Description
Technical field
The utility model belongs to heat supply pipeline technical field, and in particular to a kind of alarm emergency compensator.
Background technology
Heat supply unit is by heat distribution pipe network using hot media as carrier to heat unit heat supply, the pipeline meeting of its heating network
Produce that thermal expansion is elongated by cold heating, again the retraction of pipeline can be caused to shorten after stopping heat supply.
In order to solve the problem of expanding with heat and contract with cold of thermal pipe, at present, compensator, the benefit are mostly connected with heat supply pipeline
Repaying the structure of device is, by the both ends of the bellows of redeeming, is connected to the outer tube of adjustable pipe and fixing pipe opposite end
On wall, while the fixing pipe pipe end that the termination of adjustable pipe one end is inserted in corresponding thereto forms nestable shape, then by adjustable pipe
With termination of the fixing pipe from nestable one end, be connected on each self-corresponding heat supply pipeline, so by bellows it is flexible with
And the movement of adjustable pipe, the harmomegathus of heat supply pipeline is compensated.
In order to prevent when compensator continually works, adjustable pipe chromium coating comes off or cut seriously causes heating agent herein
Place's leakage, therefore be nested in fixing pipe and adjustable pipe in one section of annular space between section tubular wall, provided with can be from fixing pipe
The ring packing letter of graphite powder filler is added outside tube wall.Although above-mentioned compensator serves good benefit to the harmomegathus of heat supply pipeline
The effect of repaying, but when compensator frequent operation, it is added to the graphite of ring packing letter outside the fixation tube wall of compensator
Powder filler can produce consumption, once graphite powder filler be depleted to it is a certain amount of, also have not enough time to supplement addition filler when, hot media
It can be nested between section tubular wall and leak from fixing pipe and adjustable pipe, so not only waste the energy, improve heat cost, and
And also surrounding environment is polluted；And when leaking generation, it is not easy to be found in time as leakage rate is smaller, is not easy to find standard
True leak position, it is larger to leakage rate, because without early warning is discovered in advance, quite unexpected, emergency plan prepares hastily, not only
Need to stop heat supply immediately to be repaired, and because various repair materialses are not got all the ready in advance, expend a large amount of manpower and materials, stop
Hot time length, caused by social influence it is extremely serious.
