Description

Technical Field

[0001] The utility model relates to the technical field of atomizing nozzles, in particular to a foam atomizing nozzle. Background Art

[0002] Atomizing nozzles are a type of agricultural irrigation system that sprays pressurized water into the air, dispersing it as a mist over fields and crops. They are suitable for water-saving irrigation in flower fields, lawns, green spaces, factories, greenhouses, and agricultural applications. A variety of atomizing nozzles have been developed, each with its own unique features. Foam nozzles are fire-fighting devices that generate and spray air-foam. The foam mixture is piped to the nozzle, where it draws in air at the nozzle outlet, forming air-foam that is then sprayed into the protected danger zone to extinguish the fire. They are primarily used in low-expansion foam spray systems.

[0003] Foam atomizing nozzles are common in existing fire-fighting equipment. They are mainly used to produce fine air foam. Through a special working principle, the foam is evenly covered on the surface of the burning object to form a continuous foam covering layer, which plays a role in blocking, suffocating and cooling. However, the structure of the foam atomizing nozzle in the existing technology is relatively complex, the finished product structure is not compact enough, the nozzle disassembly and assembly operation is relatively cumbersome, and the nozzle surface distribution is limited, resulting in a limited range of foam spraying and limited fire extinguishing ability. To this end, we designed a foam atomizing nozzle to solve the above technical problems. Utility Model Content

[0007] As a preferred solution of the present invention: a plurality of the first nozzles are evenly distributed along the outer circumferential surface of the nozzle body.

[0008] As a further preferred solution of the present invention: the size of the second nozzle is larger than that of the first nozzle.

[0009] As a further preferred solution of the present invention: the material of the O-ring is nitrile rubber.

[0010] As a further preferred solution of the present invention: the first nozzle, the second nozzle and the nozzle body are all made of 304 stainless steel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses a filter, a nozzle body, an O-ring, a first nozzle and a second nozzle in coordination, and a plurality of first nozzles are evenly arranged on the outer surface of the nozzle body, which greatly improves the density and range of foam spraying. At the same time, a second nozzle is provided at the center position of the bottom of the nozzle body, and the size of the second nozzle is larger than that of the first nozzle. When the nozzle body is in use, not only can foam be sprayed in all directions of 360 degrees on its outer surface, but also foam can be sprayed at the center of the bottom of the nozzle body, and the foam spraying amount is large. Therefore, the present device fully and maximizes the number of nozzles under the limited surface area available on the nozzle body, and the distribution is compact and the structure is simple, which greatly improves the range of foam spraying and improves the fire extinguishing ability. At the same time, the present device is provided with an installation thread on the outer surface of the filter, and the filter screen inside the filter is perpendicular to the transportation direction of the foam liquid. The device structure is more compact and compact, and the installation thread ensures that the installation and disassembly process of the device body is simple, and it is highly practical and worthy of promotion.
