working principle)

When the pressure of water through the pipeline mixer , some of water flower into the tank by the  water pipe, the majority of water along the pipe into the mixed  ratio of the nozzle ,then out to the diffusion tube. When innto the nozzle, the caliber get shorten, the flow rate increases, due to  the disorderly diffusing operation of landscape orientation from jetting Particle,Come into being

the mixing chamber of Low pressure between the nozzle exit with the diffusing tube,the water which  into the tank will squeeze the foam solution that was stored in capsules by the outting for liquide tube, through the hole board go into the mixed  ratio for the mixing chamber of low pressure with the large of pressure for the mixed  ratio of the nozzle together get the water of 3% or 6% foam mixture concentrate, then it will be transported to the produce equipment of foam, to make air foam use for saving   A, B, C type liquid fire and wood, paper, textiles and other solid fire.

(The advantages for bladder and chamber type tank)

1. The core components for equipment which is the pressure-type proportion mixer with resistantting corrosion and  long life advantages.

2. The  ball valve, check valve, ball valve of the components for the equipment  are national with high-quality and  brand-name products which are reliable operate equipment.

3.The material for the tank is hot-rolled steel sheet, which take the technology of arc welding, the maximum pressure is 1.6MPa.

4. The diaphragm in the tank use high-strength composite rubber membrane,can always separate the water and foam solution to ensure the residual foam concentrate can continue use,and will not effect the and will not affect the life of foam concentrate so as to avoid the foam solution waste.

5.In general ,standard equipment will be fit france-type ball valve in the inlet pipe and outting for liquide tube. If users have special requirements, inlet pipe, foam mixture tube, outting for liquide tube can install pneumatic or electric ball valve, also can provide the control box that can control switch for valve.

6. With the function of  over-pressure protection . Equipment might occur the phenomenon of over-pressure in the course of using, And the device has a safety valve, When the actual pressure exceedding the pressure for relief valve,then pressure relief automatically to protect the device.
