The utility model is also characterized in that the pipe tongs (1) is of an upper and lower semicircular structure and is tightly fixed with the pipe through 2M 24 × 130 bolts, the distance between the two fixed pipe tongs is 8-10mm, and 8 phi 26 bolt holes are evenly distributed in the circumferential direction.
The utility model discloses a characteristic still has: top cover (2), its characterized in that: the gap between the inner diameter of the sealing step and the outer wall of the pipe is 0.5mm, and the gap between the outer diameter of the sealing step and the inner wall of the sealing step of the sleeve (4) is 0.5 mm.
The utility model discloses a characteristic still has: drum-shaped sealing washer (3), its characterized in that: the drum-shaped sealing ring (3) is made of polyurethane, the gap between the inner diameter of the drum-shaped sealing ring and the outer wall of the pipe is 0.5mm, and the gap between the outer diameter of the drum-shaped sealing ring and the inner wall of the sealing step of the sleeve (4) is 0.5 mm.
The utility model discloses a characteristic still has: sleeve (4), characterized in that: the ring plate is formed by welding three parts, namely a ring plate, a sleeve and a blocking plate, steps are assembled on the inner diameter and the sealing surface of the sleeve after welding, and 8 bolt holes with the diameter of 26 mm are machined in the ring plate.
The utility model is also characterized in that the double-end stud M24 × 130 is 2 pieces, the M24 nut is 4 pieces.
The utility model is also characterized in that the double-end stud M24 × 210 is 8 pieces, the M24 nut is 16 pieces.
