Description
本発明は、管端を接続するための管継手に関する。 The present invention relates to a pipe joint for connecting pipe ends.
管端を接続する管継手としては、ハウジング形管継手が知られている。例えば、図１２に示すハウジング形管継手は、一対の円弧状継手セグメント１，２と、それぞれ周方向溝３を有する２つの管４，５の端部を収容するために各円弧状継手セグメントに形成された空間６と、当該空間６内に２つの管４，５の端部をシールするように設けられる弾性リング７と、前記空間６の両側で半径方向内方に延びて２つの管４，５の各周方向溝３に係合する２つの締付部８，９と、一対の継手セグメント１，２を互いに結合するための取付手段１０と、から形成されている。 A housing-type pipe joint is known as a pipe joint for connecting pipe ends. For example, the housing-type pipe joint shown in FIG. 12 has a pair of arc-shaped joint segments 1 and 2 and each arc-shaped joint segment to accommodate the ends of two pipes 4 and 5 each having a circumferential groove 3. The formed space 6, the elastic ring 7 provided to seal the ends of the two tubes 4 and 5 in the space 6, and the two tubes 4 extending radially inward on both sides of the space 6 , 5 and two fastening portions 8 and 9 engaged with the circumferential grooves 3 and attachment means 10 for connecting the pair of joint segments 1 and 2 to each other.
このようなハウジング形管継手では、一対の円弧状継手セグメント１，２の空間６，６に配置される弾性リング７が、２つの管４，５の端部外周面に圧接することによって、２つの管４，５の端部をシールすることができる。また、各継手セグメント１，２に設けられた締付部８，９を２つの管４，５の端部に設けられた周方向溝３の底部に圧接することによって、２つの管４，５を円弧状継手セグメント１，２に固定することができる。 In such a housing-type pipe joint, the elastic ring 7 disposed in the spaces 6 and 6 of the pair of arc-shaped joint segments 1 and 2 presses the outer peripheral surface of the ends of the two pipes 4 and 5, thereby The ends of the two tubes 4 and 5 can be sealed. Further, the two pipes 4, 5 are brought into pressure contact with the bottoms of the circumferential grooves 3 provided at the ends of the two pipes 4, 5 by tightening parts 8, 9 provided in the joint segments 1, 2. Can be fixed to the arc-shaped joint segments 1 and 2.
しかしながら、前記したハウジング形管継手は、一対の円弧状継手セグメント１，２の形状が固定であるために、管が変形等して管の断面形状が真円から大きく逸れてしまっている場合に、各円弧状セグメントを管上に沿うように取り付けることが難しく、結果的に漏洩防止の効果が十分に得られないことがあった。 However, the above-described housing-type pipe joint has a pair of arc-shaped joint segments 1 and 2 having a fixed shape, so that when the pipe is deformed or the like, the cross-sectional shape of the pipe has greatly deviated from a perfect circle. It is difficult to attach each arc segment along the pipe, and as a result, the effect of preventing leakage may not be obtained sufficiently.
本発明は、以上のような問題点に着目し、これを有効に解決すべく創案されたものである。本発明の目的は、管が変形等して管の断面形状が真円から大きく逸れてしまっている場合であっても、漏洩防止作用を確実に発揮することが可能な管継手を提供することにある。 The present invention has been devised to pay attention to the above problems and to effectively solve them. An object of the present invention is to provide a pipe joint capable of reliably exhibiting a leakage preventing action even when the pipe is deformed or the like and the cross-sectional shape of the pipe is greatly deviated from a perfect circle. It is in.
