Detailed Description

This embodiment one kind prevents connecting piece that falls water combines fig. 1 and fig. 2, including outer tube 1 and flabellum 2, establishes solid shutoff piece in the outer tube 1, and the shutoff piece includes inner tube 11 and air flue 3, is provided with pivot 12 on the inner tube 11, and flabellum 2 is installed in the air flue 3 top through pivot 12 slope, falls to the horizontality when flabellum 2 atress, can cover on air flue 3 this moment completely.

According to the scheme, a blocking piece with a solid structure is arranged in an outer pipe 1, and an air passage 3 is arranged on the blocking piece for air flow to pass through; the air duct 3 is provided with the fan blade 2 in a matching way, the fan blade 2 is suspended above the air duct 3 in an inclined state as shown in figures 1, 2, 4 and 6 in a normal state, and at the moment, air flow enters the air duct 3 from top to bottom through the upper part of the fan blade 2 and is output through the air duct 3 in a mode shown by a dotted arrow in figure 5; when water drops fall, the falling water drops force the fan blades 2 to fall and cover the air passages 3, at the moment, the air passages 3 and the inner pipe 11 form a completely blocked plugging piece structure, the fan blades 2 are blocked up and down, and water flow is prevented from entering a pipeline of the next link.
