In industrial production, the safety of equipment in a high-pressure environment is very important. When the pressure in the equipment rises abnormally and exceeds the normal working pressure range, it is very easy to cause serious accidents such as equipment damage or even explosion, which not only threatens the life and safety of personnel, but also causes huge economic losses and environmental pollution. As an important device for the safety protection of high-voltage equipment, rupture disc can effectively cope with the challenges of high-voltage environments and plays an important role in many industries.
The rupture disc consists of an arched metal diaphragm and a gripper with a blade. During normal operation, the convex surface of the rupture disc undergoes pressure toward the medium side, taking advantage of the mechanical advantages of the arched structure to disperse the pressure and maintain stability. When the pressure in the equipment reaches the preset burst pressure, the anti-arch structure instantly stabilizes and flips. The concave surface is in contact with the blade on the gripper. The blade quickly cuts the diaphragm, forming a discharge channel, and the overpressure medium is discharged in time to reduce the pressure in the equipment and prevent accidents. This design gives rupture disc many advantages, such as a working pressure ratio of up to 90%, which can operate stably under conditions close to burst pressure. The blade is accurately cut to achieve debris-free blasting, preventing debris from clogging pipelines or damaging downstream equipment. Rupture disc has excellent sealing performance and can be used in high-pressure media scenarios that are toxic, flammable, or require a clean environment. In addition, rupture disc also has good fatigue resistance, can adapt to frequent fluctuations in pressure, withstand a wide temperature range, and can cope with corrosive, viscous or high-pressure media containing small particles through reasonable material selection.
In the electric power industry, thermal power generation boilers, steam turbines, and nuclear reactor cooling systems of nuclear power plants are all high-pressure equipment. The steam pressure of the boiler can reach 10 to 30Mpa when it is running. Once the pressure is out of control, it may cause a steam explosion. In this scene, the rupture disc is installed in an important part to quickly relieve pressure when the pressure rises abnormally. In nuclear power plants, the pressure of the cooling system of the nuclear reactor is high and the medium is radioactive, and the requirements for safety devices are very strict. The high-precision burst pressure control and reliable sealing of rupture disc allow the rupture disc to safely release pressure under extreme operating conditions, prevent the leakage of radioactive materials, and protect the safety of nuclear facilities.
In the pharmaceutical industry, high-pressure reactors are used to synthesize active pharmaceutical ingredients, usually at a pressure of 5 to 15 MPa. The process of drug synthesis requires high environmental cleanliness, and some reaction media are corrosive and toxic. Rupture disc is made of corrosion-resistant materials, which can not only resist the corrosion of the medium, but also ensure that no debris is generated, and prevent pollution to the quality of medicines. At the same time, the precise burst pressure control of the rupture disc under high pressure ensures the safety and stability of the reaction process and complies with the strict production specifications of the pharmaceutical industry.
