進口電動調節球閥《進口球閥品牌》德國LOCKE
德國洛克《DE LOCKE》進口電動調節球閥適用于兩位切斷、調節的場合。球閥與執行機構的連接采用直連方式，電動執行機構內置伺服系統，無須另配伺服放大器，輸入4-20mA信號及220VAC電源即可控制運轉。電動調節球閥具有連線簡單，結構緊湊、尺寸小、重量輕、阻力小、動作穩定可靠等優點。
電動調節球閥通常用于密封要求嚴格的場合，除控制氣體、液體、蒸汽介質外，還適宜控制污水和含有纖維性雜質的介質，廣泛用于石油、化工、冶金、輕工、造紙、電站、制冷等工作領域。電動調節球閥是一種重要的閥類，在石油化工、長輸管線等領域有廣泛應用。球閥的關閉件是一個帶孔的球體（或部分球），球體隨閥桿轉動，實現閥門的開啟或關閉。電動調節球閥旋轉90°即可全關全開，與相同規格的閘閥、截止閥比較、球閥體積小、重量輕，便于管道安裝。
De Locke imported electric regulating ball valve is suitable for two position cut-off and regulating occasions. The ball valve and the actuator are connected in direct connection. The electric actuator has a built-in servo system. Without additional servo amplifier, the operation can be controlled by inputting 4-20mA signal and 220VAC power supply. The electric regulating ball valve has the advantages of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action, etc.
Electric regulating ball valve is usually used in the occasions with strict sealing requirements. In addition to controlling gas, liquid and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. It is widely used in petroleum, chemical industry, metallurgy, light industry, paper making, power station, refrigeration and other work fields. Electric regulating ball valve is an important valve, which is widely used in petrochemical, long-distance pipeline and other fields. The closing part of the ball valve is a ball (or part of the ball) with holes. The ball rotates with the valve rod to open or close the valve. The electric regulating ball valve can be fully closed and fully opened by turning 90 °. Compared with the gate valve and globe valve of the same specification, the ball valve is small in volume and light in weight, which is convenient for pipeline installation.
1.流體阻力小、球閥是所有發類中流體阻力zui小的一種，即使是縮徑球閥，其流體阻力也相當小。
2.止推軸承減小閥桿摩擦力矩，可使用閥桿長期操作平衡靈活。
3.閥座密封性能好，采用聚四氟乙烯等材料制成的密封圈，結構易于密封，而且球閥的閥封能力隨著介質的壓力增大而增大。
4.閥桿密封可靠，由于閥桿只做旋轉運動而不是升降運動，閥桿的填料密封不易破壞，且密封能力隨著介質的壓力增設而增大。
5.由于聚四氟乙烯材料具有良好的自潤滑性，與球體的摩擦損失小，幫球閥的使用壽命長。
6.下裝式閥桿和閥桿頭部凸階防止閥桿噴出，如果火災造成閥桿密封破壞，凸階與閥體間還可以形成金屬接觸，確保閥桿密封。
1. The fluid resistance is small, and ball valve is the one with the least fluid resistance among all kinds of engines. Even for the reduced diameter ball valve, its fluid resistance is quite small.
2. The thrust bearing reduces the friction torque of the valve rod, and the valve rod can be used for long-term operation and balance flexibly.
3. The sealing performance of the valve seat is good. The sealing ring made of polytetrafluoroethylene and other materials is easy to seal, and the sealing capacity of the ball valve increases with the pressure of the medium.
4. The valve rod seal is reliable. Because the valve rod only rotates rather than rises and falls, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.
5. Due to the good self-lubricating property of polytetrafluoroethylene material, the friction loss with the ball is small, and the service life of the ball valve is long.
6. The bottom mounted valve rod and the convex step at the head of the valve rod prevent the valve rod from ejecting. If the fire causes damage to the valve rod seal, metal contact can also be formed between the convex step and the valve body to ensure the valve rod seal.
