Description

【０００１】
【発明の属する技術分野】
この発明は、マニホールド弁構造体に関する。
【０００２】
【従来の技術】
水や薬品等の複数の流体を所定流量で混合して主流体（混合流体）として供給したり、一の流体に複数種の他の流体を適宜切り替えて混入して供給するため、或いは一の流体を複数の場所へ分配して供給するため、図９及び図１０に示すようなマニホールド弁構造体１００が用いられることがある。
【０００３】
前記マニホールド弁構造体１００は、主ブロック体１０１と、複数の弁ブロック体１１１よりなる。前記主ブロック体１０１には、その長手方向に沿う水平方向の貫通主流路１０２が形成されていると共に、主ブロック体１０１の上面から前記貫通主流路１０２に連通する複数の主ブロック側分岐流路１０３が主ブロック体１０１の長手方向に所定間隔で形成されている。また、前記貫通主流路１０２の一端部には、外部流路と接続するための主接続部１０４が流体流出入部として設けられている。さらに、当該主ブロック体１０１においては、その上面から正面又は背面又は側面に貫通する主ブロック側副流路１０５が前記主ブロック体１０１の長手方向に所定間隔で複数形成されている。なお、前記各主ブロック側副流路１０５の一端部（上面以外の面側の端部）には、外部流路と接続するための副接続部１０６が流体流出入部として設けられている。
【０００４】
一方、弁ブロック体１１１は、前記主ブロック体１０１の上面に複数個（図示の例では３個）並設されている。それぞれの弁ブロック体１１１の下部には、前記主ブロック体１０１の各主ブロック側分岐流路１０３及び各主ブロック側副流路１０５と通じる弁ブロック側分岐流路１１２及び弁ブロック側副流路１１３が上下方向や斜め方向等に形成されると共に、前記弁ブロック側分岐流路１１２及び弁ブロック側副流路１１３と通じる弁室１１４が形成され、該弁室１１４には前記弁ブロック側分岐流路１１２を開閉する弁体１２０が進退可能に収容されている。前記弁体１２０は適宜の弁駆動機構１２５により進退するようになっている。図示の例では、前記弁体１２０には公知のダイヤフラム弁体が用いられ、また、該弁体１２０を進退させる弁駆動機構１２５は電磁誘導作用を利用するものからなっている。なお、図示の符号１２１は弁体１２０の開閉用シール部、１２２は弁体１２０の外周取付部、１２６は弁駆動機構１２５の電磁誘導によって進退する可動鉄芯からなって弁体１２０に取り付けられる作動部材、１２７はコイル、１２８は作動部材１２６を前方へ付勢するバネ、１２９は通電部、１３０は固定ブロック、１３１はケースである。
【０００５】
前記構造のマニホールド弁構造体１００においては、前記複数の主ブロック側副流路１０５の副接続部１０６に、適宜の流体を供給する供給装置が外部流路を介して接続される。そして、必要に応じて前記弁ブロック体１１１の弁駆動機構１２５により弁体１２０を作動させて前記弁ブロック側分岐流路１１２が開放されることによって、流体が貫通主流路１０２内に所定量供給される。なお、複数種の流体を切り替えて貫通主流路１０２内に供給する場合には、必要とされる流体に対応する弁ブロック体１１１の弁ブロック側分岐流路１１２を弁体１２０の作動によって開き、必要とされない流体に対応する弁ブロック体１１１の弁ブロック側分岐流路１１２を弁体１２０によって閉じるようにすれば良い。
【０００６】
しかしながら、上記従来のマニホールド弁構造体１００にあっては、ユーザーのニーズに合わせて、供給（混入）する流体の数等に対応できるように、言い換えれば、組み合わせる弁ブロック体１１１の数に合致するように、その都度主ブロック体１０１を設計しなければならず、汎用性に乏しいのみならず、コスト的にも不利であった。また、当該マニホールド弁構造体にあっては、その設置後、供給する流体の数を増減させる必要が生じたときには、組み合わせる弁ブロック体１１１の数に合わせて主ブロック体１０１を新たに設計変更して取り替える必要が生じるので、手間がかかると共に経済的ではなかった。
【０００７】
【発明が解決しようとする課題】
本発明は前記の点に鑑みて提案されたものであって、汎用性に優れると共に、設置後において供給する流体の数等を変更する場合にも簡単かつ迅速に対応でき、しかもコスト的にも有利なマニホールド弁構造体を提供しようとするものである。
