气动防爆法兰球阀 气动防爆法兰球阀

气动防爆法兰球阀NTQ641(F、H)-（C、R、R）-PN16、25、40

 气动防爆法兰球阀是一种(球体)绕垂直于通道轴旋转90°的阀门，其由活塞式双作用或单作用(弹簧复位式)气动执行器和O型阀结构组成，配用附件电磁阀、空气过滤减压器、限位开关(阀位回讯器)或电-气阀门定位器，实现对工艺管路中流体介质的自动调节控制或二位切断控制。

产品特点 
1．气动球阀流体阻力小，是所有阀类中流体阻力zui小的一种，启闭迅速方便，以压缩空气为动力，通过活塞齿条，齿轮的机械传动阀杆，以角行程输出的扭矩转动球体 0~90°，就能快速完成启闭动作或调节动作。球芯通道平整光滑，不易沉积介质，可以进行管线式通球。结构简单、重量轻、密封性能好。是自动化控制系统中仪表的执行单元。 
  2．采用电-气阀门定位器，以电信号和压缩空气为动力，接受控制系统输入的0-10mA DC或4-20mA DC电流信号，由调节器将压缩空气，转换成气源压力信号输入输出，改变球芯的旋转角度，可实现比例调节动作。 
  3．采用电磁换向阀、阀位回讯器，以AC220V或DC24V电源电压和压缩空气作动力，实现对流体介质的快速二位切断控制。 
  4．气动执行机构采用活塞式气缸及曲臂转换结构，输出力矩大，体积精小，采用全密封防水设计防护等级高。气缸体采用镜面气缸，无油润滑，磨擦系数小、耐腐蚀、具有*的耐用性及可靠性。所有传动轴承均采用边界自润滑轴承无油润滑，确保传动轴不摩损。
