The circulating water is generally used for cooling the medium in the enterprise production, after the water is cooled by a fan and a cooling tower in a circulating water supply section, the water is sent to cooling equipment such as a coal gas primary cooler, a heat exchanger or an equipment lubricating oil cooler and the like which need to be cooled in the production process by a circulating water pump, after the medium is cooled by the circulating water through the cooling equipment, the water temperature is increased, the medium returns to the circulating water section, and then the circulating water is cooled, and the steps are repeated.
The circulating water is at the in-process of circulation, because the circulating water is in each cooler that passes through, the medium string leaks the phenomenon often appears, make partial medium like sulphuric acid, the wash oil, ammonia still get into the circulating water such as waste water, the degree of corrosion of circulating water to the pipeline has been increased, after this kind of condition appears, though through trading water, measure such as alkali is handled, but the day of a long time, the circulating water pipeline still often causes the local wall of pipeline to thin because of corroding to appear leaking the water spot, in addition pipeline outside part anti-rust paint drops, the degree of corrosion of pipeline has been aggravated, the circulating water pipeline leaks and has influenced the normal clear of production.
When a leakage point occurs in a circulating water pipeline, the treatment method generally comprises two cases: one is a temporary simple process. Namely, a clamp is beaten, a rubber mat is padded, or a leaking point is nailed by a peg of a wooden peg, and then a plugging agent is used for smearing and a yarn winding cloth is used for processing; the other method is a permanent treatment method, namely stopping the water pump to drain water in the pipeline and performing direct repair welding or patching repair welding on a leakage point. However, in actual production, if the pump is stopped and the water treatment is stopped, the production is greatly influenced, and the production is stopped. Therefore, the treatment of the leakage point of the circulating water pipeline under the condition of not stopping water is an urgent need of production, so that the great influence of water stopping treatment on the production can be avoided.
Disclosure of Invention

manufacturing a sleeve by using a steel plate, sleeving the sleeve on a water pipeline leakage point bound by asbestos cloth, and supporting the lower end of the sleeve on a gasket;
welding the sleeve, the water pipeline and the gasket together, and painting anti-rust paint on the sleeve and the gasket to finish the treatment of the water leakage point of the water pipeline.
And fourthly, the gasket welded on the water pipeline below the leakage point of the water pipeline is made of a steel plate and is annular, and the inner diameter of the gasket is matched with the outer diameter of the water pipeline.
In the fifth step, the inner diameter of the sleeve is matched with the outer diameter of the water pipeline, and the outer diameter of the sleeve is smaller than the outer diameter of the gasket.
In the step I, the rubber pad padded at the leakage point of the water pipeline is square, and the size of the rubber pad is larger than that of the leakage point of the water pipeline.
In the step I, a clamp for clamping the rubber mat is a circular ring surrounded by a rectangular thin iron plate, and the rubber mat clamped at the leakage point of the water pipeline is fastened through bolts.
The invention has the beneficial effects that: and the adverse effect on production caused by shutdown due to water shutdown treatment is avoided. Simple and practical, low treatment cost, good leakage stopping effect, safety and reliability.
