従って上記フランジを水道栓の開口端面に当接し、蛇口管を外筒又は上記パッキングの外周に沿って中心線の方向に嵌合し、
袋ナットで上記フランジ及び蛇口管の基端フランジを締付けて該袋ナットを水道栓の外周雄ネジに螺合させる。
Therefore, the flange is brought into contact with the opening end surface of the water tap, and the faucet tube is fitted in the direction of the center line along the outer periphery of the outer cylinder or the packing,
The flange and the base end flange of the faucet tube are tightened with a cap nut, and the cap nut is screwed onto the outer peripheral male screw of the water tap.
その状態において水道栓を開いて水道水を開口部から流出させると、水は短筒内に流入し、他端から排出される。 In this state, when the tap is opened and the tap water flows out from the opening, the water flows into the short cylinder and is discharged from the other end.
排出水は上記間隙から水流案内板の中央部に当たり、横向放射状に方向を変更して対称位置にある複数(3個)の通水透孔から直ちに下向に分流し、及び直ちに分流することなく該透孔間の複数(3個)のスポークの上面を横向に流動した後、外筒延長端部内面から、その両側の上記透孔内に遅れて分流し、蛇口管の内面に沿って蛇口端から大気に排出又は吐出される。 The discharged water hits the central portion of the water flow guide plate from the gap, changes the direction radially in a horizontal direction, and immediately diverts downward from a plurality of (three) through holes at symmetrical positions, and without diverting immediately. After the upper surface of the plurality of (three) spokes between the through holes flows laterally, the outer pipe extends from the inner surface of the extended end portion into the through holes on both sides of the spoke, and then the faucet runs along the inner surface of the faucet tube. It is discharged or discharged from the end to the atmosphere.

両端を開口2,3した短筒1の一端側外周に外筒を嵌着するための拡径部4を形成し、該拡径部4の端部にフランジ6を設ける。
An enlarged
加熱した上記外筒5内に上記短筒1及び上記拡径部4を上記フランジ6の下面まで挿入し、その状態で外筒5を冷却収縮させることによって拡径部4の外周面に外筒5の内周面を一体に嵌着する。
The short cylinder 1 and the enlarged
この状態で上記フランジ6は外筒5の一端外周から外側に突出し、かつ該フランジ6を水道栓11の開口端周面11’に接した状態において、短筒1の内径wが水道栓11の開口部内径Wより小であるため蛇口流量調整装置が形成される。
In this state, the
上記外筒5は上記短筒1の他端から中心線cの方向に延長し、延長端5’に水流案内板7を中心線cと直角方向に一体に設ける。
The
上記案内板7は中央部7’を上記短筒1の他端開口部3に間隙tを介して対向させ、中央部7’に点対称位置に複数(3個)のスポーク7”,7”,7”を設け、該スポーク7”,7”,7”の外端を上記延長端5’に一体に溶着し、該スポーク7”,7”,7”のそれぞれ両側円弧形縁8’,8’に沿って点対称形の円弧形通水透孔8,8,8が穿設される。スポーク7”及び透孔8は2〜6個等の複数であれば足りる。
The
上記フランジ6の外周径は一般に水道栓11の開口端周面11’の外周径より小であり径差があるため、フランジ6を開口端周面11’に図1に示すように接する際、開口部の中心線とフランジ6又は短筒1の中心線cとは必ずしも一致しない。
Since the outer peripheral diameter of the
そこで蛇口管10の基端部の内周を外筒5の外周に沿って図1に示すように挿入し、基端フランジ10’を上記フランジ6に接し、基端フランジ10’を袋ナット12で上記開口部の外周螺旋11”に螺合させて上記両フランジ6,10’を上記開口端周面11’に着脱自在に支持する。
Therefore, the inner periphery of the base end portion of the
袋ナット12による上記締付けによって開口端周面11’と短筒1との中心線cが若干偏位しても短筒1が流勢により振動するおそれはない。
Even if the center line c between the opening end peripheral surface 11 ′ and the short tube 1 is slightly deviated by the above tightening by the
上記締付けが弛み勝手の状態では上記中心線cの若干の偏位が流勢による短筒1の振動の原因になるが、
上記外筒5の外周にゴム等の可撓弾性パッキング9を嵌装することにより、該パッキング9の外周を蛇口管10の基端部の内周に密着させて水道栓11の開口端周面11’と上記短筒1との中心線を共通中心線cとすることができ、上記開口部径Wと短筒1の内周径wが異なっても短筒1に水勢による振動を生ずるおそれはなくなる。
In the state where the tightening is loose, the slight deviation of the center line c causes the vibration of the short tube 1 due to the flow,
By fitting a flexible
