Under such circumstances, it is necessary to a kind of YE with power-off restoration function, when system AC power has a power failure, can with Rapid reset, system again it is electric after, return to the aperture of original regulation.
The YE with power-off restoration function has two schemes at present：
One kind is spring reset type, and using wind spring stored energy amount, when YE power supply disconnects, the wind spring releases energy valve closing.It has the disadvantage：Consume energy big short life, high cost, to consume the energy always in the course of the work, improves operating cost.
Another kind is electric capacity restoration type YE, and the energy is stored using capacitor charge and discharge, and after YE loses power supply, the energy stored using super capacitor is by valve closing.It has the disadvantage：Electric capacity is that AC power is converted into dc source, is only applicable to direct current generator, and normally only suitable for the small power switch valve such as air door, range of application is limited.
Both the above scheme is all the YE with power-off restoration function, construction differs widely with common YE, manufacturer one of the main divisions of the male role in traditional opera produces two kinds of different YEs, when wishing that the actuator has power-off restoration function using the YE user of usual function, a whole set of YE must be changed, not only cost of idleness but also man-hour had been expended, improvement cost is excessive.
The content of the invention
To solve prior art problem, the present invention provides one kind and can be used for various control systems, and can match alternating current generator can be used as common YE, also be the solution of power-off restoration type YE.