【０００８】
【課題を解決するための手段】
すなわち、この発明は、ベース部材（１１）と、バルブボディ本体（２２）の下部から一体的に突出形成され前記ベース部材に固定される取付用固定部（２１）を備え、前記バブルボディ本体の一側には連結凸部（２３）、他側には該連結凸部に対応する連結凹部（２５）を有し、複数個連結して使用できるように構成されたブロック体よりなり、前記連結凸部内に形成された凸部側連結開口（２４）と、前記連結凹部内に形成された凹部側連結開口（２６）と、前記凸部側連結開口と凹部側連結開口を連通する貫通主流路（２７）と、該貫通主流路に連通し弁体（３０）を介して開閉自在に形成された分岐流路（２８）と、該分岐流路と通じ前記弁体を収容する弁室（２９）と、前記弁体を作動させる弁駆動機構（４０）と、先端に副流路接続口（５２）が形成され前記弁室と連通する副流路（５１）を有する副流路接続部（５０）を備えた複数の弁ブロック体（２０Ａ，２０Ｂ，２０Ｃ）と、前記複数の弁ブロック体の一側端部における連結凹部又は連結凸部に、該連結凹部又は連結凸部に対応する連結用凸状部又は連結用凹状部が形成されたフランジ状の取付端部（６１）が係合して連結されて前記貫通主流路と連通される接続流路（６３）を有する主流路接続部材（６０）と、前記複数の弁ブロック体の他側の端部における連結凸部又は連結凹部に、該連結凹部又は連結凸部に対応する連結用凸状部又は連結用凹状部が形成されたフランジ状の取付端部（７２）が係合して連結されて前記貫通主流路の内径に対応した外径を有する封止部（７１）を前記貫通主流路の一端側開口から挿入することによって該貫通主流路を封止する主流路封止部材（７０）と、前記ベース部材への取付部（８１，９１）を有し、前記主流路接続部材及び主流路封止部材をそれぞれ固定するための端部側固定部材（８０，９０）とを含むことを特徴とするマニホールド弁構造体（１０）に係る。
【０００９】
【発明の実施の形態】
以下添付の図面に従ってこの発明を詳細に説明する。
図１はこの発明の一実施例に係るマニホールド弁構造体の一部切り欠き断面を有する正面図、図２は図１の２矢視図、図３は図１の３−３断面図、図４は図１の４−４断面図、図５は同マニホールド弁構造体における各弁ブロック体の連結前の状態を簡略に示す部分斜視図、図６は主流路接続部材及び端部側接続部材用固定部材等を示す部分斜視図、図７は主流路封止部材及び端部側封止部材用固定部材等を示す部分斜視図、図８は同マニホールド弁構造体の主流路封止部材を用いない使用状態を示す正面図である。
【００１０】
図１ないし図４に示すマニホールド弁構造体１０は、この発明の一実施例に係るものであり、ベース部材１１と、複数（図では３個）の弁ブロック体２０Ａ，２０Ｂ，２０Ｃと、主流路接続部材６０と、主流路封止部材７０と、端部側接続部材用固定部材８０と、端部側封止部材用固定部材９０とを含んでいる。このマニホールド弁構造体１０は、複数の流体を所定流量で混合して主流体として供給したり、一の流体に複数種の他の流体を適宜切り替えて混入したり、或いは所定流体を複数の場所へ分配して供給したりするのに使用される。
【００１１】
ベース部材１１は、各部材の取付部となるもので、適宜の大きさの板状体等からなる。なお、当該ベース部材１１の大きさ（平面サイズ、特には弁ブロック体連結方向Ｘの長さ）は、連結する弁ブロック体の数や各弁ブロック体の大きさ等を考慮して定められる。
【００１２】
複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃ（２０）の各々は、互いに同一構造となっており（勿論、場合によっては多少の相違をもたせても良い。）、前記ベース部材１１への取付用固定部２１とバルブボディ本体２２とを備え、複数個連結して使用できるように構成されたブロック体よりなる。実施例では、前記取付用固定部２１は、バルブボディ本体２２の正面２２ａ及び背面２２ｂの下部から一体的に突出形成されたもので構成されている。図示の符号Ｂ１は前記取付用固定部２１をベース部材１１に固定するためのねじ部材等の固定部材、Ｂ２は座金である。
【００１３】
