CONNECTION STRUCTURE OF WATER SYSTEM PIPING
To provide a connection structure for connecting pipes without brazing in the piping of a bathroom, a sink, a toilet, a feed water tank or a water supply meter having a possibility of coming into contact with water.SOLUTION: A connection structure of water system piping has an adapter body having a male screw part with a stepped part of a smaller diameter and a larger diameter on the outer circumference of a through-hole for inserting a bend pipe related to the connection, and a fastening ring screwable with the larger diameter screw part provided to the adapter body. Another coupling related to the connection has a female screw part screwable with the smaller diameter male screw part of the adapter body on an inner peripheral surface thereof. The adapter body is screw-fitted with the coupling via a seal member set between a flange part formed at an end part of the bend pipe and a wall face part of the female screw side, to thereby water-tightly fix both.SELECTED DRAWING: Figure 1
【課題】風呂場、シンク、トイレ、給水タンク、給水メータ等の水と接触し得る配管において、ロウ付けしないで配管接続するための接続構造を提供する。【解決手段】接続に係わる曲管を挿通する貫通孔の外周に小径と大径の段違い雄ネジ部を設け、前記大径雄ネジ部に前記曲管の外径よりも若干広く切り欠いた切り欠き部を設けたアダプタ−本体と、前記アダプタ−本体に設けた大径雄ネジ部と螺合可能な締付リングを備え、接続に係わる他方の継手にはその内周面に前記アダプタ−本体の小径雄ネジ部に螺合可能な雌ネジ部を備え、前記曲管の先端部に形成した鍔部と前記雌ネジ部側の壁面部との間にシール部材を介して前記アダプタ−本体と継手を螺合締着することによって水密に固定する。【選択図】図１
