進(jìn)口不銹鋼球閥德國洛克廠家強(qiáng)烈推薦

進(jìn)口不銹鋼球閥結(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、開關(guān)迅速、方便,只要閥桿轉(zhuǎn)動90℃,球閥就完成了全開或全關(guān)動作很容易實(shí)現(xiàn)快速啟閉。

3、閥座密封性能好。大多數(shù)球閥的密封圈都采用聚四乙烯等彈性材料制造,軟密封結(jié)構(gòu)易于保證啟封,而且球閥的密封力隨著介質(zhì)壓力的增高而增大。

4、閥桿密封可靠。球閥啟閉時閥桿只作旋轉(zhuǎn)運(yùn)動而不作升降運(yùn)動,閥桿的填料密封不易破壞,且閥桿倒密封的密封力隨著介質(zhì)壓力的增高而增大。

5、由于聚四F乙烯等材料具有良好的自潤滑性,與球體的摩擦損小,故球閥的使用壽命長。

6、可配置氣動、電動、液動等多種驅(qū)動機(jī)構(gòu),實(shí)現(xiàn)遠(yuǎn)距離控制和自動化操作。

7、閥體內(nèi)通道平整光滑,可以輸送粘性流體、漿液以及固體顆粒。

8、安裝簡便,能以任意方向安裝于管道中的任意部位。

Structural features of imported stainless steel ball valve:

1. The fluid resistance is small. The ball valve is one of the smallest in all kinds of valves. Even if it is a reduced diameter ball valve, its fluid resistance is quite small.

2. As long as the valve rod rotates 90 ℃, the ball valve will be fully opened or closed, and it is easy to open and close quickly.

3. The valve seat has good sealing performance. The sealing ring of most ball valves is made of elastic materials such as poly (tetra). The soft sealing structure is easy to ensure unsealing, and the sealing force of ball valve increases with the increase of medium pressure.

4. The valve rod is sealed reliably. When the ball valve is opened and closed, the valve rod only rotates and does not move up and down. The packing seal of the valve rod is not easy to be damaged, and the sealing force of the valve stem back sealing increases with the increase of the medium pressure.

5. Because PTFE and other materials have good self-lubricating property and small friction loss with the ball, the service life of ball valve is long.

6. Pneumatic, electric, hydraulic and other driving mechanisms can be configured to realize remote control and automatic operation.

7. The channel inside the valve body is flat and smooth, which can transport viscous fluid, slurry and solid particles.

8. It is easy to install and can be installed in any part of the pipeline in any direction.

進(jìn)口不銹鋼球閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口不銹鋼球閥分為全通徑及縮徑兩個系列,以滿足不同工況的需要。全通徑球閥的通道內(nèi)徑與管線內(nèi)徑一致,流體阻力最小,并便于管道清掃。而縮徑系列球閥的重量只有相同口徑全通徑球閥的70%左右,能有效的降低成本及價格,而其流體阻力只有相同口徑截止閥的1/7左右,故縮徑球閥在國內(nèi)得到了較廣泛的使用。
