ところで、原子炉設備では、配管同士の溶接接続又は容器や弁と配管との溶接接続では、全周破断の発生を考慮する必要があるが、配管同士や容器や弁と配管との接続を、ボルトを用いたフランジ接続することで全周破断は回避できる。 By the way, in nuclear reactor facilities, it is necessary to consider the occurrence of all-round rupture in welded connections between pipes or welded connections between containers or valves and pipes. Flange connection using bolts can avoid all-round breakage.

即ち、溶接とボルトによる二重接続構造とすることで全周破断が回避できるが、上記したフランジ接続では、配管同士や容器や弁と配管との接続部からのリークポテンシャルが高くなる問題があった。 In other words, the double connection structure using welding and bolts can avoid the breakage of the whole circumference, but the above-described flange connection has the problem of increasing the leakage potential from the connection between the pipes and the connection between the container and the valve and the pipe. rice field.

上述した特許文献1には、熱伸び差を免れることのできない管部材同士を接合するに際し、流体漏れを防ぐことのできる管部材同士の接合構造が記載されているが、フランジ部からの流体リークのリスクを更に回避するためには、未だ改善の余地がある。 The above-mentioned Patent Document 1 describes a joining structure between pipe members that can prevent fluid leakage when joining pipe members that cannot avoid a difference in thermal expansion, but fluid leakage from the flange portion is described. There is still room for improvement in order to further avoid the risk of

本発明は上述の点に鑑みなされたもので、その目的とするところは、溶接部の熱応力を抑制して溶接部の接続強度を高めつつ、接続の強度(信頼性)を溶接と接続部サポートの両方で確保し、全周破断防止とフランジ部からの流体リークのリスクを回避できる容器又は配管接続機構を提供することにある。 The present invention has been made in view of the above points, and its object is to improve the strength (reliability) of the connection between the weld and the joint while suppressing the thermal stress of the weld and increasing the connection strength of the weld. To provide a container or pipe connection mechanism that secures both support, prevents breakage around the circumference, and avoids the risk of fluid leakage from a flange.

本発明の容器又は配管接続機構は、上記目的を達成するために、2つの容器又は配管の軸方向に突出した部分を突き合わせ、その突合せ部分が溶接により接続されている容器又は配管接続機構であって、2つの前記容器又は配管の軸方向に突出した部分の接続部近傍のそれぞれに、前記溶接部を挟んで相対向するように接続部サポートを設け、相対向する前記接続部サポートの外周側に、相対向する前記接続部サポート同士を接続する接続部材が設置されていることを特徴とする。 In order to achieve the above object, the container or pipe connection mechanism of the present invention is a container or pipe connection mechanism in which the portions protruding in the axial direction of two containers or pipes are butted together and the butted portions are connected by welding. In each of the vicinity of the connecting portion of the portion protruding in the axial direction of the two containers or pipes, a connecting portion support is provided so as to face each other with the weld portion interposed therebetween, and the outer peripheral side of the connecting portion support facing each other. , a connection member is installed to connect the connection portion supports facing each other.

本発明によれば、接続部サポートにより溶接部の熱応力を抑制し溶接部の接続強度を高めつつ、接続の強度(信頼性)を溶接と接続部サポートの両方で確保し、全周破断防止とフランジ部からの流体リークのリスクを回避できる。 According to the present invention, the joint support suppresses the thermal stress of the welded part and increases the connection strength of the welded part, while ensuring the strength (reliability) of the connection by both the welding and the joint support, thereby preventing the breakage of the entire circumference. and the risk of fluid leakage from the flange can be avoided.

以下、図示した実施例に基づいて本発明の容器又は配管接続機構を説明する。なお、各実施例において、同一構成部品には同符号を使用する。 Hereinafter, the container or piping connection mechanism of the present invention will be described based on the illustrated embodiments. In addition, in each embodiment, the same symbols are used for the same components.

また、以下で説明する実施例は、容器1と弁箱2との接続機構を例にして説明するが、本発明は、容器1と弁箱2との接続機構に限定されるものでは無く、配管と配管、容器と配管、弁箱と配管等、他の要素との接続機構にも適用可能である。 In the embodiments described below, the connecting mechanism between the container 1 and the valve box 2 will be described as an example, but the present invention is not limited to the connecting mechanism between the container 1 and the valve box 2. It can also be applied to a connection mechanism with other elements such as piping and piping, container and piping, valve box and piping.

図1に、本発明の容器又は配管接続機構の実施例1を示す。該図に示す本実施例は、容器1と弁箱2間の接続機構である。 FIG. 1 shows Example 1 of the container or piping connection mechanism of the present invention. The present embodiment shown in the figure is a connection mechanism between the container 1 and the valve body 2 .

