Necessity Of Pull Off Valve For Tank Truck Loading And Unloading

Pull off valves play a very important role in oil transportation, and today, Editor Hua De will discuss the necessity of them together.
Due to the characteristics of flammability, explosiveness, and strong corrosiveness of many chemical products, there are significant risks in the storage and transportation of chemical products. Negligence can easily lead to accidents such as fires, explosions, and environmental pollution. Major accidents can have a significant negative impact on social safety. Therefore, with the development of society and economy, as well as the increasing requirements of the country for environmental protection, the safety and environmental management requirements for chemical enterprises have become increasingly strict. Therefore, relevant production enterprises have gradually introduced emerging safety equipment and devices into the production line to ensure safety standards, explicitly mentioning the need to set up rupture devices on pipelines, which is commonly known as rupture valves.
Why install a breakaway valve?
If the following unexpected situations occur:
Due to operational errors or sliding reasons, the tank truck left the work area before being separated from the hose (or equipment), causing a large amount of raw material leakage and causing a major safety accident by pulling and breaking the connecting pipe; When the tank truck is loading and unloading, if there is a sudden fire or other reasons on site, it is necessary to quickly evacuate the site. If the tank truck and loading arm cannot be separated using normal methods, it can also lead to major personal and property safety accidents, causing economic losses and environmental pollution. To prevent accidents and reduce accident losses, equipping loading and unloading equipment with emergency release pull off valves is a major measure to ensure the safety and environmental protection of the storage and transportation process of petrochemical raw materials.
Pull off valves are used to install on the loading and unloading hoses or equipment of chemical raw materials (such as liquid propane, ammonia, ethylene oxide, liquefied petroleum gas LPG, butadiene, industrial methanol, natural gas LNG, liquid chlorine, carbon dioxide) in tank cars (trains, cars). Under normal working conditions, when subjected to a certain external force, the emergency disconnect valve will automatically and safely disconnect, and both ends will automatically close without fluid leakage, protecting the safety of pipelines and equipment. The pull off valve ensures the maximum safety of the fluid conveying process during fluid loading and unloading.
