The iron cone assembly provided by the embodiment of the utility model is used for repairing the oil hole through the following methods:

Insert and clamp the iron cone assembly into the oil stealing hole on the oil pipeline (the tapered end 2 is provided for easy insertion, and the cylindrical body 1 is stuck in the oil stealing hole), and then the iron cone assembly is welded to the oil stealing hole Integral (specifically, the connection between the cylindrical body 1 and the oil stealing hole is integrally welded). Since the cylindrical body 1 and the tapered end 2 are provided with through-holes 3 connected sequentially from top to bottom, during the welding process, the oil and gas in the oil pipeline are discharged from the through-holes 3, thereby avoiding overflow from the welding position, This can effectively reduce the pressure in the oil pipeline and reduce the risk of welding. After the welding is completed, the sealing member 4 is sealed and inserted into the through-hole 3 to seal the through-hole 3 to prevent oil and gas from overflowing therein, so as to realize the final sealing of the oil pipeline. In order to ensure the sealing reliability of the blocking member 4, the blocking member 4 and the through hole 3 may be welded as one.

In the iron cone assembly provided by the embodiment of the utility model, since the cylindrical body 1 and the conical end 2 are provided with a through hole 3 connected sequentially from top to bottom, the cone end 2 is inserted and stuck on the oil delivery pipe. When the oil stealing hole on the road is welded together with the iron cone assembly and the oil stealing hole, the oil and gas in the oil pipeline can overflow from the through hole 3, which reduces the pressure in the oil pipeline, reduces the risk of welding, and avoids fire. sex is better. And, after the welding is completed, by inserting and sealing the through hole 3 by using the plugging member 4, oil and gas are prevented from overflowing from the iron cone assembly, and the effective plugging of the oil stealing hole on the oil pipeline is realized. It can be seen from this that the The iron cone assembly has good sealing performance, high operational safety, and low manufacturing cost, which is beneficial and popularized.

In the embodiment of the utility model, the structure of the blocking member 4 can be various, and the structure of the blocking member 4 can be adjusted at any time according to the structure of the through hole 3, as long as the through hole 3 can be sealed, the following will The structure of the blocking member 4 is illustrated as follows:
