Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a rotary connection device for rotatably connecting a supply hose for transporting and supplying a fluid such as acid, alkali chemicals or organic solvents.

The rotary connection device of the present invention is a cylindrical body 12 of the first and second body parts 10 and 20 of the metal material to form the connecting flange (11, 21) in the side as shown in Figures 1 to 4 (22) inside and outside,

The ball 25 is inserted through the ball insertion hole 23 in at least one pair of ball grooves 24 formed on both circumferences between the cylindrical bodies 12 and 22 to rotate in a mutual cloud.

Particularly, the metal first and second body parts 10 and 20 have a contact surface in contact with a chemical fluid of acid and alkali on the inner side of the cylindrical bodies 12 and 22 and the outer side of the connecting flanges 11 and 21. Assemble and install the first and second contact blocks 30 and 40 made of Teflon, which are formed to face the flanges 31 and 41 on the side to block the inner and outer sides,

Teflon O-rings 51 and linings 52 are installed on both sides of the circumference between the cylindrical bodies 12 and 22 of the first and second body portions 10 and 20 in the ball outward position. It is configured to install at least one O-ring 51 'on the circumference between the first and second wetted blocks 30 and 40 to reduce the airtightness and reduce the friction coefficient.

In addition, on both circumferences between the cylindrical bodies 12 and 22 of the metal first and second body parts 10 and 20, as illustrated in FIG. 5, the O-ring 51 of the Teflon material is located at the inner side as well as the outside of the ball. ) And linings 52 can be configured to face each other to reduce airtightness and friction coefficient.
