Abstract
The utility model belongs to a pressure pipeline element, and discloses a direct buried sleeve compensator mainly used for compensating axial expansion and radial rotation of a pipeline. The body of the direct buried sleeve compensator consists of an inner sleeve, an outer sleeve and a tensile flange. The direct buried sleeve compensator is characterized in that: a combined seal consisting of a Y-shaped sealing ring and two O-shaped sealing rings is arranged at the cross part of the inner sleeve and the outer sleeve, and tensile function is realized through the tensile flange. The direct buried sleeve compensator has the characteristics of safe and reliable working performance, long service life and the like.
Description
Technical field
The utility model belongs to the pressure piping element, is mainly used in the axial stretching of compensation pipeline and rotation radially.
Background technique
Because factors such as the difference variation of working medium and alignment error have caused pipeline axial flexible and radially reverse, flexible and radially reverse for eliminating pipeline axial, material filling type compensator or corrugated expansion joint are installed in pipeline usually.Because the material filling type compensator needs the regular replenishment filler, so under ground piping, must be provided with special maintenance well, has improved engineering cost, has increased maintenance cost; The stainless steel of corrugated expansion joint has aggravated corrosion because of chloride ion content in the fed sheet of a media, thereby explosion takes place, and is prone to take place major accident and causes a large amount of economic losses.
Summary of the invention
It is safe and reliable that the purpose of the utility model just provides a kind of service behaviour, the direct-burried sleeve expansion joint of long service life.
The technological scheme that adopts:
The direct-burried sleeve expansion joint comprises outer sleeve, anti-flange and the inner sleeve broken.It is characterized in that being provided with successively on the outer wall of head of described inner sleeve one y-type seal ring and twice 0 RunddichtringO; The outer cover of described outer sleeve is equipped with the anti-flange of breaking.
The major advantage of the utility model:
1, service behaviour is safe and reliable:
The head first road y-type seal ring of inner sleeve relies on self-pressure type motive sealing principle to guarantee reliable motive sealing performance; Twice O RunddichtringO has played the effect of supporting and prevent outside dirt; The outer sleeve combination prevents that breaking flange has prevented that inner sleeve from pulling out, and guaranteed safety.
2. reduced construction cost
Because the utility model is reasonable in design; Service behaviour is safe and reliable, and reaches working life more than 10 years, therefore can remove the maintenance well of special setting from; Can reduce engineering cost greatly, be used for the conveyance conduit of industries such as cities and towns heating, metallurgy, generating, petrochemical industry, building more easily.
Description of drawings
Figure l is the structural representation of the utility model.
Embodiment
The direct-burried sleeve expansion joint comprises outer sleeve 1, anti-flange 2 and the inner sleeve 3 broken.Be characterized in being provided with successively on the outer wall of head of inner sleeve 3 one y-type seal ring 4 and twice 0 RunddichtringO 5; The outer cover of outer sleeve 1 is equipped with the anti-flange 2 of breaking.