前記バルブボディ本体２２は、図５からより容易に理解されるように、略直方体に形成され、そのバルブボディ本体２２の一側（ここでは左側面）には連結凸部２３、他側（ここでは右側面）には該連結凸部２３に対応する連結凹部２５が設けられている。そして、各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの取付用固定部２１のベース部材１１への取付時には、隣り合う弁ブロック体２０Ａ，２０Ｂ，２０Ｃの前記連結凸部２３と連結凹部２５の係合によって各弁ブロック体２０Ａ，２０Ｂ，２０Ｃが連結される。なお、実施例では、係合する連結凸部２３と連結凹部２５間には、パッキン等のシール部材Ｓ１が介在されている。図示の符号２１ａは前記取付用固定部２１に形成された取付孔である。
【００１４】
また、前記連結凸部２３内には凸部側連結開口２４が、前記連結凹部２５内には凹部側連結開口２６がそれぞれ形成されていると共に、当該バルブボディ本体２２内部には、前記凸部側連結開口２４と凹部側連結開口２６を連通する貫通主流路２７と、該貫通主流路２７にその上方から連通し弁体３０を介して開閉自在に形成された分岐流路２８と、該分岐流路２８と通じ前記弁体３０を進退可能に収容する弁室２９が形成されている。また、前記弁室２９内壁の分岐流路２８の弁室側開口２８ｏ周縁には、突状の弁座２９ａが突設されている。なお、図では、前記貫通主流路２７は水平方向に沿って形成され、前記分岐流路２８は前記貫通主流路２７に直交するように鉛直方向に沿って形成されている。
【００１５】
さらに、当該バルブボディ本体２２の前記連結凸部２３及び連結凹部２５が形成される面（ここでは側面）に直交する面側（ここでは正面側或いは背面側）には、内部に前記弁室２９と連通する副流路５１を有する副流路接続部５０が設けられている。前記副流路５１の先端（弁室２９の反対側の端）には、各種の流体（副流体）をバルブボディ本体２２内に流出入させるための副流路接続口５２が形成され、該副流路接続口５２を介して流体供給或いは排出用の外部流路と接続される。なお、この実施例では、前記副流路５１は、前記貫通主流路２７と分岐流路２８の両方に直交する方向に沿って形成されている。
【００１６】
前記弁体３０として、この実施例では適宜の弁駆動機構４０により進退（ここでは上下動）するダイヤフラム弁体が用いられている。このダイヤフラム弁体３０は、前記弁座２９ａ内側の分岐流路２８の弁室側開口２８ｏを開閉する円形状の開閉用シール部３１と、該開閉用シール部３１外側に形成された薄肉部３２と、該薄肉部３２外側に形成された外周取付部３３と、前記開閉用シール部３１に取り付けられると共に弁駆動機構４０（後述の作動部材４１）に螺着される螺着部３４を有している。そして、当該弁体３０は、前記外周取付部３３によって前記バルブボディ本体２２の弁室２９内に装備されている。なお、前記開閉用シール部３１，薄肉部３２，外周取付部３３はゴム又は各種プラスチックからなり、それらは一体的に形成されている。また、螺着部３４は金属やプラスチックからなり、その先端に設けられた板状部３５が前記開閉用シール部３１に埋設されている。なお、好ましくは、前記板状部３５の表面積（直径）は前記分岐流路２８の弁室側開口２８ｏの開口面積（開口径）より大きくすることによって、弁体３０の開閉用シール部３１が前記分岐流路２８の弁室側開口２８ｏを閉じる際に、前記板状部３５が分岐流路２８の弁室側開口２８ｏ全体を覆うようにするのが良い。そうすれば、弁体３０で分岐流路２８の弁室側開口を確実にシールすることができると共に、弁体３０の負担も軽減されて、耐久性も向上する。なお、図１，４中の符号２９ｂは弁室２９内壁に形成された弁体３０の外周取付部３３が収容される取付凹部である。
【００１７】
前記弁体３０を進退させる弁駆動機構４０は、バルブボディ本体２２上部に設けられる。この実施例における弁駆動機構４０は、電磁誘導作用を利用するもので構成されている。なお、図示の符号４１は弁駆動機構４５の電磁誘導によって進退する可動鉄芯からなって前記弁体３０の螺着部３４に螺着される作動部材、４２はコイル、４３は作動部材４１を前方（図では下方）へ付勢するバネ、４４は通電部、４５は固定ブロック、４６はケースである。
【００１８】
