Abstract
The invention takes as its basis the problem of creating a safety sealing device for gas pipes by which the bearing of the valve body should be frictionless, require no maintenance and which causes only minimal flow resistance. Further the safety sealing device should not require outward sealing connections. It should be easy to install and able to be fitted into existing gas piping or fittings without having to change them.
The problem is solved in that with safety sealing devices with a valve body (6) which can be pressed against a valve seat (1), whereby the valve body (6) is supported so that it is movable in the axial direction of the valve seat (1) is against the force of a locking spring (8), the valve body is conducted only through a spring and is otherwise freely movable without additional support points.
The invention concerns a safety sealing device for closing gas conduits in cases of damage, e.g. pipe bursts or hose ruptures, in order to prevent an uncontrolled leakage of gas and thereby a dangerous situation.
