のを阻止する。(5) The locking bolt 7 penetrating through the cylindrical wall of the perforated cylindrical portion 10 is made to protrude from the upper end of the upper disc body 36 of the fluid valve 3 to prevent the fluid valve 3 from being pushed back by water pressure. .
(6) 流体弁3と弁挿入装置Kとの係合を解き、次
いで、弁挿入装置Kと作業用制水弁Hを取り外
す。(6) Disengage the fluid valve 3 and the valve insertion device K, and then remove the valve insertion device K and the working water control valve H.
(7) 上蓋2を穿孔筒部1のフランジ13に固定
し、調整金具47を流体弁3の弁棒35の上端
から挿入し、該調整金具47を上蓋2に固定す
る。このとき、流体弁3の弁棒35の芯がずれ
ているとき、調整金具47の調整移動により正
確に芯出しが行われる。(7) Fix the upper lid 2 to the flange 13 of the perforated cylinder part 1, insert the adjusting fitting 47 from the upper end of the valve stem 35 of the fluid valve 3, and fix the adjusting fitting 47 to the upper lid 2. At this time, when the valve stem 35 of the fluid valve 3 is misaligned, the adjusting movement of the adjusting fitting 47 allows accurate centering.
以上の工程により、本装置Sを用いての流体弁
の設置工事は完了する。 Through the above steps, the fluid valve installation work using the present device S is completed.
このように設置された流体弁装置Sにおいて、
弁棒35を回動させていることによりボール30
は90°回転し、全開状態から全閉状態の間を適宜
調整される(通常は全開もしくは全閉状態で使用
される)。この全開状態において、ハウジング3
4の弁穴32A,33Aの開口縁部は既設管Pの
開口に近接しているので、流体は円滑に流れ、こ
の継ぎ目部分で乱流となり流体抵抗を生じること
がない。 In the fluid valve device S installed in this way,
By rotating the valve stem 35, the ball 30
rotates 90 degrees and adjusts between fully open and fully closed as appropriate (usually used in fully open or fully closed state). In this fully open state, the housing 3
Since the opening edges of the valve holes 32A and 33A of No. 4 are close to the opening of the existing pipe P, the fluid flows smoothly and does not become turbulent at this joint portion and cause fluid resistance.
また、ボール30の開閉動作に伴いハウジング
34の反力を受けて回動しようとするが回動止め
38が底部当て板15に係合していることにより
これを良好に阻止する。 In addition, although the ball 30 attempts to rotate due to the reaction force of the housing 34 as the ball 30 opens and closes, the rotation stopper 38 is engaged with the bottom cover plate 15, so that this is effectively prevented.
本考案は上記実施例に限定されるものではな
く、本考案の基本的技術思想の範囲内で種々設計
変更が可能である。すなわち、以下の態様は本考

りなり作用を奏するものであるので、以下の特有
の効果を有する。C. Effects of the Invention The non-water-inserted fluid valve device of the present invention has the above-mentioned configuration and functions, and therefore has the following unique effects.
流体弁はボール弁形式を採るので、仕切り弁
形式のように弁の丈高が高くならず、また、蝶
形弁形式のように開弁時における弁体の水頭損
失を生じずかつ弁体の存在によるクリーニング
時の障害とならない。 Since the fluid valve uses a ball valve type, the height of the valve is not as high as with a gate valve type, and unlike a butterfly valve type, there is no water head loss at the valve body when the valve is opened, and the valve body is Its presence does not cause any obstruction during cleaning.
回り止めは流体弁の挿入操作における芯出し
を行うとともに流体弁の設置後の開閉操作の回
り止めをなし、多様な効果をもつ。 The rotation stopper performs centering during the insertion operation of the fluid valve, and also prevents rotation during the opening/closing operation after the fluid valve is installed, and has various effects.
