Abstract
The invention provides a novel design scheme of a sleeving tee compensator. The sleeving tee compensator comprises an outer pipe (1) of a main pipeline, an insulating layer (2), insulating fixed inner pipe-supporting rollers (3), an inner pipe (4) of the main pipeline, a flexible pipe connector (5), an outer pipe (6) of a branch pipeline, a connecting flange (7) and an inner pipe (8) of the branch pipeline, the insulating layer is arranged between the outer pipe and the inner pipe of the main pipeline, and can effectively inhibit the change of temperature to decrease the thermal expansion and contraction degree of the pipeline, and the insulating fixed inner pipe-supporting rollers are arranged between the outer pipe and the inner pipe of the main pipeline, and not only can reduce the decrease of temperature, but also can prevent damage caused by repetitive friction, so that the service life of the pipeline can be prolonged.
Description
Technical field
The present invention relates to a kind of sleeve pipe threeway compensation device, relate in particular to a kind of sleeve pipe threeway compensation device new design scheme.
Background technique
In remote high pressure steam pipeline conveying technology field, the safe transport saturated vapour exists many insoluble technical barriers at present, and wherein the pipe branch three-way device is the area that security incident the most easily occurs.Because saturated-steam temperature changes greatly, pipeline expands with heat and contract with cold and exceeds safety and bear numerical value, causes the fracture always accidents caused phenomenon of leaking gas in threeway fairlead position to occur repeatedly, to national wealth, brings about great losses.Especially under remote conveying is given condition a present, inner tube axial displacement meeting reaches more than 2-3 times of diameter, can only adopt the method for reinforcing outer tube in the past, and adopt the bulky anchor block of concrete structure fabrication to limit thermal distortion and move and increase slip joint quantity and overcome temperature deformation.Outside the cement anchor block is installed at threeway fairlead device front and back position, increased slip joint at pipe interior and all can increase expense, strengthen engineering cost, and repeatedly the moving of under ground piping, can bring accident potential, and underground soil is caused to negative effect.
Summary of the invention
For solving above technical problem, the invention provides a kind of sleeve pipe threeway compensation device new design scheme, by main pipeline outer tube (1), insulation heat insulation layer (2), the adiabatic fixed support tourelle (3) of inner tube, main pipeline inner tube (4), flexible pipe joint head unit (5), branch pipe(tube) outer tube (6), adpting flange (7), branch pipe(tube) inner tube (8) forms, cover the one layer of heat preservation heat insulation layer between described main pipeline outer tube and main pipeline inner tube, described insulation heat insulation layer can effectively suppress the conversion of temperature, slow down the degree of expanding with heat and contract with cold of pipeline, be provided with the adiabatic fixed support tourelle of inner tube between described main pipeline outer tube and main pipeline inner tube, the adiabatic fixed support tourelle of described inner tube both can reduce the decline of temperature, can avoid again the damage that repeatedly rubs and bring, increase pipeline working life.
The flexible pipe joint head unit is used in the jointing place of described branch pipe(tube) inner tube and main pipeline inner tube, and couples together with adpting flange, and described flexible pipe joint head unit can well be avoided the infringement of expanding with heat and contract with cold and bringing.
Be provided with equally the adiabatic fixed support tourelle of inner tube between described branch pipe(tube) inner tube and branch pipe(tube) outer tube.
Beneficial effect of the present invention is: apparatus of the present invention are safe and reliable, simple, thoroughly stopped the generation of threeway fairlead position fracture gas leakage accident, and do not need pipe strengthening outside need to not increase slip joint at interior conduit yet, greatly reduced engineering cost, improved economic benefit.And the present invention is simple for production, be applicable to mass production.
