Abstract
The invention relates to a method for atmospheric leakage stopping, comprising the steps of: determining the size of a leakage hole, then preparing a fluid pipeline with a relative inner diameter; mounting a lockable valve in the fluid pipeline, welding one end of the fluid pipeline with periphery of the leakage hole when opening the valve; until completely sealing the end of the fluid pipeline with periphery of the leakage hole, closing the valve, then finishing leakage stopping. The technical scheme provided by the invention converts difficult pressure sealing into low pressure welding, evenactual welding, reduces difficulty and danger of welding, improves operability and operational efficiency of leakage stopping, and ensures equipment maintenance capacity of enterprises.
Description
Technical field
The present invention relates to a kind of method of handling pipe leakage, refer in particular to a kind of method that pressure sealing is converted to atmospheric leakage stopping.
Background technique
At present, in high temperature, high-tension apparatus and the working line thereof of industries such as oil, chemical industry, metallurgy, papermaking, pharmacy, inevitably the pipe leakage problem can appear, this not only can cause loss of material, energy waste, environmental pollution, and entail dangers to equipment and personal safety, even cause accident such as stop operation, bring very large economy loss to enterprise, therefore occur leaking with regard to needing and in time handle.Existing processing is leaked and had two kinds of methods: a kind of is to shut down to handle; The 2nd, do not shut down direct processing.Shutting down to handle has influenced operation, brings certain loss to production; Major part all adopts and does not shut down direct processing at present.But existing the shutdown handled leak stoppers because of being subjected to its structural limitations, needs many people, multi-pass operation just can finish.Mainly be not shut down direct processing all to need leak stopping under high-pressure situations, troublesome poeration, the activity duration is long, and labor intensity is big, and is dangerous.
Summary of the invention
In a single day the pipeline with pressure of operation, container are sewed at present, and the processing that be in operation all needs to be fixed to leak by welding or will handling part with instruments such as screws under the condition of high pressure, troublesome poeration, activity duration is long, and labor intensity is big, and is also very dangerous concerning the operator.
In order to address the above problem, the present invention by the following technical solutions.
A kind of method for atmospheric leakage stopping, this method implementation step is:
1) sews the affirmation of hole size, prepare the fluid line of the corresponding size of diameter according to the size of leak holes;
2) valve that installing can be sealed in described fluid line;
3) make valve be in opening state, with an end of fluid line and the welding on every side of leak holes, flow out from valve owing to reveal medium during welding, make weld, thereby the band pressure welding that difficulty is higher has been transformed into the lower normal pressure welding of difficulty not because of the leakage of medium produces pressure;
4) etc. an end of fluid line and leak holes around be soldered to sealing back throttle down fully.
The technological scheme provided by the present invention band pressure welding that difficulty is higher connects and is transformed into low-pressure welding dexterously, reduced the difficulty and the danger of welding, improved leak stopping operability and operating efficiency, guaranteed the plant maintenance ability of enterprise.
Description of drawings
Fig. 1 is the device schematic representation of method for atmospheric leakage stopping of the present invention.
Embodiment
For the ease of those skilled in the art's understanding, the present invention is further illustrated below in conjunction with embodiment and accompanying drawing, and the content that mode of execution is mentioned not is a limitation of the invention.
Be a kind of embodiment of the present invention as shown in Figure 1, a kind of method for atmospheric leakage stopping, this method implementation step is: 1) leak holes on the pipeline 12 is carried out the affirmation of size, prepare the fluid line 5 of corresponding internal diameter size according to the size of leak holes; 2) valve 3 that installing can be sealed in this fluid line 5; 3) make valve 3 be in opening state, with an end of fluid line 5 and the welding on every side of leak holes 2, flow out from valve owing to reveal medium during welding, make weld 4 not because of the leakage of medium produces pressure, thereby the band pressure welding that difficulty is higher has been transformed into the lower normal pressure welding of difficulty; 4) etc. an end of fluid line 5 and leak holes around be soldered to sealing back throttle down 3 fully; Promptly finish the leak stopping operation.Generally speaking, the internal diameter of described fluid pipeline gets final product for 5～50 millimeters greater than the leak holes aperture.
Claims (2)
1, a kind of method for atmospheric leakage stopping, this method implementation step is:
1) carries out the big or small affirmation of leak holes (2), prepare the fluid line (5) of corresponding pore size according to the size of leak holes;
2) valving (3) in described fluid line;
3) make valve (3) be in opening state, with an end of fluid line (5) and the welding on every side of leak holes (2);
4) throttle down (3) after fluid line (5) and being soldered on every side of leak holes seal fully.
2, method for atmospheric leakage stopping according to claim 1, the internal diameter that it is characterized in that described fluid pipeline is greater than 5～50 millimeters in leak holes aperture.
