气动塑料阀门执行器装配说明

气动塑料阀门执行器装配(即通常所说的气动头),气动塑料阀门执行器又简称气动执行机构或气动装置,是利用压缩空气的气源压力来驱动启闭或调节阀门的执行装置,主要由气缸,活塞,齿轮轴,端盖,密封件,螺丝等组成,气动塑料阀门执行器装配一般与各类阀门配套使用,其中还包括开度指示,行程限位,电磁阀,定位器,气动元件,信号反馈等部件组成,阀门的开,关,开多少,关多少,均用压缩空气来进行控制。阀门气动执行器工作原理,气动执行器根据作用形式可分为单作用和双作用,双作用执行器表现为气开气关式,即通气打开,通气关闭,失去气源时,无动作,停留原位,而单作用执行器具有弹簧复位的功能,气动塑料阀门执行器装配一般有常闭型和常开型,即通气打开,失去气源时,自动复位到初始状态,在危险的工况中使用较多,可在失去气源货出现突发故障时,将阀门快速关闭或打开。

双作用气动塑料阀门执行器装配工作原理:
Working principle of the double-acting pneumatic actuators:
气动塑料阀门执行器装配当气源压力从气口(2)进入气缸两活塞之间中腔时,使两活塞分离向气缸两端方向移动,两端气腔的空气通过气口(4)排出,同时使两活塞齿条同步带动输出轴(齿轮)逆时针方向旋转,反之气源压力从气口(4)进入气缸两端气腔时,使两活塞向气缸中间方向移动,气动塑料阀门执行器装配中间气腔的空气通过气口(2)排出,同时使两活塞齿条同步带动输出轴(齿轮)顺时针方向旋转。(如果把活塞相对反方向安装,输出轴即变为反向旋转)
When the air pressure from the port (2) into the cylinder between the pistons lumen, separate the two piston to move on both ends of the cylinder, gas cavity on both ends of the air through the intake (4), at the same time to synchronize two piston rack drives the output shaft (gear) counterclockwise. And air pressure from the port (4) into the chamber on both ends of the cylinder, the two direction among the piston to the cylinder, the air cavity in the middle of the air through the intake (2), at the same time to synchronize two piston rack drives the output shaft rotate clockwise (gear). (if the piston in the opposite direction installation, output shaft into a reverse rotation)

单作用气动执行器工作原理,带弹簧复:
Working principle of the single acting pneumatic actuator with spring:
当气源压力从气口(2)进入气缸两活塞之间中腔时,使两活塞分离向气缸两端方向移动,迫使两端的弹簧压缩,两端气腔的空气通过气口(4)排出,同时使两活塞齿条同步带动输出轴(齿轮)逆时针方向旋转,在气源压力经过电磁阀换向后,气缸的两活塞在弹簧的弹力下向中间方向移动,中间气腔的空气从气口(2)排 出,同时使两活塞齿条同步带动输出轴(齿轮)顺时针方向旋转。(如果把活塞相对反方向安装,弹簧复位时输出轴即变为反向旋转)
From port when air pressure between two piston (2) into the cylinder lumen, separate the two piston to move on both ends of the cylinder, force on both ends of the spring compression, both ends of the air chamber through the intake (4), at the same time to synchronize two live plug rack drives the output shaft (gear) counterclockwise. In the air pressure after reversing solenoid, two piston cylinder in the middle of the spring under the elastic to direction, from the chamber in the middle of the air intake (2) out, at the same time to synchronize two piston rack drive output shaft rotate clockwise (gear). (if the piston relative direction installation, spring reset output shaft into a reverse rotation)
