一种无级调节机电液联控闸阀的设计与研究

Design and Research of a Stepless Regulating Electro-Hydraulic Combined Control Drainage Gate Valve

为改善传统液控闸阀启闭速度无法调节、容易引发水锤和在突发断电情况可操作性差的问题,利用模块化设计方法设计一种无级调节机电液联控闸阀。提出闸阀的机械结构和液压系统设计方案,建立闸阀的机电液联合仿真模型,优化了影响闸阀性能的关键参数。结果表明:当液控单向阀开启压力取0.8 MPa,双向节流调速阀的开阀节流阀孔径取1.4 mm,关阀节流阀孔径取1.2 mm,既能实现闸阀的稳定工作,又不会影响排水效率。最后通过实验样机验证了闸阀设计方案的可行性和参数选择的合理性,能够为该类闸阀的继续开发和应用提供参考。

In order to solve the problem that the opening and closing speed of traditional hydraulic control gate valve cannot be adjusted,easy to cause waterhammer,and cannot cope with the sudden power failure,a stepless electromechanical hydraulic combined control drainage gate valve was designed.The mechanical structure and hydraulic system design scheme of the gate valve were proposed,and the electromechanical hydraulic co-simulation model of the gate valve was established to optimize the key parameters affecting the performance of the gate valve.The results show that:when the opening pressure of the hydraulic control check valve is set at 0.8 MPa,the opening valve throttle valve aperture is set at 1.4 mm,and the closing valve throttle valve aperture is set at 1.2 mm,the stable operation of the gate valve can be realized without affecting the drainage efficiency.Finally,the feasibility of the design scheme of the gate valve and the rationality of the parameter selection are verified by experimental prototype.It provides reference for the further development and application of this kind of gate valve.
