Knowledge Analysis of Fan Nozzle Structure

Fan-shaped nozzles have many uses, and it is not difficult to distinguish them in daily life. Fan nozzles are usually connected to pipes, especially in those plantations. Connect the pipeline with a fan nozzle to spray water. We know that the fan nozzle is used in this way, so have we considered the structure of the fan nozzle? Why can it spontaneously spray water? For us, these problems should not have been roughly thought about! So today, Xiao Mo teaches you about the structure of fan nozzle.

Product parameter

The maximum injection angle is 60- 170 degrees. Under the pressure of 3Mpa, the liquid velocity range is 5.5- 140 L/min. The thread dimensions of the spiral nozzle are 1/4, 3/8, 1/2, 3/4, 1-1/2, 2, 3, etc. , the conventional thread is English pipe thread. If you need other threads, please contact Beijing Kefeng Spraying Equipment Co., Ltd. Fan spray form.

The fan-shaped nozzle structure directly produces a flat and uniform jet from the nozzle shape, and the jet has good compactness and the diffusion angle can be changed in a wide range. Its industrial application varies according to the flow rate, velocity, injection angle and coverage. This nozzle has also been successfully used in high-pressure water jet. Axial fan-shaped nozzle is a fan-shaped jet directly formed by liquid flowing through elliptical nozzle hole, which is generally formed by the vertical intersection of wedge-shaped nozzle hole with conical nozzle hole at a certain angle.

Sector nozzle structure

It is not difficult to see that the fan-shaped nozzle structure is formed by the intersection of a wedge-shaped nozzle and a conical nozzle hole, and the pressure is within 1mpa. In order to facilitate machining, the "wedge" of many fan-shaped nozzles is not a simple straight groove, but an arc groove, that is, technically, the horizontal milling groove is changed into an arc milling groove.

The origin of high-pressure fan nozzle is the same as that of low-pressure fan nozzle, but its structure has its own characteristics due to different pressures, as shown in Figure 4. Due to the diffusivity of the fan nozzle, there is no need for strict convergent cross section. In fig. 4, the pressure of a-type nozzle is 75mpa, and a is 20 -90 degrees. The disadvantage of this kind of connecting thread is that it is not conducive to the adjustment of the position of the fan jet, because the fan jet is directional.

The working pressure of fan nozzle structure is as high as 200mpa, d=0.88mm, a= 10 -20 degrees. The cylindrical section of the fan nozzle structure is completely different from that in Figure A, which is due to the high pressure requirement. The fan nozzle structure is a combined fan nozzle, which seems to be complicated to process, but it is accepted by people because of its reliable molding, different materials, wide application and easy serialization. Under the pressure of 15mpa, the relationship between different jet angles of fan nozzle and target distance and jet width shows that the jet coverage is much larger than that of cylindrical nozzle.

trait

In the fan-shaped spray pattern of the fan-shaped nozzle, the edge of the spray pattern is clearly distinguishable, and the guide plane processed by fine technology provides a uniform and high-impact spray pattern. ? The spray channel is large and smooth, which reduces the blocking phenomenon. ? Fan-shaped nozzle is a nozzle product specially developed by Beijing Kefeng Spray Equipment Co., Ltd. Due to the influence of the earth's gravity, fan-shaped spray at various angles will produce "edge effect", that is, the fan-shaped outline of the spray will produce a sharp edge, and the spray particles will be fine and uniform, and the spray particles will be of moderate size. When multiple nozzles are arranged, 25%~30% overlap is needed to make the arrangement uniform in the whole direction. It can produce multi-angle fan spray. The spray water flow is uniform and the droplet size is moderate. The unit combination connection mode is adopted, which is convenient for installation and replacement. You can add a filter screen and it is easy to clean.

More product materials: spiral nozzles can be installed or replaced on most pipeline systems. Available nozzles are NPT or BSPT (external) thread types. Generally 1/4 "-4 "nozzles can be made of Cu, 304SS, 3 16SS, 3 16L, PVDF and? Made of PP or silicon carbide. Stainless steel (SS304, 303, 3 16, 3 16L), brass, silicon carbide, plastics (PVC, ABS, FUD), ceramics and other materials.

Fan nozzle can play a role in all aspects of our lives, and using fan nozzle can reduce a lot of labor. After all, the fan nozzle can automatically spray water or fertilize. Today, we also learned about the structure of fan-shaped nozzle, which is of great help to friends who want to make fan-shaped nozzle by hand. Knowing the structure of fan nozzle is believed to be helpful for self-made fan nozzle. So if you want to make a better fan nozzle, you need to know more about the structure of fan nozzle.
