FLOW PASSAGE OPENING/CLOSING DEVICE
PROBLEM TO BE SOLVED: To provide a flow passage opening/closing device capable of surely supplying refill water even when attached to a flow passage for supplying water to a siphon toilet bowl.SOLUTION: A flash valve SV to be a flow passage opening/closing device performs main cleaning operation for opening a main valve when a multi-step type solenoid valve to be a sub valve provided in a bypass flow passage satisfies a first valve opening amount, and then after the multi-step type solenoid valve is closed to complete the main cleaning operation, the flash valve executes refill water supply operation through the bypass flow passage without opening the main valve when the multi-step type solenoid valve satisfies a second valve opening amount smaller than the first valve opening amount.
【課題】サイフォン便器への水供給流路に取り付けた場合であっても、確実にリフィル水を供給可能な流路開閉装置を提供すること。【解決手段】流路開閉装置であるフラッシュバルブＳＶは、バイパス流路に設けられた副バルブである多段式電磁弁を第１の開弁量とすることで、主バルブを開く主洗浄動作を行い、その後、多段式電磁弁を閉じて主洗浄動作が終了した後、多段式電磁弁を第１の開弁量より小さい第２の開弁量とすることで、主バルブを開くことなく、バイパス流路を通してリフィル水供給動作を実行する。【選択図】 図２
