Automatically resealable, fluid tight anti-burst device on pressure less containers such as steel oil tanks has sealing component rigidly connected to guide, and locking device which prevents guide from emerging from container mouth

摘要

The automatically resealable, fluid tight anti-burst device on pressure less containers consists of a sealing component (1) with a seal (3) at the mouth of the container, with the sealing component rigidly connected to a guide (2) which protrudes into the mouth of the container. The sealing component has a locking device (5,6,7) which prevents the guide from emerging from the container mouth. The sealing component has a weight which at the latest during pressure test of the container induces an opening of the container mouth by positional change of the sealing component.
