PIPING DEVICE AND WATER SUPPLY DEVICE
To provide a piping device, and a water supply device, which can improve maintenance workability relating to the maintenance of a check valve.SOLUTION: A valve body coupling body LB has a first valve body B1 that is disposed in a first valve box chamber AC1, and divides a first valve body chamber BC1 inside, a second valve body B2 that is located on a second side in a rotation axis direction from the first valve body, is disposed in a second valve body chamber AC2, divides a second valve body chamber BC2 inside, and a bypass pipe 22 that is disposed in a valve box communication chamber AGC, connects the first valve body and the second valve body, and divides a bypass passage 22C communicating the first valve body chamber and the second valve body chamber inside. The first valve box and the first valve body configure a first multi-way valve V1, and the second valve box and the second valve body configure a second multi-way valve V2. A check valve 23 is disposed in the bypass passage, and a valve rod BS has a holding portion BSH detachably holding the check valve.SELECTED DRAWING: Figure 5
【課題】逆止弁のメンテナンスに関わるメンテナンス作業性を向上できる、配管装置、及び、給水装置を提供する。【解決手段】弁体連結体ＬＢは、第１弁箱室ＡＣ１の内部に配置され、第１弁体室ＢＣ１を内部に区画する、第１弁体Ｂ１と、第１弁体よりも回転軸線方向第２側に位置し、第２弁箱室ＡＣ２の内部に配置され、第２弁体室ＢＣ２を内部に区画する、第２弁体Ｂ２と、弁箱連通室ＡＧＣの内部に配置され、第１弁体及び第２弁体どうしを連結し、第１弁体室及び第２弁体室どうしを連通させるバイパス通路２２Ｃを内部に区画する、バイパス管２２と、を有し、第１弁箱及び第１弁体は、第１多方弁Ｖ１を構成しており、第２弁箱及び第２弁体は、第２多方弁Ｖ２を構成しており、逆止弁２３は、バイパス通路の内部に配置されており、弁棒ＢＳは、逆止弁を脱着可能に保持する保持部ＢＳＨを有している。【選択図】図５
