VALVE DEVICE FOR FLUID

PROBLEM TO BE SOLVED: To provide a valve device for fluid capable of increasing the amount of fluid emission while a valve plate can be smoothly rotated.SOLUTION: A valve device for fluid 1 comprises: a cylindrical body 11 into which fluid flows; a projection 12 formed on the inside surface 111 of the cylindrical body 11; a valve plate 13 abutting on the projection 12; a bearing member 14 that swingably supports the valve plate 13 so that the outside part of one surface of the valve plate 13 abuts on the projection 12; an engaging member 15 fixed on the other surface of the valve plate 13; and an engaged member 16 fixed on the inside surface 111 of the cylindrical body 11. The engaging member 15 and the engaged member 16 are engaged with each other movably in a direction that the valve plate 13 abutting against the projection 12 separating from the projection 12 and the valve plate 13 remote from the projection 12 is rotatably engaged.SELECTED DRAWING: Figure 2 【課題】弁板を円滑に回動でき、流体の排出量を増大できる流体用弁装置を提供する。【解決手段】流体用弁装置１は、流体が内部に流入される筒状体１１、筒状体１１の内側面１１１に形成された突部１２、突部１２に当接される弁板１３、弁板１３の一方の面の外側部分が突部１２に当接されるように弁板１３を揺動可能に支持する支持部材１４、弁板１３の他方の面に固定された係合部材１５、および、筒状体１１の内側面１１１に固定された被係合部材１６を備える。係合部材１５と被係合部材１６とは、突部１２に当接された弁板１３が突部１２から離れる方向に移動可能に係合され、突部１２から離れた弁板１３が回動可能に係合される。【選択図】図２
