The inwall that one steel cylinder is close to the first anticorrosive casing pipe is set, and the inner diameter values of second steel cylinder are identical with the inner diameter values of insulating inner tube,
And dead ring is equipped between the second steel cylinder and the insulating inner tube of its both sides, first steel cylinder, insulation tube and the second steel cylinder
Both ends of the both ends respectively with two dead rings offset.
Preferably, second anticorrosive casing pipe is made up of anti-corrosion outer tube and steel inner tube, and the steel inner tube is close to anti-corrosion outer tube
Inwall set, several spacing rings are evenly equipped with the outer wall of the steel inner tube, and spacing ring is integrally formed setting with steel inner tube.
Preferably, first anticorrosive casing pipe is integrally formed with anti-corrosion outer tube, and both at heat-shrink tube.
Preferably, the insulating inner tube, insulation tube and dead ring are made of PE insulating materials.
Compared with prior art, the beneficial effects of the utility model are：By being wrapped up in the junction of two gas steel pipelines
Heat-shrink tube, the corrosion resistance of joint design is greatly improved relative to existing courtyard heating pipe network mesolow lightning-protection connector so that should
Joint buried can both be installed, and can also be directly exposed to install in air；By between two steel pipes set inside and outside two layers of steel bushing,
And insulation tube is set between two layers of steel bushing, while both having ensure that the intensity of low-voltage insulation joint, also improve joint design
Insulating properties, effectively solve existing courtyard heating pipe network gas pipeline joint in industry and be unsuitable for being directly exposed to pacifying in air
The shortcomings that dress.
