进口电动调节球阀《进口球阀品牌》德国LOCKE
德国洛克《DE LOCKE》进口电动调节球阀适用于两位切断、调节的场合。球阀与执行机构的连接采用直连方式，电动执行机构内置伺服系统，无须另配伺服放大器，输入4-20mA信号及220VAC电源即可控制运转。电动调节球阀具有连线简单，结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。
电动调节球阀通常用于密封要求严格的场合，除控制气体、液体、蒸汽介质外，还适宜控制污水和含有纤维性杂质的介质，广泛用于石油、化工、冶金、轻工、造纸、电站、制冷等工作领域。电动调节球阀是一种重要的阀类，在石油化工、长输管线等领域有广泛应用。球阀的关闭件是一个带孔的球体（或部分球），球体随阀杆转动，实现阀门的开启或关闭。电动调节球阀旋转90°即可全关全开，与相同规格的闸阀、截止阀比较、球阀体积小、重量轻，便于管道安装。
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.流体阻力小、球阀是所有发类中流体阻力zui小的一种，即使是缩径球阀，其流体阻力也相当小。
2.止推轴承减小阀杆摩擦力矩，可使用阀杆长期操作平衡灵活。
3.阀座密封性能好，采用聚四氟乙烯等材料制成的密封圈，结构易于密封，而且球阀的阀封能力随着介质的压力增大而增大。
4.阀杆密封可靠，由于阀杆只做旋转运动而不是升降运动，阀杆的填料密封不易破坏，且密封能力随着介质的压力增设而增大。
5.由于聚四氟乙烯材料具有良好的自润滑性，与球体的摩擦损失小，帮球阀的使用寿命长。
6.下装式阀杆和阀杆头部凸阶防止阀杆喷出，如果火灾造成阀杆密封破坏，凸阶与阀体间还可以形成金属接触，确保阀杆密封。
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.
