How to choose between safety bursting disc and safety valve in practical application?
When choosing to use safety bursting disc or safety valve, it is necessary to decide based on the specific application conditions, media characteristics, pressure range and safety requirements. In practical applications, sometimes both are used at the same time to provide more comprehensive safety protection. Here are some key considerations:
1. Type of overpressure protection:
If you need to prevent occasional or extreme overpressure conditions, safety bursting discs may be a better choice because they can respond quickly when overpressure occurs.
If the system needs to adjust the pressure frequently or there is a continuous risk of overpressure, safety valves may be more suitable because they can automatically open and close when the pressure exceeds the set value.
2. Characteristics of the medium:
For corrosive, viscous or solid particles containing media, safety bursting discs may be a more suitable choice because they are simple in design and are not easily affected by the characteristics of the media.
Safety valves are suitable for a variety of media, but special materials or designs may be required for special media to prevent clogging or corrosion.
3. System requirements:
Considering the size, pressure range, temperature and other operating conditions of the system, choose a safety device that can meet these requirements.
Considering the maintenance and inspection procedures of the system, select devices that are easy to maintain and calibrate.
4. Economy:
Consider the initial cost, operating cost and maintenance cost of the equipment, and select an economical and reasonable solution.
A safety bursting disc may have a lower initial cost, but it needs to be replaced regularly; a safety valve may have a higher initial cost, but it can be used for a longer time with proper maintenance.
5. Safety and reliability:
Choose a reliable safety device based on the safety requirements and operating environment of the system. Considering the failure mode and potential safety risks of the device, select a device that can provide the necessary protection at critical moments.
In actual applications, safety bursting discs and safety valves are installed on key equipment at the same time to ensure rapid pressure relief in extreme cases, while safety valves are relied on to regulate pressure in daily operations. In short, the choice of bursting discs or safety valves requires comprehensive consideration of factors such as the type of overpressure protection, the characteristics of the medium, the requirements of the system, economy, regulatory standards, and safety and reliability. By comprehensively evaluating these factors, a safety device suitable for a specific application can be selected.
