Abstract
The utility model relates to an axial flexible sleeve comprising an outer pipeline (1) and an inner pipeline (2), wherein the right end of the outer pipeline (1) is connected with the outer part of a flange (3), and a filling (6) is arranged between the inner part of the flange (3) positioned on the right end of the outer pipeline (1) and an outer pipeline vertical plate (5) connected with the inner part of the outer pipeline (1); and the filling (6) comes into contact with the inner pipeline (2), and the left end of the inner pipeline (2) is provided with an inner pipeline vertical plate (4). Due to the adoption of a taper pipe cutting sleeve type structure, the axial flexible sleeve has the advantages of good flexibility and large inner space; due to the adoption of the simple sealing filling, the axial flexible sleeve has long service life and no maintenance; and meanwhile, the axial flexible sleeve has simple structure, low manufacturing cost and convenient installation.
Description
Technical field
The utility model relates to cement and makes the field, in particular for the parts of cement firing system tertiary-air pipe, and a kind of specifically axial stretching cover,
Background technique
At present, set up of the thermal expansion of high-level tertiary-air pipe in the cement firing system, generally adopt outer non-metal expansion joint or the bellows expansion of metal joint of wrapping up in rubber sleeve for extraction duct.The former the outer rubber sleeve of wrapping up in is not only easily aging damaged, and very inconvenience is changed in the high-altitude; The latter brings very big reaction thrust can for the civil engineering support, increases civil engineering cost.And wrap up in the non-metal expansion joint of rubber sleeve and the complex structure of bellows expansion of metal joint outward, manufacture cost is higher.
The model utility content
The purpose of this utility model is to save the shortcoming and defect that in use exists at existing non-metal expansion joint and bellows expansion of metal, and providing a kind of can move axially, the axial stretching cover that the life-span is long.
The purpose of this utility model solves by the following technical programs:
A kind of axial stretching cover, described axial stretching cover comprises Outer Tube and interior conduit, the right-hand member of described Outer Tube links to each other with the outside of flange, in the inside of the flange of Outer Tube right-hand member and be connected between the Outer Tube riser of Outer Tube inside and be provided with packing; Described packing contacts with interior conduit, and the left end of interior conduit is provided with the interior conduit riser.
Described Outer Tube is the Outer Tube of band Taper Pipe, and Outer Tube links to each other by bolt with flange.
The outside of described packing contacts with Outer Tube, and the inside of packing contacts with interior conduit.
Described flange is the supported flange of " L " type.
The utility model has following advantage compared to existing technology:
1, the utility model adopts Taper Pipe FERRULETYPE structure, when guaranteeing that interior media is by area, and the effectively axial displacement of extraction duct; Simultaneously, inside and outside pipeline is capable of expansion and contraction, can not bring any reaction thrust to the civil engineering support.
2, the utility model adopts easy sealing filler, is packed between the inside and outside pipeline, compress by adjustable supported flange, and long service life, non-maintaining.
3, the utility model is simple in structure, and low cost of manufacture is easy for installation.
Description of drawings
Accompanying drawing 1 is a cross-sectional view of the present utility model.
Wherein, 1-Outer Tube; The 2-interior conduit; The 3-flange; 4-interior conduit riser; 5-Outer Tube riser; The 6-packing; The 7-bolt.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in the figure: a kind of axial stretching cover, it comprises Outer Tube 1 and interior conduit 2, the right-hand member of Outer Tube 1 of band Taper Pipe links to each other by bolt 7 with the outside of " L " type flange 3 that has substrate hold-down function, in the inside of the flange 3 of Outer Tube 1 right-hand member and be connected between the Outer Tube riser 5 of Outer Tube 1 inside and be provided with packing 6; The outside of packing 6 contacts with Outer Tube 1, and the inside of packing 6 contacts with interior conduit 2, and the left end of interior conduit 2 is provided with interior conduit riser 4.
During use, Outer Tube 1 and interior conduit 2 are formed the FERRULETYPE structure earlier, at Outer Tube 1 and 2 fillings of interior conduit packing 6, compress with flange 3 again.Outer Tube riser 5 be used for and flange 3 between form a sealing material and fill the chamber, interior conduit riser 4 then is for preventing that the cutting ferrule that Outer Tube 1 and interior conduit 2 are formed from getting loose.During installation, the end flange of its pipeline 2 should link as the inlet and the outside of interior media, can stretch freely between its Outer Tube 1 and the interior conduit 2 during work, so that absorb expanding with heat and contract with cold of external pipe Yin Wendu generation.The utility model is mainly used in cement plant firing system tertiary-air pipe straight section, and it is good to have stretchability, and the inner space is big, and long service life, non-maintaining characteristics.
Claims (4)
1. axial stretching cover, it is characterized in that described axial stretching cover comprises Outer Tube (1) and interior conduit (2), the right-hand member of described Outer Tube (1) links to each other with the outside of flange (3), be positioned at Outer Tube (1) right-hand member flange (3) inside and be connected between the inner Outer Tube riser (5) of Outer Tube (1) and be provided with packing (6); Described packing (6) contacts with interior conduit (2), and the left end of interior conduit (2) is provided with interior conduit riser (4).
