進(jìn)口高壓電動(dòng)截止閥?∕進(jìn)口高溫電動(dòng)截止閥∕美國(guó)電動(dòng)閥門(mén)
誠(chéng)意向您*進(jìn)口高壓電動(dòng)截止閥?廣州施克閥門(mén)有限公司?是國(guó)內(nèi)系列產(chǎn)品的專業(yè)銷售商，專業(yè)銷售各系列如果您有這方面的需求?疑問(wèn)請(qǐng)?：： 孫復(fù)?
原理特征
具有以下優(yōu)點(diǎn)：
1． 流體阻力小，其阻力系數(shù)與同長(zhǎng)度的管路段相等。
2． 結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕。
3． 緊密可靠，目前閘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，閘閥結(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)，閥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(mén)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。 球旋轉(zhuǎn)90度時(shí)，在進(jìn)、出口處應(yīng)全部呈現(xiàn)球面，從而截?cái)嗔鲃?dòng)。
美國(guó)力沃LEO進(jìn)口電動(dòng)截止閥是一種比較新型的閥門(mén)類別，它有著自身結(jié)構(gòu)所*的一些*性，如開(kāi)關(guān)無(wú)摩擦，密封不易磨損，啟閉力矩小。這樣可減小所配執(zhí)行器的規(guī)格。配以多回轉(zhuǎn)電動(dòng)執(zhí)行機(jī)構(gòu)，可實(shí)現(xiàn)對(duì)介質(zhì)的調(diào)節(jié)和嚴(yán)密切斷。
Force Wal-[IK] import electric valve is mainly used in petroleum, chemical, pharmaceutical, fertilizer, electric power and other industries line cut, distribution and change the direction of media flow. In recent years been widely adopted a new valve
Principle characteristics
Has the following advantages:
1. Fluid resistance is small, the drag coefficient with the length equal to the pipe sections.
2. Simple structure, small size, light weight.
3. Strong, reliable, current gate valve sealing surface material widely used plastic, sealing, and has 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 structure, gate valves, seals are generally active, the removal replacement is more convenient.
6. Fully open or fully closed, the valve body and the valve seat sealing surface and the dielectric isolation, through the media, does not cause erosion of the valve sealing surface.
7. A wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied. The ball is rotated 90 degrees, in the import and export at all rendered sphere, thereby cutting off the flow.
Force Wal-LEO import electric valve valve is a relatively new category, it has some of the superiority of their own unique structure, such as the switch without friction, sealing easy to wear, small torque. This can be reduced with the specifications of the actuator. Together with the multi-turn electric actuator, media regulation and strict cut off.
