Introduction of oil tanker parts

The main product accessories of the oil tanker are: manhole cover, oil and gas recovery valve, oil and gas recovery joint, subsea valve (emergency cut-off valve), oil discharge valve, anti-overflow sensor, etc. Products have the advantages of reasonable design, advanced technology, safety and reliability, energy saving and environmental protection.

1.Subsea valve

The subsea valve, also known as the emergency shut-off valve, is installed on the bottom of the tank and used when refueling. The operation is simple, time saving, safe and environmentally friendly.
Pressure-balanced subsea is used for multi-tank tanker trucks, which can carry out separate loading and unloading of different tanks. The three-way design of the intermediary pipeline reduces the load, is easy to operate, and is safe and reliable.
The pneumatic shut-off valve is installed at the bottom of the tank body of the tanker truck 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. Unable to carry excessive force, the vehicle body pipeline and the tank body will be automatically disconnected, while 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 there is no air source or it cannot be opened for other reasons, the cylinder piston rod can be opened and manually opened.


2. Oil and gas recovery valve

The oil and gas recovery valve is a device for recovering the oil and gas generated during the loading and unloading of oil. It can be directly installed on the tank of the top of the tank truck or on the manhole cover. It can be connected to the bottom of the tank through a push rod. The valve realizes mechanical linkage opening, and its opening and closing can also be controlled by the air source.
The oil and gas recovery valve can recover all the oil and gas generated by the volatilization of oil during loading and unloading to the oil tank in the reservoir area, avoiding the leakage of oil and gas, and condensing and reusing the oil and gas through other oil and gas recovery devices, thereby achieving the purpose of energy conservation and environmental protection.
Functions and features:
◆ When the tanker oil tank is filled, the oil and gas recovery valve is opened, the rising liquid level pushes the oil and gas upward, and returns to the oil tank in the reservoir area through a series of oil and gas recovery systems.
◆ When the tank truck is unloaded, the recovery valve allows the recovered gas to enter the tank truck oil tank. In systems without oil and gas recovery facilities, air is allowed to enter tanker tanks.
◆ High sealing performance ensures the safety of tank truck transportation.
◆ Reasonable valve body design to ensure high efficiency of oil and gas recovery .

3. Oil and gas recovery joint

Oil station oil and gas recovery system consists of fire blocking breathing valve, pipeline flame arrester, three-way floating ball valve, oil and gas recovery joint, oil and gas recovery quick joint, etc., and a closed loop system with the tanker oil and gas recovery system, which will effectively refuel at the gas station The oil and gas produced during the process is recycled and reused, avoiding the diffusion of oil and gas.

4.Download valve

Bottom loading valve, also known as oil discharge valve, is installed under the side of the tanker truck for fast oil discharge. The front interface is in accordance with the American API Rp1004 standard, which is convenient to connect with the discharge hose hoe. The hydrodynamic design of the internal structure minimizes internal pressure at high flow rates. The outlet adopts a flat bottom structure, and there is no oil leakage when the joint is disassembled, which is safe and reliable. The quick oil discharge hose connector adopts an inclined 70 degree design to facilitate the connection of the hose and effectively increase the service life of the hose.
Functions and features:
◆ Integral cast aluminum shell, anodized, parts can be replaced.
◆ The flat bottom structure of the outlet ensures that all the liquid is discharged and reduces environmental pollution.
◆ Two-pole fixed aluminum alloy push rod, clearly shows the valve position.
◆ Comply with American API RP1004 standard, can be docked with API connector.
◆ It adopts die-cast aluminum structure with a weight of 4.4 kg, which improves the payload.
◆ Viton seal, suitable for high octane fuel and additives.
◆ Fluidics design internal structure to minimize pressure drop at high flow.
◆ Stainless steel control shaft, spring, cam, valve stem to ensure service life.


5.Anti-overflow probe

Uses: Anti-overflow electronic sensors are widely used in all kinds of container tanks when they are hermetically filled with liquid, a safety device to prevent the liquid from leaking out in advance. It is a safety device installed on the top of the container tank. When the position reaches the warning limit, the sensor will automatically alarm and open.

6.European tank lid

It is also called manhole cover. It is installed on the top of the oil tank. It has built-in breathing and emergency exhaust functions, and can be installed on the manhole cover with oil and gas recovery valve, oil measuring hole, anti-overflow detection rod, etc. During the oil filling process, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the oil loading. The built-in breathing valve keeps the internal pressure of the oil tank stable during oil transportation and balances it with the external pressure. Its design to prevent overflow prevents the oil tanker truck from being sealed in the event of an accident. The pressure of the emergency exhaust device inside the tank In the case of a sharp rise, it will automatically open to release the pressure in the tank, thereby preventing accidents and greatly improving the safety of oil transportation.
Functions and features:
◆ Different pressure parameters can be set as required to ensure reliable breathing function and emergency exhaust function.
◆ Breathing function When the internal pressure of the oil tank is higher than the external pressure by 6 ~ 8KPa or lower than the external pressure by 2 ~ 3KPa, the breathing valve will automatically open to allow the gas inside and outside the tank to penetrate, which can reduce the excessive pressure difference between the inside and outside, and provide safety protection effect. When the pressure difference between the internal pressure of the oil tank and the external pressure is -2 ~ 6KPa, the breathing valve is closed to keep the proper pressure in the tank, so as to avoid the volatilization of the oil.
◆ Overflow prevention in the event of an accident and dumping of the tanker, the anti-overflow stopper in the breathing valve automatically seals the channel to prevent danger due to oil leakage.
◆ Emergency ventilation When the tanker is accidentally in a high temperature environment, it can effectively release the pressure in the tank and prevent the tank from exploding. When the internal pressure of the tank exceeds the external pressure of 21 ~ 32KPa, the emergency exhaust device starts to work, and its maximum exhaust volume reaches 7000m3 / h, which can effectively prevent the explosion accident of the oil tank.
◆ Two-stage opening: After the tank lid is fully opened, release the pressure inside the tank first.
◆ Can be equipped with a lock and configured according to user requirements.
◆ Three auxiliary openings can be used to install oil measuring holes, anti-overflow detection rods, and oil and gas recovery valves.
