ABSTRACT:
A pressure sensitive exposion barrier which is activated by a static pressure rise. A liquid tight housing with a latched door contains the explosive suppression agent, usually water, until activation takes place. Upper hinges on the door allow it to be pivoted outwardly and its agent released. Normally a latch keeps the door locked until the pressure rise from the explosion causes a connected bellows assembly to be depressed. Once depressed, the latch is released and the door is forced outwardly by a biasing member to release the agent before the explosion arrives.
