功能说明 Function description

Z2FS6叠加式双单向节流阀、通过改变节流口端面大小来调节油路流量.实现流量控制。在反向时.溢流直接通过单向阀自由流动.在进口节流控制时.油液从A1口通过节流口（1）流入A2口。节流口是单向阀板（2）和节流阀芯（3）组成。通过调节螺钉（4）调节节流口（1）的大小retz品牌 Z2FS6 stacked double one-way throttle valve regulates the flow of the oil passage by changing the size of the end face of the throttle port to achieve flow control. In the reverse direction, the overflow flows freely directly through the check valve. In the inlet throttling control Oil flows from port A1 to port A2 through orifice (1). The throttle port is composed of a one-way valve plate (2) and a throttle valve core (3). Adjust the size of the throttle port (1) by adjusting the screw (4)

油液从A2口流向A1时∶压缩单向弹簧（5）打开单向阀板（2）使该阀起单向阀作用.并允许油液自由流动。改变Z2FS6叠加式单向节流阀安装位置。可实现进口节流或出口节流 When the oil flows from port A2 to port A1, compress the check spring (5) and open the check valve plate (2) to make the valve act as a check valve The oil is allowed to flow freely. Change the installation position of Z2FS6 stacked one-way throttle valve. Inlet throttling or outlet throttling can be realized

主流量限制（型号中以2Q表示）叠加式双单向节流阀为了改变执行器的速度安装于方向阀和底板之间 Main flow limit (indicated by 2Q in the model) The superimposed double one-way throttle valve is installed between the direction valve and the base plate to change the speed of the actuator

控制流量限制（型号中以1Q表示）用于控制流量限制.将叠加式双单向节流阀安装于主阀与先导阀之间 The control flow limit (1Q in the model) is used to control the flow limit. The stacked double one-way throttle valve is installed between the main valve and the pilot valve

特性 characteristic

Z2FS型叠加式单向节流阀通过改变节流口断面大小来调节油路流量.实现流量控制。在反向时.油流直接通过单向阀回油。对于10通径选用不同安装位置可实现进口节流或出口节流。对于16.22通径可选用不同的型号实现进可同时连接工作油腔的两口节流或出口节流. 可同时连接工作油腔的两条油路 Z2FS stacked one-way throttle valve regulates the flow of the oil passage by changing the size of the throttle section to achieve flow control. In the reverse direction, the oil flow returns directly through the check valve. For 10 diameters, different installation positions can be selected to achieve inlet throttling or outlet throttling. For the 16.22 drift diameter, different models can be selected to realize the two port throttling or outlet throttling that can be connected to the working oil chamber at the same time Two oil circuits of the working oil chamber can be connected at the same time
