Description
Technical field:
The present invention relates to the compensation device technical field of hot fluid pipeline, be specifically related to a kind of novel slip-type expansion joint.
Background technique:,
Slip-type expansion joint claims again tubular type slip joint, it is the compensation device of hot fluid pipeline, being mainly used in rectilinear duct and additionally arranging the axial thermal expansion displacement absorption compensation of rear appearance, is the compensator among a kind of pipeline that is directly installed on the free from corrosion unidirectional or multidirectional fluid of any conveying.Slip-type expansion joint is widely used in the conveyance conduit of the industries such as cities and towns heating, metallurgy, mine, generating, petrochemical industry, building, is applicable to hot water, steam, oily lipid medium, medium engineering pressure≤2.5Mpa, medium temperature-40 ℃～600 ℃.
The slidingsurface of sleeve expansion joint is through special processing, and corrosion resistance and good under the environment such as salt solution, salt solution is higher more than 50 times than Austenitic Stainless Steel.But also there is certain deficiency in current slip-type expansion joint: as less in compensation rate, maintenance is inconvenient, Safety performance is not high, the more high defect of cost, and can not meet people's user demand, and be unfavorable for applying.
Summary of the invention:
The object of this invention is to provide a kind of slip-type expansion joint, it has, and compensation rate is large, easy to maintenance, Safety performance is high, long service life, and using scope is extensive, and engineering cost is lower, has the high value of wide market prospects and research and design.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it comprises telescopic pipe 1, the first supported flange 2, the second supported flange 3, gland 4, Sealing 8, the first back-up ring 9, the second back-up ring 10, main body tube 11 and grommet 12, the outer wall coaxial sleeve of the second half section of telescopic pipe 1 is connected to main body tube 11, and between the outer wall of the front end of main body tube 11 and telescopic pipe 1, be closely socketed with gland 4, the rear side of gland 4 is closely provided with several Sealing 8, the rear side of Sealing 8 is closely provided with the first back-up ring 9, the front end outer wall of gland 4 is closely socketed with the first supported flange 2, the front end outer wall of main body tube 11 is closely socketed with the second supported flange 3, and the first supported flange 2, the second supported flange 3 is by array bolt 5, nut 6 is fixedly connected with plain cushion 7, the rear end outer wall of telescopic pipe 1 is welded with the second back-up ring 10, the rear end inwall of main body tube 11 is welded with grommet 12.
The seal ring of described Sealing 8 for adopting flexible graphite material to make, it is large that it has intensity, friction factor little (0.04～0.10), high temperature resistant, corrosion protection, anti-aging, can guarantee to slide axially, and can guarantee again to manage interior medium and not leak.
Principle of the present invention is: the second back-up ring 10 is welded on the rear end outer wall of telescopic pipe 1, has anti-slip function, has improved the ability that product meets accidental contingencies, and can guarantee network security operation.Meanwhile, the nonelastic power of compensator when work, thrust is little.In the time that Sealing 8 wearing and tearing cause sealing effect to weaken, fastening the first supported flange 2, the second supported flange 3 again, strengthens sealability, also bolt 5 can be unclamped, and takes off gland 4, refills into one deck or two-layer Sealing 8, compresses the rear continuation of gland 4 and uses.
The present invention has that compensation rate is large, easy to maintenance, Safety performance is high, long service life, and using scope is extensive, and engineering cost is lower, has the high value of wide market prospects and research and design.
