The ringy baffle plate or the metal baffle strip is welded on the two ends of the metal pipe and firmly connected with the joint of the two ends of the corrugated metal hose, and the metal protection pipe is the corrugated metal pipe whose materials and waveform aren't limited. In the high-temperature working area, the high-temperature resistance fibre can be filled between the metal protection pipe and the metal hose net sleeve. The utility model has the simple structure and the long service life.
Description
Technical field
The utility model relates to a kind of metal tube, particularly a kind of metallic hose of carrying liquid, gas.
Background technique
For carrying liquid or gas, adopt at outer surface has metallic hose net, interior metal bellow for 0.2～0.3 millimeter of wall thickness more at metallurgical works, and two end connectors connect.Because; blast furnace work characteristics institute extremely; the scum that usually has fusion wantonly spatters, and when dropping on metal bellow surperficial in case the high temperature sludge thing that splashes passes the mesh of the metal net that is enclosed within metal bellow outside, is easy to make the surface of the metal bellow of thin-walled to produce fusion hole.In addition: because the steel-making continuous casting machine is operated in the higher environment of 700 °～800 ° temperature, when metal bellow uses in this hot environment, its contained elemental nickel, chromium, titanium etc. form the high temperature corrosion oxidation easily under the condition of high temperature, metal bellow is easy to cracking.Therefore, the deficiency of above-mentioned metal bellow is: working life is short.
The model utility content
The purpose of this utility model provides a kind of long service life, resistant to elevated temperatures metallic hose.
The metallic hose of the utility model conveyance fluid comprises: there is the metal bellow of joint at two ends and at the metallic hose net of the outer surface suit of metal bellow, is with the metal protection pipe of fixedlying connected with joint in the outside of metallic hose net.
The metallic hose of the utility model conveyance fluid, wherein: the metal protection pipe comprises metal tube and the annular plate washer that welds respectively with the two ends of this pipe or the metal shelves bar more than at least 2.
The metallic hose of the utility model conveyance fluid, wherein: the metal protection pipe is a metal bellows.
The metallic hose of the utility model conveyance fluid, wherein: on annular plate washer, have at least 1 air hole.
The metallic hose of the utility model conveyance fluid, wherein: between metal protection pipe and metallic hose net, be filled with high-temperature resistant fiber.
Adopt said structure, owing to be with the metallic hose net in metal bellow outside, the two ends joint of burn-oning is again at metallic hose net outside set metal protecting tube, burn-on annular plate washer or shelves bar and are fixed on the straight tube of two end connector back metal bellow near-ends.Thereby the scum that sputters from blast furnace can directly not dropped on the surface of metal bellow.Owing between metal protection pipe and metallic hose net, be filled with high-temperature resistant fiber, when thereby the metallic hose that makes a kind of conveyance fluid of the present utility model uses in the hot operation zone, its metal bellow that is wrapped in the inside is in the lower environment of temperature, it is oxidized to be that metal bellow is difficult for
Below in conjunction with accompanying drawing the utility model most preferred embodiment is elaborated.
Description of drawings
Fig. 1 is a metallic hose structural representation described in the utility model;
Fig. 2 is the A-A side view of Fig. 1.
Embodiment
Shown in Figure 1, a kind of metallic hose that is used for conveyance fluid described in the utility model, by two ends by the metal bellow 2 of jointing 1, be with metallic hose net 4 at the outer surface of this metal bellow 2, be respectively equipped with the connection protective cap 3 of fixedlying connected at the two ends of this metallic hose net 4 and be with the metal protection pipe 7 of fixedlying connected with outer surface and form with joint 1 at metallic hose net 4 with joint 1.This metal protection pipe 7 can stop that the high temperature sludge thing that blast furnace splashes directly drops on the metal bellow 2, has promptly prolonged the working life of metal bellow 2.This metal protection pipe 7 constitutes by metal tube 6 with for fixing the annular plate washer 8 that this metal tube 6 welds respectively at its two ends, the annular plate washer of metal protection pipe is fixedlyed connected with the joint of metal bellow, or is the metal shelves bar of two ends employing with its welding of fixing metal pipe 6.This metal tube (6) is the metal bellows that material, waveform are not limit.
When being used in the hot operation zone, the above-mentioned metal bellow 2 that is wrapped in metal tube 6 the insides is in the relatively low environment of temperature, metal bellow 2 is difficult for producing high temperature corrosion, can be filled with fiber high temperature resistant, that have heat insulating function between metal tube 6 and metallic hose net 4.
By shown in Figure 2, for the heat that external environment is radiated in the metal tube 6 can in time distribute, the pressure between balance metal tube 6 and the metal bellow 2 have several air holes 9 on annular plate washer 8, and the size shape in hole is not limit.
During manufacturing, it is unrestricted that the internal diameter of the metal protection flexible pipe of a kind of conveyance fluid of the utility model, length, pressure, joint connect form.During use, the metallic hose of a kind of conveyance fluid of the utility model is connected on the equipment of carrying liquid or gas with joint.
Metal tube 6, annular plate washer 8 can overlap into when joint welds, and also can metal tube 6 covers be entered, and annular plate washer 8 is cut to two halves in the joint back after joint weld, and be fixing with metal tube 6 and joint welding again.
Annular plate washer 8 or shelves bar also can localized axial move on the straight tube behind the joint 1.
Claims (6)
1. the metallic hose of a conveyance fluid, comprise: there is the metal bellow (2) of joint (1) at two ends and at the metallic hose net (4) of the outer surface suit of metal bellow (2), it is characterized in that: be with the metal protection pipe (7) of fixedlying connected with joint (1) in the outside of described metallic hose net (4).
