BELLOWS COMPENSATOR FOR CHANNEL-FREE LAYING

摘要

FIELD: machine building. ^ SUBSTANCE: bellows compensator is installed in case and is equipped with guides welded to branches of compensator. Pipes with packed surface A are fixed on both sides of the compensator on its branches. On pipes under the case there are arranged by two flanged collars forming space between them. Flanges of the collars are directed towards each other. Space between the collars is filled with filler. As filler there is used consistent material possessing lubricating and water repellent properties. The flanged collars contact soil and are equipped with a scraper adjacent to packed surface A of the pipe. The collars are set mainly at distance L one from another. Distance L exceeds or is equal to value of compensator transfer. ^ EFFECT: increased reliability of pressure tightness and operability of bellows compensator. ^ 1 dwg
