The swivel joint with flexible rotation and good sealing is connected in series with the pipeline, and it is used for the equipment for liquid medium transmission between the tanker and the storage and transportation pipeline of the trestle. The key component, the rotary joint has a built-in double raceway support structure, which is flexible in rotation, light and reliable. The outer ring is made of alloy steel, and the inner ring is made of stainless steel or lined with PTFE to ensure that it can be used safely and reliably in high temperature, low temperature, and strong corrosive media. The sealing ring is made of reinforced polytetrafluoroethylene material, lined with stainless steel elastic support ring, and the seal is polished, which has excellent self-lubrication and super corrosion resistance.
Application: the liquid phase pipeline interface of the closed loading and unloading operation on the top of the train is downward
Applicable medium: liquefied petroleum gas, liquid chlorine, liquid ammonia, etc.
Working pressure: 1.0Mpa 1.6Mpa 2.5Mpa
Pipe material: carbon steel/stainless steel/aluminum
Nominal diameter: DN50-DN150
Features:
1. The swivel joint with double raceways and the sealing ring with elastic card ensure that the loading and unloading medium does not leak;
2. The spring cylinder balancer which is balanced at any time makes the loading and unloading arm easy to operate and labor-saving;
3. During the loading and unloading process, follow the tank car within the normal moving range of the tank car;
4. When the loading and unloading arm is in the storage state, the lock is parallel to the traveling direction of the tanker, and the space occupied is small;
5. The structure is reasonable, and the smallest arm size meets the most reasonable envelope range.
