Description

本発明は、流体管の外周を密封状に被覆したケースと、ケース内に連通する連通部を介し挿入されて流体管に周方向に沿って穿孔を穿設する穿孔手段と、穿孔を介しケース内と流体管内とを移動自在に支持される弁体と、から構成され、弁体を流体管内に移動することで弾性変形させて流路を遮断可能な制流弁に関する。   The present invention relates to a case in which the outer periphery of a fluid pipe is covered in a sealing manner, a perforation means that is inserted through a communication portion that communicates with the inside of the case and perforates the fluid pipe in the circumferential direction, and the case through the perforation. The present invention relates to a flow control valve that is configured to include a valve body that is movably supported in the inside and the fluid pipe, and that can be elastically deformed by moving the valve body into the fluid pipe to block the flow path.

従来の制流弁には、流体管を密封した密封ケース内において、エンドミル状の切削工具から成る穿孔手段を用いて流体管の周方向に沿って開口する穿孔を穿設し、この穿孔を介し弁体を挿入操作することで、流体管の流路を遮断若しくは開放しているものがある(例えば、特許文献1参照)。   In the conventional control valve, a perforation opening along the circumferential direction of the fluid pipe is formed using a perforation means made of an end mill-shaped cutting tool in a sealed case in which the fluid pipe is sealed, and the perforation is formed through the perforation. There is one that blocks or opens the flow path of the fluid pipe by inserting and operating the valve body (see, for example, Patent Document 1).

特開2001−193893号公報(第4頁、第1図)JP 2001-193893 (page 4, FIG. 1)

しかしながら、特許文献1にあっては、穿孔手段に穿設される穿孔が、流体管の周方向に略180度の開口角度、すなわち流体管の略半周に亘り開口しているため、穿孔の形成箇所における流体管自体の構造強度が低下し、流体管の変形や破損が生じた場合は密封性が維持できない虞がある。   However, in Patent Document 1, the perforation formed in the perforation means is opened at an opening angle of about 180 degrees in the circumferential direction of the fluid pipe, that is, over a substantially half circumference of the fluid pipe. If the structural strength of the fluid pipe itself at the location is reduced and the fluid pipe is deformed or broken, the sealing performance may not be maintained.

本発明は、このような問題点に着目してなされたもので、穿孔を穿設しても流体管の構造強度を維持して密封性を確保できる制流弁を提供することを目的とする。   The present invention has been made paying attention to such problems, and an object of the present invention is to provide a flow control valve that can maintain the structural strength of the fluid pipe and ensure the sealing performance even when the perforation is formed. .

前記課題を解決するために、本発明の制流弁は、

In addition, since the support portion supports the core fitted in the perforation, the core does not come out of the perforation even when the valve body moves between the case and the fluid pipe via the core. In addition, since at least a part of the support portion is provided by being inserted into the case through the communication portion, the support portion can be inserted into the case using the communication portion, and the support portion can be inserted into the case. Easy to install.

本発明に係る制流弁を実施するための形態を実施例に基づいて以下に説明する。   EMBODIMENT OF THE INVENTION The form for implementing the control valve which concerns on this invention is demonstrated below based on an Example.

実施例に係る制流弁につき、図1から図7を参照して説明する。   The control valve according to the embodiment will be described with reference to FIGS.

図2及び図3に示すように、本発明の制流弁としての制水弁10は、主として、内部を上水が流れる流体管1の上部に穿設される穿孔Qに連通し流体管1の外周を水密に被覆したケース2と、非上昇の回動ネジ4の回転によりケース2内と流体管1との間にて上下方向、すなわち回動ネジ4の軸方向に操作される仕切弁である弁体60とを有し、流体管1の管路を遮断若しくは開放する。尚、本実施例における非上昇の回動ネジ4は、回動ネジ4自体が水平回動によって軸方向に移動しないよう設けられている。   As shown in FIGS. 2 and 3, the water control valve 10 as the current control valve of the present invention mainly communicates with a perforation Q formed in an upper portion of the fluid pipe 1 through which clean water flows. A gate valve that is operated in the vertical direction between the case 2 and the fluid pipe 1 by the rotation of the non-lifting rotating screw 4, that is, the axial direction of the rotating screw 4. And shuts off or opens the pipe of the fluid pipe 1. In this embodiment, the non-lifting turning screw 4 is provided so that the turning screw 4 itself does not move in the axial direction by horizontal turning.

