進(jìn)口銅球閥優(yōu)選德國(guó)洛克品牌

進(jìn)口銅球閥結(jié)構(gòu)特點(diǎn)：

1、流體阻力小，球閥是所有閥類中流體阻力最小的一種，即使是縮徑球閥，其流體阻力也相當(dāng)小。

2、開(kāi)關(guān)迅速、方便，只要閥桿轉(zhuǎn)動(dòng)90°，球閥就完成了全開(kāi)或全關(guān)動(dòng)作，很容易實(shí)現(xiàn)快速啟閉。

3、密封性能好。球閥閥座密封圈一般采用聚四氟乙烯等彈性材料制造，易于保證密封，而且球閥的密封力隨著介質(zhì)壓力的增加而增大。

4、閥桿密封可靠。球閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)，因此閥桿的填料密封不易被破壞，而且閥桿倒密封的密封力隨著介質(zhì)壓力的增加而增大。

5、球閥的啟閉只做90°轉(zhuǎn)動(dòng)，故容易實(shí)現(xiàn)自動(dòng)化控制和遠(yuǎn)距離控制，球閥可配置氣動(dòng)裝置、電動(dòng)裝置、液動(dòng)裝置、氣液聯(lián)動(dòng)裝置或電液聯(lián)動(dòng)裝置。

進(jìn)口銅球閥規(guī)格參數(shù)：

1.口徑范圍:DN15-DN100

2.公稱壓力：1.6Mpa

3.閥體材質(zhì):黃銅

4.球芯材質(zhì):黃銅

5.閥門密封: PTFE

6.連接方式: 螺紋連接

7.工作溫度:-20℃≤t≤150℃

8.工作介質(zhì):水、非腐蝕性液體、飽和蒸汽（≤0.6MPa）

9.連接方式:G螺紋/NPT螺紋/法蘭

進(jìn)口銅球閥安裝說(shuō)明：

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?

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(duì)球閥的標(biāo)志，查明球閥完好無(wú)損。將閥全開(kāi)全閉數(shù)次證實(shí)其工作正常。

4、拆去球閥兩端連接法蘭上的保護(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(duì)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(wú)滯澀，證實(shí)其工作正常。

11、按管路設(shè)計(jì)要求對(duì)管道與球閥間的法蘭結(jié)合面進(jìn)行密封性能檢查。

Installation instructions for imported copper ball valve:
1. The pipeline before and after the ball valve is ready. The front and rear pipes shall be coaxial, and the sealing surfaces of the two flanges shall be parallel. The pipe should be able to bear the weight of ball valve, otherwise the pipe must be equipped with proper support.
2. Purge the pipeline before and after the valve to remove the oil, welding slag and all other impurities in the pipeline.
3. Check the mark of the ball valve and find out that the ball valve is intact. Fully open and close the valve several times to confirm its normal operation.
4. Remove the protective parts on the connecting flanges at both ends of the ball valve.
5. Check the valve hole, remove possible dirt, and then clean the valve hole. Even if there are only small particles between the valve seat and the ball, the sealing surface of the valve seat may be damaged.
6. Install the valve into the line. Any end of the valve can be installed at the upstream end. The valve driven by handle can be installed at any position on the pipeline. However, ball valves with gearboxes or pneumatic actuators shall be installed vertically, i.e. on horizontal pipes, with the driving device above the pipes.
7. Install gasket between valve flange and pipeline flange according to pipeline design requirements.
8. The bolts on the flange shall be tightened symmetrically, step by step and evenly.
9. Connect pneumatic pipeline (when pneumatic driver is used).
10. Operate the drive to open and close the ball valve for several times, and it should be flexible without stagnation to confirm its normal operation.
11. Check the sealing performance of flange joint surface between pipeline and ball valve according to pipeline design requirements.

進(jìn)口銅球閥產(chǎn)品簡(jiǎn)介：
