Abstract
The utility model provides a steam direct buried pipe compensator leakage remedy device which comprises a core pipe arranged in an outer protection pipe. The remedy device is sleeved at one end, where a gap is formed between a protection cover and the core pipe, of the core pipe in a concentric mode. The remedy device sequentially comprises the protection cover and a bellow from outside to inside, wherein one end of the protection cover and one end of the bellow are in sealing connection with the protection cover, and the gap is formed between the other end of the protection cover and the core pipe. A steam exhaust pipe is communicated with the bellow, and the steam exhaust pipe outwards penetrates through holes arranged in the protection cover and the outer protection pipe. The steam direct buried pipe compensator leakage remedy device has the advantages of preventing steam in a damaged compensator from shocking and damaging a thermal insulation layer, preventing leaked steam condensate water from soaking thermal insulation cotton, preventing steam leaked from the compensator from accumulating in the outer protection pipe to shorten service life of a pipeline, guaranteeing normal extension, contraction and deformation of the core pipe, bringing convenience to targeted maintenance, reducing overhaul time and reducing earthwork excavated volume.
Description
Technical field
The utility model relates to steam gas pipeline technical field, is specifically related to a kind of insulated steam pipe compensator leakage and remedies device.
Background technique
In the heat distribution pipeline delivering vapor processes such as insulated steam pipe, tend to cause expanding with heat and contract with cold of pipeline due to the variation of vapor (steam) temperature, cause pipeline that dilatation occurs therefrom.Therefore in prior art, mostly by compensation device being set between pipeline with the compensation pipe deforming.
At present, the compensation device that various ways is arranged on market, wherein the bellow type compensation device uses comparatively extensive, but no matter be that any compensation device all exists a common problem: because the frequent operation of compensation device very easily is damaged, after compensation device damages, high temperature and high pressure steam breaks through core pipe thermal insulation layer, then from the observation tube of pillar go out.After the steam immersion that thermal insulation layer is rushed out, will permanently lose heat insulation effect.If the pillar inner accumulated is more outside for high temperature and high pressure steam, its high temperature will cause the fiber glass resin melting of outer pillar outer surface parcel, and makes outer pillar lose the anti-corrosion function.
Because compensation device is embedded in undergroundly with heat distribution pipeline, the maintenance workmen can't determine that it damages position, therefore can't implement to construct targetedly, can only develop as one pleases.From the foregoing, compensation device not only affects the appearance of the city after damaging, and what is more important has been wasted a large amount of energy, resource.Cause unnecessary loss to society and enterprise.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of insulated steam pipe compensator to leak and has remedied device, after compensation device damages, can drain earthward steam and water by this device, can accurately judge leakage point, be convenient to safeguard, avoid destroying the anticorrosive coat of thermal insulation layer, outer pillar simultaneously.
The utility model is achieved through the following technical solutions:
The insulated steam pipe compensator leaks remedies device, comprise the core pipe be arranged in outer pillar, and be sheathed on the compensator on the core pipe, be provided with the A gap between protecting cover one end of described compensator and core pipe, at protecting cover and core pipe, be provided with on the core pipe of this end in A gap, concentric is arranged with remedies device, described A gap with remedy device and be communicated with, the described device of remedying is provided with exhaust steam pipe.
The further improvement of the utility model scheme is: the described device of remedying comprises and is provided with successively from outside to inside protective housing, bellows, the same end of described protective housing, bellows is sealedly attached to protecting cover, the other end of bellows is sealedly attached to the core pipe, between the other end of protective housing and core pipe, is provided with the B gap.
The further improvement of the utility model scheme is: the position that is tightly connected of described bellows one end and compensator is positioned at the periphery, A gap of protecting cover and core pipe.
The further improvement of the utility model scheme is: the described device of remedying comprises protective housing, the bellows set gradually from outside to inside, and described exhaust steam pipe is communicated in bellows, and exhaust steam pipe outwards passes protective housing, the set hole of outer pillar.
The further improvement of the utility model scheme is: described exhaust steam pipe comprises exhaust steam pipe and lower exhaust steam pipe, and lower exhaust steam pipe is upwards turned up and is communicated in exhaust steam pipe, and upper exhaust steam pipe outwards passes the set hole of protective housing.
The further improvement of the utility model scheme is: described exhaust steam pipe and core pipe are 90 ° of settings.
The further improvement of the utility model scheme is: described bellows is made by stainless steel.
Compared with prior art, the utlity model has following advantage:
One, avoid the interior steam impringement of compensator damaged and destroy thermal insulation layer, and the steam-condensation water soaking heat-preservation cotton spilt, make thermal insulation layer lose heat insulation effect, increase the heat loss of pipeline.
Two, avoid the steam that compensator leaks out to accumulate in outer pillar, thereby avoid outer pillar to bear high temperature, cause the appearance anticorrosive coat to come off, reduce pipeline problem in working life.
Three, be provided with gap can guarantee the normal flexible of core pipe and distortion between core pipe and protective housing owing to remedying device, thereby normal operation that also just can the protective core pipe.
Four, be convenient to implement targetedly maintenance, reduce the repair time, reduce earthwork excavated volume, save maintenance and operating expenses.