本実施例の流体管1は、断面視略円形状に形成された金属製管から成り、内周面がモルタル層で被覆されている。尚、流体管の内周面はモルタル層に限らず、例えばエポキシ樹脂等により被覆されてもよく、若しくは適宜の材料を粉体塗装により流体管の内周面に被覆してもよい。また、本実施例では流体管1内の流体は上水であるが、流体管1の内部を流れる流体は必ずしも上水に限らず、例えば工業用水であってもよいし、また気体や気液混合状態の流体が流れる流体管であっても構わない。   The fluid pipe 1 of the present embodiment is made of a metal pipe formed in a substantially circular shape in cross section, and the inner peripheral surface is covered with a mortar layer. The inner peripheral surface of the fluid pipe is not limited to the mortar layer, and may be coated with, for example, an epoxy resin, or an appropriate material may be coated on the inner peripheral surface of the fluid pipe with powder coating. In the present embodiment, the fluid in the fluid pipe 1 is clean water, but the fluid flowing in the fluid pipe 1 is not necessarily limited to clean water, and may be, for example, industrial water, or may be gas or gas-liquid. It may be a fluid pipe through which a mixed fluid flows.

流体管1の外周面に正面視で流体管1の左下方に向けて傾斜して固定に取り付けられるケース2は、いわゆる割T字管であって、流体管1の管軸と略直交する内空部を備え、内部に弁体60を備えた分岐管12と、流体管1の外周の下側を被覆するカバー11と、からなる。尚、弁体60の外周面には、予め穿孔Qに嵌設するためのコア40が取り外し可能に取り付けられている。図1に示されるように、弁体60の外面にくびれ部60bが周方向に形成されており、このくびれ部60bにコア40を係合させて取り付けることで、コア40は、後述する弁体60の下方動作においては弁体60から外れてしまうことが無い。   A case 2 attached to the outer peripheral surface of the fluid pipe 1 so as to be inclined and fixed toward the lower left side of the fluid pipe 1 in a front view is a so-called split T-shaped pipe, and is an inner part that is substantially orthogonal to the pipe axis of the fluid pipe 1. It consists of a branch pipe 12 having an empty part and having a valve body 60 inside, and a cover 11 covering the lower side of the outer periphery of the fluid pipe 1. In addition, the core 40 for fitting in the perforation Q previously is attached to the outer peripheral surface of the valve body 60 so that removal is possible. As shown in FIG. 1, a constricted portion 60 b is formed in the circumferential direction on the outer surface of the valve body 60, and the core 40 is attached to the constricted portion 60 b by being engaged with the core 40 to be described later. In the downward movement of 60, it does not come off from the valve body 60.

図1に示すように、先ず分岐管12とカバー11とを、流体管1を挟む位置で対向させ、流体管1の長手方向に沿って配置された複数のボルト・ナット13により締結する。分岐管12とカバー11との間には、図示しないパッキンが設けられており、このパッキンによって分岐管12とカバー11との間は水密に保持されている。また、分岐管12には、流体管1の管軸に向けて分岐管12内と分岐管12の外方とを連通させる連通部12aが形成されている。   As shown in FIG. 1, first, the branch pipe 12 and the cover 11 are opposed to each other at a position sandwiching the fluid pipe 1 and fastened by a plurality of bolts and nuts 13 arranged along the longitudinal direction of the fluid pipe 1. A packing (not shown) is provided between the branch pipe 12 and the cover 11, and the branch pipe 12 and the cover 11 are kept watertight by this packing. Further, the branch pipe 12 is formed with a communication portion 12 a that communicates the inside of the branch pipe 12 and the outside of the branch pipe 12 toward the pipe axis of the fluid pipe 1.

