When the gas pipeline leaks, the utility model can repair the gas pipeline under pressure when the gas pipeline has normal pressure, and the gas pipeline does not need to stop production and stop work when the gas pipeline leaks, thereby ensuring the normal production of enterprises.
Description
Technical Field
The utility model relates to the technical field of metallurgy, in particular to an emergency repair device for a gas pipeline of a steel plant when leakage occurs.
Background
In a steel plant, because a large number of coal gas conveying pipelines with different diameters are laid according to production requirements, the pipelines are affected by expansion with heat and contraction with cold or corrosive substances in coal gas in a long-time use process, leakage cracks are generated on the pipelines, the coal gas leaks, normal production is affected, and safety accidents can be caused when the normal production is seriously affected. In addition, due to the production property of steel mills, normal production is continuous, and emergency stop cannot be performed, otherwise, large economic loss is caused, so that when the gas pipeline leaks, a gas pipeline pressure repairing device which does not stop working and production is needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a gas pipeline under-pressure repairing device which is used for repairing a gas pipeline under pressure without stopping production and maintenance when the gas pipeline leaks and can be used for repairing the gas pipeline under pressure when the gas pipeline has normal pressure.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a steel mill gas pipeline under-pressure repairing device is provided with a fixing frame, a compression bolt, a compression steel plate, a rubber plate and a magnet; the fixing frame is provided with a screw hole for fixing a compression bolt; magnets are arranged on the left side and the right side of the fixing frame; the magnet is bonded with the fixing frame.
The steel plant gas pipeline under-pressure repair device is characterized in that: the magnet is a neodymium iron boron magnet; the lower surface of the magnet is a concave surface corresponding to the gas pipeline.
In the steel mill gas pipeline under-pressure repairing device, four hold-down bolts are arranged; the positions of the compression bolts respectively correspond to the four corners of the compression steel plate; the lower end face of the pressing bolt is designed into a spherical surface.
According to the steel mill gas pipeline under-pressure repairing device, the pressing steel plate is designed to be arc-shaped corresponding to the gas pipeline.
According to the under-pressure repairing device for the gas pipeline of the steel plant, the outer dimensions of the pressing steel plate and the rubber plate exceed the outer dimensions of the leakage point by not less than 30 cm.
Advantageous effects
The utility model has the following advantages:
according to the steel mill gas pipeline under-pressure repairing device, when a gas pipeline leaks, a rubber plate and a compression steel plate are laid above a leakage point, a fixing frame is adsorbed on the outer skin of the gas pipeline through a magnet, a compression bolt is rotated to compress the gas pipeline, and the compression steel plate is welded in a sealing manner after the gas pipeline is detected to be qualified by a gas detector; the utility model can repair the gas pipeline under pressure when the gas pipeline has normal pressure, and does not need to stop production and stop work when leakage occurs, thereby ensuring the normal production of enterprises.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a left side view of the present invention;
in the drawings, the reference numerals denote: 1. the gas pipeline comprises a gas pipeline body 2, a fixing frame 3, a compression bolt 4, a compression steel plate 5, a rubber plate 6, a magnet 7, a leakage crack 8 and a welding line.
Detailed Description
The utility model is further illustrated by the following figures and examples.
The utility model relates to a pressurized repairing device for a gas pipeline of a steel plant, which is provided with a fixing frame 2, a compression bolt 3, a compression steel plate 4, a rubber plate 5 and a magnet 6; the magnets are neodymium iron boron magnets and are bonded in the middle parts of the left side and the right side of the fixing frame; the surface of the compression steel plate is concave and tile-shaped, and the concave surface corresponds to the surface of the gas pipeline; the lower end face of the compression bolt is matched with the compression steel plate and is designed into a spherical shape.
In the steel mill gas pipeline under-pressure repair device, the leakage crack 7 shown in figure 1 generally appears at the welding seam of the gas pipeline 1; when a leakage crack is generated due to the crack of a welding seam, the rubber plate 5 and the compression steel plate 4 are covered on the surface, the fixing frame 2 is adsorbed on the outer surface of the gas pipeline 1 through a strong magnet, the compression bolt 3 is rotated to compress, and finally the periphery of the compression steel plate 4 is hermetically welded with the gas pipeline after the detection of the gas detector is qualified, as shown in figures 1 and 2, 8 in the figures is the welding seam.
The pressurized repair device for the gas pipeline of the steel plant can be prefabricated into a plurality of groups in advance, and can be immediately organized and implemented when gas leakage occurs.
