进口气动球阀
德国进口气动球阀是以压缩空气为动力,阀杆带动阀芯在阀体内转动90°可以实现全开—全闭的动作。气动调节球阀按其密封性能分为金属密封与软密封。具有结构紧凑、体积精小、运行可靠、密封性好、维修容易、安装方便、适应性强等优点。特别适合于介质是粘稠、含颗粒、纤维性质的场合。气动调节球阀广泛应用于石油、化工、教学设备、轻工、高压设备、制药、造纸等工业自动控制系统中，作远距离集中控制或就地控制。
Germany imported pneumatic ball valve is driven by compressed air, the valve stem to drive the valve in the valve body to rotate 90 degrees can be fully open - full closed action. Pneumatic ball valve according to its sealing performance is divided into metal seal and soft seal. The utility model has the advantages of compact structure, small volume, reliable operation, good sealing performance, easy maintenance, convenient installation, strong adaptability, etc.. The utility model is especially suitable for occasions where the medium is thick, containing particles and fibers. Pneumatic ball valve is widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, pharmaceutical, paper and other industrial automatic control system for remote centralized control or local control.
进口气动球阀工作原理
当气动执行器与电路和系统气源接通后，空气通过管道A或B管进入A缸（B缸）推动活塞向一端运动，从而带动旋转轴和球芯转动90°。
气动执行器顶部连动可视器，当绿色标志指向“开”字时标志阀门开启。
回信器信号灯绿灯亮时阀门处在开启位置，而红灯亮时阀门处在关闭位置。
Imported pneumatic ball valve working principle
When the pneumatic actuator is connected to the circuit and system of gas supply, air enters the cylinder through the A pipeline A or B tube (B cylinder) to push the piston to the end of movement, so as to drive the rotary shaft and the ball core rotates 90 degrees.
Pneumatic actuator linkage device when the top visible, green signs pointing to the "open" word mark valve open.
When the green light is on, the valve is in the open position and the valve is in the closed position when the red light is on.
进口气动球阀安装说明：
1、球阀前后管线已准备好。前后管道应同轴，两法兰密封面应平行。管道应能承受球阀的重量，否则管道上必须配有适当的支撑。
2、把阀前后管线吹扫干净，清除掉管道内的油污、焊渣和一切其它杂质。
3、核对球阀的标志，查明球阀完好无损。将阀全开全闭数次证实其工作正常。
4、拆去球阀两端连接法兰上的保护件。
5、检查阀孔清除可能有的污物，然后清洗阀孔。阀座与球之间即使仅有微小颗粒的异物也可能会损伤阀座密封面。
6、把阀装上管线。阀的任何一端都可装在上游端。用手柄驱动的阀可安装在管道上的任意位置。但带有齿轮箱或气动驱动器的球阀应直立安装，即安装在水平管道上，且驱动装置处于管道上方。
7、阀法兰与管线法兰间按管路设计要求装上密封垫。
8、法兰上的螺栓需对称、逐次、均匀拧紧。
9、连接气动管线（采用气动驱动器时）。
Imported pneumatic ball valve installation instructions:
1, before and after the ball valve is ready. Before and after the pipe should be coaxial, two flange sealing surface should be parallel. Piping should be able to withstand the weight of the ball valve, otherwise the pipe must be equipped with appropriate support.
2, the valve before and after the pipeline purge clean, remove the oil pipeline, welding slag and all other impurities.
3, check the ball logo, identify the ball intact. Fully open the valve fully closed several times to confirm its normal work.
4, remove the valve at both ends of the flange on the protection.
5, check the valve hole cleaning may have dirt, and then clean the valve hole. Between the valve seat and the ball even if only tiny particles of foreign body may damage the valve seat sealing surface.
6, the valve installed on the pipeline. Any end of the valve can be arranged on the upper end of the valve. The valve can be installed in any position on the pipe by the handle. But with the gear box or pneumatic drive ball valve should be installed upright, that is installed in the horizontal pipe, and the driving device in the pipeline above.
7, the valve flange and pipe flange according to the piping design requirements of the sealing gasket.
8, the flange bolts need to symmetry, successive, uniform tightening.
9, the connection of pneumatic pipeline (using pneumatic drive).