次に、連通部12aのフランジ12bに、内部に作業弁36を配設した開閉部材35を水密に接続し、更に、開閉部材35の上端部に本発明における穿孔手段としての穿孔装置50を水密に接続する。穿孔装置50は、フランジ12bに水密に接続された筒体53と、図示しない筒体53の先端部に水密に接続されるとともに、図示しない駆動手段に接続され流体管1に向け軸方向に伸出するとともに軸周りに回転する軸部材51と、軸部材51の先端に固設され流体管1を穿設するドリル状のエンドミル52と、から主として構成されている。   Next, an opening / closing member 35 having a working valve 36 disposed therein is connected to the flange 12b of the communication portion 12a in a watertight manner, and a punching device 50 as a punching means in the present invention is connected to the upper end of the opening / closing member 35 in a watertight manner. Connect to. The perforating apparatus 50 is connected to a flange 53b in a watertight manner and a tip of the cylinder 53 (not shown) and is connected to a driving means (not shown) and extends in the axial direction toward the fluid pipe 1. The shaft member 51 is mainly composed of a shaft member 51 that extends and rotates around the shaft, and a drill-like end mill 52 that is fixedly provided at the tip of the shaft member 51 and pierces the fluid pipe 1.

そして、図1に示すように、エンドミル52は、軸部材51によって流体管1の外面に向けて押し込まれることで流体管1の一部を切削する。この状態から施工者がケース2を流体管1の管軸周りに正面視で時計回りに回動させることで、図2に示すように、エンドミル52が流体管1の上部をケース2の回動に伴って切削し、流体管1に上方に向けて開口する穿孔Qが形成される。   Then, as shown in FIG. 1, the end mill 52 cuts a part of the fluid pipe 1 by being pushed toward the outer surface of the fluid pipe 1 by the shaft member 51. From this state, the installer rotates the case 2 around the tube axis of the fluid pipe 1 in a clockwise direction in front view, so that the end mill 52 rotates the upper part of the fluid pipe 1 over the upper part of the fluid pipe 1 as shown in FIG. As a result, the perforation Q that cuts upward and opens upward in the fluid pipe 1 is formed.

ケース2は、施工者によって流体管1の管軸周りに略90度〜150度の角度にかけて回動され、穿孔Qの穿設が終了するとともに流体管1に対して垂直方向を向くように配置され、弁体60は穿孔Qに対して上下方向で対向配置される。このため、エンドミル52によって切削されることで形成された穿孔は、流体管1の周方向に向けて開口角度θが略90度〜150度となるように形成される。尚、一例として本実施例では穿孔Qは、開口角度θが略120度である。尚、前述のような手順で形成された穿孔Qは、図3に示すように、前後幅方向に向けて短寸であって周方向に長寸に開口するスリット状をなしている。   The case 2 is rotated around the tube axis of the fluid pipe 1 by an operator at an angle of approximately 90 to 150 degrees, and is arranged so as to face the fluid pipe 1 in the vertical direction when the drilling Q is finished. The valve body 60 is disposed to face the perforation Q in the vertical direction. For this reason, the perforations formed by cutting by the end mill 52 are formed so that the opening angle θ is approximately 90 degrees to 150 degrees in the circumferential direction of the fluid pipe 1. As an example, in this embodiment, the perforation Q has an opening angle θ of approximately 120 degrees. As shown in FIG. 3, the perforation Q formed by the above-described procedure has a slit shape that is short in the front-rear width direction and long in the circumferential direction.

次に、図4に示すように、軸部材51を引き上げることによってエンドミル52を連通部12a内から筒体53内に配置させ、作業弁36を閉塞することで連通部12aと筒体53内とを遮断するとともに、穿孔装置50を開閉部材35から取り外す。   Next, as shown in FIG. 4, the end mill 52 is disposed from the communication portion 12 a into the cylinder 53 by pulling up the shaft member 51, and the work valve 36 is closed to close the communication portion 12 a and the cylinder 53. And the piercing device 50 is removed from the opening / closing member 35.

