The important role of accessories in oil tanks

Oil tank is a very complex product. It has many components, and many of them also play a very important role. I believe everyone is very clear in the process of using it. So what is the ground oil tank? Which components play a vital role.
 
1, Manhole. It is used for the access and ventilation of the repairing fuel storage tank. The diameter is about 700mm. The manhole cover is usually equipped with oil measuring holes, vent pipes and oil inlet and outlet pipelines. There is no manhole above the manhole for operation and protection.
 
2, oil measuring hole. Used for measurement, sampling and observation. An oil measuring tank made of aluminum alloy is provided to avoid sparks when the ruler is lowered. A sealing groove is set under the hole cover and an oil-resistant rubber gasket is embedded to seal and prevent cremation due to collision when the hole cover is closed. Some oil measuring holes are in the form of steel pipe sleeve copper caps (caps), which are mainly sealed by the weight of the copper cap and gaskets.

3. Ventilation hole (breathing tube). It is used for the oil vapour in the unloading tank to be discharged out of the tank and to inhale air when filling the oil. 4, Choke cap. It is the supporting equipment of the oil tank of the gas station, installed on the top of the oil tank vent. When the oil tank transports oil products, the corrugated plate sucks in air and does not let the fire source pass through.　

5. Connector. The automobile adopts a closed oil unloading method, and the oil unloading pipe is connected with the oil inlet of the oil using a sealed joint. The oil is unloaded from the oil tanker into the fuel storage tank through the oil unloading pipe joint. This joint is easy to operate, quick to assemble and disassemble, can reduce oil and gas, and reduce air pollution.
 
6. Emergency shut-off valve. It is a valve used with a submersible pump and is installed on the bottom pipeline of the gas station.
