BRECKENRIDGE BLAST-ACTUATED CLOSURE VALVE

Abstract

The ventilation systems of shelters providing blast protection must have automatic valves to prevent ingress of damaging pressure waves through the air ducts. This report discusses a blast-actuated closure valve developed, tested, and evaluated at the U. S. Naval Civil Engineering Laboratory. For ventilation the valve has a rated airflow of 700 cfm. It provides protection from blast overpressures up to 150 psi. It also provides protection during the negative phase following any blast wave. When installed as intended, the valve should be relatively insensitive to the thermal pulse and ground accelerations associated with nuclear explosions. It is also insensitive to environmental conditions. Its operation is simple and reliable, and resetting is unnecessary because of the valve's automatic response. It requires no maintenance.