本発明は、一側管体と他側管体とを接続する管継手において、一側管体の外面から他側管体の外面に至るように配置される側面視Ｃ字状のゴムリングと、前記ゴムリングの一側端部の外側面上に載置される、一側ハウジングと、前記ゴムリングの他側端部の外側面上に載置される、他側ハウジングと、前記一側ハウジングの他側端部と前記他側ハウジングの一側端部とを結合する端部結合部材と、前記一側ハウジングの一側端部から前記他側ハウジングの他側端部に至るまでの前記ゴムリングの外側面上に載置される、複数の中間ハウジングと、前記一側ハウジングの一側端部、各中間ハウジングの各端部、前記他側ハウジングの他側端部のうちの隣接する２つの端部を間隙調整可能に結合する間隙調整結合部材と、を備えたことを特徴とする管継手である。 The present invention relates to a pipe joint for connecting a one-side tube body and another-side tube body, and a rubber ring having a C-shaped side view disposed so as to extend from the outer surface of the one-side tube body to the outer surface of the other-side tube body. The one side housing placed on the outer surface of the one end of the rubber ring, the other housing placed on the outer surface of the other end of the rubber ring, and the one side An end coupling member that couples the other side end of the housing and the one side end of the other side housing; and from the one side end of the one side housing to the other side end of the other side housing A plurality of intermediate housings mounted on the outer surface of the rubber ring, adjacent to one side end of the one side housing, each end of each intermediate housing, and the other side end of the other side housing A gap adjusting coupling member that couples the two ends so that the gap can be adjusted. It is a pipe joint.
本発明によれば、管継手のハウジングを構成する部材が、一側ハウジングと、他側ハウジングと、複数の中間ハウジングと、に分離されて構成されているため、管が変形等して管の断面形状が真円から大きく逸れてしまっている場合であっても、ハウジングの各々を管上に沿うように取り付けることが可能であり、結果として漏洩防止作用を確実に発揮することができる。 According to the present invention, the members constituting the housing of the pipe joint are configured to be separated into the one side housing, the other side housing, and the plurality of intermediate housings. Even when the cross-sectional shape is greatly deviated from the perfect circle, each of the housings can be attached along the pipe, and as a result, the leakage preventing action can be surely exhibited.
好ましくは、前記ゴムリングの一側端部には、一側フランジ部が設けられており、前記ゴムリングの他側端部には、他側フランジ部が設けられており、前記一側ハウジングの他側端部と前記他側ハウジングの一側端部とが端部結合部材によって結合される際に、前記一側フランジ部と前記他側フランジ部とは液密に密着するようになっている。この場合、漏洩防止作用をより確実に保証することができる。 Preferably, one side end of the rubber ring is provided with one side flange, and the other side end of the rubber ring is provided with another side flange. When the other side end and the one side end of the other side housing are coupled by the end coupling member, the one side flange and the other side flange are in close contact with each other. . In this case, the leakage preventing effect can be more reliably ensured.
また、好ましくは、前記ゴムリングは、内面側に凹部を有する断面を有している。この場合、当該凹部内に、一側管体と他側管体との接続部材（例えば締結ボルト）を収容することができる。 Preferably, the rubber ring has a cross section having a recess on the inner surface side. In this case, the connection member (for example, fastening bolt) of the one side tube body and the other side tube body can be accommodated in the concave portion.
また、好ましくは、前記ハウジングの各々は、前記ゴムリングの外側面上に載置される、側面視円弧状の載置面を有している。そのような載置面によって、管の断面形状が真円に近い場合に管上に沿った取り付けが実現される一方で、管が変形等して管の断面形状が真円から大きく逸れてしまっている場合であっても、ハウジングの各々が少なくとも４つに分離していることによって、やはり管上に沿うように取り付けることが可能である。 Preferably, each of the housings has a mounting surface that is mounted on the outer surface of the rubber ring and has an arc shape in a side view. With such a mounting surface, when the cross-sectional shape of the tube is close to a perfect circle, mounting along the tube is realized, but the tube is deformed and the cross-sectional shape of the tube is greatly deviated from the perfect circle. Even in such a case, each of the housings is separated into at least four, so that it can be mounted along the pipe.
また、好ましくは、前記ハウジングの各々は、前記ゴムリングの両方の側方面の少なくとも一部を覆う形状を有している。この場合、ハウジングの各々によってゴムリングを効果的に保護することができる。 Preferably, each of the housings has a shape covering at least a part of both side surfaces of the rubber ring. In this case, the rubber ring can be effectively protected by each of the housings.
また、好ましくは、前記一側ハウジングと前記他側ハウジングとは、鏡像対称な形状を有している。このような場合、それらハウジングの製造コストや組立作業の容易性において優れる。 Preferably, the one-side housing and the other-side housing have a mirror image symmetrical shape. In such a case, the manufacturing cost of these housings and the ease of assembly work are excellent.
