Abstract
The utility model provides a natural gravity basin-type water distribution nozzle, which prevents a petal-shaped plate from inclining and deforming and comprises a column-shaped main body pipe, a guide pipe extending into the main body pipe and the petal-shaped plate fixedly connected with the lower part of the main body pipe. The top end of the column-shaped main body pipe is provided with a mainring flange. The main body pipe, the guide pipe and the petal-shaped plate are coaxial. The petal-shaped plate is fixedly connected with the lower part of the main body pipe through more than two connecting ribs. The connecting ribs are evenly distributed at the circumferential direction the axes of which is the axes of the guide pipe. Because the petal-shaped plate is fixedly connected with thelower part of the main body pipe through more than two connecting ribs and the connecting ribs are evenly distributed at the circumferential direction the axes of which is the axes of the guide pipe,the petal-shaped plate has balanced stress, does not incline or deform and has good water distribution uniformity.
Description
Technical field
The utility model relates to a kind of square cross flow cooling tower natural gravity pond formula water-distribution nozzle that is used for.
Background technology
Present square cross flow cooling tower water distribution manner generally is adopted as natural gravity pond cellular type water distribution and natural gravity pond formula shower nozzle water distribution.There is following problem respectively in this two water distribution manner:
1, natural gravity pond cellular type water distribution.Because water distributing pore aperture, hole count are restricted, particularly the water distributing pore aperture is restricted, and water distributing pore stops up easily, needs often to sweep cleaning in the basin of pond, and water distribution is inhomogeneous, and the part water column reception basin that directly falls influences thermal performance (cooling effect).
2, natural gravity pond formula shower nozzle water distribution.The natural gravity pond formula water-distribution nozzle that adopts carries out water distribution.This shower nozzle comprises that the upper end has the cylinder-shaped body pipe of a main ring flange, extend into mozzle in the main body pipe, is fixedly connected on the petal disc of main body pipe bottom; Main body pipe, mozzle, petal disc three coaxial line.Because of the dowel between its main body pipe and the petal disc has only one, the easy inclination and distortion of petal disc has influenced uniformity of water distribution, influences outward appearance again, the inhomogeneous thermal performance efficient (cooling effectiveness) that can influence again of water distribution.In addition, mozzle is to be slidingly connected in the main body pipe, and the shower nozzle mozzle comes off easily when dismounting and change, cleaning.
The utility model content
The purpose of this utility model provides a kind of natural gravity pond formula water-distribution nozzle that guarantees that petal disc can inclination and distortion.
This used for cooling tower natural gravity pond formula water-distribution nozzle comprises that the upper end has the cylinder-shaped body pipe of a main ring flange, extend into mozzle in the main body pipe, is fixedly connected on the petal disc of main body pipe bottom; Main body pipe, mozzle, petal disc three coaxial line, petal disc is fixedly connected on main body pipe bottom by two above dowels, and it is the circumferential direction of axis that dowel is distributed on the mozzle axis.
Because petal disc is fixedly connected on main body pipe bottom by two above dowels, it is the circumferential direction of axis that dowel is distributed on the mozzle axis.Petal disc stress balance can inclination and distortion, and uniformity of water distribution is good.
Best two dowel lower ends overlap, and are connected the center of petal disc jointly; Article two, the dowel upper end relatively is connected on the tube wall of main body pipe.Preferably, the dowel cross section becomes flat ellipse taper.
Natural gravity pond formula water-distribution nozzle for above-mentioned has the taper draw-in groove on main ring flange, the upper end of mozzle has a secondary ring flange, and secondary ring flange embeds and is used to limit in the mobile vertically taper draw-in groove of secondary ring flange.Like this, dismounting and change, when cleaning during shower nozzle mozzle can not break away from the main body pipe.
For above-mentioned natural gravity pond formula water-distribution nozzle, the direction that is parallel to its axis on the external cylindrical surface of main body pipe is provided with reinforcement, makes main body Guan Buhui distortion.
For above-mentioned natural gravity pond formula water-distribution nozzle, the external cylindrical surface of main body pipe is provided with helicoid and the resilient fin that tilts with its axis.By resilient fin, the external cylindrical surface of main body pipe can be screwed in the installing hole on the cooling tower; The main body pipe can not be out of shape yet simultaneously.
For above-mentioned natural gravity pond formula water-distribution nozzle, the mozzle external cylindrical surface is provided with reinforcement.

The specific embodiment
Illustrated used for cooling tower natural gravity pond formula water-distribution nozzle comprises that the upper end has the cylinder-shaped body pipe 2 of a main ring flange 1, extend into mozzle 3 in the main body pipe, is fixedly connected on the petal disc 4 of main body pipe bottom.Main body pipe, mozzle, petal disc three coaxial line.Have taper draw-in groove 6 on main ring flange 1, the upper end of mozzle 3 has a secondary ring flange 7, and secondary ring flange 7 embeds and is used to limit in the mobile vertically taper draw-in groove 6 of secondary ring flange.The direction that is parallel to its axis on the external cylindrical surface of main body pipe 2 is provided with two reinforcements 8.The external cylindrical surface of main body pipe is provided with helicoid and the resilient fin 9 that tilts with its axis.The mozzle external cylindrical surface is provided with reinforcement 10.
Article two, dowel 5 lower ends overlap, and are connected the center of petal disc jointly; Article two, the dowel upper end relatively is connected on the tube wall of main body pipe 2.The cross section becomes two dowels 5 of flat ellipse taper with mozzle axis symmetry.
Described flange form mozzle aperture can change according to the flow needs.Described petal disc and main body junction are two flat ellipse taper reinforcements, and petal disc can be out of shape, and the reliability height guarantees the tiny uniformity of water distribution.Described nozzle body external cylindrical surface is provided with reinforcement, is provided with the planar whippy fin of spiral, makes main body can not be out of shape easy installation and removal.The mozzle external cylindrical surface is provided with reinforcement.The secondary ring flange 7 of mozzle is pressed in the taper draw-in groove 6 on the main ring flange 1, and mozzle can not come off during dismounting.Mozzle, main body pipe, petal disc are injection molded by engineering plastics, use the distortion of also can not corroding and wear out under relatively poor condition of water quality.。
Water is entered by the mozzle R shape mouth at shower nozzle top, quicken vertical drop to petal disc (annotate: petal disc works the peptizaiton that dabbles) through the head natural gravity, petal disc is set up jointly by 6 whirlwind shape petals, is provided with hydrophobic gap between petal and the petal, guarantees that water distribution is tiny evenly.
