Description
Technical field
The utility model relates to pipe joint field, is specifically related to a kind of fuel tube pipe joint.
Background technique
The fittings body position of existing fuel tube pipe joint generally adopts screw-thread fit, and sealability is poor, and long-time use there will be gas leak phenomenon, is badly in need of improving.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of fuel tube pipe joint, good seal performance.
For achieving the above object, the technical solution of the utility model is: fuel tube pipe joint, comprise first fittings body and the second fittings body of working in coordination and connecting, sealing gasket is provided with between described first fittings body and the second fittings body, described sealing gasket comprises outer right angle pad, interior right angle pad be connected both arc-shaped pad, described first fittings body front end is provided with the outer annulated column of evagination and interior annulated column, described outer annulated column front end is provided with outer right angle pad, described interior annulated column front end is provided with interior right angle pad, described second fittings body front portion is provided with the convex ring body of flange and evagination, the front end of annulated column in described flange abuts, described convex ring body front end is provided with the apical margin of indent, convex ring body front end abuts outer annulated column front end, an end face of sandwiched outer right angle pad between described apical margin and outer annulated column, the anterior outer wall of described outer annulated column and convex ring body is provided with corresponding edge clipping, bolt is worn in described edge clipping.
The length of described outer annulated column is greater than the length of interior annulated column.
Described flange is positioned at convex ring body front portion.
The beneficial effects of the utility model: interior annulated column front inner wall and the second fittings body front end outer wall, right angle pad in sandwiched between interior annulated column front end and flange inner face, outer annulated column front inner wall and apical margin outer wall, sandwiched outer right angle pad between outer annulated column front end and convex ring body front end, overall sealing performance is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the first fittings body 1, outer annulated column 11, interior annulated column 12, second fittings body 2, convex ring body 21, flange 22, apical margin 23, sealing gasket 3, outer right angle pad 31, interior right angle pad 32, edge clipping 4, bolt 5.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, fuel tube pipe joint, comprise first fittings body 1 and second fittings body 2 of working in coordination and connecting, sealing gasket 3 is provided with between described first fittings body 1 and the second fittings body 2, described sealing gasket 3 comprises outer right angle pad 31, interior right angle pad 32 and arc-shaped pad both being connected, described first fittings body 1 front end is provided with outer annulated column 11 and the interior annulated column 12 of evagination, and the length of described outer annulated column 11 is greater than the length of interior annulated column 12.
Described outer annulated column 11 front end is provided with outer right angle pad 31, described interior annulated column 12 front end is provided with interior right angle pad 32, described second fittings body 2 front portion is provided with the convex ring body 21 of flange 22 and evagination, it is anterior that described flange 22 is positioned at convex ring body 21, described flange 22 abuts the front end of interior annulated column 12, described convex ring body 21 front end is provided with the apical margin 23 of indent, convex ring body 21 front end abuts outer annulated column 11 front end, an end face of sandwiched outer right angle pad 31 between described apical margin 23 and outer annulated column 11, the anterior outer wall of described outer annulated column 11 and convex ring body 21 is provided with corresponding edge clipping 4, bolt 5 is worn in described edge clipping 4.
By interior annulated column 12 front inner wall and the second fittings body 2 front end outer wall, right angle pad 32 in sandwiched between interior annulated column 12 front end and flange 22 inner side surface, outer annulated column 11 front inner wall and apical margin 23 outer wall, sandwiched outer right angle pad 31 between outer annulated column 11 front end and convex ring body 21 front end, and connecting the first fittings body 1 and the second fittings body 2 by bolt 5, overall sealing performance is good.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
