氣動球閥與其它種類閥門相比優勢

來源:http://m.lzpazx.cn/ 日期:2023-08-12 發布人:admin
止推軸承減小閥桿摩擦力矩,可使閥桿操作平穩靈活。
The thrust bearing reduces the friction torque of the valve stem, which can ensure smooth and flexible operation of the valve stem.
防靜電功能:在球體閥桿閥體之間設置彈簧,能將開關過程中產生的靜電導出。
Anti static function: A spring is installed between the ball valve stem and valve body, which can export the static electricity generated during the switching process.
由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的摩擦損失小,故氣動球閥的使用壽命長。
Due to the good self-lubrication of materials such as polytetrafluoroethylene and low friction loss with the ball, the service life of pneumatic ball valves is long.
流體阻力小:氣動球閥是所有閥門分類中流體阻力較小的一種,即使是縮徑氣動球閥,其流體阻力也相當小。
Low fluid resistance: Pneumatic ball valves have the lowest fluid resistance among all valve classifications, even for reduced diameter pneumatic ball valves, their fluid resistance is relatively small.
閥桿密封可靠:由于閥桿只作轉動運動而不做升降運動,閥桿的填料密封不易破壞,且密封能力隨著介質壓力的增高而增大。
Reliable valve stem sealing: Due to the fact that the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases with the increase of medium pressure.
閥座密封性能好:采用聚四氟乙烯等彈性材料制成的密封圈,結構易于密封,而且氣動球閥的閥封能力隨著介質壓力的增高而增大。

Good sealing performance of the valve seat: The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal in structure, and the sealing capacity of the pneumatic ball valve increases with the increase of medium pressure.
流體阻力小,全通徑的球閥基本沒有流阻。
The fluid resistance is small, and the full bore ball valve has almost no flow resistance.
結構簡單體積小重量輕。
Simple structure, small size, light weight.
緊密可靠。它有兩個密封面,而且球閥的密封面材料廣泛使用各種塑料,密封性好,能實現密封。在真空系統中也已廣泛使用。
Tight and reliable. It has two sealing surfaces, and the sealing surface material of the ball valve is widely used with various plastics, which has good sealing performance and can achieve sealing. It has also been widely used in vacuum systems.
操作方便,開閉迅速, 球閥 從全開到全關只要旋轉90°,便于遠距離的控制。
Easy to operate, quick to open and close, ball valve can rotate 90 ° from full open to full close, making it easy to control from a long distance.
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。
Convenient maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement more convenient.
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。
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
適用范圍廣,通徑從小到幾毫米,大到幾米,從高真空高壓力都可應用。
It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
由于球閥在啟閉過程中有擦拭性,所以可用于帶懸浮固體顆粒的介質中。
Due to its wiping properties during the opening and closing process, ball valves can be used in media with suspended solid particles.
加工精度高,造價昂貴,高溫中不宜使用,如管道內有雜質,容易被雜質堵塞,導致閥門無法打開。
High processing accuracy, high cost, and unsuitable for use in high temperatures. If there are impurities in the pipeline, it is easy to be blocked by impurities, resulting in the valve being unable to open.