そして、ケース2の上端部に設けられた回動操作部4aに図示しないハンドルを取り付ける。回動ネジ4は、ケース2の頂部に穿設された挿通孔32に回転自在に貫通して、上端部をケース2の外部に突出して取り付けられている。押え板33は、ケース2の上端部に下方からボルト34で固定され、回動ネジ4の抜出しを阻止する。上記構成により、回動ネジ4はケース2に対し正逆両方向に回転自在であるが上下動はしない。4bは、回動ネジ4の上端部を除いて略全長に亘ってその周面が螺設されたネジ部である。   Then, a handle (not shown) is attached to the rotation operation unit 4 a provided at the upper end of the case 2. The rotating screw 4 is rotatably attached to an insertion hole 32 formed in the top of the case 2 so that the upper end protrudes outside the case 2. The holding plate 33 is fixed to the upper end portion of the case 2 with a bolt 34 from below, and prevents the rotation screw 4 from being pulled out. With the above configuration, the rotating screw 4 is rotatable in both forward and reverse directions with respect to the case 2 but does not move up and down. Reference numeral 4b denotes a screw portion having a circumferential surface screwed over substantially the entire length except for the upper end portion of the rotating screw 4.

図1に示すように、ネジこま63は、弁体60の上端部に形成されたガイド溝61に嵌合するとともに、ネジ部4bに螺合しており、回動ネジ4の上端部に形成された回転操作部4aの回転に応じネジ部4bが回転することで、ネジ部4bに沿って螺挿するネジこま63に追随して弁体60が上下動可能となる。   As shown in FIG. 1, the screw top 63 is fitted in a guide groove 61 formed in the upper end portion of the valve body 60 and screwed into the screw portion 4 b, and is formed in the upper end portion of the rotating screw 4. By rotating the screw portion 4b according to the rotation of the rotation operation portion 4a, the valve body 60 can be moved up and down following the screw top 63 screwed along the screw portion 4b.

また、弁体60には、回動ネジ4のネジ部4bを挿入する挿入孔64が形成されている。更に、弁体60は、穿孔Qに対して挿入可能な幅寸法に形成されたゴム材等の弾性材から構成されており、弁体60の下部は、穿孔Qに挿入可能な左右幅寸法及び前後幅寸法に形成されている。尚、弁体60の上部は、下部よりも左右幅方向に凸となる突設部60aに形成されている。   Further, the valve body 60 is formed with an insertion hole 64 into which the screw portion 4b of the rotating screw 4 is inserted. Further, the valve body 60 is made of an elastic material such as a rubber material formed to have a width dimension that can be inserted into the perforation Q. It is formed in the front-rear width dimension. In addition, the upper part of the valve body 60 is formed in the protrusion part 60a which becomes convex in the left-right width direction rather than the lower part.

以後、弁体60は、図2及び図4に示すように、前記ハンドルによる回転操作部4aの水平回動によって下方に移動することで流体管1の内周面に弾性変形しながら水密に当接して流体管1の管路を遮断するとともに、前記ハンドルによる回転操作部4aの水平回動によって上方に移動することで流体管1の管路を開放するようになる。   Thereafter, as shown in FIGS. 2 and 4, the valve body 60 moves downward by horizontal rotation of the rotation operation portion 4 a by the handle, so that the valve body 60 is elastically deformed to the inner peripheral surface of the fluid pipe 1 and is watertight. The pipe of the fluid pipe 1 is released by moving upward by the horizontal rotation of the rotation operation unit 4a by the handle while being in contact with the pipe of the fluid pipe 1.

次に、図2及び図3に示すように、本実施例におけるコア40は、前後幅方向に向けて短寸であるスリット状に形成された穿孔Qと略同形状に形成され、内部が貫通形成されたフレーム41と、このフレーム41の底面の略全周に亘って配設された、弾性を有する樹脂材等からなる防錆部材42と、から構成されており、フレーム41の左右両端部には、後述する固定ボルト16を螺挿可能及び後述する固定ピン17を挿入可能な支持孔41aが形成されている。   Next, as shown in FIGS. 2 and 3, the core 40 in this embodiment is formed in substantially the same shape as the perforation Q formed in a slit shape that is short in the front-rear width direction, and the inside penetrates. The frame 41 is composed of a rust preventive member 42 made of an elastic resin material or the like, which is disposed over substantially the entire circumference of the bottom surface of the frame 41. A support hole 41a into which a fixing bolt 16 described later can be screwed and a fixing pin 17 described later can be inserted is formed.

