Gas tap comprising an electromagnetic safety valve and magnetic insert for an electromagnetic safety valve

摘要

A gas tap including a gas path includes an electromagnetic safety valve for closing the gas path is provided. The safety valve includes an armature housing and having a mobile magnetic anchor in the housing and a valve seat. The mobile magnetic anchor includes a valve closing element which presses on the valve seat to close the gas path and an electromagnetic coil for activating the mobile magnetic anchor and the valve closing element to close the gas path when voltage is applied to the electromagnetic coil. Also, the electromagnetic coil is arranged as a separate component outside of the armature housing on a magnetic insert.
