Abstract
The utility model belongs to the fire fighting equipment, and particularly relates to a flow balance self-controlling type foam proportioning device which can provide water and fire-fighting foam with an accurate proportion for storage areas of Type A, Type B and Type C flammable and explosive materials. The flow balance self-controlling type foam proportioning device comprises a working pipeline system and a single-chip control system. In the technical scheme of the working pipelines system, a water storage device is connected with a fire pump through a water flow detector; a foam liquid storage tank with a valve is connected with a foam liquid flow detector through an electric valve; the foam liquid flow detector is arranged on a foam liquid injection pipeline between the foam liquid flow detector and the water flow detector; and the fire pump is connected with a foam generator and a power supply. In the technical scheme of the single-chip control system, a single-chip system is respectively connected with the electric valve, the foam liquid flow detector and the water flow detector; and the electric valve and the single-chip system are connected with the power supply. The utility model has the advantages of simple structure, convenient use and low cost.
Description
Technical field
The utility model belongs to extinguishing device, is specifically related to a kind of Class A that is, the storage tank field of Class B and Class C combustible and explosive articles provides the automatic control flow equilibrium formula foam proportioning unit of water and the accurate ratio of fire foam.
Background technology
The froth fire extinguishing system of China's use now mainly contains negative pressure circular pump type foams mix system, pressure type foam proportioning system, pumps into balanced type foam proportioning unit and metering-type and injects foam proportioning unit.Wherein negative pressure circular pump type foams mix system exists suitable flow, pressure limit is little, the inaccurate shortcoming of mixed proportion.It is pressure vessel that the pressure type foam proportioning system exists tank body, manufacturing and the shortcoming that maintenance difficulty is big, capsule is very easily torn, mixed proportion is inaccurate, service condition is harsh.Pump into the balanced type foam proportioning unit and exist following defective: 1, complex structure, cost height, the big and high shortcoming of specification requirement of Operation and Maintenance difficulty; 2, foam pump malfunctioning after, systemic breakdown can not be worked, without any remedial measure at all; 3, mixed proportion is inaccurate.Metering-type injects foam proportioning unit and has following defective: 1, because its foam solution injection phase is in the extrusion end of fire pump, so the outlet pressure of its foam pump must be greater than the outlet pressure of fire pump, otherwise can not inject, also may occur flowing backwards; This has just proposed higher requirement to the selection of foam pump, and used power is bigger; 2, because any foam solution all has certain corrosivity, foam pump must be selected stainless steel or copper impeller for use, and cost is too high, otherwise makes cylinder iron impeller, is corroded easily and embroiders deadly, can not start at the crucial moment of fire extinguishing; 3, in case run into the reason that foam pump is embroidered dead, power failure or others, when foam pump can not start, whole system was in paralyzed state, can not use, without any remedial measure; 4, because it uses foam pump to inject foam solution to system, the control of its flow size is by changing the rotating speed of foam pump, and the frequency converter that the rotating speed of its foam pump disposes by foam pump again changes voltage to be finished, so complex structure, cost is too high.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, security performance is high, the easy to use and low automatic control flow equilibrium formula foam proportioning unit of cost.
The object of the present invention is achieved like this: comprise working line system and single-chip computer control system, a, working line system: comprise that water storage device passes through the discharge detector and links to each other with fire pump; The foam solution basin that has valve links to each other with the foam solution flow detector by electrically operated valve; Described foam solution flow detector is arranged on the foam solution flow in pipes between discharge detector and the fire pump; Described fire pump links to each other with foam producer; Fire pump links to each other with power supply; B, single-chip computer control system: comprise SCM system respectively with electrically operated valve, the foam solution flow detector links to each other with the discharge detector; Electrically operated valve links to each other with power supply with SCM system.Described fire pump is in parallel with the diesel oil fire pump.
The utlity model has following advantage:
1, the utility model is arranged on the suction side of fire pump with the injection phase of foam solution, directly sucks by fire pump, does not use foam pump and collocation mechanism thereof, has reduced the cost of system significantly.
2, the utility model has been owing to fully phased out foam pump and collocation mechanism thereof, and is simple in structure, easy to maintenance, eliminated potential faults.
3, as if special circumstances such as appearance power failures, fire pump starts standby diesel oil fire pump and gets final product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises working line system and single-chip computer control system, a, working line system: comprise that water storage device 10 links to each other with fire pump 1 by discharge detector 3; The foam solution basin 8 that has valve 7 links to each other with foam solution flow detector 6 by electrically operated valve 5; Described foam solution flow detector 6 is arranged on the foam solution flow in pipes between discharge detector 3 and the fire pump 1; Described fire pump 1 links to each other with foam producer 9; Fire pump 1 links to each other with power supply; B, single-chip computer control system: comprise SCM system 4 respectively with electrically operated valve 5, foam solution flow detector 6 links to each other with discharge detector 3; Electrically operated valve 5 links to each other with power supply with SCM system 4.Described fire pump 1 is in parallel with diesel oil fire pump 2.
When using the utility model, at first start fire pump 1, and open by-pass valve control 7 on the foam solution basin 8, because the work of fire pump 1, discharge detector 3 is transferred to SCM system 4 with detected data on flows signal, after SCM system 4 receives signal, control electrically operated valve 5 is opened, foam solution flow detector 6 is started working and is detected data at this moment, and with detected transfer of data to SCM system 4, SCM system 4 is according to discharge detector 3 detected data on flows signals and foam solution flow detector 6 detected data-signals, utilize the opening degree of the mixed proportion control electrically operated valve 5 of SCM system 4 prior water of setting and foam, make the mixed proportion of system's fire water and foam solution reach requirement, 9 fire extinguishings of supplying foam generator are used; If special circumstances such as power failure occur, fire pump starts standby diesel oil fire pump 2 and gets final product.The injection rate of foam solution has marked the manual function control of the electrically operated valve 5 of scale by adjusting, can guarantee the fire-extinguishing function concurrently of system in any case.The injection phase of the utility model foam solution is arranged on the suction side of fire pump 1, directly suck by fire pump, do not use foam pump and collocation mechanism thereof, simplify the structure, reduced cost, owing to fully phased out foam pump and collocation mechanism thereof, simple in structure, easy to maintenance, eliminated potential faults.
