進口氣動球閥
德國進口氣動球閥是以壓縮空氣為動力,閥桿帶動閥芯在閥體內轉動90°可以實現全開—全閉的動作。氣動調節球閥按其密封性能分為金屬密封與軟密封。具有結構緊湊、體積精小、運行可靠、密封性好、維修容易、安裝方便、適應性強等優點。特別適合于介質是粘稠、含顆粒、纖維性質的場合。氣動調節球閥廣泛應用于石油、化工、教學設備、輕工、高壓設備、制藥、造紙等工業自動控制系統中，作遠距離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.
進口氣動球閥工作原理
當氣動執行器與電路和系統氣源接通后，空氣通過管道A或B管進入A缸（B缸）推動活塞向一端運動，從而帶動旋轉軸和球芯轉動90°。
氣動執行器頂部連動可視器，當綠色標志指向“開”字時標志閥門開啟。
回信器信號燈綠燈亮時閥門處在開啟位置，而紅燈亮時閥門處在關閉位置。
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.
進口氣動球閥安裝說明：
1、球閥前后管線已準備好。前后管道應同軸，兩法蘭密封面應平行。管道應能承受球閥的重量，否則管道上必須配有適當的支撐。
2、把閥前后管線吹掃干凈，清除掉管道內的油污、焊渣和一切其它雜質。
3、核對球閥的標志，查明球閥完好無損。將閥全開全閉數次證實其工作正常。
4、拆去球閥兩端連接法蘭上的保護件。
5、檢查閥孔清除可能有的污物，然后清洗閥孔。閥座與球之間即使僅有微小顆粒的異物也可能會損傷閥座密封面。
6、把閥裝上管線。閥的任何一端都可裝在上游端。用手柄驅動的閥可安裝在管道上的任意位置。但帶有齒輪箱或氣動驅動器的球閥應直立安裝，即安裝在水平管道上，且驅動裝置處于管道上方。
7、閥法蘭與管線法蘭間按管路設計要求裝上密封墊。
8、法蘭上的螺栓需對稱、逐次、均勻擰緊。
9、連接氣動管線（采用氣動驅動器時）。
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).
