How are the triggering conditions for overpressure protection devices and leak detection sensors determined?

As a key device for controlling the flow of CO2, the safety of the manual carbon dioxide valve is directly related to the stable operation of the entire system and the safety of personnel. To this end, the valve puts the safety protection mechanism at the core position at the beginning of its design, and builds an indestructible safety line by integrating advanced overpressure protection devices and leak detection sensors.

Overpressure protection: accurate prediction, preventive measures
The overpressure protection device is the "guardian" of the valve safety system. It uses a high-precision pressure sensor as a core component, which can monitor the pressure changes inside the valve and the pipeline system in real time. So, how is the trigger condition of this device determined?
The key lies in the precise definition of the normal working pressure range of the system. Designers will first calculate the maximum allowable working pressure of the system based on factors such as the use scenario of the valve, the characteristics of the medium and the material of the pipeline. Subsequently, through a large number of experiments and data analysis, a "safety threshold" slightly higher than the maximum value is determined as the trigger point of the overpressure protection device. When the system pressure exceeds this threshold due to a fault, operating error or other reasons, the overpressure protection device will respond immediately, automatically close the valve or trigger an alarm signal, thereby effectively preventing equipment damage or safety accidents caused by overpressure.

Complementing the overpressure protection device is a high-precision leak detection sensor. This sensor is like a sharp "detective" that can accurately capture tiny signs of gas leakage, ensuring that any potential leakage risks can be discovered and handled in a timely manner.

The triggering conditions of the leak detection sensor are also based on rigorous scientific calculations and experimental verification. First, the designers will analyze the physical and chemical properties of CO2 and its flow characteristics in the pipeline to determine a reasonable leak detection sensitivity range. This range must be able to accurately capture tiny leaks while avoiding false alarms caused by excessive sensitivity. Subsequently, by simulating leakage conditions under different working conditions, the sensor is repeatedly tested and calibrated to ensure that it can work stably and reliably in actual applications.

The technical innovations of this manual CO2 valve in overpressure protection and leak detection do not exist in isolation. They are closely linked to the overall design of the valve, material selection, manufacturing process and other aspects, and together constitute an efficient, safe and reliable CO2 control system.

For example, in the selection of valve materials, high-strength, corrosion-resistant special alloys are used to ensure that good sealing performance and mechanical strength can be maintained under high pressure, low temperature or corrosive environments. In terms of manufacturing technology, advanced precision processing and testing technologies are introduced to ensure that every component can meet the design requirements, thereby improving the performance and life of the entire valve.
