Abstract
The utility model provides a high-temperature resistant pipeline expansion jointb which is composed of connecting pipes, bellows, a sealing heat insulating body and an inner sleeve, wherein, both ends of the bellows are connected with the inner walls of the two connecting pipes, the sealing heat insulating body is arranged below the bellows, and the inner sleeve is arranged in the sealing heat insulating body. Compared with the prior art, the utility model has the characteristics of simple structure, reasonable design, convenient installation and use, easy processing and fabrication, good performance of displacement compensation, high temperature resistance, small rigidity, long cycle life, etc.
Description
The utility model relates to a kind of pipe conveying equipment, specifically a kind of high temperature resistant pipeline expansion joint that is used on high-temperature gas or the hot blast conveying pipe road.
At metallurgy, cement, on high-temperature gas in the industry such as thermoelectricity or the high-temperature hot-air conveyance conduit, in frequent process of expansion and contraction, pipeline is snapped for fear of pipeline, distortion or fracture, need on the pipeline of a segment distance, install the expand with heat and contract with cold pipe expansion joint of stress of a buffering pipe additional, the most frequently used pipe expansion joint generally is the cydariform expansion joint, its structure is to abandon to be welded on the pipeline with ring steel plate to form, it is that resistance to high temperature is poor that this cydariform expansion joint in the prior art uses the deficiency of existence aborning, compensation performance is low, easily snap, the stress cycle life-span is low, sealability is low, installation and maintenance inconvenience etc.
The purpose of this utility model provides that a kind of energy is high temperature resistant, corrosion-resistant, good seal performance, cycle life height, the high temperature resistant easily pipeline expansion joint of installation and maintenance.
High temperature resistant pipeline expansion joint of the present utility model its objective is realization in the following manner, make primary element with the bellows that excellent spring cycle life is high, below bellows, install the sealing insulator additional, the low short deficiency of cycle life that the high temperature scholar change that causes to solve the thin non-refractory of ripple tube wall or burn etc. causes, installing inner sleeve additional in the centre of taking over play the guiding role, avoid the post unstability, also can advance the thermal insulation and the sealing of a raising bellows.
The structural representation of the high temperature resistant pipeline expansion joint that accompanying drawing is.
With reference to Figure of description to high temperature resistance pipeline expansions ection of the present utility model do with Under explain.
High temperature resistance pipeline expansions ection of the present utility model, its structure be by take over [1], Bellows [5], sealing insulator, inner sleeve [6] form two of bellows [5] The inwalls that end and two is taken over [1] join, and seal insulator and are installed in bellows [5] Below, inner sleeve [6] are installed in the centre of sealing insulator. The sealing insulator is Formed the heat-insulating and sealing ring in the middle of wherein being installed in by three heat-insulating and sealing rings [2] [2] be to be made with refractory material by wire netting [8] bag, be installed in two of its both sides Heat-insulating and sealing ring [2] is that it is disconnected by Plate Welding is taking over that [1] mouth of pipe forms Face is the ring-type tube chamber of rectangle, and fills in the ring-type tube chamber with the refractory material composition, For the ease of filling fire resisting material, the ring-type of joining at the heat-insulating and sealing ring with the centre Have refractory material filler [9] on the wall of the lumen. Inner sleeve [6] is installed in adapter [1] centre is on the inwall of inner sleeve [6] and the both sides of sealing heat insulation loop [2] Be fixed with high-temperature refractory [7] on the inwall of adapter [1], anti-in order to strengthen high temperature Fire material fastness, on the inwall of taking over [1] and the inwall of inner sleeve [6] weld Be connected to the high-temperature refractory attachment [10] that heat-resisting reinforcing bar is made.
Embodiment:
High temperature resistant pipeline expansion joint processing and fabricating of the present utility model is very simple, make shown in the by specification accompanying drawing and get final product, at first bellows is welded on the mouth of pipe of two tube couplings, then high-temperature refractory is risen with the wire netting bag and make the below that the heat-insulating and sealing ring is installed in bellows, two heat-insulating and sealing rings in the outside are welded on by steel plate to be taken on the mouth of pipe, form two ring-type tube chambers that section is a rectangle, the ring-type tube chamber of the filler that the ring-type wall of the lumen of the rectangle that joins from the heat-insulating and sealing ring with the centre is left refractory material being packed into, at last inner sleeve is installed in two centres of taking over, and on the inwall of inner sleeve, install one deck refractory material additional, on two inwalls of taking over, weld the refractory material fixed block made from reinforcing bar, and on the inwall of taking over, install refractory material equally additional.The installation of this kind is high temperature resistant pipeline expansion joint coexists mutually substantially with installing and using of the pipe expansion joint of other kinds that this does not repeat with using.
High temperature resistance pipeline expansions ection of the present utility model is compared with existing technology, and has Simple in structure, reasonable in design, easy to install, be easy to processing and fabricating, compensation Displacement performance is good, and is high temperature resistant, and rigidity is little, and the cycle life high has Good popularizing value.
