Abstract
Description
前記流路ブロックに形成され断面形状が円形の収容凹部に収容され、底面に第1のポートおよび第2のポートが形成されたバルブボディと、
外周に形成された外ねじ部が前記収容凹部の内周に形成された内ねじ部に螺合することにより、前記バルブボディを前記収容凹部の底部に向けて押圧しつつ当該バルブボディを前記流路ブロックに固定するボンネットナットと、を有し、
前記バルブボディは、前記流路ブロックの収容凹部の内周面部に嵌まる外周面部を有し、前記外周面部には、前記流路ブロックに対する前記バルブボディの中心軸線回りの回転位置を規定する位置決め用の凸部が形成されている。
図1は、本発明の一実施形態に係るバルブ装置1を装着先である流路ブロック30から取り外した状態を示している。図2はバルブ装置1を流路ブロック30に装着した状態の縦断面を示している。図3はバルブ装置1の底面図を示し、図4は流路ブロック30の収容凹部35の上面図である。
突起4は、2つの円環状突起4aおよび円環状突起4bからなり、円環状突起4aと円環状突起4bとは、一部を共用するように形成されている。すなわち、円環状突起4aおよび円環状突起4bの一部が共通の突起部分4cで構成されている。本実施形態においては、突起4は全体として8の字状の外輪郭形状を有するが、これに限定されるわけではない。円環状突起4aおよび円環状突起4bの一部が共通の突起部分4cで構成されることにより、ポート3p1およびポート3p2の距離をより近づけることが可能となり、バルブボディ3の外径を縮小させることができる。
図3に示すように、上記した位置決め用の凸部3aは、バルブボディ3の底面視において、ボンネットナット20の外周の外ねじ部20aの外径内に収まっている。
また、ポート31pとポート32pの周囲には。収容凹部35の底面35bから突出して形成されたシール用の突起33が流路ブロック30に一体に形成されている。突起33は、ガスケット21に押し付けられて、ガスケット21を塑性変形させるために設けられている。
突起33は、2つの円環状突起33aおよび円環状突起33bからなり、円環状突起33aと円環状突起33bとは、一部を共用するように形成されている。すなわち、円環状突起33aおよび円環状突起33bの一部が共通の突起部分33cで構成されている。突起33は、バルブボディ3の突起4に対応する位置に形成されている。
さらに、収容凹部35の内周には、軸線Ctに平行に上端部から底部に向けて延びる溝部35cが形成されている。溝部35cにバルブボディ3の凸部3aが係合し、流路ブロック30に対するバルブボディ3の軸線Ct回りの回転位置が規定される。溝部35cにバルブボディ3の凸部3aが係合することで、流路ブロック30のポート31pおよびポート32pに、バルブボディ3のポート3p1およびポート3p2がそれぞれ位置合わせされる。なお、図2から分かるように、溝部35cは、内ねじ部35sの谷径の内側に形成されている。
突起4および突起33は、仮想平面PLに関して左右対称に形成されているので、突起4および突起33に作用する力は均等化され、シール性が安定化される。
さらに本実施形態によれば、シール用の突起4および突起33を2つの円環状突起の一部が共通の突起部分で構成されている構成としたので、ポート間の距離を短縮化でき、バルブボディの外径を縮小させることができる。この結果、収容凹部35の内径も小さくできるので、さらに小型化、集積化に適したバルブ装置が提供される。
ボンネットナット20を操作できる範囲で、バルブ装置1の間を接近させることができるのが分かる。
図6に示すシステムは、半導体製造プロセス等を実行するガス供給システムであり、200はガス供給源、210は手動弁、220は減圧弁、230は圧力計、240はフィルタ、250は自動弁、260はチャンバを示している。
このシステムにおいては、ガス供給源200から供給された処理ガスは、手動弁210、減圧弁220、圧力計230、フィルタ240、自動弁250等の複数の流体機器により制御される。本実施形態のバルブ装置1は、ユースポイント(供給先)であるチャンバ260の直近、すなわち、ガス供給システムの供給経路の最終段に設けられ、これを開閉制御することで、複数の流体機器より制御された処理ガスをチャンバ260へ供給する。
ここで、「流体機器」とは、流体の流れを制御する機器であって、流体流路を確定するボディを備え、このボディの表面で開口する少なくとも2つの流路口を有する機器である。具体的には、開閉弁(手動弁、自動弁)、レギュレータ、圧力計、フィルタ等が含まれるが、これらに限定されるわけではない。
上記実施形態では、凸部3aをバルブボディ3に形成し溝部35cを流路ブロック30の収容凹部35に形成したが、凸部を流路ブロックの収容凹部の内周面部に形成し、溝部をバルブボディの拡径部に形成しても良い。
