Abstract
The utility model discloses a kind of New insulated joint, including the left male flange and right male flange being connected respectively with short tube, the first dead ring and seal are set between left male flange and right male flange；Insulating packing is set between fixed cover and right male flange；The weld seam of short tube and right male flange is located at outside fixed cover；Second dead ring is set between fixed cover and right male flange；Insulating packing is set between fixed cover, the second dead ring and right male flange.Compared with prior art, the utility model has the advantages that：Left and right flange uses overall structure, calculated by standard clip model, add the bending resistance of product, sealing structure is sealed using " U " type or " U+O " type, add the ability of product resistance to deformation, short tube is located at outside fixed cover with right flange weld seam, is convenient for Non-Destructive Testing, it is ensured that the security reliability of welding point.Both it can guarantee that safe and reliable, electrical insulation capability can guarantee that again.
Description
Technical field
The utility model is related to a kind of electric insulation arrangement for pipeline cathode protection system, is particularly suitable for use in oil-gas transportation
Pipeline.
Background technology
Pipeline cathode protection system, can effectively prevent corrosive pipeline, insulating joint is as in pipeline cathode protection system
A critical piece, main function be by insulating joint two ends pipeline electric insulation, prevent the loss of cathodic protection road electric current, carry
High pipeline cathode protection effect, both requires sealed reliable, requires that electrical insulation capability is good again.
But it is due to that insulating joint product quality is uneven, particularly recent years, in puckery peaceful blue, middle remote line, middle expensive
Occurs extensive insulation joint seepage accident on the long distance pipelines such as line.Not only seriously restrict the throughput rate of whole gas distributing system, shadow
Ring country's production and people's lives；Also there is huge potential safety hazard, great economic loss and serious social risk.By
Analysis investigation shows that existing insulating flange flange uses bell and spigot frame, is calculated by flange model；Sealing encloses sealing using " O ", leads
Product bending resistance is caused to decline；In addition short tube is located on the inside of fixed cover with right flange weld seam, is difficult to carry out Non-Destructive Testing；So as to
Cause insulating joint that there is larger potential safety hazard and disclosure risk, the sealing of influence product and performance.
Utility model content
The utility model overcomes shortcoming of the prior art there is provided a kind of New insulated joint, is a kind of entire card
Bind round connecting-type, using " U " type or the sealed insulating joint of " U+O " type, both can guarantee that safe and reliable, electrical insulating property is can guarantee that again
Energy.
The technical solution of the utility model is：A kind of New insulated joint, including the left flange method being connected respectively with short tube
Blue and right male flange, sets the first dead ring and seal between left male flange and right male flange, in left flange method
Fixed cover is set outside blue, right male flange and seal.
Further, left male flange and right male flange with short tube butt welding.
Further, seal is " U " type or " U+O " type sealing structure.
Further, insulating packing is set between fixed cover and right male flange.
Further, fixed cover and left male flange after applying assembling pretightning force by welding.
Further, the weld seam of short tube and right male flange is located at outside fixed cover.
Further, the second dead ring is set between fixed cover and right male flange.
Further, insulating packing is set between fixed cover, the second dead ring and right male flange.
Compared with prior art, the utility model has the advantages that：Left and right flange uses overall structure, by standard clip mould
Type is calculated, and adds the bending resistance of product, and sealing structure is sealed using " U " type or " U+O " type, adds product resistance to deformation
Ability, short tube and right flange weld seam be located at outside fixed cover, is convenient for Non-Destructive Testing, it is ensured that welding point it is safe and reliable
Property.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of New insulated joint, as shown in figure 1, including：Short tube 1, left male flange 2, the first dead ring 3, second are exhausted
Edge ring 4, seal 5, fixed cover 6, insulating packing 7, right male flange 8, short tube 9 etc., wherein：
Center-aisle is high-pressure fluid.Left male flange 2 and right male flange 8 use overall structure, short tube 1, short tube 9
Respectively butt welding is used with left male flange 2, right male flange 8；Seal 5 is " U " type or " U+O " type sealing structure, is put
Between left male flange 2 and right male flange 8, sealing is realized by the pretightning force that fixed cover 6 applies, pipeline inner high voltage is prevented
Fluid is leaked；Fixed cover 6 and left male flange 2 after applying assembling pretightning force by welding, and short tube 9 is located at right flange weld seam
Outside fixed cover, insulating packing 7 is filled between fixed cover 6 and right male flange 8 in gap；Second dead ring 4 and the first dead ring 3
Left male flange 2 and right male flange 8 are realized by electric insulation by fixed cover 6 and insulating packing 7.Short tube 1,9 in product use
The other end respectively with pipeline welding.
Claims (6)
1. a kind of New insulated joint, it is characterised in that：Including the left male flange and right male flange being connected respectively with short tube,
