AI Technical Summary
Existing sealing devices cannot meet the requirements of high pressure stability, durability and ease of operation under complex working conditions in bentonite slurry anti-dispersion performance tests. They have problems such as uneven stress on the sealing surface, easy fatigue failure and complicated operation.
The composite sealing structure includes a first sealing component, a second sealing component, an anchoring component, and a support and positioning component. It utilizes EPDM sealing rings and silicone sealing gaskets to form a double-layer heterogeneous seal. Combined with the anchoring component of the anchor rod and anchor rod fixing seat, and with the help of elastic washers and gaskets, it can achieve rapid and uniform compression and dynamic compensation of small gaps in the sealing surface.
It achieves long-term stable high-pressure sealing in dynamic water environment, simplifies operation process, improves the consistency and reliability of sealing state, prevents leakage, and meets the requirements of bentonite mud anti-dispersion performance testing in complex environment.
