The Function Of Fuel Tanker Truck Subsea Valve

The main role of the tanker truck subsea valve is to effectively absorb the vehicle by the impact of damage to the pipeline transmitted energy, and also ensure that the integrity of the sealing mechanism, to avoid material leakage, in order to ensure the safety of the entire vehicle, greatly improving the safety of driving security. subsea valve, also known as emergency shut-off valve, is a safety device installed at the bottom of the tanker truck tank. It is designed to improve the safety of transporting hazardous materials. The subsea valve has several key functions:

 

1. Absorb Impact Energy

 

In the event of an accidental collision of a tanker truck, the rupture groove set at the root of the shell of the subsea valve can effectively absorb the transferred energy and disconnect the valve body along the cut-off groove, thus realizing the separation of the piping under the truck and the tank, ensuring the sealing of the tank and avoiding the leakage of internal materials.

 

 

2. Preventing Material Leakage 

 

By keeping the sealing of the tank, the subsea valve prevents the leakage of oil or other dangerous materials inside the tank, thus ensuring the safety of transport.

 

 

3. Emergency Shut-Off Function 

 

In case of leakage and other emergencies, the emergency shut-off valve can be closed manually or by using a fusible plug that automatically melts when a fire breaks out, thus playing a role in personal safety protection.

 

 

4. Improvement Of Transport Safety

 

The design and material selection of subsea valves (e.g. aluminium alloy, stainless steel, etc.), as well as the precautions for their installation and maintenance, are all aimed at improving the safety of transporting dangerous goods. For example, the design of the fully pneumatic control ensures that the valve can still close properly in the absence of an air source, while the auto-centering design of the sealing stem ensures a strong, durable and efficient seal.
