دریچه تخلیه اضطراری مخازن ذخیره از نوع فنری

Spring Loaded Emergency Vent Application GPE emergency vents are used on fixed roof storage tanks to prevent structural damage due to excess internal pressure Storage tanks are pressurized when fluid is pumped in, compressing the existing vapor or when increasing temperature causes increased evaporation or expansion of existing vapor. To prevent damage, vapor must be allowed to escape or enter the tank at a specified pressure condition. The volume rate of venting depends upon the tank size, volatility of the contents, the pumping rate and the temperature. See API Standard 2000 for the procedures to determine venting requirements
