Abstract
The protective device prevents overheating, in particular by fire, of individual or batteries of pressure vessels of length equal to at least 1,5 m, employed for storage and/or transportation of gases under high pressure. The essentially cylindrical pressure vessels have at least one closure cap with a valve or a closure plug. Mounted on one closure cap is a pressure pipe which communicates with the interior of the pressure vessel, and is fitted with a controllable venting valve that under normal conditions closes off the pressure pipe or a common pressure pipe and has a venting pipe which terminates outwith the region of the pressrue vessel/vessels. Temperature sensitive actuating means are provdied in the axial direciton of the pressure vessel/vessels a spacing apart and connected to the venting valve. These means can individually actuate the venting valve should overheating occur.
