By adopting the structure, the invention has the beneficial effects that: the invention adopts the mode that the rubber plug penetrates through the through hole of the movable iron core to connect the rubber plug with the movable iron core, and because the maximum cross section of the plug head and the maximum cross section of the plug head are larger than the maximum cross section of the plug column, the stretching part of the rubber plug is required to be pulled when the valve core is produced, the plug head is forced to penetrate through the through hole of the movable iron core, at the moment, the plug head is clamped at the stepped shaft end of the movable iron core, the plug head is clamped at the lower end of the movable iron core, and the stretching part of the rubber plug is sheared after connection is completed. The invention omits the step of dispensing, not only improves the production efficiency and ensures the health of workers, but also ensures that the rubber plug is more firmly connected with the movable iron core.
The plug is preferably a cone since it is the main constituent of the closed solenoid valve passageway. Compared with other three-dimensional shapes, the cone has good sealing performance, meanwhile, the stress area of the cone is small, and the cone is not easy to damage during working.
Further as a preferred embodiment, a circular groove is arranged at the lower end of the movable iron core, and the central axis of the circular groove coincides with the central axis of the movable iron core through hole.
