The staff connects the first flange joint to the flange and connects the second flange joint to the pipe, thereby reducing the gap between the pipe and the flange without losing tightness.

[0004] In actual use, when the first flange joint and the second flange joint are docked, the sealing gasket enters the sealing groove. In order to ensure its sealing effect, it is often necessary to control the connecting screw for tightening. Since the pressure resistance of the sealing gasket is limited, if the staff controls the connecting screw to rotate excessively, the sealing gasket will be under excessive pressure, which will reduce the service life of the sealing gasket.
