[0002] Solenoid valves are divided into direct-acting solenoid valves and pilot-operated solenoid valves. Direct-acting solenoid valves mainly use an electromagnet to push the moving iron core to control the flow of fluid. It generates a magnetic field by energizing the coil, thereby generating an electromagnetic force of mutual attraction between the moving iron core sealing assembly and the static iron core in the solenoid valve, opening the solenoid valve and allowing the medium to flow through the solenoid valve.

[0011] Preferably, a flow port is provided inside the solenoid valve body.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] (1) The direct-acting sealed solenoid valve can fix the connecting pipe more stably through the reinforcement ring, making it less likely for the connecting pipe to loosen. The sealing gasket on the reinforcement ring can prevent liquid from flowing out of the gap between the solenoid valve body and the connecting pipe, further enhancing the sealing performance of the solenoid valve, extending the maintenance cycle, and saving time.
