【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ガス管、水道管などの各種流体導管を形成
する管、継手、弁などの流路形成体において、漏洩部を
補修するために、流路形成体の漏洩部をカバーで覆い、
そのカバーの内部に硬化性のシール剤を注入する流路形
成体の修繕方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is for repairing a leak portion in a flow path forming body such as a pipe, a joint or a valve forming various fluid conduits such as a gas pipe and a water pipe. Then, cover the leak portion of the flow path forming body with a cover,
The present invention relates to a method for repairing a flow path forming body in which a curable sealing agent is injected into the inside of the cover.
従来、流路形成体の外面を単純にカバーで覆い、カバ
ーの内部に単純に硬化性のシール剤を充填していた。Conventionally, the outer surface of the flow path forming body is simply covered with a cover, and the inside of the cover is simply filled with a curable sealant.
しかし、漏洩流体の圧力が高い場合、カバー内に注入
したシール剤が硬化する迄はカバーに大きな内圧が作用
し、カバーとして耐圧性に優れた高価なものが必要とな
り、カバー経費節減面で一層の改良の余地があった。However, when the pressure of the leaked fluid is high, a large internal pressure acts on the cover until the sealant injected into the cover hardens, and an expensive cover with excellent pressure resistance is required, which further reduces the cost of the cover. There was room for improvement.
本発明の目的は、たとえ漏洩流体が高圧であっても、
耐圧性の低い安価なカバーによって良好に漏洩部を修繕
できるようにする点にある。It is an object of the present invention to provide an
An advantage of the present invention is that the inexpensive cover having low pressure resistance allows the leakage part to be satisfactorily repaired.
本発明の特徴手段は、 流路形成体の漏洩部をカバーで覆い、そのカバーの内

において、 前記カバー内で前記漏洩部の近傍から前記カバーの外
部に漏洩流体を排出する管を、前記シール剤の注入前に
セットし、 前記カバー内に注入したシール剤が硬化した後で、前
記漏洩流体排出用の管を閉塞することにあり、その作用
効果は次の通りである。A feature of the present invention is a method for repairing a flow path forming body that covers a leak portion of the flow path forming body with a cover and injects a hardening sealant into the cover, in the cover, in the vicinity of the leaking section. A pipe for discharging the leakage fluid from the outside of the cover is set before the injection of the sealing agent, and after the sealing agent injected into the cover is cured, the pipe for discharging the leakage fluid is closed. The effects are as follows.
漏洩部をカバーで覆った状態ではシール剤注入用開口
や漏洩流体排出用の管により漏洩流体をカバー外に流出
させることができ、また、カバー内にシール剤を注入し
た状態では、入口が漏洩部の近傍に位置する管により漏
洩流体をカバー外に流出させることができる。When the leaking part is covered with the cover, the leaking fluid can flow out of the cover by the sealant injection opening and the leaking fluid discharge pipe, and when the sealant is injected into the cover, the inlet leaks. Leakage fluid can flow out of the cover by a tube located in the vicinity of the part.
したがって、たとえ漏洩流体が高圧であっても、シー
ル剤が硬化する前にカバーに高圧が作用することを防止
できる。Therefore, even if the leakage fluid is at a high pressure, it is possible to prevent the high pressure from acting on the cover before the sealant hardens.
また、管の閉塞をシール剤が硬化した後で実行するか
ら、管閉塞状態での漏洩部からの圧力を硬化したシール
剤で受けさせてカバーにかからないようにできる。Further, since the pipe is closed after the sealant is hardened, the pressure from the leak portion in the pipe closed state can be received by the hardened sealant so as not to be applied to the cover.
要するに、たとえ漏洩流体が高圧であっても、その高
圧をカバーにかけないで、硬化したシール剤と、管に注
入して硬化させたシール剤や管を閉じる栓とによって、
漏洩部を良好に修繕でき、カバーを耐圧性の低い安価な
もので済ませられる。In short, even if the leakage fluid is at high pressure, without applying the high pressure to the cover, the cured sealing agent and the sealing agent injected into the tube and the stopper for closing the tube,
The leak can be repaired satisfactorily, and the cover can be inexpensive with low pressure resistance.
その結果、カバーの内部に硬化性のシール剤を注入し
て流路形成体の漏洩部を修繕する方法を、カバーに要す
る経費を十分に節減できる、経済性において一段と有利
なものに改良できた。As a result, the method of repairing the leaked portion of the flow path forming body by injecting a hardening sealant into the inside of the cover can be improved to a more economically advantageous one that can sufficiently reduce the cost required for the cover. .
