Description

本発明は水道栓の蛇口内に着脱自在に設ける流量調整用節水こまに関するものである。   The present invention relates to a water-saving top for adjusting a flow rate that is detachably provided in a faucet of a water tap.

従来、蛇口内に装着する流量調整用節水こまでは、内筒の側壁に通水孔を穿設し、該通水孔の上縁以下の内筒外周と外筒内周との間に、流水量を調整するために細隙を設け、該細隙から水を流下させることにより、流速が早くなり相当多量の水量が放出されているようにし、かつ内筒の一端にフランジを設け、これを水道栓の開口部に当接し、さらに蛇口の基端を該フランジに当接し、袋ナットで締付けて蛇口及び上記内筒を水道栓に着脱自在に装着した（例えば特許文献１，２）
ところで水道栓の開口部外径に対し、上記フランジの外径が小であると、水道栓と上記内筒との中心が偏位し、締付け弛み時に該内筒に振動を生じるおそれがあった（特許文献１，２）。 Conventionally, up to a water-saving flow control pad installed in the faucet, a water passage hole is formed in the side wall of the inner cylinder, and the water flow between the inner cylinder outer circumference and the outer circumference of the outer cylinder below the upper edge of the water passage hole. A slit is provided to adjust the amount, and water is allowed to flow down from the slit to increase the flow velocity so that a considerable amount of water is discharged, and a flange is provided at one end of the inner cylinder. Abutted against the opening of the water tap, and further, the base end of the faucet was brought into contact with the flange, and the faucet and the inner cylinder were detachably attached to the water faucet by tightening with a cap nut (for example, Patent Documents 1 and 2)
By the way, when the outer diameter of the flange is smaller than the outer diameter of the opening of the water tap, the center of the water tap and the inner cylinder is displaced, and there is a risk that the inner cylinder may vibrate when loosened. (Patent Documents 1 and 2).

第３に上記外筒の外周にゴム等の可撓弾性パッキングを嵌装し、該パッキングの外周を蛇口管の内周に密着させる上記第１又は第２発明記載の蛇口流量調整装置における節水こま、
によって構成される。 In order to achieve the above object, according to the present invention, firstly, a diameter-enlarged portion for fitting an outer cylinder is formed on the outer circumference of one end of a short cylinder opened at both ends, and a flange is provided at the end of the enlarged diameter part. In the faucet flow rate adjusting device in which the inner circumference of one end of the pipe is fitted to the outer circumference of the enlarged diameter section, the outer cylinder is extended from the other end of the short cylinder, and a water flow guide plate is provided at the extended end of the center line of the short cylinder. and provided at right angles, the center portion of the water flow guide plates are opposed with a gap to the other end opening of the short tube, the outer peripheral portion of the water flow guide plate is integrally connected to the extended end, the water flow guide The plate is provided with a plurality of spokes at a point-symmetrical position in the center thereof, and the outer ends of the spokes are integrally welded to the extended ends, and the spokes are formed on both sides with arc-shaped edges, A plurality of arc-shaped water through holes are formed in the outer periphery of the water flow guide plate by the inner periphery of the outer tube, and the other end of the short tube The water discharged from the water flow guide plate hits the central portion of the water flow guide plate, changes its direction radially in the horizontal direction, and immediately diverts downward from the plurality of water passage through-holes at point symmetry positions, and immediately without diverting the water flow. The water-saving in the faucet flow control device is configured to be able to flow in a delayed manner from the inner surface of the extended end portion of the outer cylinder into the arc-shaped water passage after flowing horizontally on the upper surface of the spoke. Top,
Secondly, a water-saving top in the faucet flow control device according to the first aspect of the present invention, wherein a water passage hole having an arcuate edge is formed in three directions of the guide plate.
Thirdly, a flexible elastic packing made of rubber or the like is fitted on the outer periphery of the outer cylinder, and the outer periphery of the packing is in close contact with the inner periphery of the faucet tube. ,
Consists of.

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.

上記外筒は外周の可撓弾性パッキングによって蛇口の内周にがたなく保持され、水道栓の上記開口部と中心線を共有することができる。   The outer cylinder is held in the inner periphery of the faucet by the flexible elastic packing on the outer periphery, and can share the center line with the opening of the water tap.

本発明は上述のように構成したので、
水道栓の開口部から排出される水は中心線に沿って短筒内を流下し、間隙内を上記案内板の中央部から放射状に横向に流動し、上記外筒の延長部内面から直ちに下向きに分流するものと、遅れて下向に分流するものと時差合流し、流線が乱れ、又水道栓内の水圧が上昇すると流速が速くなり、上記案内板附近の流水は乱流となるが、
上記内外筒の振動はなく静粛に蛇口から排出され得る。 Since the present invention is configured as described above,
The water discharged from the opening of the water faucet flows down in the short cylinder along the center line, flows radially in the gap from the center of the guide plate, and immediately downwards from the inner surface of the extension of the outer cylinder. However, when the water pressure in the water tap rises, the flow speed increases and the water near the guide plate becomes turbulent. ,
The inner and outer cylinders do not vibrate and can be silently discharged from the faucet.

