AI Technical Summary
During long-term operation, the nuts at existing fire-fighting pipeline connections are prone to loosening due to factors such as water flow impact and vibration, resulting in poor sealing and a risk of leakage.
The system employs a worm gear drive structure, with the internal threaded cylinder connected to the bolt rod via a threaded connection. Utilizing the self-locking characteristics of the worm gear and worm, it ensures the stability and sealing of the pipeline connection, preventing loosening.
It achieves long-term stability and sealing of fire protection pipeline connections, prevents loosening caused by vibration or external impact, and ensures the reliability of pipeline connections.
