- 内部を一次室と二次室に上下区画する仕切り壁に鉛直方向に開口する通水孔を形成すると共に、前記通水孔の中心軸上の二次室側に軸孔を貫設してなるケーシングと、前記通水孔の二次室側に設けた弁座と、この弁座への着座側先端部を重力方向に直径を漸次縮径した円錐形状に形成すると共に、二次側の後端部に凹陥部を形成し、自重または/および前記後端部に作用する逆方向の水圧によって前記先端部の円錐面の一部を前記弁座に着座可能とする一方、順方向の水圧により前記弁座から離隔して開弁可能とした弁体と、ケーシングの前記軸孔に上下動可能に組み付けられ、二次室内下端には、前記弁体の後端部が当接して当該弁体の弁座からの離隔距離を調整すると共に、前記軸孔の段差と係合して上限位置を規定する円盤部を有する開度調整栓棒とを備え、前記弁体は前記ケーシングの前記軸孔から下方に一体的に突設したガイドリングに前記後端部を挿入したことを特徴とした流量調整弁。
- 開度調整栓棒は、弁体が弁座に着座する全閉位置を起点として上下動可能とした請求項1記載の流量調整弁。
- 開度調整栓棒は、ケーシングの軸孔に螺合すると共に、回転ハンドルを分離可能に備えた請求項1または2記載の流量調整弁。
- 開度調整栓棒は、回転ハンドルをキー結合によって分離可能に備えた請求項3記載の流量調整弁。
- ケーシングに回転ハンドルの回転角度に見合った開度表示部を設けた請求項3または4記載の流量調整弁。
- 開度調整栓棒の二次室内先端に緩衝部を設けた請求項1から5のうち何れか一項記載の流量調整弁。
- 弁体は金属製である請求項1から6のうち何れか一項記載の流量調整弁。
- ケーシングの一次室に通水孔を止水可能なボール型止水栓を一体的に設けた請求項1から7のうち何れか一項記載の流量調整弁。
