Chemical device delivery line coupling device

The present invention relates to a pipe coupling device, and more particularly to a coupling device for a chemical delivery pipe that can isolate internal and external pipes to improve their durability.

According to the conventional chemical delivery pipeline structure, since the chemical agent may have high corrosivity, toxicity, or environmental pollution, the chemical delivery pipeline is transported by an inner tube and is disposed on the inner tube. There is an outer tube to form isolation protection. When the inner tube is damaged or leaked, the outer tube can reduce the damage and loss caused by the external leakage. However, it is not difficult to find out that the above-mentioned conventional structure has some shortcomings, mainly The reason is as follows: the inner tube is directly inserted inside the outer tube. If the length is too long and the gravity of the inner tube causes the outer tube to contact, when the fluid flows through the inner tube, the inner tube is subjected to the pressure of the fluid and Fluctuations can cause vibration and expansion and sloshing, causing the inner tube to continuously rub the outer tube, which not only generates flow noise, but also makes the friction part thin and damaged. At this time, the fluid will be easily leaked, which will cause a hazard. The cost of replacing the pipeline is the problem that the creative is trying to solve.
