根据工程的需要,利用液压差值和调压弹簧作用力设计的液控截止阀,实现阀门的自动启闭,给工业自动化生产提供便利的同时更节省了时间和生产成本。从理论的角度建立阀的力学和流量数学模型,并对其内部流场进行模拟分析,为阀类件的设计提供理论支持。 According to the needs of the project, the use of hydraulic pressure difference and pressure regulating spring designed hydraulic control valve, to achieve automatic valve opening and closing, to facilitate the production of industrial automation but also save time and production costs. The mathematical model of valve mechanics and flow rate is established from the theoretical point of view, and its internal flow field is simulated and analyzed, providing theoretical support for the design of valve parts.
