Abstract
The utility model provides a partial pressurized leakage repairing plate of a coal gas pipeline. The partial pressurized leakage repairing plate is composed of a main plate, a gas-collecting and water-collecting device, a pressure relief drain valve and a plate-fastening clamp. After a hole is drilled in the middle of the main plate, the gas-collecting and water-collecting device is welded, and moreover the pressure relief drain valve is installed. The plate-fastening clamp fastens the main plate on the partial leakage position of the coal gas pipeline. The partial pressurized leakage repairing plate of the coal gas pipeline has the advantages of being simple in structure, convenient to manufacture, good in using effect and the like. By the utilization of the partial pressurized leakage repairing plate, a running coal gas pipeline or a running fuel gas pipeline can be repaired in an online mode even if gas is not stopped, hot work is not carried out, production is not stopped, the pipeline needs not to be cleaned and water also accumulates in the pipeline. Energy is saved, pollution is reduced, and besides, hidden danger of the hot work and explosion can be eliminated. Service life of the repaired pipeline can be more than ten years, and economical benefits are very prominent.
Description
Technical field
The utility model belongs to gaspipe network maintenance technique field, is specifically related to
The gas pipe line local etching is revealed band and is pressed the mending-leakage plate.
Background technique
The various gaspipe networks that use in large enterprises such as metallurgy, coking, reasons such as coal gas water of condensation are arranged owing to pipe interior during operation, inner or the outside local etching of gas pipe line often occurs, produce gas leakage, and leak site all occurs in below or the side-lower of pipeline.Coal gas is poisonous to be again flammable explosive gas, must in time repair in case take place to reveal, otherwise consequence is with hardly imaginable.Conventional restorative procedure be stop the supple of gas or steam, purge, welding etc.Stop the supple of gas or steam, just meaning stops production, and can not stop the supple of gas or steam substantially as the coke-stove gas main pipe, stops the supple of gas or steam and will cause heavy economic losses and serious environmental to pollute to production; Purge, need to consume a large amount of steam or nitrogen, pipeline is more big, the steam of more long consumption or nitrogen are just more many; Moreover there are not steam or source nitrogen again near a lot of gaspipe networks; Welding is got angry at gas pipe line exactly, and it is more dangerous particularly to get angry on the gas pipe line in trench, restricted clearance, the inflammable and explosive district such as indoor, generally forbids getting angry at gas pipe line in this type of area.Eventually the above, existing restorative procedure is science, rationally not to the utmost all, implements all to have certain drawback, causes in various degree economic loss to enterprise.
Summary of the invention
In order to solve the deficiency that above-mentioned prior art exists, the utility model provides a kind of making simple, easy for installation, and the respond well gas pipe line partial-band of mending-leakage is pressed the mending-leakage plate.Under the prerequisite that it can be implemented in and not stop production, not stop the supple of gas or steam, not get angry, the online gas pipe line of repairing all size in high quality.
For this reason, the technical solution of the utility model is:
A kind of gas pipe line partial-band is pressed the mending-leakage plate, is to be made of parts such as mainboard, gas collection water-collecting machine, pressure release drain valve and tight integrated circuit boards; Behind the borehole of mainboard middle part, be welded with the gas collection water-collecting machine, and the pressure release drain valve is installed, by tight integrated circuit board mainboard is fastened on the local leak site of gas pipe line, with elasticity and rigid seal material leak source is shut.
Described mainboard is to adopt steel plate to be made into the rectangular plate that has radian that is complementary with the gas pipe line external diameter, and the oily quadrel cotton cord that oozes is installed all around.
Described gas collection water-collecting machine is the steel can shape, upper opening and mainboard seal welding, and lower seal welding seamless steel pipe is connected with the pressure release drain valve.
Described tight integrated circuit board adopts the band steel band to make two ends weld bolt connecting plate.
The utlity model has rational in infrastructure, easy to make, advantage such as using effect is good.Use it, can not stop the supple of gas or steam, do not get angry, do not stop production, not need to clean pipeline, also be not afraid of to have in the pipeline under the situation of catchmenting the gaspipe network that moves is carried out online reparation.Be energy saving, reduce and pollute, can get rid of the hidden danger of getting angry, exploding again.Gaspipe network after repairing can reach more than 10 years working life, and annual minimizing stops production and loses more than 3,000 ten thousand yuan, reduces more than 200 ten thousand yuan of gas pipe line maintenance expensess, the economic benefit highly significant.This kind gas pipe line partial-band presses the mending-leakage plate to be applicable to diameter 50～3000 ㎜, and the local etching area is less than radially 1/3, various coal gas and the gas pipeline of pressure 0～1MPa, and application area is very extensive.
Description of drawings
Fig. 1 is that the gas pipe line partial-band is pressed mending-leakage plate cross-sectional configuration assembling schematic representation.
Among the figure: bolt 1, tight integrated circuit board 2, corrosion pipeline 3, rigid seal 4, elastic packing 5, mainboard 6, leakage point 7, gas collection water-collecting machine 8, pressure release drain valve 9.
Embodiment
Below in conjunction with embodiment the utility model is described in detail:
Be that 1220mm blast furnace gas corrosion pipeline 3 is example to repair external diameter, at cause the pipeline below leakage point 7 that diameter is 50mm to occur owing to corrosion, and the situation that has a large amount of coal G﹠Ws constantly to leak, make a kind of gas pipe line partial-band and press the mending-leakage plate, as shown in Figure 1.Be to be constituted by mainboard 6, gas collection water-collecting machine 8, pressure release drain valve 9 and tight integrated circuit board 2; Mainboard 6 is to adopt the 10mm Plate Steel to be made into the 500mm * 600mm rectangular plate that has 1220mm radian diameter, is complementary with corrosion pipeline 3 external diameters, and digs out welding gas collection water-collecting machine 8 behind the hole of diameter 140mm at mainboard 6 middle parts; Gas collection water-collecting machine 8 is the steel can shape of internal diameter 150mm, high 150mm, upper opening and mainboard 6 seal weldings, and lower seal welding internal diameter 25mm seamless steel pipe is connected with pressure release drain valve 9; Tight integrated circuit board 2 is 2 covers, is to adopt 3mm * 20mm band steel to do, and length is 3820mm, two ends weld bolt connecting plate, construction bolt 1.
Installation steps: with stopper leakage point 7 is blocked up earlier and annotate, to reduce the leakage rate of coal gas and water.Open pressure release drain valve 9 again, a spot of coal gas and water are diffused away, to reduce the pressure in the gas collection water-collecting machine, guarantee that mainboard 6 is anhydrous all around.Gas collection water-collecting machine 8 is aimed at leakage point 7 backs with tight integrated circuit board 2 mainboard 6 is installed on the corrosion pipeline 3, slowly alternately tighten 2 bolts 1, make mainboard 6 fixing, elastic packing 5 is stressed even.After again the outer wall that reaches pipeline 3 around the mainboard 6 being carried out the degreasing and rust removal processing, carry out sealing with pipeline outer wall around the mainboard with the metal sealer, the metal sealing glue solidifying is rigid seal 4 after 24 hours, closes pressure release drain valve 9.
