Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Of the present utility model this Swing check valve as shown in Figures 1 to 3, it comprises valve body 100, valve gap 200, valve rod 300, valve plate 400, Huan Qi mechanism 500 and controlling mechanism 600.Be provided with intake tunnel 110, exhalant canal 120 and valve pocket 130 in described valve body 100, valve body 100 is compartment shape part, and flowing medium can run through wherein.The sidewall of valve pocket 130 is provided with a rotating shaft 131 rotationally, and the middle part of rotating shaft 131 can be provided with keyway, for connecting valve rod 300.One end of rotating shaft 131 passes from the sidewall of valve pocket 130, for connecting Huan Qi mechanism 500.Described valve gap 200 is fixed on described valve pocket 130, can be provided with sealing gasket 220 between valve gap 200 and valve pocket 130, and bindiny mechanism can be screw rod 210.
This valve plate 400 is fixed on described valve rod 300, and the end of this valve rod 300 is connected to described rotating shaft 131.Under the impact force of flowing medium, valve rod 300 and valve plate 400 can rotate along rotating shaft 131.As Fig. 1, described valve plate 400 has a hanger 410, and described valve rod 300 is fixed on this hanger 410.Because valve rod 300 and hanger 410 are apart from shorter, even if adopt single pinned connection, valve rod 300 still can be fixedly connected with valve plate 400.The diameter of described valve plate 400 is greater than the diameter of described intake tunnel 110, and when valve plate 400 fits intake tunnel 110, valve plate 400 can play and stop reverse media fluid to pass.For improving reverse sealing effect, the end of described intake tunnel 110 is provided with the first seal ring 111, and described valve plate 400 is provided with the second seal ring 420, and described second seal ring 420 is fitted on described first seal ring 111.First seal ring 111 and the second seal ring 420 are tilting structure, and end face is inclined-plane, to ensure that two seal rings have enough surface of contact.
