中國(guó)丹佛斯閥門集團(tuán)上海獨(dú)資公司丹富斯球閥(DFQ41F-16P)的工作原理是靠旋轉(zhuǎn)閥芯來(lái)使閥門暢通或閉塞。球閥開(kāi)關(guān)輕便，體積小，可以做成很大口徑，密封可靠，結(jié)構(gòu) 簡(jiǎn)單，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，在各行業(yè)得到廣泛的應(yīng)用。

不銹鋼球閥

不銹鋼球閥和旋塞閥是同屬一個(gè)類型的閥門，只有它的關(guān)閉件是個(gè)球體，球體繞閥體中心線作旋轉(zhuǎn)來(lái)達(dá)到開(kāi)啟、關(guān)閉的一種閥門。

在管路中主要用來(lái)做切斷、分配和改變介質(zhì)的流動(dòng)方向。電動(dòng)球閥是被廣泛采用的一種新型閥門。

優(yōu)點(diǎn)：

1． 流體阻力小，其阻力系數(shù)與同長(zhǎng)度的管段相等。

2． 結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕。

3． 緊密可靠，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(kāi)閉迅速，從全開(kāi)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(jiǎn)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(kāi)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(guò)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。

丹富斯已廣泛應(yīng)用于石油、化工、發(fā)電、造紙、等各部門，以及人們?nèi)粘Ｉ钪小?/span>

Dan fuss ball valve (DFQ41F - 16 p) is to rely on the working principle of rotary valve core to keep the valve open or closed. Ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries.

Stainless steel ball valve

Stainless steel ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve.

Stainless steel ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Ball valve is widely used a new type of valve.

Advantages:

1. The fluid resistance is small, its resistance coefficient with section of equal length.

2. Simple structure, small volume, light weight.

3. Compact and reliable, ball valve sealing surface material widely used plastic, sealing good, also has been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.

7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

Dan fuss stainless steel ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
