Description
Technical field
The invention belongs to pipe element technical field, and in particular to a kind of pipeline insulating joint, applied to gas transmission and distribution
In pipeline and petroleum transportation pipeline, by between the pipeline of finite length implement be dielectrically separated from connection formed according to need length gas transmission,
Petroleum pipeline.
Background technology
It is no lack of the technical information on pipeline insulating joint, such as CN201884836U in disclosed Chinese patent literature
(Integral-type insulating joint)、CN2586861Y(Integral-type insulating joint)、CN2634240Y(Insulating joint)、CN2687466Y
(Insulating joint)、CN101994886A(Integral-type insulating joint)And CN102865423A(Pipeline Integral-type insulating joint),
Etc..
Typical " insulating joint of pipeline " recommended such as CN103438307A, its pipeline includes upstream conduit and downstream
Conduit, upstream conduit is constituted towards one end of downstream conduit a upstream conduit flange, and downstream conduit is towards upstream conduit
One end, which is constituted, a downstream tremie method orchid, and its insulating joint includes sleeve, insulator spacer(Patent claims " being dielectrically separated from pad ")With
Insulated dottle pin, and one end of sleeve is fixedly connected with upstream conduit flange(Welding), the middle part of sleeve is outer with downstream conduit flange
Wall is corresponding(Space between the two is configured to discharge cavity), and constituted between the other end of sleeve and the outer wall of downstream conduit exhausted
Edge is sealed, and insulator spacer is arranged between the side faced each other of upstream and downstream conduit flange, and insulation dottle pin is arranged on down
Trip conduit flange and sleeve are dielectrically separated between mating surface.
Although above-mentioned CN103438307A can cash the technique effect described in the technique effect column of its specification,
There is following shortcoming:First, the shim-like structure being integral due to insulator spacer, thus it is yielding when by extruding bending
And influence to be dielectrically separated from performance;Second, because coordinated insulation separator is by the end face of upstream conduit flange and downstream conduit flange
Between the seal that is dielectrically separated from be respectively that one of O-ring seal in the O-ring seal of an O-ring seal, i.e., two is located at
Between the end face of upstream conduit flange and the side for being dielectrically separated from pad, and another O-ring seal position in two O-ring seals
In downstream conduit flange end face and be dielectrically separated from pad opposite side between, thus two O-ring seals despite the use of, but by
It is limited in the sealing area of O-ring seal, i.e., because sealing surface is small, there is the anxiety of leakage;Third, due to insulator spacer direction
The position of the side of effective discharging gap is in unlimited fragile state, thus when upstream and downstream conduit is by even micro- vast
Bending when, easily cause insulator spacer to deform, cause leakage;Fourth, due to sleeve middle part and downstream conduit flange it is outer
Space between wall is configured to foregoing effective discharging gap, thus does not seal, so as to equally increase the several of leakage
Rate.In view of the foregoing shortcoming being not limited to, it is necessary to improved, technical scheme described below is in this background
Lower generation.
