Yes. Further, a piezoelectric element driven metal diaphragm control valve 53a is often used as the flow rate control valve, and the valve opening degree is automatically controlled to adjust to a desired fluid flow rate (special feature). Kaihei 8-338546 etc.).
- FIG. 13 shows an example of the flow rate control valve, that is, a normally closed type piezoelectric element drive type metal diaphragm control valve, which is often used in a flow rate control device of an integrated gas supply device.
- the metal diaphragm control valve includes a valve body 1 having a hole 1a on the upper surface, a metal diaphragm valve body 2, a diaphragm presser 3, a presser adapter 4, a piezoelectric element support cylinder 23 inserted vertically into the hole 1a,

Therefore, the piezoelectric element 10 is supported by a complicated structure, which complicates the support mechanism of the piezoelectric element 10 and makes it difficult to assemble the control valve. This makes it difficult to reduce the manufacturing cost.

Abstract
Description
そして、圧電素子10へ電圧(制御信号)が印加されると、圧電素子10が伸長し、支持筒体23が上方へ押し上げられることにより、開弁状態となる。何故なら、圧電素子10の下端面が、ボール8a及び下部受台9を介して割リベース27上に支持されているため、上端部を圧電素子10の上部へ固定した支持筒体23が、圧電素子10の伸長により皿ばね18の弾性力に抗して上方へ押し上げられ、これにより、押圧されていた金属ダイヤフラム弁体2がその弾性により復元し、弁座からから離れるからである。
しかし、必要とするガス供給ライン数が増加してくると、必然的に集積化ガス供給装置の奥行寸法Lが増加することになり、集積化ガス供給装置が大型化することになる。
何故なら、流量制御装置53には、前記流量制御弁の構造上その奥行寸法(厚み寸法)Loに一定の限界があり,熱式流量制御装置(マスフローコントローラ)の場合でも、圧力式流量制御装置の場合でも、20~25mm以上の厚み寸法Loを必要とするからである。
また、これと同時に、集積化ガス供給装置の大幅な小型化も強く要求されており、例えば、1チャンバマルチプロセス方式に於いては、16種のガス供給ラインを設けた集積化ガス供給装置を横幅W350mm、奥行L250mm、高さH250mm以下の容積スペース内に納めることが、現実に要求されている。
[第1実施形態]
図1乃至図8は本発明の第1実施形態を示すものであり、図1は、本発明の第1実施形態に係るノーマルクローズ型圧電素子駆動式金属ダイヤフラム制御弁の縦断面図、図2は図1のII-II視断面概要図である。
また、当該弁室用孔部1aの底面には弁座6が形成されており、更に、孔部1aの内周面には、後述する押えねじ5をねじ込むための内ねじ1bが形成されている。
尚、図7(a)は当該押えねじ5の平面図及び正面図であり、中央の6角型の孔部5a内へ後述する下部支持筒体22が挿入されている。
即ち、上部支持筒体21の上端部外周面には、位置決めナット12やロックナット13のねじ込み用の外ねじ21cが形成されており、また、その下方部の内周面には、下部支持筒体22をねじ込み固定するために内ねじ21bが形成されている。
尚、上部支持筒体21と下部支持筒体22のねじ込み固定をより確実なものとするために、前記上部支持筒体21の下方内周面の内ねじ21bへ図7(b)に示すよなロック用ねじ26をねじ込み、下部支持筒体22の上端面を押圧固定してねじ連結部をロックするようにしている。尚、26aはロック用ねじ26の外ねじである。
尚、当該下部支持筒体22の上部外周面には、前記上部支持筒体21の下方内周面の内ねじ21bへねじ込み固定するための外ねじ22dが設けられている。また、下部支持筒体22の底壁22cの下方には窪部22bが設けられており、この窪部22bへダイヤフラム押え3が嵌合されている。
圧電素子10へ弁駆動用電圧が入力されることにより、底面がボール9a及び下部受台9を介して支持架台16上に支持された圧電素子10が伸長し、位置決めナット12に連結された上部支持筒体21及びこれに連結した下部支持筒体22が皿バネ18の弾性力に抗して上方へ引き揚げられる。これにより、金属ダイヤフラム弁体2が原形に復元し、開弁される。
図1を参照して、先ず、弁本体1の弁室を形成する弁室用孔部1aの弁座6上に金属ダイヤフラム弁体2を載置し、その外周縁の上方へ押えアダプタ4を挿着し、弁室用孔部1a内へ押えねじ5を締込みして、金属ダイヤフラム弁体2を気密に固定する。
尚、図1において、11はリード線、14はベアリング、15はコネクタ、21aはOリング挿入溝、25はOリングである。
図9乃至図11は、本発明の第2実施形態を示すものである。
当該第2実施形態は、弁本体1上に2基の制御弁を並列に近接して配置する構成としたものであり、2基の制御弁を一体的に組み付けする構造となっている。
また、当該第2実施形態においては、支持筒体23のガイド体24が図11に示すように2連用に形成されており、2つのガイドイ筒24aが連結した状態で形成されている点を除いて、その他の構成は前記第1実施形態の場合と同一である。
また、2基の制御弁を同時に平行して組立できるため、制御弁の組立工数が一基の制御弁の組立の場合と比較して大幅に増加することがなく、高能率でしかも精度の高い組立てを行なうことができる。
