蝶型弹簧全量型安全阀整定装置的应用

蝶型弹簧全量型安全阀的整定是火电厂锅炉机组安装及大修期间一项非常重要的工作,它的准确性及灵敏度直接关系到机组运行的安全、可靠性。以往常规的整定方法是采用实跳法,不仅耗费较大,而且也易造成设备损坏及人身伤害。在龙岗电厂的机组试运期间,由哈尔滨锅炉厂协助采用专用整定工具进行了所有安全阀的整定,整定精确度完全满足ASME 标准要求,劳动强度也大为降低,收到了较好的效果。

Application of Setting Device for Butterfly Spring Full Range Type Safety Valve

The setting of the butterfly spring full-rang type relief valve is an important job during installation and overhaul of the boiler units in the fossil fired power plants, whose accuracy and sensitivity has direct relation to safety and reliability of the unit operation. The conventional setting method is the actual jumping method, which is of high cost and easy to cause damage of equipment or injury to people. During trial operation of units in Longgang power plant the setting for all relief valves were carried out with special setting tool in assistance of Harbin Boiler Works. The setting accuracy has completely met with the requirements in ASME standard and the labor strength has been greatly reduced with ideal results.
