The working principle of this safety protection device is based on the balance between positive pressure and negative pressure.
The working principle of the flame retardant breathing valve mainly relies on the spring limiting valve plate, which is determined by the positive and negative pressure to exhale or inhale. Specifically, when the container is under positive pressure, the flame-retardant breathing valve opens to release the exhaled gas to release the positive pressure; when the container is under negative pressure, the flame-retardant breathing valve opens to inhale the gas to release the gas; negative pressure. This can ensure that the pressure is within a certain range and ensure the safety of the container.
Can be used together.
First of all, the breathing valve can actually be considered a type of safety valve. Breathing valvesres are often used in conjunction with flame arresters. Fire breathing valves are very common.
It is rare for safety valves to be used directly with flame arresters, but there is plenty of precedent. We have often offered a combination of safety valves and flame arresters. It all depends on the design of the process.
It works both theoretically and practically.
