A simplified, pressure-variation preventing tank structure capable of preventing pressure variations in a gas phase portion resulting from temperature variations, without bringing stored liquid into contact with air. This pressure-variation preventing structure includes a breather bag (3) arranged in a gas phase portion (2) of a tank (1) and inflating/deflating in communication with outside air, and a manhole (21) to which the breather bag is attached to suspend in a gas phase portion, including a communication hole (22) for the breather bag to communicate with outside air. The breather bag (3) has air-blocking, acid-resistant and expandable characteristics.
L'invention concerne une structure de réservoir de prévention de fluctuations de pression facilitée qui permet d'empêcher une fluctuation de pression dans une partie en phase gazeuse résultant d'une variation de température sans que le liquide stocké vienne au contact de l'air. Ladite structure comprend des sacs (3) de respiration installés dans la partie en phase gazeuse (2) du réservoir (1) se dilatant et se contractant en communication avec l'atmosphère et des regards (21) munis de trous de communication (22) permettant aux sacs de respiration de communiquer avec l'atmosphère, et auxquels lesdits sacs sont fixés de façon à être suspendus à la partie en phase gazeuse. Lesdits sacs de respiration (3) sont en outre étanches à l'air, résistants aux acides et extensibles.
