To stabilize an operation of a check valve, in a joint member having the check valve using a magnetic force.SOLUTION: A joint member 1 attached to drain piping comprises: a joint main body 2 in which a pipe body 100 is connected to an end part thereof; a valve body 41 for opening and closing a drain flow passage of the joint main body 2; a first magnet 42 attached to the valve body 41; a second magnet 43 adsorbed to the first magnet 42; and a spring 44 as a biasing mechanism for biasing the valve body 41 in a valve-closing direction. When drain water is produced from an upstream side with respect to the joint member 1, the valve body 41 is descended, and the check valve 4 is brought into a valve-opening state. At this time, the first magnet 42 and the second magnet 43 separate from each other, and a magnetic force acting between the magnets is attenuated. When drainage from equipment is finished, the valve body 41 is biased upward by the spring 44, the first magnet 42 thereby approximates the second magnet 43, so that the magnetic force acting between the magnets is increased once again, and adsorbed. By this constitution, the joint member 1 can reliably block the drain flow passage.SELECTED DRAWING: Figure 1
【課題】磁力を利用した逆止め弁を備える継手部材において、逆止め弁の作動を安定させることを課題とする。【解決手段】排水配管に取り付けられる継手部材１であって、端部に管体１００が接続される継手本体２と、継手本体２内の排水流路を開閉する弁体４１と、弁体４１に取り付けられた第一磁石４２と、第一磁石４２と吸着する第二磁石４３と、弁体４１を閉弁方向に付勢する付勢機構としてのスプリング４４を備えている。継手部材１に対し、上流側より排水が生じると、弁体４１が下降し、逆止め弁４が開弁状態となる。この時、第一磁石４２と第二磁石４３が離間し、磁石間に働く磁力が減衰する。設備機器からの排水が終了すると、弁体４１はスプリング４４によって上方に付勢されるため、第一磁石４２が第二磁石４３に近接することで、磁石間に働く磁力が再び増加し、吸着する。これにより、継手部材１は内部の排水流路を確実に閉塞することが可能となる。【選択図】図１
