進(jìn)口電動(dòng)螺紋球閥的工作原理是靠旋轉(zhuǎn)閥戀來使閥門暢通或閉塞。電動(dòng)球閥開關(guān)輕便，體積小，可以做成很大口徑，密封可靠，結(jié)構(gòu)簡單，維修方便，密封面與球面常在閉合狀態(tài)，不易被介質(zhì)沖蝕，在各行業(yè)得到廣泛的應(yīng)用。The working principle of the imported electric ball valve is to make the valve unblocked or blocked by the rotating valve. The electric ball valve switch is light and small, and can be made into large caliber. It has reliable sealing, simple structure and convenient maintenance. The sealing surface and sphere are often closed, and are not easily eroded by the medium, so they are widely applied in various industries.
進(jìn)口電動(dòng)球閥和旋塞閥是同屬一個(gè)類型的閥門，只有它的關(guān)閉件是個(gè)球體，球體繞閥體中心線作旋轉(zhuǎn)來達(dá)到開啟、關(guān)閉的一種閥門。
電動(dòng)球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動(dòng)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(yōu)點(diǎn)：The imported electric ball valves and plug valves belong to one type of valves. Only its closing member is a sphere, and the sphere is rotated around the center line of the valve to achieve a valve opening and closing.
The flow direction ball valve in the pipeline is mainly used for cutting, distribution and change of medium. Ball valve is a new type of valve which has been widely used in recent years. It has the following advantages:
1．流體阻力小，其阻力系數(shù)與同長度的管段相等。
2．結(jié)構(gòu)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(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。
5．維修方便，球閥結(jié)構(gòu)簡單，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。
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。
1. the fluid resistance is small, and the resistance coefficient is equal to the tube length of the same length.
2. has the advantages of simple structure, small volume, light weight.
3. closely reliable, current valve sealing surface material widely used plastic, good sealing in the vacuum system has also been widely used.
4. convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote
5. ball valve has the advantages of simple structure, convenient maintenance, seals are generally activities, removal of the replacement is more convenient.
6. in the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation medium through, will not cause erosion of the valve sealing surface.
7. wide range of applications, from small diameter to a few millimeters high, a few meters from the high vacuum high pressure can be applied.
