A power-assisted pipeline valve, including a valve body and a pressure relief assembly. A top of the valve body is provided with a first chute. A sliding sleeve is disposed in the valve body and has two sides respectively connected to an inner wall of the valve body through a first spring. A ball valve assembly is disposed in the sliding sleeve and connected to a valve stem. The valve stem passes through the sliding sleeve and is sleeved with a sliding shell, and the sliding shell is disposed in the first chute and provided with a rack and an electric power-assisted mechanism which is connected to the valve stem. The top of the valve body is penetrated by a first rotating shaft which is orderly sleeved with a fifth gear, a rotary table and a third spring from top to bottom. The fifth gear is meshed with the rack. The rotary table is connected to the fifth gear through a centrifugal locking mechanism. The third spring is connected to the rotary table and the valve body respectively. The pressure relief assembly is disposed on the valve body and connected to the rotary table. The present disclosure effectively solves the problems in the prior art that it is laborious for a person with a small strength to operate a manual valve, and a water hammer prevention effect is poor, which seriously affects the service life of the manual valve.
