Pressure range on the safety valve nameplate
Thread Content
The pressure range is indicated on the safety valve’s nameplate. What does the pressure range mean? Does it affect the selection of safety valves?
The pressure range varies depending on the size of the spring used in the safety valve
I don’t understand. Could you be more specific? Is the pressure range the set pressure range of the safety valve?
Safety valves have a nominal pressure and a set pressure. 1. The nominal pressure is related to the strength of the safety valve. 2. The basic opening process of a safety valve: A safety valve is primarily used to release the medium inside a container when overpressure occurs. When the pressure in the container reaches the set pressure of the safety valve, the force acting on the valve core exceeds the force of the spring, causing the safety valve to open. 3. There is a corresponding relationship between the set pressure and the spring force; each set pressure range corresponds to a specific spring, which ensures the accuracy of opening.