ここで、図１，４に示された状態は、前記分岐流路２８の弁室側開口２８ｏを閉鎖している場合で、作動部材４１がバネ４３の付勢力によって前進して、その先端に取り付けられた弁体３０の開閉用シール部３１が弁室２９内の弁座２９ａに圧接して前記分岐流路２８の弁室側開口２８ｏを閉鎖して、副流路５１からの流体の分岐流路２８への導入、或いは貫通主流路２７からの流体の弁室２９及び副流路５１への導入を遮断している。これに対して、前記分岐流路２８の弁室側開口２８ｏの開放状態では、コイル４２の電磁誘導により作動部材４１がバネ４３の付勢力に抗して後退して、該作動部材４１の先端に取り付けられた弁体３０の開閉用シール部３１が弁室２９内の弁座２９ａから離隔して前記分岐流路２８の弁室側開口２８ｏを開いて、副流路５１からの流体を分岐流路２８へ導入し、或いは貫通主流路２７からの流体を弁室２９及び副流路５１へ導入する。
【００１９】
なお、各弁ブロック体２０Ａ，２０Ｂ，２０Ｃにそれぞれ設けられた各弁駆動機構４０（各弁体３０）は、各弁ブロック体２０Ａ，２０Ｂ，２０Ｃ毎に流体の供給及び供給停止の切り替えや供給量の増減の調整を行えるよう互いに独立して作動できるようにしたり、或いは各弁ブロック体２０Ａ，２０Ｂ，２０Ｃへの各流体の同時供給や交互供給の場合等に対応できるよう各弁駆動機構４０同士を、コンピュータ制御装置等を介して関連させて作動できるようにしても良い。
【００２０】
主流路接続部材６０は、当該マニホールド弁構造体１０における主流体の流出入部として外部接続部を構成するもので、具体的には各副流路５１から供給された複数の流体（副流体）が混合された混合流体（主流体）の外部への排出、或いは外部からの所定流体のマニホールド弁構造体１０内への供給のためのものである。この主流路接続部材６０は、前記複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃの一側端部（最外側に位置する端面）における連結凹部２５又は連結凸部２３に連結される。なお、図示の例では、当該主流路接続部材６０は、右側に配設された弁ブロック体２０Ａの右側面に設けられた連結凹部２５に連結されているが、これに限らず、複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃの最外側に位置する端面に設けられた連結凸部２３（図では左側に配設された弁ブロック体２０Ｃの左側面に設けられた連結凸部２３に相当する。）に連結されるようにしても良い。
【００２１】
図６等からより容易に理解されるように、前記主流路接続部材６０の取付側端部６１には、前記弁ブロック体の連結凹部２５又は連結凸部２３に対応する連結用凸状部又は連結用凹状部（図では連結用凸状部６２）が形成され、この部分が前記弁ブロック体の連結凹部２５又は連結凸部２３と係合して連結されるようになっている。また、図示の例では、係合する弁ブロック体２０Ａの連結凹部２５と主流路接続部材６０の連結用凸状部６２間には、パッキン等のシール部材Ｓ２が介在されている。さらに、前記主流路接続部材６０内部には、前記各弁ブロック体の貫通主流路２７と連通する接続流路６３が形成されている。またさらに、前記接続流路６３の先端側開口（弁ブロック体の反対側開口）は主流路接続口６４となり、該主流路接続口６４を介して流体排出或いは供給用の外部流路と接続される。なお、図示の主流路接続部材６０においては、前記取付側端部６１（但し、連結用凸状部６２を除く。）は、他部より大径のフランジ状に形成されている。
【００２２】
主流路封止部材７０は、前記複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃの他側の端部、つまり前記主流路接続部材６０の反対側端部（最外側に位置する端面）における貫通主流路２７の一端側開口部分を封止する（塞ぐ）ものである。この主流路封止部材７０は、前記複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃの主流路接続部材６０の反対側端部における連結凸部２３又は連結凹部２５に連結される。なお、図示の例では、当該主流路封止部材７０は、左側に配設された弁ブロック体２０Ｃの左側面に設けられた連結凸部２３に連結されているが、これに限定されない。例えば、前記主流路接続部材６０が左側に配設された弁ブロック体２０Ｃの左側面に設けられた連結凸部２３に連結される場合等には、前記主流路封止部材７０は右側に配設された弁ブロック体２０Ｃの右側面に設けられた連結凹部２５に連結されるようにしても良い。
