Description
【０００１】[0001]
本考案は、一般にビクトリック型と呼ばれる管継手に関する。 The present invention relates to a pipe joint generally called a victor type.
【０００２】[0002]
図４〜図７は、従来のビクトリック型管継手の一例を示す。上下対称で半環状 に形成された一対の鋳物製ハウジング１Ａ及びハウジング１Ｂを有し、両ハウジ ング１Ａ、１Ｂの内周縁に沿って両側に爪部１ａ、１ｂが形成されている。接続 される２つの管２Ａ、２Ｂの各管端部近傍には環状溝（グルーブ）２ａ、２ｂが 設けてあり、両管２Ａ、２Ｂの環状溝２ａ、２ｂに跨ってハウジング１Ａ、１Ｂ の両側の爪部１ａ、１ｂを係合させる。また、図４及び図５のように、ハウジン グ１Ａ、１Ｂの内周面に沿ってゴム製の弾性パッキン５が装着され、この弾性パ ッキン５を管２Ａ、２Ｂの各管端部に跨ってこれらの外周面に密着して取り付け る。また、ハウジング１Ａ、１Ｂの各両端に設けられたフランジ同士をボルト３ 及びナット４で締結することにより、２つの管２Ａ、２Ｂが接続される。この場 合、弾性パッキン５にはこの外側から両ハウジング１Ａ、１Ｂが密接すると共に 、２つの管２Ａ、２Ｂに跨って各管端部の外周面に弾性力で密着し、シール部材 として２つの管２Ａ、２Ｂの間の気密性又は液密性を確保する。 また、図６に示すように、ハウジング１Ａ（１Ｂ）の爪部１ａ（１ｂ）の幅寸 法は、管２Ａ、２Ｂの環状溝２ａ、２ｂの溝幅寸法よりも狭く、両者間には幅寸 法差による間隙Ｇが設けられている。この間隙Ｇによる遊びによって組立時の作 業性を向上させている。また、遊びを設けることによって、配管された管２Ａ、 ２Ｂの軸方向への伸縮、芯ずれ及び屈曲等を吸収できる利点がある。 しかし、寸法的な遊びとして必要以上に大きな間隙Ｇを設けると次のような不 具合がある。配管後の使用中にあって、管内の流体圧による負荷変動とか、ある いは何らかの外力が作用すると、両方の管２Ａ、２Ｂが管軸線方向に相対に移動 したり、回転力が作用して芯ずれや撓み、そして曲がりなどの変形が発生する。 そのため、所要のシール性を確保することができない。こうした不具合に対処す るため、配管後の両管の要所を吊り具で補強支持する必要が生じ、作業手間や部 品の増加により設備コストの面で不利である。 この点に関し、図７のように間隙Ｇによる遊びを殆ど設けない構造も知られて いる。即ち、管２Ａ（２Ｂ）の環状溝２ａ（２ｂ）の溝幅を狭くし、ハウジング １Ａ（１Ｂ）の爪部１ａ（１ｂ）との間に形成される間隙Ｇをゼロもしくは極小 とすれば、管２Ａ、２Ｂの芯ずれや曲がりなどの発生をある程度抑えることがで きる。 4 to 7 show an example of a conventional Victorian pipe joint. It has a pair of casting housings 1A and 1B that are vertically symmetrical and formed in a semi-annular shape, and claw portions 1a and 1b are formed on both sides along the inner peripheral edges of both housings 1A and 1B. Two pipes 2A, 2B to be connected are provided with annular grooves (grooves) 2a, 2b in the vicinity of the respective pipe ends, and both sides of the housings 1A, 1B straddle the annular grooves 2a, 2b of the two pipes 2A, 2B. The claw portions 1a and 1b of 1 are engaged. Further, as shown in FIGS. 4 and 5, elastic packings 5 made of rubber are attached along the inner peripheral surfaces of the housings 1A and 1B, and the elastic packings 5 are extended over the respective pipe ends of the pipes 2A and 2B. And attach them closely to these outer peripheral surfaces. Further, the two pipes 2A and 2B are connected by fastening the flanges provided at both ends of the housings 1A and 1B together with the bolt 3 and the nut 4. In this case, both the housings 1A and 1B come into close contact with the elastic packing 5 from the outside, and the elastic packing 5 also comes into close contact with the outer peripheral surface of each pipe end portion over the two pipes 2A and 2B by an elastic force, so that two seal members are provided. The airtightness or the liquidtightness between the tubes 2A and 2B is ensured. Further, as shown in FIG. 6, the width dimension of the claw portion 1a (1b) of the housing 1A (1B) is narrower than the groove width dimension of the annular grooves 2a and 2b of the tubes 2A and 2B, and the width between them is wide. A gap G is provided due to the size difference. The play due to the gap G improves workability during assembly. Further, by providing the play, there is an advantage that the expansion and contraction of the pipes 2A and 2B in the axial direction, the misalignment, the bending, and the like can be absorbed. However, if a gap G larger than necessary is provided as dimensional play, the following problems occur. During use after piping, if load fluctuations due to fluid pressure in the pipes or some external force acts, both pipes 2A and 2B move relative to each other in the pipe axis direction, and rotational force acts. Deformation such as misalignment, bending, and bending