Abstract
An insulation joint, used at a pipeline for petroleum, natural gas and chemical product, essentially comprises an irregular insulation bushing, a connection ring and a seal insulation ring and a seal ring which are all sandwiched between the irregular insulation bushing and the connection ring. The technic proposal is characterized in that: A seal groove is respectively equipped at the irregular insulation bushing and the connection ring which respectively correspond to two sides of the seal insulation ring. The seal groove being processed at the irregular insulation bushing and the connection ring can relatively increase the strength of the seal insulation ring, extend its service life and at the same time make a more reliable seal and a more convenient installation.
Description
Technical field:
The utility model relates to a kind of ducted insulating joints such as oil, rock gas, chemical industry that are used for.
Background technique:
At present, in pipelines such as oil, rock gas, chemical industry widely used insulating joint its put on two faces of seal groove processing at the sealed insulation ring of seal ring, make the intensity of sealing dead ring reduce like this, easily cause this dead ring to damage, and the working life of reducing insulating joint thus.In addition, the installation of this kind structure is also not too convenient.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of reliable operation, long service life and insulating joint easy for installation.
The purpose of this utility model is to realize like this, it mainly comprise allotype insulation cover, connecting ring and place allotype insulation cover and connecting ring between sealed insulation ring and seal ring, it is characterized in that: the seal groove branch of putting seal ring is located on the allotype insulation cover and connecting ring corresponding with sealed insulation ring two sides.
The utility model has the advantages that seal groove processing on allotype insulation cover and connecting ring, make it to increase relatively the intensity of sealed insulation ring, improve its working life, make sealing more reliable simultaneously, install more convenient.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
By accompanying drawing as can be known, the utility model is made of allotype insulation cover 2, connecting ring 5, sealed insulation ring 3,4, seal ring 8, cylinder sleeve 1 and meropodium 6, pipe nipple 7.Sealed insulation ring 3 places between allotype insulation cover 2 and the connecting ring 5, and two seals circle 8 is located at respectively in the seal groove that allotype insulation cover 2 and connecting ring 5 processed; Sealed insulation ring 4 places between cylinder sleeve 1 and the allotype insulation cover 2; Cylinder sleeve 1 is that the outside of insulating joint connects metalwork, with connecting ring 5 welding; Meropodium 6 and pipe nipple 7 weld with allotype insulation cover 2 and connecting ring 5 respectively.The other end of meropodium 6 and pipe nipple 7 is connected with pipeline respectively in actual the use, is reliably insulated in the two ends of insulating joint.