図1に示す本実施例の容器1と弁箱2間の接続機構において、容器1の管部材3は、容器1のノズル部1aから溶接接続無しに軸方向に延長された部分(軸方向に突出した部分)であり、一方、弁箱2の管部材4は、弁箱2から溶接接続無しに軸方向に延長された部分(軸方向に突出した部分)であり、容器1の管部材3と弁箱2の管部材4は、それぞれ溶接部10から少なくとも2T以上(Tは、弁箱2の管部材4又は容器1の管部材3の厚み)離れた位置(図1の距離“W”離れた位置)に円盤状の接続部サポート7と8を備えている(以下で説明する実施例2及び3も同様である)。 In the connection mechanism between the container 1 and the valve box 2 of this embodiment shown in FIG. 1, the pipe member 3 of the container 1 is a portion (axial On the other hand, the pipe member 4 of the valve body 2 is a portion that extends axially from the valve body 2 without a welded connection (a portion that protrudes in the axial direction), and the pipe member 3 of the container 1 and the pipe member 4 of the valve body 2 are located at a distance of at least 2T (T is the thickness of the pipe member 4 of the valve body 2 or the pipe member 3 of the container 1) from the welded portion 10 (the distance "W" in FIG. 1). spaced apart) are provided with disk-shaped connection supports 7 and 8 (the same is true for the second and third embodiments described below).

上記した接続部サポート7と8が、容器1の管部材3と弁箱2の管部材4の溶接部10から少なくとも2T以上離れた位置(図1の距離“W”離れた位置)に固定されているのは、容器1の管部材3と弁箱2の管部材4の溶接後の溶接検査(例えば、超音波探傷試験)の検査性を考慮し、接続部サポート7と8は、溶接部10の検査に必要な距離(例えば、検査装置で溶接部10の超音波探傷試験が可能な距離)だけ離れた位置(Wが2T以上)であれば、例えば、超音波探傷試験を行うには支障がないからである(以下で説明する実施例2及び3も同様である)。 The joint supports 7 and 8 described above are fixed at a position separated by at least 2T or more from the weld 10 between the pipe member 3 of the container 1 and the pipe member 4 of the valve body 2 (a position separated by a distance "W" in FIG. 1). The reason for this is that the joint supports 7 and 8 are connected to the welded portion in consideration of the inspectionability of welding inspection (for example, ultrasonic flaw detection test) after the welding of the tubular member 3 of the container 1 and the tubular member 4 of the valve body 2. 10 (for example, the distance at which the ultrasonic testing of the welded portion 10 can be performed with an inspection device) (W is 2T or more), for example, to perform the ultrasonic testing. This is because there is no problem (the same applies to Examples 2 and 3 described below).

また、本実施例では、接続部サポート7及び8の容器1の管部材3又は弁箱2の管部材4からの高さ(図1に符号“C”で示す)は、容器1の管部材3又は弁箱2の管部材4の外径寸法を“D”とするとD/10以上としている(以下で説明する実施例2及び3も同様である)。 Also, in this embodiment, the height of the joint supports 7 and 8 from the pipe member 3 of the container 1 or the pipe member 4 of the valve box 2 (indicated by symbol “C” in FIG. 1) is 3 or the outer diameter of the pipe member 4 of the valve box 2 is D/10 or more (the same applies to the second and third embodiments described below).

これは、ボルト9による接続部サポート7と8の締結に支障がない接続部サポート7及び8の容器1の管部材3又は弁箱2の管部材4からの高さ“C”は、容器1の管部材3又は弁箱2の管部材4の外径寸法“D”のD/10以上であれば充分であることに基づくものである(以下で説明する実施例2及び3も同様である)。 This is because the height "C" of the joint supports 7 and 8 from the pipe member 3 of the container 1 or the pipe member 4 of the valve box 2 is This is based on the fact that it is sufficient if the outer diameter dimension "D" of the pipe member 3 of the valve body 2 or the pipe member 4 of the valve body 2 is D/10 or more (the same applies to the second and third embodiments described below). ).

また、上記した接続部サポート7と8は、容器1の管部材3と弁箱2の管部材4にボルト穴をあけ、それぞれのボルト穴に接続部サポート7と8を挿入することで、容器1の管部材3と弁箱2の管部材4に固定されている。 Further, the connecting part supports 7 and 8 described above are formed by drilling bolt holes in the pipe member 3 of the container 1 and the pipe member 4 of the valve box 2 and inserting the connecting part supports 7 and 8 into the respective bolt holes. It is fixed to the pipe member 3 of 1 and the pipe member 4 of the valve body 2 .

更に、容器1の管部材3の接続部5と弁箱2の管部材4の接続部6は、全周で、かつ、両者の接続部5、6の外面から内面までが溶接により接続されている。 Furthermore, the connecting portion 5 of the pipe member 3 of the container 1 and the connecting portion 6 of the pipe member 4 of the valve box 2 are connected by welding along the entire circumference and from the outer surface to the inner surface of the connecting portions 5 and 6 of both. there is

しかも、本実施例では、上記の溶接後に接続部サポート7と8が、少なくとも周方向に4箇所以上(本実施例では4箇所)の等角度間隔でボルト9にて接続されている。接続部サポート7と8のボルト9による接続により、接続部5、6の溶接部10に対して軸方向に圧縮応力がかかるため、溶接部10が離れようとする力を緩和でき、接続部5、6の溶接部10の信頼性が向上する。 Moreover, in this embodiment, after the welding described above, the joint supports 7 and 8 are connected by bolts 9 at equal angular intervals of at least four locations (four locations in this embodiment) in the circumferential direction. Since the joint supports 7 and 8 are connected by the bolts 9, compressive stress is applied to the welded portions 10 of the joints 5 and 6 in the axial direction. , 6, the reliability of the welds 10 is improved.

