Embodiment Construction

[0047] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0048] Figure 1 to Figure 7 An embodiment of the sealing clip provided by the present invention is shown.

[0049] figure 1 Shown is the schematic diagram of the sealing clamp 1 application. The sealing clamp is used to connect the first pipe fitting 2 and the second pipe fitting 5, and the ends of the connection positions of the first pipe fitting 2 and the second pipe fitting 5 that need to be sealed and connected have a flange structure, which is called the first flange 3 And the second flange 6. The opposite sides ...

Abstract

The invention discloses a sealing hoop. The sealing hoop is used for being connected with pipe fittings in a sealing mode, and the ends of the pipe fittings are provided with matched flange plate structures. The sealing hoop comprises a hoop body and hoop lateral walls, wherein the hoop body is matched with the outer edges of the two matched flange plates in the peripheral direction, the hoop lateral walls are oppositely arranged on the hoop body and extend inwards in the radial direction, the hoop body and the two hoop lateral walls define a limiting through groove, the inside space of the limiting through groove is used for containing the two flange plates, the distance between the two hoop lateral walls in the axial direction of the hoop body is called as limiting distance, and the position of the minimum limiting distance is closer to the axis of the hoop body compared with the position of the maximum limiting distance. The sealing hoop is divided into at least two parts in the peripheral direction, and the divided parts are connected end to end and are fixedly connected into a whole through connecting pieces. The structure of the limiting groove body enables both radial pressure and the opposite axial pressure to be applied to the two flange plates needing connecting under the action of the sealing hoop, so that the two discs are compacted and the sealing performance is reinforced. The split structure enables the sealing hoop to be installed conveniently and operated easily.

Description

technical field [0001] The invention relates to a sealing connection device for pipe fittings, in particular to a sealing hoop. Background technique [0002] Pipeline transportation is widely used in the transportation of fluid media such as water, fuel oil and gas, such as tap water pipelines, natural gas pipelines and working medium pipelines in compressors. Pipeline transportation has the advantages of low cost, good continuity and high safety. [0003] Due to the limitations of practical conditions such as transportation route and transportation distance, pipeline transportation is difficult to be completed by a single pipe fitting, and corresponding pipe fittings are required to regulate the transportation task during the pipeline transportation process, so the pipeline transportation system often requires multiple and multiple pipe fittings to connect made. [0004] The connection between pipe fittings should not only ensure the sealing and safety of the pipeline, bu...
