Abstract
The utility model discloses a kind of directly buried compensation device sealing thermal insulation structure, and a heat preservation left side is taken over, thermal-insulation coat pipe is arranged on the outside of a left side for directly buried compensation device is taken over, and the heat preservation right side, which is taken over, to be arranged in the outside of the outer tube of directly buried compensation device；A heat preservation left side take over a left side take between, the heat preservation right side take over the equal filled polyurethane foaming between outer tube, the left end of the left right end and thermal-insulation coat pipe taken over of heat preservation is integrally fixed, the right end of thermal-insulation coat pipe is socketed in the outside of earth-retaining ring, and earth-retaining ring set is connected on the right outside taken over of heat preservation；A heat preservation left side, which is taken over and kept the temperature between the right side is taken over, is arranged rubber bellows, and centrifugally glass-wool is filled in rubber bellows and a left side between taking over.The utility model has the advantages that：Can be taken over a left side for directly buried compensation device and outer tube and do corresponding axial movement, and fill centrifugally glass-wool between thermal-insulation coat pipe and directly buried compensation device, therefore, the rupture of insulating layer will not be formed, heat insulation effect is good.
Description
Technical field
The utility model is related to heat power equipment technical field, specifically a kind of compensator is more specifically a kind of compensation
The insulation construction of device.
Background technology
Compensator is essential component in heat transfer pipeline, the change for adjusting the duct length that temperature band is come
Change, ensures the normal work of pipeline.To ensure that temperature will not be lost in, the outside setting insulation construction of pipeline, and existing direct-burried
Insulation construction on the outside of compensator is typically only wound in a cavity with polypropylene material, and foaming material is then injected in cavity
Material, the structure cannot change with the variation of compensator, and therefore, foaming layer, which is torn, after compensator work can form gap, and
Underground water immerses the outside of compensator with the gap, not only has action of rust to compensator, but also can be by foaming layer insulation construction
It corrodes, causes the loss of heat.
Invention content
In order to solve the above-mentioned technical problem, what the purpose of this utility model was to provide a kind of sealing structure is directed to directly buried compensation
The insulation construction of device, specific technical solution are as follows：
A kind of directly buried compensation device sealing thermal insulation structure, a heat preservation left side is taken over, thermal-insulation coat pipe is arranged on a left side for directly buried compensation device
Outside is taken over, the heat preservation right side, which is taken over, to be arranged in the outside of the outer tube of directly buried compensation device；A heat preservation left side take over a left side take between, heat preservation it is right
The equal filled polyurethane foaming between outer tube is taken over, the left end of the left right end and thermal-insulation coat pipe taken over of heat preservation is integrally fixed,
The right end of thermal-insulation coat pipe is socketed in the outside of earth-retaining ring, and earth-retaining ring set is connected on the right outside taken over of heat preservation；Heat preservation a left side take over
Rubber bellows are arranged between taking in the heat preservation right side, and centrifugally glass-wool is filled in rubber bellows and a left side between taking over.
Multigroup groove is arranged in the outside of the earth-retaining ring.
The utility model has the advantages that：Can be taken over a left side for directly buried compensation device and outer tube and do corresponding axial movement,
And centrifugally glass-wool is filled between thermal-insulation coat pipe and directly buried compensation device, rubber bellows are arranged in the outside of mineral wool, therefore, can shape
At the heat insulation layer structure of the insulating layer of sealing, heat insulation effect is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is illustrated below in conjunction with the accompanying drawings, as shown in Figure 1, heat preservation left side take over 2, thermal-insulation coat pipe 3 are arranged
In 10 outside of left side take over of directly buried compensation device, keeps the temperature right take over 8 and be arranged in the outside of the outer tube 9 of directly buried compensation device；Heat preservation is left
Between take over 2 and left side take over 10, filled polyurethane foaming 1 between heat preservation right side take over 8 and outer tube 9, keep the temperature the right end of left take over 2 with
The left end of thermal-insulation coat pipe 3 is integrally fixed, and the right end of thermal-insulation coat pipe 3 is socketed in the outside of earth-retaining ring 6, and earth-retaining ring 6 is socketed
The outside of take over 8 on the heat preservation right side；Keep the temperature left side take over 2 and heat preservation right side take over 8 between be arranged rubber bellows 5, rubber bellows 5 with
Centrifugally glass-wool 4 is filled between left side take over 10.
Multigroup groove 61 is arranged in the outside of the earth-retaining ring 6, which can utilize mud by earth-retaining ring 6 and thermal-insulation coat pipe
3 gap is filled up.
Claims (2)
