介绍一种经过优化设计的液压插头,它采用四条通路均使用类似阀板阀座同时密封的方式,既可以同时连通四路液压通道(简称四通快插),同时还具有密封性能好、可靠性高、液压执行效率高的优点。通过对四通快插机械强度、密封件滑动阻力等关键技术指标的分析计算及相关的性能测试,验证了产品在不同工作条件下的可靠性。 An optimized hydraulic plug is introduced, which adopts four ways to seal at the same time with valve plate and valve seat, which can connect four hydraulic channels at the same time (also referred to as four-way quick plug), and also has good sealing performance and reliability High performance, high hydraulic efficiency advantages. The reliability of the product under different working conditions was verified by the analysis and calculation of the key technical indicators such as mechanical strength and sliding resistance of the seal and related performance tests.
