【产品特点】：
1◆流体阻力小，其阻力系数与同长度的管段相等。
2◆结构简单、体积小、重量轻。
3◆紧密可靠，目前球阀的密封面材料广泛使用塑料、密封性好，在真空系统中也已广泛使用。
4◆操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。
5◆维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
6◆在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
7◆适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
【 features 】 :
1 pieces small fluid resistance, the resistance coefficient with section of equal length.
2 pieces of simple structure, small volume, light weight.
3 pieces tightly and reliable, and the widespread use of plastic ball valve sealing surface of materials, sealing is good, have been widely used in the vacuum system.
4 pieces of convenient operation, opening and closing rapidly,
5 pieces convenient maintenance, ball valve has simple structure, sealing ring are generally active, removal of replacement is more convenient.
6 pieces in full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.
7 pieces applicability is wide and sizes from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
【产品使用说明】：
球阀安装使用说明（1）：
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）。
10◆操作驱动器启、闭球阀数次，应灵活无滞涩，证实其工作正常。
11◆按管路设计要求对管道与球阀间的法兰结合面进行密封性能检查。
【 product use 】 :
1 pieces ball valve before and after the line has been ready. Before and after the pipe shall be concentric, two flange sealing surface should be parallel. Pipe should be able to bear the weight of the ball valve, otherwise the line must be equipped with appropriate support.
2 pieces before and after the valve pipe purging clean, remove all oil pipe, welding slag, and other impurities.
3 pieces to check ball valve, check valve is in good condition. Will be fully open valve full close several times to confirm they work.
4 pieces on the other side of down ball valve connection protection.
5 pieces to check the valve hole clearance may have dirt, and then clean the valve hole. Even if only small particles of foreign bodies between the seat and the ball may also damage the seat sealing surface.
6 pieces put valve on the pipeline. Any end of the valve can be installed at the upstream end. Handle drives the valve can be installed on the pipeline at any position. But with a gear box or pneumatic actuator ball valve shall be installed upright, is installed in a horizontal pipe, and drive in the pipe above.
7 pieces between the valve flange and pipe flange gaskets fitted according to the requirements of pipeline design.
8 mixer flange bolts need to be symmetrical, successive, evenly tighten.
9 pieces connect pneumatic pipe when using the pneumatic drive （）.
10 pieces actuator ball valve opening and closing operation several times, should be no sluggish acerbity, confirmed that they work.
11 pieces according to the requirements of pipeline design and ball valve between the flange joint surface of the pipes to seal performance tests.