上記構成を有する制水弁10において、コア40による穿孔Qの防錆について説明する。先ず、図4に示すように、前述したように、前記ハンドルによる回転操作部4aの水平回動によってコア40を取り付けた弁体60を、穿孔Qを介して流体管1内の内周面に弾性変形しながら水密に当接させ、流体管1の流路を遮断する。   In the water control valve 10 having the above configuration, the rust prevention of the perforation Q by the core 40 will be described. First, as shown in FIG. 4, as described above, the valve body 60 to which the core 40 is attached by the horizontal rotation of the rotation operation portion 4 a by the handle is attached to the inner peripheral surface in the fluid pipe 1 through the perforation Q. While elastically deforming, the fluid pipe 1 is brought into contact with the water tight and the flow path of the fluid pipe 1 is blocked.

このとき、コア40は、突設部60aによって穿孔Qの内周面に向けて押圧される。このため、防錆部材42が弾性変形しながら穿孔Qの内周面の全周に亘って当接し、穿孔Qの内周面の防錆がなされる。尚、穿孔Qが形成されるとともにケース2が垂直方向を向くように配置される際に弁体60が穿孔Qと上下方向で対向配置されているため、弁体60と穿孔Qとの位置決めを行うことなくコア40の穿孔Qの内周面への押圧を行うことができる。   At this time, the core 40 is pressed toward the inner peripheral surface of the perforation Q by the projecting portion 60a. For this reason, the rust preventive member 42 abuts over the entire circumference of the inner peripheral surface of the perforation Q while being elastically deformed, and the inner peripheral surface of the perforation Q is prevented from being rusted. In addition, since the valve body 60 is disposed to face the perforation Q in the vertical direction when the perforation Q is formed and the case 2 is disposed so as to face the vertical direction, the positioning of the valve body 60 and the perforation Q is performed. It is possible to press the inner peripheral surface of the perforation Q of the core 40 without performing it.

そして、図5に示すように、ケース2の左側方から本発明における支持部としての固定ボルト16をフレーム41の左端部に形成された支持孔41aに向けて螺挿する。更に、連通部12aのフランジ12bから開閉部材35を取り外すとともに、開閉部材35に替えて連通部12aのフランジ12bに蓋体54を取り付ける。この蓋体54によって連通部12aは水密に閉塞される。   Then, as shown in FIG. 5, the fixing bolt 16 as a support portion in the present invention is screwed into the support hole 41 a formed at the left end portion of the frame 41 from the left side of the case 2. Further, the opening / closing member 35 is removed from the flange 12b of the communication portion 12a, and a lid 54 is attached to the flange 12b of the communication portion 12a instead of the opening / closing member 35. The communication part 12a is watertightly closed by the lid 54.

尚、蓋体54は、連通部12aのフランジ12bと対向配置される側の側面から流体管1を向く本発明における支持部としての固定ピン17を備えている。この固定ピン17は、連通部12aが蓋体54によって水密に閉塞されると同時に、連通部12aを介してフレーム41の右端部に形成された支持孔41aに挿通される。このため、コア40は、固定ボルト16及び固定ピン17によって穿孔Qに嵌設された状態で固定され、防錆部材42による穿孔Qの内周面の防錆が維持される。   The lid body 54 includes a fixing pin 17 as a support portion in the present invention that faces the fluid pipe 1 from the side surface of the communication portion 12a facing the flange 12b. The fixing pin 17 is inserted into the support hole 41a formed in the right end portion of the frame 41 through the communication portion 12a at the same time that the communication portion 12a is watertightly closed by the lid 54. For this reason, the core 40 is fixed in a state where the core 40 is fitted to the perforation Q by the fixing bolt 16 and the fixing pin 17, and the rust prevention of the inner peripheral surface of the perforation Q by the antirust member 42 is maintained.

