Description

本発明は、液体分配ヘッダーに関する。 The present invention relates to a liquid dispensing header.

給水ポンプなどの給水源に接続された給水管の先端から水を可及的に広い面積に噴射するために、図5に例示するように、給水管1の先端に接続して用いられるノズルヘッダー2がある。 To inject a large area as possible from the tip of water of the water supply pipe connected to a water supply source such as a water supply pump, as illustrated in FIG. 5, the nozzle header to be connected to an front end of the water supply pipe 1 2 there is. 従来のノズルヘッダー2は、1本の母管21に、その長手方向に間隔をおいて複数個のノズル22を取付けてなるものである。 Conventional nozzle header 2, to one of the substrate tube 21 is made by attaching a plurality of nozzles 22 at intervals in the longitudinal direction.

このノズルヘッダー2のいずれのノズル22からも等量の水を噴射させるためには、従来は、口径が異なるノズルを用いるか、口径の調整が可能なノズルを用い、母管21の給水管1との接続位置から近いノズルの口径よりも遠いノズルの口径を大きくすることにより、各ノズルの吐出量が等しくなるようにしていた。 To inject an equal amount of water from any of the nozzles 22 of the nozzle header 2, the prior art, either using a nozzle diameter is different, using a nozzle with adjustable diameter, the water supply pipe 1 of the substrate tube 21 by increasing the diameter of the farther the nozzle than the diameter of the nozzle near the connection position between, it was as discharge amount of each nozzle is equal. また、従来は、給水管1と母管21の内径が同じであった。 Further, conventionally, the inner diameter of the water supply pipe 1 and the header pipe 21 are the same.

特になし nothing special

従って、従来は、口径が異なるノズル22又は口径の調整が可能なノズル22を必要とするので、ノズルヘッダーが高価なものとなる問題があり、また、各ノズルの取付位置に応じた口径の設定又は調整が煩雑であるという問題があった。 Therefore, conventionally, since the diameter requires the nozzle 22 can be adjusted with different nozzles 22 or caliber, there is a problem that the nozzle header is expensive, also setting the diameter corresponding to the mounting position of each nozzle or adjustment there is a problem that is complicated.

下水処理設備の沈砂池に沈殿した土砂を一か所に集めて取り除く方法として、沈砂池の底部の中央に集砂ピットを形成するとともに、沈砂池の底面を集砂ピットの周辺が最深となるように傾斜させ、その沈砂池の両側の側壁の間において底部には主トラフを沈砂池内水流方向と平行に集砂ピットにおいて交差するように、かつ、集砂ピット側が深くなるように形成し、両側の側壁から集砂ピットの底面まで下り傾斜する面(以下、集砂ピット傾斜面という。)を形成し、さらに、沈砂池の底面に沈砂池内水流方向と直交する方向に平行に延びる多数の小トラフを形成し、さらに、主トラフ及び集砂ピット傾斜面の各上端部と、沈砂池の底面を沈砂池内水流方向に複数に区分した各領域と、集砂ピット内とに、それぞれノズルを設置して、沈砂 The precipitated sediment in the settling basin of a sewage treatment facility as a method of removing collected in one place, to form a Atsumarisuna pits in the middle of the bottom of the settling basin, the bottom of the sand basin is near Atsumarisuna pit becomes deepest is inclined so as to intersect in parallel to Atsumarisuna pits and the sand Ikeuchi water flow direction of the main trough at the bottom between the both side walls of the settling basin, and is formed so as Atsumarisuna pit side is deeper, both sides of the bottom surface to the downwardly inclined surfaces of Atsumarisuna pit from the side wall (hereinafter, referred Atsumarisuna pit inclined surface.) was formed, and further, a number of which extend parallel in a direction perpendicular to the bottom surface of the sand basin and sand Ikeuchi water flow direction forming a small trough, further comprising the upper part of the main runner and Atsumarisuna pit inclined surfaces, and each area obtained by dividing the bottom surface of the sand basin into a plurality of settling pond water flow direction, on the inside Atsumarisuna pit nozzles respectively installed, grit 内の水を排水ポンプで排出した状態(排水状態)で前記ノズルから3kg/cm 2未満の低圧力水を噴射させて沈砂池の底面に堆積した土砂を主トラフに流し、その流した土砂を集砂ピットに集め、その集めた土砂を集砂ピット内のノズルで撹拌しながら、集砂ピットに設置した揚砂ポンプにより水と共に汲み上げて汚水沈砂池に移送する低圧集砂方式の除砂方法が、特許文献1に記載されている。 Flowing water sediment deposited on the bottom of the settling basin by injecting a low pressure water of less than 3 kg / cm 2 from the nozzle in a state of being discharged at drain pump (drainage state) of the inner to the main runner, the flow sediments collected Atsumarisuna pit, while stirring the collected sediment in the nozzles Atsumarisuna the pit, removing sand method of the low-pressure collecting sand method of transferring the dirty water settling basin pumped together with water by Agesuna pump installed in Atsumarisuna pit There is described in Patent Document 1.

