| Zusammenfassung: | To provide a water flow detector that can reliably prevent erroneous handling even with a simple configuration.SOLUTION: In a water flow detector in which a detection box for detecting the opening and closing operation of a check valve body with predetermined detection means is provided in a body with a built-in check valve body, the detection box consists of a base body and a cover. Either the base body or the cover is provided with a cutoff switch that cuts off the output of the detection means. When the base body is covered with the cover at an off position where the cutoff switch cuts off the output of the detection means, at least a part of the cutoff switch interferes with the covering operation so that the cover cannot cover the base body.SELECTED DRAWING: Figure 1
【課題】簡易な構成でありながら誤った取り扱いを確実に防止できる流水検知装置を提供することにある。【解決手段】逆止弁体を内蔵した本体に、逆止弁体の開閉動作を所定の検出手段で検知する検知ボックスを備えた流水検知装置において、検知ボックスは、ベース体とカバーとから成り、ベース体又はカバーの何れかには、検出手段の出力を遮断する遮断スイッチを設けると共に、遮断スイッチが検出手段の出力を遮断するオフ位置で、ベース体にカバーを被蓋する際に、遮断スイッチの少なくとも一部が被蓋動作に干渉してベース体に対してカバーが被蓋できないようにした流水検知装置である。【選択図】 図１ |