コア40を穿孔Qに嵌設した状態で固定した後は、図6に示すように、再び前記ハンドルによる回転操作部4aの水平回動によって弁体60を上方に移動することで流体管1の管路を開放し、一連の穿孔Qの防錆工程を完了する。尚、このとき、弁体60が上方に移動することによって弁体60とコア40との間に摩擦が生じるが、この弁体60とコア40との間に生じる摩擦に抗して固定ボルト16及び固定ピン17がコア40を穿孔Qに嵌設した状態で固定しているため、コア40は上方に移動する弁体60のくびれ部60bから取り外されることになり、すなわちコア40の穿孔Qからの離脱が阻止されるようになっている。   After the core 40 is fixed in a state where it is fitted in the perforation Q, as shown in FIG. 6, the valve body 60 is moved upward by the horizontal rotation of the rotation operation portion 4a by the handle again, so that the fluid pipe 1 The pipeline is opened, and a series of rust prevention processes for the perforated Q are completed. At this time, the valve body 60 moves upward to cause friction between the valve body 60 and the core 40. However, the fixing bolt 16 resists the friction generated between the valve body 60 and the core 40. Since the fixing pin 17 fixes the core 40 in a state where the core 40 is fitted in the perforation Q, the core 40 is removed from the constricted portion 60b of the valve body 60 moving upward, that is, from the perforation Q of the core 40. The withdrawal is prevented.

以上、本実施例における制水弁10にあっては、穿孔装置50は、流体管1に周方向に沿って略90度〜150度の開口角度θで穿孔Qを穿設するので、穿孔装置50により穿設される穿孔Qが、流体管1の半周分よりも小さい150度以下の開口角度θ度で開口していることで流体管1自体の構造強度を維持でき、且つ流体管1の四半周分である90度以上の開口角度θで開口していることで、流路を遮断する弁体60を挿入するための開口領域を十分に確保できる。   As described above, in the water control valve 10 according to the present embodiment, the perforation device 50 perforates the perforation Q in the fluid pipe 1 at an opening angle θ of about 90 to 150 degrees along the circumferential direction. The perforation Q perforated by 50 opens at an opening angle θ degree of 150 degrees or less smaller than the half circumference of the fluid pipe 1 so that the structural strength of the fluid pipe 1 itself can be maintained, and the fluid pipe 1 Opening at an opening angle θ of 90 degrees or more, which is a quarter circumference, can sufficiently secure an opening region for inserting the valve body 60 that blocks the flow path.

また、穿孔Qにコア40が嵌設されるとともに、ケース2にコア40を支持する固定ボルト16及び固定ピン17が設けられているので、固定ボルト16及び固定ピン17が穿孔Qに嵌設されたコア40を支持しているため、弁体60がコア40を介してケース2内と流体管1内とを移動しても、コア40が穿孔Qから外れることがない。   Further, since the core 40 is fitted in the perforation Q and the fixing bolt 16 and the fixing pin 17 that support the core 40 are provided in the case 2, the fixing bolt 16 and the fixing pin 17 are fitted in the perforation Q. Since the core 40 is supported, even if the valve body 60 moves between the case 2 and the fluid pipe 1 via the core 40, the core 40 does not come out of the perforation Q.

また、固定ピン17は、連通部12aを介しケース2内に挿入されてケース2に設けられるので、穿孔装置50をケース2内に挿入するための連通部12aを利用して、固定ピン17をケース内に挿入することができ、固定ピン17をケースに設け易い。   Further, since the fixing pin 17 is inserted into the case 2 via the communication portion 12a and is provided in the case 2, the fixing pin 17 is attached using the communication portion 12a for inserting the punching device 50 into the case 2. The fixing pin 17 can be easily provided in the case.

