Problems solved by technology

[0003] At present, in the production process of the existing solenoid valve core, glue is often used to bond the rubber plug and the two ends of the moving iron core. This production process is not only inefficient, but also affects the health of workers.
In actual use, the rubber plug is prone to degumming, which makes the solenoid valve not work properly.

Abstract

The invention discloses a valve element of a magnetic valve. The valve element of the magnetic valve comprises a moveable iron core and a rubber plug. The moveable iron core, along a length direction,is provided with a moveable iron core through hole. One end of the moveable iron core is provided with a moveable iron core stepped shaft. The rubber plug comprises a plug head, a plug column, a stopper and a stretching part. Each of the maximum cross section of the plug head and the maximum cross section of the stopper is greater than the maximum cross section of the plug column. The maximum cross section of the stretching part is smaller than the maximum cross section of the plug column. The plug column is matched with the moveable iron core through hole. According to the valve element of the magnetic valve, the rubber plug is connected with the moveable iron core by using a mode that the rubber plug passes through the moveable iron core through hole, the stretching part of the rubber plug needs to be pulled while the valve element is produced, the stopper is forced to pass through the moveable iron core through hole, at this moment, the stopper is locked and connected at the moveable iron core stepped shaft end, and the plug head is locked and connected at the other end of the moveable iron core. The valve element of the magnetic valve is capable of eliminating a dispensing step, improving production efficiency, guaranteeing the health of a worker, and enabling the connection between the rubber plug and the moveable iron core to be firmer.

Description

technical field [0001] The invention relates to the field of valves, in particular to a valve core of an electromagnetic valve. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator and is not limited to hydraulic and pneumatic. Solenoid valves are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. At the same time, solenoid valves can cooperate with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed regulating valves. [0003] At present, in the production process of the existing solenoid valve core, glue is of...
