CONSTANT WATER LEVEL VALVE DEVICE
To provide a constant water level valve device that prevents a water pressure acting in the constant water level valve device from increasing to a high pressure and stabilizes opening/closing operation of an on/off valve.SOLUTION: A constant water level valve device 10 comprises a body 10A that has an introduction port 11 connected to a pilot pipe, a water discharge port 12 for discharging water sent from the pilot pipe through the introduction port 11, an on-off valve 30 for opening and closing the water discharge port 12, a drive part 15 for driving the on-off valve 30 to an open state/closed state according to a change in a water level in a water storage tank, and a storage part installed between the on-off valve 30 and the introduction port 11 for storing water in the pilot pipe, wherein the body 10A is provided with a relief valve 80 for releasing pressure when water pressure in the storage part exceeds a certain value.SELECTED DRAWING: Figure 2
【課題】定水位弁装置内に作用する水圧が高圧になることを防止し、開閉弁の開閉動作が安定する定水位弁装置を提供する。【解決手段】定水位弁装置１０は、パイロット管と接続される導入口１１と、パイロット管から導入口１１を通じて送られてくる水を排出する吐水口１２と、排出口１２を開閉する開閉弁３０と、貯水槽内の水位の変動に伴って開閉弁３０を開状態／閉状態に駆動する駆動部１５と、開閉弁３０と導入口１１との間に設置され、パイロット管内の水が貯留される貯留部と、を具備する本体１０Ａを有しており、本体１０Ａに、貯留部内の水圧が一定値を超えたときに、その圧力を逃す逃し弁８０を設けたことを特徴とする。【選択図】 図２
