Zusammenfassung:	The utility model provides a pipeline valve dismounting and mounting auxiliary device which comprises an upper pipe hoop and two first fixing plates symmetrically fixed to the two sides of the upper pipe hoop. The lower pipe hoop is positioned on the bottom side of the upper pipe hoop; the two second fixing plates are symmetrically fixed to the two sides of the lower pipe hoop and arranged on the bottom sides of the two first fixing plates in parallel. The two adjusting rods are symmetrically arranged on the two sides of the upper pipe hoop, and any adjusting rod vertically penetrates through the first fixing plate and the second fixing plate; the two adjusting nuts are connected to any adjusting rod in a threaded mode and located between the first fixing plate and the second fixing plate. According to the pipeline valve dismounting and mounting auxiliary device, the jacking pressure of the first pipeline and the second pipeline on the valve is relieved by adjusting and rotating the adjusting nut, so that the
