進口蒸汽電動球閥

蒸汽電動球閥是是工業自動化控制系統中的重要執行機構。電動球閥是根據閥瓣的這種移動形式繞閥桿的軸線作旋轉運動的閥門。閥座通口的變化是與閥瓣行程成正比例關系。主要用于截斷或接通管路中的介質，亦可用于流體的調節與控制，是工業自動化過程控制的一種管道壓元件。蒸汽電動球閥構造簡略，只由少數幾個零件組成，資料耗用��；體積小、重量輕、安裝尺寸小，驅動力矩小, 壓力調節閥，操作簡便、敏捷，只需旋轉90°即可快速啟閉；并且還同時具有良好的流量調節功效和封閉密封特性，在大中口徑、中低壓力的應用范疇，蒸汽電動球閥是主導的閥門情勢。電動球閥處于完整開啟地位時，球體厚度是介質流經閥體時唯一的阻力，因此通過該閥門所發生的壓力降很小，故具有較好的流量把持特征。

進口蒸汽電動球閥優點：

1．由于球閥在啟閉過程中有摩擦性，所以可用于帶懸浮固體顆粒的介質中。流體阻力小，全通徑的球閥基本沒有流阻。

2．結構簡單、體積小、重量輕。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。

3．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，能實現完全密封。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。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。

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。

進口蒸汽電動球閥特點：

1、在閥門全開、全關位置設有鎖定孔，防止非工作人員誤操作。

2、在閥桿下部設置臺階，不至于閥門內壓異常升高脫出閥桿。

3、在球體與閥座間設置耐火密封環，閥座燒損后，仍具有密封作用。

4、開關迅速、啟閉靈活，壽命長，安全可靠。

5、氣動、電動球閥可遠距離集中控制，且能滿足計算機程控之需要。

進口蒸汽電動球閥特征：

1、蒸汽電動球閥配備各種進口電動執行器，高扭力輸出，反應靈敏，能快速實現對球閥的開關或者調節控制；

2、蒸汽電動球閥的電動裝置采用德國先進的電子元件，降低噪音污染；

3、蒸汽電動球閥的電動裝置配高級的防護或者防爆裝置，可適用于高溫，潮濕或者需要防爆的場合。

Inlet steam electric valve

Steam electric ball valve is industrial automation and control systems important actuators. Electric ball is moving around the stem According to this form of valve valve axis for rotary motion. Changes through the mouth of the seat and the valve stroke is directly proportional relationship. Mainly used for cut off or connected line of medium, can be used to adjust and control fluid pressure is a conduit element of industrial automation process control. Steam electric valve structure is simple, consisting of only a few parts, materials consumption province; small size, light weight, small installation size, the drive torque, pressure regulating valve, simple, quick, just rotate 90 ° to quickly opening and closing; and also at the same time has a good flow regulation efficacy and closed sealing characteristics, in medium and large caliber, scope of application of low pressure steam electric ball valves dominant situation. Electric valve is in the full open position, the ball is only the thickness of the medium flowing through the body resistance, so that the valve by the pressure drop occurred in small, it has good flow characteristics dominated.

Inlet steam electric valve advantages:

1. Because there is friction in the valve opening and closing process, it can be used for media with suspended solid particles. Fluid resistance, full bore valve basically no flow resistance.

2. Simple structure, small size and light weight. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied.

3. Compact and reliable, it has two sealing surfaces, and valve sealing surface material widely used in a variety of plastics, sealing, and can be completely sealed. In the vacuum system has also been widely used.

4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface.

5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.

Inlet steam electric valve features:

1, in the valve is fully open, fully closed position with the lock hole to prevent the misuse of non-staff members.

2, in the lower part of the stem set level, within not abnormally elevated pressure valve prolapse stem.

3, setting fire-resistant seal between the ball and valve seat ring, after burning seat, still has a sealing effect.

4, switch quickly, hoist flexible, long life, safe and reliable.
