ていた。(Prior Art) Conventionally, various rotary joints have been known, and generally, a mechanical seal or an elastic body is provided between a fixed portion and a rotating portion to achieve sealing to prevent leakage of a fluid flowing in a pipe. However, in the case of a rotary joint, since the fixed portion and the rotating portion slide, it is difficult to completely seal the portion even with a mechanical seal, and it is impossible to completely prevent the passage of gas. Can not. Therefore, there is a tendency for the outside air to be sucked into the joint due to the negative pressure phenomenon in the pipe when the fluid flows, and bacteria in the air may invade. Therefore, for example, when aseptic water for cleaning is sent to the cleaning nozzle provided in the rotating turret of the container cleaning machine in a canister or bottle aseptic filling line, it is possible to completely prevent infiltration of bacteria at the joint part. In rare cases, bacteria could infiltrate, hindering the supply of completely sterile water.

も良い。The rotary joint of the present embodiment is configured as described above, and the flange 4 formed on the fixed side tube side portion, the rotary side bearing casing 7 and the tubular casing 5 are connected to form a tubular joint casing. A sealed sterile medium chamber 9 is formed so that the first and second mechanical seals 10 and 13 are located at both ends of the sealant while being completely shielded from the outside. By supplying steam and discharging it from the discharge port 22 to constantly circulate steam to fill the inside of the sterile medium chamber with steam, the chamber is sterilized and a sterile barrier layer is formed on the outer peripheral portion of the mechanical seal portion. Therefore, even if a negative pressure is generated in the pipe due to the fluid flowing in the pipe, outside air does not come into direct contact with the sliding contact portion, so that bacteria can be completely prevented from entering the pipe. And since it uses steam as a sterile medium,
There is also no risk of the odor of the sterilant being transferred to the fluid flowing in the pipe as in the case of the sterilant. This is especially important, for example, when supplying aseptic water into a container via a rotary joint for cleaning the container in an aseptic filling system for food. Note that instead of always using steam as a sterile medium, for example, the steam is supplied to the sterile medium chamber before the operation of the device to sterilize the sterile medium chamber, and the steam is supplied to the sterile medium chamber before the operation of the device to perform sterilization. The medium chamber may be sterilized and sterile water may be supplied as a sterile medium instead of steam during operation of the apparatus.
