WATER SERVICE PIPE CRACK FRACTURE PREVENTION DEVICE
To solve problems of a conventional crack fracture prevention device for a water service pipe 4 due to freezing such that a device cost is high in the electric system, it does not work at the time of a power failure, it requires a construction technology and material deterioration is troublesome in a method of wrapping a heat insulating material around the water service pipe 4, and there are economical or hygiene problems in other methods.SOLUTION: Provided is a crack fracture prevention device of the water service pipe 4 in which a branch pipe is attached to a branch portion provided in the middle of the water service pipe 4, an air reservoir tank 9 is attached upwardly at one end by being integrated with an object having a conical lower part and a cylindrical upper part made of a resin material, the whole surface of an upper part of the air reservoir tank 9 is opened, a lid 11 is provided in the opening, and a water drain cock 8 is attached to a branch pipe 7 for water drain provided in the lower part of the air reservoir tank 9.SELECTED DRAWING: Figure 1
【課題】従来の凍結による水道配管４の亀裂破戒防止装置は、電気方式では装置費が高く付き、停電時に不能となり、水道配管４に断熱材を巻きつける方法では施工技術を要し材料劣化が難点で、その他の方法も経済性や衛生面で課題があった。【解決手段】本発明は水道配管４の途中に設けた分岐部に分岐管を取り付け、その一端に上向きに樹脂製の材質で製作した上部円筒形で下部円錐形の形状のものを一体化し空気溜タンク９を取り付け、前記空気溜タンク９の上部は全面開口とし、その開口にフタ１１を設け、更に空気溜タンク９の下部に設けた水抜き用分岐管７に水抜き用コック８を取り付けた水道配管４の亀裂破壊防止装置。【選択図】図１
