Semi Trailer Tank European System

The European system of the tanker includes:

  • Bottom loading and unloading system

  • Exhaust gas recovery system

  • Anti-overflow system

As the below picture shows:


  • The three identical valves on the left (with the handle facing up on the right side of the valve body) are the lower loading/unloading valves, one for each bin.

  • The valve on the far right without a handle is called the oil and gas recovery joint, one for each vehicle.

  • The blue one in the upper part of the valve box is called the anti-overflow probe socket.

  • The upper part of the right side of the valve box is the subsea valve air control combination switch, the three warehouses are four switches, the left side is the main switch, and the right side is the one, two and three warehouse switches.

  • The red one on the far left is the reverse electrostatic reel, which is used to reverse static electricity when loading and unloading, and has nothing to do with oil and gas recovery.

  • The two switches on the upper part of the valve box are the active guardrail switches, and the active guardrail switches are the switches of the top pneumatic guardrail. Not directly related to oil and gas recovery.


  • This is an aluminum alloy explosion-proof manhole cover

  • The long switch is a small hole cover, which can be opened for loading.

  • The blue wire harness is the anti-overflow probe, which is used to detect whether the liquid level reaches the probe position when filling the material. It is used in conjunction with the anti-overflow socket, and the wire harness is connected to the anti-overflow socket.

  • The white installation holes are for the oil and gas recovery valve. The oil and gas recovery valve is the same as the manhole cover. There is one for each bin. The oil and gas recovery valve can be installed on the manhole cover (the oil and gas recovery valve installed on the manhole cover is as shown in the above picture The blue label shown with black probe) can also be installed on the tank (as shown in the picture below, it is installed on the tank). Recover the gas in the tank. The small black cover on the manhole cover is on the mounting hole for the dipstick.

  • The breathing valve is installed on the tank next to the manhole cover, and some customers need to install it additionally. The general aluminum alloy explosion-proof manhole cover comes with a built-in breathing valve.


The one in this picture is the oil and gas recovery valve installed on the aluminum alloy explosion-proof manhole cover.

No matter where it is installed, the functionality is the same.
