摘要
针对目前国内现有阀门流量测试装置测试范围小、功能单一、精度不高、自动化水平低,不能很好满足阀门技术高速发展需求的问题,研制了阀门流量特性综合测试系统,并对循环水源、动力系统、稳压装置、测试管路、流量校验系统、数据采集系统、自动控制系统等测试系统组成部件设计进行了详细介绍,该测试系统具有阀门的流量系数、流阻系数、固有流量特性、流量的校验以及阀门微小流量测试等综合检测功能。经应用表明,该系统测试能力大、测试精度高、自动化程度高,流量误差小于实际流量的±2%,压差误差小于实际压差的±2%。因此,该测试系统可满足目前阀门技术大型化、高参数、微小流量调节等测试技术的需要。
In view of the problems that the current domestic valve flow test device can not well meet the needs of the rapid development of valve technology,such as small test range,single function,low precision and low automation level,a comprehensive test system for valve flow characteristics was developed,and the design of components of the test system such as circulating water source,power system,pressure stabilizing device,test pipeline,flow calibration system,data acquisition system and automatic control system was introduced in detail.The test system has the comprehensive detection functions of valve flow coefficient,flow resistance coefficient,inherent flow characteristics,flow verification and valve micro flow test.The actual application shows that the system has large testing capacity,high testing accuracy and high degree of automation,and the error of flow rate and pressure difference is less than±2%.Therefore,the test system can meet the needs of large-scale valve technology,high parameter,micro flow regulation and other test technologies.