【００２３】
前記主流路封止部材７０は、図７からよりよく理解されるように、前記貫通主流路２７の内径に対応した外径を有する柱状又は筒状の封止部７１を有し、該封止部７１が前記貫通主流路２７の一端側開口から挿入されることによって該貫通主流路２７が封止されるようになっている。また、主流路封止部材７０の取付側端部７２は、前記封止部７１より大径のフランジ状に形成され、その取付側端部７２には、前記弁ブロック体の連結凸部２３又は連結凹部２５に対応する連結用凹状部又は連結用凸状部（図では連結用凹状部７３）が形成され、この部分が前記弁ブロック体の連結凸部２３又は連結凹部２５と係合して連結されるようになっている。なお、図示の例では、係合する弁ブロック体２０Ｃの連結凸部２３と主流路封止部材７０の連結用凹状部７３間には、パッキン等のシール部材Ｓ３が介在されている。
【００２４】
前記主流路接続部材６０及び主流路封止部材７０は、端部側固定部材８０又は９０によって、ベース部材１１に固定されている。前記主流路接続部材６０を固定する端部側接続部材用固定部材８０は、図６から理解されるように、ベース部材１１への板状の取付部８１と、該取付部８１に立設され主流路接続部材６０のフランジ状の取付側端部６１を外側から押さえる押さえ部８５を有している。そして、この端部側接続部材用固定部材８０は、前記主流路接続部材６０の弁ブロック体への取付後、前記押さえ部８５が前記主流路接続部材６０の取付側端部６１の外側面６１ａに当接するように、前記取付部８１を介してベース部材１１に固定される。図示の符号８２は前記取付部８１に形成された取付孔、８３は前記取付部８１をベース部材１１に固定するためのねじ部材等の固定部材、８４は座金、８６は主流路接続部材６０の取付側端部６１より先端側の一般部（小径部）６５を挿通可能とする前記押さえ部８５に形成された切り欠き部である。なお、端部側接続部材用固定部材８０の押さえ部８５は、前記切り欠き部８６を有するものに限らず、例えば、前記主流路接続部材６０の一般部６５の外径寸法よりも大なる間隔（距離）で平行に立設した２本の板状部により押さえ部を構成しても良い。
【００２５】
一方、前記主流路封止部材７０を固定する端部側封止部材用固定部材９０は、図７から理解されるように、ベース部材１１への取付部９１と、該取付部９１に立設され主流路封止部材７０のフランジ状の取付側端部７２を外側から押さえる押さえ部９５を有している。図示の前記取付部９１は、平面視略コ状に形成されている。そして、この端部側封止部材用固定部材９０は、前記主流路封止部材７０の弁ブロック体への取付後、前記押さえ部９５が前記主流路封止部材７０の取付側端部７２の外側面７２ａに当接するように、前記取付部９１を介してベース部材１１に固定される。図示の符号９２は前記取付部９１の対向する２つの片部９１ａ，９１ｂに形成された取付孔、９３は前記取付部９１をベース部材１１に固定するためのねじ部材等の固定部材、９４は座金である。なお、図示の例では、前記端部側封止部材用固定部材９０の取付部９１における対向する２つの片部９１ａ，９１ｂ間の距離は、少なくとも弁ブロック体下部の奥行き寸法（正面から平面までの距離）以上とされ、前記片部９１ａ，９１ｂが弁ブロック体の両外側（正面側及び背面側）に位置するようになっている。これにより主流路封止部材７０の固定に要するスペースの縮小化、ひいてはベース部材１１の縮小化を図ることができる。
【００２６】
次に、上記構造のマニホールド弁構造体１０の作動について説明する。まず、当該マニホールド弁構造体１０を、純水や薬品等の副流体を所定流量で混合して主流体として供給するために用いる場合における作動について述べる。最初に、前記各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの副流路接続口５２からマニホールド弁構造体１０内に入った各流体（副流体）は、前記副流路５１を経て弁室２９を満たす。次いで、各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの各弁体３０が後退（ここでは上昇）し、前記分岐流路２８が開くと、該分岐流路２８を介して所定流量の各流体が前記貫通主流路２７内に供給され、各流体が混合される。そして、その混合流体が主流体として、前記主流路接続部材６０の接続流路６３の主流路接続口６４から流出する。これに対して、前記弁駆動機構４０の電磁誘導により各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの各弁体３０の何れかが前進（ここでは下降）すると、該弁体３０に対応する分岐流路２８が閉じられ、それに対応する流体の貫通主流路２７への供給が停止する。
