自力式液位控制阀关闭特性分析

Characteristic Analysis of Closing for Automatic Fluid Level Control Valve

自力式液位控制装置是一种完全不依赖外部动力的全机械式装置。为准确把握该装置在关阀过程中的水击增压,减缓水击危害,通过建立关阀时间的数学模型,编制程序计算得到了关阀时间值。通过分析关阀特性,说明该装置能有效控制关阀时间,防水击发生。

The automatic fluid level control equipment is independent of any exterior drive and adopted a mechanical structure. In order to holds the pressure, producing in closing time for valve, the closing time by establish mathematical model and using computer program was calcu-lated. Then a conclusion by analyzed closing characteristic was gained, the device has a good control in closing time and could lighten water hammer pressure well.
