Beschreibung
Zusammenfassung:	The invention provides pressure tapping and blocking shunting equipment. The pressure tapping and blocking shunting equipment mainly comprises a tight coupling mechanism, a blocking mechanism and a tapping device. The tight coupling mechanism comprises a lower valve body, an upper valve body and a sealing box body. The lower valve body and the upper valve body are both matched with the outer wall of a pipeline to be repaired. The upper valve body and the lower valve body are in bolted connection, and the pipeline to be repaired is tightly clamped between the upper valve body and the lower valve body in the axis direction. The lower end of the sealing box body communicates with the upper valve body. The blocking mechanism is arranged inside the sealing box body. The driving end of the tapping device can stretch into the sealing box body so that the pipeline to be repaired can be tapped. The pressure tapping and blocking shunting equipment has the beneficial effects that the blocking mechanism is assembled into
