摘要： A frame-type sprinkler head for dispensing fire extinguishing liquid. The sprinkler head includes a frame having a conducting hole therein through which fire extinguishing liquid may flow. The sprinkler head includes a valve body disposed adjacent to the conducting hole for blocking the conducting hole. The sprinkler head including a packing affixed to the valve body to prevent separation of the packing and the valve body. The packing is disposed between the conducting hole and the valve body for preventing leakage of the extinguishing liquid past the valve body. The sprinkler head includes a band-like protrusion extending from an edge of the packing. The band-like protrusion is engaged with an engagement portion provided on the frame for causing pivoting movement of said valve body and for preventing lodgement.
