AI Technical Summary

Benefits of technology

This technology allows for simulations where leaks occur during storage or transportation from an accidental rupture (a bursting) caused by external factors such as vibrations that may cause damage to equipment like pipes used with this system. By adding a special apparatus called stopping valves between different locations within the pipeline, it becomes possible to simulate these events without causing any harm if they happen again later due to normal use conditions.

Problems solved by technology

This patented technical problem addressed by this patents relates to preventing leaks or plugs caused when storing and transferring liquified Natural Gas (LNG), particularly at higher pressure levels than usual.

Abstract

The invention relates to a low temperature liquefaction vehicle fuel tanker operation box pipeline equipment plugging simulation test bench. The bench includes a pipeline, a first shut-off valve, a second shut-off valve, a shut-off valve-pipe elbow connection plugging device and a shut-off valve stem plugging device, the first shut-off valve and the second shut-off valve are installed in the pipeline, an elbow connection structure is formed between the first shut-off valve and the pipeline, the pipeline is connected with a liquid nitrogen bottle, the shut-off valve-pipe elbow connection plugging device is installed at the elbow connection of the first shut-off valve and the pipeline, and the shut-off valve stem plugging device is mounted on a valve stem of the second shut-off valve. The bench can conduct simulating experiment on the leakage plugging of the internal shut-off valve of a liquefied natural gas tank car operation box, a pipe elbow joint and the shut-off valve stem, and achieve the purpose of verifying the plugging effect.
