Structural characteristics
D-type rotary joint adopts rolling bearing support, good rotary flexibility, after installation of rotary joints run more smoothly and safely, sus304 material bellows compensator, the spring is not in contact with the working medium, so that the seal is more stable and reliable, double-plane sealing ring floating by the locating sleeve positioning in the hollow shaft, and with the compensator and the composition of the double-end sealing friction vice, the spring at any time to provide the sealing of the end face pressure required. In order to facilitate the observation of the sealing ring wear and sealing condition, the shell is equipped with observation holes. This product is used in cold water, hot water, oil, air and other media. There are unidirectional, bi-directional internal solid type, bi-directional internal rotary type, the speed can be up to 500r/min, but the maximum speed depends on the installation type, diameter and pressure and other factors. Mainly used in rubber, plastic, chemical industry.

Dd-F type one-way flow-through - flange connection
