| 详细介绍： 进口蒸汽电动球阀
蒸汽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。蒸汽电动球阀构造简略，只由少数几个零件组成，资料耗用省；体积小、重量轻、安装尺寸小，驱动力矩小, 压力调节阀，操作简便、敏捷，只需旋转90°即可快速启闭；并且还同时具有良好的流量调节功效和封闭密封特性，在大中口径、中低压力的应用范畴，蒸汽电动球阀是主导的阀门情势。电动球阀处于完整开启地位时，球体厚度是介质流经阀体时唯一的阻力，因此通过该阀门所发生的压力降很小，故具有较好的流量把持特征。
进口蒸汽电动球阀优点：
1．由于球阀在启闭过程中有摩擦性，所以可用于带悬浮固体颗粒的介质中。流体阻力小，全通径的球阀基本没有流阻。
2．结构简单、体积小、重量轻。适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。
3．紧密可靠，它有两个密封面，而且球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。在真空系统中也已广泛使用。
4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。
5．维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。
进口蒸汽电动球阀特点：
1、在阀门全开、全关位置设有锁定孔，防止非工作人员误操作。
2、在阀杆下部设置台阶，不至于阀门内压异常升高脱出阀杆。
3、在球体与阀座间设置耐火密封环，阀座烧损后，仍具有密封作用。
4、开关迅速、启闭灵活，寿命长，安全可靠。
5、气动、电动球阀可远距离集中控制，且能满足计算机程控之需要。
进口蒸汽电动球阀特征：
1、蒸汽电动球阀配备各种进口电动执行器，高扭力输出，反应灵敏，能快速实现对球阀的开关或者调节控制；
2、蒸汽电动球阀的电动装置采用德国先进的电子元件，降低噪音污染；
3、蒸汽电动球阀的电动装置配高级的防护或者防爆装置，可适用于高温，潮湿或者需要防爆的场合。

Inlet steam electric valve
Steam electric ball valve is industrial automation and control systems important actuators. Electric ball is moving around the stem According to this form of valve valve axis for rotary motion. Changes through the mouth of the seat and the valve stroke is directly proportional relationship. Mainly used for cut off or connected line of medium, can be used to adjust and control fluid pressure is a conduit element of industrial automation process control. Steam electric valve structure is simple, consisting of only a few parts, materials consumption province; small size, light weight, small installation size, the drive torque, pressure regulating valve, simple, quick, just rotate 90 ° to quickly opening and closing; and also at the same time has a good flow regulation efficacy and closed sealing characteristics, in medium and large caliber, scope of application of low pressure steam electric ball valves dominant situation. Electric valve is in the full open position, the ball is only the thickness of the medium flowing through the body resistance, so that the valve by the pressure drop occurred in small, it has good flow characteristics dominated.
Inlet steam electric valve advantages:
1. Because there is friction in the valve opening and closing process, it can be used for media with suspended solid particles. Fluid resistance, full bore valve basically no flow resistance.
2. Simple structure, small size and light weight. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied.
3. Compact and reliable, it has two sealing surfaces, and valve sealing surface material widely used in a variety of plastics, sealing, and can be completely sealed. In the vacuum system has also been widely used.
4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface.
5. Easy maintenance, simple ball valve, seals are generally activities, the removal replacement is more convenient.
Inlet steam electric valve features:
1, in the valve is fully open, fully closed position with the lock hole to prevent the misuse of non-staff members.
2, in the lower part of the stem set level, within not abnormally elevated pressure valve prolapse stem.
3, setting fire-resistant seal between the ball and valve seat ring, after burning seat, still has a sealing effect.
4, switch quickly, hoist flexible, long life, safe and reliable.
5, pneumatic, electric valve can be remote centralized control, and can meet the needs of program-controlled computer.
