Description

本発明は、水源から供給される水または水溶液を誘導して吐出させる導水管に関する。 The present invention relates to a water conduit for guiding and discharging water or an aqueous solution supplied from a water source.

導水管の一形式として、所定の径寸法の導水通路を有する導水管本体の先端部に、所定の径寸法の導水通路を有するノズルを備え、基端部にて水源に接続されて、水源から供給される水または水溶液を、導水管本体の導水通路およびノズルの導水通路に導入して、ノズルの先端開口部から吐出させる導水管ある。当該形式の導水管は、通常、ノズルの導水通路の径寸法は、導水管本体の導水通路の径寸法より大きく設定されている（特許文献１を参照）。
特開２００５−２４０９５１号公報 As one type of water guide pipe, a nozzle having a water guide passage with a predetermined diameter is provided at the distal end of a water guide pipe body having a water guide passage with a predetermined diameter, and is connected to a water source at a base end portion. There is a water conduit that introduces water or an aqueous solution to be introduced into a water conduit of the water conduit main body and a water conduit of the nozzle, and discharges the water from the tip opening of the nozzle.

JP-A-2005-240951

ところで、当該形式の導水管においては、上記したように、ノズルの導水通路の径寸法が、導水管本体の導水通路の径寸法より大きく設定されていることから、水源から供給される水や水溶液（以下水等ということがある）は、導水管本体の比較的細い導水通路を経て、そのままの勢いで、ノズルが有する比較的太い導水通路に流入することになる。このため、水等が導水管本体の導水通路からノズルの導水通路に移行する際には、水勢が強い場合には、強い水勢に起因して水流が乱れ、水等がノズルから吐出する際には周囲に飛び散ることになる。従って、本発明の目的は、このような問題に対処することにある。 By the way, in the water conduit of this type, as described above, the diameter of the water guide passage of the nozzle is set larger than the diameter of the water guide passage of the water conduit main body. (Hereinafter sometimes referred to as water or the like) flows into the relatively thick water guide passage of the nozzle through the relatively narrow water guide passage of the water conduit main body. For this reason, when water or the like is transferred from the water guide passage of the water guide pipe body to the water guide passage of the nozzle, if the water force is strong, the water flow is disturbed due to the strong water force, and water or the like is discharged from the nozzle. Will be scattered around. Accordingly, an object of the present invention is to address such problems.

本発明は、導水管に関する。本発明が適用対象とする導水管は、所定の径寸法の導水通路を有する導水管本体の先端部に、同導水管本体の導水通路より大きい径寸法の導水通路を有するノズルを備え、基端部にて水源に接続されて水源から供給される水または水溶液を、前記導水管本体の導水通路および前記ノズルの導水通路に導入して、同ノズルの先端開口部から吐出させる導水管である。 The present invention relates to a water conduit. The water guide pipe to which the present invention is applied includes a nozzle having a water guide passage having a diameter larger than the water guide passage of the water guide pipe body at the distal end portion of the water pipe main body having a water guide passage having a predetermined diameter. This is a water conduit that is connected to a water source at the section and is supplied from the water source to the water guide passage of the water conduit main body and the water guide passage of the nozzle, and is discharged from the tip opening of the nozzle.

しかして、本発明に係る導水管においては、前記ノズルは、同ノズルの導水通路に、前記導水管本体の導水通路を通って流入する水または水溶液の流動を規制して前記導水通路の径外方へ飛散させる遮蔽部と、同遮蔽部にて飛散した水または水溶液を前記ノズルの導水通路の軸方向へ整流して吐出させる整流部を備えていることを特徴とするものである。 Thus, in the water conduit according to the present invention, the nozzle regulates a flow of water or an aqueous solution flowing into the water guide passage of the nozzle through the water guide passage of the water guide main body so as to be outside the diameter of the water guide passage. And a rectifying unit that rectifies and discharges water or an aqueous solution splashed by the shielding unit in the axial direction of the water guide passage of the nozzle.

本発明に係る導水管においては、前記ノズルを、同ノズルの導水通路を径方向に複数に区画する複数の区画壁部を一体に備えるととに、同区画壁部の上流側部位に前記ノズルの導水通路の略中央部に位置して前記導水管本体の導水通路を通って流入する水または水溶液と対向する遮蔽板部を一体に備える構成とすることができ、かかる構成により、前記遮蔽板部が前記遮蔽部を構成し、かつ、前記各区画壁部が前記整流部を構成するようにすることができる。この場合、前記各区画壁部を十字状態に組合わせ、前記ノズルの導水通路に位置させるようにすることが好ましい。 In the water conduit according to the present invention, the nozzle is integrally provided with a plurality of partition walls that divide the water guide passage of the nozzle into a plurality of portions in the radial direction, and the nozzle is provided at an upstream portion of the partition wall. A shielding plate portion that is positioned substantially at the center of the water guide passage and faces the water or aqueous solution flowing through the water guide passage of the water guide pipe body, and is configured to be integrated with the shielding plate. A part may constitute the shielding part, and each partition wall part may constitute the rectifying part. In this case, it is preferable that the partition walls are combined in a cross shape and positioned in the water guide passage of the nozzle.

