Abstract
The utility model discloses a directly-buried steam pipe check ring type partition fixing support structure which comprises an annular supporting plate. The supporting plate is connected between the outer wall of a working pipe and the inner wall of an outer sleeve in parallel. Inner ring plates are arranged on the inner sides of connecting positions of the supporting plate and the working pipe. Outer ring plates are arranged on the outer sides of connecting positions of the supporting plate and the working pipe. An inner side reinforcing plate is arranged between the two inner ring plates. Outer side reinforcing plates are arranged on the outer sides of the outer ring plates. The fixing support structure has good stretch-and-contraction-resisting strength and good structural stability. The supporting plate is made of high-strength heat insulating materials, so that the structural stability is further improved, and heat loss of the working pipe is prevented at the same time. When the working pipe leaks, seepage water can flow out of a humidity discharging opening, and the general location of seepage can be determined easily through the humidity discharging opening, so that quick maintenance can be conducted conveniently.
Description
Technical field
The utility model belongs to pipe-line equipment technical field, relates to a kind of Buried Steam Pipe back-up ring type and cuts off fixing rack structure.
Background technique
Steam conveying pipe is generally comprised of working pipe and outer sleeve, between working pipe and outer sleeve, by supporting structure, be fixedly connected with, current commonplace employing be single ring baffle structure, owing to being 90 ° of angles between baffle plate and working pipe and outer sleeve, therefore between working pipe and outer sleeve during along pipeline direction generation telescopic moving, the welding part of baffle plate and working pipe and outer sleeve is easy to tear, less stable.In addition, existing baffle plate effect of heat insulation is poor, makes steam heat by working pipe be lost to and in stratum, cause meaningless heat loss along baffle plate and outer sleeve.
Model utility content
Main purpose of the present utility model is to provide a kind of Buried Steam Pipe back-up ring type and cuts off fixing rack structure, solves existing Buried Steam Pipe supporting structure poor stability and the not good defect of effect of heat insulation.
In order to realize goal of the invention, the technological scheme that the utility model adopts is, a kind of Buried Steam Pipe back-up ring type cuts off fixing rack structure, include some groups of annular backup pads that arrange with constant spacing along working pipe and outer sleeve pipeline direction, every group of dunnage arranges two, two dunnages are connected between the outer wall of working pipe and the inwall of outer sleeve side by side, the inner side, joint of dunnage and working pipe is respectively arranged with inner ring plate, the outside, joint of dunnage and outer sleeve is respectively arranged with outer ring plate, between two inner ring plates, be provided with inner side stiffening plate, outer ring plate arranged outside has outer stiffening plate.
Feature of the present utility model is also, on the outer sleeve in two dunnage outsides, is respectively arranged with humidity discharging mouth, and humidity discharging mouth is communicated with the space between outer sleeve working pipe with ambient atmosphere.
The joint of humidity discharging mouth and outer sleeve is provided with humidity discharging mouth stiffening plate.
The beneficial effects of the utility model are:
1) the utility model arranges inside and outside ring flat-plate and stiffening plate by the joint at dunnage and working pipe and outer sleeve, increase its anti-flexible intensity and structure stability, thereby can avoid working pipe and outer sleeve due to the risk that weld is torn when the relative movement of pipeline direction of expanding with heat and contract with cold;
2) dunnage of the present utility model adopts high-strength heat isolating material, not only further strengthens its structure stability, can prevent that the heat of working pipe runs off simultaneously;
3) when working pipe generation seepage, infiltration can be flowed out by humidity discharging mouth, is easy to determine the Position Approximate of seepage by humidity discharging mouth, is convenient to Quick overhaul.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. working pipe, 2. outer sleeve, 3. dunnage, 4. inner ring plate, 5. outer ring plate, 6. interior stiffening plate, 7. external reinforcing plate for car, 8. humidity discharging mouth, 9. humidity discharging mouth stiffening plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of Buried Steam Pipe back-up ring type to cut off fixing rack structure, as shown in Figure 1, include the some groups of annular backup pads 3 that arrange with constant spacing along working pipe 1 and outer sleeve 2 pipeline directions, every group of dunnage 3 arranges two, two dunnages 3 are connected between the outer wall of working pipe 1 and the inwall of outer sleeve 2 side by side, dunnage 3 is respectively arranged with inner ring plate 4 with the inner side, joint of working pipe 1, dunnage 3 is respectively arranged with outer ring plate 5 with the outside, joint of outer sleeve 2, between two inner ring plates 4, be provided with interior stiffening plate 6, outer ring plate 5 arranged outside have external reinforcing plate for car 7.
During concrete enforcement, along working pipe 1 and outer sleeve 2 pipeline directions, every 30-50 rice, one group of annular backup pad 3 is set, between two dunnages 3, leave gap and along the radial arrangement of working pipe 1 and outer sleeve 2, endoporus is nested on working pipe 1 outer wall, outer rim is connected on outer sleeve inner wall, dunnage 3 is divided into different enclosed spaces by the space between working pipe 1 and outer sleeve 2, can fill insulant material in enclosed space.Dunnage 3 adopts thermal-protective material to make, and can reduce the heat turnover rate of working pipe 1.Inner side and working pipe 1 that inner ring plate 4 is pasting dunnage 3 weld together, and outer ring plate 5 is pasting dunnage 3 outsides and outer sleeve 2 welds together.Interior stiffening plate 6 and external reinforcing plate for car 7 all arrange along the pipeline direction of working pipe 1 and outer sleeve 2, can strengthen the structure stability of dunnage 3, interior stiffening plate 6 is rectangular plate, be welded between two inner ring plates 4, outer ring plate 7 has two right angle sides, and two right angle sides weld together with outer ring plate 5 and outer sleeve 2 inwalls respectively.Adopt inner ring plate 4, outer ring plate 5 and interior stiffening plate 6, external reinforcing plate for car 7 can make the linkage structure of dunnage 3 more stable, strengthen dunnage 3 resistance working pipe 1 and outer sleeve 2 along the strength of pipeline Direction distortion.
Outer sleeve 2 is owing to being directly embedded in soil layer, and because the effect of various external force is easy to breakage, the moisture in soil layer can infiltrate in thermal insulating material, and humidity discharging mouth 8 can be discharged the moisture infiltrating in thermal insulating material.Fast detecting when the different enclosed spaces that segmentation simultaneously forms are also beneficial to pipeline maintenance, when seepage occurs working pipe 1, the moisture of discharge is discharged by humidity discharging mouth 8, can be determined the Position Approximate of breakthrough by the position of humidity discharging mouth 8.Humidity discharging mouth 8 is connected and fixed by humidity discharging mouth stiffening plate 9 with the joint of outer sleeve 2, strengthens its structure stability.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model; above-mentioned mode of execution and specification are principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by claims and equivalent thereof.
