Description

technical field [0001] A self-operated fire valve belongs to the technical field of building fire protection equipment. technical background [0002] In recent years, many buildings have installed fire-fighting equipment, such as glass bubble sprinklers, but the existing technologies, whether domestic or foreign, are all disposable, and this disposable device, when fire After being extinguished, it still sprays water continuously, wasting a lot of water resources. content of the invention; [0003] The purpose of the present invention is to provide a self-operated fire valve. [0004] The object of the present invention is achieved in this way. There is a valve cover with a sleeve on the upper part of the valve body that enters and exits the water. In the inner cavity of the valve cover, there is a self-supporting valve core; the upper part of the valve core is inserted into the valve cavity. In the casing inside the cover, a magnet is inlaid on the upper end of the valv...
