扭转半球形的刀刃盘破裂

Pressure acts on the convex side of rupture disk. At its burst pressure, the disk reverses with the knife blades on the upper holder cutting it . Types Reverse Domed With Knife Blades Rupture Disk (YD): The disk is made up of sphere solid metal with burst pressures ranging from 0.05MPa to 12.0MPa.Reverse Domed Rupture Disk With Knife Blades (YDV): The disk consists of brackets and corrosion-resistant seal membrane with burst pressure ranging from 0.001MPa to 0.1Mpa, and suitable for super-low or vacuum vessels.Features Optimum fatigue resistance for pressure pulsating or cycling conditionMaximum operating pressure up to 90% of the minimum burst pressure Withstand full vacuum condition without vacuum support (YD type)Non-fragmenting design, suitable for safety valve isolation.Designed for gas, dust service, and not suitable for no gas space equipmentNot suitable for high burst pressure conditions
