The nozzle is a kind of daily hardware. It is a key part in many kinds of spraying, spraying, oil spraying, sandblasting, spraying and other equipment, and plays an important role. There are many classifications of nozzles, which can be divided into spray nozzles, fuel injection nozzles, etc. according to different functions, materials, and application industries. Nozzles are used in a wide range of industries, including dozens of industries such as vehicles, papermaking, textiles, and electronics. The nozzle structure is different, the processing efficiency and the service life of the nozzle are also different. There are mainly four types: cylindrical straight hole, conical, special nozzle and combined type. Let’s learn about the nozzle knowledge together!
What are the nozzle models:
1. Nozzles can be divided into two categories, burner nozzles (military, civilian) and non-burner nozzles.
2. According to the function of the nozzle, the nozzle can be roughly divided into: spray nozzle, oil injection burner, sandblasting nozzle, and special nozzle.
3. According to the classification of materials, it can be divided into: metal nozzles, plastic nozzles, ceramic nozzles, alloy nozzles.
4. According to industry classification, it can be divided into: petrochemical nozzles, agricultural nozzles, textile nozzles, papermaking nozzles, printing nozzles, environmental protection (desulfurization, denitrification, denitrification, dust removal, etc.) nozzles, spraying nozzles, iron and steel metallurgy nozzles, electronic nozzles, food nozzle.
5. Classified by shape, it can be divided into hollow cone nozzles, solid cone nozzles, square nozzles, rectangular nozzles, oval nozzles, fan nozzles, column flow (direct current) nozzles, two-fluid nozzles, multi-fluid nozzles, etc.
6. Nozzles for special industries: flame nozzles, Texaco nozzles, granulation nozzles, etc.
In short, the application of nozzles is very wide, involving almost every field.

(4) The circuit board is useful for Saigang nozzles.
5. Pharmaceutical factory: more atomizing nozzles
(1) Granulation nozzle.
(2) Coating nozzle, that is, the sugar coating on the surface of the medicine.
6. Food industry
(1) Cleaning of dishes.
(2) Cleaning of fruits, vegetables, etc., such as cleaning and hair removal of strawberries.
(3) The purification workshop has an air shower room and uses air shower nozzles.
7. Thermal power plant
(1) Large-flow nozzles, such as silicon carbide nozzles and spiral nozzles, are used for desulfurization and dust removal.
(2) Used in the cooling system before the boiler.
8. Garbage disposal
(1) Use an atomizing nozzle to spray a spice on the garbage to get rid of the smell.
(2) Use nozzles such as solid cones to reduce dust.
9. Radiator: Because of the spraying treatment, there are clip nozzles.
10. Steel pipe factory: wide-angle and multi-part paint nozzles made of titanium.
(1) High-pressure derusting nozzles for steel pipe plants.
(2) Coating nozzles inside and outside the steel pipe.
11. The pressure vessel factory uses a solid cone nozzle.
12. Winery
(1) Beauty nozzles and mist nozzles on beer, wine and other beauty machines.
(2) Multi-spray heads or rotating nozzles for cleaning bottles and cans.
13. Petroleum and chemical industry
(1) Cleaning nozzles for bottles and cans, multi-head or rotary nozzles.
(2) Cooling nozzles for bottles and cans.
(3) In order to fully reflect the chemical substances, a nozzle consisting of an outer shell and an inner core is used.
14. Cooling tower: Use large flow nozzles, such as clip nozzles, spiral nozzles, etc.
15. Drying equipment: Air atomizing nozzles or metal fine atomizing nozzles are used in spray or atomization drying equipment.
16. Wood drying: Nozzles are used to prevent the wood from cracking.
17. Dust removal, smoke removal, waste gas treatment
(1) For use on wet hair dusters or equipment.
(2) It is used for the purification of waste smoke and gas in some enterprises, generally using large flow nozzles.
18. Lubrication
(1) Gear lubrication.
(2) Spraying of the release agent on the plastic spraying equipment.
(3) Cable lubrication.
(4) Die lubrication on large forging presses.
19. Glass Factory
(1) Clean the formed glass or FRP.
(2) cooling.
20. Sterilization boiler: use fan-shaped nozzles to sterilize and disinfect.
21. Cigarette factory
(1) Humidification and dust reduction in the large space of the tobacco factory.
(2) Air atomizing nozzles are used to spray fragrance.
(3) Tobacco factories use a large number of filters.