occurs. Therefore, the required sealing property cannot be secured. In order to deal with such a problem, it is necessary to reinforce and support the important points of both pipes after the piping with a hanger, which is disadvantageous in terms of equipment cost due to increase in labor and parts. In this regard, there is known a structure in which the play due to the gap G is hardly provided as shown in FIG. That is, if the groove width of the annular groove 2a (2b) of the tube 2A (2B) is narrowed and the gap G formed between the annular groove 2a (2b) and the claw portion 1a (1b) of the housing 1A (1B) is set to zero or minimum, The occurrence of misalignment or bending of the tubes 2A and 2B can be suppressed to some extent.
【０００３】[0003]
しかしながら、図７の構造のように間隙Ｇによるを設けない場合、管継手と管 との間の相対的な変形を防止できる利点がある反面、遊びがないために作業性が 著しく低下するといった問題がある。加えて、遊びを設けないということは、一 対のハウジング１Ａ、１Ｂにある程度の精度誤差を免れ得ないため、双方の接合 面を一致させることが極めて困難である。この場合、無理に接合させるとその接 合面から弾性パッキン５が外部に迫り出し、体裁を悪くすることは勿論、パッキ ン自体のシール性を低下させる原因ともなる。 このように、図６の間隙Ｇによる遊びを設けた場合、図７の設けない場合のい ずれの構造にもそれぞれの利点があり、共に解決すべき問題を残している。 従って、本考案は、以上のような種々の問題点の解決を図り、同時に改良を加 えて接続後の曲げに対する剛性も高められる管継手を提供することを目的として いる。 However, when the gap G is not provided as in the structure of FIG. 7, there is an advantage that relative deformation between the pipe joint and the pipe can be prevented, but there is no play, so the workability is significantly reduced. There is. In addition, the absence of play cannot avoid some precision error in the pair of housings 1A and 1B, so that it is extremely difficult to match the joint surfaces of the two. In this case, if they are forcibly joined, the elastic packing 5 squeezes out from the joining surface to the outside, which not only deteriorates the appearance but also deteriorates the sealing property of the packing itself. As described above, in the case where the play by the gap G in FIG. 6 is provided and in the case where the play is not provided in FIG. 7, both structures have their respective advantages, and both of them have a problem to be solved. Therefore, an object of the present invention is to solve the above-mentioned various problems, and at the same time, to provide a pipe joint which is improved and also improved in rigidity against bending after connection.

本考案による管継手は、半環状のハウジングの一対が輪環形に結合され、ハウ ジングの軸方向の両側で半周縁に沿って係合爪が設けられ、両側の係合爪を２つ の接続管の各端部に設けられた環状溝に跨って係合させるにあたって、係合爪に 複数の堅締用突起部が放射状かつ外側に突出して設けられ、係合した係合爪と環 状溝との間隙に堅締用突起部を係入させるようになっている。 堅締用突起部としては、組立性を考慮して係合爪の周端部を除くことが好まし い。また、堅締用突起部の環状溝に臨む側にテーパ部を設けることによって、環 状溝との間に生じた間隙Ｇへの初期の係入が容易で、組立性が高まる。 In the pipe joint according to the present invention, a pair of semi-annular housings are coupled to each other in a ring shape, engaging claws are provided along the semi-periphery on both sides in the axial direction of the housing, and two engaging claws on both sides are connected. When engaging over the annular grooves provided at each end of the pipe, the engaging claws are provided with a plurality of fastening projections radially and projecting outward, and the engaging claws and the annular grooves engaged with each other. The protrusion for tightening is engaged in the gap between and. It is preferable to remove the peripheral end portion of the engaging claw as the tightening protrusion in consideration of the assemblability. Further, by providing the taper portion on the side of the fastening projection which faces the annular groove, the initial engagement into the gap G formed between the fastening groove and the annular groove is easy and the assemblability is enhanced.

