Spring-loaded safety valves are mostly used in pipeline systems, petrochemical companies, and other places where there is a large temperature difference. The spring type safety valve has the characteristics of good stability and high strength. In the pipeline system, the main function of the spring type safety valve is to stabilize the internal pressure in the pipeline system so that no excessive pressure difference is generated in the system. Another characteristic of the safety valve is that it has enough toughness, which also ensures that it can maintain a good effect under a certain temperature difference. It is understood that this "Specification" was independently carried out in the Leshan City Special Inspection Institute and obtained 2016 The Leshan City Science and Technology Progress Second Prize “Research on the Application of Safety Valve Online Calibration†based on the municipal scientific research projects, another important achievement has been the first local technical standard of the Leshan City Special Inspection Institute as the main drafter.
This standard mainly focuses on the current status of safety valve online calibration errors and inaccurate calibration pressure check values. It also points out the improvement direction of safety valve online calibration and provides technical basis and guarantee for on-line verification of safety valve in the province. Has strong practicality and operability.
