What are the types of safety devices for pressure vessels?

1. Pressure relief device
Safety valve:
Function: When the pressure in the container exceeds the set value, the safety valve automatically opens to discharge a certain amount of medium, so that the pressure in the container drops, preventing the container from exploding due to overpressure.
Features: Simple structure, high reliability, and reusable. The opening pressure can be adjusted according to different pressure requirements.
Burst disc:
Function: When the pressure in the container reaches the designed bursting pressure of the burst disc, the burst disc ruptures instantly, quickly releases the pressure in the container, and protects the safety of the container.
Features: Rapid response and good sealing. Once the bursting disc is replaced, a new burst disc needs to be replaced.
2. Measuring display device
Pressure gauge:
Function: Real-time display of the pressure value in the container, so that the operator can understand the pressure condition in the container and take corresponding measures.
Features: Various types, including ordinary pressure gauges, seismic pressure gauges, etc., can be selected according to different use environments.
Thermometer:
Function: Measure the temperature of the medium in the container to prevent the safe operation of the container from being affected by excessively high or low temperatures.
Features: There are contact and non-contact thermometers, which can accurately reflect the temperature changes in the container.
3. Alarm device
Pressure alarm:
Function: When the pressure in the container reaches the set alarm pressure value, an audible and visual alarm signal is issued to remind the operator to pay attention to the abnormal pressure of the container.
Features: Abnormal pressure can be detected in time to avoid accidents.
Temperature alarm:
Function: When the temperature of the medium in the container exceeds the set alarm temperature value, an alarm signal is issued to prompt the operator to take measures.
Features: High sensitivity and can respond quickly to temperature changes.
4. Interlocking device
Quick door interlocking device:
Function: Used for quick-opening door pressure vessels to ensure that the door cannot be opened when there is pressure in the container; when the door is not closed in place, the container cannot be pressurized.
Features: Improve the safety of quick-opening door pressure vessels and prevent misoperation.
Safety interlocking system:
Function: Interlock the various safety devices and operating parameters of the pressure vessel. When a parameter is abnormal, automatically take corresponding safety measures, such as stopping feeding, starting the pressure relief device, etc.
Features: Strong comprehensiveness, can achieve all-round safety protection.
