美國進口派克高壓球閥產品參數

美國進口派克高壓球閥在管路中主要用來做切斷、分配和改變介質的流動方向。球閥是近年來被廣泛采用的一種新型閥門，它具有以下優點：
1． 流體阻力小，其阻力系數與同長度的管段相等。
2． 結構簡單、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，在真空系統中也已廣泛使用。
4． 操作方便，開閉迅速，從全開到全關只要旋轉90°，便于遠距離的控制。
5． 維修方便，球閥結構簡單，密封圈一般都是活動的，拆卸更換都比較方便。
6． 在全開或全閉時，球體和閥座的密封面與介質隔離，介質通過時，不會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用。

US imports Parker high-pressure valve in the pipeline is mainly used for cutting, distribution and change the direction of media flow. Ball is a new valve has been widely used in recent years, it has the following advantages:
1. Fluid resistance, the pipe resistance coefficient equal to the same length.
2. Simple structure, small size and light weight.
3. Close and reliable valve sealing surface material widely used plastic, sealing, have been widely used in the vacuum system.
 4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation 90 °, to facilitate remote control.
5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.
6. In the fully open or fully closed, sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface.
7. Wide range of applications, from small to a few millimeters in diameter, large meters, from high vacuum to high pressure can be applied.