【００２７】
続いて、所定流体を複数の場所へ分配して供給するために、当該マニホールド弁構造体１０を用いる場合における作動について述べる。最初に、前記主流路接続部材６０の接続流路６３の主流路接続口６４からマニホールド弁構造体１０内に入った流体は、前記貫通主流路２７を満たすと共に、その流体は各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの各分岐流路２８内に流入する。次いで、前記各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの各弁体３０が後退（ここでは上昇）し、前記分岐流路２８の弁室側開口２８ｏが開くと所定流量の流体が前記各弁室２９内及び各副流路５１内に流入し、その後前記各副流路５１の各副流路接続口５２から弁構造体１０外へ流出される。一方、前記弁駆動機構４０の電磁誘導により各弁ブロック体２０Ａ，２０Ｂ，２０Ｃの各弁体３０の何れかが前進（ここでは下降）すると、該弁体３０に対応する分岐流路２８の弁室側開口２８ｏが閉じられ、流体の弁室２９への流入（供給）が停止する。
【００２８】
なお、本発明は、上記実施例に限定されるものではなく、発明の趣旨を逸脱しない範囲において構成の一部を適宜に変更して実施することができる。例えば、上記実施例では、３個の弁ブロック体を連結しているが、２個の弁ブロック体を連結するようにしても良いし、４個以上の弁ブロック体を連結するようにしても良い。すなわち、弁ブロック体の数を適宜選択するだけで、様々なユーザーのニーズ、つまり多種多様な副流体の数（或いは流体を分配供給する作業場所の数）に簡単に対応でき、汎用性に優れる。また、マニホールド弁構造体の設置後、前記副流体の数（或いは流体を分配供給する作業場所の数）を変更する必要が生じても、それに簡単かつ迅速にしかも低コストで対応することができる。
【００２９】
また、上記実施例では、貫通主流路２７の一端側を主流路封止部材７０により封止して使用されているが、これに限定されず、図８に示すように、複数の弁ブロック体２０Ａ，２０Ｂ，２０Ｃの両側端部（最外側に位置する端面）における連結凸部２３及び連結凹部２５の両方に主流路接続部材６０，６０を連結し、貫通主流路２７の両端側を開放して、一方の主流路接続部材６０の主流路接続口６４を混合流体等の主流体の流出口とし、他方の主流路接続部材６０の主流路接続口６４を前記主流体の流入口となるように使用しても良い。すなわち、本発明のマニホールド弁構造体１０は、主流路接続部材６０及び主流路封止部材７０を適宜利用することにより、ユーザーの望む用途に応じた使用態様の選択が可能となる。
【００３０】
【発明の効果】
以上図示し説明したように、本発明に係るマニホールド弁構造体においては、貫通主流路，分岐流路，弁室，弁体，弁駆動機構，副流路等をそれぞれ有する各弁ブロック体は互いに独立して構成されているので、該弁ブロック体を適宜数組み合わせることにより、ユーザーの多種多様なニーズ、つまり弁構造体内部に供給する流体（副流体）の数（或いは流体を分配供給する場所の数）に合致するマニホールド弁構造体を容易に提供でき、極めて汎用性に優れる。また、当該マニホールド弁構造体は、その設置後に内部に供給する流体の数（或いは流体を分配供給する場所の数）を変更する必要が生じても、それに簡単かつ迅速にしかも低コストで対応することができる。
【００３１】
