RKG series manhole cover is installed on the top of oil tanker and used for loading oil ,checking gas recovery,mending the internal inlet.
Also can protect the tanker under the emergency. When loading oil,the outside temperature’s change will lead the tanker’s inside pressure to change. Then the manhole cover’s breathing valve can automatically make the tanker pressure to the normal level. If some emergency happen , like the tanker overturn,the breathing valve will automatically close to avoid the tanker’s explosion when under the fire condition..
