Reverse arch blade type bursting disc is a non-re-closed safety device based on the design of the reverse arch structure and realizes overpressure relief through blade cutting. It has many advantages in the field of industrial safety protection. This article will introduce you in detail the advantages of bursting disc from several angles.
The working pressure of reverse arch blade type bursting disc can reach 90% of the calibrated burst pressure, and it can operate stably under working conditions close to the burst pressure, making effective use of the pressure space of the equipment. Compared with some rupture discs with a working pressure ratio of only 60% to 70%, the operating efficiency of the equipment is greatly improved. And reverse arch blade type bursting disc has good fatigue resistance, can be used in situations with pulsating pressure, can withstand pressure fluctuations to a certain extent, so that the rupture disc can work stably for a long period of time, suitable for compressors, reactors and other equipment with frequent pressure changes. Moreover, the bursting disc has high blasting accuracy. Within the specified temperature range, the deviation between the actual burst pressure of the rupture disc and the designed burst pressure can be controlled within ±5%, which can provide the system with more accurate overpressure protection, and timely pressure relief at accurate pressure values to protect equipment safety.
Reverse arch blade type bursting disc can withstand a full vacuum state without a back pressure bracket, which makes it more convenient for the rupture disc to be used in some systems where vacuum conditions may occur, reducing additional equipment costs and installation costs, and a wide range of application scenarios. In addition, reverse arch blade type bursting disc has a wide range of temperature applications. By choosing different materials, the bursting disc can adapt to the temperature range of -196℃ to 650℃, which can meet the requirements of various high and low temperature operating conditions.
Reverse arch blade type bursting disc adopts a monolithic metal structure and a debris-free design. It can be used in series with a safety valve to prevent debris from causing damage to subsequent equipment. It is especially suitable for precision equipment or piping systems that are sensitive to debris. During normal operation, the arch surface of the reverse arch blade type bursting disc fits closely with the gripper, and the sealing performance is good. It is suitable for toxic, flammable or clean media occasions, which can effectively prevent media leakage and ensure production safety and environmental safety. When the pressure in the equipment exceeds the set value, the reverse arch structure of the bursting disc will instantly stabilize and flip, and the diaphragm will be quickly cut by the blade, forming a complete discharge port, which can quickly discharge the medium, reduce the risk of system pressure rising, and protect the equipment from overpressure damage in a timely and effective manner.
Reverse arch blade type bursting disc can also customize the diaphragm of special materials according to the needs of special working conditions, such as stainless steel, Inkang nickel alloy, Monel alloy, nickel, aluminum, etc., to meet the requirements of different customers for special properties such as corrosion resistance and high temperature resistance. In short, bursting disc has excellent performance, can work stably under various complex operating conditions, effectively prevent the safety risks caused by equipment overpressure, and provide a guarantee for the safe and efficient operation of industrial production.
