Description

Technical Field

[0001] The utility model relates to the technical field of electromagnets, in particular to an electromagnet for a large-flow threaded cartridge valve. Background Art

[0002] An electromagnet is a device that generates electromagnetic force when powered on. After an iron core is inserted into the coil, the iron core is magnetized by the magnetic field of the coil. The DC electromagnet actuator is installed in a metal shell, and the electrical signal is connected to the control system through a cable. A direct current is passed through the exciting coil, and a magnetic field with a fixed magnitude and direction is generated by the direct current passing through the exciting coil, generating a magnetic force to cause the moving component assembly to move, and the movement of the moving component assembly causes the actuator to move.

[0003] However, in some existing electromagnets applied in large-flow hydraulic systems, the electromagnet must be able to withstand a relatively high system pressure. Therefore, the pressure resistance and other factors will be considered in the structure and material selection. At the same time, the power consumption is relatively large, and a large amount of heat is generated when the high-power electromagnet works. It is impossible to dissipate heat well under some high-strength structures, thus affecting the service performance and life. At the same time, in the application of some electromagnets in the flow threaded cartridge valve, due to the differences in the sizes of the threaded matching parts, some electromagnets are usually equipped with standard or customized threaded interfaces that cannot be satisfied, there are certain limitations, so it needs to be solved.
