Installation pour le remplissage d'un récipient comprenant un appareil pour empêcher un débordement de liquide lors du remplissage

摘要

A pneumatically operated overspill prevention system to close a control valve in a liquid supply line if a liquid level sensor mounted in a container being filled responds to a predetermined liquid level. The system includes a pneumatically extensible member mounted in linkage between the valve and a conventional preset meter with the linkage collapsing and the valve automatically returning to a closed position in the event the sensor detects an excessive liquid level. The entire system is pneumatic and is failsafe in that the valve automatically opens in the event of failure of the compressed air supply of the control assembly.