本発明に係る導水管においては、導水管本体の導水通路に比較して径寸法が大きいノズルの導水通路に、導水管本体の導水通路を通って流入する水等の流動を規制して導水通路の径外方へ飛散させる遮蔽部と、同遮蔽部にて飛散した水等をノズルの導水通路の軸方向へ整流して吐出させる整流部を備える構成としていることから、ノズルの先端開口部から吐出する水等は、その吐出の前においては、ノズルの導水通路での水流は水勢が抑制されて整流状態となり、水等がノズルの先端開口部から吐出する際に、周囲への飛散は大きく抑制されることになる。 In the water conduit according to the present invention, the flow of water or the like flowing through the water conduit of the water conduit main body is regulated in the water conduit of the nozzle having a larger diameter than the water conduit of the water conduit main body. From the tip opening of the nozzle, it is configured to include a shielding part that scatters outward of the diameter of the nozzle, and a rectifying part that rectifies and discharges water scattered in the shielding part in the axial direction of the water guide passage of the nozzle. Prior to the discharge of the water to be discharged, the water flow in the water guide passage of the nozzle is in a rectified state with the water flow suppressed, and when water or the like is discharged from the tip opening of the nozzle, scattering to the surroundings is large. Will be suppressed.

本発明に係る導水管において、ノズルの導水通路に一体的に設けた、ノズルの導水通路を径方向に複数に区画する複数の区画壁部にて整流部を構成し、各区画壁部の上流側部位に設けた遮蔽板部にて遮蔽部を構成すれば、また、この場合、各区画壁部を十字状態に組合わせた状態で整流部を構成すれば、ノズルの導水通路内での遮蔽部および整流部の機能を一層効果的に発揮させることができる。 In the water conduit according to the present invention, the rectification unit is configured by a plurality of partition wall portions that are integrally provided in the water guide passage of the nozzle and divide the water guide passage of the nozzle into a plurality of radial directions, and upstream of each partition wall portion. If the shielding part is constituted by the shielding plate part provided in the side portion, and in this case, if the rectification part is constituted in a state where the partition wall parts are combined in a cross shape, the shielding in the water guide passage of the nozzle is performed. The function of the section and the rectifying section can be more effectively exhibited.

And a nozzle 30 connected to the distal end side pipe joint 20a.

管本体１０は、蛇腹状のフレキシブルチューブ１１、フレキシブルチューブ１１を貫通するインナチューブ１２、および、フレキシブルチューブ１１の外周を覆蓋する薄肉状のアウタチューブ１３にて構成されている。管本体１０を構成する各チューブ１１〜１３は、いずれも、合成樹脂からなる可撓性のチューブであって、管本体１０は、フレキシブルな管本体である。当該管本体１０の各端部に嵌合している先端側管継手２０ａおよび基端側管継手２０ｂは、実質的には同一構成のものである。従って、管継手の構成および管本体１０の各端部に対する取付構造については、先端側管継手２０ａを例として説明する。 The tube body 10 includes a bellows-like flexible tube 11, an inner tube 12 that penetrates the flexible tube 11, and a thin outer tube 13 that covers the outer periphery of the flexible tube 11. Each of the tubes 11 to 13 constituting the tube body 10 is a flexible tube made of a synthetic resin, and the tube body 10 is a flexible tube body. The distal end side pipe joint 20a and the proximal end side pipe joint 20b fitted to each end of the pipe body 10 have substantially the same configuration. Therefore, the structure of the pipe joint and the mounting structure for each end of the pipe body 10 will be described by taking the distal end side pipe joint 20a as an example.

先端側管継手２０ａ（以下単に管継手２０ａということがある）は、円筒体をその中心軸に沿って２分割されてなる互いに類似する形状の一対の半円筒体２１，２２と、互いに接合された状態の半円筒体２１，２２の外周に嵌合するジョイントカバー２３にて構成されている。当該管継手２０ａにおいては、半円筒体２１，２２は管本体１０の先端部の外周に外側から嵌合（外嵌）して円筒体を形成していて、当該円筒体にジョイントカバー２３を外嵌することにより、管本体１０の先端部に取付けられている。当該管継手２０ａは、後述する本発明の主要部をなすノズル３０を、管本体１０の先端部に接合すべく機能する。ノズル３０は、半円筒体２１，２２の内孔周面に形成されているねじ部に螺着することにより、管本体１０のインナチューブ１２の先端に挿着してある筒状の連結管１４を介して、インナチューブ１２に接続されて連結されている。 The distal end side pipe joint 20a (hereinafter sometimes simply referred to as the pipe joint 20a) is joined to a pair of semi-cylindrical bodies 21 and 22 having a similar shape obtained by dividing the cylindrical body into two along its central axis. It is comprised by the joint cover 23 fitted to the outer periphery of the semi-cylindrical bodies 21 and 22 of the state which it was. In the pipe joint 20a, the semi-cylindrical bodies 21 and 22 are fitted (externally fitted) to the outer periphery of the distal end portion of the pipe body 10 to form a cylindrical body, and the joint cover 23 is removed from the cylindrical body. By fitting, it is attached to the tip of the tube body 10. The pipe joint 20 a functions to join a nozzle 30 that forms a main part of the present invention, which will be described later, to the tip of the pipe body 10. The nozzle 30 is screwed into a threaded portion formed on the peripheral surface of the inner hole of the semi-cylindrical bodies 21 and 22, so that the cylindrical connecting pipe 14 inserted into the tip of the inner tube 12 of the pipe body 10. Are connected to and connected to the inner tube 12.