配管に際し、ボルトとナットによる本締めを開始すると、ハウジングの係合爪 が係合する管の環状溝では、係合爪と環状溝との間に生じた間隙に堅締用突起部 が食い込むようにして係入する。これによって、係合爪と環状溝との間の遊びが ほとんど無くなり、管同士が強固に接続され、軸方向への伸縮や曲がりの発生を 抑えられる。 When starting the final tightening with bolts and nuts during piping, the tightening protrusions will bite into the gap between the engaging claw and the annular groove in the annular groove of the pipe with which the engaging claw of the housing engages. And enter. As a result, there is almost no play between the engaging claw and the annular groove, the tubes are firmly connected, and expansion and contraction in the axial direction and bending are suppressed.

以下、本考案による管継手の実施例を図面に基づいて説明する。 図１〜図３に示すように、管継手１０は半環状一対で同形状の鋳物製ハウジン グ１１を上下に抱き合わせて結合される。ハウジング１１の内周面には、これに 沿って密着できる大きさの環状でゴム材質による弾性パッキン２０が装着される 。 上下各ハウジング１１は両端から突出した左右の結合フランジ１２、１２を有し 、それぞれに設けた締結孔１３にボルト１５を挿通させてナット１６で締め込み 、上下のハウジング１１、１１が共締めにより結合される。また、ハウジング１ １の軸方向の両側にはそれぞれ半環状周縁に沿って係合爪１４、１４が設けられ 、この両側の係合爪１４、１４を、図２のように、接続される両側２本の管３０ 、３１に跨って両管端部の外周の環状溝（グルーブ）３０ａ、３１ａに係合させ るようになっている。図６で説明されたように、係合爪１４及び環状溝３０ａ（ ３１ａ）の幅寸法は両部材間に間隙Ｇが生じるよう設定されている。両管３０、 ３１の環状溝３０ａ、３１ａは専用工具や機器で現場加工される。 An embodiment of a pipe joint according to the present invention will be described below with reference to the drawings. As shown in FIG. 1 to FIG. 3, the pipe joint 10 is a pair of semi-annular pipes, and casting housings 11 of the same shape are vertically joined together and joined. On the inner peripheral surface of the housing 11, an elastic packing 20 made of a rubber material and having an annular shape having a size capable of closely contacting the inner peripheral surface of the housing 11 is mounted. Each of the upper and lower housings 11 has left and right coupling flanges 12 and 12 protruding from both ends, and bolts 15 are inserted into respective fastening holes 13 and tightened with nuts 16, so that the upper and lower housings 11 and 11 are fastened together. Be combined. In addition, engaging claws 14 and 14 are provided on both sides in the axial direction of the housing 11 along the semi-circular peripheral edge, and the engaging claws 14 and 14 on both sides are connected to both sides as shown in FIG. The two pipes 30 and 31 are arranged so as to be engaged with annular grooves (grooves) 30a and 31a on the outer circumferences of both pipe ends. As described with reference to FIG. 6, the width dimension of the engaging claw 14 and the annular groove 30a (31a) is set so that a gap G is formed between both members. The annular grooves 30a and 31a of both pipes 30 and 31 are machined on-site with special tools and equipment.
