Abstract
A leakage stopping method comprises the steps of firstly confirming the size of a leakage hole of a conveying pipeline, preparing a fluid pipeline with the corresponding hole diameter according to the size of the leakage hole, arranging a sealing device in the fluid pipeline, welding one end of the fluid pipeline with the periphery of the leakage hole in an opening state of the sealing device, and closing the sealing device after one end of the fluid pipeline and the periphery of the leakage hole are welded to be completely sealed; and then the plugging operation is completed. The technical scheme provided by the invention skillfully converts the difficult pressure welding into low pressure welding or even conventional welding, reduces the difficulty and danger of welding, improves the operability and operation efficiency of leakage stoppage, and ensures the equipment maintenance capability 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 blocking method, this method implementation step is:
1) leak holes of conveyance conduit is carried out big or small affirmation, prepare the fluid line of corresponding pore size according to the size of leak holes;
2) in described fluid line, install sealing device;
3) sealing device is under the 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) close sealing device when being soldered to fully around fluid line and the leak holes after the sealing, the leak stopping operation is finished.
Described sealing device is valve or the flange plate that has closure plate.
The internal diameter of described conveyance conduit is greater than 5～50 millimeters in leak holes aperture.
The technological scheme provided by the present invention band pressure welding that difficulty is higher connects and is transformed into low-pressure welding dexterously, has reduced the difficulty and the danger of welding, has improved the operability and the operating efficiency of leak stopping, has guaranteed the plant maintenance ability of enterprise.
Description of drawings
Fig. 1 adopts the device schematic representation of valve sealing for blocking method sealing device of the present invention;
Fig. 2 adopts the device schematic representation of flange dribbling closure plate sealing for blocking method sealing device of the present invention.
Embodiment
The present invention is exactly that the band pressure welding that difficulty is higher connects and is transformed into low-pressure welding dexterously, has reduced the difficulty and the danger of welding, has improved the operability and the operating efficiency of leak stopping.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.
Embodiment 1.
Be a kind of embodiment of the present invention as shown in Figure 1, a kind of blocking method, sealing device adopts valve, and this method implementation step is: 1) leak holes on the conveyance conduit 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 conveyance conduit gets final product for 5～50 millimeters greater than the leak holes aperture.
Be a kind of embodiment of the present invention as shown in Figure 2, a kind of blocking method, sealing device adopts the flange plate of band closure plate, this method implementation step is: size, the shape of 1) carrying out Leak hole 2 on the conveyance conduit 1 are confirmed, prepare the timber wedge 7 of corresponding size, shape according to size, the shape of Leak hole 2; 2), prepare the fluid line 5 of corresponding pore size according to the size of Leak hole 2; 3) on described fluid line 5, load onto flange plate 3; 4) according to described flange plate 3 sizes, the closure plate 6 that preparation is corresponding supporting; 5) throw described timber wedge 7 into Leak hole 2 sealings, the type ejection if current are in line, and leak when little, can not play timber wedge; 6) end and the Leak hole 2 with described fluid line 5 welds on every side; 7) after described fluid line 5 and Leak hole 2 weld well on every side fully, closure plate 6 is connected with flange plate 3 with screw; 8) convection cell pipeline 5, flange plate 3, closure plate 6 carry out preservative treatment, and the leak stopping operation is finished.Generally speaking, the internal diameter of described conveyance conduit is greater than 5～50 millimeters in leak holes aperture, and the pressure of described conveyance conduit leak is less than 0.5Mpa.
More than for the preferable implementation of the present invention, need to prove, conceive under the prerequisite any conspicuous replacement all within protection domain of the present invention not breaking away from the present invention.
