Abstract
The utility model relates to a heat insulation fixed support for a steam direct burial thermal insulation pipe. The heat insulation fixed support for the steam direct burial thermal insulation pipe comprises a working steel pipe and an outer sleeve pipe which is sleeved outside the working steel pipe, wherein inner sealing plates and outer sealing plates are arranged between the working steel pipe and the outer sleeve pipe, the inner sealing plates and the outer sealing plates are welded on the outer wall of the working steel pipe and the inner wall of the outer sleeve pipe in a double-side mode, reinforcing ribs are arranged in the sealing plates, therefore the sealing plates are prevented from moving when thrust which is produced due to thermal expansion of the working steel pipe is exerted on the sealing plates, and the sealing plates are made of materials with good heat-insulating performance and good flexibility. The heat insulation fixed support for the steam direct burial thermal insulation pipe enables a pipeline to be conveniently maintained and detected, improves thermal insulation effects, is good in heat insulation effect, achieves a goal of preventing a heat source from slowly spreading and leaking, indirectly prevents hot environmental pollution and protects and afforests the environment.
Description
Technical field
The utility model relates to a kind of support stand, relates in particular to the heat insulation fixed support of the good steamy thermal insulated direct-buried pipe of a kind of heat-shielding performance.
Background technique
Steamy thermal insulated direct-buried pipe in use at present, the green belt that all occurs above the underground pipe is withered, analyze its reason, mainly be due to the heat volatilization of underground pipe, because of the fixed support of direct-buried insulated pipe mainly plays fixedly inner and outer pipes effect in the direct-burried pipe network, the one, the requirement inner and outer pipes is not subjected to displacement, the 2nd, function of heat insulation is played in requirement, make the temperature at this place consistent with peripheral environment, because during design direct-buried insulated pipe fixed support, only from mechanics angle calculation stressing conditions, ignore the thermomechanics effect, fixing between the inner and outer pipes all adopted the steel plate ring, and directly welding is fixing, thereby when media such as interior pipe delivering vapor, interior pipe temperature reaches about 250 ℃, and interior pipe temperature directly is transmitted to outer sleeve by the steel plate ring, and the steel outer sleeve is reached about 150 ℃ to temperature, this loses a large amount of energy on the one hand and causes significant wastage to enterprise, produce environmental thermal pollution around giving pipe on the other hand, if direct buried pipe bury when more shallow, directly cause ground green belt overheated and withered.
Summary of the invention
The utility model provides the good steamy thermal insulated direct-buried pipe of a kind of heat-shielding performance heat insulation fixed support at above deficiency.
The technological scheme that the utility model adopted is:
The heat insulation fixed support of a kind of steamy thermal insulated direct-buried pipe, comprise working steel tube and be enclosed within the outer outer sleeve of working steel tube, be provided with inside and outside sealing plate in working steel tube and the outer sleeve, inside and outside sealing plate welding by both sides is connected on the inwall of working steel tube outer wall and outer sleeve, stiffening rib is housed in the sealing plate, prevents that sealing plate is subjected to the thrust that the working steel tube thermal expansion produces and moves; Sealing plate is that good and flexible good material is made with heat-shielding performance.
Be provided with attachment hole on the described sealing plate, and connect with the link of ceramic material.
The utility model beneficial effect is:
Be convenient to the maintenance and the detection of pipeline, improved heat insulation effect, good heat-insulation effect reaches the purpose that stops the chronic diffusion of thermal source, leakage, prevents thermal environment pollution protection greening environment indirectly.
