FLOW DETECTOR USED WITH VACUUM-TYPE SEWAGE COLLECTION SYSTEM, VACUUM-TYPE SEWAGE COLLECTION SYSTEM, DEVICE AND METHOD FOR VACUUM VALVE MONITORING
PROBLEM TO BE SOLVED: To provide a vacuum-type sewage collection system that enables appropriate detection of opening/closing of a vacuum valve inside the vacuum-type sewage collection system, and confirmation on a condition of a detection part, replacement, etc. to be performed readily.SOLUTION: A vacuum-type sewage collection system includes: a sewage suction pipe opening inside a storage tank for storing sewage and having vacuum introduced thereinto for sucking the sewage inside the storage tank; a vacuum valve for opening/closing the sewage suction pipe; an air suction pipe having an end connected to the sewage suction pipe on an upstream side of the vacuum valve and the other end opening above a highest allowable water level of the sewage inside the storage tank; and a flow detector fitted on the air suction pipe and mechanically detecting an air flow into the air suction pipe when the vacuum valve opens.SELECTED DRAWING: Figure 1
【課題】真空式汚水収集システム内における真空弁の開閉を適切に検知することができ、且つ、検知部の状況確認及び交換等を簡便に行うことを可能にする真空式汚水収集システムを提供する。【解決手段】汚水を貯留する貯留槽内に開口し、貯留槽内の汚水を吸引するための真空が導かれる汚水吸引管と、汚水吸引管を開閉する真空弁と、一端が前記真空弁より上流側で汚水吸引管に連通し他端が貯留槽内の汚水の許容最大水位より上方で開口する空気吸引管と、空気吸引管に取り付けられており、真空弁が開くことによって空気吸引管内へ流入する空気の流れを機械的に検知するように構成される、流れ検知装置と、を備える真空式汚水収集システム。【選択図】図１
