双作用执行器的选型:
在正常操作条件下，双作用执行器考虑的安全系数为20%-30%。
示例：
阀门力矩=100nm
安全力矩=100×(1+30%)=130nm
气源压力=5bar
对照双作用力矩表，选配双作用执行器最小规格为rt160da，扭矩为165.3nm.

sizing: double acting actuator

the suggested safety factor for double acting actuators under normal working conditions is 20%-30%.

example:

the torque needed by valve=100n.m

the torque considered safety factor (1+30%)=130n.m，

air supply=5bar

according to the above table, we can choose the minimum model is rt160da. torque is165.3nm .

air to port a forces the pistons outwards, causing the springs to compress, the pinion turns counterclockwise while air is being exhausted from port b.

loss of air pressure on port a, the stored energy in the springs forces the pistons inwards. the pinion turns clockwise while air is being exhausted from port a.

a口进气,压缩空气克服弹簧力，推动活塞向外运动，执行器输出轴逆时针转动(0°→90°)，b口排气；

执行器失气，活塞在弹簧力的作用下向内运动，执行器输出轴顺时针转动(90°→0°)，a口排气。

单作用执行器的选型
在正常情况下考虑安全系数为30％-40％
例如:阀门力矩为80nm
安全力矩为:80*(1+30％)=104nm
气源压力为5bar 对照单作用输出力矩表,可以选rt435srk10
压缩空气对应的力矩为: 0°=256, 90°=169
此时弹簧输出的力矩对应为90°=258, 90°=172，所有输出力矩均大于我们需求。
