AI Technical Summary
When existing clamps are connected to flanges, uneven surfaces or deformation can lead to poor sealing and sealant leakage. Furthermore, they are prone to tilting under high pressure, making it impossible to effectively control leaks.
Design an irregular clamp with V-shaped annular grooves on both the upper and lower end faces and triangular comb-tooth annular grooves on the inner wall. Combined with V-shaped sealing rings and triangular comb-tooth sealing rings, the clamp improves the fit and friction between the clamp and the flange, ensuring sealing performance, and simplifies the sealing process through the glue injection hole.
This achieves a tight fit between the clamp and the flange, preventing sealant leakage, improving the sealing effect, preventing clamp misalignment, and ensuring safety and sealing performance.
