In gas fire system design, many people only focus on cylinders and pipelines, neglecting the seemingly small but critical pressure relief opening. Actually, a gas system without relief opening is unsafe.
1. What Does Pressure Relief Opening Do?
When gas system discharges agent into enclosed protected area, large volume of gas rapidly enters, causing indoor pressure to rise quickly. If pressure exceeds structure limit, walls, windows may break. Pressure relief opening is an automatic device installed on wall, opens when pressure exceeds set value, releasing excess pressure to protect building.
2. Why It Is Essential?
- Protects building structure from overpressure damage
- Ensures personnel safety
- Guarantees fire extinguishing effectiveness
- Mandatory requirement by gas fire system design code
3. Selection Points
- Relief area calculated based on protected volume and agent concentration
- Set pressure based on structure bearing capacity
- Material: aluminum alloy for indoor, stainless steel for outdoor
- Installation position: on exterior wall near ceiling
