Description

Valve electromagnet for pressure container

Technical Field

The utility model relates to a solenoid valve technical field, especially a valve electromagnet of pressure vessel.

Background

The electric pressure cooker ensures no loss of nutrition in food because of full-sealed cooking and no-boiling cooking; the high-pressure cooking can effectively decompose fat and cholesterol and release nutrient components in food more comprehensively, so that the high-pressure cooking becomes a common cooking utensil in modern life. Because the electric pressure cooker needs to be fully sealed and used for cooking food at high pressure, the electric pressure cooker generally has pressure regulation changes of multiple grades such as normal pressure, low pressure, high pressure and the like, in the existing design, the pressure change is realized by matching and regulating the electromagnet and the magnetic valve, namely, the pressures of different grades can provide several magnetic forces by regulating the current in the electromagnet and the magnetic valve are matched with each other to achieve the effect of regulating the pressure.

The insulation mode between the iron core and the wire winding of the existing electromagnetic valve is generally realized by adopting enameled wires and insulating adhesive tapes, the electromagnetic valve on the electric pressure cooker is easily invaded by water vapor, so that the insulation performance is reduced, and the water vapor can also cause the iron core to generate corrosion to influence the service life of the electromagnetic valve. In order to solve the problem, in the published patent CN217108437U, there are some improvements in that a shielding cover is disposed inside the valve body, and the shielding cover surrounds the iron core, the keel and the coil assembly, and the iron core, the keel and the coil assembly are integrally encapsulated by the valve body to prevent water vapor from corroding the coil assembly. Because the keel is arranged on the iron core by adopting the injection molding process, the valve body is coated on the end surface spacing part and the circumferential spacing part of the shielding cover by the secondary injection molding integrated molding. Because the physical properties of the metal material and the nonmetal material are different, the nonmetal material is easy to wrinkle and warp at the joint of the nonmetal material and the metal material under a high-temperature environment. The in-process that the iron core was moulded plastics at fossil fragments and valve body injection moulding cladding is in the production process of shield cover, because location and ejecting technological requirement, iron core and shield cover can partially expose outside, and the valve body or fossil fragments that combine rather than in the periphery of exposed part are non-metallic material, and non-metallic material corrugates easily and sticks up the skin under high temperature environment, makes high pressure steam from corrugating and stick up skin infiltration coil assembly, and then influences the function and the life of electro-magnet.
