DEVICE FOR PRESSURIZED PIPELINE

摘要

A cleaning device of a pressure-type pipeline is provided to cut down the cost for a cleaning operation and to prevent the inner peripheral surface of the pipeline from being damaged. The cleaning device of a pressure-type pipeline comprises a tee trap, a pig, and a pig guide unit(300). The tee trap includes the direct pipe formed with an insertion port, and the branch pipe branched off from the both directions of the direct pipe to transfer fluid. The pig is transferred forcibly along the tee trap and the pipeline to remove the foreign material of the pipeline and formed with the plastic brush positioned at the circumference thereof. The pig guide unit is installed at the inside of the tee trap to transfer the pig forcibly toward the branch pipe from the direct pipe and to guide the pig. The pig guide unit includes a stopper(310), an extension unit(330), and a guide unit(350). The stopper is corresponded to the insertion port of the direct pipe. The extension unit is extended toward the branch pipe from the stopper. The guide unit is rounded toward the branch pipe from the end portion of the extension unit.
