Abstract
The utility model relates to a metal hose, in particular to an integrated loop metal hose, comprising a corrugated tube, a straight tube and a metal net cover, wherein the corrugated tube and the straight tube are connected integrally. The metal hose is characterized in that the straight tube, the metal net cover and a metal protective ring are integrally penetrated through a metal joint, having a single flange exposed at one side surface of the metal joint. The utility model resolves the connection problem of host joints, having high applicability, long service life, fast assembly, high production efficiency, low cost and batch production, thus is an ideal fitting for the installment and connection of devices.
Description
Technical field
The utility model relates to a kind of metallic hose.
Background technique
At present, metallic hose is one of major part that connects between equipment installation, the parts, and it has the advantages that flexibility is good, high temperature resistant, corrosion-resistant, pressure-bearing is higher.Therefore, be able to extensive use in Aero-Space, machine-building, petrochemical industry, electric power, metallurgy, building industry etc.Metallic hose generally is made up of parts such as corrugated stainless steel tubing, net, retaining ring, adapter, weld-ring, joints, and joint comprises inipple and flanged joint, has fixed and loop type.The general employing of existing metallic hose production technology finished bellows, webmaster, the welding of retaining ring one, again with adapter or joint welding.Another kind of Placement is bellows two ends elder generation and takes over and weld, and again net is enclosed within the bellows two ends, with retaining ring net is pressed in to take over upward and welds, and takes over then and takes over and weld.
The mode of production of above-mentioned metallic hose all is could realize by the multiple tracks welding, because welding produces a large amount of heat, the difference of the wall thickness of each part and material in addition, cause welding part change in shape and thermal stress to be concentrated, cause the structure of metallic material to change, reduced the mechanical strength of product.Therefore, existing metallic hose is shorter working life, and the welding process complexity, manufacturing efficiency is low, cost is high, is not suitable for producing in enormous quantities.
The patent No. ZL 200520102168.X that discloses in the Chinese patent literature, July 5 2006 notice of authorization day, model utility title " metallic hose of band net ", though this part patent has proposed new scheme to known like product, but this design for scheme also exists some deficiency, and especially the connection of hose coupling owes desirable.
Summary of the invention
The utility model plans to overcome above-mentioned deficiency, and purpose is to provide integral loop metal flexible pipe to related domain, makes it can solve the technical problem that hose coupling connects.The purpose of this utility model realizes by the following technical solutions.
A kind of integral loop metal flexible pipe, this flexible pipe comprises bellows, straight tube, metal net, the straight tube that bellows connected is an one, its key points in design is that straight tube, metal net, metal retaining ring are the metal joints that penetrates of integral type, and is single flange and exposes a side that is arranged on described metal joint.
Described single flange is at the socket Duan Duanwei soldering point of the straight tube of metal joint one side, metal net, metal retaining ring.Black ellipse as shown in Figure 2 is a soldering point.The position of soldering point is the one connection for the ease of straight tube, metal net, this three of metal retaining ring, plays seal action.
Described single flange or be made as double-turnup promptly is the twice flange, is continuity at the Duan Duan of the straight tube of described metal joint one side, metal net, metal retaining ring, and the port of described metal net is arranged between single flange and the double-turnup.
Above-mentioned described straight tube, metal net, metal retaining ring be the metal joint that penetrates of integral type, carries out single flange or double-turnup again.The wall thickness of described metal retaining ring directly has influence on the mechanical strength of single flange or double-turnup and the tensile strength of metal net.
The utility model has solved the technical problem that hose coupling connects.Change in shape has been eliminated in no butt welding and thermal stress is concentrated, and has improved the mechanical strength of product.Its applicability is stronger, and working life is longer, and assembling is quick.Have the manufacturing efficiency height, cost is low, is fit to the characteristics produced in enormous quantities, be that equipment is installed, connect comparatively desirable auxiliary equipment between the parts.
Description of drawings
Fig. 1 is a structural representation of the present utility model, has confined A among the figure to the position.
Fig. 2 be the A of Fig. 1 to enlarged diagram, this figure also is the local enlarged diagram of single flange.
Fig. 3 also is a structural representation of the present utility model, has confined B among the figure to the position.
Fig. 4 be the B of Fig. 3 to enlarged diagram, this figure is the local enlarged diagram of double-turnup.
Above figure number and title: 1, bellows, 2, straight tube, 3, the metal net, 4, the metal retaining ring, 5, metal joint, 6, single flange, 7, double-turnup.
Embodiment
The concrete enforcement of the utility model is described as follows.As shown in Figures 1 to 4, single flange 6 of integral loop metal flexible pipe roughly is identical with the structure of double-turnup 7, all is to be made of bellows 1, straight tube 2, metal net 3, metal retaining ring 4, metal joint 5.Metal net 3 is enclosed within the external diameter of bellows 1, straight tube 2, and is metal net 3 between straight tube 2 and metal retaining ring 4.Setting is single flange and is double-turnup respectively, penetrates metal joint, is separately positioned on a side of described metal joint.Described single flange and double-turnup all with in be expanded into the shape apparatus processing and be configured as corrugated, thereafter, axially press process is finished and is close to a continuous whole flange sealing surface.The both ends of the surface of integral loop metal flexible pipe are identical structures, only turnup structure are slightly had any different, and all are to match with corresponding metal joint 5, and this metal joint is meant flange or similar auxiliary equipment.