上記低圧集砂方式の除砂方法を実施する沈砂池においては、沈砂池の底面に堆積する土砂を流すために、沈砂池の底面を複数の領域に区分し、各領域の沈砂池を形成する側壁の近傍であって沈砂池の上位にノズルヘッダーを取付けている。 In the sand basin for carrying out the removal sand method of the low-pressure collecting sand method, in order to flow the sediment deposited on the bottom surface of the sand basin, it divides the bottom surface of the sand basin into a plurality of regions, forming a settling basin for each area It is attached to the nozzle header in the vicinity of the side wall to the upper sand basin. その場合、沈砂池底面の土砂を満遍なく効率的に流すことができるように、各ノズルからの吐出量は等しいことが望まれる。 In that case, so as to be able to flow evenly efficiently sediment settling basin bottom, the discharge amount from each nozzle it is desired equal. また、そのノズルヘッダーは、沈砂池の底面の全面から土砂を流す必要があることから、沈砂池の側壁になるべく近い位置に設置できることが望まれるので、ノズルヘッダーの母管はできるだけ細いことが求められる。 Moreover, the nozzle header, it is necessary to flow the sediment from the entire bottom surface of the sand basin, since it is desired that can be installed at a position as close as possible to the side wall of the settling basin, the main pipe of the nozzle headers required that as small as possible It is.

図5に示すように、母管21の給水管1との接続位置の両側に口径が同一のノズル22を等数取付けたノズルヘッダー2を、母管21の長手方向中央において母管と内径が等しい給水管1に接続し、その給水管1を給水源(図示せず)に接続した場合は、給水源からの水は、給水管1及び母管21の中を流れる間に摩擦により圧力を損失する。 As shown in FIG. 5, the nozzle header 2 diameter on either side of the connection position between the water supply pipe 1 of the substrate tube 21 is mounted equal number of the same nozzle 22, the main pipe and the inner diameter in the longitudinal center of the substrate tube 21 equal to connect to the water supply pipe 1, when connected to the water supply pipe 1 to a water supply source (not shown), the water from the water source, the pressure by friction while flowing through the water supply pipe 1 and header pipe 21 loss. 沈砂池に設置する場合の要望に応じて母管21を細くするほど、各ノズルまでの圧力損失の差が大きくなる。 The more narrow the main pipe 21 as desired when installed in settling basin, the difference in pressure loss to each nozzle is increased. その損失率は給水管1と母管21との接続位置から遠いノズルほど大きくなるため、各ノズルからの吐出量は、図6に示すように、給水管1と母管21との接続位置から遠いノズルほど減少する。 Since the loss rate increases as farther nozzle from the connection position between the water supply pipe 1 and the header pipe 21, the discharge amount from each nozzle, as shown in FIG. 6, from the connection position between the water supply pipe 1 and the header pipe 21 It decreases as far nozzle. 従って、このようなノズルヘッダーを用いると、沈砂池の底面に堆積する土砂を満遍なく効率的に流すことができないという問題がある。 Therefore, the use of such a nozzle header, it is impossible to flow evenly efficiently sediment deposited on the bottom surface of the sand basin.

本発明は、上記の事情に鑑みてなされたものであり、一つの液体供給源から供給される液体を複数の供給先に等量ずつ分配して供給することができる液体分配ヘッダーを提供することを目的とする。 The present invention has been made in view of the above circumstances, to provide a liquid dispensing headers that can be supplied by distributing a liquid to be supplied from one liquid supply source to a plurality of supply destinations equal amounts With the goal.

