The main product accessories of bottom-loaded oil tank trucks include manhole covers, oil and gas recovery valves, oil and gas recovery joints, subsea valves (emergency shut-off valves), unloading valves, anti-overflow sensors, etc. The products have the advantages of reasonable design, advanced technology, safety and reliability, energy saving and environmental protection.
Subsea valve
Subsea valve, also known as emergency shut-off valve, is installed at the bottom of the tank and is used when loading and refueling. It is easy to operate, saves time, is safe and environmentally friendly.
The pressure-balanced subsea tank truck is used for multi-silo oil tankers and can carry out separate loading and unloading of different oil tanks. The tee is designed with separated pipelines to reduce the load, is simple to operate, safe and reliable.
The pneumatic cut-off valve is installed at the bottom of the tanker body and can be loaded and refueled. The internal pressure of the valve is small and the flow rate is large. There is a cutting groove on the flange side of the valve body. When an accident occurs in the oil tank, Since the broken groove cannot bear excessive momentum, the vehicle body pipeline and the tank body will automatically disconnect, while the automatic centering plunger and durable spring will still maintain a seal, and the medium in the tank will not leak, thereby ensuring the safety of the oil tank. When there is no air source or cannot be opened for other reasons, the cylinder piston rod can be folded and opened manually.

Oil and gas recovery valve
The oil and gas recovery valve is a device that recovers the oil and gas generated when loading and unloading oil. It can be installed directly on the top of the tank truck or on the top of the tank truck. The manhole cover can be opened mechanically through a push rod and the seabed valve at the bottom of the tank, or its opening and closing can 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 into the oil tank in the storage 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 tank is filled, the oil and gas recovery valve opens, and 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 tanker is unloading oil, the recovery valve allows the recovered gas to enter the tanker tank. In systems without vapor recovery facilities, air is allowed to enter the tanker tank.
◆ High sealing performance ensures the safety of tank truck transportation.
◆ Reasonable valve body design ensures high efficiency of oil and gas recovery.
Oil and gas recovery joint
The oil and gas recovery system of the oil station is composed of a fire retardant breathing valve, a pipeline flame arrester, a three-way float valve, an oil and gas recovery joint, an oil and gas recovery quick connector, etc., and forms a closed circulation system with the tanker oil and gas recovery system. Effectively recycle and reuse the oil and gas generated during the refueling process at the gas station to avoid the spread of oil and gas.
Bottom loading valve
The bottom loading valve, also known as the oil unloading valve, is installed under the side of the tank truck and is used to quickly unload oil. The front end interface complies with American standards and is convenient for connecting with the oil discharge hose. The internal structure of the fluid mechanics design can reduce the internal pressure to a minimum when the flow is large. The outlet adopts a flat bottom structure, and there is no oil leakage when the joint is disassembled, making it safe and reliable. The quick oil discharge hose joint adopts a slope design to facilitate hose connection and effectively extend the service life of the hose.
Functions and features
◆ Integral cast aluminum casing, anodized, parts replaceable.
◆ The flat bottom structure of the outlet ensures that all liquid is discharged and reduces environmental pollution.
◆ Two-pole fixed aluminum alloy push rod clearly shows the position of the valve.
◆ Complies with American standards and can be connected with connectors.
◆ Using die-cast aluminum structure, the weight is 50kg, which increases the payload.
◆ Viton seal, suitable for high-octane fuel and additives.
◆ Fluidically designed internal structure minimizes pressure drop at large flow rates.
◆ Stainless steel control shaft spring cam valve stem ensures service life.
Anti-overflow probe
Purpose The anti-overflow electronic sensor is widely used in various types of containers and cans when they are filled with liquid in a sealed manner. It is a safety device that provides an early alarm to prevent the liquid from overflowing and leaking. It is installed On the top manhole cover of the container tank, when the oil level reaches the warning limit, the sensor will automatically alarm and shut off the gate.

European standard tank cover
Also known as manhole cover, it is installed on the top of the oil tank. It has built-in breathing and emergency exhaust functions, and an oil vapor recovery valve can be installed on the manhole cover. During the oil filling process, the anti-overflow sensing system will automatically alarm when the liquid level reaches the detection position, thereby stopping the oil filling. The built-in breathing valve keeps the internal pressure of the tank stable and balanced with the external pressure during the oil transportation process. Its tilting design to prevent overflow keeps the tanker sealed in the event of an accident. The emergency exhaust device reduces the pressure inside the tank. In the event of a sharp increase, it will automatically open and 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 according to needs to ensure reliable breathing function and emergency exhaust function.
◆ Breathing function: When the pressure inside the tank is higher than the external pressure~or lower than the external pressure~, the breathing valve will automatically open to allow the gas inside and outside the tank to pass through, which can reduce the excessive pressure difference between the inside and outside and provide safety protection. effect. When the difference between the internal pressure of the oil tank and the external pressure is ~, the breathing valve is in a closed state to maintain appropriate pressure in the tank to avoid volatilization and waste of oil.
◆ Anti-overflow and anti-overflow When an unexpected situation occurs and the tanker truck overturns, the anti-overflow stopper in the breathing valve automatically seals the channel to prevent danger due to oil leakage.
◆ Emergency ventilation: When an oil tank truck is exposed to a high temperature environment in an accident, it can effectively release the pressure inside the tank and prevent the oil tank from exploding. When the pressure inside the tank exceeds the external pressure ~, the emergency exhaust device starts working, and its maximum exhaust volume reaches /, which can effectively prevent the explosion accident of the oil tank.
◆ In two-stage opening, after the tank lid is fully opened, the pressure inside the tank is released first.
◆ Can be locked and configured according to user requirements.
◆ Three auxiliary openings can be used to install oil measuring holes, anti-overflow probe rods, and oil and gas recovery valves.
