In some embodiments, described support has the hatch frame that holds described rocking bar, and described some platforms are provided with recessed below described rocking bar.
Preferably, the free end top of described rocking bar is provided with lining, comprises the just main platform to described lining raised position of a lower surface in described some platforms.
Preferably, the mounting hole of described platform vertically arranges from top to bottom.
In some embodiments, described mounting hole comprises screw, and on described support, corresponding described screw is provided with waist shaped hole.
In some embodiments, described mounting hole comprises the unthreaded hole that penetrates described platform, and on described support, corresponding described unthreaded hole is provided with through hole, and described unthreaded hole and through hole are fixed by bearing pin and cotter pin.
Preferably, described unthreaded hole bottom is provided with the step that can hold described bearing pin afterbody.
The beneficial effect that the utility model is created is:
1, in valve body, all mounting holes have all been avoided, through valve outer surface, therefore can not leaving the passage of seepage;
2, in valve body, establish multiple platforms, support is connected on platform by multiple spot multimode, can realize support and valve body is better located;
3, all mounting holes are vertically beyond mount inlet, and not only convenient processing, also facilitates and install;
4, main platform has flap protective function concurrently, only contacts with lining, prevents that flap from encountering valve interior surface and damaging;
5, bearing pin connection speed is fast, easy for installation.

[embodiment]
As depicted in figs. 1 and 2, the utility model is a kind of single-lobe Swing check valve, comprises valve body 1, support 2, rocking bar 3, lining 4 and flap 5.
Shown in Fig. 1, Fig. 2 and Fig. 3, in valve body 1, there is cavity 11, cavity 11 leads to outside from three outlets, and there are water intake 12 and 13 two outlets of water outlet in cavity below, and cavity 11 top outlets are mount inlet 14.In cavity 11, be provided with three and the integrated platform 15 of valve body 1, wherein two are positioned at water intake 12 both sides, top, in the middle of two platforms 15, have one to be recessed into 16, and another is main platform 151, is positioned at the top of water outlet 13.Main platform 151 middle parts are provided with three screws 152, and screw 152 coordinates double-screw bolt that support 2 is fixed on main platform 151.Main platform 151 both sides are provided with the unthreaded hole 153 that penetrates main platform 151, on the platform 15 that two are positioned at water intake 12 tops, be also provided with the unthreaded hole 153 that penetrates platform 15, unthreaded hole 153 coordinates bearing pin 61 and cotter pin 62 that support 2 is fixed on to platform 15 and main platform 151 tops, and the bottom of above unthreaded hole 154 is all provided with the step 1531 that can hold bearing pin 61 afterbodys.Screw 152 and unthreaded hole 153 are the mounting hole of support 2, and these mounting holes 152,153 do not penetrate valve body 1 outer surface.
Shown in seeing figures.1.and.2, it is the U-shaped member that a side has hatch frame that support 2 is overlooked, and the opening end of support 2 is for holding the rotating shaft of rocking bar 3, and support 2 is provided with the waist shaped hole corresponding with screw 152 21 and through hole 22 corresponding to unthreaded hole 153.Bearing pin 61 passes unthreaded hole 153 and through hole 22 successively from below, then by cotter pin 62, support 2 is tentatively fixing with platform 15 or main platform 151; Double-screw bolt is firmly secured to support 2 main platform 151 through waist shaped hole 21 and screw 152 successively from top.
With reference to Fig. 1, rocking bar 3 is the free end list structure of bending downwards, and the rotating shaft of rocking bar 3 tops is positioned at above water intake 12 after installing, and recessed 16 between platform 15 can hold the switch motion of rocking bar 3.Flap 5 is equipped with in the free-ended below of rocking bar 3, and lining 4 is equipped with in top.When rocking bar 3 free ends decline, flap 5 can be blocked water intake 12; In the time that rocking bar 3 free ends rise, lining 4 can push up main platform 1 lower surface.
In the time that the liquid in valve body 1 flows from water intake 12 to water outlet 13 directions, fluid pressure can be pushed flap 5 open to water outlet 13 directions, flap 5 drives rocking bar 3 free ends to rise, rocking bar 3 is rotated until lining 4 is encountered main platform 151 lower surfaces, cushioning and stoping flap 5 to encounter valve body 1 internal surface affects the effect of damming after playback in case flap 5 is out of shape; When flow rate of liquid reduces while even having mobile round about trend, flap 5 drives rocking bar 4 free ends to decline by self gravitation and by closure of check ring, the liquid side near water outlet 13 at flap 5 of can being dammed.
Above-described is only mode of executions more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
