Abstract
The utility model discloses a steel plant blowing oxygen used metal hose with external flexible protection structures, which comprises a corrugated pipe, a net pipe sleeved outside the outer wall of the corrugated pipe, and connecting pipes fixedly connected with two ends of the corrugated pipe, wherein two ends of the metal wire knitted net pipe are sleeved with sheathes; and the sheathes and the outer walls of the sheathed connecting pipes are fixedly connected. The improvement on the metal hose lies in that the corrugated pipe is arranged on the inner sides at the two ends of the sheathes; two ends of the net pipe is sleeved with the corrugated pipe, the corrugated pipe is fixedly connected with end surfaces of the sheathes, so as to form flexible protection structures. When the metal hose is used, the flexible protection structures and the net pipe as well as the corrugated pipes are twisted together, thereby remarkably reducing the abrasion of the net pipe at ports of the sheathes and remarkably prolonging the service life of the metal hose.
Description
Technical field
The utility model relates to a kind of metallic hose, particularly a kind of steel mill oxygen blast metallic hose.
Background technique
Metallic hose is owing to possess characteristics such as good ductility, high pressure resistant, high-low temperature resistant, corrosion resistance, and it is more high than the life-span of other flexible pipe (rubber, plastic flexible pipe), therefore connects with metallic hose basically during steel mill's oxygen blast now.Mainly by bellows, webmaster, sheath and joint be combined into, length is generally more than 10 meters with metallic hose in steel mill's oxygen blast of prior art.Because steel mill's oxygen blast is longer with metallic hose length, in use, its deflection degree is bigger, metallic hose is deflection continually, after using a period of time, the sheath that is enclosed within the webmaster two ends outward galls the webmaster under the sheath port easily, causes the damaged and inefficacy of metallic hose, changes or keep in repair must consume the production time and increase cost of production.
The model utility content
The utility model provides a kind of simple in structure at the deficiencies in the prior art, can significantly reduce the wearing and tearing of sheath port to webmaster, steel mill's oxygen blast metallic hose of the external flexible protective structure in significant prolongation working life.
The utility model is achieved through the following technical solutions technical goal.
Steel mill's oxygen blast metallic hose of external flexible protective structure, it comprise bellows, outward be enclosed within webmaster on the bellows outer wall, be fixedly connected on the adapter at bellows two ends; The webmaster two ends overcoat sheath of metal wire knitted, and jointly fixedly connected with the adapter outer wall of fit mutually; Its improvements are: be provided with bellows in sheath inboard, two ends, described bellows is enclosed within the webmaster two ends outward, fixedlys connected with the sheath end face, constitutes the flexible protective structure.
In the said structure, the axial length 800～1000mm under the described bellows nature.
The utility model compared with prior art has following good effect:
1. the flexible protective structure is enclosed within the webmaster two ends outward, and is simple in structure, realizes easily.
Metallic hose in use owing to be provided with the flexible protective structure in sheath inboard, two ends, flexible protective structure and webmaster, the common deflection of bellows, thereby significantly reduced the wearing and tearing of sheath port webmaster, significant prolongation the working life of metallic hose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Steel mill's oxygen blast metallic hose of the external flexible protective structure shown in the accompanying drawing 1, it comprise bellows 4, outward be enclosed within webmaster 3 on bellows 4 outer walls, be fixedly connected on the adapter 1 at bellows 4 two ends, the webmaster 3 two ends overcoat sheaths 2 of metal wire knitted, and jointly fixedly connected with adapter 1 outer wall of fit mutually; The utility model is provided with bellows 5 in two ends sheath 2 inboards, is enclosed within webmaster 3 two ends outside the bellows 5, fixedlys connected with sheath 2 end faces, constitutes the flexible protective structure.Present embodiment is steel mill's oxygen blast metallic hose of DN25mm bore, the axial length 1000mm under bellows 5 natures.
The utility model in use owing to be provided with the flexible protective structure in two ends sheath 2 inboards, flexible protective structure and webmaster 3, bellows 4 common deflections, thereby significantly reduced the wearing and tearing of sheath 2 port webmasters 3, significant prolongation the working life of metallic hose.
Claims (2)
