Abstract
The utility model relates to a self-operated emergency cutoff valve which is combined with three shutoff modes of electromagnetism, manual operation and temperature sensing self-operation. A manually pressing handle drives a temperature sensing element to push an ejector rod to move downwards; the temperature sensing element is affected by the ambient temperature to push the ejector rod to move downwards; the ejector rod drives a protective sliding block, a reduced pressure protection spring and a small ejector rod to slide downwards; an inner steel ball fixing piece is pressed by the small ejector rod to move downwards; the steel ball enters a gap between a ball-clamping connecting piece and the inner steel ball fixing piece; and after the ball-clamping connecting piece is used for reducing the obstruction of the steel ball, the ball-clamping connecting piece, the sealing piece and a sealing tablet simultaneously move downwards to shut off the valve under the action of the sealing spring. When the ambient temperature of the self-operated emergency cutoff valve abnormally rises to a preset temperature, the self-operated emergency cutoff valve can be shut off automatically or manually. Meanwhile, the self-operated emergency cutoff valve can be remotely shut off through electric control as required.
