Abstract

The problem underlying the present invention is that of providing a safety shut-off for gas lines in which the valve body bed is frictionless and maintenance-free and which presents only a minimum flow resistance. In addition, the safety shut-off is to do without any outside seal. It is to be easily fitted and capable of installation in existing gas lines without fittings or any alteration thereto. The problem is solved in that, in a safety shut-off for gas lines with a valve body (6) which can be pressed against a valve seat (1), in which the valve body (6) is fitted to be movable in the axial direction of the valve seat (1) against the force of a closing spring, the valve body is guided only by a spring and is otherwise free to move without any additional seating. The invention relates to a safety shut-off to close gas lines in the event of damage, e.g. pipe breakages or tears in hoses, to prevent the uncontrolled escape of gas and hence avoid any danger.
