Yu-xiang maintenance-free rotary compensator seal packing uses the most advanced packing, the temperature of -60 ℃ -800 ℃, due to the retaining ring within the casing of the compensator external and within the jacket pipe weld two retaining ringfitted to reduce friction (rolling ring) ball, reducing the wear of the inner sleeve seal packing. Due to the compensatordevice springs naturally Zhang pushing and pressing the packing gland flange wear very minor gland packing is always in a compact state, so that the liquid or gaseous media in the pipeline leak, when the filler amount of wear large, spring tension, unable to meet the adjustment of available external compression of the spring to adjust so as to achieve to reach the required sealing effect stopped working condition, so this product to overcome the lack of other similar products, the original rotary casing compensation when the packing wear and tear can not get timely compensation adjustments resulting in the sealing performance of the compensator down until the leak, and packing wear large amount of products must be removed from the pipeline to open the fed-filler thus affect the operation of the pipeline, the impact of user of normal production.
Compensator of the maintenance-free use of the inner tube and adjustable tube the same diameter, so that the media be able to smooth, smooth flow to solve the above problems. Some similar products, the use of the adjustable tube leaving the product at work due to the adjustable vortex of media production, and generate a pressure loss in flow rate slows down the flow resistance to the media.
