What's the bottom filling of the storage tanker trailer?

(1) Bottom loading system of the storage tanker trailer

In the previous fuel tank semi trailer, we pour oil into the tank from the manhole above the tank trailer.Add a special oil pump at the rear of the petrol tanker trailer to realize the reverse loading and unloading of diesel.

Now, in order to improve the safety, our fuel tank trailer production has all done the bottom filling process.

What is bottom filling? Important components for bottom filling: The main components of bottom filling are exhaust gas recovery system, anti-spill system, subsea valve, European standard tank mouth, control head, SO2 socket, anti-static system, bottom canned API connector.

(2) European standard aluminum alloy tank cover

Aluminum alloy European standard tank cover is also manhole cover. It's usually on the top of the oil tank, the tank cover has built-in breathing and emergency exhaust functions. Our diesel trailer has oil and gas recovery valve, oil measuring hole, anti-overflow probe on the manhole cover, etc.

During the filling process of the anti-overflow sensing system, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the loading of the oil.

The built-in breathing valve keeps the internal pressure of the fuel tank trailer stable and balanced with the external pressure when transporting oil.

Its spill-proof design prevents tanker trucks from being sealed in the event of an accident.

When the pressure of the emergency exhaust device in the fuel tank rises sharply, it will automatically open to release the pressure in the fuel tank, thereby preventing accidents and greatly improving the safety of oil transportation.

(3) Subsea valve

Subsea valve(emergency shut-off valve). Simple operation, time saving, safety and environmental protection.

Pressure-balanced subsea valve is used for multi-compartment tanker trucks, which can carry out separate loading and unloading of different tanks. The three-way design simplifies the pipeline, reduces the load, easy to operate, and safe and reliable.

The pneumatic shut-off valve is installed at the bottom of the tanker tank and can be refueled. The internal pressure of the valve is small, the flow is large, and there is a cut-out groove on the flange of the valve body.If the force is too large, the car body pipeline and the tank body will be automatically disconnected, and the automatic centering plunger and durable spring will still remain sealed, and the medium in the tank will not leak, thereby ensuring the safety of the oil tank.

When we can't open because there is no air source or other reasons, we can open the cylinder piston rod and open it manually.
