Abstract
The utility model relates to a compensation apparatus with direct-buried sleeves, which comprises an inner sleeve and an outer sleeve. The utility model is characterized in that a telescope pipe is welded on one end of the outer sleeve, an anti-run shoulder is connected on the other end, and the seal groove of the inner sleeve is decorated with a V-shaped knitted fabric rubber packing ring. The utility model has the advantages that the highest working pressure reaches 500 mega Pascal, and bears better conducting and seal effect, which can cancel the anchorage. The utility model is safe and reliable, which greatly reduces construction cost, simultaneously improves service life of the product, and reduces construction and maintenance cost.
Description
Technical field
This novel a kind of heat distribution pipeline bearing compensation device, particularly a kind of direct-burried sleeve expansion joint of belonging to.
Background technique
On heat distribution pipeline, for the heat that compensates pipeline is stretched, employing is the installing sleeve compensator on heat distribution pipeline, sleeve expansion joint is in the past generally taked packing seal on sealing configuration, but stuffing box packing is leaked, and makes the maintenance of product very loaded down with trivial details, also increased engineering cost, and special inspection shaft must be set under ground piping, and the general pipeline that sleeve expansion joint is set also need be provided with fixed bearing, and these have increased engineering cost greatly.
The model utility content
The purpose of the utility model content provides a kind of direct-burried sleeve expansion joint, has good steering capability and sealability, and safe and reliable, engineering cost is low.
The purpose of the utility model content is achieved by the following technical solution: it comprises inner sleeve, outer sleeve, it is characterized in that: at overcoat one end welding reducer pipe, connect the anticreep shoulder at the other end, installing V-arrangement folder fabric rubber seal in the seal groove on inner sleeve is provided with twice ovaloid seal circle respectively in the seal groove of the both sides of V-arrangement folder fabric rubber seal.
The utility model has the advantages that: 1, V-arrangement folder fabric rubber seal more is applicable to liquid medium, and Maximum operating pressure can reach 50Mpa.2, the effect that not only can play again insurance of this twice ovaloid seal circle makes the better guidance quality that has between inside and outside sleeve again, prevents off-centre and influences sealing effect.Since the ovaloid seal circle have connect the more common round section joint ring of true area to connect true area bigger, so it has better guiding and sealability.3, fix with safetied pin between anticreep shoulder and outer sleeve, the pressure thrust that can bear pipeline between the boss of anticreep shoulder and inner sleeve can fully phase out fixed bearing on the pipeline.4, on inner sleeve and anticreep shoulder, all be provided with the native felt of retaining, when preventing to bury ground in introduced contaminants and the pipeline impurity destruction of sealing surface has been guaranteed that effectively product safety works reliably.5, significantly reduced engineering cost, also improved the working life of product and reduced the engineering maintenance expense simultaneously.The utility model is provided with Earthguard cover when installing outside outer sleeve and inner sleeve, soil when burying ground like this and insulation just can not destroy the proper functioning of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, concrete structure is as follows: at outer sleeve 7 one ends welding reducer pipe 8, pass through fixedly anticreep shoulder 2 of safetied pin 3 at the other end.Installing V-arrangement folder fabric rubber seal 6 in the seal groove on inner sleeve 1, the rubber part of rubber seal 6 adopts the better fluorine rubber of heatproof to make.In the seal groove of the both sides of V-arrangement folder fabric rubber seal 6, twice ovaloid seal circle 5 is set respectively.On end of inner sleeve 1 and anticreep shoulder 2, all be provided with the native felt 4 of retaining, outside outer sleeve 7 and inner sleeve 1, Earthguard cover be set when the utility model is installed.
