The role of the European standard for tank trucks:
Oil and gas recovery: Oil and gas recovery valve The oil and gas recovery valve is a device that recovers the oil and gas generated during the loading and unloading of oil. It can be installed directly on the top tank of the tanker or on the manhole cover. It can be pushed through a pusher. The bottom valve of the rod and the bottom of the tank can be opened mechanically, and can also be controlled by the air source to open and close.
Oil and gas recovery joints: The oil and gas recovery system of the oil station is composed of fire-resisting breathing valve, pipeline flame arrestor, three-way floating ball valve, oil and gas recovery joint, and oil and gas recovery quick joint. It forms a closed circulatory system with tanker oil and gas recovery system. The recovery of oil and gas generated during the refueling process at the petrol station avoids the proliferation of oil and gas.
Subsea valve subsea valve: Subsea valve Subsea valve, also called emergency shut-off valve, is installed at the bottom of the tank and is used for down loading and refueling. It is easy to operate, saves time, and is safe and environmentally friendly. Pressure balanced subsea valves are used for multi-tank tank trucks, which allow separate loading and unloading of different tanks. The three-way design simplifies the piping, reduces the load, and is simple to operate, safe and reliable.
Bottom-mounted valves Bottom-mounted valves, also known as unloading valves, are mounted under the side of the tanker for quick unloading.
Anti-overflow probe use: Anti-overflow electronic sensor is widely used in a variety of container tanks in the closed liquid filling, in order to prevent the overflow of the liquid to prevent early leakage of a safety device, it is installed in the tank top of the manhole Cover, when the oil level reaches the warning limit, the sensor will automatically alarm to break the brake.
The European standard canopy is also called the manhole cover. It is installed on the top of the oil tank and has built-in breathing and emergency exhaust functions. It can also install oil and gas recovery valves, oil holes, anti-overflow probes, etc. on manhole covers. Anti-overflow sensing system In the oil loading process, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the loading of oil. The built-in breathing valve keeps the internal pressure of the tanker tank stable during the oil transportation and balances with the external pressure. The design of the dumping overflow prevention prevents the tanker from being sealed in the event of an accident. The emergency exhaust device is When the pressure in the tank rises sharply, it will be automatically opened to release the pressure inside the tank, thereby preventing accidents and greatly improving the safety of oil transport.
