三位两挡控制型多路开关阀的研制及应用

三位两挡控制型多路开关阀是一种新型多路开关阀,可通过同一联控制回路输出两种不同的工作流量,从而实现油缸的两种速度切换。此多路开关阀对控制不同油缸的速度具有更好的灵活性,可以满足不同油缸作业工况差异的需要;对控制同一油缸具有更好的调速性能,能够实现同一油缸作业过程中采用不同速度,如慢速启动、快速工作等;巧妙嵌入了进油旁路节流功能,在提升液压系统调速性能和灵活性的同时,减少了发热,提高了效率。

Development and Application Of Three-Position Two-Speed Control Multi-Way Switch Valve

The three-position two-speed control type multi-way switching valve is a new type of multi-way switching valve, which can output two different working flows through the same control loop,thereby achieving two speeds of the cylinder. It has better flexibility in controlling the speed of different cylinders, meets the needs of different cylinder working conditions, has better speed control performance for controlling the same cylinder, and achieves different speeds during the same cylinder operation, such as slow speed, start-up, fast work, etc.;cleverly embedded into the oil bypass throttling function, improve the hydraulic system speed performance and flexibility, reduce heat and improve efficiency.
