Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with examples and drawings pair
The utility model embodiment is described in further detail.
As shown in Figure 1, be crossflow cooling tower watering device structure, including water inlet 1, broadcast tank lid 2, high water level broadcasts water tank
3 and variable-flow spray head 4；The water inlet 1, which is mounted on, broadcasts 2 top of tank lid, and fixes with tank lid is broadcast；It is described to broadcast tank lid
2, which are fixed on high water level, broadcasts 3 top of water tank, to prevent the entrance of sundries；The high water level broadcast bottom in water tank 3 be provided with it is more
A variable-flow spray head 4, for collecting hot water and spraying；The variable-flow spray head 4 be provided with it is multiple, and including water chamber 404
With pressurization current limiter 403, the water chamber includes inside inlet opening 601 and outside inlet opening 602, and the pressurization current limiter is set to
It in inside inlet opening among water chamber, and is pressurized current limiter and is set as internal diameter adjustable pressure increasing current limiter, internal diameter difference is adjustable
For D1、D2…Di(as shown in Figure 4).
Above-mentioned high water level, which is broadcast, is provided with cooling tower filler area below water tank.
As shown in Figures 2 and 3, above-mentioned variable-flow spray head further include: upper cover 401, small flow baffle 402 and shower 405,
The upper cover is set to the top of small flow baffle, and connect with water chamber；The shower is set to the lower section of water chamber and and water chamber
Connection；Inlet opening includes multiple on the outside of the water chamber, and is uniformly distributed.(as shown in Figure 7).
Above-mentioned variable-flow spray head 4 is uniformly distributed in the two sides of water inlet 1, and water inlet diameter DWater inletLess than left and right sides
