Description
【０００１】[0001]
本考案は例えばガス管の修理或いは敷設工事等の終了後にその管端に取り付け て配管内にガスを強制的に送り込み、配管内に残留している空気を抜く所謂エア パージ作業や、あるいは継手を介して樹脂枝管を樹脂本管に融着した後の気密性 の確認作業（気密試験）に用いられる封止具に関する。 The present invention is, for example, a so-called air purging work for attaching a gas pipe to the pipe end after the completion of repair or laying work of the gas pipe to forcibly send gas into the pipe and removing air remaining in the pipe, or a joint. The present invention relates to a sealing tool used for a work of checking airtightness (airtightness test) after a resin branch pipe is fused and bonded to a resin main pipe via.
【０００２】[0002]
このようなエアパージ作業や気密確認作業においては、封止ストッパを管端に 取り付けて管端を封止する必要がある。 従来の封止具は筒状本体の外周に取り付けた相対接近、離反可能な一対のフラ ンジ部材間にゴム材を挟持し、このフランジ部材を管の軸線方向に締め付けてい くことによりゴム材を圧縮し径方向に膨張させる。その結果、このゴム材の外周 部が樽状に広がり、管の内周に強く押し付けられ気密を確保する。 In such air purging work and airtightness confirmation work, it is necessary to attach a sealing stopper to the pipe end to seal the pipe end. In the conventional sealing tool, a rubber material is sandwiched between a pair of flange members attached to the outer periphery of the tubular body and capable of relatively approaching and separating, and the flange member is clamped in the axial direction of the pipe to secure the rubber material. Compress and expand radially. As a result, the outer periphery of this rubber material spreads in a barrel shape and is strongly pressed against the inner periphery of the pipe to ensure airtightness.
【０００３】[0003]
しかるに、このような従来の封止具にあっては、封止具本体の管内周面への取 付けは径方向に膨張するゴム材のみにより行なわれているため、管に気密試験時 のエア内圧がかかると抜けてしまうという問題があった。即ち、ゴムは管の内周 に圧着されることにより、管との気密性を確保すると同時に管に対する内径チャ ックの役割も果たしていた。上記のエアパージ作業や気密試験では、封止具の外 端に取り付けられるエア供給管を介して所定圧力のエアを配管内部に送り込むこ とになるが、そのエア内圧がある程度の大きさ（例えば、１kg／cm2 ）の場合に は、ゴムの保持力だけでは不十分となり、封止具が配管から抜けてしまう。However, in such a conventional closure, since the attachment of the main body of the closure to the inner peripheral surface of the pipe is performed only by the rubber material that expands in the radial direction, the pipe is not air-sealed during the airtight test. There was a problem that it would come off when internal pressure was applied. That is, the rubber was pressure-bonded to the inner circumference of the pipe to ensure airtightness with the pipe, and at the same time, played a role of an inner diameter chuck for the pipe. In the above-mentioned air purging work and airtightness test, air of a predetermined pressure is sent into the inside of the pipe through the air supply pipe attached to the outer end of the sealing tool, but the internal pressure of the air has a certain level (for example, In the case of 1 kg / cm 2 ), the rubber holding force is not enough and the sealing tool will come out of the pipe.
