MULTIFUNCTIONAL DISCHARGE PIPE OR MULTIFUNCTIONAL VALVE AND PUMP FACILITY
PROBLEM TO BE SOLVED: To provide a valve having functions of a check valve and a stopper valve, improving operability or maintainability of a multifunctional valve also having a water-hammer preventing function, eliminating disadvantage caused by a crossing at a right angle between flow-in flow passage and flow-out flow passage and showing less occurrence of cavitation or less loss coefficient.SOLUTION: This invention relates to a multifunctional discharging pipe or a multifunctional valve comprising a flow-in passage having a flow-in port 1 at an upstream side; a flow-out passage having a flow-out port 2 at a downstream side communicating with the flow-in passage; an evacuation passage 3 branched at a middle branching point between the flow-in port 1 and the flow-out port 2; a valve body 5 having a check valve function arranged to move between a valve seat 4 arranged at the branch point and the evacuation passage 3; a valve body 5 having a function of stopper valve for closing between the flow-in port 1 and the flow-out port 2 at the branch point; and a center line of the flow-out passage and a center line of the evacuation passage 3 form an acute angle.SELECTED DRAWING: Figure 1
【課題】逆止弁及び止水弁の機能を備え、ウォーターハンマー防止機能をも備えた多機能弁の、操作性やメンテナンス性を向上し、流入側と流出側の流路が直交していることに起因する不具合を解消し、キャビテーション発生、損失係数の少ない弁を提供する。【解決手段】上流側に流入口１を有する流入路と、流入路に連通する下流側に流出口２を有する流出路と、流入口１と流出口２の中間の分岐点で分岐されてなる退避路３と、分岐点に設けられてなる弁座４と退避路３の間を移動するように配置される逆止弁機能を有する弁体５と、分岐点において流入口１と流出口２との間を閉塞する止水弁の機能を有する弁体５とを備え、流出路の中心線と退避路３の中心線が鋭角をなす多機能吐出管又は多機能バルブ。【選択図】図１
