Micro electromagnetic valve

Abstract

The invention discloses a micro electromagnetic valve which comprises an electromagnetic coil, a movable iron core, a valve body and a plunger tube, wherein the electromagnetic coil comprises a magnetizer, a flux sleeve, a magnetic shield and a coil; the upper end of the movable iron core is sleeved with a spring, the lower end of the movable iron core is sleeved with a diaphragm, the cost of parts is reduced by removing a fixing iron core. When the movable iron core is absorbed, the top end of the movable iron core does not contact with the inner bottom of the plunger tube; the noise is removed; and the production cost is reduced. A sealing chamber is formed by the plunger tube and the valve body; the plunger tube and the valve are sealed by a sealing ring; the valve body is connected with the plunger tube in a riveting way, so that complexes of the threaded connection are reduced. Copper foam and scrap iron generated by threaded connection are avoided. The electromagnetic valve coil is connected with the plunger tube by a snap spring; the valve body and the electromagnetic valve coil are tightly resisted, so that the angle of the electromagnetic coil can be freely adjusted as required without shaking the adjusted angle, therefore, greater space can be selected on connection; and the micro electromagnetic valve is more flexible to use.

Description

Technical field [0001] The present invention involves a type of solenoid valve, especially a miniature solenoid valve. Background technique [0002] At present, due to the upgrade of small home appliances, the steam volume and steam calories generated by the original electromagnetic pump water spraying to the heating board cannot meet the requirements.The heat -calorie small appliances become the inevitable of modern technology, and to achieve the above performance, it is necessary to be a compact, high -temperature and high -pressure solenoid valve.However, there is no structural compact, high -temperature and high -voltage solenoid valve in the existing steam solenoid valve. [0003] China Patent Announcement Number CN201071959Y. On June 11, 2008, a valve body, a coil component and a safety slider component were released. There are two built -in air cavity spaces on the valve body.There are penetration holes, and the coil components consist of the mid -vacant column coil, fixin...