【０００４】[0004]
本考案の目的は上述の如き問題点を解決し、確実な気密保持と同時に抜け止め 防止可能な簡易封止具を提供することにある。 本考案の基本構想は、気密部材（上記のゴム材に相当）とは別個に管の内径保 持部材を設けることにより問題の解決を図ったことにある。 上記目的を達成するために、本考案にかかる封止具は、取り付けるべき管の内 径内に挿入される中心孔付き筒状本体と、上記筒状本体の外周上に取り付けられ る軸線方向に相対的に可動な一対のフランジ部材と、これらフランジ部材間に挿 着され両フランジ部材の相対接近により圧縮されて径方向に膨張し管の内周に押 し付けられる弾性封止部材と、上記筒状本体の外周上に取り付けられ、軸線方向 の押圧力を受けて径方向に拡開して管の内周に押し付けられる内径チャック用コ レット部材と、上記コレット部材及びフランジ部材に軸線方向の押圧力を加える 加圧部材とを有することを構成上の特徴とする。 An object of the present invention is to solve the above-mentioned problems and to provide a simple sealing device capable of reliably holding airtightness and at the same time preventing the retaining. The basic concept of the present invention is to solve the problem by providing an inner diameter holding member for the tube separately from the airtight member (corresponding to the rubber material described above). In order to achieve the above-mentioned object, a sealing device according to the present invention comprises a tubular body with a central hole inserted into the inner diameter of a pipe to be attached, and an axial direction attached to the outer periphery of the tubular body. A pair of relatively movable flange members, an elastic sealing member that is inserted between these flange members and is compressed by the relative approach of both flange members, expands in the radial direction, and is pressed against the inner circumference of the pipe; An inner diameter chuck collet member that is mounted on the outer circumference of the tubular body, expands in the radial direction when pressed by the axial force, and is pressed against the inner circumference of the pipe, and the collet member and the flange member in the axial direction. A structural feature is that it has a pressing member that applies a pressing force.
【０００５】 好ましくは、上記加圧部材はナット部材により構成され、上記筒状本体の外周 には該ナット部材が螺合する外周ねじが形成される。 更に、上記筒状本体の一端にエア供給管を接続するための取付けねじ孔を形成 すれば、ここにエア供給管を簡単に接続することが出来る。Preferably, the pressing member is composed of a nut member, and an outer peripheral screw with which the nut member is screwed is formed on the outer periphery of the tubular main body. Further, if an attaching screw hole for connecting the air supply pipe is formed at one end of the cylindrical body, the air supply pipe can be easily connected thereto.
【０００６】[0006]
本考案によれば、弾性封止部材に加え、弾性封止部材と同様に軸線方向の押圧 力を受けて径方向に拡開して管の内周に押し付けられる内径チャック用コレット 部材が設けられるので、管への保持力は弾性封止部材のみならずこのコレット部 材により確保され、従って、配管に大きな内圧が作用しても封止具が抜け落ちる 心配はない。管の気密性は従来と同様に弾性封止部材により確保される。 また、加圧部材をナット部材により構成すれば、このナット部材を相対回転さ せることによりナット部材が封止具本体に相対的に管軸線方向に動き、弾性封止 部材及びコレット部材を軸線方向に押圧することができる。その結果、弾性封止 部材及びコレット部材の管径方向への拡開が生じ、共に管内周に強く圧接せしめ られる。 According to the present invention, in addition to the elastic sealing member, the collet member for the inner diameter chuck is provided which, like the elastic sealing member, receives the pressing force in the axial direction and expands radially and is pressed against the inner circumference of the pipe. Therefore, the holding force to the pipe is secured not only by the elastic sealing member but also by this collet member, and therefore, even if a large internal pressure acts on the pipe, there is no concern that the sealing tool will fall out. The airtightness of the tube is ensured by the elastic sealing member as in the conventional case. Further, if the pressurizing member is composed of a nut member, the nut member moves in the pipe axis direction relative to the main body of the sealing tool by rotating the nut member relative to each other, and the elastic sealing member and the collet member move in the axial direction. Can be pressed. As a result, the elastic sealing member and the collet member expand in the radial direction of the pipe, and both are strongly pressed against the inner circumference of the pipe.
