对JJG 52-2013《弹性元件式一般压力表、压力真空表和真空表检定规程》中耐压检定的探讨

Discussion on Pressure Endurance Verification of JJG 52-2013 "Verification Regulation of Elastic Element Pressure Gauges, Pressure-Vacuum Gauges and Vacuum Gauges for General Use"

弹性元件式压力表是将管道压力通过压力表弹性元件和传动机构在表盘上指示出现场压力的示值,广泛应用于生产企业、燃气管道。涉及安全类的压力表属于强制检定仪表,在检定过程中,测量上限需耐压3min,而对于面大量广的压力表检定工作,很多人不解甚至觉得没有必要,本文将对此进行讨论。

Elastic element pressure gauge is to make the pipe pressure through the pressure gauge elastic element and transmission mechanism on the dial to indicate the field pressure.It is widely used in production enterprises and gas pipelines.Pressure gauges related to safety are compulsory verification instruments, and the upper limit of the measurement needs to withstand pressure for 3 min in the verification process.Many people do not understand the verification work of pressure gauges with large and wide surface, or even think it is unnecessary.This article will discuss this.
