Abstract
Description
位置検出センサ70は、ケーシング10の本体部11の上部に設けられて貯留空間13に連通し、対象物であるフロート41の位置を検出するものである。位置検出センサ70は、磁気式のセンサを構成している。
弁作動機構40は、フロート41の上昇下降に伴って変位し、弁操作棒36を上下動させて給気弁20および排気弁30を開閉させる。具体的に、液体圧送装置1では、ドレンが貯留空間13に溜まっていない場合、フロート41は貯留空間13の底部に位置する(図1の状態)。この状態において、弁操作棒36は下降しており、給気弁20は閉じられ排気弁30は開いている。そして、蒸気システムでドレンが発生すると、そのドレンは液体流入口14から流入して貯留空間13に溜まる。貯留空間13にドレンが溜まっていくに従って、フロート41は上昇する。なお、貯留空間13ではドレンが溜まっていくにつれて蒸気が気体排出口17から排出される。
