Embodiment one:
As shown in Figure 3, a kind of airtight air-supply pipeline structure of the utility model, comprise: flange 3 and confession airduct 1, described flange 3 is provided with the described air feed pore passed for airduct 1 of one or more confession, described flange 3 is also provided with bolt 2 hole of multiple metal floor 7 for connecting EMU; Described steel pipe and described flange 3 are welded to connect.Namely will be fixed for airduct 1 by flange 3, and then utilize bolt 2 flange 3 and metal floor 7 to be removably connected, both achieved fixing for airduct 1, for convenience detach again, only need take bolt 2 apart during maintenance, directly will be communicated with flange 3 for airduct 1 and change together, change for airduct 1 more for convenience.Flange 3 can also realize sealing function, ensures the air-tightness in motor train unit.
As shown in Fig. 2,6,7, for improving the air-tightness of the junction of the stability of installation further, this airtight air-supply pipeline structure also comprises: packing seal 4 and pressing plate 5, described packing seal 4 and pressing plate 5 are equipped with the air feed pore corresponding with described flange 3 and bolt 2 hole, and namely packing seal 4 is all identical with flange 3 with quantity with the position in bolt 2 hole with the air feed pore on pressing plate 5; Described pressing plate 5 is arranged at the side of described metal floor 7, and described flange 3 is positioned at the opposite side of described metal floor 7, and described packing seal 4 is between described flange 3 and pressing plate 5, and described flange 3 is fastenedly connected by bolt 2 with pressing plate 5.Flange 3 is connected by bolt 2 with pressing plate 5, makes compact siro spinning technology between flange 3, packing seal 4, metal floor 7 and pressing plate 5, ensures the sealing in car and soundproof effect.
Embodiment two:
The present embodiment is substantially identical with embodiment one, and difference is, described packing seal 4 comprises two, and one of them is positioned at the side of described metal floor 7, and another is positioned at the opposite side of described metal floor 7.Be equipped with packing seal 4 in the both sides of metal sheet like this, sealing effectiveness is better.
Embodiment three:
The present embodiment is substantially identical with embodiment one, and difference is, as shown in Fig. 2,3,4,5,8, described packing seal 4 is convex pad, and the middle part of described convex pad is provided with projection, and described air feed pore and bolt 2 hole are all arranged in described projection.Described packing seal 4 and described flange 3 are positioned at the same side of described metal floor 7, and described projection is passed described metal floor 7 and contacted with described pressing plate 5.After arranging like this, the edge clamping of metal floor 7 is between packing seal 4 and pressing plate 5 and be positioned at protruding outside, the protruding toilet waste collector air supply hole through metal floor 7, the raised seals pad 4 of packing seal 4 is stressed more even everywhere, further increases sealing effectiveness and the soundproof effect of junction.
Preferably, described is steel pipe for airduct 1, and described steel pipe is mutually vertical with described flange 3, and the two ends of described steel pipe are equipped with quick coupling 6.Steel pipe welds at air feed pore place with flange 3, and both form a whole, install, dismounting, change all more convenient.Quick coupling 6 can be connected with air feed flexible pipe 9 easily, and connect, dismounting speed is fast, conveniently to install and replacement operation.
Further, described flange 3, packing seal 4 and pressing plate 5 are ellipse, to match with the toilet waste collector air supply hole of metal floor 7, certainly, the area of flange 3, packing seal 4 and pressing plate 5 must be greater than the area of toilet waste collector air supply hole, and projection matches with toilet waste collector air supply hole.
For embodiment three, during installation, first by downward for the projection of packing seal 4, snap in air feed pore, and pressing plate 5 alignment is put into below metal floor 7, will the top being put into packing seal 4 for the flange 3 of airduct 1 be welded with, make for airduct 1 successively through air feed pore corresponding on packing seal 4 and pressing plate 5, then be connected with pressing plate 5 by flange 3 with bolt 2, flange 3, packing seal 4, metal floor 7 and pressing plate 5 are fastenedly connected, and fitting operation completes.
When changing for airduct 1, unclamp bolt 2, take off flange 3 and be communicated with for airduct 1, the flange 3 more renewed and for airduct 1; Certainly, packing seal 4 and pressing plate 5 also can be changed, and replacement operation is simple, installs also easier, can realize Quick overhaul, do not affect the normal operation of vehicle; It is very little that whole airtight air-supply pipeline structure takies interior space; Flange 3 is with integrated for airduct 1, and compact conformation, improves degree of protection, and sound insulating seal is respond well.
As can be seen from the above embodiments, the utility model is connected with the metal floor 7 of vehicle body by adopting the flange 3 removably connected, be welded as a whole for airduct 1 and flange 3, be connected firmly for airduct 1 and vehicle body, convenient disassembly, compact conformation, improve degree of protection, sealing effectiveness is good, and owing to there being flange 3 to exist, its soundproof effect is also relatively good; Packing seal 4 and the setting of pressing plate 5, further increase the tightness of connection and the soundproof effect of junction; Protruding setting, pressurized is more even everywhere to make packing seal 4, connects more firm, air-tightness and soundproof effect better; To be set to steel pipe for airduct 1, and connect act quick coupling 6 at the two ends of steel pipe, and can be connected fast, install with air feed flexible pipe 9, dismantle speed soon, fast and easy is overhauled, and does not affect the normal operation of EMU.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