【０００７】[0007]
【実施例】 以下、添付図面を用いて本考案の実施例を詳細に説明する。 図１〜３において、管端封止具は例えば、ガス管等の管Ｐの一端の開口内に挿 入される筒状の本体１１を有し、該本体１１にはその中心にガス通路を形成する 貫通孔１３が形成されている。本体１１の外端（図の右端）にはテーパねじ孔１ ５が形成され、そこにナット２１を有するカプラ１９がナット２１により着脱自 在に固定される。カプラ１９には外部から管Ｐ内に例えば気密試験用のエアを供 給するエア供給管（図示せず）が必要に応じて取り付けられる。Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3, the pipe end sealer has, for example, a tubular main body 11 that is inserted into an opening at one end of a pipe P such as a gas pipe, and the main body 11 has a gas passage at its center. A through hole 13 to be formed is formed. A taper screw hole 15 is formed at the outer end (right end in the figure) of the main body 11, and a coupler 19 having a nut 21 therein is detachably fixed by the nut 21. An air supply pipe (not shown) for supplying air for airtightness test to the inside of the pipe P from the outside is attached to the coupler 19 as needed.
【０００８】 本体１１にはその外周の一部に外周ねじ２３が形成され、ここにナット部材２ ５が螺合せしめられる。ナット部材２５は後述の如く、弾性封止部材３５とコレ ット部材４３を管Ｐの軸線Ｘ方向に押圧する加圧手段を構成する。ナット部材２ ５の外周には好ましくはハンドルレバー２７が固設され、作業者がナット部材２ ５を回転させるときに小さな力で簡単に行なえるようにする。ナット部材２５の 一端面（図の左端面）側において、本体１１の外周上にはスラストワッシャ２９ が軸線Ｘ方向に可動に設けられ、ナット部材２５により図において左方に押され た時に同方向に動く。尚、スラストワッシャ２９は必ずしも必要ない。An outer peripheral screw 23 is formed on a part of the outer periphery of the main body 11, and a nut member 25 is screwed into the outer peripheral screw 23. The nut member 25 constitutes a pressing means for pressing the elastic sealing member 35 and the collet member 43 in the direction of the axis X of the pipe P, as described later. A handle lever 27 is preferably fixed to the outer periphery of the nut member 25 so that an operator can easily rotate the nut member 25 with a small force. A thrust washer 29 is movably provided on the outer periphery of the main body 11 in the direction of the axis X on the one end face (left end face in the drawing) of the nut member 25, and when the nut washer is pushed leftward in the drawing, the thrust washer 29 is moved in the same direction. Move to. The thrust washer 29 is not always necessary.
【０００９】 スラストワッシャ２９の左方には本考案の特徴であるコレット部材４３が設け られる。コレット部材４３自体は公知のコレットチャックに用いられるものでよ く、例えば図に示す如く、滑らかな楔型接触面を有する一対のコレット素子４３ ａ、４３ｂ（内筒、外筒）からなるもの等が使用できる。その場合、例えばコレ ット素子４３ａが周方向に３つあるいは４つに分割され、軸線Ｘ方向の力を受け た時に管径方向に拡開する。図示実施例では、内側のコレット素子４３ｂがスラ ストワッシャ２９を介してナット部材２５により左方に押されるとコレット素子 ４３ａ、４３ｂ間の楔作用により外側のコレット素子４３ａが径方向に移動し、 図２に示す状態（圧縮前）から図３に示す状態（圧縮後）に移行する。即ち、図 ３の状態では、コレット部材４３は管Ｐの内周を内径側から強く保持する内径チ ャックとして作用する。コレット部材４３は軸線方向の力を受けた時に径方向に 拡開するものであれば特に特定のものに限定されない。A collet member 43, which is a feature of the present invention, is provided on the left side of the thrust washer 29. The collet member 43 itself is not used in a well-known collet chuck, and is composed of a pair of collet elements 43a and 43b (inner cylinder, outer cylinder) having a smooth wedge-shaped contact surface as shown in the figure. Can be used. In that case, for example, the collet element 43a is divided into three or four in the circumferential direction, and expands in the pipe radial direction when receiving a force in the axis X direction. In the illustrated embodiment, when the inner collet element 43b is pushed to the left by the nut member 25 via the thrust washer 29, the outer collet element 43a is moved in the radial direction by the wedge action between the collet elements 43a, 43b. The state shown in 2 (before compression) shifts to the state shown in FIG. 3 (after compression). That is, in the state of FIG. 3, the collet member 43 acts as an inner diameter chuck that strongly holds the inner periphery of the pipe P from the inner diameter side. The collet member 43 is not particularly limited as long as it expands radially when it receives a force in the axial direction.
