Abstract
The utility model relates to a metal hose, in particular to an oxygen-blown metal hose which is used to connect the converter oxygen lance and the transferring oxygen pipe in the steel making enterprise, comprising a metal bellow whose two ends are provided with straight tube segments, a wire mesh sleeve for coating the metal bellow, loose flanges which are sheathed on the straight tubes of the bellow and seal rings which is welded with the end ports of the straight tubes. The oxygen-blown metal hose is characterized in that the oxygen-blown metal hose also comprises an inner liner winding tube, and the inner liner winding tube is sheathed in the metal bellow and is hermetically connected with the end ports of the straight tube segments of the metal bellow. The honeycomb duct of the utility model is a fine pitch inner liner winding tube with a smooth inner wall, so the pressure loss of fluid and the noise can be reduced. The oxygen-blown metal hose adopts that the loose flanges are connected outwards, which is favorable to avoid that the hose is twisted. Besides, the loose flanges prevent the curvature from being too small in bending. So the utility model has the advantages of good softness, low noise, safety, reliability and durability.
Description
Technical field
The utility model relates to a kind of metallic hose, and especially a kind of steel-making enterprise converter oxygen gun and oxygen blast metallic hose that the oxygen therapy pipeline is connected of being applicable to belongs to oxygen delivery facility technology field.
Background technique
Steelshop in iron and steel enterprise, oxygen lance for steel-making converter and oxygen therapy being connected between the pipeline need be with adapting to the connection flexible pipe that both relative positions change, though the rubber pipe that adopts can satisfy usage requirement at present, the defective that exists has: rubber material is easily aging, working life is short; If tube wall also can take place and break, exists the potential safety hazard of blasting in improper use.In this application, if adopt common metal bellow, high velocity air decreases by having bigger pipeline resistance therein, and produces strong noise.
Summary of the invention
The technical problems to be solved in the utility model is: at the defective that above prior art exists, it is good to propose a kind of torsional resistance, the metallic hose safe and reliable, that noise is low.
In order to solve above technical problem, oxygen blast metallic hose of the present utility model comprises the seal ring that two ends are shaped on the wire sets of the metal bellows of straight length, clad metal bellows, are sleeved on the lap joint flange on the bellows straight tube and weld with the straight tube port, its improvements are: also comprise the liner entwining tube, described liner entwining tube is sleeved in the metal bellows, is connected with the straight length port sealing of metal bellows.
Further improvement of the utility model is; also comprise oversheath; described oversheath is for having bell-mouthed how much surface of revolution housings, and its miner diameter end outwards is sleeved on the bellows straight tube and seam with it, thereby can the connection part of wire sets and metal bellows be played a protective role.
By the said structure analysis as can be known, honeycomb duct of the present utility model is actual to be the level and smooth fine pitch liner entwining tube of inwall, can reduce fluid pressure loss, reduce noise.Adopt lap joint flange to be beneficial to the distortion of avoiding flexible pipe to produce to being externally connected with.In addition, oversheath also has the too small effect of curvature when preventing bending.Therefore, the utlity model has that ductility is good, noise is low, safe and reliable, long-lived advantage.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Embodiment one
The device of present embodiment as shown in Figure 1, oxygen blast metallic hose of the present utility model is made up of metal bellows 2, steel band net 1, liner entwining tube 3, pipe collar 9, oversheath 8, fastening flange 7, lap joint flange 5, seal ring 6 and swing bolt 4.
Metal bellows 2 two ends are shaped on straight length, and liner entwining tube 3 is fine pitch stainless steel flexible pipe, and is isometric with metal bellows 2, and both port sealings connect.Wire sets 1 is coated on the metal bellows 2, pipe collar 9 respectively with the welding of the straight tube at steel band net 1 and bellows 2 two ends, make it reliably to be connected.Oversheath 8 is for having bell-mouthed cylndrical surface housing, and its miner diameter end outwards is set on the straight tube at bellows 2 two ends and seam with it.Fastening flange 7 welds with the port of metal bellows.As required, can make an end and the service of connection devices relative fixed of oxygen blast metallic hose by fastening flange.Suit lap joint flange 5 on the outer end of bellows 2, and seal ring 6 welds with the port of bellows 2.Slip-knot bolt 4 is used to connect lap joint flange 5 to interfacing parts such as converter oxygen gun or oxygen therapy pipelines.
Facts have proved that the utility model can be guaranteed flow, reduce the pressure loss, reduce noise, and can avoid distortion, reliable performance, mounting or dismounting are convenient, long service life.
