Questions regarding valve calibration
Thread Content
Recently, the calibration deadline for one of the company’s safety valves is approaching. I don’t have much experience working with valves. May I ask everyone: aside from safety valves, which other types of valves need to be taken to qualified authorities for regular calibration?
Thank you, OP. Does anyone else know?
**Are there any relevant standards that specify which valves need to be sent to the relevant authorities for calibration?
The breathing valve also falls under the category of breathing valves; it is a safety valve for low-pressure systems. Such safety valves allow air to escape but not be drawn in, and they are all considered special types of safety equipment accessories. Like elevators, they belong to the category of safety devices and thus require supervision at the local level. Therefore, they need to be regularly calibrated by the local pressure vessel inspection agency, while other valves do not have such requirements! Thank you, that’s all I know. I work at the 11th Aerospace Institute, selling safety valves.
