V-TORK VT140D双作用气动执行器

　　V-TORK VT140D双作用气动执行器

　　V-TORK气动执行器可匹配蝶阀，球阀等角程阀门在石油化工、燃气设备、核工业、电力装备、环保水处理、暖通空调、钢 铁冶金、工业窑炉、罐装设备、酿酒设备、干燥设备、真空设备、表面处理、生物制药、食品机械、纺织印染、造纸等行业中得到***的使用。

　　V-TORK VT140D双作用气动执行器齿轮齿气动执行机构集设计紧凑、简易组合、***定制等特点于一体，该系列产品采用***的***活塞设计，传动***，输出扭矩大，装配附件符合NAMUR***，其合理的结构设计和优良的工程特性都保证了优越的产品使用寿命。

　　设计规范：

　　■齿轮齿条双活塞对称结构设计，动作快速平稳，精度高，输出功率大，通过简单的改变活塞装配位置可得到反方向旋转。

　　■Rack and pinion double-piston symmetrical structure design, fast and stable action, high precision, large output power, by simply changing the piston assembly position can get the opposite direction of rotation.

　　■挤压的***铝合金缸体，经***加工的内孔和外部表面进行硬质阳极氧化处理（特殊情况下阳极氧化+特氟隆涂层），使用寿命更长，摩擦系数低。

　　■Extruded high-quality aluminum alloy cylinder body, the inner hole and outer surface of the precision machined are hard anodized (anodized + Teflon coating in special circumstances), which has a longer service life and low friction coefficient.

　　■一体式设计，所有的双作用和单作用执行器型号，都具有相同的缸体和端盖，很方便通过加装弹簧或拆除弹簧来改变作用方式。

　　■One-piece design, all double-acting and single-acting actuator models have the same cylinder body and end cover, which makes it easy to change the mode of action by adding or removing springs.

　　■组合式预符荷安全弹簧组，不论在装配过程或使用现场中，都能方便而安全的安装或增减弹簧数量。

　　■Combined pre-loaded safety spring group, no matter in the assembly process or use site, it can be convenient and safe to install or increase or decrease the number of springs.

　　■外部侧面两个单独调节螺钉对于已安装在阀门上的执行器更是***方便，调节阀开和阀关位置，如需全行程调节时则另外在两个端盖处配置较长调节螺钉。

　　■Two separate adjustment screws on the outer side are more accurate and convenient for the actuators that have been installed on the valve. The valve opening and valve closing positions are adjusted. If full stroke adjustment is required, a longer adjustment screw is provided at the two end covers.

　　■多功能位置指示器，现场可视化指示，符合VID/VIE3845、NAMUR标准槽，能安装并输出所有附件，如限位开关盒、电气、位置传感器

　　■Multi-function position indicator, on-site visual indication, conforms to VID/VIE3845, NAMUR standard slot, can install and output all accessories, such as limit switch box, electric positioner, position sensor

　　■气源接口符合NRMAR标准，可直接安装NUMAR标准电磁阀。

　　■The air source interface conforms to the NRMAR standard, and the NUMAR standard solenoid valve can be directly installed.

　　■齿条背面的复合材料轴瓦和活塞导向环以及输出轴的轴承等为防止金属对金属的摩擦，并且增加润滑,使其低摩擦、长寿命。

　　■The composite material bearing bush and piston guide ring on the back of the rack and the bearing of the output shaft prevent metal-to-metal friction and increase lubrication to make it low friction and long life.

　　■所有的紧固件均采用不锈钢材料，长期抗腐蚀。

　　■All fasteners are made of stainless steel, long-term corrosion resistance.

　　■连接部分符合******规范ISO5211，DIN3337（F03-F25）使产安装具有互换性、通用性。

　　■The connection part complies with the new international standard specification ISO5211, DIN3337 (F03-F25), which makes the product installation interchangeable and universal.
