Abstract
The utility model relates to a directly-buried steam pipe, in particular to a compensation elbow used for a steam pipe. The compensation elbow comprises a working pipe, an outer protection pipe, a heat preservation layer and a support set. The support set is arranged between the working pipe and the outer protection pipe. The heat preservation layer is located between the working pipe and the outer protection pipe. When the pipe is operated, an inner rotating support structure, the heat preservation layer and the outer protection pipe are overall displaced, it is guaranteed that the working pipe and the heat preservation layer relatively move, the heat preservation layer is protected from damage by an inner air layer, the integrity of the heat preservation layer is kept, heat losses of the pipe are reduced, the temperature of the outer surface of the outer protection steel pipe is reduced, an anticorrosive layer is protected, and the service life of the pipe is prolonged.
Description
Technical field
The utility model relates to a kind of compensation elbow, specifically relates to a kind of compensation elbow for steam line, and it belongs to steam heat preserving pipeline field.
Background technique
At present, in the pipe network for delivery of high-temperature steam, modal compensation way has: a, compensator compensates b, elbow compensation.Compensation elbow is compared with compensator, because having, cost is low for it, long service life, flexible naturally compensate the advantage such as safe and reliable and be usually applied to carrying in high-temperature steam pipe network, certainly its drawback is that roughly hull-skin temperature is higher in heat bridge radiation loss, heat-preservation cotton is by irregular extruding, affect heat insulation effect, the problems such as the limited flexibility that compensation elbow slides.
Summary of the invention
In view of the problem of prior art existence, the purpose of this utility model is to provide a kind of compensation elbow for steam line, its structure fabrication is simple, easy for installation, structure directing better function, being used in buried steam line can be to the motion of any compensation direction, both ensure the flexibility of elbow compensation, realized again the support to keeping warmth space.
To achieve these goals, the technological scheme that the utility model adopts is the compensation elbow for steam line, it comprises: work elbow, outer pillar and support, described support is arranged between work elbow and outer pillar, it is characterized in that: described support comprises: supporting plate, universal wheels, support ring and nano heat insulating material, between support ring and work elbow, be provided with thermal-protective coating, described support ring is provided with universal wheels away from work elbow one side; Universal wheels contacts with supporting plate, and described supporting plate is fixed on outer pillar; Described universal wheels and supporting plate are two groups, and described two supporting plates are parallel, the perpendicular bisector of supporting plate for vertically to and by by the center of circle, work elbow cross section.
The core wheel of described two universal wheelss is located along the same line, and straight line is vertical direction.
Described work elbow cross section and outer pillar cross section are concentric circle.
Described universal wheels is that line contacts with supporting plate.
Described two supporting plates are identical to the perpendicular distance of work elbow.
Described support is positioned at the center of work elbow.
The utility model has the advantage of: between support ring and work elbow, add nano heat-insulating layer, reduced to a great extent heat bridge heat transfer, reduced the temperature of outer surface; Between support ring and supporting plate, distance is certain, and upper and lower supporting plate plane is about elbow working steel tube axis above-below direction symmetry, and the axial connecting line of two universal wheelss is vertical direction, forms the motion to any compensation direction, has both ensured the flexibility of elbow compensation; Prevent again elbow unstability up and down, greatly reduce the jerk of elbow, reducing this jerk can be to avoiding the destruction to external protective steel tube; Better protect elbow working pipe by the line contact friction between wheel and supporting plate.And rolling support is designed in the center of elbow, is to have avoided the amount of deflection that causes due to the deadweight of elbow working steel tube, thermal insulation layer.
