Abstract
The utility model relates to a take gas to repair gas piping device, a serial communication port, the device is including prefabricated steel sheet, be provided with the screw hole in the middle of the prefabricated steel sheet, connect the drainage tube on the screw hole, be provided with the ball valve on the drainage tube, be provided with one deck fireproofing mud around the prefabricated steel sheet. When pressure gas piping leaks, through prefabricated steel sheet and fireproofing mud's effect, make the device tightly adsorb on the gas leakage pipeline to the burning is drawn with coal gas to drainage tube by in the middle of the device, and the electric welder of being convenient for need not to wear the air respirator just can carry out the mending -leakage to the pipeline, directly closes the ball valve on the drainage tube after the welding, guarantees equipment security in process of production.
Description
Technical field
This utility model relates to a kind of band gas and repairs gas piping device, belongs to pressure gas piping technical field.
Background technology
Gas piping has blast furnace gas pipeline, coke oven gas pipe, converter gas pipeline, it is low that pressure has height to have, caliber varies, but leak regardless of any, serious consequence is caused in capital, particularly when caliber is more than 100 millimeters, it is impossible to directly close valve cut-out source of the gas and carry out putting out a fire or overhauling, in case back draft.The method of general mending-leakage is mended by replacing a damaged part, direct soldering, subsidize.Mend by replacing a damaged part and namely defective position is cut away, change new steel, adopt the method for butt welding to repair.Namely direct welding need not dig up rejected region, and directly in fault location welding, repairs defect with the welding material of fusing.And subsidizing is directly at defect external application one block plate, then steel plate surrounding is welded mutually with wallboard.The invention of this patent, it is contemplated to when leakage occurs, by effective means, coal gas is drawn burning, repairing area is made not produce to build the pressure, quality will be caused affect the weld seam repaired, it is to avoid the generation of second accident and secondary injury, simultaneously repairing personnel do not need to wear air respiratorresuscitator can direct operation, extend the activity duration and improve operating condition, it is ensured that the safety of field operation.
Chinese patent application CN91101414.4 discloses " rapid leakage-blocking method for pressure bearing installation and equipment ", its flow process is: adopt the leak stopping magnet piece of high magnetic and sealing leakage glue to combine, adopt and include master lever, there are the orientation positions plate of a baffle plate being converted into certain angle and the pressure sealing equipment of movable pulley in secondary stick, magnetism positioning device, supporting positioning device, front end, leakage facility, container or pipeline are carried out pressure sealing when not stopping work, good operation safety, can be rapidly completed plugging operation.
The mode that the leak stopping magnet piece of the above frame mode high magnetic of employing and sealing leakage glue combine, blocks pressure pipeline.But the accuracy of closure is had certain requirement by this structure, if blocking unsuccessful, it is necessary to again block, cumbersome；And installations and facilities are complicated, operating procedure is complicated.Therefore, a kind of new technical scheme of exigence solves above-mentioned technical problem.
Summary of the invention
In order to solve above-mentioned Problems existing, the utility model discloses a kind of band gas and repair gas piping device, this technical scheme simple in construction, compact, design ingenious, it is possible to the coal gas that will leak out in time draws burning, it is simple to the maintenance of pipeline.
To achieve these goals, the technical solution of the utility model is as follows, a kind of band band gas repairs gas piping device, it is characterized in that, described device includes prefabricated steel, is provided with screwed hole in the middle of described prefabricated steel, and described screwed hole connects drainage tube, being provided with ball valve on described drainage tube, the length of described drainage tube is 20-40cm.
A kind of improve as of the present utility model, described prefabricated steel be provided around one layer of fire-proof mud.
As a kind of improvement of the present utility model, the area of described prefabricated steel is more than the area of leakage hole.
As a kind of improvement of the present utility model, the other end of described drainage tube is provided with port.
Relative to prior art, advantage of the present utility model is as follows, 1) whole Technical Design is ingenious, simple and compact for structure, and this device is applicable to not stop the pipeline of labour maintenance；2) in the process of repair welding, operating personnel can not wear air respiratorresuscitator and carry out operation, and operation comfort level and precision increase；In the process of repair welding, will not produce to build the pressure, not affect the quality of weld seam；By the burning to emission coal gas, it is possible to the effective minimizing toxic and harmful harm to environment；3) this technical scheme is less costly, it is simple to large-scale popularization and application.

Detailed description of the invention
In order to deepen to be appreciated and understood by of the present utility model, below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model.
Embodiment 1:
Referring to Fig. 1, Fig. 2, a kind of band band gas repairs gas piping device, described device includes prefabricated steel 3, screwed hole 4 it is provided with in the middle of described prefabricated steel, on described screwed hole connect drainage tube 8, described drainage tube 8 is provided with ball valve 6, described prefabricated steel be provided around one layer of fire-proof mud, the area of described prefabricated steel is more than the area of leakage hole, and the other end of described drainage tube is provided with port 7.
Work process:Referring to Fig. 1, Fig. 2, this technical scheme operating process is divided into three steps:
1, prefabricated steel, in the tube circumference region of gas leak, it is contemplated that steel plate corrosion seriously not easily welds, and to place fire-proof mud in prefabricated steel, so should prefabricated steel be made to bigger 4-6cm than air-leak section；Opening a screwed hole in the centre of prefabricated steel, connect one for gas-fired drainage tube on hole, install small ball on the other hand in the middle of drainage tube in advance, drainage tube threaded one end can be connected with the screwed hole of prefabricated steel, and other end is used for the coal gas that burns.
2, install fire-proof mud additional in the surrounding of prefabricated steel, owing to prefabricated steel is directly having gap, impact welding with by the pipeline of repair welding, be then coated with last layer fire-proof mud in prefabricated steel surrounding, note the conduction hole not blocking centre.
3, the installation of prefabricated steel, the prefabricated steel central aperture made gas leakage point is installed, if gas leakage point is bigger, a stopper is first stamped at air-leak section, putting prefabricated steel again, use fire-proof mud to guarantee between prefabricated steel and repaired pipeline air tight, gas is derived by drainage tube, light institute's drain coal gas at drainage tube tip naked light again, make coal gas not discharge to surrounding and work the mischief.Now operating personnel can not wear air respiratorresuscitator prefabricated steel and pipeline are carried out formal welding.
After prefabricated steel surrounding repair welding completes, close the ball valve on drainage tube.When pipeline stops and using as a servant, take off drainage tube again replace with a sizeable bolt.
It should be noted that above-described embodiment is only preferred embodiment of the present utility model, it is not used for limiting protection domain of the present utility model, the equivalent replacement made on the basis of technique scheme or replacement, belongs to protection domain of the present utility model.
