【摘要】 顺序阀就其控制方式说分为两种:一种是用顺序阀本身进口压力油进行控制的,称为内控顺序阀;另一种是用外部压力油进行控制的,称为外控顺序阀。内-外控顺序阀是结合了内控和外控两种控制方式于一体的一种新型顺序阀。利用这个控制功能,在一个工作循环周期内,该阀可以根据负载情况来控制背压的大小,根据工况的不同来控制背压的有无,即可以避免因负载变化引起的冲击和振动,使液压缸运动平稳,又可以达到节能的效果。更多还原

【Abstract】 A new load dependent backpressure valve is a Sequence Valve which can be controlled both by internal pressure and external pressure.Throw this control properties,whether the backpressure force is big or small and whether it has or not can be both controlled by the Load dependent backpressure valve according to the load to avoid impact and shake,by do this,the cylinder can be move placidly and saving energy.更多还原
