Description

Technical Field

[0001] This utility model relates to the technical field of pressure vessel safety control devices, specifically a safety control device for pressure vessels. Background Technology

[0002] The pressure vessel safety control device converts the pressure signal into an electrical signal using a pressure sensor when the pressure inside the pressure vessel exceeds or falls below a set safety value. This signal is then transmitted to the alarm controller, which triggers an audible and visual alarm to alert operators to take appropriate measures. The device responds quickly, issuing an alarm at the first sign of pressure abnormality. Multiple alarm thresholds can be set to provide different levels of alarm alerts. However, regular calibration and maintenance are required to ensure its reliability.

[0003] Existing pressure vessel safety control devices are susceptible to interference from environmental factors such as high temperature, humidity, and vibration, which can lead to inaccurate measurements and false alarms. If a pressure vessel safety control device malfunctions, it needs to be repaired promptly; otherwise, the pressure vessel may not be able to function properly. Utility Model Content
