Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting repair, in particular to a pipe fitting repair device. Background Art

[0002] At present, most of the tailings conveying pipelines in my country's old mines are still made of cast iron pipes. Due to the long service time and severe local wear, it is often found that the tailings pressure cast iron pipelines will burst or break during normal production, resulting in unplanned shutdowns and repairs, reducing labor productivity; at the same time, the dispersion of tailings has a certain impact on the environment and also poses a certain risk to equipment repair and maintenance personnel; since cast iron pipes are not suitable for welding repairs, the usual practice is to use a temporary casing to connect the broken parts, fill the space between the casing and the cast iron pipeline with fillers, and seal the two ports with high-grade cement mortar and a certain amount of accelerator; its disadvantage is that it is affected by many factors such as cement grade, aggregate, additives, setting time, and pouring, and the effect is often not ideal. Cement loosening and leakage will occur after long-term use; at the same time, the cement setting time is relatively long, which affects the resumption time and production operation rate.

[0011] A steel ring is slidably sleeved on the outer wall of the first cast iron pipe or the second cast iron pipe, and the diameter of the steel ring is larger than the gap between the inner wall of the steel pipe and the outer wall of the first cast iron pipe or the outer wall of the second cast iron pipe;

[0012] Soft filler, located between the spacer ring and the steel ring;

[0013] The connection assembly is used to squeeze the steel ring toward the pipe mouth of the steel pipe so that the soft filler can block the gap between the steel pipe and the first cast iron pipe and the second cast iron pipe.

[0014] Preferably: the connection assembly includes

[0015] A flange is fixedly sleeved on the outer side wall of the first cast iron pipe or the second cast iron pipe;

[0016] A plurality of nuts are respectively fixedly connected to the outer side wall of the steel pipe, and the flange has positioning holes at positions corresponding to the nuts;

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 In the first embodiment, a pipe repair device includes:

[0028] A first cast iron pipe 10 and a second cast iron pipe 20;

[0029] The steel pipe 30 has two ends which are respectively slidably sleeved on the outer wall of the broken end of the first cast iron pipe 10 and the outer wall of the broken end of the second cast iron pipe 20;

[0030] Two sealing components are respectively arranged between the inner wall of the steel pipe 30 and the outer wall of the first cast iron pipe 10 and the outer wall of the second cast iron pipe 20;

[0031] Two connecting assemblies 60 are respectively arranged on the first cast iron pipe 10 and the second cast iron pipe 20, and are used to connect the steel pipe 30;

[0032] The sealing assembly includes

[0033] The spacer ring 31 is seamlessly welded to the inner wall of the steel pipe 30 and is slidably sleeved on the outer wall of the first cast iron pipe 10 or the second cast iron pipe 20;

[0034] A steel ring 40 is slidably mounted on the outer wall of the first cast iron pipe 10 or the second cast iron pipe 20, and the diameter of the steel ring 40 is larger than the gap between the inner wall of the steel pipe 40 and the outer wall of the first cast iron pipe 10 or the outer wall of the second cast iron pipe 20;
