THREE-WAY VALVE, PIPING DEVICE, AND, WATER SUPPLY SYSTEM
To provide a three-way valve capable of preventing a valve box passage from being completely closed in at least one valve box passage of the three-way valve, a piping device, and, a water supply system.SOLUTION: The present invention relates to a three-way valve V comprising a valve box A in which a valve box chamber is partitioned, and a valve body B. The valve box A includes: a first valve box port AE1 partitioning a first valve box passage AD1 communicating to the valve box chamber; and a second valve box port AE2 and a third valve box port AE3 respectively partitioning a second valve box passage AD2 and a third valve box passage AD3 which are opposed to each other in a direction orthogonal to a passage axis of the first valve box passage AD1. The valve body B includes: a first opening BF1 communicating to a valve body chamber BC; a second opening BF2 and a third opening BF3 in a direction orthogonal to a center axis of the first opening BF1; and a closing wall BW opposed with the first opening BF1 via the valve body chamber BC. In a state where the closing wall BF of the valve body B is opposed to the second valve box passage AD2, the second valve box passage AD2 and the valve body chamber BC are brought into a mutually communicated state.SELECTED DRAWING: Figure 8
【課題】三方弁の少なくとも１つの弁箱流路において弁箱流路が完全に閉止されるのを防止できる、三方弁、配管装置、及び、給水装置を、提供する。【解決手段】弁箱室を内部に区画する弁箱Ａと、弁体Ｂとを備えた三方弁Ｖであって、弁箱Ａは、弁箱室に連通する第１弁箱流路ＡＤ１を区画する第１弁箱口ＡＥ１と、第１弁箱流路ＡＤ１の流路軸線に直交する方向において互いに対向する第２弁箱流路ＡＤ２及び第３弁箱流路ＡＤ３をそれぞれ区画する第２弁箱口ＡＥ２及び第３弁箱口ＡＥ３とを有し、弁体Ｂは、弁体室ＢＣに連通する第１開口ＢＦ１と、第１開口ＢＦ１の中心軸線に直交する方向の第２開口ＢＦ２及び第３開口ＢＦ３と、弁体室ＢＣを介して第１開口ＢＦ１と対向する閉止壁ＢＷと、を有し、弁体Ｂの閉止壁ＢＷを第２弁箱流路ＡＤ２に対向させた状態において、第２弁箱流路ＡＤ２と弁体室ＢＣとは、互いに連通状態になる。【選択図】図８
