Abstract
The utility model discloses a spray nozzle head. The spray nozzle head comprises a connection rod which is located at the upper end of the spray nozzle head, an external thread is installed on the outside of the connection rod, the spray nozzle head is connected with a pipeline through the external thread, the lower end of the spray nozzle head is an umbrella-type channel which is connected with spray holes, and the inclined angle of the umbrella-type channel is theta; and the lower end of the umbrella-type channel is provided with a tapered surface channel, the inclined angle of the tapered surface channel is a, and the a is greater than the theta. By means of the umbrella-type channel and the tapered surface channel, the spray nozzle head is good in spraying effect and meets requirements of large spraying areas and high water jet pressure.
Description
Technical field
The utility model relates to a kind of wash mill of paper industry, relates in particular to a kind of spray-nozzle type sprinkler head.
Background technology
Contemporary paper industry, in the running of papermaking, the washing of dehydrating material is most important, and therefore, spray equipment is the indispensable instrument of washing dehydration material.Spray equipment commonly used is umbrella shaped spray nozzle at present.This umbrella shaped spray nozzle comprises the connecting rod of upper end of nozzle, and this connecting rod outer setting has external screw thread, is connected with pipeline by external screw thread.The lower end of this umbrella shaped spray nozzle is the passage of umbrella shape.Although the spray area of this umbrella shaped spray nozzle is larger, the pressure of this nozzle ejection is smaller, and clean result is poor.
Summary of the invention
The utility model provide for the deficiencies in the prior art a kind of spray area large, spray the large spray-nozzle type sprinkler head of hydraulic pressure.
The utility model is realized by following technical measures: spray-nozzle type sprinkler head of the present utility model, the connecting rod that comprises the spray-nozzle type sprinkler head upper end, the outside of this connecting rod is provided with external screw thread, link to each other with pipeline by this external screw thread, the lower end of described spray-nozzle type sprinkler head is the umbrella shape passage, this umbrella shape passage links to each other with spray apertures, and the angle of umbrella shape passage is θ, 60 °≤θ≤90 °; Further improvement of the utility model is, the lower end, bottom surface of described umbrella shape passage is provided with the taper surface passage, and the angle of this taper surface passage is a, a＞θ, and 90 °≤a≤135 °.By umbrella shape passage and taper surface passage, the spraying effect of this spray-nozzle type sprinkler head is good, satisfy spray area large, spray the large demand of hydraulic pressure.
Angle between described umbrella shape passage and the taper surface passage is b, 25 °≤b≤45 °.
The beneficial effects of the utility model are: this spray-nozzle type sprinkler head is by the design of umbrella shape passage and taper surface passage, has a spray area large and spray also enough large effect of hydraulic pressure.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is that A of the present utility model is to view.
Among the figure:
1 is connecting rod; 2 is the umbrella shape passage; 3 is the taper surface passage; 4 is spray apertures
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of spray-nozzle type sprinkler head shown in Figure 2 such as Fig. 1, the connecting rod 1 that comprises the spray-nozzle type sprinkler head upper end, the outside of this connecting rod 1 is provided with external screw thread, link to each other with other pipeline by this external screw thread, the lower end of described spray-nozzle type sprinkler head is umbrella shape passage 2, this umbrella shape passage 2 links to each other with spray apertures 4, and the angle of umbrella shape passage 2 is θ, 60 °≤θ≤90 °; The design of described umbrella shape passage can guarantee that the shower nozzle projected area is enough large; Further improvement of the utility model is, the lower end, bottom surface of described umbrella shape passage is provided with the taper surface passage, and the angle of this taper surface passage is a, and a＞θ, and 90 °≤a≤135 °.The design of this taper surface passage can increase the hydraulic pressure that shower nozzle sprays; Angle between described umbrella shape passage and the taper surface passage is b, 25 °≤b≤45 °.By umbrella shape passage and the twin-channel design of taper surface passage, the spraying effect of this spray-nozzle type sprinkler head is good, satisfy spray area large, spray the large demand of hydraulic pressure.
The utility model can pass through existing techniques in realizing without the technical characterictic of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