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 diameter portion 4 for fitting an outer cylinder is formed on the outer circumference of one end side of the short cylinder 1 having both ends 2 and 3 open, and a flange 6 is provided at the end of the enlarged diameter portion 4.

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 diameter portion 4 are inserted into the heated outer cylinder 5 up to the lower surface of the flange 6, and the outer cylinder 5 is cooled and contracted in this state, whereby the outer cylinder is formed on the outer peripheral surface of the enlarged diameter portion 4. The inner peripheral surface of 5 is integrally fitted.

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 flange 6 protrudes outward from the outer periphery of one end of the outer cylinder 5, and in the state where the flange 6 is in contact with the opening end peripheral surface 11 ′ of the water tap 11, the inner diameter w of the short cylinder 1 is A faucet flow rate adjusting device is formed because it is smaller than the inner diameter W of the opening.

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 outer cylinder 5 extends from the other end of the short cylinder 1 in the direction of the center line c, and a water flow guide plate 7 is provided integrally with the extension end 5 'in a direction perpendicular to the center line c.

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 guide plate 7 has a central portion 7 'opposed to the other end opening 3 of the short cylinder 1 via a gap t, and a plurality (three) of spokes 7 ", 7" at a point-symmetrical position with respect to the central portion 7'. , 7 ″, and the outer ends of the spokes 7 ″, 7 ″, 7 ″ are integrally welded to the extended end 5 ′, and the arc-shaped edges 8 ′ on both sides of the spokes 7 ″, 7 ″, 7 ″. , 8 ', point-symmetrical arc-shaped water-permeable through holes 8, 8, and 8 are formed. A plurality of spokes 7 "and through-holes 8 such as 2 to 6 are sufficient.

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 flange 6 is generally smaller than the outer peripheral diameter of the opening end peripheral surface 11 ′ of the water tap 11 and there is a difference in diameter, when contacting the flange 6 to the opening end peripheral surface 11 ′ as shown in FIG. The center line of the opening does not necessarily coincide with the center line c of the flange 6 or the short cylinder 1.

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 faucet tube 10 is inserted along the outer periphery of the outer cylinder 5 as shown in FIG. 1, the base end flange 10 ′ is in contact with the flange 6, and the base end flange 10 ′ is connected to the cap nut 12. Then, the two flanges 6 and 10 'are removably supported on the opening end peripheral surface 11' by being screwed to the outer peripheral spiral 11 "of the opening.

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 cap nut 12, there is no possibility that the short tube 1 vibrates due to the flow force.

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 elastic packing 9 such as rubber on the outer periphery of the outer cylinder 5, the outer periphery of the packing 9 is brought into close contact with the inner periphery of the base end portion of the faucet tube 10, and the opening end peripheral surface of the water tap 11 The center line of 11 'and the short cylinder 1 can be a common center line c, and even if the opening diameter W and the inner peripheral diameter w of the short cylinder 1 are different, the short cylinder 1 is vibrated by water. It disappears.

発明を実施するための上記状態において上記フランジ６の外径１５ｍｍ、短筒１の高さ１０ｍｍ、外径８ｍｍ、内径ｗ３ｍｍ、外筒５の高さ１２ｍｍ、間隙ｔ２ｍｍでステンレス鋼によって形成され、上記パッキング９の高さは短筒１の高さに一致させ又は短筒の高さよりも短く形成することができる。   In the above-described state for carrying out the invention, the flange 6 is formed of stainless steel with an outer diameter of 15 mm, a short cylinder 1 having a height of 10 mm, an outer diameter of 8 mm, an inner diameter of 3 mm, an outer cylinder 5 having a height of 12 mm, and a gap t2 mm. The height of the packing 9 can be made to coincide with the height of the short cylinder 1 or shorter than the height of the short cylinder.

本発明では水道栓の開口部に袋ナットで着脱自在に接続する蛇口管の基端内部に短筒及びその外筒よりなる蛇口流量調整装置を装着し、それに上記節水こまを静然と配設し得るばかりでなく該節水こま内において水流及び水圧の乱れを発生し、節水流を活性化することができる。   In the present invention, a faucet flow adjustment device comprising a short cylinder and its outer cylinder is mounted inside the base end of the faucet pipe which is detachably connected to the opening of the water tap with a cap nut, and the above water-saving top is quietly disposed on it. Not only can the water flow and water pressure be disturbed in the water-saving top, but the water-saving flow can be activated.
