Abstract
A kind of direct-burried under ground piping that is used for, the pipe coupling of particularly carrying non-normal temperature medium has core and takes over and overlapping socket outer sleeve thereon, packing matcrial between core adapter and outer sleeve overlapping part slit, an end is compressed by retainer ring.This joint is installed on pipeline according to certain method of construction, and wall thickness that can the attenuate pipe is saved ferrous materials in large quantities, and fault-free after can once mounting, need not keep in repair.
Description
Be used for the direct-burried under ground piping, particularly carry the pipe coupling of non-normal temperature medium and the installation method of single compensation.The direct-burried under ground piping is employed now is thick walled tube head and the tail welded seals, and at the certain spacing mounting and fixing bracket.After imbedding soil, stop that by the combination of support and earth the stress that produces is concentrated because pipeline expands with heat and contract with cold, to prevent pipeline breaking.Use the method, need to consume a large amount of ferrous materials, transport volume is big simultaneously, and difficulty is installed, the cost height, and be prone to fault.
The objective of the invention is to innovate a kind of materials and economize, trouble-free pipe coupling of once mounting and corresponding construction method are in order to save ferrous materials.
My structure of " flexible telescopic compensator " utility model patent that is used for above ground piping of acquisition is once transplanted in this invention, and further innovation improves and forming.(" flexible telescopic compensator " patent No.: 882076973) it can guarantee above ground piping because cold and hot distortion and not breaking is not leaked.The structure of direct-burried under ground piping joint has core to take over and the overlapping core that is enclosed within is taken over outside outer sleeve, packing matcrial between the slit of core adapter and outer sleeve overlapping part, and an end is compressed by retainer ring.This joint is welded between the pipeline.Ready back is installed feeds test(ing) medium, after temperature reaches 20%～75% in interval certain of the fed sheet of a media temperature of wanting when a bit, treats that pipeline breathing is stable, after retainer ring compressed and outer sleeve, core adapter girth welding seal.
Fig. 1 is an embodiment of this invention: there is core to take over (1), and sealing material (2), spiral retainer ring (3), outer sleeve (4), connecting tube (5) is formed.Outer sleeve (4) and connecting tube (5) girth welding sealing, packing matcrial (2) is compressed by spiral retainer ring (3) between the slit of outer sleeve (4) and core adapter (1) socket.These joint two ends are sealed with pipeline welding respectively.Its construction method of installation is same as above.
Fig. 2 is another embodiment of this invention: there is core to take over (1), and sealing material (2), spiral retainer ring (3), outer sleeve (4) stops that circle (5) forms.Its construction method of installation is same as above.
This invention has solved the direct-burried underground piping preferably owing to carry the problems such as the caused distortion of non-normal temperature medium, leakage. Use the method for this joint and single compensation can attenuate pipe wall thickness, support reduces, and saves in large quantities ferrous materials, reduces significantly freight volume, and the once mounting success, need not keep in repair.
Claims (6)
1, be used for the direct-burried under ground piping, the pipe coupling of particularly carrying non-normal temperature medium has the core adapter and the overlapping core that is enclosed within is taken over outside outer sleeve, it is characterized in that packing matcrial between core adapter and outer sleeve overlapping part slit, and an end is compressed by retainer ring.
2, be used for the direct-burried under ground piping, particularly carry the installation method of non-normal temperature medium pipeline joint, it is characterized in that after feeding the test(ing) medium temperature in the pipeline when reaching a certain interval value, treating that pipeline breathing is stable, retainer ring is compressed with core take over, outer sleeve is rigidly connected sealing.
3, according to the installation method of the pipe coupling of claim 2, it is characterized in that reaching in 20%～75% interval of wanting the fed sheet of a media temperature certain when some when feeding the test(ing) medium temperature, after treating that pipeline breathing is stable, retainer ring is compressed the back take over girth welding with outer sleeve, core.
4,, it is characterized in that and in the outer ring that core is taken over the end the stop circle of external diameter less than the outer sleeve internal diameter to be set according to the pipe coupling of claim 1.
5,, it is characterized in that retainer ring can adopt screw propulsion to compress according to the pipe coupling of claim 1 or 4.
6,, it is characterized in that in the other end of outer sleeve, to be inserted in connecting tube and girth welding sealing according to the pipe coupling of claim 1.
