The utility model has simple and reasonable structure, the bracket and the inner wall of the sleeve pipe are in point and line contact, the contact area is small, and the frictional resistance is small. Certain gaps are formed between the direction guide plate, an ear plate and the inner wall of the sleeve pipe, so on the one hand, the stress of a pipeline system can not be increased under the heat expansion and cold contraction condition, and on the other hand, a steel heat bridge is separated, the energy saving effect is improved, and the heat pollution is reduced.

Description

The heat insulation guiding sliding cradling of a kind of steam tube

Technical field

The utility model relates to a kind of support device, specifically is a kind of heat insulation guiding sliding cradling of steam tube that is used to carry fluids such as high-temperature steam.

Background technique

In various productive lifes field; all need to arrange steam line; be energy saving; beautify the environment; existing steam line adopts buried mostly; the heat insulation type sliding support is a directly buried type prefabricated thermal insulation steam line significant components, and the reliability of its effect of heat insulation, work will be directly connected to operation heat waste, environmental protection and the safe operation of buried steam line.

Generally there are following two defectives in the sliding cradling that steam line of the prior art adopts: the base plate of (1) support contacts with the direct face of the inwall of sleeve pipe, sliding-frictional resistance is big, under the situation of expanding with heat and contract with cold, not only can produce bigger end thrust, but also can produce bigger noise and vibration support; (2) there is the heat bridge of steel in non-heat insulation type support, the thermal conductivity height of steel, heat-shielding performance is poor, not only wastes energy but also can produce thermo-pollution to facilities such as the power cable of ground flowers, plants and trees, underground vicinity, telecommunication cables, gives the safe operation of heat-net-pipeline and brings adverse influence working life.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of steam tube simple and reasonable, that compressive strength is high, heat-shielding performance is good heat insulation guiding sliding cradling.

The technological scheme that provides according to the utility model, the heat insulation guiding sliding cradling of described steam tube comprises pipe clamp, lower tube clip and heat insulation tile fragment, and described support is arranged between core pipe and the sleeve pipe, it is characterized in that: described upward pipe clamp and lower tube clip are semi-circular structure, its both sides are fixedly connected, form tubular structure, and described core pipe is positioned at this tubular structure, with its looping enclosed space, described heat insulation tile fragment is filled in this ring seal space; Be installed with guide plate directly over the described last pipe clamp outer wall, both sides, described lower tube clip outer wall below are installed with first supporting leg and second supporting leg respectively.

As further improvement of the utility model, described both sides of going up pipe clamp, lower tube clip have extended otic placode respectively, offer bolt hole on the otic placode, and last pipe clamp adopts bolt to be connected with lower tube clip.

As further improvement of the utility model, leave certain interval between described guide plate, otic placode and the internal surface of sleeve pipe.

As further improvement of the utility model, the angle between described guide plate, first supporting leg, second supporting leg is 120 degree.

As further improvement of the utility model, described guide plate adopts welding manner to be fixedly mounted on the pipe clamp; Described first supporting leg, second supporting leg adopt welding manner to be welded on the lower tube clip.

The utility model compared with prior art, and is simple and reasonable, and support is that line contacts with the inwall of sleeve pipe, and area of contact is little, and surface friction drag is little; Leave certain interval between guide plate, otic placode and the internal surface of sleeve pipe: on the one hand, under the situation of expanding with heat and contract with cold, can not increase the stress of pipe-line system, improve the Security of pipe-line system; On the other hand, cut off the heat bridge of steel, the sleeve pipe wall temperature is lower 5～10 ℃ than GENERAL TYPE support, improves energy-saving effect, reduces the thermo-pollution to the facilities such as power cable telecommunication cable of ground flowers, plants and trees, underground vicinity.
