Hermetic door and procedure for the monitorable hermetic sealing of elements which close openings

摘要

The design of large-surface-area hermetic doors and procedure for closing and for monitoring the hermetic sealing of elements which close openings and are intended for use in nuclear power stations, shelters and the like. The room seal has to ensure a monitorable functional reliability regardless of how often it is used. Procedure which can be monitored and performed in a simple manner. Various use conditions for large openings and passageways for people. Closing and sealing mechanisms which can be operated from both sides, irrespective of the number and arrangement of door leaves. Test pressure is built up without an additional medium and allows actual hermetic-sealing conditions to be monitored at any time. Door leaves are arranged such that they can move in at least two different directions with respect to a case. By virtue of a combination of locking mechanisms and sealing bodies and profiles, into which an examinable medium is enclosed, they form a hermetic seal. After a number of positional changes in the movement directions of door leaves with respect to one another and with respect to a case and their subsequent locking, the procedure automatically indicates the superatmospheric pressure, present in the seals, on monitoring devices. <IMAGE>
