[0020] like Figures 1 to 8As shown, a pipeline sealing kit includes a cylindrical main body mating connection column 1 made of metal material, the upper end of the main body mating connection column 1 is provided with an integrally formed conical assembly stop connection column 2, the size of the lower end surface of the assembly stop connection column 2 is larger than the diameter of the main body mating connection column 1, and the main structure at the lower end position can be directly inserted into the mating hole of the joint assembly during assembly. The upper end center position of the assembly stop connection column 2 is provided with an inverted conical main body assembly combination groove 3, which can be inserted and matched with the oil pipeline at the upper end. The lower end center position of the main body assembly combination groove 3 is provided with a mating installation hole that penetrates the entire lower end surface, and the mating installation hole is provided with an integrally formed cylindrical assembly stop mating boss 4 near the upper end, the lower end of the assembly stop mating boss 4 is a horizontal surface, and the upper end of the assembly stop mating boss 4 is a conical structural surface, which ensures that the combination operation during mating is more convenient and the mating fluency is better. A first sealing matching groove 5 with a V-shaped cross section is provided at the position where the upper end of the assembly stop matching boss 4 is connected to the main body assembly combination groove 3, and the matching sealing ring can ensure the matching sealing at the upper end position. The lower end of the assembly stop matching boss 4 is provided with a cylindrical second sealing matching groove 6 that completely penetrates the lower end surface of the main body matching connection column 1, and the cylindrical surface of the second sealing matching groove 6 is provided with a sealing reinforcement stabilizing column 7 distributed up and down and with a V-shaped cross section, which on the one hand improves the strength of the structure, and on the other hand can cooperate with the sealing ring for better sealing, thereby achieving a double sealing effect. The V-shaped structure of the sealing reinforcement stabilizing column 7 and the first sealing matching groove 5 are in opposite directions, and the size of the center position of the lower end of the main body assembly combination groove 3 is larger than the size of the center position of the lower end of the assembly stop matching boss 4.