【０００７】 ここで、ハウジング１１の軸方向の一方側と他方側の各側面には複数の凸状リ ブ（堅締用突起部）１７が一体成形されている。実施例では、１つのハウジング １１について一方側と他方側に３個づつ、両側面で計６個のリブ１７が放射状に 設けられている。リブ１７が設けられる位置としては、左右の結合フランジ１２ 、１２の下面内角（周端部）１２ａ、１２ａもしくはこの近傍を避けて、ハウジ ング１１の直径方向の軸心から実施例では角度３０°で左右に振り分けた２個所 と、角度９０°の上位置又は下位置の１個所の計３個である。Here, a plurality of convex ribs (tightening projections) 17 are integrally formed on each side surface of the housing 11 on one side and the other side in the axial direction. In the embodiment, one housing 11 is provided with three ribs 17 on one side and another on the other side, and a total of six ribs 17 are radially provided on both side surfaces. As the position where the rib 17 is provided, avoid the inner angle (peripheral end) 12a, 12a of the lower surface of the left and right coupling flanges 12, 12 or the vicinity thereof, and an angle of 30 ° in the embodiment from the diametrical axis of the housing 11. There are a total of 3 places, 2 places that are distributed to the left and right, and 1 place that is located at an upper or lower angle of 90 °.
【０００８】 結合フランジ１２の下面内角１２ａにリブ１７の設置を避ける理由は、管３０ （３１）の環状溝３０ａ（３１ａ）に係合させて組み立てる際、結合フランジ１ ２の下面内角１２ａが最初に環状溝３０ａ（３１ａ）に係入し始めることことか ら、この位置に突出したリブ１７があったのでは、組立ての支障となるからであ る。また、図２で明らかなように、係合爪１４が係合して生じた環状溝３０ａ（ ３１ａ）の間隙Ｇへの係入都合を考慮すれば、リブ１７はその長手方向が軸心を 通る直径に垂直に、つまり左右の結合フランジ１２、１２の下面を通る図の左右 方向の直径に対して垂直に設けられている。以上のような規制を除けば、組立性 容易を踏まえてリブ１７の設置個数、ならびに下面内角１２ａを回避した左右振 り分けの角度は３０°に限定されるものではない。また、図示のように、リブ１ ７の環状溝３０ａ（３１ａ）に臨む側にテーパ部１７ａを設けることが好ましい 。テーパ部１７を設けることによって、間隙Ｇへの初期の係入が容易で組立性を 高めることができる。The reason for avoiding the installation of the rib 17 on the lower surface inner angle 12a of the coupling flange 12 is that the lower surface inner angle 12a of the coupling flange 12 is initially set when engaging with the annular groove 30a (31a) of the pipe 30 (31) to assemble. This is because the rib 17 protruding at this position is a hindrance to the assembly because the rib 17 starts to be engaged with the annular groove 30a (31a). Further, as is apparent from FIG. 2, considering the convenience of engaging the annular groove 30a (31a) with the engagement claw 14 into the gap G, the longitudinal direction of the rib 17 has an axial center. It is provided perpendicular to the passing diameter, that is, perpendicular to the diameter in the left-right direction in the drawing that passes through the lower surfaces of the left and right coupling flanges 12, 12. Except for the above restrictions, the number of ribs 17 installed and the left-right distribution angle that avoids the lower surface inner angle 12a are not limited to 30 ° in view of easy assembly. Further, as shown in the drawing, it is preferable to provide a tapered portion 17a on the side of the rib 17 facing the annular groove 30a (31a). By providing the taper portion 17, the initial engagement in the gap G is easy and the assembling property can be improved.
【０００９】 次に、実施例の管継手１０による管３０、３１の接続態様例及び作用を説明す る。 配管時の組立手順の一例として、図２に示すように、接続される２本の管３０ 、３１の軸線を揃えて互いの管端部を対向させ、弾性パッキン２０の両側のリッ プシール部２１、２１を双方の管３０、３１に跨ってこれらの管端部の外周面に 装着する。この弾性パッキン２０を内側に抱き込むようにして一対のハウジング １１、１１を接合させ、両ハウジング双方の結合フランジ１２、１２同士をボル ト１５とナット１６で仮締めする。但し、一対のハウジング１１、１１をボルト １５とナット１６とで仮組し、予め両ハウジング１１、１１の内周に沿わせて弾 性パッキン３０を装着しておいて、仮組状態の管継手１０に両側から管３０、３ １の管端部を差し入れる方法でも可能である。Next, an example and a function of connecting the pipes 30 and 31 by the pipe joint 10 of the embodiment will be described. As an example of an assembly procedure at the time of piping, as shown in FIG. 2, the axial lines of the two pipes 30 and 31 to be connected are aligned so that their pipe ends face each other, and the lip seal portions 21 on both sides of the elastic packing 20 are arranged. , 21 are mounted on the outer peripheral surfaces of the end portions of both pipes 30 and 31. A pair of housings 11 and 11 are joined so as to embrace the elastic packing 20 inside, and joint flanges 12 and 12 of both housings are temporarily tightened with a bolt 15 and a nut 16. However, the pair of housings 11, 11 are temporarily assembled with the bolts 15 and the nuts 16, and the elastic packing 30 is attached along the inner peripheries of both the housings 11, 11 in advance, and the pipe joint in the temporarily assembled state. It is also possible to insert the tube ends of the tubes 30 and 31 into the tube 10 from both sides.
