Gas pipeline drainer horn mouth leakage-baffling device
Technical field
The utility model relates to gas pipe line maintenance field in metallurgy, chemical industry, refers to particularly a kind of gas pipeline drainer horn mouth leakage-baffling device.
Background technique
The special media pipe container leakage problems such as poisonous, inflammable, explosive, deep-etching product are in production field, often to run into and one of insoluble significant problem.Solving the Live leaking-stopping technology of special media leakage problem, is current urgent need very much and the larger new and high technology of difficulty.
In coal-gas recovering storing and transporting system, often run into gas pipe line corrosion failure, weld defect gas leakage, gas cabinet cabinet wallboard, piston plate gas leakage, specifically comprise that corrosion failure, weld seam slag inclusion, weld seam the problems such as reason such as tear.Once generation gas leakage, very easily causes that personnel are poisoning, even explosive accident of fire, when gas leakage point is larger, user is produced and causes impact in various degree, and be also a kind of great waste to the energy.When applying conventional seam leakage blinding technology and solving problems, first the emptying pipe of will stopping transport, purges displacement repeatedly with nitrogen or steam, reaches after testing after safety standard, guaranteeing under the condition of ventilating, can thoroughly solve leak stopping problem by the method for welding.In view of this, this leakage stopping technology, not only technique is loaded down with trivial details, the cycle is long, cost is high, easily accidents happened, and needs Subscriber Unit to stop work, stop production and repair, and causes very large economic loss and harmful effect to enterprise itself and society.
As shown in 5, gas pipe line 10 hydathode horn mouths 7 are in a very special position, once leak, leak source 6 is used conventional blocking method to be difficult to the effect that reaches satisfied, for example use adhesive tape to be wound around leak stopping method, because hydathode horn mouth 7 is tapers down, after adding gas leakage, horn mouth 7 outer walls can be stained with the wet and slippery water with tar, while causing being wound around with adhesive tape, be subject to force direction downward along taper, adhesive tape can slide to horn mouth 7 bottoms, exert oneself, adhesive tape, easily toward gliding, causes adhesive tape to be wrapped on leak source 6.Meanwhile, because horn mouth 7 tops are blocked by pipeline, position landform is very irregular, comprises that pasting board tension method, can repairing method are all inapplicable.
Summary of the invention
The purpose of this utility model is exactly to overcome the poor factor of above-mentioned exhaust duct horn mouth leak source plugging effect, and a kind of simple in structure, easy to operate, cheap safe and reliable gas pipeline drainer horn mouth leakage-baffling device of expense is provided.
For achieving the above object, the gas pipeline drainer horn mouth leakage-baffling device that the utility model is designed, comprise the can with the laminating of gas pipeline drainer horn mouth outside, its special way is: also comprise the dunnage with the laminating of draining horn mouth bottom dust flue, sealing leakage glue mud is housed in described can, described can and hydathode horn mouth faying surface are provided with opening, are provided with annular fastening steel band on described can, and described can lower end is connected by hinged bar with dunnage.
Further, described annular fastening steel, with two groups, is separately positioned on the upper and lower end of can.
Further, described can and dunnage are that antistatic, anti-metal bump spark material are made.
Of the present utility modelly be a little:
1, can under gas pipe line runnability, carry out the processing of privileged sites leak source, not affect production run.
2, for moving rear soldering of later stage provides reliable guarantee, greatly improved the Security of leak stopping.
3, the utility model outfit can be manufactured in batches according to the large ting model of hydathode, also can be only to special hydathode customization, have simple for productionly, and install simple.Feature simple in structure, easy and simple to handle, expense is cheap and safe and reliable, and be easy to apply.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Gas pipe line horn mouth leak source structural representation shown in Fig. 5 explains in background technique the inside, just repeats no more here.
Gas pipeline drainer horn mouth leakage-baffling device as shown in Fig. 1~4, comprise the can 1 with gas pipe line 10 hydathode horn mouth 7 outside laminatings, also comprise the dunnage 4 with 8 laminatings of draining horn mouth bottom dust flue, sealing leakage glue mud 2 is housed in can 1, described can 1 is provided with opening with hydathode horn mouth 7 faying surfaces, on described can 1, be provided with annular fastening steel band 3, described can 1 lower end is connected by hinged bar 5 with dunnage 4.The fastening steel band 3 of annular has two groups, is separately positioned on the upper and lower end of can 1.Can 1 and dunnage 4 are that antistatic, anti-metal bump spark material are made.
The utility model is applied in gas pipe line 10 hydathode horn mouth 7 conical surface leak sources 6; Leak stopping pipeline on-line operation pressure≤25kPa.Before practicality, be ready to instrument, spanner or special leak stoppage tool, also will prepare safety device, respirator, flame-retardant clothing, carbon monoxide detector.Concrete operation step is as follows: first according to horn mouth 7 conical surface length, determine can 1 length, according to horn mouth bottom, determine the length of dunnage 4 to the distance between first valve upper flange 9, each spot size is made special tool after determining.Before using, in can 1, fill sealing leakage glue mud 2, then can 1 is close to horn mouth 7 leak sources 6, dunnage 4 is close to horn mouth 7 bottom dust flues, the angle of utilizing moveable hinge pole 5 to regulate between can 1 and dunnage 4, make it to fit like a glove with horn mouth 7 taperings, then utilize annular fastening steel band 3 that special tool is fastening, until leakage rate obviously reduces or be zero.After leak source 6 is blocked, can 1 is directly welded on horn mouth, makes it to play permanent leak stopping effect, or at the large can of horn mouth 7 external welding, horn mouth 7 is wrapped up completely, reach the effect of complete leak stopping.The item of should taking care in operation:
1, operating personnel carries out two and wears one and wear, and requires to wear flashproof suit, forbids that operation unrelated person enters operation area.
2, guarantee that mask makes well flexibly, pressure is sufficient.
3,, during plugging operations, near pipe network and along the line is forbidden fire operation, in 40 meters without high temp objects.
