1 概述 安全阀定压是锅炉、压力容器及管道安装工程中一项重要的工作,它影响工程的运行状态及安全性。安全阀定压是锅炉安装后试运行中或压力容器及管道安装完毕试压后,以设备的压力表的示值为基准,调整安全阀达到规程规定的数值。在这之后再升压,使安全阀起跳(称试跳),验证试跳状态时压力表的示值与定压状态时压力表的示值是否一致。如不一致,应再次进行调整,直到一致为合格。
1 Overview Pressure relief valve is a boiler, pressure vessel and pipeline installation of an important task, which affects the operation of the project and safety. Safety valve fixed pressure after the boiler is installed during commissioning or after the pressure vessel and pipeline installation pressure test, the pressure gauge to indicate the value of equipment as a benchmark, adjust the safety valve to achieve the value of the rules. After that, the pressure is increased to make the safety valve take off (test jump) to verify whether the indication of the pressure gauge and the indication of the pressure gauge in the constant pressure state are the same. If inconsistent, should be adjusted again until the same as qualified.
