AI Technical Summary
Existing sealing flanges experience a decline in sealing performance over prolonged use, and vibration can cause connections to loosen, resulting in poor sealing and necessitating downtime for maintenance.
The injection tank is filled with sealant, and waterproof and anti-corrosion rings are used to prevent the seal from deteriorating. The tightening screw and sealing ring are used to prevent vibration from loosening, and the pipe is quickly connected using an external connecting ring.
It improves the sealing effect, prevents the sealant from deteriorating due to moisture, avoids loosening caused by vibration, and achieves quick connection and good sealing performance.
