The position in face.
After employing above-mentioned technical proposal, the positive effect that the utility model is brought is：The utility model changes biography
The spraying and splashing facility flow adjustment mode of system, it is no longer necessary to shutdown adjustment, cone core pipe is raised and lowered by turn adjusting screw rod
Height, change the incision section of cone core pipe and nozzle exit plane, so as to change the water-outlet area of jet expansion, reach tune
The purpose of amount of restriction, it is convenient to remove and install process, can greatly save cost, and can be with on-line tuning, it is not necessary to shuts down.Adjust
Section seat and spiral case have a style of one's own, and adjustment seat is provided with internal thread, and screw rod is provided with external screw thread, and screw rod is per one angle of turn, all
It will make cone core pipe that some height be raised and lowered, and change the horizontal incision section of cone core pipe and jet expansion, so as to
Change the water-outlet area of jet expansion, be finally reached the flow of adjustment jet expansion, nut is when screw rod turn is to appropriate location
Screwed, to ensure the highly stable of screw rod.
Brief description of the drawings
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model, wherein
Fig. 1 is structural representation of the present utility model.
In accompanying drawing marked as：
Spiral case 1, nozzle 2, main shaft 3, splash box 4, Flow-rate adjustment component 5, screw rod 51, cone tube core 52, adjustment seat 53, spiral shell
Cap 54.
Embodiment
(embodiment 1)
See Fig. 1, a kind of cooling tower spraying and splashing facility of stepless quantity-regulating of the present embodiment, including spiral case 1, nozzle 2, main shaft 3, splash
Water pond 4 and the Flow-rate adjustment component 5 being arranged inside spiral case 1；The sidepiece of spiral case 1 and bottom are respectively arranged with water inlet and water outlet
Mouthful；Nozzle 2 is arranged on the water outlet of spiral case 1；The top of main shaft 2 is arranged in spiral case 1, bottom connection splash box 4；Flow is adjusted
Section component 5 includes the screw rod 51 and cone tube core 52 being connected as a single entity；Cone tube core 52 is arranged at the lower end of screw rod 51, can be with spiral shell
Bar 51 moves down the pelvic outlet plane 21 for cutting nozzle 2 and changes the size of pelvic outlet plane 21.Flow-rate adjustment component 5 also includes
The adjustment seat 53 being arranged on spiral case 1；It is threaded in adjustment seat 53, for being engaged with the screw thread of screw rod 51.Flow-rate adjustment group
Part 5 also includes the nut 54 for standing screw 51.Datum line is carved with adjustment seat 53, the datum line represents cone tube core 52
The position that tip is generally aligned in the same plane with pelvic outlet plane 21.
The flow rate adjusting method of the cooling tower spraying and splashing facility of stepless quantity-regulating, comprises the following steps：
Step 1: the structure of the cooling tower spraying and splashing facility of stepless quantity-regulating is determined according to Fig. 1；
Step 2: the pitch for determining the screw rod 51 of the cooling tower spraying and splashing facility of the stepless quantity-regulating of production is h, cone tube core 52
Central angle be α, the outlet diameter of nozzle 2 is D0, the area of pelvic outlet plane 21 is SD0；When the tip and outlet of cone tube core 52
After plane 21 is generally aligned in the same plane, continue to decline, often decline a pitch, cone tube core 52 cuts the diameter at pelvic outlet plane 21
For D1, calculate actual nozzle outlet water-outlet area S nowy, obtain n actual nozzle water outlet during 1~n pitch of decline
Open area Sy, n is natural number；
Step 3: with formula Q=μ Sy·√2gH·3600m3The n nozzle that/h is calculated when declining 1~n pitch is real
Border water flow Qy, n is natural number, and μ is discharge coefficient, and g is acceleration of gravity, and H is nozzle operation head rice number；This is stepless
The actual water flow Q of nozzle during the n Flow-rate adjustment component movement of the cooling tower spraying and splashing facility of tune amountyForm is made；
Step 4: needed to adjust the upper-lower position of the screw rod 51 of Flow-rate adjustment component 5 at any time according to operating mode during operation, and then
Adjust nozzle water flow Qy。
Example：Known μ=0.9, α=300, D=0.070m, h 0.001m, often one pitch of decline y=0.001m, H
=0.8,
Then：Qy=0.9x { 0.25x3.14x (0.07)2-0.25x3.14[tg(30/2)x0.001]2}·√2gH·3600
=44 (m3/h).
Result of calculation：When turn screw rod 51 makes cone core pipe 52 move down 1mm, the flow of nozzle is 44m3/h.
If pitch is designed as 4mm, flow at this moment is：
Q=0.9x { 0.25x3.14x (0.07)2-0.25x3.14[tg(30/2)x0.004]2√ 2gH3600=
27.7(m3/h)。
Particular embodiments described above, the purpose of this utility model, technical scheme and beneficial effect are carried out to enter one
Step describes in detail, should be understood that and the foregoing is only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
