Referring to fig. 2, the position limiting member 6 includes a plurality of position limiting rods 61 arranged around the central axis of the main water pipe 1, and the position limiting rods 61 are horizontally and fixedly connected to the inner wall of the main water pipe 1. One end of the limiting rod 61 facing the center of the main water pipe 1 is positioned on a sliding path of the ball plug 5 facing the water outlet of the auxiliary water pipe 2, so as to limit the sliding of the ball plug 5 facing the water outlet.

At normal temperature, the temperature-sensitive limiting piece 3 limits the auxiliary water pipe 2 to slide relative to the main water pipe 1, and the ball plug 5 blocks the water inlet of the auxiliary water pipe 2, so that when water flows downwards from the main water pipe 1, the water pressure can make the ball plug 5 tightly fit with the water inlet of the auxiliary water pipe 2, and water in the main water pipe 1 cannot flow into the auxiliary water pipe 2. When a fire disaster happens, the temperature rises to the reaction temperature of the temperature-sensitive limiting part 3, the temperature-sensitive limiting part 3 is melted, the auxiliary water pipe 2 slides relative to the main water pipe 1, the limiting rod 61 limits the ball plug 5 to slide towards the water outlet, the ball plug 5 is separated from the opening edge of the auxiliary water pipe 2, and water flow can flow into the auxiliary water pipe 2 through the gap between the limiting rods 61 to spray and extinguish the fire.
