1
Product introduction and implementation standard: GB20031-2005 pressure foam proportioning device is suitable for large and medium scale foam fire protection projects such as oil depots, petrochemical enterprises, oil depot docks, oil tankers, drilling platforms and power plants
nbsp; The maximum flow range of the proportioner is 8 ~ 200L / S; The volume range of storage tank is 300L ~ 25000l (i
e
0
3m3 ~ 25m3) According to the installation method, it is divided into mobile type and fixed type The fixed type is divided into capsule type and non capsule type according to the internal structure; According to the shape and structure, it is divided into vertical and horizontal 2、 Working principle and Characteristics , The working principle of pressure type foam proportioning device is 1
PHYM tank contains capsule   The whole set of equipment consists of proportioner, steel storage tank, capsule, water inlet system, liquid outlet system, one-way valve, safety valve, control valve, pressure gauge, exhaust system and pipeline The proportioning mixer can make the water and foam liquid mix in a certain proportion automatically
When the pressure water passes through the proportioning mixer, part of the water enters the water tank of the storage tank through the "inlet valve" pipeline, and squeezing the capsule
Due to the slight pressure difference between the front and the back of the nozzle, the foam liquid in the capsule is extruded through the suction pipe and mixed with water to become a foam mixed liquid flow, and foam is discharged through foam generator or other spraying equipment to extinguish the fire
nbsp; Features: , A rubber capsule is made in the storage tank to separate the water from the foam liquid
After each use, the water and foam liquid can not be mixed, and the performance of the original foam liquid can not be maintained, and it can be used continuously to avoid the waste of the foam liquid
2
No capsule in PHY storage tank , The whole set of equipment consists of proportioner, steel storage tank, water inlet system, liquid outlet system, one-way valve, safety valve, control valve, pressure gauge, exhaust system and pipeline The proportioning mixer can make the water and foam liquid mix in a certain proportion automatically
When the fire water passes through the proportioning mixer, part of the water enters the tank cavity through the "inlet valve" pipeline, and squeezing the foam liquid
Due to the slight pressure difference between the front and the back of the nozzle, the foam liquid is extruded through the suction pipe and mixed with water to become a foam mixed liquid flow, and the foam is sprayed out of the foam by the air foam generator or other spraying equipment to carry out the fire fighting work
nbsp; Characteristics: there is no capsule in the storage tank
When water enters the tank, it directly contacts with the foam liquid
After each use, the water and foam should be drained out
The tank wall is rinsed clean, dried and refilled with foam liquid
There is no loss caused by capsule rupture
Suitable for direct contact with metal cans
nbsp; 3、 Usage conditions , The pressure and flow range of the fire pump matched with the mixing device must be within the specified performance requirements of the mixing device The mixing device must be used in the specified working pressure range and flow range, otherwise the mixing ratio will be affected and the foam quality will be reduced
nbsp; The pressure of the mixing device in the specified working pressure range depends on the friction pressure loss of the foam fire extinguishing equipment and the equivalent pipe length
Therefore, the necessary calculation for the pipeline system should be made to determine whether the installation location of the proportional mixing device is appropriate and whether the type is suitable
nbsp; Four, instructions for use (see PHYM pressure type foam mixing device principle diagram) 1, start the fire pump and the pipeline has pressure water, first open the inlet valve 1, outlet valve 2 and inlet valve 3
2
Adjust the opening of the outlet valve 2, so that the pressure gauge displays the rated working pressure of the mixing device, and is stable at a certain value
3, when the tank enters the pressure water and the pressure rises to the working pressure, the outlet valve 4 can be opened, the mixing of the foam liquid and the pressure water is automatically adjusted to the ratio of 6% (or 3%), and the foam mixture is started to output to the system
4
When stopping the liquid supply, first close the liquid outlet valve 4 (to prevent the pressure water from flowing into the capsule), then close other valves, stop the pump and stop the work
5
Method of initial perfusion foam:   ⑴  Close valve 6 and open valve 8, valve 9 and valve 7 ⑵  Open flange cover 5, use hand pump to add foam liquid   to rubber bag; ⑶  When the foam liquid spills from the valve 7, the foam liquid can be filled
Close valve 7
6
During water test, open valve 8 and valve 3 to supply pressure water
When exhaust valve 8 sprays water, it can be closed to keep the storage tank in a standing state 5、 Maintenance , 1
Frequently check whether the flange cover is sealed and whether the action of each valve is flexible and reliable
2, when filling foam liquid, it should be kept clean in the tank, not mixed with oil or other foam liquid, and should not be mixed with aging foam liquid
3
Foam should not be allowed to be exposed to the sun and stored in a small temperature field
The foam liquid that has been stored for more than two years shall be sampled before being used and can be used after being qualified
The lost foam should be updated in time
And record the date of changing the new bubble
4
The storage tank with capsule shall be subject to leakage test every six months
The test method is to open the drain valve 9
If there is a leakage of foam, it proves that the capsule is damaged
It should be repaired or replaced in time
5
When changing the foam liquid, a foam injection simulation test should be made to check the fire extinguishing system to check whether the working condition of the fire pump, proportional mixing device and foam generator is normal and reliable
If abnormal, it should be repaired in time
6, replace the failure foam liquid, the device should be fully cleaned, the method of cleaning the capsule is:   First, put the remaining foam in the capsule first, then open the water cavity drain valve 9, then connect the compressed air (pressure 0
02 ~ 0
1MPa) from the capsule vent valve 7, open the lower part of the tank bottom drain valve 6, blow up the foam residue in the capsule
nbsp; 2
Close the valve 6, open the valve 8, fill the water from the mouth 5 to the capsule and clean the inner surface of the capsule, then open the valve 6, squeeze the water out of the valve 7 through the compressed air, and continue to blow the capsule with compressed air for thirty minutes, thoroughly drying the capsule and re filling the foam liquid