【００１０】 尚、４９はコレット素子４３ａがばらばらになるのを防止するＯリング４９で ある。外側コレット素子４３ａの外周面は滑り止めのためにローレット加工等を 施すことも可能である。前述の如く、スラストワッシャ２９を設けることなく、 ナット部材２５により内側コレット素子４３ｂを直接押圧することも可能である 。Reference numeral 49 is an O-ring 49 for preventing the collet element 43a from coming apart. The outer peripheral surface of the outer collet element 43a may be knurled or the like to prevent slippage. As described above, the inner collet element 43b can be directly pressed by the nut member 25 without providing the thrust washer 29.
【００１１】 コレット部材４３の更に左方には、本体１１の外周上に相対的に接近、離反可 能な一対のフランジ部材５１、５３が設けられ、その間に比較的軟いゴム等によ り形成した略樽状の弾性封止部材３５が配設される。図示実施例では第１フラン ジ部材５１が軸線Ｘ方向に可動であり、第２フランジ部材５３が固定である。尚 、両フランジ部材とも可動でもよい。但し、いずれの場合も、第２フランジ部材 ５３は図において、左方には動き得ない。即ち、第２フランジ部材５３は本体１ １の内端（図の左端）に例えばノックピン６１により固定されたストップカラー ６３により左方への動きを阻止される。Further to the left of the collet member 43, there is provided a pair of flange members 51 and 53 which can be relatively approached and separated from each other on the outer circumference of the main body 11, and a relatively soft rubber or the like is provided between them. The formed substantially barrel-shaped elastic sealing member 35 is disposed. In the illustrated embodiment, the first flange member 51 is movable in the direction of the axis X, and the second flange member 53 is fixed. Both flange members may be movable. However, in any case, the second flange member 53 cannot move to the left in the figure. That is, the second flange member 53 is prevented from moving to the left by the stop collar 63 fixed to the inner end (left end in the figure) of the main body 11 by a knock pin 61, for example.
【００１２】 弾性封止部材３５はその自由状態において、図１では円筒体として描かれてい る（それでも一向に差し支えない）が、実際上は好ましくは図２に示す如く僅か に径方向外側に膨らんだ樽型をしている。 弾性封止部材３５は一対のフランジ部材５１、５３間に挟み込まれ、図２に示 す圧縮前の状態から両フランジ部材が接近する方向に締め付けられた時に、径方 向外側に膨張（弾性変形）し、図３に示す如く、その中央部が外方に大きく膨ら んだ顕著な樽形状を呈する。その結果、弾性封止部材３５は管Ｐの内周に内側か ら強く押し付けられ、管Ｐに対する気密性を確保する。In its free state, the elastic sealing member 35 is depicted as a cylindrical body in FIG. 1 (although it does not matter which way it is), but in reality it preferably bulges slightly outward in the radial direction as shown in FIG. It has a barrel shape. The elastic sealing member 35 is sandwiched between the pair of flange members 51 and 53, and expands (elastically deforms) outward in the radial direction when both flange members are tightened in the approaching direction from the state before compression shown in FIG. As shown in FIG. 3, the center part of the container has a remarkable barrel shape that bulges outward. As a result, the elastic sealing member 35 is strongly pressed against the inner circumference of the pipe P from the inside, and the airtightness of the pipe P is secured.
