Description

本発明は、配管の管路端に配設された配管機器からの流体の漏洩を配管を稼動したまま止めることができる管路末端機器の漏洩補修継手に関する。   The present invention relates to a leak repair joint for a pipe end device capable of stopping leakage of fluid from a pipe device arranged at a pipe end of the pipe while the pipe is in operation.

水道管などの配管は、管路端に空気弁装置を配置し、空気弁装置を通して配管内に溜まる空気を放出するようにしている。空気弁装置は、そのフランジ部を管路端に設けたフランジ部にボルトナットのような固定手段により固定される。   In a pipe such as a water pipe, an air valve device is arranged at the end of the pipe line so that air accumulated in the pipe is discharged through the air valve device. The air valve device is fixed to a flange portion having a flange portion provided at a pipe end by a fixing means such as a bolt and nut.

空気弁装置は、故障することなく正常に作動している場合には、流体の漏洩という問題は発生しないが、パッキング等が破損した場合には、配管内を流れる流体が空気弁装置を通して外部に漏洩する事故が発生する。空気弁装置からの流体の漏洩を止めるには、配管の稼動を停止し、故障した空気弁装置を新しい空気弁装置に交換しなければならない。   When the air valve device is operating normally without failure, the problem of fluid leakage does not occur.However, when the packing or the like is damaged, the fluid flowing in the piping is discharged to the outside through the air valve device. A leaking accident occurs. In order to stop the leakage of fluid from the air valve device, it is necessary to stop the operation of the piping and replace the failed air valve device with a new air valve device.

配管の管路端に配設された空気弁装置からの流体の漏洩を止めるには、配管の稼動を停止し、故障した空気弁装置を新しい空気弁装置に交換しなければならないが、空気弁装置からの流体の漏洩を発見した後、直ちに配管の稼動を停止することは、配管を利用している利用者の生活に支障を来すことになるという問題点がある。   In order to stop fluid leakage from the air valve device installed at the pipe end of the piping, it is necessary to stop the operation of the piping and replace the failed air valve device with a new air valve device. Immediately after the discovery of fluid leakage from the apparatus, stopping the operation of the pipe has a problem in that it interferes with the life of the user who uses the pipe.

本発明は、上記した問題点を考慮してなされたもので、配管の管路端に配設された配管機器からの流体の漏洩を配管を稼動したまま止めることができる管路末端機器の漏洩補修継手を提供することを目的とする。   The present invention has been made in consideration of the above-mentioned problems, and leakage of a pipe end device capable of stopping leakage of fluid from a pipe device arranged at the pipe end of the pipe while the pipe is in operation. The purpose is to provide repair joints.

本発明の管路末端機器の漏洩補修継手は、上端に通気口および下端に環状取付フランジを有し配管の管路端に設けられた配管機器を囲むように配置された漏洩補修継手本体と、複数割りしたフランジ部を有し配管の管路端部を囲むように固定された押輪フランジと、漏洩補修継手本体の環状取付フランジを押輪フランジに固定する固定手段とから構成される。   The leak repair joint of the pipe end device of the present invention has a leak repair joint body arranged to surround a pipe device provided with a vent at the upper end and an annular mounting flange at the lower end and provided at the pipe end of the pipe, A push ring flange having a plurality of divided flange portions and fixed so as to surround the pipe end portion of the pipe, and a fixing means for fixing the annular mounting flange of the leak repair joint body to the push ring flange.

本発明による漏洩補修継手ば、配管の管路端に設けられた配管機器全体を囲むように配管の管路端部に固定することで、配管機器からの流体の漏洩が生じても、配管を稼動したまま配管機器からの流体の漏洩を止めることができる。   The leak repair joint according to the present invention is fixed to the pipe end of the pipe so as to surround the entire pipe equipment provided at the pipe end of the pipe, so that the pipe can be connected even if fluid leakage from the pipe equipment occurs. Leakage of fluid from piping equipment can be stopped while operating.

また、本発明による漏洩補修継手ば、配管内を断水できる状況になった時点で解体することで、配管機器の交換により発生する配管利用者の生活の支障を少なくすることができる。   Moreover, if the leak repair joint according to the present invention is dismantled when it becomes possible to shut off the inside of the pipe, it is possible to reduce troubles in the life of the pipe user that occurs due to replacement of the pipe equipment.

The push ring flange 5 can also be formed from three or more flange portions 5a. A plurality of mounting holes 5 b are formed in the pusher wheel flange 5 in correspondence with the mounting holes 8 a provided in the annular mounting flange 8. A mounting portion 5c is integrally formed at the lower end of each flange portion 5a. Each flange part 5a, 5a is arrange | positioned so that the pipe line end 2a of the piping 2 may be enclosed, and it mutually connects by the fixing means 11 like a bolt nut.

上記漏洩補修継手本体４は、環状取付フランジ８に設けた複数の取付孔８ａが押輪フランジ５に設けた複数の取付孔８ａに整合するように配管２の管路端２ａに固定した押輪フランジ５の上面に配置され、環状取付フランジ８に設けた取付孔８ａおよび押輪フランジ５に設けた取付孔８ａを挿通するボルトナットのような固定手段１２により押輪フランジ５に連結される。これにより、漏洩補修継手本体４の環状取付フランジ８は、環状シール１０を介して押輪フランジ５に液密に固定される。また、押輪フランジ５と管路端２ａの間には、空気弁装置３から漏洩する流体が配管２側に漏れるの防ぐためのゴムリング１３が配置される。   The leak repair joint body 4 includes a push ring flange 5 fixed to the pipe end 2 a of the pipe 2 so that a plurality of attachment holes 8 a provided in the annular attachment flange 8 are aligned with a plurality of attachment holes 8 a provided in the push ring flange 5. The mounting hole 8a provided in the annular mounting flange 8 and the fixing means 12 such as a bolt and nut that passes through the mounting hole 8a provided in the pressing wheel flange 5 are connected to the pressing wheel flange 5. As a result, the annular mounting flange 8 of the leakage repair joint body 4 is liquid-tightly fixed to the pusher wheel flange 5 via the annular seal 10. Further, a rubber ring 13 is disposed between the pusher wheel flange 5 and the pipe end 2a to prevent fluid leaking from the air valve device 3 from leaking to the pipe 2 side.

上記空気弁装置３は、図２に示すように、そのフランジ３ａを配管２の管路端２ａのフランジ２ｂにボルトナットのような固定手段１４により取り付けられる。   As shown in FIG. 2, the air valve device 3 has its flange 3 a attached to the flange 2 b of the pipe end 2 a of the pipe 2 by a fixing means 14 such as a bolt and nut.

なお、上記実施の態様では、管路末端機器として空気弁装置を例として説明したが、計測装置のような他の装置であつてもよい。 In the above embodiment, the air valve device has been described as an example of the pipe terminal device, but another device such as a measuring device may be used.

つぎに、本発明による管路末端機器の漏洩補修継手１の配管２の管路端２ａへの取付手順について説明する。   Below, the attachment procedure to the pipe end 2a of the piping 2 of the leak repair joint 1 of the pipe terminal equipment by this invention is demonstrated.
