Technical Field
The safety valve is a special valve, wherein the opening and closing part is in a normally closed state under the action of external force, and when the pressure of a medium in equipment or a pipeline rises to exceed a specified value, the medium is discharged to the outside of the system to prevent the pressure of the medium in the pipeline or the equipment from exceeding the specified value.
An important parameter in a safety valve is a set pressure, and the setting of the set pressure is directly related to the safety of equipment operation. Further, the set pressure is a predetermined pressure at which the safety valve flap starts to open under operating conditions, and is a gauge pressure measured at the valve inlet. At this pressure, the force generated by the pressure of the medium, which opens the valve, and the force with which the flap is held against the valve balance each other under the specified operating conditions.
In the existing safety valve setting pressure calibration, the setting pressure can be determined only by manually and repeatedly tightening and loosening a safety valve spring and performing a plurality of times of tripping safety valve tests. Thus, the working efficiency is severely limited.
