摘　　要：为实现消防信号蝶阀信号转换功能的快速无损测试,利用压差和流量的相关性,提出了信号转换功能的等效试验方法,并对不同的消防信号蝶阀进行了等效试验和数据分析,确定了信号转换流量和等效转动角度对应关系的合理性。等效方法解决了目前信号转换功能测试中高检测资源要求、高消耗及安装损坏等问题,大幅降低了测试时间及成本,提高了测试效率。In order to realize the fast and nondestructivetesting of the signal conversion function of the fire signal butterfly valves,the equivalent test method of signal conversion function of fire signal butterfly valve is researched.The equivalent test and data analysis of different fire signal butterfly valves is carried out by using the correlation of differential pressure and flow rate,and the rationality of the corresponding relationship between the signal conversion flow and the equivalent rotation angle is determined.This equivalent method solves the problems of high detection resource requirement,high consumption and installation damage in the current signal conversion function test,and greatly reduces the testing time and cost and improves the test efficiency.
