摘要
针对浮子式单向阀在使用过程中可能出现阀芯卡紧现象,通过三维模型进行几何构型,分析同时利用有限元分析以及对照组实验等方法建立阀体内径不变,阀芯棱宽为2 mm的浮子式单向阀与4 mm的浮子式单向阀时其在阀体内的受力情况.通过试验对比结构相同、自重不同的阀芯对单向阀状态切换时的影响.结果表明:在满足最小流通面积的情况下,阀芯棱宽为4 mm的浮子式单向阀相较于2 mm的浮子式单向阀其受冲击时能较好抵抗变形,且能有效避免阀芯卡紧现象;相同压差下,阀芯自重越重的在阀件状态装换时阀芯处于悬浮态时间越短.
Aiming at the phenomenon that the valve core may be clamped during the use of the float check valve,the three-dimensional model is used to analyze the geometric configuration,and the internal stress of the 2mm wide spool and 4mm wide floating ball check valve is established through finite element analysis and control group experiments.The influence of different valve elements with the same structure and different dead weight on the state switching of one-way valve is compared through experiments.The results show that the float check valve with 4mm edge width of the valve core can resist deformation better than 2mm under the condition of meeting the minimum flow area,and can effectively avoid the clamping phenomenon of the valve core;Under the same pressure difference,the heavier the self weight of the valve element,the shorter the suspension time of the valve element when the valve element is installed and replaced.
