進口三位式氣動執(zhí)行器工作原理 Working principle of three position pneumatic actuator

180°彈簧復位氣動執(zhí)行器在兩端設計有彈簧組件，適用于0°-90°-180° 之間往復運動操作，在失去氣源壓力（或故障）時通過彈簧回位至90° 位置。 在全開位置180°和全關位置0°以標準方式在外部可以準確調整±4°  The 180 ° spring return pneumatic actuator is designed with spring components at both ends, which is suitable for reciprocating operation between 0 ° -90 ° -180 °, and returns to the 90 ° position through the spring in case of loss of air supply pressure (or failure). It can be accurately adjusted ± 4 ° externally in a standard way at 180 ° in the fully open position and 0 ° in the fully closed position.

1、從90°-180° 當氣源壓力從氣口（2）進入氣缸兩活塞 中間腔時，使兩活塞分離向氣缸兩端方向 移動，迫使兩端的彈簧組壓縮，兩端氣腔 的空氣通過氣口（4）排出，同時使兩活塞 齒條同步帶動輸出軸（齒輪）逆時針方向 旋轉到達180° From 90 ° -180 °, when the air source pressure enters the middle chamber of the two pistons of the cylinder from the air port (2), the two pistons will separate and move towards the two ends of the cylinder, forcing the spring groups at both ends to compress, and the air in the air chambers at both ends will be discharged through the air port (4). At the same time, the two piston racks will synchronously drive the output shaft (gear) to rotate counterclockwise to 180 °

2、從90°-0° 當氣源壓力從氣口（4）進入氣缸兩端氣腔 時，使兩活塞向氣缸中間方向移動，迫使 兩端的彈簧組壓縮，中間氣腔的空氣通過 氣口（2）排出，同時使兩活塞齒條同步帶 動輸出軸（齒輪）順時針方向旋轉到達0° From 90 ° -0 °, when the air supply pressure enters the air chambers at both ends of the cylinder from the air port (4), the two pistons move towards the middle of the cylinder, forcing the spring groups at both ends to compress, and the air in the middle air chamber is discharged through the air port (2). At the same time, the two piston racks synchronously drive the output shaft (gear) to rotate clockwise to 0 °

3、從失去氣源壓力的操作  Operation from loss of supply pressure

當位置在180°：在氣口（2）失去空氣壓力 或電磁閥斷電時，彈簧推力迫使活塞向氣缸 中間方向移動，產生順時針方向旋轉至90° 位置  When the position is 180 °: when the air pressure is lost at the air port (2) or the solenoid valve is powered off, the spring thrust forces the piston to move towards the middle of the cylinder, resulting in clockwise rotation to the 90 ° position

當位置在0°：在氣口（4）失去空氣壓力或 電磁閥斷電時，彈簧推力迫使活塞向氣缸 兩端方向移動，產生逆時針方向旋轉至90° 位置  When the position is 0 °: when the air pressure is lost at the air port (4) or the solenoid valve is powered off, the spring thrust forces the piston to move towards both ends of the cylinder, resulting in counterclockwise rotation to the 90 ° position

進口三位式氣動執(zhí)行器開關位置原理 Switch position principle

三位置氣動執(zhí)行器有兩種型號0°-45°-90°和0°-90°-180°，在氣口進氣后 活塞向兩端運動被兩端設計有輔助活塞產生機械限制來實現(xiàn)中間位置； 可直接利用外面兩端調節(jié)螺栓很容易調節(jié)中間位置角度， 如20°、30°、50°、75°和95°、120°、130°、 150°、175°等。There are two types of three position pneumatic actuators: 0 ° -45 ° -90 ° and 0 ° -90 ° -180 °. After the air inlet, the piston moves to both ends, which is mechanically limited by auxiliary pistons designed at both ends to achieve the middle position; The adjusting bolts at both ends of the outside can be directly used to easily adjust the angle of the middle position, such as 20 °, 30 °, 50 °, 75 ° and 95 °, 120 °, 130 °, 150 °, 175 °, etc

三位置氣動執(zhí)行器的操作需要設計一套電磁閥控制回路系統(tǒng)來完成操作，其控制原理如下：The operation of the three position pneumatic actuator requires the design of a solenoid valve control loop system to complete the operation. Its control principle is as follows:

位置1（中間位置）：Position 1 (middle position)

氣源壓力同時進入2口和D口，空氣從4口 和C口排出，2口作為內部活塞移動，D是 通過輔助活塞推桿限制內部活塞定位在 預定的中間位置。The air supply pressure enters port 2 and port d at the same time, and the air is discharged from port 4 and port C. port 2 moves as an internal piston, and port D restricts the internal piston to be positioned in the predetermined middle position through the auxiliary piston push rod.

位置2（全開位置）Position 2 (full open position)

氣源壓力同時進入2口和C口，空氣從4口 和C口排出，2口的內部活塞繼續(xù)移動，C口 為解除輔助活塞推桿限制定位，使內部 活塞順利到達全開位置。The air supply pressure enters port 2 and port C at the same time, and the air is discharged from port 4 and port C. the internal piston of port 2 continues to move. Port C is positioned to release the limit of the auxiliary piston push rod, so that the internal piston can reach the full open position smoothly.

位置3（全關位置）Position 3 (fully closed position)

氣源壓力進4口，空氣從2口排出，內部活塞 向中間方向移動到達全關位置。 可提供0°-45°-90°彈簧回位型號規(guī)格， 在斷氣斷電時（或氣源故障），通過彈簧 迫使內部活塞回位到全關位置。The air supply pressure enters 4 ports, the air is discharged from 2 ports, and the internal piston moves to the middle direction to reach the fully closed position. Models and specifications of 0 ° -45 ° -90 ° spring return can be provided. In case of air and power failure (or air supply failure), the internal piston is forced to return to the fully closed position by the spring.
