电磁阀和电动阀的区别 作者:aufine2009

1.开关形式:
    电磁阀通过线圈驱动,只能开或关 ,开关时动作时间短。
    电动阀的驱动一般是用电机,开或关动作完成需要一定的时间模拟量的,可以做调节.
    2.工作性质:
    电磁阀一般流通系数很小,而且工作压力差很小。比如一般25口径的电磁阀门流通系数比15口径的电动球阀小很多。电磁阀的驱动是通过电磁线圈,比较容易被电压冲击损坏。相当于开关的作用,就是开和关2个作用。
    电动阀的驱动一般是用电机,比较耐电压冲击。电磁阀是快开和快关的,一般用在小流量和小压力,要求开关频率大的地方电动阀反之。电动阀阀的开度可以控制,状态有开、关、半开半关,可以控制管道中介质的流量而电磁阀达不到这个要求。
    电磁阀一般断电可以复位,电动阀要这样的功能需要加复位装置。

    3.适用工艺:
    电磁阀适合一些特殊地工艺要求,比如泄漏、流体介质特殊等,价格较贵。
    电动阀一般用于调节,也有开关量的,比如:风机盘管末端。

1,. Switch the form of:
     Driven through the solenoid valve coil, only on or off, the switch moves a short time.
     Valve electric drive motor is generally used, on or off action will take some time to complete simulation of the volume, you can do conditioning.
     2. The nature of the work:
     Solenoid valve flow coefficient generally small, and the work of a very small pressure difference. For example, the general diameter of the solenoid valve 25, the flow coefficient of the electric 15-caliber ball valve is much smaller. Solenoid valve driven by electromagnetic coils, voltage shocks have been relatively easy to damage. Equivalent to the role switch is OFF the role of two.
     Valve electric drive motor is generally used to compare the impact of voltage. Solenoid valve is open and fast speed, and tends to be used in a small volume and small pressure to the switching frequency of the local electric valve big contrast. Electric valve to control the opening, the state has to open, clearance, half-open half-clearance, you can control the flow of media channels and the solenoid valve able to meet this requirement.
     Solenoid valve can be reset general power, the electric valve to the function of such devices need to reset.
 

     3. The application process:
     Solenoid valve and process for some special requirements, such as leakage of fluid medium, such as special, more expensive prices.
     Electric valve for regulating the general as well as the volume switch, such as: fan-coil terminal.
