Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described in the following in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A pipe coupling assembly according to an embodiment of the present utility model will be described in detail with reference to fig. 1 to 3.

Examples:

the pipeline connecting assembly provided by the embodiment of the utility model, referring to fig. 1 and 2, comprises two pipelines 1, wherein flange plates 2 are welded at the end parts of the two pipelines 1, mounting holes 3 are formed in the two flange plates 2, bolts 4 are inserted into the mounting holes 3, and the two flange plates 2 are locked together by inserting the bolts 4 into the mounting holes 3, so that the two pipelines 1 are connected together.

Referring to fig. 2, a third sealing ring 10 is provided between the inner connection joints of the two flanges 2, and the third sealing ring 10 is used to seal the connection joints of the flanges 2, thereby preventing leakage of the liquid from the pipe 1.

Referring to fig. 2 and 3, a first sealing ring 5 is provided between the outer connection joints of the two flanges 2, and the structure can seal the outer connection joints of the flanges 2 by using the first sealing ring 5, thereby preventing external moisture from penetrating into the bolts 4 from the gaps of the flanges 2 and protecting the bolts 4.
