Abstract
The present invention relates to an automatic work type showering valve controlled magnetically, which is composed of a pilot valve controlled magnetically and a showering valve, wherein a magnetic ring, a magnetic core, a temperature shape memory alloy, a small piston component and a large piston component are formed in the pilot valve controlled magnetically. When a fire occurs on a site, the temperature shape memory alloy generates deformation, and the pilot valve controlled magnetically is pushed to be opened. After the pilot valve is opened, the upper end and the lower end of a valve core of the showering valve form pressure difference, and thus, the showering valve is rapidly opened. When the fire is extinguished, the environment temperature returns to the normal temperature, and the memory alloy returns to the original state. Thus, the pilot valve controlled magnetically is closed, and as a result, the showering valve is closed and restored to the standby state.
