Energy-saving two-speed splash sprinkler

Abstract

The invention relates to an energy-saving two-speed spray nozzle comprising an inflow tube, a support and a spray disc. A fixing shaft of the spray disc is disposed in the center of a bottom beam of the support. The spray disc is mounted on the fixing shaft through a bearing shaft; a nozzle body is connected to the inner bottom of the inflow tube in a threaded manner; a spiral structural device which divides single flow entering the inflow tube into multiple rotary flows is mounted in the inflow tube; the spiral structural device is located at the upper end of the nozzle body; the center of the spray disc is provided with a conical table integrated to the spray disc; the outside of the conical table is evenly provided with a plurality of spray strips; a plurality of thin slots are provided in the spray disc between the conical table and blades; the part, close to the bearing shaft, of the back of the spray disc is concaved; two nylon bearings with one separately above the other are disposed between the bearing shaft and the fixing shaft. The energy-saving two-speed spray nozzle sprays water in a good form, sprays more evenly, is better in structural tightness, helps save energy of a cooling tower and improve cooling effect and is especially suitable for high-temperature towers, large towers, power plants and the like.

Description

technical field [0001] The invention relates to a splashing device, in particular to an energy-saving double-speed splashing nozzle. Background technique [0002] The splashing device is installed on the water distribution pipe of the cooling tower to spray hot water for cooling. The effect of the splashing device directly affects the cooling effect, but the currently installed splashing device is rotated by the direct flushing water flowing out of the connecting pipe. When the water pressure is low, the rotary splashing device rotates slowly or stops, and the splashing dish of the rotary splashing device is lubricated by the disc shaft water. There is no bearing between the disc shafts, the resistance is large, the wear is fast, the imbalance is short, and the useful cycle is short. [0003] The patent document with the patent application number 201420235752.1 discloses a new type of internal rotation energy-saving rotary splashing device, which is composed of a support fra...
