Brief description of the drawings
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model closed condition structural representation;
Fig. 3 is the utility model sealed structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Fig. 1-Fig. 2, the utility model comprises the flange cylinder 1 being fixed on circular pipe water outlet outer wall, described flange cylinder 1 intermediate section is pipeline 1.1, described flange cylinder 1 two ends are flange 1.2, described pipeline 1.1 tops are hinged with flap valve 3 by rotating pin 2, and described flap valve is fixedly connected with slide block 8 on 3 outsides; Described flange cylinder 1 outer upper is fixed with the dunnage 7 perpendicular with flange cylinder 1, and described dunnage 7 is provided with rotating driving device 6, and the output terminal of described rotating driving device 6 is connected with one end of pivoted arm 5, and the other end of described pivoted arm 5 withstands slide block 8.Described pipeline 1.1 tops are fixedly connected with fixed plate 1.3, and described flap valve 3 is hinged on fixed plate 1.3.Described slide block 8 is big top and small bottom wedge shape block structure.
In such scheme, as shown in Figure 3, between described flap valve 3 and flange cylinder 1, be provided with sealing configuration 4.In the side that described sealing configuration 4 contacts with flange cylinder 1 for flap valve 3, protrude from the first protruding ring 4.1 and second protruding ring 4.2 of flap valve 3, between described the first protruding ring 4.1 and the second protruding ring 4.2, be provided with groove 4.3; The outer of described the first protruding ring 4.1 is mutually vertical with described flange cylinder 1; The protruding thickness of described the second protruding ring 4.2 is greater than the thickness of the first protruding ring 4.1, described the second protruding ring 4.12 is to being in tilted layout along the direction of flap valve 3 outers, and the flap valve 3 of the rear end of described the second protruding ring 4.2 is provided with the bending activity space 4.4 for the second protruding ring 4.2.When flap valve 3 is in the time that flange cylinder 1 contacts, the second protruding ring 4.2 can first contact with flange cylinder 1, realizes sealing, and the air in groove 4.3 is extruded, and now can realize super-low voltage sealing.Sealing configuration 4 between flap valve and flange cylinder 1, can realize low pressure (or with no pressure) time, only depends on the deadweight of flap valve just can close sealing, and not needing from gravity of sealing is simultaneously very large, can open damage by water but very low; When high pressure, the sealing configuration of flap valve is in regime of elastic deformation, and meanwhile, the activity space 4.4 bending for the second protruding ring 4.2, can reach under Maximum operating pressure flap valve indeformable can ensure high pressure sealing time.
Working principle of the present utility model: the utility model rotating driving device 6 can drive the rotation of pivoted arm 5, thus realize the regulation of flap valve 3.Wherein, pivoted arm 5 rotates counterclockwise flap valve 3 apertures and increases, and pivoted arm 5 clockwise rotates flap valve 3 apertures and reduces, thereby automatically controls the size of current.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
