Can a burst disc withstand negative pressure in the equipment, and activate to protect the equipment once a certain level of negative pressure is reached?
There are relevant explanations for this; it functions in a similar way to a safety valve. The parameters suitable for what level of negative pressure should be based on the instructions.
Is it to prevent negative pressure in the equipment? Similar to breaking a vacuum
I don’t know what type you need. If it is of the negative pressure type, should the issue of how to handle the rupture disc entering the device be considered? If it is used in positive-pressure equipment, whether it will break under negative pressure depends on the value of the positive pressure. The greater the positive pressure blasting value, the greater the negative pressure resistance value as well. It is best to provide specific examples for reference.
Sure, find a rupture disc manufacturer to select one.
When the rupture disc is installed correctly, it will burst if the internal pressure exceeds a certain level; when installed inversely, it will also burst if the external pressure exceeds that level. Solving this problem requires design and evaluation. A rupture disc is just that – a rupture disc. The manufacturer is to be chosen based on the desired pressure level, and the manufacturer is not responsible for any issues other than those related to the rupture disc itself; the design party is responsible for such issues
However, considering the structure and strength of the rupture disc itself, there is indeed a problem of the rupture disc being subjected to negative pressure during the vacuuming process of the equipment
