pneumatic valve pneumatic actuator
pneumatic valve pneumatic actuator is safe, reliable, low cost, convenient operation and maintenance, is a major branch of pneumatic valve drive structure. The pneumatic actuator in explosion-proof requirements are applied more. Pneumatic valve pneumatic actuator USES air supply work pressure is low, generally no more than. MPa。 Shoulds not be too great for structure size, total thrust and pneumatic valve pneumatic actuators can't be large. A pneumatic actuators, pneumatic valves conditions of use conditions of use
air pressure
. ~。 ( MPa)
the environment temperature and medium temperature
~ ( ℃)
the piston speed linear velocity and blade diameter
~ ( mm/s)
- electromagnetic control input signal current mA
2, the classification of the pneumatic valve pneumatic actuator pneumatic valve pneumatic actuators according to its structural characteristics are divided into three types: diaphragm cylinder or pneumatic actuators, pneumatic actuators, oscillating pneumatic actuators. In addition to the pneumatic motor type pneumatic actuators. 气动执行器分类

三、各类气动执行器的结构特点气动执行器结构特点
型式
特点
薄膜式
行程短,<mm,结构紧凑,灵活,无手动机构
气缸式
行程长,必要时需加缓冲机构,出力不够采用双气缸结构,有手动和手气动切换结构
摆动式
结构简单,成本低,往复运动直接变成旋转运动
气动马达式
可以直接代替气动阀门电动装置的电动机而成为气动执行器,因而可具有电动装置的力矩控制等功能,但结构复杂
