<p>PURPOSE:To provide a resistance against earthquake in an LPG tank by adopting a simple structure in which interior membrane is extended to a roof and a pipe nozzle is inserted through a sleeve penetrated therethrough the supported on the side by a membrane anchor. CONSTITUTION:Heat-insulating materials 15 are provided on the outer tank 12 of an LPG tank 11, and interior membrane is extended to cover a part of a roof 16. A sleeve 17 is provided to penetrate through heat-insulating materials 15 and the membrane 13 from the roof 16, and a pipe nozzle is inserted therethrough and euipped with a pump 23 on its lower end. Thermal displacements of the sleeve 17 and the membrane 13 are both absorbed by expansion 19 provided with a bellows 18 on the lower end of the sleeve. The pipe nozzle 22 is supported on the side by supporting members fixed on a membrane anchor 24. This construction serves to keep a high resistance against earthquake is spite of a suspended roof construction.</p> |
