Product Description

Maintenance free rotary compensator connector directly sold by manufacturer


The rotary compensator is composed of reducer, inner sleeve, outer sleeve of sealing seat, flexible graphite packing, nut bolt spring combination and packing gland, and is equipped with corresponding ball. The rotary compensator uses the sealing material to be molded with a press, and the molding density is not too dense to maintain the plasticity. Then put n rings of the packing ring (determined according to the product requirements) into the packing chamber, add some components to delay oxidation, and then use the hydraulic press to carry out secondary molding under a certain pressure (the hydraulic press surpasses the manual wrench process in strength and uniformity), so as to integrate the packing rings, so as to improve the density of the packing and improve the sealing performance of the packing, Ensure that the product will not leak within 15-20 years.


Performance of rotary compensator


Rotary compensator is mainly used for large distance compensation. In the three-dimensional pipe network and spatial network, fixed support is not required at the turning of the pipe network, but the angle of the rotary compensator is used to absorb the heat expansion and cooling contraction in the pipe network, which is simple, convenient and low cost.

The rotary compensator is composed of a rotary inner cylinder, a packing gland, a fastening flange, a spring flange, a spring, a guide centering ring, a shaped flexible graphite sealing packing, a sealing pressure ring, a sealing seat shell, an end connecting pipe, a bolt and a nut. The rotary compensator features no thrust, maintenance free, large compensation and no leakage.
