Abstract
Description
まず図1を参照して、本実施形態におけるバタフライ弁10を備えたプラントの一例としての原子力発電所1の概要について説明する。図1は、本実施形態におけるバタフライ弁10を備えた原子力発電所1の概要図である。
次に、図2及び図3を参照して、バタフライ弁10の詳細な構成について説明する。図2は、本発明の実施形態に係るバタフライ弁10を示す図である。また、図3は、図2のA−A線断面図である。
弁箱11は、金属製の略円筒状の部材であり、内部に流体が流れる流路14が形成されている。弁箱11は、配管7と略同径に形成されている。流路14は、配管7内の流路(図示省略)と連通している。ここで、以下の説明において、流路14の延在方向をX方向と称し、水平な平面においてX方向に直交する方向をY方向と称し、X方向及びY方向に直交する方向をZ方向と称する。
次に、本実施形態のバタフライ弁10の動作について、図3〜図6を参照して説明する。図4〜図6は、本実施形態のバタフライ弁10の動作を説明する図である。また、図4は、弁体12が開放位置にある状態を示す図である。また、図5は、弁体12が回動している状態を示す図である。また、図6は弁体12が最大開放位置にある状態を示す図である。なお、図4〜図6では、弁体12の中央で、且つ、X方向及びY方向に水平な面で断面にしたバタフライ弁10を示している。
図3に示すように、弁体側弁座部18と弁箱側弁座部15が接触し、流路14が遮断されているとき、すなわち弁体12が遮断位置にあるとき、ボス部17の内周面と弁棒13の前進キー22とが接触している。このため、付勢部材からの付勢力による弁体12のB方向への移動は規制される。
図6に示す状態から弁棒13がD方向に回動すると、前進キー22とカム溝23とが係合しているので、弁棒13の回動に伴って、弁体12はD方向に回動する。そして、弁体12が最大開放位置(図6参照)からD方向に回動することで、図5に示すように、流路14の開放量が図6の示す状態に比べて減少する。
本実施形態のバタフライ弁10では、弁体側弁座部18は、膨張黒鉛材の板状体19と、ステンレス剛板20と、を積層させたラミネート構造で形成されている。また、弁箱側弁座部15は、金属製である。このため、弁体側弁座部18及び弁箱側弁座部15のいずれもが、高温、且つ、高放射線環境下における高い耐性を有しているので、高温の流体に晒され、且つ、高放射線環境下に置かれても、劣化変形しない。また、弁体側弁座部を金属で形成する場合に比べ、弁体側弁座部18及び弁箱側弁座部15を密着させることができる。このため、高いシール性能を得ることができる。
したがって、高温の流体に晒され、且つ、高放射線環境下に置かれる場合であっても、バタフライ弁10のシール性能を十分に確保できる(第1の作用)。
したがって、バタフライ弁10のシール性能を長期間確保できる(第2の作用)。
したがって、過酷事故時であっても、バタフライ弁10の操作が可能であり、バタフライ弁10の機能を確保することができる(第3の作用)。
したがって、バタフライ弁10のシール性能を確保するためのメンテナンス作業を比較的容易に行うことができる(第4の作用)。
なお、本発明は上記した実施形態に限定されるものではなく、下記のような様々な変形例が含まれる。上記した実施形態は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。
上記した実施形態では、図2に示すように、駆動部2に遠隔手動操作連結部3介して遠隔手動操作部4を連結する態様を説明した。しかし、これに代えて、図7に示すように、遠隔手動操作連結部3の設置を省略し、遠隔手動操作部4を駆動部2に直接連結してもよい。この場合も、上記した第1の作用、第2の作用及び第4の作用を奏することができる。
また、バタフライ弁10を、図8に示すように、空気圧の調整によって弁体12を駆動させる空気作動駆動部40に連結させてもよい。空気作動駆動部40は、減速機(図示省略)と、減速機に連結しているシリンダ部41と、シリンダ部41と連結している3方電磁弁42と、3方電磁弁42と連結しているポンプ(図示省略)とを有している。
この場合も、上記した第1の作用乃至第4の作用を奏することができる。
また、図9に示すように、遠隔手動操作連結部3の設置を省略し、遠隔手動操作部4を空気作動駆動部40に直接連結してもよい。この場合も、上記した第1の作用、第2の作用及び第4の作用を奏することができる。
また、弁体側弁座部18に代えて金属製の弁体側弁座部を用い、且つ、弁箱側弁座部15に代えて膨張黒鉛材の板状体と、ステンレス剛板と、を積層させたラミネート構造で形成した弁箱側弁座部を用いてもよい。
