Description
Technical field
The invention belongs to jet chimney technical fields, and in particular to the pipe cap of prefabricated steel bushing steel direct-buried steam insulation pipe.
Background technique
After the completion of polyurethane steel bushing steel direct-buried steam insulation pipe is prefabricated in the factory, the insulating layer of end will generally be used
Plastic foil, which closes, to be come, and when to prevent air storage, rainwater and dust enter, and traditional way is directly with plastic cloth and adhesive tape
It is wrapped in pipe end, during transportation, plastic cloth is easily damaged, and adhesive tape is also easy to lose viscosity, pipe content after drenching with rain
Easily water inlet.
Summary of the invention
To overcome the defects of present in the prior art, the present invention provides a kind of dedicated prefabricated steel bushing steel direct-buried steam insulation
The pipe cap of pipe is sealed packaging to pipe end.
The invention solves technical solutions used by its technical problem to be:
The excircle of the pipe cap of prefabricated steel bushing steel direct-buried steam insulation pipe, the cap body including circular ring shape, the cap body side connects
It is connected to the sleeve of annular, the sleeve is covered perpendicular to cap body, sleeve in prefabricated steel bushing steel direct-buried steam insulation tube end
On outer tube wall；Circular hole is equipped among the cap body, the outer diameter of circular hole is greater than the work of prefabricated steel bushing steel direct-buried steam insulation pipe
The outer diameter of core pipe, circular hole and cap body concentric；The bore edges set the sealing edge for fixing circle elasticity；The sealing edge
Internal diameter decrement, the one end being relatively large in diameter is fixedly connected with the bore edges of cap body, and the lesser one end of diameter is small running-on, described
The internal diameter of small running-on be less than the outer diameter of the work core pipe, the sealing edge and sleeve are located at the two sides of cap body.
Preferably, the sleeve lining is equipped with the raised line of annular, the raised line and sleeve coaxial inner conductor.
Further, set the auxiliary sealing strip of flexible annular on the inside of the sealing edge, the auxiliary sealing strip with it is close
Edge sealing coaxial inner conductor, the internal diameter decrement of auxiliary sealing strip, the one end being relatively large in diameter are fixedly connected with sealing edge inner wall, and diameter is lesser
One end is small secondary running-on, and the internal diameter of the small secondary running-on is less than the outer diameter of the work core pipe.
The present invention has the beneficial effects that
The pipe cap of prefabricated steel bushing steel direct-buried steam insulation pipe provided by the invention is hardly damaged pipe end seal protection,
It is not easy to effectively protect pipeline internal insulation structure into water.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention；
Fig. 2 is use state diagram of the invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Such as Fig. 1, the pipe cap of prefabricated steel bushing steel direct-buried steam insulation pipe, the cap body 1 including circular ring shape, 1 side of cap body
Excircle is connected with the sleeve 2 of annular, and the sleeve 2 is covered perpendicular to cap body 1, sleeve 2 in prefabricated steel bushing steel direct-buried steam
On the outer tube wall for keeping the temperature tube end；Circular hole is equipped among the cap body 1, the outer diameter of circular hole is greater than prefabricated steel bushing steel direct-buried steam
The outer diameter of the work core pipe of insulating tube, circular hole and 1 concentric of cap body；The bore edges set the sealing edge for fixing circle elasticity
3；The internal diameter of the sealing edge 3 reduces, and the one end being relatively large in diameter is fixedly connected with the bore edges of cap body 1, and diameter is lesser
One end is small running-on 6, and the internal diameter of the small running-on 6 is less than the outer diameter of the work core pipe, the sealing edge 3 and sleeve
2 are located at the two sides of cap body 1.
Pipe cap generally plastics are made, and have certain elasticity, and soft.
When use, as shown in Fig. 2, work core pipe is passed through from the circular hole of cap body 1, by 2 sets of sleeve in outer tube wall
On end, sealing edge 3 is elastic, therefore the small running-on 6 of sealing edge 3 is tightly attached on the outer wall of work core pipe, forms sealing ring.
For the fastening for ensuring sleeve 2,2 inner wall of sleeve is equipped with the raised line 4 of annular, and the raised line 4 and sleeve 2 are same
Axial line.Raised line 4 can have a plurality of, be arranged in parallel.
To prevent small running-on 6 from waiting frictional tear, and raising leakproofness during installation, it is equipped on the inside of the sealing edge 3
The internal diameter of the auxiliary sealing strip 5 of the annular of elasticity, the auxiliary sealing strip 5 and 3 coaxial inner conductor of sealing edge, auxiliary sealing strip reduces, directly
The biggish one end of diameter is fixedly connected with 3 inner wall of sealing edge, and the lesser one end of diameter is small secondary running-on, the small secondary running-on it is interior
Diameter is less than the outer diameter of the work core pipe.Auxiliary sealing strip 5 forms second sealing ring.