ノズル３０は、本発明の主要部をなすもので、図２および図３に示すように、ノズル３０の導水通路内に、同導水通路に流入する水流に対する遮蔽部および整流部を備えていることを特徴とするものである。当該ノズル３０を構成するノズル本体３１は円筒体であって、内孔は導水通路３１ａに形成されている。導水通路３１ａは、管本体１０の導水通路１２ａであるインナチューブ１２の内孔より大径であって、ノズル本体３１の導水通路３１ａの径寸法は、管本体１０の導水通路１２ａの径寸法に比較して、大きく設定されている。 The nozzle 30 forms the main part of the present invention, and as shown in FIGS. 2 and 3, the nozzle 30 includes a shielding portion and a rectifying portion for the water flow flowing into the water guide passage in the water guide passage of the nozzle 30. It is characterized by. The nozzle body 31 constituting the nozzle 30 is a cylindrical body, and the inner hole is formed in the water guide passage 31a. The water guide passage 31 a has a larger diameter than the inner hole of the inner tube 12 that is the water guide passage 12 a of the pipe body 10, and the diameter dimension of the water guide passage 31 a of the nozzle body 31 is the same as the diameter dimension of the water guide passage 12 a of the pipe body 10. In comparison, it is set larger.

当該ノズル３０は、それ自体、合成樹脂にて成形されているもので、ノズル本体３１の導水通路３１ａの中間部には、十字状態に交差する４枚の区画壁部３２がノズル本体３１と一体に形成されている。また、各区画壁部３２が互いに交わる位置の上流側部位には、円板状の遮蔽板部３３が各区画壁部３２と一体に形成されている。遮蔽板部３３は、管本体１０のインナチューブ１２の内孔が形成する導水通路１２ａからノズル本体３１の導水通路３１ａに流入する水流に対向して位置し、また、各区画壁部３２は遮蔽板部３３の下流側にて導水通路３１ａを径方向に４分割してなる各整流路部Ｐを形成している。 The nozzle 30 itself is formed of a synthetic resin, and four partition wall portions 32 intersecting with a cross shape are integrated with the nozzle body 31 at an intermediate portion of the water guide passage 31 a of the nozzle body 31. Is formed. In addition, a disc-shaped shielding plate portion 33 is formed integrally with each partition wall portion 32 at an upstream portion where the partition wall portions 32 intersect each other. The shielding plate portion 33 is located opposite to the water flow flowing from the water guide passage 12a formed by the inner hole of the inner tube 12 of the pipe body 10 into the water guide passage 31a of the nozzle body 31, and each partition wall portion 32 is shielded. Each rectifying path portion P is formed on the downstream side of the plate portion 33 by dividing the water guide passage 31a into four in the radial direction.

当該ノズル３０においては、その導水通路３１ａに備えている遮蔽板部３３は、管本体１０のインナチューブ１２の内孔が形成する導水通路１２ａからノズル３０の導水通路３１ａに流入する水流に対向しているため、ノズル３０の導水通路３１ａに、図３の矢印で示すように流入する水流の流動を規制して水勢を弱めるとともに、弱めた水流を導水通路３１ａの径外方へ飛散させる。このように水勢を弱めらて飛散する水流は、各区画壁部３２が形成する各整流路部Ｐを流動する間に整流されて、図３の矢印に示すように流出し、ノズル３０の先端開口部から吐出する際には、周囲に飛散することなく、整流された流れとして円滑に吐出することになる。 In the nozzle 30, the shielding plate portion 33 provided in the water guide passage 31 a faces the water flow flowing from the water guide passage 12 a formed by the inner hole of the inner tube 12 of the pipe body 10 into the water guide passage 31 a of the nozzle 30. Therefore, the flow of the water flow flowing into the water guide passage 31a of the nozzle 30 is regulated to weaken the water force, and the weakened water flow is scattered outward in the diameter of the water guide passage 31a. In this way, the water flow scattered by weakening the water flow is rectified while flowing through each rectifying path portion P formed by each partition wall portion 32, flows out as shown by the arrow in FIG. When discharging from the opening, it is smoothly discharged as a rectified flow without scattering around.
