Technical field
The utility model relates to the seal for pipe joints technical field, specifically the quick repairing device of elbow.
Background technique
Continuous development along with modernized oilfield construction, various petroleum pipelines are on the increase, but along with the continuous growth of life time, pipeline corrosion, the pipeline thorn that reasons such as quality cause leaks, fracture often occurs, traditional solution is exactly to stop production comprehensively, and welding leaks outside, and is not only time-consuming but also take a lot of work, and in the oil field gathering and transportation zone, get angry, have major accident hidden danger.If the corrosion leakage position is not protected, cause external pressure that corrosion place is beaten easily and come off, cause bigger leakage, perhaps sealer is squeezed into pipeline inside, can't play seal action.
The model utility content
In order when petroleum pipeline leaks petroleum pipeline to be keeped in repair, the utility model provides a kind of elbow quick repairing device.
The purpose of this utility model is come specific implementation by the following technical programs:
The quick repairing device of elbow, comprise elbow main body, otic placode and rubber injecting valve, described elbow main body is installed on the otic placode, the edge of described otic placode is provided with a plurality of attachment holes, described elbow main body has the curved injecting glue storehouse of indent, be provided with a plurality of hole for injecting glue in the inside of described elbow main body, corresponding each hole for injecting glue is provided with gum-injecting port at otic placode, and each described gum-injecting port is connected with a rubber injecting valve.
Described otic placode is the fan-shaped of 90 degree, and the area of otic placode is greater than the area of elbow main body.
The cross sectional area of described gum-injecting port is greater than the cross sectional area of described hole for injecting glue.
The quick repairing device of elbow described in the utility model flexibly connects rear stability, reliability and strengthens, and more in light weight 25% than flange, volume reduces 20%, and noise reduces 40%-60%.It is convenient that pipeline connects construction, and reliable, safety can realize that the tubing of different wall connects, and the product surface material can prevent outside impingement attack, and the repairing pipe non-stop plugging, exempts to get angry fast and reliable, is fit to the repairing that leak at the channel bend place.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural drawing of the quick repairing device of the described elbow of the utility model embodiment.
Fig. 2 is the sectional structure chart of the quick repairing device of the described elbow of the utility model embodiment.
Fig. 3 is the structural drawing of rubber injecting valve.
Embodiment
As Figure 1-3, the quick repairing device of the described elbow of the utility model embodiment, comprise elbow main body 1, otic placode 2 and rubber injecting valve, described elbow main body 1 is installed on the otic placode 2, the edge of described otic placode 2 is provided with a plurality of attachment holes 21, and described elbow main body 1 has the curved injecting glue storehouse 11 of indent, is provided with a plurality of hole for injecting glue 12 in the inside of described elbow main body 1, corresponding each hole for injecting glue 12 is provided with gum-injecting port 22 at otic placode, and each described gum-injecting port 22 is connected with a rubber injecting valve.
Described otic placode 2 is the fan-shaped of 90 degree, and the area of otic placode 2 is greater than the area of elbow main body 1.
The cross sectional area of described gum-injecting port 22 is greater than the cross sectional area of described hole for injecting glue.
The beneficial effects of the utility model are:
1. safe and reliable, good airproof performance: novel connector and repairing device, can withstand voltage 2.5Mpa, 100 ℃ of heatproofs, specific (special) requirements can withstand voltage 3.2Mpa, is fit to the above piping of 80 % on (thick rare) oil processing station.The seal ring pressure is significantly less than its limit of elasticity, pretightening force only is 2 kilograms/square centimeter, far below flange gasket, its pretightening force reaches 70 kilograms/square centimeter, and balancing orifice has guaranteed that seal action is directly proportional with loine pressure, therefore can reach durable, the requirement that continues reliable sealing for a long time, be difficult for producing " three leak " phenomenon, its life-span was the Applicable scope Nei Keda of regulation 20～30 years.
2. antidetonation, anti-impact, noise reduction: this connector, repairing device have changed traditional being rigidly connected and have been flexible connection, make piping be in that anti-impact is shaken, the state of eliminated noise.This connector, repairing device itself can anti-0.02 second in the acceleration of 350g impact, compare with the flange mode, noise intensity can reduce by 80 %, is conducive to whole piping, comprises that safety such as pump, valve, instrument are normal to use life-saving.
3. alleviate piping weight: but compare about 75 % of loss of weight with the flange mode.
4. save the pipeline space: mounting or dismounting need not flanged full phase construction, only twist bolt from a side chain, thereby can save line arrangement and construction space reaches 50 %, and the naval vessel reasonable disposition piping limited to the space is significant.Flexible connection allows 10 ° of two tubular axis line alternate angles, 6 ° of single tube deviation angles, the pipe end spacing can reach 5～35mm etc., and loose tolerance range has been avoided the highi degree of accuracy matching requirements, is conducive to shipbuilding industry and promotes advanced technologies structural measures such as complete cross section construction and " buoyant raft " vibration insulation and noise reduction.Cause that in shipbuilding installation deviation or ship navigation skew all has no adverse effects to pipe jointer, repairing device.
5. compatible adaptability is good: this connector, repairing device are widely used in various metal tubes and composite material tube, both can be used for same material, also can be used for different material, connected between the pipeline, to the wall thickness of its pipe that is connected, and connect end face etc. and all do not have too high processing request.
6. make things convenient for fast-assembling: during site operation, connector, repairing device itself need not assembling, and the pipeline that is connected does not have loaded down with trivial details adjustment processing request yet, only needs torque spanner moment of torsion in accordance with regulations to tighten 2～3 bolts from a side during installation, operates easy especially.
7. easy to maintenance: as when repairing pipeline, even the profit state is arranged in the pipe, need not heat because welding also, and not having fire, two clips, opening type, collapsible repairing device are used in without explosion danger, can adopt the wrapping mode to rush to repair from various damaged pipelines outside.
8. cost performance is higher: this connector, repairing device operating expenses, and than flange saving, though single cost is slightly higher than general flange price, its long service life, cost performance is higher.And on corronil and stainless steel pipeline, single cost is lower than or approaches, middle caliber, corronil flange and steel flange.
9. be convenient to computer-aided design: owing to needn't consider hole circle week etc. of flange plate, more simple and direct with computer-aided design, pipeline flow chart etc. is simplified in promotional module design easily, reduces the design and construction expense.