このような本実施例の構成によれば、容器1の管部材3と弁箱2の管部材4の接続部5と6の強度(信頼性)を、溶接と接続部サポート7、8を用いたボルト接続の両方で確保することができ、全周溶接により耐リーク性を確保し、万が一、溶接部10が破断した場合でも、少なくとも4箇所あるボルト9が同時に破断する確率は非常に小さいため、溶接サポート7、8間のボルト接続により、全周破断のリスクを回避することができるため、接続部サポート7と8により溶接部10の熱応力を抑制し溶接部10の接続強度を高めつつ、接続の強度(信頼性)を溶接と接続部サポート7と8の両方で確保し、全周破断防止とフランジ部からの流体リークのリスクを回避できる。 According to the configuration of this embodiment, the strength (reliability) of the joints 5 and 6 of the pipe member 3 of the container 1 and the pipe member 4 of the valve body 2 can be improved by welding and the joint supports 7 and 8. All-around welding ensures leak resistance, and even if the welded portion 10 breaks, the probability that at least four bolts 9 break at the same time is extremely small. , Since the bolt connection between the weld supports 7 and 8 can avoid the risk of all-round breakage, the connection support 7 and 8 suppresses the thermal stress of the weld 10 and increases the connection strength of the weld 10. , the strength (reliability) of the connection can be ensured by both welding and the connection support 7 and 8, preventing breakage around the circumference and avoiding the risk of fluid leakage from the flange.

図2及び図3に、本発明の容器又は配管接続機構の実施例2を示す。 2 and 3 show Example 2 of the container or piping connection mechanism of the present invention.

図2は、本実施例である容器1と弁箱2間の接続機構を示し、図3は、図2の容器1と弁箱2間の接続機構に採用される接続部サポートカバー11を示す。 2 shows the connection mechanism between the container 1 and the valve box 2 of this embodiment, and FIG. 3 shows the connection part support cover 11 employed in the connection mechanism between the container 1 and the valve box 2 in FIG. .

該図に示す本実施例の容器1と弁箱2間の接続機構は、実施例1と略同様な構成であるが、本実施例では、接続部サポート7と8に形成されたはめ込み溝にリングガスケット12をはめ込むと共に、容器1の管部材3の接続部5と弁箱2の管部材4の接続部6は、全周で、かつ、両者の接続部5、6の外面から内面までが溶接により固定され、しかも、本実施例では、容器1の管部材3の接続部5と弁箱2の管部材4の接続部6の溶接後に、接続部サポート7、8を半円盤状の接続部サポートカバー11で挟み、接続部サポート7、8を接続部サポートカバー11で挟んだところで、図3に示すように、ボルト13を用いて半円盤状の接続部サポートカバー11を接続している。 The connection mechanism between the container 1 and the valve box 2 of this embodiment shown in the figure has substantially the same structure as that of the first embodiment, but in this embodiment, the fitting grooves formed in the connection support 7 and 8 The ring gasket 12 is fitted, and the connecting portion 5 of the pipe member 3 of the container 1 and the connecting portion 6 of the pipe member 4 of the valve box 2 are all around and from the outer surface to the inner surface of the connecting portions 5 and 6 of both. It is fixed by welding, and in this embodiment, after welding the connection portion 5 of the pipe member 3 of the container 1 and the connection portion 6 of the pipe member 4 of the valve body 2, the connection portion supports 7 and 8 are connected in a semi-disc shape. When the joint supports 7 and 8 are sandwiched by the joint support cover 11, as shown in FIG. .

ボルト13を用いて半円盤状の接続部サポートカバー11を締め付けることにより、リングガスケット12を面圧で押しつぶすことができ、これにより、耐リーク性が確保できる。 By tightening the semi-disc-shaped connecting part support cover 11 using the bolts 13, the ring gasket 12 can be crushed by surface pressure, thereby ensuring leak resistance.

このような本実施例の構成によれば、実施例1と同様な効果が得られることは勿論、接続部サポート7、8の接続部5、6の溶接部10は、小リークの可能性があるが接続部サポートカバー11及びリングガスケット12により、更なるリーク防止が可能となる。 According to the configuration of this embodiment, the same effects as those of the first embodiment can be obtained, of course, and the welded portion 10 of the connection portions 5 and 6 of the connection portion supports 7 and 8 has the possibility of a small leak. However, the joint support cover 11 and the ring gasket 12 enable further leakage prevention.

なお、上記したはめ込み溝とリングガスケット12は、接続部サポート7、8側に設置しているが、溶接部サポートカバー11側に設置しても同じ効果を得ることができる。 Although the fitting groove and the ring gasket 12 described above are installed on the side of the connection portion supports 7 and 8, the same effect can be obtained even if they are installed on the side of the welded portion support cover 11.
