Abstract
The utility model belongs to the technical field of the glass steel stack, a socket joint formula antiseep expansion joint is disclosed. Its main technical scheme including the upper and lower chimney section that is provided with bellmouth and socket respectively, passes through the fixed upper and lower expansion joint flange of flange bonding and the covering of connection respectively, setting up it keeps off the liquid circle to be provided with on the pipe wall in the last chimney section of bellmouth, be provided with the drain hole in the socket chimney section of above -mentioned expansion joint hypomere. This socket joint formula antiseep expansion joint can effectively solve the condensate and get into from the upper segment glass steel chimney section of thick bamboo wall flow under and form the problem to the corruption of expansion joint covering in the expansion joint. Make socket joint formula antiseep expansion joint have long service life's characteristics.
Description
Technical field
The utility model belongs to fiber glass reinforced plastic chimney technical field, namely relates to a kind of spigot and socket type leakage proof expansion joint be used on fiber glass reinforced plastic chimney or vertical gas pass.
Background technique
Expansion joint is also compensator or slip joint traditionally.By forming the covering (a kind of elastic element) of its operative body and holding the annexes such as pipe, support, flange, conduit to form.Expansion joint is the additional stress in order to compensate because temperature difference and mechanical vibration cause, and is arranged on a kind of flexible structure on container shell or pipeline.Utilize effective dilatation of its operative body covering, to absorb pipeline, conduit, container etc. by reason and the dimensional changes produced such as expanding with heat and contract with cold, or axial, the transverse direction of compensation pipes, conduit, container etc. and angular displacement.Also can be used for noise-and-vibration-reduction.Due to expansion joint as a kind of can the elastic compensation element of free-extension, there is the advantages such as reliable operation, functional, compact structure, be widely used in the departments such as chemical industry, metallurgy, nuclear energy.The expansion joint that container adopts, has various ways, with regard to the shape of ripple, applies the most extensive with U-shaped expansion joint, secondly also has Ω shape and C shape etc.The structure of suspension type fiber glass reinforced plastic chimney inner core is made up of the fiber glass reinforced plastic chimney inner core that several sections hang on the inner different heights platform of chimney, by can the expansion joint of free deformation connect between each segmentation, to expand with heat and contract with cold and vertical (horizontal stroke) that chimney horizontal displacement phenomenon causes affects to dilatation to eliminate.
In use, the air-flow risen in chimney inside directly touches expansion joint covering to current expansion joint, causes covering to be easily subject to the corrosion of flue gas; Meanwhile, covering also has more condensed fluid and assemble, make expansion joint place hydrops too much, not easily discharge, easily make expansion joint material by corrosion, reduce the working life of expansion joint.
Model utility content
The purpose of this utility model is just to provide a kind of can prevent flue gas and condensed fluid from entering spigot and socket type leakage proof expansion joint that expansion joint causes burn into long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of spigot and socket type leakage proof expansion joint, comprises the upper and lower chimney segment being respectively arranged with bellmouth and socket, the upper and lower expansion joint flange fixing respectively by flange bonding and the covering of connection; It is characterized in that: on the upper chimney segment inner tubal wall that described bellmouth is set, be provided with liquid retaining ring.
The additional technical feature forming above-mentioned spigot and socket type leakage proof expansion joint comprises:
---described liquid retaining ring has the tapering of setting;
---be provided with lap segment between described liquid retaining ring and described socket;
---on the socket chimney segment of described expansion joint hypomere, be provided with delivery hole.
Spigot and socket type leakage proof expansion joint provided by the utility model compared with prior art has the following advantages: one, owing to being provided with liquid retaining ring on the upper chimney segment inner tubal wall of bellmouth, the barrier that one stops flue gas is formed with lower end socket, the air-flow making expansion joint covering and chimney inside increase separates, effective minimizing flue gas is to the corrosion of expansion joint covering, this liquid retaining ring has the effect of water conservancy diversion condensed fluid simultaneously, condensed fluid can be made to flow down from epimere fibreglass epoxy stove-pipe barrel, lower cigarette saving tube is flow to along liquid barrier, therefore the condensed fluid with corrosivity can be effectively avoided to enter in expansion joint the corrosion formed expansion joint covering, extend its working life, its two, be provided with delivery hole in expansion joint lower end, the condensed fluid in expansion joint can be flowed out from delivery hole, effectively can prevent the generation of hydrops bottom expansion joint.
Accompanying drawing explanation
The structural representation of the spigot and socket type leakage proof expansion joint that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing, the structure of the spigot and socket type leakage proof expansion joint that the utility model provides and use principle are described in further details.
Be illustrated in figure 1 the structural representation of the spigot and socket type leakage proof expansion joint that the utility model provides.The structure of this spigot and socket type leakage proof expansion joint comprises: the upper and lower chimney segment 1 and 11 being respectively arranged with bellmouth 7 and socket 9, upper and lower expansion joint flanges 4,10 fixing respectively by flange bonding 2 and by pressing solidly the covering 6 that plate is connected with fixing bolt 5; What the upper chimney segment inner tubal wall 12 arranging bellmouth was provided with its underpart closes up is convenient to condensed fluid and can drops in the liquid retaining ring 3 with tapering in lower stack section.
In the structure of above-mentioned spigot and socket type leakage proof expansion joint, epimere fiber glass reinforced plastic chimney 1 is Wrapping formed with bellmouth 7 one, and expansion joint flange 4 is stuck with paste bonding with epimere fiber glass reinforced plastic chimney 1 fixed bonding by glass fibre reinforced plastics hand.The outside of covering 6 is with pressing solidly plate 5, and expansion joint flange 4, covering 6 and pressing solidly connects with bolt between plate 5 and reach the effect of sealing leakage proof.Liquid barrier 3 have certain tapering time bonding with epimere fiber glass reinforced plastic chimney 1 and and be provided with lap segment 13 between socket, this lap segment can freely be inserted in hypomere fiber glass reinforced plastic chimney 11.Liquid retaining ring 3 has the effect of water conservancy diversion condensed fluid, condensed fluid can be made to flow down from epimere fibreglass epoxy stove-pipe barrel, flow in hypomere fiber glass reinforced plastic chimney along liquid barrier 3, to avoid condensed fluid in the accumulation of expansion joint place too much.Liquid retaining ring 3 and socket 9 can form a barrier, and the air-flow making covering 6 and chimney inside increase separates, and effectively reduces flue gas to the corrosion of covering 6.The socket chimney segment of expansion joint hypomere is provided with delivery hole (bottom socket 9) and is provided with delivery hole 8, the condensed fluid in expansion joint can be discharged from delivery hole 8, effectively can prevent the generation of hydrops bottom expansion joint.
The chimney expansion joint that the utility model provides has the advantages that structure is simple, using effect is good.
