Abstract
The utility model discloses a steam direct buried pipe thermal-insulation low-resistance rolling support which comprises a core pipe and an outer sleeve and further comprises a support body arranged between the core pipe and the outer sleeve. The support body is formed by a hoop and an auxiliary support body connected with the hoop in an equal-division mode, idler wheels are arranged at the ends of the auxiliary support body, the idler wheels are in rolling connection with the inner surface of the outer sleeve, and a thermal insulation pad is positioned between the core pipe and the hoop. Due to the fact that the thermal insulation layer is positioned between the core pipe and the hoop, steam heat energy radiation in the core pipe is greatly reduced, temperature drop of the unit length of a steam direct buried pipe is reduced, thermal insulation of the steam direct buried pipe is improved, and heat supply radius is greatly prolonged. Furthermore, slide friction connection between the movable support and the outer sleeve is changed into rolling connection, friction force between the movable support and the outer sleeve is greatly reduced, and service life of equipment is effectively prolonged.
Description
Technical field
The utility model relates to a kind of support device of pipeline, relates in particular to the heat insulation lower resistance rolling support of a kind of insulated steam pipe.
Background technique
Insulated steam pipe be a kind of be embedded in underground in order to lay the steam line of remote heat supply, comprise core pipe, outer sleeve and be located at thermal insulation layer between the two, steam circulates in the core pipe, thermal insulation layer is in order to reduce the temperature drop in the vapor transmission process, and outer sleeve plays the effect of isolated earth, support and protective core pipe, the structure that wherein thermal insulation layer is heat-preservation cotton and reflecting coating combination, core pipe and outer sleeve are metal material, support must be set to avoid causing thermal insulation layer distortion, impaired because of the weight effect of core pipe, and then affect heat insulation effect, the support arranged between steam direct-buried tube core pipe and outer sleeve is divided into two kinds of fixed support and sliding supports, travel(l)ing rest of the prior art is the interior pipe and the outer pipe that is enclosed within outer sleeve inner wall that are enclosed within core tube wall, the two connects with one heart with positioning rod, during the pipeline expanded by heating, interior pipe and core pipe and outer pipe and outer sleeve generation sliding friction, driving pipeline is only moving axially, by compensator equilibrium displacement amount, the travel(l)ing rest of this structure directly contacts with the core pipe, the amount that the heat energy of steam conducts to outer sleeve by support is more, the temperature drop value of unit length is larger, the distance that steam can be carried is shorter, frictional force between travel(l)ing rest and core pipe and outer sleeve is larger in addition, the pipeline that easily weares and teares, and the working life of equipment is relatively short.
Summary of the invention
The technical problems to be solved in the utility model is to provide the heat insulation lower resistance rolling support of a kind of insulated steam pipe, can solve the problem that existing travel(l)ing rest causes the high and pipeline that easily weares and teares of pipeline temperature drop value.
The utility model is achieved through the following technical solutions:
The heat insulation lower resistance rolling support of insulated steam pipe, comprise core pipe and outer sleeve, also comprise the travel(l)ing rest be arranged between core pipe and outer sleeve, the assistant support that described travel(l)ing rest is connected in clip by clip and decile forms, described assistant support end is provided with roller, described roller rolls and is connected in the outer sleeve internal surface, between core pipe and clip, is provided with thermal insulating pad.
The further improvement of the utility model scheme is that thermal insulating pad is combined by two semicircular structures.
The further improvement of the utility model scheme is that thermal insulating pad is the asbestos slate material.
The further improvement of the utility model scheme is that clip periphery decile is connected with three assistant supports.
The further improvement of the utility model scheme is, three assistant supports are arranged at respectively the neutral position between the chucking arm of clip periphery.
The further improvement of the utility model scheme is, assistant support comprises two supports, and is fixedly connected on the wheel shaft of two support ends, and described roller is movably connected on wheel shaft.
Compared with prior art, the utlity model has following advantage:
One, set up thermal insulating pad between travel(l)ing rest and core pipe, greatly reduce the heat energy emission of steam in the core pipe, reduced the unit length temperature drop value of insulated steam pipe, improved the heat insulation effect of insulated steam pipe, greatly extended heat range of heat;
Two, travel(l)ing rest is connected with sliding friction formula between outer sleeve to changing into rolls connects, greatly reduces the frictional force between travel(l)ing rest and outer sleeve, effectively extended the working life of equipment.
