Foam tank storage and filling foam liquid ordinary foam extinguishing equipment pressure foam extinguishing device

Description :

　　Water has long been recognized as a fire extinguishing medium, but there are some fires that cannot be extinguished solely by water.

　　Foam: small in size, good in fluidity, with a certain degree of adhesion, it can well isolate the fire source and oxygen in the air, so as to achieve the effect of extinguishing fire.

　　There are many types and models of foam extinguishing agent, and the scope of application is also different. It is not enough to use foam liquid only, but also needs suitable fire-fighting equipment.

　　The pressure type foam proportioning device is used to store foam extinguishing agent and replace foam extinguishing agent through the pressure type foam proportioner using the water supply of the pump set, and mix with the water supply in a certain proportion to form foam mixture.

　　Before filling foam liquid, all valves of PHYM (L) series pressure type proportional mixing device must be closed, two exhaust valves must be opened, water from 1/3 to 1/2 of the storage tank shall be filled between the storage tank and the storage tank through the water inlet pipe and the drain port, then the liquid filling port shall be opened, an inch rubber pipe shall be inserted from the liquid filling port to the bottom of the tank, and foam extinguishing agent shall be injected into the storage tank through the crossover pipe. When water is discharged from the exhaust port, the drain valve shall be opened, and the water shall be drained at a flow similar to the foam liquid filling flow until the foam liquid is fully filled. After filling is completed, close the filling port and drainage valve, open the inlet valve, and slowly fill the space between the tank and the tank with water until water flows out from the exhaust port. Close the exhaust valve and inlet valve, and then rinse the scattered fire extinguishing agent outside the device with clean water.
