进口电动球阀,德国莱克LIK品牌
德国莱克LIK品牌,进口电动球阀是是工业自动化控制系统中的重要执行机构。电动球阀是根据阀瓣的这种移动形式绕阀杆的轴线作旋转运动的阀门。阀座通口的变化是与阀瓣行程成正比例关系。主要用于截断或接通管路中的介质，亦可用于流体的调节与控制，是工业自动化过程控制的一种管道压元件。
进口电动球阀（英文名：Electronic Ball Valve）由电动执行机构和球阀共同构成电动球阀。
是工业自动化过程控制的一种管道压元件，通常用于管道介质的远程开、关（接通、切断介质）控制。电动球阀标准DIN《阀门术语》中定义为：启闭件（球体）由阀杆带动，并绕阀杆的轴线作旋转运动的阀门。主要用于截断或接通管路中的介质，亦可用于流体的调节与控制，其中硬密封V型球阀其V型球芯与堆焊硬质合金的金属阀座之间具有很强的剪切力，特别适用于含纤维、微小固体颗料等介质。电动球阀分为电动法兰球阀，电动对夹球阀，电动焊接球阀，电动丝扣球阀。根据密封形式还分为软密封电动球阀，硬密封电动球阀。
选择进口电动球阀的依据是什么
电动球阀选择的依据是什么?是控制元件，在流体管道系统的应用中，是非常广泛的，它的用途也非常多，对控制流量、压力、回流等等，都有 非常好的效果。由于电动球阀质量的好坏，对管道的安全性，有很大的影响，所以在选择电动球阀的时候，一定要按照一定的步骤和依据进行 挑选。 电动球阀选择的依据是什么？1、明确自己公司的管道的口径，知道需要选择什么样口径和连接方式的电动球阀。2、根据管道的需要，先 确定电动球阀的一些常见参数，比如排放能力、可以允许的流阻、阀座孔的通径大小 等等，这些参数如果没有选对，电动球阀控制流量的效果 ，就会大打折扣。3、根据管道的工作温度，选择合适的材质，当然，管道的工作压力，也是要考虑在内 的。 另外，还要提醒的是，不要急着去挑选产品，要先了解现在流行的电动球阀产 品有哪些、性能如何，而了解这些的方法，就是联系多 家电动球阀的生产企业，让他们提供产品目录、样式等等，货比三家，才能选择到性价比最高的产品。

What is the basis for the choice of electric valve? Is the control element, in the application of fluid pipeline system, is a very broad, its use is very much also, to control the flow, pressure, flow and so on, have very good results. Because the electric ball valve quality, safety of pipeline, have a great impact, so in the choice of electric valve, must be selected in accordance with the procedures and according to certain. What is the basis for the choice of electric valve? 1, clear the pipeline his company's caliber, know electric valve need to choose what kind of caliber and connection method. 2, according to the pipeline needs, to identify some common parameters of electric ball valve, such as discharge capacity, can allow the flow resistance, the valve seat hole diameter size and so on, these parameters if not elected to the electric ball valve, flow control effect, will be greatly reduced. 3, according to the working temperature of the pipeline, selecting suitable material, of course, the operating pressure of the pipeline, but also take into account. In addition, but also to remind is, do not rush to the selection of products, we should first understand the electric ball valve products popular now what, how performance, and know the best method, is much home electric ball valve manufacturing enterprises, allowing them to provide product catalog, style and so on, goods than three, we can choose to the highest cost- effective products.
进口电动球阀有哪几种限位
原文：
电动阀门是指由电机驱动控制的阀门，常见的电动阀门有：电动球阀、电动蝶阀、电动闸阀等。
电动阀门限位分为机械限位和电气限位两种。
电动阀门机械限位是指：电动阀门工作时，限位机械部件安装在电机传动轴上，电机在0-90度旋转时，限位块随着转动，从而实现阀门的开关控制。此机械限位可以由调节螺栓调 整其开度范围，一般在+/-10度左右的调节。机械限位可以防止工作人员误操作时引起的电机烧坏，从而达到保证电动阀门正常工作的目的。
电动阀门电气限位是指：通过控制电动阀门的电源通断，来实现阀门的开关。当电机在0-90度旋转到位时，传动轴凸轮挤压内置微动开关来控制电机电源的开通或切断以实现阀门 的开关功能。
电动阀门的机械限位和电气限位相辅相成，配合使用能更精准的控制阀门的开关，达到管道介质流量的控制。但在实际使用过程中，应同时使机械限位和电气限位协调动作，否则
容易引起电机工作故障。 电动球阀有哪几种限位。

Electric valve is driven and controlled by electric valve, electric valve common are: electric valve, electric butterfly valve, electric valve etc.. Electric valve limit is divided into the mechanical limit and electrical limit two. Electric valve mechanical limit refers to: electric valve, limit mechanical components are mounted on a motor shaft, motor in the 0-90 rotating, the limiting block with the rotation, so as to realize the switch of the valve control. The mechanical limit by adjusting bolt to adjust the opening range, about +/-10 degrees regulation general. Mechanical limit can prevent the motor from being burnt staff misoperation caused, so as to ensure the normal work of the purpose of electric valve. Electric valve electric limiting means: through the power control electric valve, to achieve the valve switch. When the motor in the 0-90 rotating in place, drive shaft, cam extrusion built-in micro switch to control the motor power on and off to realize the switching function of the valve. Electric valve mechanical limit and electrical spacing are complementary, matched to switch control valve more accurate, to achieve control of medium flow pipe. But in practice, should also make the mechanical limit and electrical limit coordinated action, otherwise easily lead to motor fault.
