Accessories required for double layer oil tanks

Compared with single-layer tanks, double-layer oil tanks have higher safety and stability performance, and are less prone to leaks and other conditions. The operating time is longer. Which components of the double-layer oil tanks are combined? The following details the required accessories.

1.Mechanical equipment breathing valve: It is a key accessory for the manufacture of double-layer oil tanks. It is mounted on the top plate of the oil tank and is composed of a pressure valve and a vacuum valve. Its function is to ensure the tightness of the pressure vessel under most conditions and reduce the volatilization loss of the refined oil to some extent. When necessary, it can ventilate by itself, adjust the internal and external pressure of the oil tank well, and protect the oil tank.
 
2.Lighting hole: The lighting hole of the oil tank is located at the top of the tank, usually a circular hole with a diameter of 500mm. The perforated cover ring is usually fully closed with bolts. When cleaning and maintaining double layer oil tanks, it is used for lighting, ventilation and exhaust.
 
3.Fire arrester: It is a fire safety device on the oil tank. It is located under the breathing valve of the mechanical equipment on the top of the tank. If a flame enters the breathing valve, the metal wire or corrugated plate inside the flame arrester quickly absorbs the heat of the combustion gas, so that the flame is extinguished and the flame is prevented from entering the oil tank.
 
4.Accurate measurement hole: It is a special accessory used to accurately measure the level of oil in the tank and transfer oil samples. One is set on the top of each tank, most of which are located around the platform of the tank ladder. The diameter of the accurately measured hole is 150ram, and it is provided with a hole cover and an elastic bolt which can be closed. In order to avoid the fire caused by the hole cover colliding with the iron when it is closed, an oil-resistant rubber pad or soft metal is embedded in the sealing groove below the pressure vessel hole cover. 5.Manhole: The manhole of the non-metallic oil tank is located on the tank item. The manholes of metal oil tanks are located on the lower ring plate of the tank wall. Most of them are circular holes with a diameter of 600 mm. They are used for oil tank cleaning or maintenance workers to access the pressure vessel. Manholes can be used to maintain and clean double-layer oil tanks Lighting and natural ventilation.
 
The above is a detailed introduction to the accessories required for the double layer oil tank. The double layer oil tank is indispensable in the application process. The double layer oil tank is equipped with leakage detection equipment, which can realize the whole process of the gap space for 24 hours. monitor. If leakage occurs in the inner or outer tank of the pressure vessel, the sensor of the leak detection device can send an alarm when it detects the liquid level at the bottom of the gap space to ensure the safe use of the oil tank.
