the valve element component to move; internal space of the valve seat is divided into an upper cavity, a middle cavity and a lower cavity; the valve opening comprises an upper valve opening body, a middle valve opening body and a lower valve opening body; the upper valve opening is formed between the upper cavity and the middle cavity, and the middle valve opening body is formed between the middle cavity and the lower cavity; the lower valve opening body is formed in the portion, corresponding to the middle valve opening body, of the valve seat; the pilot valve component controls the upper valve opening to be opened and closed; the valve element component controls the middle valve opening body and the lower valve opening body to be opened and closed; and the upper cavity is communicated with the lower cavity through a fluid channel. The electromagnetic valve is mainly applied to fluid direction control of a pipeline system.
Description
【Technical field】 [0001] The invention relates to a solenoid valve, in particular to a two-way solenoid valve capable of realizing medium forward or reverse flow. 【Background technique】 [0002] Solenoid valves are widely used in the pipelines of refrigeration systems such as air conditioners and refrigerators to control the on-off of refrigerant. During the working process of the solenoid valve, the electromagnetic coil is energized to generate electromagnetic suction to attract the core iron. The movement of the core iron drives the valve stem, valve core and other components to move, and the valve port is opened or closed. When the solenoid valve is working, the medium pressure in the valve body changes greatly. , the electromagnetic suction is affected by it, so that the traditional solenoid valve can only achieve one-way work, the sealing form determines the directional sealing of the solenoid valve, that is to say, the solenoid valve must ensure that there is a positiv...
