【產(chǎn)品特點(diǎn)】：
1◆流體阻力小，其阻力系數(shù)與同長度的管段相等。
2◆結(jié)構(gòu)簡單、體積小、重量輕。
3◆緊密可靠，目前球閥的密封面材料廣泛使用塑料、密封性好，在真空系統(tǒng)中也已廣泛使用。
4◆操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。
5◆維修方便，球閥結(jié)構(gòu)簡單，密封圈一般都是活動(dòng)的，拆卸更換都比較方便。
6◆在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會(huì)引起閥門密封面的侵蝕。
7◆適用范圍廣，通徑從小到幾毫米，大到幾米，從高真空至高壓力都可應(yīng)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.
【產(chǎn)品使用說明】：
球閥安裝使用說明（1）：
1◆球閥前后管線已準(zhǔn)備好。前后管道應(yīng)同軸，兩法蘭密封面應(yīng)平行。管道應(yīng)能承受球閥的重量，否則管道上必須配有適當(dāng)?shù)闹巍?/div>
2◆把閥前后管線吹掃干凈，清除掉管道內(nèi)的油污、焊渣和一切其它雜質(zhì)。
3◆核對球閥的標(biāo)志，查明球閥完好無損。將閥全開全閉數(shù)次證實(shí)其工作正常。
4◆拆去球閥兩端連接上的保護(hù)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(huì)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(qū)動(dòng)的閥可安裝在管道上的任意位置。但帶有齒輪箱或氣動(dòng)驅(qū)動(dòng)器的球閥應(yīng)直立安裝，即安裝在水平管道上，且驅(qū)動(dòng)裝置處于管道上方。
7◆閥法蘭與管線法蘭間按管路設(shè)計(jì)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(dòng)管線（采用氣動(dòng)驅(qū)動(dòng)器時(shí)）。
10◆操作驅(qū)動(dòng)器啟、閉球閥數(shù)次，應(yīng)靈活無滯澀，證實(shí)其工作正常。
11◆按管路設(shè)計(jì)要求對管道與球閥間的法蘭結(jié)合面進(jìn)行密封性能檢查。
【 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.