また、好ましくは、前記複数の中間ハウジングは、互いに同一の形状を有している。このような場合、それらハウジングの製造コストや組立作業の容易性において優れる。この場合、前記一側ハウジングと前記他側ハウジングとを結合した時の側面視の円弧形状の長さが、前記中間ハウジング一つの側面視の円弧形状の長さと、略等しいことが更に好ましい。この場合、管が変形等して管の断面形状が真円から大きく逸れてしまっている場合に，管上に沿ったハウジングの各々の取り付けをバランスよく実現することができる。この場合、中間ハウジングの数が、１１や２３等（４ｎ＋３（ｎは自然数））であれば、バランスが極めて良好である。 Preferably, the plurality of intermediate housings have the same shape. In such a case, the manufacturing cost of these housings and the ease of assembly work are excellent. In this case, it is more preferable that the length of the circular arc shape in the side view when the one side housing and the other side housing are coupled is substantially equal to the length of the circular arc shape in the side view of the one intermediate housing. In this case, when the tube is deformed or the like, and the cross-sectional shape of the tube is greatly deviated from the perfect circle, the mounting of each housing along the tube can be realized in a balanced manner. In this case, if the number of intermediate housings is 11 or 23 (4n + 3 (n is a natural number)), the balance is extremely good.

図４は、図３のゴムリング１１への一側ハウジング２１及び他側ハウジング２２の取り付けを説明するための図であり、図５は、図３のゴムリング１１への中間ハウジング２３〜３４の取り付けを説明するための図である。図１、図４及び図５に示すように、本実施の形態の各ハウジング２１〜３４は、ゴムリング１１の外側面上に載置される載置面が同一曲率の側面視円弧状となっている。本実施の形態では、中央の主たる載置面のみならず、左右（図４及び図５における紙面前後）の側方載置面についても、側面視円弧状となっている。 4 is a view for explaining the attachment of the one-side housing 21 and the other-side housing 22 to the rubber ring 11 of FIG. 3, and FIG. 5 is a view of the intermediate housings 23 to 34 to the rubber ring 11 of FIG. It is a figure for demonstrating attachment. As shown in FIGS. 1, 4, and 5, each of the housings 21 to 34 according to the present embodiment has a mounting surface mounted on the outer surface of the rubber ring 11 in an arc shape with a same curvature. ing. In the present embodiment, not only the main main mounting surface but also the lateral mounting surfaces on the left and right sides (front and rear in FIG. 4 and FIG. 5) are arcuate in side view.
また、図１、図４及び図５に示すように、ハウジング２１〜３４の各々は、ゴムリング１１の両方の側方面の大部分を覆う形状を有している。また、本実施の形態では、一側ハウジング２１と他側ハウジング２２とは、鏡像対称な形状を有しており、複数の中間ハウジング２３〜３３は、互いに同一の形状を有している。さらに、本実施の形態では、図１に示すように、一側ハウジング２１と他側ハウジング２２とを結合した時の側面視の円弧形状の長さが、中間ハウジング２３〜３３の一つの側面視の円弧形状の長さと、略等しくなっている。 As shown in FIGS. 1, 4, and 5, each of the housings 21 to 34 has a shape that covers most of both side surfaces of the rubber ring 11. In the present embodiment, the one-side housing 21 and the other-side housing 22 have a mirror image symmetrical shape, and the plurality of intermediate housings 23 to 33 have the same shape. Further, in the present embodiment, as shown in FIG. 1, the length of the circular arc shape in a side view when the one-side housing 21 and the other-side housing 22 are coupled is equal to one side view of the intermediate housings 23 to 33. Is substantially equal to the length of the arc shape.
