Large-scale pipeline sealing cover assembly generally comprises pipeline body and sealing cover at present, one end cylindrical of pipeline body is provided with outside thread, the inner circle of sealing cover is provided with internal thread, the end face being threaded between seal body and sealing cover is provided with the seal ring for sealing, and seal ring is generally rubber, makes.The large-scale pipeline sealing cover assembly of prior art is when seal body and sealing cover screw, and the frictional force of sealing cover and seal ring is large, is difficult for compressing and may causes infiltration or leak.Also have a kind of situation, after compression, after long-term use, sealing cover is likely loosening with pipeline body, thereby causes leaking.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of and easily screws and good sealing effect, prevent that sealing is stamped with pipeline body looseningly, avoids the large-scale pipeline sealing cover assembly leaking.
The technical solution of the utility model is, a kind of large-scale pipeline sealing cover assembly with following structure is provided, comprise pipeline body and sealing cover, the end of described pipeline body is provided with outside thread, the endoporus of described sealing cover is provided with the internal thread that the outside thread with pipeline body screws, described sealing cover screws the end at pipeline body, between the exterior edge face of described pipeline body and the interior edge face of sealing cover, be provided with Gask-O-Seal, the end face of described Gask-O-Seal is provided with ring shaped axial projection, the interior edge face of described sealing cover is provided with the first ring connected in star embedding for ring shaped axial projection, the bottom surface of described Gask-O-Seal is provided with several annular pointed projections, the end face of described pipeline body is the pointed groove of annular meshing one by one with the pointed projection of annular.
The sidewall of described sealing cover is combined with Cock screw, and the tube wall of described pipeline body is provided with the second annular groove, and the tail end of described Cock screw is embedded in the second annular groove.
The head of described Cock screw is positioned at the through hole of the sidewall of described sealing cover.
Adopt after above structure, the utility model compared with prior art, have the following advantages: owing to being provided with Gask-O-Seal between the exterior edge face of described pipeline body and the interior edge face of sealing cover, when screwing, make like this sealing cover contact with seal ring by packing ring, reduced the frictional force between sealing cover and seal ring, be conducive to sealing cover and seal body and screw completely and good sealing effect.Again owing to being provided with Gask-O-Seal between the exterior edge face of described pipeline body and the interior edge face of sealing cover, the end face of described Gask-O-Seal is provided with ring shaped axial projection, the interior edge face of described sealing cover is provided with the first ring connected in star embedding for ring shaped axial projection, after ring shaped axial projection coordinates with first ring connected in star tabling like this, prevent that Gask-O-Seal from radially sliding; Bottom surface due to described Gask-O-Seal is provided with several annular pointed projections again, and the end face of described pipeline body is the pointed groove of annular meshing one by one with the pointed projection of annular, increases area of contact, and sealing effect is better.
As improvement, the sidewall of described sealing cover is combined with Cock screw, and the tube wall of described pipeline body is provided with the second annular groove, and the tail end of described Cock screw is embedded in the second annular groove, prevents that sealing cover is loosening outwards mobile.
As improvement, the head of described Cock screw is positioned at the through hole of the sidewall of described sealing cover, and the user's that prevents from swiping hand increases Security.
