Deposit of liquefied gas with rupture means for the inflating of watertight compartments and bag for the sealing of conduits for cables that incorporates said tank

摘要

Liquefied gas tank with easy machining and speed to actuate and bag for sealing cable ducts that incorporates said tank. The tank has breaking means for the inflation of watertight compartments that is composed of a main tube (1) closed on one side, an outlet tube (4) inserted on the other side of the main tube by a first end (6) and closed at its distal end, where the outlet tube is provided with a constriction (5) that defines a breaking point and an interior hole (8) that extends from the first end of the outlet tube to the constriction (5) towards the distal end and where the dimension of the constriction (5), that of the hole (8) and the length of the outlet tube (4) are determined such that a lever force between 19N and 80N causes the rupture of the tube outlet (4) at the breaking point (5), releasing the liquefied gas through the orifice (8).