【００１３】 内側コレット素子４３ｂの先端面と第１フランジ部材５１との間には復帰圧縮 ばね６９が設けられ、内側コレット素子４３ｂを常に図において右方（初期位置 側）に付勢している。尚、ばね６９は第１フランジ部材５１に切欠きを設けて第 １フランジ部材５１の代わりに弾性封止部材３５に直接当接させたり、あるいは 本体１１と内側コレット素子４３ｂとの間に設けてもよい。また、圧縮ばねの代 わりに引張ばねとして内側コレット素子４３ｂを図において右方に引っ張るよう にすることも可能である。要は内側コレット素子４３ｂに図において右方の復帰 力を付与するものであればよい。また、弾性封止部材３５自身が弾性復原力を有 するので、復帰ばね６９等の特別な復帰手段を省略することも可能である。A return compression spring 69 is provided between the tip surface of the inner collet element 43b and the first flange member 51, and always urges the inner collet element 43b to the right (to the initial position side) in the drawing. . The spring 69 may be formed by notching the first flange member 51 so as to directly contact the elastic sealing member 35 instead of the first flange member 51, or provided between the main body 11 and the inner collet element 43b. Good. Further, instead of the compression spring, the inner collet element 43b can be pulled rightward in the drawing as a tension spring. What is essential is that the inner collet element 43b is applied with a rightward restoring force in the figure. Further, since the elastic sealing member 35 itself has elastic restoring force, it is possible to omit a special returning means such as the returning spring 69.
【００１４】 弾性封止部材３５はナット部材２５による外力が解放された時に（即ち、ナッ ト部材２５を解放方向に回した時に）、その弾性復元力により図２に示す自由状 態に復帰し、この時、内側コレット素子４３ｂはばね６９の力により右方の初期 位置に向かって押し戻される。その結果、外側コレット素子４３ａも径方向に縮 み元の状態（図２）に戻る。 尚、図１において、２８は本体１１の適所に設けられるグリップであるが、ハ ンドルレバー２７を持ってナット部材２５を所定方向に回転する時に他方の手で このグリップ２８を掴めば作業がし易い。しかしながら、このグリップ２８は必 ずしも必要ない。The elastic sealing member 35 returns to the free state shown in FIG. 2 by its elastic restoring force when the external force by the nut member 25 is released (that is, when the nut member 25 is rotated in the releasing direction). At this time, the inner collet element 43b is pushed back toward the right initial position by the force of the spring 69. As a result, the outer collet element 43a also returns to the original state (FIG. 2) of contracting in the radial direction. In FIG. 1, reference numeral 28 denotes a grip provided at an appropriate position of the main body 11, but when the handle member 27 is rotated to rotate the nut member 25 in a predetermined direction, if the grip 28 is grasped by the other hand, the work is easy. . However, this grip 28 is not absolutely necessary.
【００１５】 弾性封止部材３５の外径は図３に示す如く、管Ｐに挿入しない状態で軸線方向 に圧縮、径方向に膨張させたときにコレット部材４３の最大外径よりも僅かに大 きくなるような値である。そうすることにより、実際に管Ｐ内で弾性封止部材３ ５を圧縮、膨張させた時に管Ｐに弾性的に圧接され得る。As shown in FIG. 3, the outer diameter of the elastic sealing member 35 is slightly larger than the maximum outer diameter of the collet member 43 when the elastic sealing member 35 is axially compressed and radially expanded without being inserted into the pipe P. It is a value that makes you feel better. By doing so, when the elastic sealing member 35 is actually compressed and expanded in the pipe P, the elastic sealing member 35 can be elastically pressed against the pipe P.
