How much pressure or pressure does the breather valve or safety valve on the tank train take off?
According to the national standard 18564, the tanker is an atmospheric pressure vessel, the vent valve of the breather valve is opened when the pressure in the tank is higher than the outside pressure 6~8KPa, and the intake valve shall be opened when the pressure in the tank is less than 2~3KPa of the outside pressure.
The breather valve or safety valve on the tanker will not take off if it is working. It is not normal to have pressure in the tank. Check that the relief valve is normal.
But it is still a little bit, what is called the breathing valve, that is, the gas into the air, it can breathe, can it be a value, huh?.
People ask is the opening pressure of the respiratory valve, there is pressure, how abnormal, halo is very.
