進(jìn)口蒸汽電動(dòng)球閥

蒸汽電動(dòng)球閥是是工業(yè)自動(dòng)化控制系統(tǒng)中的重要執(zhí)行機(jī)構(gòu)。電動(dòng)球閥是根據(jù)閥瓣的這種移動(dòng)形式繞閥桿的軸線作旋轉(zhuǎn)運(yùn)動(dòng)的閥門。閥座通口的變化是與閥瓣行程成正比例關(guān)系。主要用于截?cái)嗷蚪油ü苈分械慕橘|(zhì)，亦可用于流體的調(diào)節(jié)與控制，是工業(yè)自動(dòng)化過程控制的一種管道壓元件。蒸汽電動(dòng)球閥構(gòu)造簡(jiǎn)略，只由少數(shù)幾個(gè)零件組成，資料耗用省；體積小、重量輕、安裝尺寸小，驅(qū)動(dòng)力矩小, 壓力調(diào)節(jié)閥，操作簡(jiǎn)便、敏捷，只需旋轉(zhuǎn)90°即可快速啟閉；并且還同時(shí)具有良好的流量調(diào)節(jié)功效和封閉密封特性，在大中口徑、中低壓力的應(yīng)用范疇，蒸汽電動(dòng)球閥是主導(dǎo)的閥門情勢(shì)。電動(dòng)球閥處于完整開啟地位時(shí)，球體厚度是介質(zhì)流經(jīng)閥體時(shí)唯一的阻力，因此通過該閥門所發(fā)生的壓力降很小，故具有較好的流量把持特征。

進(jìn)口蒸汽電動(dòng)球閥優(yōu)點(diǎn)：

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(zhì)中。流體阻力小，全通徑的球閥基本沒有流阻。

2．結(jié)構(gòu)簡(jiǎn)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(yīng)用。

3．緊密可靠，它有兩個(gè)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(shí)現(xiàn)完全密封。在真空系統(tǒng)中也已廣泛使用。

4．操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90°，便于遠(yuǎn)距離的控制。在全開或全閉時(shí)，球體和閥座的密封面與介質(zhì)隔離，介質(zhì)通過時(shí)，不會(huì)引起閥門密封面的侵蝕。

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。

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.
