In industrial production, pressure vessels often face the risk of overpressure during operation. Once the overpressure is not discharged in time, it may lead to equipment damage, media leakage and other problems. Therefore, in order to allow the pressure vessel to operate safely, bursting disc has become an important pressure relief safety device, which plays an important role in preventing overpressure.
The bursting disc device is mainly assembled from components such as bursting disc and gripper. It has the characteristics of simple structure and rapid response. It can quickly release pressure under extreme conditions and prevent equipment damage and casualties. When the pressure difference between the two sides reaches a preset value under specific temperature conditions, the bursting disc will respond quickly, and then release the pressure medium by breaking or falling off to prevent the pressure vessel, pipeline, or enclosed space from being damaged due to overvoltage.
Bursting disc is usually divided into two types, namely positive arch type bursting disc and anti-arch type bursting disc. The positive arch type bursting disc is also known as the stretched metal bursting disc. It is characterized by the arched projection of the pressure-sensitive element. During the installation process, the concave side of the arch surface faces the high-pressure area of the system, and during the operation, the bursting disc will break due to stretching. Anti-arch type bursting disc is also known as compressed metal bursting disc. The pressure sensitive element exhibits a reverse arch. When installed, the convex side of the arch faces the high-pressure side of the pressure system. During the operation, the bursting disc will break or fall off due to unstable compression.
Nouns related to bursting disc:
1. Back pressure refers to the static pressure present on the discharge side of the bursting disc device. This pressure may be caused by other pressure sources on the discharge side, or it may be formed due to a vacuum state on the inlet side.
2. Broken sheet refers to the sheet metal before it is processed into an arch structure, usually stamped or cut from a thin metal strip or sheet metal.
3. The burst pressure is the pressure difference between the two sides when the bursting disc device is activated under the specified burst temperature conditions.
4. The design burst pressure is the burst pressure value that should be reached at a specific burst temperature specified by the demand side during the process of bursting disc design.
5. The test burst pressure refers to the actual burst pressure measured by the bursting disc at the moment of blasting during the blasting test, and the test burst temperature should be measured at the same time.
6. The burst temperature is the temperature of the wall of the pressure sensitive element corresponding to the burst pressure.
7. The manufacturing range is to facilitate the manufacture of bursting disc, and the pressure range that the burst pressure is allowed to change during manufacturing is designed.
8. The discharge area is the geometric flow channel area in the bursting disc device. This area is the basic parameter used to determine the theoretical discharge amount of the bursting disc device.
9. The discharge volume is the total flow rate of the pressure medium that can be discharged through the discharge area after the bursting disc is exploded.
