A pressure relief device which consists of a part of a blasting piece (or a component of a bursting piece) and a clamping unit (or a support ring). At the set blasting temperature, when the pressure difference between two sides of the blasting piece reaches the preset setting value, the blasting piece immediately moves (breaks or falls off), and releases the releasing body medium.
The blasting piece can be blasted under the specified temperature and pressure, releasing pressure.
The blasting device is composed of a blasting piece and a clamping apparatus. The blasting plate is a component which is in the condition of the blasting pressure and the temperature, and the clamping device is the auxiliary element for holding the blasting piece in the appropriate part of the container.
The safety device of the blasting piece has the advantages of simple structure, sensitive, accurate, no leakage, strong discharging ability and so on. Able to work reliably in a viscous, high-temperature, low temperature, corrosive environment, or an ideal safety device for ultra-high pressure vessels.
The blasting piece is an important safety device to prevent overpressure damage of pressure equipment, and is widely used in chemical industry, petroleum, light industry, metallurgy, nuclear power, dedusting, fire fighting, aviation and other industrial sectors.
