Description
Technical field
The utility model is related to a kind of insulating joint more particularly to a kind of combustion gas insulating joints.
Background technology
In the insulation such as combustion gas, the higher pipeline application of sealing performance, insulating joint can meet transmission ＆ distribution pipeline requirements simultaneously
Good seal performance, the good insulation preformance required by intensity is high and electrical anticorrosion, be essential heavy in transmission ＆ distribution pipeline system
Pressure elements is wanted, so it is very necessary to configure insulating joint between burning line section pipe, it is ensured that it is used safely.
Insulating joint used at present is vulnerable to the effect expanded with heat and contract with cold or pipe sedimentation so that insulating joint is under pressure
Lead to gas leakage, and since gas transmission and distribution pipe installation is in underground, is vulnerable to broken by lightning.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide the simple in structure, good airproof performance of one kind and can avoid pipe
The combustion gas insulating joint that road is damaged by lightning stroke.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of combustion gas insulating joint, including
First flange, second flange, insulation spacer, dead ring, fixed plate, the second flange, dead ring, fixed plate are fitted to first
In flange, the insulation spacer, dead ring pad the both sides of the face loaded on second flange respectively, and the fixed plate press fitting is in dead ring
Right end face, sealing ring is provided between the opposite end wall of the first flange, second flange, outside the first flange circumference
Cavity is formed between portion and second flange circumferential inner, gasket seal is equipped between the cavity and dead ring, described first
Flange is socketed an insulation sleeve with the external of fixed plate press fitting, and locating ring is equipped at the insulation sleeve port.
Further, the locating ring includes snap ring, the snap ring and insulation sleeve fixed seal connection.
Further, the first flange and the second flange are connected with the first short tube and the second short tube respectively.
Further, the material of the insulation spacer be epoxy novolac fabric swatch or epoxy laminate, and thickness be more than or
Equal to 10mm.
Further, epoxy resin sealant is filled between the second flange outer tube surface and fixed plate.
The utility model has the advantage of：
A kind of combustion gas insulating joint of the utility model is by using multistage denses such as insulation sleeve, dead ring, gasket seals
Envelope mode, it can greatly improve the leak-tight seal performance of insulating joint, and insulating joint can be avoided by expanding with heat and contract with cold
Effect or pipe sedimentation and lead to gas leakage, while outer being sleeved on first flange and can effectively be kept away with the insulation sleeve outside fixed plate
Exempt to be struck by lightning.
