Abstract
The utility model discloses a high temperature and high pressure metallic hose, which comprises a connecting tube, a high pressure flange and a corrugated tube, which are respectively connected with both ends of the connecting tube. A metallic net sleeve is wrapped on an outer layer of the corrugated tube and the connecting tube, and the rubber sleeves are mounted on both ends of the corrugated tube and the connecting tube, which are welded into integration. A corrugated body of the corrugated tube is a dense corrugated tube body, and no gaps exist among the corrugations on the corrugated tube. The utility model is capable of enduring the high temperature and high pressure, and the pressure bearing capability enhances 6-8 times compared with a common structure process production. And the utility model improves the permission pressure for the application compared with the same inside nominal diameter metallic hose, which is a comparatively ideal metallic hose in the similar products at present.
Description
Technical field
The utility model relates to a kind of compensation workpiece that is used for the high pressure engineering technology, relates to a kind of High Temperature High Pressure metallic hose specifically.
Background technique
Metallic hose is because of having with the same flexibility of sebific duct, and high temperature resistant, low temperature resistant, ageing-resistant and corrosion resistant performance, and, be widely used in machinery, chemical industry, space flight, shipbuilding and building field as the compensation fitting of length and angle.
At present, existing involved high-pressure metal flexible pipe, as the Chinese patent notification number be among the CN2090650U disclosed a kind of " combined type high-pressure metal hose construction " for the working pressure that solves metallic hose and the diameter square problem that is inversely proportional to of bellows, and many of the little latus rectum metallic hoses that outer wall is with the metal net are provided, be parallel on the cavity of resorption connection mouth in a pair of pressure accumulation chamber, being linked to each other with joint by the epicoele in pressure accumulation chamber constitutes.Though said structure has solved the little deficiency of common Dan Zhida latus rectum metallic hose working pressure,, make its dependable flow constant and increased volume and can not use to the place that the space is restricted because of complex structure.Also some installation unit adopts seamless steel pipe to connect mostly simultaneously, makes it guarantee that pipeline is coaxial; Time-consuming during installation, and can not absorb vibration when connecting with pump or valve and increase dangerous.In addition, picture Jiao Chang is just going up big latus rectum high-pressure rubber pipe (DN65, DN80, DN100) production line by Shenyang the 4th, the maximum withstand voltage 35MPa that reaches, but high temperature resistant the highlyest have only 120 ℃.If high pressure line medium temperature is higher than 120 ℃, pneumatic hose also just can not satisfy.
The model utility content
The purpose of this utility model is for solving the deficiency in the above-mentioned technology, and a kind of metallic hose of High Temperature High Pressure is provided, and by changing the structure shape of bellows interior, makes it have high temperature resistant, high pressure, big latus rectum, usage requirement that working pressure is big.
For achieving the above object, technical solution of the present utility model is achieved like this: a kind of High Temperature High Pressure metallic hose, it is to utilize original metallic hose structure, make bellows wherein encrypt the encryption bellows body form by external pressure, and the ripple on it and ripple be crowded together between crack not with seam.
The technical solution of the utility model also comprises:
The skin of described encryption bellows is provided with two-layer above metal net at least.
Above-mentioned metal net can be the net of Stainless Steel Wire or Stainless Steel Band weaving.
Characteristics and effect that the utility model compared with prior art has are:
1, have high temperature resistantly, medium temperature can reach 900 ℃;
2, high pressure resistant, make bearing capacity than ordinary construction technology and improve 6-8 doubly;
3, corrosion-resistant, encrypt the bellows body and adopt stainless steel SUS304 or SUS316 material, and adapter and flange can select stainless steel village matter for use according to need, further increase decay resistance.
4, simple in structure, the list of comparing original same inside nominal diameter props up metallic hose, and it is big more to have improved inside nominal diameter, and allows the more little problem of working pressure.
Description of drawings
Fig. 1 is this novel topology view.
Fig. 2 is another example structure view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.
By High Temperature High Pressure metallic hose shown in Figure 1, it comprises selects for use one to take over 2, connect high pressure flange 1 respectively and form encryption bellows 4 at its two ends of taking over 2 through external pressure, wherein take over 2 and high pressure flange 1 between be integral by being welded to connect, and encrypting bellows 4 and taking over 2 outer clad metal nets 3, be provided with the cover skin 5 of withholding installation by being positioned at metal net 3 two ends of taking over 2 positions, the longitudinal end of overlapping skin 5 and metal net 3 be fixed by welding in the adapter 2 form one.
In addition, described encryption bellows 4 is crowded together crack not with seam each other between ripple on it and the ripple, thereby the corrugated flexible hose of this structural type both improved working pressure, and what guaranteed again that flexible pipe had is flexible.
The metal net 3 that relates in above-mentioned can adopt the silk footpath of Stainless Steel Wire for more than the 0.5mm, or the tape thickness of Stainless Steel Band is the net of the above braiding of 0.3mm.In view of this metallic hose has the characteristic of High Temperature High Pressure, thereby adopt two-layer above metal net 4 at least.
It is the stainless steel thin-wall bellows of 0.3-0.8mm that encryption bellows in above-mentioned can be selected pipe wall thickness for use.
Fig. 2 has provided another example structure, and it is to have done corresponding change on the architecture basics of Fig. 1, has possessed above-mentioned performance equally.Its improved structural type is to utilize to encrypt the straight length that certain-length is left at bellows 4 two ends, one end of its adapter 2 is inserted in the straight length, equally, at its skin of encrypting bellows 4 metal net 3 is set, and withhold installation sleeve skin 5 thereon, the two ends that make cover skin 5 and metal 3 with take over 2 and be fixed into one by welding.
By above-mentioned exemplary construction, draw according to the inside nominal diameter of different size and the test of working pressure, see Table one, two.
1, encrypt bellows tube wall 0.6mm, two-layer weaving stainless (steel) wire mantle fiber footpath 0.6mm:
| Inside nominal diameter mm | Allow working pressure MPa | Inside nominal diameter mm | Allow working pressure MPa |
| 50 | 30 | 100 | 25 |
| 65 | 30 | 125 | 20 |
| 80 | 25 | 150 | 15 |
2, encrypt bellows wall thickness 0.6mm, the net of the thick 0.5mm weaving of silk footpath 1mm or steel band:
| Inside nominal diameter mm | Allow working pressure MPa | Inside nominal diameter mm | Allow working pressure MPa |
