the oil pipe sealing device further comprises a retractable tight sleeving tool made of metal, and the tight sleeving tool is sleeved on the circular flange of the oil pipe; the sleeving tool is adsorbed on the lower surface of the permanent magnetic chuck, and tightly presses the circular flange of the oil pipe on the lower surface of the permanent magnetic chuck; and the air passage on the lower surface of the permanent magnetic chuck is relatively communicated with the oil pipe.
It further comprises the following steps: the tight frock of cover includes relative semicircular ring shape's left semi-ring, right semi-ring, and the one end of left semi-ring, right semi-ring is articulated through the round pin.
The inner walls of the left half ring and the right half ring are in a ladder shape, and the inner walls of the left half ring and the right half ring are buckled on a circular flange of the oil pipe.
And a sealing ring is arranged on the end face of the circular flange.
Compared with the prior art, the beneficial effects of the utility model are that:
the permanent magnetic chuck structure is adopted for clamping, and a tightening tool is matched, so that the suction force is increased, the flange sealing surface is rapidly sucked, and the flange end is ensured to be firm; the suction force is controlled to be generated and closed through the permanent magnetic chuck switch handle, the structure is simple, the operation is convenient, the disassembly is convenient, and the universality and the reliability are high; the permanent magnetic chuck has strong suction force, small volume, stable magnetic force and no loss, is suitable for pressure test of various flange oil pipes, has high pressure test efficiency, and improves the reliability of oil pipe products.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in figures 1 to 5, the pressure test tool for the circular flange structure quick sealing oil pipe is characterized in that the lower surface of a permanent magnetic chuck 1 is a plane, an air inlet pipe 2 is fixed on the side surface of the permanent magnetic chuck 1, and an air passage communicated to the air inlet pipe 2 is formed in the center of the lower surface of the permanent magnetic chuck 1. The permanent magnetic chuck 1 is provided with a switch wrench 3 for controlling the magnetism of the permanent magnetic chuck 1.
The tight frock of cover is made by the metal material, and the tight frock of cover includes relative semicircular ring shape's left semi-ring 6, right semi-ring 4.
