[0029] As a further implementation of the present scheme, the positioning disc 31 and the socket welding flange body 1 are located on the same central axis, the number of the positioning hole 32 is four, and the four positioning holes 32 are evenly distributed in a circumferential array on the outer wall of the socket welding flange body 1. Such a layout can position the socket welding flange body 1 from multiple directions, ensuring the reliability of positioning.

[0030] As a further implementation of the scheme, the number of limiting screw 35 is set to four, and the limiting screw 35 is located between two positioning holes 32. The four limiting screw 35 is evenly distributed in a circular array. The outer wall of the limiting disc 34 is fixedly provided with an adapter seat 36 for sliding with the limiting screw 35. The position of the adapter seat 36 corresponds to the position of the limiting screw 35.