上記目的を達成するため、本発明に係る液体分配ヘッダーは、一つの液体供給源に接続される分岐管と、その分岐管の端部に接続される母管とからなり、母管はその内径が分岐管の内径よりも液体の流速および圧力損失を低減し得る程度に大きくされたものであり、母管の分岐管の端部との接続位置の両側にそれぞれ等数の孔が等間隔で設けられていることを特徴としている。 To achieve the above object, the liquid distribution header according to the present invention is composed of a branch pipe connected to a liquid supply source, a main pipe connected to an end of the branch pipe, the main pipe is an inner diameter There has been a large enough than the inner diameter of the branch pipe may reduce the flow rate and pressure loss of the liquid, each such number of holes on each side of the connection position between the ends of the branch pipes of the substrate tube at equal intervals It is characterized in that is provided.
請求項2に係る発明は、請求項1に係る発明の液体分配ヘッダーにおいて、分岐管の端部に接続される母管を互いに分離独立したものとし、それらの母管の長手方向中央位置に前記分岐管を接続し、かつ、各母管の分岐管との接続位置の両側にそれぞれ等数の孔を設けたことを特徴としている。 The invention according to claim 2 is the liquid distribution header of the invention according to claim 1, it is assumed that the header tube connected to an end of the branch pipe separated independently from each other, wherein the longitudinal center positions of the substrate tube connect the branch pipe, and is characterized in that a number of such respective holes on either side of the connection position of the branch pipes of each header pipe.

本発明によれば、母管の内径が分岐管の内径よりも大きいので、分岐管から母管に流れる液体の流速が減速され、かつ、圧力損失が低減され、また、分岐管の端部と母管との接続位置の両側にそれぞれ等数の孔が等間隔で取付けられているので、各孔までの圧力損失に大きな差が生じないため、各孔からの液体の吐出量はほぼ等しくなる。 According to the present invention, since the inner diameter of the substrate tube is greater than the inner diameter of the branch pipe, the flow rate of the liquid flowing in the main pipe is decelerated from the branch pipe, and the pressure loss is reduced, also, the end portion of the branch pipe since each such number of holes on each side of the connection position of the substrate tube is attached at equal intervals, because a large difference in pressure loss to each hole does not occur, the discharge amount of the liquid from each hole is substantially equal .

分岐管の両端に接続される母管を互いに分離独立したものとし、それらの母管の長手方向中央位置に前記分岐管を接続し、かつ、各母管の分岐管との接続位置の両側にそれぞれ等数の孔を設けた場合は、各母管を共通の1直線上に整列させることも、分岐管の各先端の軸線周りの角度を任意に変えることもできるから、液体供給先の状況に応じて、二つの母管の向きを変えることができる。 The mother pipe connected to both ends of the branch pipe and that separate and independent from each other, said connecting branch pipes to the longitudinal center positions of the substrate tube, and, on either side of the connection position of the branch pipes of each main pipe If provided with such number of holes respectively, also aligning the respective substrate tube in one common straight line, because it is also possible to vary the angle about the axis of the tip of the branch pipes optionally liquid supply destination status depending on the, it is possible to change the direction of two of the mother tube.

続いて、本発明の実施の形態について図面を参照しながら説明する。 Next, with reference to the accompanying drawings, embodiments of the present invention.
以下には、本発明に係る液体分配ヘッダーをノズルヘッダーに適用した場合について説明する。 Hereinafter will be described a case where the liquid distribution header according to the present invention is applied to the nozzle headers.
図1において、2Aは本発明の1実施の形態に係るノズルヘッダーであり、母管21と分岐管23とからなっている。 In Figure 1, 2A is a nozzle header according to one embodiment of the present invention, consists mother pipe 21 branch pipe 23. 分岐管23は、その長手方向中間部に、液体供給源、例えば、給水管1に接続するための接続部23aを有する。 Branch pipe 23 has its longitudinal middle portion, the liquid supply source, for example, the connection portions 23a for connection to the water supply pipe 1. 接続部23aの先端には、給水管1の末端に設けられているフランジ1fと重ね合わせてボルトナットなどの固着具により固着されるフランジ23fが設けられている。 The distal end of the connecting portion 23a, a flange 23f is affixed is provided with fasteners, such as caused by a bolt nut overlapping a flange 1f provided at the end of the water supply pipe 1. 分岐管23の端部は母管21に、離れた位置において、好ましくは、母管21の端部から母管に接続されるノズルの数に応じて適切な所定の位置に接続されている。 The end main pipe 21 of the branch pipe 23, at a position away, preferably connected to a suitable place in accordance with the number of nozzles connected to the header pipe from the end of the substrate tube 21. 図1に例示されたノズルヘッダーは、8個のノズルが取付けられた例であり、この場合は、分岐管23の端部は母管21の端部から母管の長さの四分の一の位置に接続されている。 Nozzle headers illustrated in Figure 1 is an example attached eight nozzles, in this case, end quarter of the length of the substrate tube from the end of the main pipe 21 of the branch pipe 23 It is connected to the position.

