European tanker fittings six sets of detailed instructions 1. European standard manhole Uses: The manhole cover is installed on top of tanker tank, with internal breathing and emergency exhaust function. The internal breathing valve keeps the internal pressure of the tanker in balance with the external pressure during the oil transfer process. The emergency exhaust device will automatically trip open and release internal pressure when the pressure in the tank rises sharply. Even in the event of an accident in the tank, the overflow valve of the inner breathing valve remains sealed and the medium in the tank does not penetrate to prevent major accidents. The manhole cover can be fitted with an exhaust gas recovery valve, a metering hole, an overflow probe rod, and the like. 2. Pneumatic bottom valve Uses: Installed in the bottom of the tank, automatic disconnection in case of emergency to prevent leakage. Automatic alignment plungers and durable springs maintain the original tightness after an emergency shut-off of the valve body. Emergency measures When no air supply or special reasons can not be opened normally, it can be opened manually without disassembly. 3, oil and gas recovery valve Purpose: 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 it can be installed on the manhole cover. It can pass a push rod and the bottom of the tank. The sea-bottom valve realizes mechanical linkage opening, and it can also be controlled by the air source to open and close it. The oil and gas recovery valve can recover all the oil and gas produced by the oil evaporation during loading and unloading into the oil tank in the reservoir area, avoid oil and gas leakage, and condense and reuse oil and gas through other oil and gas recovery devices, thus achieving the purpose of energy conservation and environmental protection. 4, oil and gas recovery joints Oil and gas recovery joints Oil and gas recovery reducer Aluminum dust cover Purpose: The oil gas recovery joint is installed near the oil discharge valve or parking space under the vehicle body. It adopts a quick connection method, which is convenient for loading and unloading. The valve stem opens into the oil tank to prevent the tanker from tipping over due to high pressure. Installed on the oil and gas recovery system, it can control the opening and closing of oil and gas recovery valves. It is an important part of oil and gas recovery for tankers and external devices. 5, unloading valve Oil unloading valve Oil unloading valve reducer Oil unloading valve plastic dust cover Purpose: The API unloading valve is installed under the side of the tanker for quick unloading. The front-end interface complies with U.S. API Rp1004, which is convenient for connecting with the unloading hose. Hydrodynamics designed the internal structure to minimize internal pressures 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-discharge hose connector is designed with an angle of 70 degrees to facilitate the connection of the hose and effectively increase the service life of the hose. 6, anti-overflow probe, socket Uses: Anti-flooding electronic sensors are widely used in a variety of container tanks in the closed liquid filling, in order to prevent the overflow of the liquid spill warning and a safety device, it is installed in the top of the container tank cover, when the oil When the alarm limit is reached, the sensor will alarm automatically.
