Description
Technical field
The utility model is related to pipe safety devices, particularly relate to a kind of bidirectional direct-buried heat preservation water supply sleeve expansion joint.
Background technology
Direct-buried sleeve compensator is also known as tubular type telescopic joint, is the compensation device of hot fluid pipeline, is mainly used at home
Rectilinear duct additionally arranges.Belong to a kind of benefit being directly installed among any pipeline for conveying free from corrosion unidirectional or multidirectional fluid
Repay device.Most common plain edition sleeve expansion joint just makes always early in the sixties in last century in direct-buried sleeve compensator
With ordinary cartridge compensator is simple, and compensation rate is limited, can only one direction installation；Existing compensator of straight-embedded socket heat preservation
Using the Totally enclosed heat-preserving mode identical with straight tube, when compensator is run, keeping warmth space is compressed, and polyurethane foam can expand
Outer protection tube, groundwater erosion sleeve expansion joint and hot water pipeline are damaged, causes insulation construction loss of function.
Utility model content
The utility model discloses a kind of bidirectional direct-burieds to keep the temperature water supply sleeve expansion joint, can realize bidirectional compensating, compensates
Amount is big, and heat preservation and sealing effect are good.
The utility model is achieved through the following technical solutions：
A kind of bidirectional direct-buried keeps the temperature water supply sleeve expansion joint, including gland, sealing ring, filler, bellows, protection
Set, linkage tube, heat-preservation cotton, pipe nipple, the pipe nipple is equipped with the gland, between the gland and protective case
Equipped with the sealing ring, the filler is equipped between the sealing ring and gland, is equipped among the protective case described
Dynamic pipe, linkage tube both sides are equipped with the bellows, and the bellows is connected respectively with the pipe nipple, and the bellows lower end is set
There is the heat-preservation cotton.
Preferably, the gland is equipped with fastening bolt.
Preferably, the bellows is connected by cuff with the pipe nipple.
Compared with prior art, the beneficial effects of the utility model are：
1st, the heat preservation of the utility model and sealing effect are good, and at the scene without special process in installation process, installation is simply；
2nd, the bi-bellow linkage compensation of the utility model, realizes structure-integrated, and linkage is reliable, operates steadily, has
It is run beneficial to mating network security；
3rd, the utility model is bilateral symmetry, two-way can be installed, and compensation rate is big, one i.e. alternative original two
It is a, installation effectiveness is effectively increased, has saved installation cost.
Description of the drawings
Fig. 1 is the sectional view of the utility model.
In figure：1st, gland；2nd, sealing ring；3rd, filler；4th, bellows；5th, protective case；6th, linkage tube；7th, heat-preservation cotton；
8th, pipe nipple.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of bidirectional direct-buried keeps the temperature water supply sleeve expansion joint, including gland 1, sealing ring 2, filler 3, bellows 4, guarantor
Sheath 5, linkage tube 6, heat-preservation cotton 7, pipe nipple 8, the pipe nipple 8 be equipped with the gland 1, the gland 1 with
The sealing ring 2 is equipped between protective case 5, the filler 3, the protective case are equipped between the sealing ring 2 and gland 1
Be equipped with the linkage tube 6 among 5,6 both sides of linkage tube are equipped with the bellows 4, the bellows 4 respectively with the pipe nipple 8
It is connected, 4 lower end of bellows is equipped with the heat-preservation cotton 7.
The gland 1 is equipped with fastening bolt.
The bellows 4 is connected by cuff with the pipe nipple 8.
When the instrumentation tubes generation displacement of compensator, the bellows 4 can freely stretch, and the bellows 4 is internally provided with
The heat-preservation cotton 7, to ensure that bellows heat-preservation cotton 7 when flexible has certain flexible deformation.
The above only expresses the embodiment of the utility model, and description is more specific and in detail, but can not be because
This and be interpreted as the limitation to the utility model patent scope, within the spirit and principle of the utility model, made appoint
What modification, equivalent substitution, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent
Shield scope should be determined by the appended claims.
