Material, model, emission volume, operating pressure range
The principles for selecting a safety valve are (determination of discharge volume and discharge pressure) and (determination of nozzle area).
Cheap and useful... That can’t be right, haha. I’m just checking the answer
Determination of discharge volume and exhaust pressure; Determination of nozzle area
The nominal pressure of the safety valve is determined by the operating pressure, the operating temperature range of the safety valve is determined by the operating temperature, the pressure setting range of the spring or lever is determined by the calculated set pressure of the safety valve; then, the material and structural type of the safety valve are chosen based on the working medium, and the flow channel diameter of the safety valve is calculated based on the required safety discharge volume.