また、外部との接続部となる主流路接続部材及び主流路の一端側を封止する主流路封止部材は、各弁ブロック体同士を連結するために各弁ブロック体に設けられた連結凸部又は連結凹部と連結可能となっており、複数個連結された弁ブロック体の端部における連結に利用されない連結凹部又は連結凸部に前記主流路接続部材又は主流路封止部材が連結されるように構成されている。そのため、連結する各弁ブロック体を互いに同一の構造とすることができ、すなわち一種類の弁ブロック体で済み、コスト及び設計上極めて有利である。さらに、当該マニホールド弁構造体にあっては、前記主流路接続部材及び主流路封止部材は端部側固定部材を介してベース部材にそれぞれ固定されているため、該主流路接続部材及び主流路封止部材が弁ブロック体から抜けたり外れたりするのを防ぐことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a manifold valve structure.
[0002]
[Prior art]
A plurality of fluids such as water and chemicals are mixed at a predetermined flow rate and supplied as a main fluid (mixed fluid), or a plurality of other fluids are appropriately mixed and supplied to one fluid, or one A manifold valve structure 100 as shown in FIGS. 9 and 10 may be used to distribute and supply fluid to a plurality of locations.
[0003]
The manifold valve structure 100 includes a main block body 101 and a plurality of valve block bodies 111. The main block body 101 has a horizontal through main flow path 102 formed along the longitudinal direction thereof, and a plurality of main block side branch flow paths communicating with the through main flow path 102 from the upper surface of the main block body 101. 103 are formed at predetermined intervals in the longitudinal direction of the main block body 101. In addition, a main connection portion 104 for connecting to an external flow channel is provided at one end of the penetrating main flow channel 102 as a fluid inflow / outflow portion. Further, in the main block body 101, a plurality of main block side sub-channels 105 penetrating from the upper surface to the front surface, the back surface, or the side surface are formed at predetermined intervals in the longitudinal direction of the main block body 101. Note that a sub-connecting portion 106 for connecting to an external channel is provided as a fluid inflow / outflow portion at one end portion (end portion on the surface side other than the upper surface) of each main block side sub-flow channel 105.
