Is the number 1 marked a bursting disc? ? Equivalent to a safety valve, when the pressure exceeds a certain value, the bursting disc ruptures? Does the arrow mark the normal process? ? In addition, the vent valve is a ball valve. Does it adjust the opening according to the negative pressure of the fuel tank during normal operation? What is the purpose of the ball valve marked No. 2? Is it the crossover cable for the fan? Used when the fan fails? Hope you can enlighten me! ! ! !
1 is a one-way valve used for exhaust when the fan stops and the tank pressure rises. 2 is the bypass valve. When the fan fails, open this valve. The process you marked is correct
Thanks for the guidance. . During normal operation, is the exhaust ball valve fully open or is the opening selected based on the negative pressure in the tank?
It's probably not a ball valve but a butterfly valve. This valve only needs to be fully opened, because there is a nitrogen seal on the top of the fuel tank and a flame arrester on the exhaust end.
You are right. After the fan is turned on, use this valve to adjust the negative pressure of the fuel tank to 0.2pa.
