Abstract
The utility model relates to a spray nozzle, which is capable of regulating the flow quantity. The utility model comprises an outer casing, a draft tube [3] and an injecting nozzle [4], wherein the outer casing is formed by connecting the lower section [5] of the outer casing and the upper section [2] of the outer casing by screw threads; the upper end of the lower section [5] of the outer casing is provided with a locating convex ring [7] which is tightly pasted on the outside of the injecting nozzle [4], and the calibre of the injecting nozzle [4] is in a downwards contractive shape and is formed by splicing cambered plates [8]; the upper ends of the cambered plates [8] are hinged and positioned in the upper section [2] of the outer casing, and the lower ends of the cambered plates [8] are opened. The utility model has the advantages of simple structure, convenient operation and ideal effect. Under the condition of equal water distribution, the operational water quantity between the water cooling tower in a circulating water field can be adjusted to reduce the running cost of the circulating water field.
Description
Technical field
The utility model relates to a kind of shower nozzle, particularly a kind of adjustable throttle amount shower nozzle that is applied to the recirculated water cooling tower.
Background technology
The recirculated water cooling tower all is to define by the maximum one design under the least favorable meteorological condition of tower location both at home and abroad at present.And the most of areas of China are typical seasonal weathers, and most its cooling conditions of time are all superior than cooling tower design condition in promptly 1 year.Therefore from angle energy-conservation and reduction operating cost, non-least favorable meteorological condition wishes to occur two kinds of operation conditions often: a kind of is a part of cooling tower in recirculated water field machine that blows in, allow the super design flow of cooling tower move, another part cooling tower stoppage in transit blower fan allows cooling tower less than the cooling of design flow operation carrying out nature.Another kind is that the recirculated water place has the cooling tower machine that all do not blow in, and each tower carries out the nature cooling all less than the design flow operation.Yet the water-distribution nozzle of present cooling tower various types, all are fixing bore classes, excess was very limited when the super design flow of cooling tower moved, often it is inhomogeneous water distribution to occur less than the design flow operation, the nature cooling effect is very poor, if it is the water-distribution nozzle specification is carried out seasonality replacing, both loaded down with trivial details, cost is high, damages shower nozzle or interface again easily.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved adjustable throttle amount shower nozzle is provided, and can regulate flow as required, thereby reaches purpose energy-conservation and reduction operating cost.
The purpose of this utility model can realize by following technical measures: this shower nozzle comprises shell, mozzle, nozzle, the nozzle diameter adjusting device that is provided with the double as nozzle housing and can supplies to rotate on shower nozzle.
The nozzle diameter adjusting device comprises shell, nozzle, shell is got up by thread connection by shell hypomere and shell epimere, shell hypomere upper end is provided with positioning convex ring and tightly is posted on the nozzle outside, the bore of nozzle is for contraction-like downwards, at least splice by three arcs and surround bore, hinged location in the shell epimere, arc upper end, the lower end is open, the rotation case hypomere can make it move the stretching degree of the arc that changes nozzle vertically, thereby the bore that makes nozzle becomes big or diminishes, and reaches the purpose of regulating flow.
The beneficial effects of the utility model are: under the uniform prerequisite of water distribution, by regulating the bore of nozzle, adjust the operation water yield between the cooling tower of recirculated water field, make full use of the ability that cools naturally of cooling tower and the cooling allowance of favourable meteorological condition or recirculated water field, reduce the operating cost of recirculated water field.It is simple in structure, and is easy to operate, satisfactory for result.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is structure of nozzle figure;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, this shower nozzle comprises shell, mozzle [3], nozzle [4], and the shell upper end is provided with the screw-internal thread fit on external screw thread and the installed part [1], and mozzle [3], shell are fixed on the installed part [1].
On shower nozzle, be provided with the nozzle diameter adjusting device, it comprises shell, nozzle [4], shell comprises shell hypomere [5] and the shell epimere [2] that is connected as a single entity with trickle spare [6], shell hypomere [5] and shell epimere [2] get up by thread connection, and shell hypomere [5] upper end is provided with positioning convex ring [7] and tightly is posted on the medium position of nozzle [4] outside.The bore of nozzle [4] is made up of 5～8 arcs [8] for contraction-like downwards, and the outside is the position overlap joint in the same way, cross section is the disc type zigzag, sees Fig. 3, and arc [8] upper end is hinged with annulus [9], annulus [9] is weldingly fixed on mozzle [3] lower end, and nozzle [4] lower end is open.
During use, this shower nozzle is installed on the cooling tower by installed part [1], when needs reduce the cooling tower operation water yield, rotational shell hypomere [5], it is moved up, bulge loop [7] on the shell hypomere [5] then forces the arc [8] of nozzle around inwardly shrinking with annulus [9] hinged place, and nozzle [4] bore diminishes; When needs increase the cooling tower operation water yield, rotational shell hypomere [5] moves down it, and the bulge loop [7] on the shell hypomere [5] then leaves the arc [8] of nozzle, flow action outwards opens near bulge loop [7] arc [8] of nozzle, and it is big that nozzle [4] bore becomes.By regulating nozzle [4] bore, regulate flow, the energy-saving effect when reaching the cooling tower operation.
Nozzle diameter adjusting device of the present utility model also can adopt alternate manner to realize, but so long as the rotation by nozzle housing changes the nozzle diameter size, all belongs to protection domain of the present utility model.
Claims (2)
1, a kind of adjustable throttle amount shower nozzle comprises shell, mozzle, nozzle, it is characterized in that the nozzle diameter adjusting device that is provided with the double as nozzle housing and can supplies to rotate on shower nozzle.
