Abstract
The invention discloses a method for stopping leakage of a valve or a pipe irregularly deformed due to rusting. The method includes the steps that a leakage point is pretreated; a rust layer is brushed through a Black Knight product twice; a brushed region is coated with a plastic film; two parts of a Bexane adhesive are mixed, the deformed valve or the deformed pipe are coated with the Bexane adhesive, and it is guaranteed that the leakage point is exposed outside without being plugged; after 24 hours of air drying, a quick cure is kneaded and activated and is tightly attached to the surface of the leakage point, and the leakage point can be plugged; after the surface of the quick cure is coated with a plastic film, the portion coated with the quick cure is rapidly sleeved with a clamp so as to be fastened; after the quick cure is completely cured, the portion is coated with a layer of the Bexane adhesive again, and the whole clamp is completely coated; soap liquid is used for testing the leakage point; and Mega stretch and seal is wound around the surface of the leakage point till the clamp is completely coated, and an insulation material is used for covering the surface of the repaired leakage point. By the adoption of the method, leakage stoppage operation can be directly implemented on a high-pressure gate station pipeline without a gas halt, and leakage stoppage of the valve or the pipe can be achieved within a short time; and no potential safety hazard exists in the construction process and no large threat is caused to a natural gas gate station.
Description
Technical field
The present invention relates to pipeline construction technological method, particularly relate to and a kind ofly cause the valve of irregular deformation or the blocking method of pipe fitting due to corrosion.
Background technique
Quickening along with popularization construction speed has driven the expansion of the supporting pipeline network construction work of rock gas, and installation and the retrofit work of Urban Underground gas distributing system are also more and more frequent.Consider the feature of urban population dense, all kinds of enterprises and institutions distribution Relatively centralized, make gas distributing system retrofit work of getting angry in city there is certain risk.Therefore, the retrofit work in order to ensure city gas distributing system carries out smoothly, avoids affecting industrial production gas and Domestic Gas, and on-line production rebuilding construction technology is used more widely in increasing occasion.
The natural gas line in general city is longer, several kilometers at least, dozens of kilometres at most, and caliber is comparatively large, at present for the valve or pipe fitting that cause the valve of irregular deformation or pipe fitting leak stopping mainly to stop the supple of gas or steam more to renew due to corrosion.If adopting gets angry change construction, first by rock gas in inert gas replacement pipe, not only length consuming time must be done like this, and waste.Cannot realize for the high-pressure door station that can not stop the supple of gas or steam, gas leakage can only be let alone, there is larger risk; Irregular valve or the pipe fitting blocking construction cycle longer, need to coordinate and to prepare material many, inside door station, construction risk is higher.
Therefore, it is a kind of when on-line production that those skilled in the art is devoted to exploitation, because corrosion causes the valve of irregular deformation or the construction technique of pipe fitting leak stopping, ensures construction effect and be reduced to minimum by construction on the impact of user.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is how at on-line production, carries out leak stopping operation when not getting angry to the valve or pipe fitting that cause irregular deformation due to corrosion.
For achieving the above object, the invention provides and a kind ofly cause the valve of irregular deformation or the blocking method of pipe fitting due to corrosion, comprise the following steps:
S1, use brush class instrument carry out pretreatment to leak source, make the Surface Rust of leak source exposed, smooth;
S2, use rust-proofing become brushing rusty scale twice;
S3, the use coated printed regions of plastic pellicle, lost efficacy to avoid meeting water;
S4, tear plastic pellicle off, two component blending can be connect hundred, be coated on deformation valves or pipe fitting, and guarantee that leak source is exposed, not do shutoff;
S5, after air-dry 24 hours, kneading activate admittedly can connect, adhere well to leak source surface, implement leak stopping;
S6, after admittedly can connecing Surface coating plastic pellicle, apply mechanically clamp rapidly;
S7, after admittedly can connecing solidification completely, then be coated with one deck hundred and can connect, whole fixture is filled completely;
S8, use foam liquid leak test;
S9, use MAG close winding leak source are surperficial completely coated to fixture;
S10, use insulating material cover the surface after leak source repairing.
Further, described brush class instrument is hairbrush or copper brush or steel brush.
Further, in step S2, after brushing air-dry 20 minutes for the first time, carry out second time brushing again; Second time brushing after air-dry 24 hours.
Further, in step S10, described insulating material is insulation rubber cushion or insulating paint.
Further, also comprise: S11, dismounting fixture.
Further, described fixture adopts stainless steel to customize according to the profile of deformation valves or pipe fitting.
Further, described foam liquid is the water-soluble dilution of soap or the water-soluble dilution of detergent or the water-soluble dilution of high foam detergent powder or the water-soluble dilution of high foam laundry liquid.
Further, the thickness of described plastic pellicle is between 0.05mm ~ 0.15mm.
Further, described rust-proofing becomes model to be BK-104.
Further, described hundred ratios that can connect two component blending are 1:1.
One of the present invention, at on-line production, when not getting angry, because corrosion causes the construction technique of the valve of irregular deformation or the leak stopping of pipe fitting, has following technique effect:
1, the present invention directly can implement plugging operations by chemical product at the valve of not stopping the supple of gas or steam on the pipeline of high-pressure door station or pipe fitting;
2, the present invention can realize irregular deformation valve or pipe fitting plugging operation within a short period of time;
3, material used herein is more single, and personnel depaly compares simplifies;
4, there is not potential risk in the present invention in work progress, can not cause larger threat to natural valve station.
Embodiment
Below embodiment of the present invention is further elaborated:
1. get out material required for operation, include brush, rust-proofing becomes, plastic pellicle (thickness is 0.12mm), and hundred can connect, admittedly can connect, soap solution, MAG is close, insulation rubber cushion, paint etc.;
2. find leak source, utilize the instrument such as hairbrush or copper brush to carry out pretreatment, make leak source Surface Rust exposed, smooth;
3. use rust-proofing to become BK-104 brushing rusty scale twice, brush air-dry rear (about 20min) first and carry out secondary operation again, brush complete, wait to do.With the coated printed regions of plastic pellicle, avoid meeting water and lost efficacy;
4. brush after complete 24 hours, tear plastic pellicle off, product blending of can practicing midwifery hundred is even, gets lodged on valve because corrosion causes irregular deformation or pipe fitting, guarantees that leak source leaks and do not do shutoff outside;
