Description

Technical Field

[0002] The pipe joint sealing structure is a structural design used to connect pipes and ensure that the joints are sealed without leakage. However, the current pipe joint sealing structure has the problem that most of the pipe joint sealing structures currently used are single-layer sealing in actual use. When facing complex use environments and high pressures, the sealing performance of the single-layer sealing structure is often difficult to be fully guaranteed. Once disturbed by external factors, such as temperature changes, pipe vibrations, etc., it is easy to fail to seal, leading to leakage problems. This is because there is a lack of multi-layer sealing components. The lack of multi-layer sealing components will not only lead to the above problems, but also the limitations of the single-layer sealing structure also limit its application in some special fields, and cannot meet the sealing requirements of higher standards. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
