Pressure vessel outlet control device.

摘要

The device comprises a push-rod (26) which works a pin (30) which cooperates with the relief stem (T) of the valve, said push-rod being mounted in a sleeve (40) with which it can be made mechanically integral via a retractable ball coupling (38), the sleeve (40) itself being mounted slidably in a casing (10) which contains a concentric chamber (16) in the line of action of the relief stem (30) and is pierced by vent holes (18) to allow an outflow of the gaseous fluid contained in the vessel (E) whose pressure is to be reduced, said vent holes (18) being formed in the side wall (17) of the casing which defines said chamber (16). <IMAGE>
