Background technique
As everyone knows, along with the fast development of China's economy, high efficiency pipeline construction, piping method, the various displacements that solve pipeline, the various requirement such as Corrosion of Pipeline that expands with heat and contract with cold, solves that solves pipeline improve constantly flexibly.Therefore, various piping element manufacturer continues to increase the scientific research dynamics that drops into, and is suitable for product that various pipelines connect also in constantly innovation and development.As the modal flexible pipe that various nonmetallic material such as tetrafluoro flexible pipe, plastic-aluminum pipe, rubber pipe are arranged on the market.Though above-mentioned flexible pipe respectively has its advantage, they all have deadly defect separately, and wherein, the material price costliness of tetrafluoro flexible pipe, cost height generally speaking, can only use the environment below 180 degree Celsius; Easy to crack and do not have ductility when the plastic-aluminum canal curvature is big, at high temperature to use, its life-span significantly shortens; And rubber pipe is easily aging, particularly under the high temperature and the environment at open-air sunshine, its life-span significantly shortens, under some particular environment, as the casting machine of steel mill, the cooling system of ladle furnace, because its Environmental Conditions is extremely abominable, the high temperature splashes such as slag that the flexible pipe of nonmetallic material is very likely splashed scald and leak, and cause cooling system failure; Along with being on the increase of introducing equipment, the pipeline of the form that is threaded of its various standards is also more and more, and this also needs the product of piping element manufacturing firm also can tackle flexibly.In addition, because the flange-connection stainless steel metal flexible pipe of at present a lot of manufacturer production all adopts welding manner that flange-connection stainless steel metal flexible pipe is connected with pipe fitting,, be subjected to a lot of restrictions in actual use though the making of this kind structure is simple relatively, in the pipeline of vibrations, the weld bond place is easy to crack and cause revealing; Under some particular environment, the weld bond place is vulnerable to corrosion and reveals; Because cold working and welding without melting heat treated flexible pipe admittedly, in the higher fluid pipeline of chloride ion content, are revealed and very easily produce spot corrosion.In sum, because the existence of above-mentioned defective is badly in need of a kind of Placement simple and flexible, durable pipe connecting element.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of non-welding flange-connection stainless steel metal flexible pipe is provided, and it is applicable to the pipeline that is threaded and forms of various standards, and its ductility is good, and is high temperature resistant, corrosion-resistant, and shock resistance is strong, long service life, and relative cost is low.
The utility model is to realize by following technological scheme: a kind of non-welding flange-connection stainless steel metal flexible pipe, comprise through melting the soft net of cylindrical metal that is woven into by wire of heat treated stainless steel metal bellows and overcoat thereof admittedly, it is characterized in that: the stainless steel metal bellows comprises that crest and trough replace the bellows segment of moulding mutually, two ends of bellows segment have a straight length respectively, this straight length is isometrical with last trough of bellows segment substantially, and be extended formation, inner ring sleeve is contained in this straight length bottom, outside encircling in outer shroud is sleeved on, the end of the soft net of metal embeds in interior ring and the outer shroud, locked fixing by interior ring and the soft net radial direction pressurization of outer hoop, outer shroud outer cover loading nut, inipple and nut screwing clamping.
Suit pad in the described nut.
Being risen to rouse into compacting behind single ripple in described straight length end forms a plane, and this plane is installed on pad in the nut, top suit one sealing gasket on plane.
Described sealing gasket adopts gasket seals such as asbestos, tetrafluoro.
Described stainless steel metal bellows is spirality or Ω shape bellows.
Described stainless steel metal bellows adopts SUS304 or SUS316L stainless steel material.
Described stainless steel metal bellows is latus rectum 15mm, 20mm, 25mm, 32mm, 40mm and 50mm, random lengths.
The soft net of described metal is the soft net of stainless steel metal.
The beneficial effects of the utility model are:
1, owing to the non-welded structure of employing, solved well because the localized heat that welds Stainless Steel Flexible Hose and the generation of stainless steel soft net influences, thereby to the corrosion resistance of product and the adverse effect of vibration strength generation.Therefore, be adapted at using under the vibrations occasion of some typical high frequency low-amplitudes, as: the connection of outlet such as water pump, air compressor.
2, because flange-connection stainless steel metal flexible pipe has passed through after solid melting heat handles, make its metal structure return to the austenitic state before the processing, can improve the anti-corrosion capacity of himself effectively, be particularly suitable for using in the higher occasion of chlorine ion concentration.
3, owing to adopt the Connecting format of union, the thread standard of the inipple that is connected with client's pipeline can be processed into the screw thread of various standards, as: canalis spinalis screw thread made in Great Britain, american standard screw thread etc. are connected with client's pipeline neatly.
4, owing to adopted the mode that is flexible coupling of flange-connection stainless steel metal flexible pipe, allow the on-the-spot pipe arrangement of various pipelines become simply, greatly improved working efficiency.
5, owing to adopt metallic hose, the displacement that can be various device, pipeline absorbs.
