Abstract
The invention discloses a steam straight buried pipe heat insulation low resistance rolling bracket, which comprises a core pipe and an outer sleeve; and further comprises a bracket arranged between the core pipe and the outer sleeve, wherein the bracket is composed of a hoop and a secondary bracket connected to the hoop equally; a roller is arranged at the end part of the secondary bracket; the roller is in rolling connection to the internal surface of the outer sleeve; and a heat resistance pad is arranged between the core pipe and the hoop. The bracket is added with the heat resistance pad at a movable bracket and a core pipe bracket, thereby largely reducing the heat energy emission quantity of steam in the core pipe; reducing the unit length temperature drop value of a steam straight buried pipe; increasing the heat insulation effect of the steam straight buried pipe; largely prolonging the heat-supplying radius; and the sliding friction connection between the movable bracket and the outer sleeve is changed into rolling connection, thereby largely reducing the friction force between the movable bracket and the outer sleeve and effectively prolonging the useful life of the device.
Description
Technical field
The present invention relates to a kind of support device of pipeline, relate 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 then plays the effect of isolated earth, support and protective core pipe; Wherein thermal insulation layer is the structure of heat-preservation cotton and reflecting coating combination, and core pipe and outer sleeve are metal material, support must be set avoiding causing thermal insulation layer distortion, impaired because of the weight effect of core pipe, and then affect heat insulation effect; The support that arranges between steam direct-buried tube core pipe and the 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 heat energy of steam is more by the amount that support conducts to outer sleeve, the temperature drop value of unit length is larger, and the distance that steam can be carried is shorter; Frictional force between travel(l)ing rest and core pipe and the 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 problem to be solved in the present invention provides 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 present invention 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 that is arranged between core pipe and the outer sleeve, described travel(l)ing rest is made of the assistant support that clip and five equilibrium are connected in clip, described assistant support end is provided with roller, described roller rolls and is connected in the outer sleeve internal surface, is provided with thermal insulating pad between core pipe and clip.
The further improvement of the present invention scheme is that thermal insulating pad is combined by two semicircular structures.
The further improvement of the present invention scheme is that thermal insulating pad is the asbestos slate material.
The further improvement of the present invention scheme is that clip periphery five equilibrium is connected with three assistant supports.
The further improvement of the present invention scheme is, three assistant supports are arranged at respectively the neutral position between the chucking arm of clip periphery.
The further improvement of the present invention 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 present invention has following advantage:
One, between travel(l)ing rest and core pipe, sets up thermal insulating pad, 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 prolonged heat range of heat;
Two, travel(l)ing rest is connected with sliding friction formula between the outer sleeve changing into rolls connects, greatly reduces the frictional force between travel(l)ing rest and the outer sleeve, effectively prolonged the working life of equipment.
