GAS VESSEL BY SYSTEM IN WHICH GAS EXPANSION IN MEMBRANE ROOF BY USING GAS IS CONTROLLED NATURALLY

摘要

PURPOSE: To reduce the change of membrane tension by forming a recessed section at the proper section of a cylindrical gas sealed vessel mounted into a roof and largely expanding the recessed section with gas expansion. ;CONSTITUTION: This gas vessel is composed of cylindrical gas sealed vessels 1 as main body vessels 1 and high elastic rings 2 consisting of a material having high elasticity, and parts or a plurality of sections of the drum sections of the gas sealed vessels 1 are clamped by the high elastic rings 2 having small radii. Accordingly, the rings having diameters smaller than the diameters of the cylindrical gas sealed vessels are fitted, and a material having elasticity higher than vessel bodies is used for the rings, thus quickly controlling a large quantity of gas expansion and contraction in a natural adjusting manner by the ring sections. The rings 2 are expanded rapidly in response to the expansion of a gas in the vessels 1 due to the rise of an atmospheric temperature to inhibit the sudden increase of internal pressure, and the excess augmentation of the diameters of the vessels is prevented.;COPYRIGHT: (C)1996,JPO
