Abstract

The utility model discloses a combined type direct-buried telescopic compensator which is formed by the weld of the compensator of a sleeve barrel through a combination seal (5). The periphery of a connecting body is totally provided with a heat-insulating layer (1), a casing (4) and a protecting pipe (6) which plays the role of a protecting sleeve; a corrugated pipe (8) is made of non-metal materials. A corrugated pipe (3) and a telescopic pipe (7) jointly realize the compensation and the absorption of the quantities of heat expansion and cold contraction in a pipeline.

Description

Combined type direct-burried telescopic compensator
Technical field the utility model is the device about pipeline compensator, especially the device of heat distribution pipeline compensation or the absorption direct-burried pipeline section amount of expanding with heat and contract with cold.
Background technique is present, existing compensator is the compensator of single type, simple structure, in case occur leaking, whole compensator can not deaden the sealing surface that underground water and sand enter compensator effectively, must set up inspection shaft, uneconomical inconvenience can't be provided with the maintenance overhaul well especially in the concentrated supply of heating in the city pipeline.
Summary of the invention the utility model has overcome deficiency of the prior art, provides a kind of and has been combined into selfsealings and multi-sealed directly buried type does not have the support compensator by corrugated expansion joint and sleeve expansion joint.
The utility model adopts following technical proposal:
Corrugated expansion joint and sleeve expansion joint are connected together by welding, established thermal insulation layer altogether, and the bellows in the sleeve expansion joint is that non-metallic material is made in the periphery of connecting body.
Owing to adopted technique scheme, the compensator that the utility model provides has such effect, it is the sealing surface that underground water and sand are difficult for entering compensator, when leaking appears in connecting body a part, sleeve expansion joint plays multi-sealed effect, undulator has compensated self sealing action, thereby has prolonged the working life of compensator, and does not undergroundly need to establish the maintenance overhaul well.
Appended drawings is a structure principle chart of the present utility model.
Among the figure: thermal insulation layer 1 honeycomb duct 2 bellowss 3 housings 4 combination seals 5 pillars 6 telescopic pipes 7 bellowss 8
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Combination seal 5 links together corrugated expansion joint and sleeve expansion joint; housing 4 and pillar 6 play the protecting jacket effect; they by bellows 3 and telescopic pipe 7 realize compensating with extraction duct in the amount of expanding with heat and contract with cold; honeycomb duct 2 play the guiding role; prevent that bellows is subjected to external force effect bending deflection, whole connecting body periphery is provided with thermal insulation layer 1, in case heat dissipation in the pipeline; bellows 8 is made by nonmetallic material, in case the corrosivity of high salt area water.

Claims (4)

1, a kind of combined type direct-burried telescopic compensator, it comprises thermal insulation layer (1), bellows (3), honeycomb duct (2), combination seal (5), pillar (6), housing (4), telescopic pipe (7), bellows (8) is characterized in that combination seal (5) links into an integrated entity corrugated expansion joint and sleeve expansion joint.
2, compensator as claimed in claim 1 it is characterized in that described bellows (8) made by non-metallic material, and the outside is provided with pillar (6).
3, compensator as claimed in claim 1 is characterized in that described combination seal (5) is composited for multi-sealed and self sealing structure.
4, compensator as claimed in claim 1 is characterized in that described connecting body periphery established thermal insulation layer (1) altogether.
