[0002] The foam fire extinguishing system is one of the preferred fire extinguishing systems nowadays. The foam is generated by the foam generator to isolate the combustion body from the air, so that the fire source is suffocated due to lack of oxygen, and the heat is taken away with the foam breakage, which has the effect of cooling. According to the foaming ratio of the foam liquid, it is divided into three types: low, medium and high. Among them, the volume of the foam in the medium foam generator is 21 to 2000 times the volume of the mixed liquid. The input end of the foam generator is connected with a proportional mixer. After the mixer mixes the clear water and the foam stock solution in the foam tank in proportion, it is input into the foam generator to form foam and spray it out. The existing foam generator mainly has the following disadvantages: because the foam needs to be sprayed out at a faster speed , the usual foam generator can only be applied to low-expansion foaming, and it is difficult to coordinate between the foam ejection speed and the expansion ratio, especially for the foam generator that directly inputs the foam mixture, it is difficult to fully diverge to form foam

Embodiment 1
[0031] like Figure 1 to Figure 4 As shown, a medium-fold foam generator in this embodiment includes a cylinder body 1 and a generator valve core 2, the generator valve core 2 is made of brass, and the generator valve core 2 is made of brass material, which can effectively To prevent foam corrosion, one end of the generator spool 2 is connected to the inside of the cylinder 1, and the other end of the generator spool 2 can be connected to an external input pipeline. The input pipeline will introduce the foam stock solution and water fully mixed by the proportional mixer, and the cylinder will 1 is provided with a drying net 3, and the interior of the cylinder 1 is provided with two drying nets 3 along the axial direction, and the two drying nets 3 are arranged at the exit end of the cylinder 1. It is easier to break out the foam and produce a large amount of foam. In the present embodiment, the number of meshes of each drying net 3 is 20 orders, that is, the drying net 3 of ev...

The invention relates to a medium-expansion foam generator which comprises a barrel and a generator valve core, wherein one end of the generator valve core is connected into the barrel; the other end of the generator valve core can be externally connected with an input pipeline; and a drying net is arranged in the barrel. By adopting the structure, the foam mixed liquid is led in through the generator valve core externally connected with the input pipeline and is foamed and ejected in the barrel with the drying net, and the expansion rate of foam is high.