母管21に取付けられたノズル22は、図2に例示するように、円管の先端を圧縮して、所定の断面積を有する長円形の噴射口を備えたものであり、母管21の分岐管23の端部との接続位置21a,21bの両側に等数(図1の例では、2個ずつ)となるように、かつ、各ノズルの間隔が等しくなるように、取付けられている。 Nozzle 22 attached to the main pipe 21, as illustrated in FIG. 2, to compress the tip end of the circular tube, which was equipped with oval jets having a predetermined cross-sectional area, of the substrate tube 21 connection position 21a of the end portion of the branch pipe 23 (in the example of FIG. 1, two by two) equal number on both sides of 21b so that, and, as the interval of each nozzle is equal attached . 技術常識であるので記載するまでもないが、母管21のノズル22が取付けられる位置には、ノズルを取り付ける孔(図示省略)が設けられている。 Without even described since it is technical common sense, a position where the nozzle 22 of the substrate tube 21 is mounted, holes for attaching the nozzle (not shown) is provided. そして、その孔に図2に示すようなノズルの雄ねじ部をねじ込むことにより取り付けられ、母管21の中空部とその孔に取付けられるノズル22の噴射口は、その孔を介して連通している。 Then, attached by screwing the male screw portion of the nozzle shown in FIG. 2 to the hole injection port of the nozzle 22 mounted with its hole hollow portion of the substrate tube 21 is communicated through the hole . また、いずれのノズル22も同じ口径を有し、調整機能を有しないものである。 Further, any of the nozzles 22 have the same diameter, but has no adjustment function. 母管21の両端部は、そのフランジ21fに閉そく板24を固着して、密閉されている。 Both end portions of the mother tube 21 is fixed to the closing plate 24 to the flange 21f, it is sealed.

そして、分岐管23の内径は給水管1の内径と等しいが、母管21の内径は分岐管23の内径よりも若干大きい。 Then, the inner diameter of the branch pipe 23 is equal to the inner diameter of the water supply pipe 1, the inner diameter of the substrate tube 21 is slightly larger than the inner diameter of the branch pipe 23. 母管21の内径の大きさは、ノズル22の噴射口の断面積を考慮に入れて、分岐管23から母管21に流入する水の流速が下がり、圧力損失が軽減されて、ノズルの吐出圧力と吐出量が各ノズル間で大きな差を生じない程度に設定される。 The inner diameter of the substrate tube 21, taking into account the cross-sectional area of ​​the injection port of the nozzle 22, the flow rate of water flowing into the main pipe 21 is lowered from the branch pipe 23, pressure loss is reduced, the discharge nozzle It is set so that the pressure and discharge amount does not produce a large difference between the nozzles.

一例を説明すれば、給水管1から水圧3kg/cm 2の水が供給される分岐管23の内径が約100mmで、断面積が約820mm 2のノズルを500mm間隔で8個取付けた母管21の場合は、その内径を約125mmに設定すればよい。 To describe one example, an inner diameter of about 100mm of the branch pipe 23 the water of the water supply pipe 1 from water pressure 3 kg / cm 2 is supplied, the substrate tube cross section mounted eight at 500mm intervals of about 820 mm 2 nozzle 21 for, it is sufficient to set the inner diameter of about 125 mm.
すなわち、母管21の内径は、分岐管23内の流速、ノズルの口径(断面積)及びノズル取付数などにより、適宜設定される。 That is, the inner diameter of the substrate tube 21, the flow rate in the branch pipe 23, the diameter (sectional area) of the nozzle and the like nozzle mounting number is appropriately set. 各ノズルの吐出量は、ノズル間距離により母管21と分岐管23の両端部との接続位置21a,21bから遠いものほど若干少なくなる。 Discharge amount of each nozzle, the connection position 21a of the two ends of the main pipe 21 and branch pipe 23 by the distance between nozzles, slightly smaller as the furthest from 21b.