[0004]
On the other hand, a plurality (three in the illustrated example) of the valve block bodies 111 are arranged in parallel on the upper surface of the main block body 101. Under the respective valve block bodies 111, the valve block side branch flow paths 112 and the valve block side sub flow paths communicating with the main block side branch flow paths 103 and the main block side sub flow paths 105 of the main block body 101 are provided. 113 is formed in a vertical direction, an oblique direction, or the like, and a valve chamber 114 communicating with the valve block side branch flow path 112 and the valve block side sub flow path 113 is formed. A valve body 120 for opening and closing the flow path 112 is accommodated so as to be able to advance and retreat. The valve body 120 is advanced and retracted by an appropriate valve drive mechanism 125. In the illustrated example, a known diaphragm valve element is used for the valve element 120, and the valve drive mechanism 125 for moving the valve element 120 back and forth uses an electromagnetic induction action. The reference numeral 121 shown in the figure is an opening / closing seal portion of the valve body 120, 122 is an outer peripheral mounting portion of the valve body 120, and 126 is a movable iron core that is advanced and retracted by electromagnetic induction of the valve drive mechanism 125 and attached to the valve body 120. An operation member, 127 is a coil, 128 is a spring for urging the operation member 126 forward, 129 is an energizing portion, 130 is a fixed block, and 131 is a case.
[0005]
In the manifold valve structure 100 having the above-described structure, a supply device that supplies an appropriate fluid is connected to the sub-connection portions 106 of the plurality of main block side sub-channels 105 via an external channel. Then, if necessary, the valve drive mechanism 125 of the valve block body 111 operates the valve body 120 to open the valve block side branch flow path 112, thereby supplying a predetermined amount of fluid into the through main flow path 102. Is done. In addition, when switching and supplying a plurality of types of fluids into the penetrating main flow path 102, the valve block side branch flow path 112 of the valve block body 111 corresponding to the required fluid is opened by the operation of the valve body 120, The valve block side branch passage 112 of the valve block body 111 corresponding to the fluid that is not required may be closed by the valve body 120.
[0006]
However, the conventional manifold valve structure 100 matches the number of fluids to be supplied (mixed) according to the user's needs, in other words, matches the number of valve block bodies 111 to be combined. Thus, the main block body 101 must be designed each time, which is not only poor in versatility but also disadvantageous in terms of cost. In addition, in the manifold valve structure, when it is necessary to increase or decrease the number of fluids to be supplied after installation, the main block body 101 is newly redesigned according to the number of valve block bodies 111 to be combined. Therefore, it was necessary to replace it, and it took time and was not economical.
[0007]

【The invention's effect】
As shown and described above, in the manifold valve structure according to the present invention, the valve block bodies each having a through main flow path, a branch flow path, a valve chamber, a valve body, a valve drive mechanism, a sub flow path, etc. Since it is configured independently, various combinations of the valve block bodies can be combined to provide various user needs, that is, the number of fluids (sub-fluids) to be supplied to the inside of the valve structure (or a place to distribute and supply the fluids). The manifold valve structure that matches the number of In addition, the manifold valve structure can easily and quickly cope with the need to change the number of fluids supplied to the interior after installation (or the number of locations where fluids are distributed and supplied). be able to.
[0031]
In addition, the main flow path connecting member that is a connection part to the outside and the main flow path sealing member that seals one end side of the main flow path are connected protrusions provided on the valve block bodies to connect the valve block bodies to each other. The main flow path connecting member or the main flow path sealing member is connected to a connection concave portion or a connection convex portion that is not used for connection at the end of the plurality of connected valve block bodies. It is configured as follows. Therefore, the valve block bodies to be connected can have the same structure, that is, only one type of valve block body is required, which is extremely advantageous in terms of cost and design. Further, in the manifold valve structure, the main flow path connecting member and the main flow path sealing member are respectively fixed to the base member via the end side fixing member. It is possible to prevent the sealing member from coming off or coming off from the valve block body.
