Abstract
The invention is a one-piece type loop metal hose and the assembling method which relate to a metal hose, wherein the hose includes a corrugated pipe, a straight tube, a wire netting case, the straight tube connected with the corrugated pipe is one-piece, the design point is that the straight tube, the wire netting case, the metal grid are one-piece to pass through the loop joint, and exposed on the side of the loop joint in the single flanging. The assembling method is that two sides of the single flanging or the two-side flanging are connected with the corresponding matched loop joint. The invention solves the technical problems of the hose joint connection, and the assembling method is feasible, which has strong applicability, long service life, fast assemble. The invention has the characteristic of high efficiency, low cost, suitable for mass production, which is the ideal matching piece connected between the installed device and the part.
Description
Technical field
The present invention 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 present invention plans to overcome above-mentioned deficiency, and purpose is to provide integral loop metal flexible pipe and assembling method to related domain, makes it can solve the technical problem that hose coupling connects.The objective of the invention is to realize 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.
The assembling method of described integral loop metal flexible pipe, described straight tube, metal net, metal retaining ring are the metal joints that penetrates of integral type, and be single flange and expose a side that is arranged on described metal joint, two sides of metal joint are connected by corresponding supporting metal joint respectively.
The assembling method of described integral loop metal flexible pipe, 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 double-turnup does not have soldering point.The port of described metal net is arranged between single flange and the double-turnup, and two side is connected by corresponding supporting metal joint respectively.
Above-mentioned described straight tube, metal net, metal retaining ring are the metal joints that penetrates of integral type, carry 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 invention solves 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; Assembling method is feasible.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.

Embodiment
The concrete enforcement of the present invention 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 shape equipment 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.