【００１０】 これより、ボルト１５とナット１６による本締めが行われる。本締めによって 上下一対のハウジング１１、１１では左右の係合爪１４、１４が両管３０、３１ の環状溝３０ａ、３１ａに係合する。係合に際して、係合爪１４では下面内角１ ２ａが始めに環状溝３０ａ（３１ａ）に係入する。係合爪１４の係合によって環 状溝３０ａ（３１ａ）に生じた間隙Ｇに複数のリブ１７も係入する。間隙Ｇへの リブ１７の係入によって係合爪１４の環状溝３０ａ（３１ａ）における係合力が 高まって堅締し、即ち遊びが無くなって管２０、２１の接続トルクが増大して強 化される。リブ１７の間隙Ｇへの係入の際、リブ１７にテーパ部１７ａを設けて いることで、組立が容易になる他、傷が付きにくい利点がある。As a result, the final tightening with the bolt 15 and the nut 16 is performed. By the final tightening, the left and right engaging claws 14, 14 of the pair of upper and lower housings 11, 11 engage with the annular grooves 30a, 31a of the tubes 30, 31, respectively. At the time of engagement, the lower surface inner angle 12a of the engagement claw 14 first engages with the annular groove 30a (31a). The plurality of ribs 17 are also engaged in the gap G formed in the annular groove 30a (31a) by the engagement of the engagement claws 14. By engaging the rib 17 into the gap G, the engaging force in the annular groove 30a (31a) of the engaging claw 14 is increased and tightened, that is, there is no play and the connection torque of the pipes 20 and 21 is increased and strengthened. It When the rib 17 is engaged in the gap G, the rib 17 is provided with the tapered portion 17a, which facilitates the assembling and has an advantage that it is not easily scratched.
【００１１】 一対のハウジング１１、１１を強固に結合することによって、弾性パッキン２ ０がハウジング１１の内周面に密着し、両側のリップシール部２１、２１が管３ ０、３１の管端部外周面に密着する。弾性パッキン２０の密着によって両側の管 ３０、３１は所要の液密又は気密を確保して接続される。By firmly coupling the pair of housings 11 and 11, the elastic packing 20 is brought into close contact with the inner peripheral surface of the housing 11, and the lip seal portions 21 and 21 on both sides are pipe end portions of the pipes 30 and 31. Stick to the outer peripheral surface. Due to the close contact of the elastic packing 20, the pipes 30 and 31 on both sides are connected while ensuring a required liquid tightness or air tightness.

以上説明したように、本考案による管継手は、ビクトリック型に好敵であり、 ハウジングの係合爪に複数のリブ（堅締用突起部）を外側へ突出させて設けるこ とで、本締め後は、接続される管の環状溝（グルーブ）に係合爪が係合した際、 リブが係合爪と環状溝との間の間隙に食い込んで遊びがほぼ皆無となり、曲げ荷 重を抑制して管同士の接続が強固となって軸線方向への伸縮や曲がりの発生を抑 えるのに有効である。 As described above, the pipe joint according to the present invention is suitable for the victoric type, and the engaging claw of the housing is provided with a plurality of ribs (tightening projections) protruding outward so that After tightening, when the engaging claw is engaged with the annular groove of the pipe to be connected, the rib bites into the gap between the engaging claw and the annular groove, and there is almost no play, and the bending load is reduced. It is effective in suppressing the expansion and bending in the axial direction by strengthening the connection between the pipes.