また、コア40は、弁体60の外面に取外し可能に取付けられ、弁体60の流体管1内に向けた移動により穿孔Qに嵌設されるので、コア40を嵌設するための特段の嵌設手段を要さずとも、ケース2内と流体管1内とを移動自在の弁体60を利用してコア40を穿孔Qに嵌設できる。   Further, the core 40 is detachably attached to the outer surface of the valve body 60, and is fitted into the perforation Q by the movement of the valve body 60 into the fluid pipe 1, so that a special part for fitting the core 40 is provided. The core 40 can be fitted into the perforation Q using the valve body 60 that is movable between the case 2 and the fluid pipe 1 without requiring fitting means.

以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。   Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

例えば、前記実施例では、フレーム41の左右両端部に支持孔41aを形成し、フレーム41の左端部側の支持孔41aに固定ボルト16を螺挿するとともに、フレーム41の右端部側の支持孔41aに固定ピン17を挿入してコア40を穿孔Qに嵌設した状態で固定したが、本発明の変形例として図7に示すように、ケース2の左右両端部に連通部12aを形成し、これら連通部12aを、固定ピン17を有する同一構成の蓋体54によって水密に閉塞することで、フレーム41の両支持孔41aに固定ピン17を挿入してコア40を穿孔Qに嵌設した状態で固定してもよい。   For example, in the embodiment, the support holes 41 a are formed at the left and right ends of the frame 41, the fixing bolt 16 is screwed into the support hole 41 a on the left end side of the frame 41, and the support hole on the right end side of the frame 41 is inserted. The fixing pin 17 is inserted into 41a and fixed in a state where the core 40 is fitted in the perforation Q. However, as shown in FIG. 7 as a modification of the present invention, the communication portions 12a are formed at the left and right ends of the case 2. The communication portion 12a is water-tightly closed with the lid 54 having the same configuration having the fixing pin 17, so that the fixing pin 17 is inserted into both the support holes 41a of the frame 41 and the core 40 is fitted into the perforation Q. It may be fixed in a state.

尚、このようにケース2の左右両端部に連通部12aを形成することによって、両連通部12aに開閉部材35を介して穿孔装置50(図1参照)を取り付けることが出来るので、例えば、エンドミル52の切削によって穿孔Qを形成する際に、ケース2の左右側の一方に壁面が設けられてケース2を壁面側に傾斜させて流体管1に対して取り付けることが困難な場合であっても、ケース2を壁面とは反対側に傾斜させて流体管1に取り付けるとともに、壁面とは反対側に形成された連通部12aからエンドミル52を流体管1に向けて挿入することで、ケース2を壁面に向けて回動させることによって穿孔Qを形成することができる。   In addition, by forming the communication portions 12a at the left and right end portions of the case 2 in this way, the punching device 50 (see FIG. 1) can be attached to the both communication portions 12a via the opening / closing member 35. Even when the perforation Q is formed by cutting 52, a wall surface is provided on one of the left and right sides of the case 2 and it is difficult to incline the case 2 toward the wall surface and attach it to the fluid pipe 1. The case 2 is attached to the fluid pipe 1 while being inclined to the opposite side to the wall surface, and the case 2 is inserted by inserting the end mill 52 toward the fluid pipe 1 from the communicating portion 12a formed on the opposite side to the wall surface. The perforation Q can be formed by rotating it toward the wall surface.

また、前記実施例では、防錆部材42を、弾性を有する樹脂材によって構成したが、防錆部材42の材質は、弾性を有していれば、例えばゴム材であってもよいし、エラストマー等の他の材料から成るものでも構わない。   Moreover, in the said Example, although the rust prevention member 42 was comprised with the resin material which has elasticity, the material of the rust prevention member 42 may be a rubber material, for example, if it has elasticity, and an elastomer Any other material may be used.

また、前記実施例では、穿孔Qの開口角度θを120度として形成したが、穿孔に挿入される弁体60によって流体管1の流路が遮断可能であれば、開口角度θは、90度から150度の範囲で自由に形成してよい。   In the above embodiment, the opening angle θ of the perforation Q is set to 120 degrees. However, if the flow path of the fluid pipe 1 can be blocked by the valve body 60 inserted into the perforation, the opening angle θ is 90 degrees. From 150 ° to 150 °.
