Description

Technical Field

[0001] The utility model relates to the technical field of safety valve calibration, in particular to a multifunctional safety valve calibration device. Background Art

[0002] Safety valves are safety accessories for pressure vessels and pipeline equipment. Their operating reliability and performance are directly related to the safety of equipment and personnel, and are closely related to energy conservation and environmental protection. If the pressure of the safety valve is set too high, it cannot be opened in time when danger occurs, which can easily cause accidents. If the pressure is set too low, leakage and bubbling will occur, wasting energy and polluting the environment. Sometimes, the sealing surface of the safety valve will be damaged due to frequent tripping. The set pressure of the safety valve is an important parameter related to whether the safety valve can be opened in time when the equipment is under too high pressure. Safety valves must be inspected regularly according to relevant national regulations.

[0003] During use, the existing safety valve verification device passes gas into the safety valve, and then the staff checks the changes in the pressure gauge pointer to determine the sealing of the safety valve. However, during use, the slight changes in the pressure gauge pointer cannot be effectively and intuitively displayed, which is inconvenient to use and reduces practicality. Utility Model Content