以上のような本実施の形態によれば、管継手１０のハウジングを構成する部材が、一側ハウジング２１と、他側ハウジング２２と、複数の中間ハウジング２３〜３３と、に分離されて構成されているため、管体５１、５２が変形等して管体５１、５２の断面形状が真円から大きく逸れてしまっている場合であっても、ハウジング２１〜３３の各々を管上に沿うように取り付けることが可能であり、結果として漏洩防止作用を確実に発揮することができる。具体的には、図１のように接続対象の管体５１及び５２の断面形状が真円に近い場合だけでなく、図６のように接続対象の管体５１及び５２の断面形状が真円から大きく逸れて扁平になっている場合においても、漏洩防止作用を確実に発揮することができる。 According to the present embodiment as described above, the members constituting the housing of the pipe joint 10 are configured to be separated into the one-side housing 21, the other-side housing 22, and the plurality of intermediate housings 23 to 33. Therefore, even if the pipe bodies 51 and 52 are deformed and the cross-sectional shape of the pipe bodies 51 and 52 is greatly deviated from the perfect circle, the housings 21 to 33 are arranged along the pipes. As a result, it is possible to reliably exhibit the leakage preventing action. Specifically, not only when the cross-sectional shapes of the connection target pipe bodies 51 and 52 are close to a perfect circle as shown in FIG. 1, but also the cross-sectional shape of the connection target pipe bodies 51 and 52 is a perfect circle as shown in FIG. Even in the case of flattened and greatly deviated from the above, the leakage preventing action can be surely exhibited.
また、本実施の形態によれば、ゴムリング１１の一側フランジ部１２と他側フランジ部１３とが液密に密着していることにより、漏洩防止作用をより確実に保証することができる。 Moreover, according to this Embodiment, since the one side flange part 12 and the other side flange part 13 of the rubber ring 11 are closely_contact | adhered liquid-tightly, a leak prevention effect | action can be ensured more reliably.
また、本実施の形態によれば、ゴムリング１１が内面側に凹部１４を有する断面を有していることにより、一側管体５１と他側管体５２との接続機構（本実施の形態では、一側管体５１のフランジ部と他側管体５２のフランジ部とそれらの接続部材としての締結ボルト５３）とゴムリング１１との干渉を回避することができる。 In addition, according to the present embodiment, the rubber ring 11 has a cross section having the recess 14 on the inner surface side, so that the connection mechanism between the one-side tubular body 51 and the other-side tubular body 52 (the present embodiment). Then, it is possible to avoid interference between the flange portion of the one-side tube body 51, the flange portion of the other-side tube body 52, the fastening bolt 53) as a connecting member thereof, and the rubber ring 11.
また、本実施の形態によれば、ゴムリング１１の外側面上に載置される各ハウジング２１〜３４の載置面が同一曲率の側面視円弧状となっているため、接続対象の管体５１及び５２の断面形状が真円に近い場合に当該管体上に沿った取り付けが実現される一方で、各管体５１及び５２が変形等して各管体５１及び５２の断面形状が真円から大きく逸れてしまっている場合であっても、ハウジング２１〜３４が１３個に分離していることによって、やはり管体上に沿った取り付けが実現されるようになっている。もっとも、各ハウジング２１〜３４の載置面は、側面視円弧状に限定されず、管体５１及び５２の断面形状により良く適合する適宜の形状が採用されてもよいし、ハウジングの数が多ければ、側面視平坦状の形状も採用され得る。また、ハウジングの載置面の形状は、ハウジング毎に異なっていてもよい。 Moreover, according to this Embodiment, since the mounting surface of each housing 21-34 mounted on the outer surface of the rubber ring 11 becomes a circular arc view of the same curvature side view, it is a pipe body of connection object When the cross-sectional shapes of the pipes 51 and 52 are close to a perfect circle, the attachment along the pipe body is realized. On the other hand, the pipe bodies 51 and 52 are deformed and the cross-sectional shapes of the pipe bodies 51 and 52 are true. Even when it is greatly deviated from the circle, the housings 21 to 34 are separated into 13 pieces, so that the attachment along the tubular body is also realized. However, the mounting surfaces of the respective housings 21 to 34 are not limited to the circular arc shape when viewed from the side, and an appropriate shape that better matches the cross-sectional shape of the tubular bodies 51 and 52 may be adopted, and the number of housings may be large. For example, a flat shape in a side view can be adopted. Moreover, the shape of the mounting surface of the housing may be different for each housing.
また、本実施の形態によれば、ハウジング２１〜３４の各々がゴムリング１１の両方の側方面の大部分を覆う形状を有しているため、ハウジング２１〜３４の各々によってゴムリング１１が効果的に保護される。 Moreover, according to this Embodiment, since each of the housings 21-34 has the shape which covers most of both the side surfaces of the rubber ring 11, the rubber ring 11 is effective by each of the housings 21-34. Protected.
