摘　　要：针对常规抽汽供热方式中存在的最小冷却流量控制不精确、蝶阀控制抽汽量调节性能差等问题,在原有的供汽蝶阀基础上,增设了大小蝶板、阀杆,并引入了单独的执行机构,有效解决了供热蝶阀调节性能差的问题,使得供热阀的控制精度和响应速度显著提升,满足了机组在不同负荷下的运行需求。改进后的蝶阀在满足原有切缸效果的基础上,提升了机组在调峰和供热中的适应能力,为电厂进一步提高能源利用效率和运行稳定性提供了有力支持。Aiming at the problems of inaccurate control of minimum cooling flow and poor adjustment performance of butterfly valve control extraction steam volume in conventional extraction steam heating mode,on the basis of the original steam supply butterfly valve,the large and small butterfly plate and valve rod are added,and a separate actuator is introduced,which effectively solves the problem of poor adjustment performance of the heating butterfly valve,resulting in a significant improvement in the control accuracy and response speed of the heating valve,and meets the operation requirements of the unit under different loads.On the basis of satisfying the original cylinder cutting effect,the improved butterfly valve improves the adaptability of the unit in peak shaving and heating,and provides strong support for the power plant to further improve the energy utilization efficiency and operation stability.
