[0023] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail in combination with the drawings.

[0024] As Figures 1-4 ​As shown in the figure, a pipeline connection protection device comprises a flange male disc 1 and a flange female disc 2, and the two are inserted and locked through a threaded rod 3 passing through the perforations on the flange male disc 1 and the flange female disc 2, and the depth of the insertion and locking of the flange male disc 1 and the flange female disc 2 is locked within a predetermined range through the cooperation of a nut and the threaded rod 3.

[0025] Specifically, the flange male disc 1 in the above embodiment comprises a first connecting cylinder 11, and the flange female disc 2 comprises a second connecting cylinder 21; during assembly, the first connecting cylinder 11 is inserted into the second connecting cylinder 21, and then the threaded rod 3 is sequentially passed through the perforations on the flange male disc 1 and the flange female disc 2, and then the threaded rod 3 is screwed with the nut, so that the depth of the insertion and locking of the flange male disc 1 and the flange female disc 2 is increased, and thus the rubber sealing ring 4 fixedly arranged at the end section of the first connecting cylinder 11 is in contact with the abutting ring member 5 arranged in the second connecting cylinder 21, and the rubber sealing ring 4 is deformed to fit the abutting ring member 5 and the inner wall of the second connecting cylinder 21.

[0026] In the above technology, the insertion and locking form is adopted, and the depth of the insertion and locking of the flange male disc 1 and the flange female disc 2 is locked within a predetermined range through the cooperation of a nut and the threaded rod 3, so as to realize the sealing of the power well.

[0027] As a further provided embodiment of the utility model, in combination with Figure 2 As shown in the figure, the contact side of the rubber sealing ring 4 and the abutting ring member 5 is divided into a horizontal surface and an inclined surface according to the structure, the included angle between the horizontal surface and the inclined surface is obtuse, and the inclined surface is adjacent to the outer side of the rubber sealing ring 4.

[0028] Specifically, the rubber sealing ring 4 in the embodiment is a hollow structure, and when the depth of the insertion and locking of the flange male disc 1 and the flange female disc 2 is increased, the rubber sealing ring 4 is in contact with the abutting ring member 5 and is deformed, and due to the special structure of the contact surface, the rubber sealing ring 4 is deformed and moves away from the center.
