Abstract
The invention relates to a steam pipeline compensator which comprises an outer sleeve and a core barrel, wherein an anti-pull ring is arranged at the sleeving-in end of the core barrel; an inner baffle ring corresponding to the anti-pull ring is arranged on the inner wall of the outer sleeve; a separation ring with a hole in the outer wall is sleeved on the core barrel; an annular main filler sealing cavity is formed between the separation ring and the inner baffle ring; a pressure cover sleeved with the core barrel is fixed at the right end of the outer sleeve; an annular auxiliary filler sealing culvert is formed between the baffle ring and the pressure cover. The steam pipeline compensator is characterized in that the hole is formed in the outer wall, which corresponds to an separation ring, of the outer sleeve and a storage tank is hermetically connected with the hole; low-melting-point metal or alloy with the melting point lower than 90 DEG C is arranged in the storage tank. The steam pipeline compensator has the advantages that the advantages of an underground maintainable sleeve compensator are kept and the steam leakage phenomenon of the compensator is avoided.
Description
Technical field
The present invention relates to a kind of steam pipeline compensator, belong to pipeline compensator field.
Background technique
Pipeline compensator mainly solves the problem of expanding with heat and contract with cold that pipeline causes because of temperature variation, eliminates pipeline internal stress, makes the operating mode that pipe network keeps good.At present, the compensation way of steam pipeline compensator mainly contains three kinds of forms: one is natural compensation, and two is that metal bellows compensates, and three is that sleeve expansion joint compensates.All there is certain deficiency in above three kinds of compensation ways.Natural compensation refers in steam line installation process, and straight section pipeline arranges one every certain spacing, and " U " shape is curved, " Z " shape is curved, or " L " shape is curved, utilizes the resiliently deformable of pipeline to realize the cold and hot compensation of pipeline.Its advantage is: durable, not leakiness vapour, and bearing capacity is high; Its shortcoming is: take up room compared with large, investment is large, compensation rate is little.It is arrange one section of metal bellows every certain spacing on the straight section pipeline of steam line that metal bellows compensates, and its advantage is: take up room little, in its fatigue range, do not leak vapour; Its shortcoming is: bearing capacity is low, and due to the temperature fluctuation of most steam line large, pipeline flexible often, action very easily causes the fatigue of bellows frequently, and its working life is greatly reduced.The advantage that sleeve expansion joint compensates is: compensation rate is large, it is little to take up room, bearing capacity is high; Shortcoming is: can not safeguard, use in easily leak vapour, maintenance load is large, seldom uses now.For above-mentioned the deficiencies in the prior art, the applicant once devised buried maintainable sleev compensator on the basis of sleeve expansion joint, the patent No.: 2004101010242, it comprises outer sleeve and core cylinder, twice packing seal letter is provided with between outer sleeve and core cylinder, with graphite packing, ducted steam is sealed, and after the buried use of compensator, compensator can be observed on the ground and whether have media leaks, and mending-leakage measure can be implemented on the ground, not only greatly increase the operational reliability of compensator, also the working life of compensator is extended, reduce the maintenance cost of pipe network.But this technology can not stop the generation that compensator leaks vapour phenomenon.
Summary of the invention
The object of the invention is to provide a kind of for buried maintainable sleev compensator and can stop the steam pipeline compensator that compensator leaks the generation of vapour phenomenon.
For solving the problems of the technologies described above, the invention provides following technological scheme:
Steam pipeline compensator of the present invention, comprise outer sleeve and core cylinder, be provided with anti-pull out ring at the end that is inserted in of core cylinder, be provided with at the inwall of outer sleeve and pull out inner baffle ring corresponding to ring with anti-, on core cylinder, cover has spacer ring with holes on outer wall, the main packing seal letter of ring-type is defined between spacer ring and inner baffle ring, be fixed with at the right-hand member of outer sleeve and overlap the gland of core cylinder, the auxiliary packing seal letter of ring-type is defined between spacer ring and gland, it is characterized in that: perforate on the outer wall corresponding with spacer ring of outer sleeve the storage tank that is tightly connected in perforate, fusing point is housed lower than the low melting metal of 90 DEG C or alloy in storage tank.
Advantage of the present invention is: the advantage maintaining buried maintainable sleev compensator, and has stopped the generation that compensator leaks vapour phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to accompanying drawing, the present invention includes outer sleeve 1 and core cylinder 2, be provided with anti-pull out ring 6 at the end that is inserted in of core cylinder, be provided with at the inwall of outer sleeve and pull out inner baffle ring corresponding to ring 4 with anti-, on core cylinder, cover has spacer ring 5 with holes on outer wall, the main packing seal letter 7 of ring-type is defined between spacer ring and inner baffle ring, in main packing seal letter, graphite grazing filler is housed, be fixed with at the right-hand member of outer sleeve and overlap the gland 3 of core cylinder, the auxiliary packing seal letter 8 of ring-type is defined between spacer ring and gland, in auxiliary packing seal letter, graphite grazing filler is housed, perforate on the outer wall corresponding with spacer ring of outer sleeve the storage tank 9 that is tightly connected in perforate, fusing point is housed lower than the low melting metal of 90 DEG C or alloy in storage tank.Described low-melting alloy, refers to the low melting alloy of fusing point lower than 232 DEG C (fusing points of Sn); Usually be made up of low melting metal elements such as Bi, Sn, Pb, In.Low-melting alloy comprises 47 DEG C of low-melting alloys, 50 DEG C of low-melting alloys, 55 DEG C of low-melting alloys, 60 DEG C of low-melting alloys, 70 DEG C of low-melting alloys, 92 DEG C of low-melting alloys, 120 DEG C of low-melting alloys, 138 DEG C of low-melting alloys, 180 DEG C of low-melting alloys etc., the low-melting alloy that the present invention selects is fusing point lower than the low-melting alloy of 90 DEG C or metal, especially normal temperature liquid metal, as: the liquid metal under the normal temperature that the Chinese Academy of Sciences produces.
During application, after compensator is connected with pipeline, storage tank is positioned at the top of compensator outer sleeve, and tank mouth is downward.When store in storage tank be solid-state compensator low melting metal time, as long as after ducted vapor (steam) temperature reaches the fusing point of low melting metal, low melting metal is just molten into liquid, liquid metal flows on spacer ring under gravity again by the hole flowing on spacer ring, spacer ring and all gaps between outer sleeve and core cylinder are all filled up, make to seal completely between winner's packing seal letter and auxiliary packing seal letter to completely cut off, if what store in storage tank is liquid metal under normal temperature, then the gap around the direct dirty filling spacer ring of liquid metal; The stop that will be subject to liquid metal when steam penetrates the sealing of sealed letter moves up and gets in storage tank 9, when in the pressure in storage tank and pipeline, vapor pressure reaches balance, the pressure of the liquid metal around spacer ring will be greater than the vapor pressure in pipeline, so just prevent steam to exosmosis, thus ensure that compensator does not leak steam.
