Abstract
The utility model relates to an improved expansion compensation joint with cooling water pipe. The priorexpansion compensation joint has the defects that the radiating effect is not good and the priorexpansion compensation joint is easily deformed under the circumstances of large temperature difference of the inside and outside and even is totally damaged. The utility model comprises a basal body arranged at the external side of a thermal insulation layer and a cooling layer arranged at the internal side of the thermal insulation layer. The cooling layer consists of snake-shaped metal water pipes vertically arranged along the external side of the thermal insulation layer. Two ends of the metal water pipe are connected with an upper flange and a lower flange and are respectively provided with a water inlet and a water outlet. The utility model is suitable for smoke flue and the hot air duct with the advantages of good radiating effect and high temperature resistance and avoids the self deformation of the expansion compensation joint as well as reduces manufacture cost.
Description
The utility model relates to a kind of modified model slip joint that is used for the band water-cooling tube of gas pipeline.
Compensatory poor, the shortcoming such as extending amount is little of the multidimensional that exists at the flue of industries such as electric power, metallurgy, building materials, chemical industry and the slip joint of hot air duct (also claiming expansion joint), I disclose the soft slip joint of a kind of hybrid type in a utility model patent (ZL 91223696.5) of application in 1991, it is matrix with the metallic material, increased the metal mesh type separation sleeve, improved its corrosion resistance and wear-resisting wiping, the multidimensional compensation performance of thermal expansion also improves.But this kind slip joint adopts nonmetallic material to make the slip joint main body, is subjected to the stable on heating limitation of nonmetallic material, is difficult to bear for a long time the high temperature more than 1000 ℃.At this defective, I have applied for a utility model patent (ZL 95208626.3) in nineteen ninety-five again, it discloses a kind of flexible slip joint, this slip joint is provided with lower water jacket in matrix that nonmetallic material are formed and heat insulation layer, reach the purpose of cooling by the circulation of cooling water in the water jacket, make the operating temperature of slip joint can be increased to 1000 ℃-1500 ℃, service behaviour is further improved.Gather in the water jacket lower end because the water in the water jacket is often heavy, caused heat radiation inhomogeneous, make the radiating effect of water jacket upper half part relatively poor, cooling-down effect is still not fully up to expectations.When the internal layer temperature is more than 1000 ℃ the time, skin only is 100-200 ℃, and significantly internal-external temperature difference makes the slip joint self-deformation, causes metal framework to damage when serious, and slip joint is scrapped.In addition,, the heat insulation layer material is required corresponding raising, make its cost higher because radiating effect is inhomogeneous.
The purpose of this utility model is to overcome above-mentioned defective, in the multidimensional compensation performance that keeps thermal expansion simultaneously, provides a kind of good heat dissipation effect, improves the modified model slip joint of slip joint body quality.
The utility model is to realize like this, the modified model slip joint comprises matrix that is arranged on the heat insulation layer outside and the cooling layer that is arranged on the heat insulation layer inboard, cooling layer is made of the metallic water pipe that is looped around the heat insulation layer inboard, described metallic water pipe is the snake type, arrange along the heat insulation layer inboard, upright, the water pipe two ends link to each other with last lower flange respectively, and are respectively equipped with the entery and delivery port of cooling water, described intake-outlet is interchangeable, and promptly water intake also can become water outlet.Snake type metallic water pipe evenly distributes around heat insulation layer is inboard, must specially not pressurize, can make cooling water be full of the whole inner chamber of metallic water pipe, be that current from bottom to top or from top to bottom flow along pipeline, make on the modified model slip joint body each several part Homogeneouslly-radiating next week, radiating effect improves greatly, and water intake is provided with control valve, the control flows water yield easily is to satisfy various cooling requirements.
Described a kind of modified model slip joint, there is annular upper and lower positioning ring the heat insulation layer inboard, and snake type metallic water pipe is fixed on the upper and lower positioning ring, to guarantee its stability.
Described a kind of modified model slip joint, the metallic water pipe that constitutes cooling layer can be two groups, communicates with each other or is arranged in parallel, and increases radiating effect to improve.Each is organized metallic water pipe and can communicate and be integral the formula cooling recirculation system, also can constitute independently two groups of cooling systems.
The modified model slip joint of this structure, solved the defective of prior art,, made cooling water reduce the inside temperature of slip joint effectively by the setting of metallic water pipe, improved the service behaviour of slip joint, made it can satisfy 1000 ℃-1500 ℃ working condition requirement.The annular endless metal water pipe of last body next week makes cooling-down effect be tending towards desirable.Owing to good heat dissipation effect, avoided the self-deformation of slip joint, the requirement reduction to the heat insulation layer material has also reduced manufacture cost.
Below in conjunction with Figure of description and concrete mode of execution the utility model is described in further detail.
Fig. 1 is one of the utility model embodiment's a structural representation.
Fig. 2 is the utility model embodiment's two a structural representation.
As shown in Figure 1, the modified model slip joint comprises matrix 2, cooling layer 3 and the heat insulation layer between matrix and cooling layer 1.Matrix 2 adopts ductility nonmetallic material such as silicon, fluorine rubber cloth, F4 varnished cloth, poly-tetrem fluorine alkene film to make, and the two ends folding is translated into flange edge, and is provided with several connection screws.Heat insulation layer 1 is made cylindric, and there is upper and lower positioning ring 9,10 its inboard.Cooling layer 3 is made of the snake type metallic water pipe 4 that is fixed on the upper and lower positioning ring, and promptly snake type metallic water pipe 4 is along heat insulation layer 1 inboard, upright, arrange a week equably; Also can be laterally inboard or evenly distributed up and down in other mode that is equal to along heat insulation layer.The refractory material filling can be used in the gap of snakelike conduit.Metallic water pipe 4 two ends link to each other with upper and lower flange 5,6 respectively, are respectively equipped with water intake 7, water outlet 8 on the upper and lower flange, and this water intake is provided with control valve, and it is interchangeable with water outlet.Cooling water enters water intake, after the metallic water pipe circulation, flows out water outlet, forms the cooling water circulation canal.
Snakelike metallic water pipe can also many groups be provided with, shown in Fig. 2 embodiment, the snakelike metallic water pipe that constitutes cooling layer is two groups, each group metallic water pipe is installed entery and delivery port respectively, cooling water enters two water intakes 7,11 of metallic water pipe respectively, after the metallic water pipe circulation, flow out water outlet 8,12 separately respectively, promptly two groups of metallic water pipe have the cooling channel of one's own.Also can be connected as a body between them and constitute compound cooling channel.
