Background
At present, three types of safety valve checking exist, namely, offline checking, direct online checking and online checking by using an online checking instrument. The three modes are characterized. The off-line verification is safe and reliable, and in some cases, the off-line verification is needed, but the efficiency is low, and off-line deviation and the like can be generated for a spring type safety valve of the boiler. The direct on-line verification is simple and convenient, but the pressure is provided by the system, and the fluctuation and abnormal working condition of the system can be caused, so that the danger exists for equipment and personnel. The online check meter is high in online check efficiency and safe, but is only suitable for the spring type safety valve. The medium-low pressure thermoelectric practice boiler and high-temperature water tank are commonly used as lever-type (heavy hammer) safety valves, and due to the heavy structure of the safety valves and the characteristics of devices using the valves, the safety valves are not suitable for off-line verification, and the direct on-line verification is commonly used currently, so that people and devices are unsafe.
