Flap, its round structure and size and flange inner diameter match, and described flap top is rotatably connected with flange inner upper end;
Wherein, the circular channel internal diameter in described valve body is greater than internal diameter of the pipeline size.
Preferably, at least 2 Fans installed by wherein said pipeline.
Preferably, the one-way valve quantity of installing in wherein said pipeline is identical with blower fan quantity.
Preferably, wherein said round flanges internal diameter and internal diameter of the pipeline measure-alike.
Preferably, when wherein said blower fan is opened, when gas is greater than the resistance by blower fan by the resistance of one-way valve, closed check valve.
Preferably, when wherein said blower fan cuts out, when gas is less than the resistance by blower fan by the resistance of one-way valve, one-way valve is opened.
Preferably, it also comprises insepction window, and it is gular transparent material, and described insepction window is arranged on valve body one side.
The utility model at least comprises following beneficial effect: 1, in the ventilation duct of induced draft fan access, load one-way valve, solve blower fan random start and stopping problem and cause affect the problem that gas draft reduces, avoid the life-span reducing induced draft fan simultaneously; 2, load insepction window in one-way valve pipeline side, conveniently can observe one-way valve and whether open, check the working state of induced draft fan.
Part is embodied by explanation below by other advantage of the present utility model, target and feature, part also will by research and practice of the present utility model by those skilled in the art is understood.
Accompanying drawing explanation
Fig. 1 is gas pipeline one-way valve structures figure of the present utility model.
One-way valve phase diagram when Fig. 2 is the coupling of multiple stage induced draft fan.
When Fig. 3 is the coupling of multiple stage induced draft fan, the one-way valve phase diagram when is inactive.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
Fig. 1 shows a kind of gas pipeline one-way valve 100 and comprises flange 110, valve body 120, insepction window 130 and flap 140.
Flange 110 is circular metal material flange, and it is made up of central through bore and the flange plate that is connected with through hole; On flange plate, on a certain concentric circle, equal angles lays 10 ~ 15 tapped holes, tapped hole quantity more preferably 12; Described flange 110 symmetry is laid in the two ends of valve body 120, with valve body 120 by integrally welded.
Valve body 120 is the circular metallic conduit of thin-walled, and itself and flange 110 concentric are integrally welded; Wherein, the internal diameter of valve body 120 is large compared with the through hole internal diameter of flange 110, makes valve body 110 be welded on flange plate; Described valve body 120 inner passage is gas distribution channel, and valve body is arranged in the middle part of the gas pipeline of induced draft fan two ends access.
Insepction window 130 is rectangular transparent plastics material, and described insepction window 130 is arranged on valve body 120 by fastening screw trip bolt.
Flap 140 is the circle of metal material, and its round structure size and flange 110 internal diameter match, and flap 140 top and flange 110 inner side surface are by being articulated and connected.
Valve body 120 both sides are connected with 2 flanges 110 by welding, valve body 120 offer insepction window 130, and hinged inside flap 140 and flange 110, wherein the size of flap 140 and flange 110 matches; Flange 110 is connected with gas pipeline 300 by bolt, the both sides of pipeline 300 connect two pipelines of induced draft fan 200, circular channel internal diameter in described valve body 120 is greater than pipeline 300 internal diameter size, the closed conduct 300 when flap 140 vertical drop, when flap is along the rotation of flange 110, pipeline 300 is by gas.
As shown in Figure 2, gas pipeline 300 connects multiple stage induced draft fan 200, induced draft fan 200 gas feeding pipe and outlet pipe access gas pipeline 300 respectively, and one-way valve 100 is arranged on the gas pipeline 300 between gas feeding pipe and outlet pipe, and every Fans 200 correspondence installs an one-way valve 100; When multiple stage blower fan 200 works simultaneously, gas is greater than the resistance by blower fan 200 by the resistance of one-way valve 100, now flap 140 vertical drop closed conduct, and gas cannot pass through one-way valve 100, and passes through from blower fan 200.
As shown in Figure 3, when multiple stage blower fan 200 works simultaneously, wherein 1 Fans quits work suddenly, gas is less than the resistance by blower fan 200 by the resistance of one-way valve 100, now flap 140 is driven the axle of parallel wound orchid 110 to rotate by gas, thus the path that formation gas passes through, whether now gas cannot pass through blower fan 200 place, now observe flap 140 by insepction window 130 and open.
As mentioned above, the utility model at least comprises following beneficial effect: 1, in the ventilation duct of induced draft fan access, load one-way valve, solve blower fan random start and stopping problem and cause affect the problem that gas draft reduces, avoid the life-span reducing induced draft fan simultaneously; 2, load insepction window in one-way valve pipeline side, conveniently can observe one-way valve and whether open, check the working state of induced draft fan.
Although embodiment of the present utility model is open as above, it is not restricted to listed in specification and mode of execution utilization.It can be applied to various applicable field of the present utility model completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
