Abstract
A kind of gooseneck type nozzle, belongs to water flow device calibrating flow instrument technical field.Comprise back pressure section, transition section and nozzle end, described transition section is divided into First Transition section and the second transition section, and described two transition sections are flat fan structure, between be arc-shaped transition, nozzle end is flat outlet.The utility model makes simple, easy to operate. and good fluidity, can not cause loose flower phenomenon of splashing.Nozzle of the present utility model has the cascade flowing downward vertically of sizing width, and make commutator fast for commutating period, calibration accuracy is high, and Shi Shui Installed puts more accurately more perfect.
Description
Technical field
The invention belongs to water flow device calibrating flow instrument technical field, particularly relate to a kind of gooseneck type nozzle, for commutator rectifying installation.
Background technology
Existing oscillating nozzle is hemispherical dome structure, and the current of its ejection are anxious, produce fluctuation, the phenomenon and nozzle water flow shakiness dabbles to measuring instrument.The length limited system of existing structure nozzle, it is cylindrical liquid stream that liquid is left to what nozzle was formed again by the jet pipe in nozzle, few when nozzle is many during flow instability when swinging commutation, affects discharge stability.
Summary of the invention
For the technical matters of above-mentioned existence, the invention provides a kind of gooseneck type nozzle, when its energy discharge detects, commutator is short for commutating period, and current are the loose flower of line style, and discharge accuracy of detection is high, does not produce fluctuation to instrument.
The object of the invention is to be achieved through the following technical solutions:
The present invention includes back pressure section, transition section and nozzle end, described transition section is divided into First Transition section and the second transition section, and described two transition sections are flat fan structure, between be arc-shaped transition, nozzle end is flat outlet.
Further, described nozzle end discharge area equals 0.95 ~ 1 times of back pressure section inlet-duct area.
Further, described First Transition segment length L1 is 4 ~ 6 times of back pressure section inlet diameter d.
Further, the angle [alpha] between described First Transition section and surface level is 15 ~ 20 °.
Further, described second transition section length L2 is 1.5 ~ 3 times of back pressure section inlet diameter d.
Further, the angle beta between described second transition section and surface level is 10 ~ 15 °.
Further, the length breadth ratio of the flat outlet of described nozzle end is between 1:10 to 1:16.
Beneficial effect of the present invention is:
1. the present invention adopts two flat fan-shaped transition section arc transition, with its level angle of limit and length, plays the effect of current stabilization.Nozzle end is the flat outlet of gooseneck type, the water flow stationary of its ejection.
2. the present invention makes simply, easy to operate, good fluidity, can not cause loose flower phenomenon of splashing.Nozzle of the present invention has the cascade flowing downward vertically of sizing width, and make commutator fast for commutating period, calibration accuracy is high, makes water injector more accurately more perfect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
In figure: 1. flange, 2. back pressure section, 3. First Transition section, 4. the second transition section, 5. nozzle end, 6. coupling bolt, 7. commutator, 8. spacing angle steel, 9. angle cleat, 10. pressing plate.
Embodiment
Below by embodiment and accompanying drawing, the invention will be further described.
Embodiment 1: as shown in Figure 1 and Figure 2, comprises back pressure section 2, transition section and nozzle end 5, and described transition section is divided into First Transition section 3 and the second transition section 4, and described two transition sections are flat fan structure, between be arc-shaped transition, nozzle end 5 is flat outlet.
Described nozzle end 5 discharge area equals 1 times of back pressure section 2 inlet-duct area.
Described First Transition section 3 length L1 is 5 times of back pressure section 2 inlet diameter d.
Angle [alpha] between described First Transition section 3 and surface level is 18 °.
Described second transition section 4 length L2 is 2 times of back pressure section 2 inlet diameter d.
Angle beta between described second transition section 3 and surface level is 12 °.
The length breadth ratio of the flat outlet of described nozzle end 5 is between 1:10 to 1:16, and this example is 1:10.
The present invention is fixed on commutator 7 by angle cleat 9, commutator 7 is also connected with spacing angle steel 8 and pressing plate 10, makes nozzle of the present invention indeformable.Back pressure section 2 end is connected on water standpipe by flange 1.This carrys out flowing water when upwards flowing, and by hemispherical dome reducing, more upwards becomes flat narrow stream gradually by flat fan body, then by two flat fan transition sections, by flat burner end 5 curtain flowing downward vertically.
Embodiment 2: this example as different from Example 1: in this example
Described nozzle end 5 discharge area equals 0.95 times of back pressure section 2 inlet-duct area.
Described First Transition section 3 length L1 is 4 times of back pressure section 2 inlet diameter d.
Angle [alpha] between described First Transition section 3 and surface level is 15 °.
Described second transition section 4 length L2 is 1.5 times of back pressure section 2 inlet diameter d.
Angle beta between described second transition section 3 and surface level is 10 °.
The length breadth ratio of the flat outlet of described nozzle end 5 is 1:16.
Embodiment 3: this example as different from Example 1: in this example
Described nozzle end 5 discharge area equals 0.98 times of back pressure section 2 inlet-duct area.
Described First Transition section 3 length L1 is 6 times of back pressure section 2 inlet diameter d.
Angle [alpha] between described First Transition section 3 and surface level is 20 °.
Described second transition section 4 length L2 is 3 times of back pressure section 2 inlet diameter d.
Angle beta between described second transition section 3 and surface level is 15 °.
The length breadth ratio of the flat outlet of described nozzle end 5 is 1:12.