【００１６】 以上の如く構成した簡易管端封止具は次の如く作動する。 初めに、封止具全体を図１に示す如く管Ｐ内に挿入する。挿入深さは少なくと もコレット部材４３が管Ｐ内に没するまで入れる。そこで、ハンドルレバー２７ を持ってナット部材２５を所定方向に回す。その結果、図２に示す位置から内側 コレット素子４３ｂがばね６９のばね力に抗してスラストワッシャ２９を介して 左方に押され、その時外側コレット素子４３ａが径方向外側に拡開する。それと 同時に、ばね６９及び第フランジ部材５１を介して、弾性封止部材３５が軸線Ｘ 方向に圧縮され、その結果、径方向外側に膨張する。The simple pipe end sealer configured as described above operates as follows. First, the entire closure is inserted into the tube P as shown in FIG. Insert the collet member 43 at least at the insertion depth until it is submerged in the pipe P. Then, the handle member 27 is held and the nut member 25 is rotated in a predetermined direction. As a result, the inner collet element 43b is pushed leftward from the position shown in FIG. 2 through the thrust washer 29 against the spring force of the spring 69, at which time the outer collet element 43a expands radially outward. At the same time, the elastic sealing member 35 is compressed in the direction of the axis X 2 via the spring 69 and the flange member 51, and as a result, expands radially outward.
【００１７】 コレット部材４３の外側コレット素子４３ａが管Ｐの内径に当接すると、コレ ット部材はもはやそれ以上動けない。即ち、ナット部材２５をそれ以上回転させ ることは出来ない。この時点では、弾性封止部材３５は管Ｐの内径に強く押し付 けられている。斯くして、管Ｐはコレット部材４３によりその内径側からしっか りと保持されると共に、弾性封止部材３５により気密保持される。尚、以上の説 明から明らかな如く、弾性封止部材３５は封止機能のみならず、従来技術と同様 に管Ｐの内径掴持手段としても機能する。他方、コレット部材４３は管Ｐの内径 掴持手段として機能する。When the outer collet element 43a of the collet member 43 abuts the inner diameter of the tube P, the collet member can no longer move. That is, the nut member 25 cannot be rotated any further. At this point, the elastic sealing member 35 is strongly pressed against the inner diameter of the pipe P. Thus, the pipe P is firmly held from the inner diameter side by the collet member 43, and is airtightly held by the elastic sealing member 35. As is clear from the above description, the elastic sealing member 35 has not only a sealing function, but also functions as an inner diameter gripping means of the pipe P as in the prior art. On the other hand, the collet member 43 functions as a means for holding the inner diameter of the pipe P.
【００１８】 尚、以上の実施例ではナット部材２５を回転させて内側コレット素子４３ｂを 軸線方向に押す構成となっているが、逆にナット部材２５を固定側とし、本体１ １を回転させるようにしてもよい。その場合には、本体１１を回転させてナット 部材に対し右方に動かし、弾性封止部材３５を第２フランジ部材５３側から圧縮 することになる。即ち、図示実施例と作動が丁度逆になるだけで、作用、効果は 全く同一である。In the above embodiment, the nut member 25 is rotated to push the inner collet element 43b in the axial direction. However, conversely, the nut member 25 is fixed and the main body 11 is rotated. You may In that case, the main body 11 is rotated and moved rightward with respect to the nut member, and the elastic sealing member 35 is compressed from the second flange member 53 side. That is, the operation and effect are exactly the same, except that the operation is just opposite to that of the illustrated embodiment.
【００１９】[0019]
以上に記載した通り、本考案によれば、弾性封止手段に気密作用と管内径保持 作用との双方を依存していた従来技術に比較し、弾性封止手段とは別個に管内径 保持手段を設けたので、気密性を損なうことなく保持機能を確実にし、従って、 内圧を受けた時の封止具の管からの抜けという問題は解消される。 As described above, according to the present invention, in comparison with the prior art in which both the airtight action and the pipe inner diameter holding action depend on the elastic sealing means, the pipe inner diameter holding means is provided separately from the elastic sealing means. Is provided, the holding function is ensured without impairing the airtightness, and thus the problem of the sealing tool coming off the tube when subjected to internal pressure is eliminated.
