The tank body is elliptic cylindrical, round or trapezoidal cylindrical, etc., made of high quality steel plate,
The entire tank can be single-chamber or multi-compartment division, There are steel division plates with through holes welded in the tank to strengthen the anti-wave and relieve oil shocks. To prevent corrosion, the outer tank painted rust and decorative paint.
Tank Manhole Assembly
The manhole is placed on the top of the tank, the material is aluminum or stainless steel, with the functions of breathing and emergency venting. Gas recovery valve, fuel gauge and anti overflow probe can be mounted on the manhole cover. The built-in breathing valve can keep the internal and outside pressure balance in the process of transportation, and keep sealed at the time of the accident. The emergency venting device will automatically open to release the pressure in the tank in case of accidents and greatly improve the security of oil transportation.

2.4. Tanker Sea Valve (emergency shut-off valve)
Sea valve is mounted on the bottom of the tank, has the options of pneumatic manual, aluminum or stainless steel material, Generally pneumatic valve is first chosen. The valve has small internal pressure, flow amount. There are cut-grooves in the flange. When accident occurred, as the cut-groove can’t bear too much momentum, the pipe and tank body will be disconnected automatically. The tank medium can be leak. That makes sure the safety of the tank.
To ensure the valve has a good ability to work, what conditions must be met:
A, When the sea valve works, the system must ensure the air pressure >0.4 MPa.
B, The valve body and plunger must keep a high degree of sealing.
C, The spring must have enough elastic force to reset.
The PTO is mounted on the transmission, there are two types of left and right, the main function is to shift the power of the engine to the pump by drive shaft. For the operation function, please check the PTO instruction manual.
There are self-suction centrifugal pump and gear pump. For the performance, please check the instructions.
Hose connectors use CRJ65 type quick connector, direct butt joint, connector face with a rubber ring seal, easy dismounting and connecting, convenient and reliable. Oil hose assembly is past the conduct inspection, safe and reliable.
2.8. Ball valve
The tanker output valve adopts ball valve structure. Valve includes seat, seal ring, ball and handle. Turning 90 degree can close or open the valve. The tightness of the ball valve can be adjusted.
2.9. Four-way ball valve
The control valve is used for the four-way valve. The red dot on the stem indicates that direction is turned off.
2.10. Antistatic device
(1) Ground wire or tap (Anti-static belt)
The ground tape is mounted on the rear of the oil tank and kept in contact with the ground. Its function is transmit the static electricity to the ground which is generated from oil shocks or refueling truck works or tanker truck self engine works, to prevent fires caused by static electricity.
(2) Ground pole (Anti-static pole )
The ground pole is fixed to the frame. When refueling or discharging the oil tank truck, make sure to insert the ground pole in the damp earth to transmit the static electricity to the ground, which generated at the process of refueling and discharging.
