MULTI-WAY VALVE, PIPING DEVICE, AND WATER SUPPLY DEVICE
To provide a multi-way valve in which a dovetail groove is easily formed, a piping device and a water supply device.SOLUTION: A valve body of a multi-way valve comprises a cylindrical valve main body BM, an annular block wall seal member BWS, and an annular block wall lid member BWF. The valve main body BM includes a plurality of openings BF1-BF3 and a block wall main body BWM. The block wall main body BWM includes a block wall base BWMB and a block wall protrusion BWMP. An annular dovetail groove BWA of which the groove width is reduced toward a valve body outer peripheral side is defined between the block wall main body BWM and the block wall lid member BWF, and the block wall seal member BWS is stored in the dovetail groove BWA. The block wall base BWMB includes projected or recessed engage parts BWK in both ends of the block wall base BWMB in a valve body circumferential direction, and the block wall lid member BWF includes recessed or projected engaged parts BWH, which are engaged with the engage parts, in both ends of the block wall lid member BWF in the valve body circumferential direction.SELECTED DRAWING: Figure 7
【課題】アリ溝が形成しやすい、多方弁、配管装置、及び、給水装置を、提供する。【解決手段】多方弁の弁体は円筒型の弁体本体ＢＭと、環状の閉止壁用封止部材ＢＷＳと、環状の閉止壁蓋部材ＢＷＦとを有し、弁体本体ＢＭは複数の開口ＢＦ１～ＢＦ３と、閉止壁本体部ＢＷＭとを有し、閉止壁本体部ＢＷＭは閉止壁ベース部ＢＷＭＢと、閉止壁突出部ＢＷＭＰとを有し、閉止壁本体部ＢＷＭと閉止壁蓋部材ＢＷＦとの間には、弁体外周側に向かうにつれて溝幅が小さくなる環状のアリ溝ＢＷＡが区画されており、アリ溝ＢＷＡ内には、閉止壁用封止部材ＢＷＳが収容されており、閉止壁ベース部ＢＷＭＢは、閉止壁ベース部ＢＷＭＢの弁体周方向の両端部に、凸状又は凹状の係合部ＢＷＫを有しており、閉止壁蓋部材ＢＷＦは、閉止壁蓋部材ＢＷＦの弁体周方向の両端部に、係合部と係合する、凹状又は凸状の被係合部ＢＷＨを有している。【選択図】図７
