Embodiment Construction

[0021] combine Figure 1-Figure 5 The technical scheme of the present invention is described:

[0022] (1) To make a rectangular lead block box, make use of the low melting point and good ductility of the lead block to make a rectangular lead block box, and melt the lead block into the rectangular lead block box to make a rectangular lead plate.

[0023] (2) According to the shape of the leak point of the gas pipeline, cut the rectangular lead plate obtained in step (1) into a small cuboid slightly larger than the shape of the leak point with a bow saw, and then smash it into the required shape with a hammer. Smashing into a round rod shape has less resistance and is easier to enter. Then use a copper chisel to chisel the round lead rod at the front to the required size, and align the round lead rod with the leak point of the gas pipe and smash it with a copper hammer. enter.

[0024] (3) Make a rectangular steel box, and fill the box with yellow mud. Then drill a hole at o...

Abstract

The invention discloses a device and a method for stopping leakage of a gas pipeline. Firstly, a lead piece is used for stopping leakage of a leaking part; for further preventing gas leakage, a steel box full of yellow mud is used for welding leaking positions, so that leaking points of the gas pipeline can be completely prevented from leakage. The leakage stoppage method is simple in steps, safe, reliable, high in applicability and applicable to leakage stoppage of gas systems and air pipes.

Description

technical field [0001] The invention relates to a pipeline leakage plugging device and method, in particular to a gas pipeline leakage plugging device and method. Background technique [0002] In a gas power plant, because the gas contains acidic media, it is easy to cause gas pipeline leakage. In practical applications, when plugging gas pipeline leakage, various plugging methods are generally used according to working conditions, processing capabilities, and site conditions ( There are mechanical plugging method, plug hole plugging method, welding repair plugging method, adhesive plugging method, glue plugging sealing method, replacement sealing method, etc.) combined for plugging, such as: plugging wedges first, then bonding, Finally, it is mechanically fixed (welding the fixing frame first, then using sealant, and finally mechanically pressing) and other methods. However, each plugging method has its own limitations and applicable conditions. If the method is not adopte...
