Description
Technical field
The utility model relates to a kind of proportion mixer, especially a kind of malleation measurement injecting type proportion mixing device.
Background technology
In recent years, fire hazard situation both domestic and external was more and more severeer, and super-huge fire in rapid succession, loses huge.In the face of this situation, each country all has higher requirement to extinguishing device and fire-extinguishing apparatus.The foam proportioning unit that generally uses is mainly by two kinds now: a kind of is the pressure type foam proportioning unit, and another kind is the balanced type foam proportioning unit.The shortcoming of both's various degrees:
1. pressure type foam proportioning unit range of flow is little, capsule damages easily, the foam liquid tank volume is little, pressure window manufacturing expense height.
2. the balanced type foam proportioning unit exists ratio inaccurate, shortcomings such as foam solution waste can only be from experimentally drawing the mixing ratio of foam with sense organ, and can not precise quantification, how much do not can say mixing ratio at the scene, only know by such adjusting to access foam mixing liquid.
The utility model content
Technical problem to be solved in the utility model is, overcome problems of the prior art, needed a kind of malleation measurement injecting type proportion mixing device that accurate foam solution mixing ratio can be provided in the foam fire-fighting engineering is provided, improved at the foam proportioning unit that generally uses, aimed to provide a kind of proportion mixer that accurate foam solution mixing ratio is provided.
In order to address the above problem know-why of the present utility model is such:
The malleation measurement injecting type proportion mixing device comprises foam solution pipeline and fire chief road, and the foam solution pipeline is connected with the fire chief road, it is characterized in that:
The foam solution pipeline is provided with the flowmeter of measuring the foam solution flow, and the fire chief road is provided with the flowmeter of measuring discharge;
The foam solution pipeline is connected a concentrated tank by a gear pump with pipeline, gear pump also connects a return line, and return line is communicated with concentrated tank, and return line is provided with magnetic valve; Described concentrated tank, gear pump, magnetic valve constitute the closed circuit of foam solution by pipeline;
Flowmeter, the flowmeter on the fire chief road on the described foam solution pipeline connect a controller together, and controller connects the magnetic valve on the return line.
Described controller is the PLC programmable logic controller (PLC).
Described magnetic valve is 4-20mA or 0-1mA Current Control magnetic valve.
Described gear pump is the gear type displacement pump, and the gear type displacement pump connects a drive motors.
Beneficial effect, a kind of malleation measurement injecting type proportion mixing device of the present utility model, what adopt is that control foam solution capacity of returns is controlled the foam solution quantity delivered indirectly, because concentrated tank, flowermeter, return line, gear pump, motor, magnetic valve, the design of PLC programmable logic controller (PLC), by being arranged on the flowermeter on foam solution pipeline and the fire chief line, the PLC programmable logic controller (PLC) calculates fire chief way outlet actual mixture ratio in real time, and the demand mixing ratio set of user relatively simultaneously, by the switch degree of control electrically-controlled valve, thereby change the foam solution quantity delivered indirectly, be able to provide the effect of foam solution mixing ratio accurately.This has designed owing to digitized processing actual foam solution mixing ratio, makes the foam solution mixing ratio that obtains more accurate, and extinguishing property improves greatly, has avoided the waste of foam solution simultaneously.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a malleation measurement injecting type proportion mixing device system principle schematic diagram described in the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1
Concentrated tank 1 connects gear pump 2 by management, and gear pump 2 connects magnetic valve 3 by return line, and magnetic valve 3 connects concentrated tank 1 by pipeline.Described concentrated tank 1, gear pump 2, magnetic valve 3 constitute the closed circuit of foam solution by pipeline.Magnetic valve 3 is 4-20mA or 0-1mA Current Control magnetic valve.Described gear pump 2 is the gear type displacement pump, and the gear type displacement pump connects a drive motors 7.
The described malleation measurement injecting type proportion mixing device of present embodiment: rely on the flowermeter on foam solution pipeline and the fire chief line, gather the flow size of two pipelines, can be according to the required foam solution mixing ratio that designs in advance, the switch degree of magnetic valve on the control return line, the foam solution mixing ratio of coming dynamic adjustments fire chief road.
When the flowermeter on being arranged on foam solution pipeline and fire chief line has obtained flow number on foam solution pipeline and the Trunk Line, by the output cable flow information is passed to the PLC programmable logic controller (PLC), process PLC converses the actual mixture ratio of Trunk Line upper outlet foam solution, shows by LED display.Simultaneously, the PLC programmable logic controller (PLC) is provided with user's input window, can be needed foam solution mixing ratio input PLC.Like this, the PLC programmable logic controller (PLC) can compare the actual mixture ratio numerical value of user's request mixing ratio and Trunk Line upper outlet foam solution, and controls the switch degree of magnetic valve on the return line by cable.Control foam solution capacity of returns, thereby controlled the foam liquid measure that the foam solution pipeline is supplied with indirectly, when the actual mixture ratio of user's request mixing ratio and Trunk Line upper outlet foam solution is identical, it is motionless that PLC PLC controls magnetic valve keeps, the foam ratio system reaches stable, exports foam solution mixing ratio accurately.This system can be along with the different flow of Trunk Line, provide corresponding foam liquid measure according to the mixing ratio numerical value that the user imported, thereby obtain more accurate foam solution mixing ratio, this has designed owing to digitized processing actual foam solution mixing ratio, show more directly perceived, the foam solution mixing ratio that obtains is more accurate, and extinguishing property improves greatly, has avoided the waste of foam solution simultaneously.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
