Description

Technical Field

[0001] This utility model belongs to the field of sealing technology, and specifically relates to a fluid sealing device. Background Technology

[0002] Fluid seals play a crucial role in fluid transport systems. However, traditional fluid seals have many shortcomings in structure and performance, making it difficult to meet the increasingly complex and diverse needs of industrial applications.

[0003] Traditional fluid seals typically employ a single sealing structure, such as rubber rings or packing seals. These methods are prone to inadequate sealing and leakage when handling high-pressure, high-flow-rate fluids. Rubber rings are susceptible to aging and wear, resulting in a short lifespan and frequent replacements, increasing maintenance costs and downtime. Packing seals require significant clamping force, which can cause wear on shafts or pipes, impacting equipment efficiency and lifespan. Furthermore, traditional fluid seals rely on limited connection methods, often employing welding. While welded connections are robust, they are difficult to disassemble and repair. Problems require cutting and re-welding, making installation and disassembly cumbersome. Moreover, bolts can loosen over time, leading to decreased sealing performance. Therefore, a new fluid seal is needed to address these issues. Utility Model Content
