Anti-arch slit type Rupture Disk with A Medium or Low Pressure
By the arch surface with a plurality of serrated and rod pieces of metal film and sealing film combination. In use, the convex surface contacts the media with the concave side toward the bleed side, and the rupture disk receives a uniform compressive load. When the system overpressure, rod instability caused after the arch completely reversed in an instant, the seal film is cut during the reverse sawtooth, relief pressure, which play a protective system security role.
Advavtage
1.Simple structure, high sensitmty, accuracy, zero leak, strong discharging capability, and strong capability of recycling under pressure
2.It maintains high operation precision even in sticky, high-temperature,low-temperature, and corrosive environments in combination with a safety valve.
3.It is an ideal safety device for ultra-high pressure vessels, widely used in the omchemical, pharmaceutical, new energy, and low-temperature equipment industries.
4.It can be classified into three catagories: domed bursting discs, reverse domed bursting discs and flat bursting discs.
Features
· Broad range of application, and can choose the corresponding assembly according to different burst pressure and vent area.
· Manufacturing ranges depend much on material strength.
· Designed for gas, liquid service
· Suitable for high temperature and pressure conditions.
· Maximum operating pressure equal to or less than 70% of the minimum burst pressure, and not suitable for pressure pulsating conditions.
· Fragments on burst.
· Short service life and easily cause creep deformation and fatigue damage
· Obvious temperature effect may cause burst pressure fluctuation. The temperature goes up while burst pressure declines.
Property
1 )The maximum operating pressure is up to 80% of the bursting pressure; the product is not applicable to environments with fluctuating pressure, which leads to metal fatigue;
2)The product leaves a small amount of debris after bursting, and can not be used in tandem with a safety valve.
When TEF or a similar material is used for sealing, the working temperature of the product may be restricted by that of the seal membrane material.
3)Based on the specific process needs of a system, auxiliary devices such as a vacuum bracket or a stiffening ring can be added to obtain LPZ, LPH, or LPHZ models.
Application
Gaseous, liquid, or powdery environments with a medium or low pressure.