上記のように、長手方向中間部において給水管1に接続される分岐管23の両端部を母管21に離れた位置において接続し、母管の内径を分岐管の内径よりも流速及び圧力損失を低減し得る程度に大きくし、母管の分岐管の両端との接続位置の両側にそれぞれ等数の所定の断面積を有するノズル22を等間隔に取付けると、各ノズル22での圧力がほぼ等しくなるため、図3に示すように、各ノズル22からの吐出量の差が少なくなる。 As described above, longitudinal in the direction intermediate portion of the both end portions of the branch pipe 23 connected to the water supply pipe 1 connected at a distance to the main pipe 21, flow velocity and pressure loss than the inner diameter of the inner diameter of the substrate tube branch pipe increased to the extent that can reduce, when mounting the nozzle 22 having a predetermined cross-sectional area of ​​the number of such on either side of the connection position between the ends of the branch pipes of the substrate tube at equal intervals, the pressure at each nozzle 22 is substantially since equal, as shown in FIG. 3, the difference in discharge amount from each nozzle 22 is reduced.

従って、このようなノズルヘッダーを沈砂池の両側の側壁に近い位置に設置し、ノズルからその沈砂池の底面に向けて水を噴射させるときは、その底面に満遍なく噴射することができるので、沈砂池の底面に堆積した土砂を満遍なく流すことができる。 Therefore, such a nozzle header installed at a position close to both side walls of the sand basin, when toward the bottom surface of the sand basin from nozzles jetting the water, it is possible to uniformly injected to the bottom surface, sand it can flow sediment deposited on the bottom of the pond evenly.

図4は、本発明の他の実施の形態に係るノズルヘッダー2Bを示す。 Figure 4 shows a nozzle header 2B according to another embodiment of the present invention. このノズルヘッダー2Bは、分岐管23の各端部に対してそれぞれ独立した母管21L,21Rを接続したものである。 The nozzle header 2B is obtained by connecting independent header pipe 21L, the 21R to each end of the branch pipe 23. 各母管21L,21Rの分岐管23との接続部21a,21bの両側に等数の、図示の例では2個ずつの、ノズル22が等間隔をおいて取付けられている。 Each main pipe 21L, the connection portions 21a of the branch pipe 23 of 21R, etc. The number on either side of 21b, the two by two in the illustrated embodiment, the nozzle 22 is mounted at equal intervals.

この実施の形態のように、分離独立した母管を用いる場合は、各母管を共通の1直線上に整列させることも、分岐管23の各先端の軸線周りの角度を任意に変えることもできる。 As in this embodiment, the case of using a separate and independent mother pipe can also be aligned each main pipe to one common straight line, also changing the angle about the axis of the distal end of the branch pipe 23 as desired it can. すなわち、水噴射対象面の状況に応じて二つの母管21L,21Rの向きを変えることができる。 That is, it is possible to change the two main pipe 21L, 21R orientation according to the condition of the water injection target surface. 傾斜方向が一様の一つの面、傾斜方向が異なる二つ面などに水を噴射する場合などに使用するのに適している。 One face of the inclined direction uniform, the inclination direction is suitable for use, such as when injecting water into such two different surface.

上記実施の形態においては、ノズル22にはいずれも同じ口径を有し、口径調整機能を有しないものを用いたが、口径調整機能を有するノズルを用いることもできる。 In the above-described embodiment, has the same diameter both in the nozzle 22, was used having no aperture adjusting function, it is also possible to use a nozzle having a diameter adjusting function. その場合は、ノズルの取付誤差等による噴射量のアンバランスを微調整できるという利点がある。 In that case, there is an advantage that the unbalance of the injection quantity due to the mounting error of the nozzle can be finely adjusted.

ノズル22の噴射口の形状は、図2のものに限定されるものではない。 The shape of the injection port of the nozzle 22 is not limited to that of FIG. また、液体分配ヘッダー2A,2Bは、母管の分岐管の端部との接続位置の両側にそれぞれ等数の孔が設けてある状態で供給され、液体分配ヘッダー2A,2Bの購入者が使用目的に応じたノズルをその孔に取付けることもできる。 Also, liquid distribution headers 2A, 2B is supplied in a state such as the number respective holes on either side of the connection position is provided between the end portion of the branch pipe of the header pipe, the liquid distribution headers 2A, 2B buyers using the nozzle according to the purpose can be attached to the hole.
