Claims (1)
ンプ部と吐出管とを連通する開位置と遮断する閉
位置とに変位自在な弁体が内装され逆止め弁を有
するものにおいて、上記逆止め弁は、上記弁体が
開位置にあるとき閉鎖され閉位置にあるとき上記
吐出管を外部と連通する連通孔を具備することを
特徴とする深井戸用水中ポンプ。 The above-mentioned non-return valve is provided with a valve body interposed between the pump part and the discharge pipe and displaceable between an open position that communicates the pump part and the discharge pipe and a closed position that blocks the communication between the pump part and the discharge pipe. A submersible pump for deep wells, wherein the stop valve is closed when the valve body is in the open position, and has a communication hole that communicates the discharge pipe with the outside when the valve body is in the closed position.
