Detailed Description

The technical solution of the present invention is further illustrated by the accompanying drawings and examples.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As shown in the figure, the first-aid repair joint for the RTP pipeline comprises a first joint 1 and a second joint 2 which are positioned on adjacent pipelines, and the first joint 1 and the second joint 2 are used for realizing stable connection between the pipelines. The first joint 1 and the second joint 2 both comprise an inner core 3 and a snap ring 4 which are respectively positioned inside and outside the pipeline, and the positions of the inner cores are fixed because the pipelines are installed, and the inner cores 3 are extruded into the pipelines by utilizing the space between the pipelines. The outside of inner core 3 is equipped with second barb 8, and second barb 8 prevents that the pipeline from deviating from. A circular sealing ring 9 is arranged in a groove between the second barb 8, and the sealing ring 9 improves the sealing property between the second barb 8 and the pipeline.

The outer edge of snap ring 4 is frustum structure, and the outside of snap ring 4 is equipped with the sleeve 5 of frustum structure for snap ring 4 is connected with sleeve 5 through the conical surface. The snap ring 4 and the tail end of the pipeline are positioned on the same vertical line, so that the overall sealing performance is improved conveniently. The inboard of snap ring 4 is equipped with the first barb 7 of horizontally, and first barb 7 guarantees to be connected with the stability of pipeline, prevents that the pipeline from deviating from. The first barb 7 is opposite to the second barb 8 in direction, so that the stable connection of the whole body and the pipeline is ensured. The diameter of the inner edge of the sleeve 5 is smaller than the outer diameter of the bottom of the snap ring 4, so that stable connection of the sleeve 5 to the snap ring 4 is guaranteed. Or the snap ring 4 is of a split structure, and pipelines with different calibers are connected by reversely moving the sleeve 5 and the snap ring 4.

The outer side of the sleeve 5 is provided with a flange 6 connected to the outer extension part of the inner side of the sleeve 5, so that the flange 6 is fixed. The flange 6 protrudes from the sleeve 5 and is connected between its outer edges by a locking bar 13. The first joint 1 is connected with the second joint 2 through the flange 6, so that stable connection between the first joint 1 and the second joint 2 is ensured.
