【摘要】 在各种流体装置中,调节阀起到重要的控制作用,被国民经济各个部门广泛应用[1]。活塞式流量调节阀具有优良的流量、压力调节特性,并且有良好的动态防振动性能,同时能有效防止气蚀损伤。本文基于博纳斯威股份有限公司提供的DN1200网眼型鼠笼和长孔型鼠笼活塞式流量调节阀的流场三维模型,通过流体动力学数值计算,对比这两种流量调节阀的内部流场,确定这两种调流阀在设计参数条件下的通流能力,从而为活塞式流量调节阀的设计及选型奠定一定的基础。更多还原

【Abstract】 In various fluid installations, the regulating valve plays an important role in control and is widely used by various sectors of the national economy[1]. The piston flow regulating valve has excellent flow and pressure regulation characteristics, and has good dynamic anti-vibration performance, and can effectively prevent cavitation damage. Based on the three-dimensional model of the flow field of the DN1200 mesh squirrel cage and the long hole squirrel piston flow control valve provided by BENSV VALVE STOCK Co, LTD., the internal flow of the two flow regulating valves is compared by hydrodynamic numerical calculation. The field determines the flow capacity of the two flow regulating valves under the design parameters, which lays a foundation for the design and selection of the piston flow regulating valve.更多还原
