Description

Technical Field

[0001] The utility model belongs to the technical field of tight sealing flanges, and particularly relates to a comb-tooth type combined sealing precision flange. Background Art

[0002] Flange is a commonly used connector, which is often used in occasions such as pipeline connection and equipment connection, so that pipelines and equipment can be conveniently connected. Common flanges will be equipped with corresponding gaskets, sealing rings, etc. for sealing operations when they are connected, so as to improve the sealing performance between flanges after connection, prevent the leakage of liquids flowing through flanges during use, and cause unnecessary problems and possible safety accidents. However, due to its structural limitations, the sealing performance of common flanges after connection is difficult to guarantee, and there are often small leaks. Moreover, as the use time increases, the impact force of the liquid inside the flange will reduce the sealing performance between the flanges, resulting in the expansion of the leakage site. Different repair methods will be adopted according to the actual situation for these problems, such as applying sealant at the leakage site, re-connecting the flange, etc. These methods will increase the corresponding manpower and other costs.

[0003] Secondly, during the repair process, the delivery of liquids, etc. needs to be stopped, and it needs to wait until the repair is completed before it can be used again. This causes a certain waiting time and has a certain impact on the completion of normal delivery tasks.

[0004] In summary, there are some problems in the use of flanges with poor sealing performance, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
