AI Technical Summary
The unloading device of the existing ammonia water transport tanker has an integrated structure and cannot automatically relieve pressure during the ammonia water transport process, resulting in excessive pressure inside the pipeline, which can easily cause pipeline rupture and ammonia water leakage.
An ammonia water unloading device is designed for unloading ammonia from ammonia water transport tankers. By installing pressure relief pipes and branch pipes on the top and left sides of the delivery pipe, when the internal pressure of the delivery pipe is too high, the high-pressure gas pushes the blocking disk and sealing disk movement, the gas flows into the pressure relief pipe and branch pipes, and is discharged from the exhaust hole to achieve automatic pressure relief.
Effectively prevent excessive pressure on the transportation pipeline, avoid the rupture of pipelines and leakage of ammonia water, improve the safety of the ammonia removal process, and enhance the diversity and practicality of the pressure through the manual pressure.
