    • An apparatus for imparting suitable buoyancy to submerged articles, such as pipelines, to reduce their weight in water and enable efficient movement thereof. The apparatus comprises at least one float comprising air tight material, pipe for supplying pressurized air thereinto, and a differential pressure regulating valve arranged close to the float and connectable to the pipe for regulating the amount of pressurized air supplied to the float dependent upon the difference in pressure between that in the float and a predetermined value. Advantageously, the apparatus is easily transportable, stored and attached to the items to which it imparts the desired amount of buoyancy; the apparatus also keeps constant the buoyancy regardless of the depth of water, thus, enabling easy and safe moving of submerged articles.
    • 对于诸如管道之类的浸没物品赋予适当的浮力的装置,以减少其在水中的重量并使其能够有效地移动。 该装置包括至少一个浮子,其包括气密材料,用于向其中供应加压空气的管道以及靠近浮子设置的可连接到管道的差压调节阀,用于调节供应给浮子的加压空气量,这取决于差异 在浮子中的压力和预定值之间。 有利地,该装置易于运输,储存和附接到其赋予所需量的浮力的物品; 无论水深如何,该设备也保持恒定的浮力,从而能够容易且安全地移动浸没的物品。
