Abstract
The utility model relates to a firefighting extinguishing technology, and discloses an automatic foam proportioner. The automatic foam proportioner comprises a mixer as well as a water inlet pipeline and a foam liquid pipeline entering the proportioner, and is characterized in that the water inlet pipeline is provided with a water meter; the end part of the foam liquid pipeline is connected with a foam liquid tank; the foam pipeline from the foam liquid tank to the proportioner is successively provided with a foam output range regulating valve, a foam flow meter and a variable frequency pump; the output ends of the water meter and the foam flow meter are connected with a controller; and the output end of the controller is connected with the variable frequency pump. The inlet flow measured by using the water flow and the foam flow measured by using the foam flow meter are input to the controller, the variable frequency pump is controlled by the controller on the basis of the inlet flow to regulate the foam flow, so that the mixing ratio of the inflow to the foam liquid is stable.
Description
Technical field
The utility model relates to the fire-fighting fire extinguishing technology, particularly a kind of full-automatic foam proportion mixer.
Background technology
At present, pressure type foam proportioning unit commonly used is comprised of foam tank, capsule, foam proportioner, water inlet pipe, safety valve, check-valves etc., when pressure flow process foam proportioner, foam proportioner is shunted it in proportion, wherein sub-fraction water enters the foam tank interlayer with capsule, and the extruding capsule can make water mix with foam solution, the foam mixing liquid of output is put out a fire thereby form airfoam for to the spraying equipment that produces foam.But in this type of foam proportioning unit, foam solution and press water mixing ratio change fluctuation greatly with pressure, and the inlet pressure of foam solution inlet pressure and water can not keep constant pressure reduction, the mixing ratio poor stability.
Summary of the invention
The purpose of this utility model is to provide a kind of full-automatic foam proportion mixer, utilize water ga(u)ge to detect flow of inlet water, the foam flowmeter detects the foam solution flow and is input to controller, controller is take flow of inlet water as benchmark, controls variable frequency pump and adjusts the flow of foam solution and make into the mixed proportion of water and foam solution and reach stable.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of full-automatic foam proportion mixer, the inlet pipeline and the foam solution pipeline that comprise blender and enter blender, it is characterized in that, be provided with water ga(u)ge in described inlet pipeline, the end of described foam solution pipeline is connected with the foam solution case, be provided with successively foam volume range regulation valve, foam flowmeter and variable frequency pump foam line from the foam solution case to blender, the output of described water ga(u)ge and foam flowmeter is connected with controller, and the output of described controller is connected with described variable frequency pump.
Characteristics of the present utility model and further the improvement are:
Be provided with between described variable frequency pump and described blender and make foam solution enter the check valve of blender from variable frequency pump.
Full-automatic foam proportion mixer of the present utility model, be provided with water ga(u)ge in inlet pipeline, the end of foam solution pipeline is connected with the foam solution case, be provided with successively foam volume range regulation valve, foam flowmeter and variable frequency pump foam line from the foam solution case to blender, the output of water ga(u)ge and foam flowmeter is connected with controller, and the output of controller is connected with variable frequency pump.Utilize water ga(u)ge to detect flow of inlet water, the foam flowmeter detects the foam solution flow and is input to controller, and controller is controlled variable frequency pump and adjusted the foam flow take flow of inlet water as benchmark, makes into the mixed proportion of water and foam solution to reach stable.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structure principle chart of full-automatic foam proportion mixer of the present utility model.
In figure: 1, foam volume range regulation valve; 2, check valve.
The specific embodiment
With reference to Fig. 1, be the structure principle chart of full-automatic foam proportion mixer of the present utility model.Wherein, be provided with water ga(u)ge in inlet pipeline, the end of foam solution pipeline is connected with the foam solution case, be provided with successively foam volume range regulation valve 1, foam flowmeter and variable frequency pump foam line from the foam solution case to blender, the output of water ga(u)ge and foam flowmeter is connected with controller, and the output of controller is connected with variable frequency pump.The variable frequency pump operating pressure is large, guarantees to enter the foam solution pressure of blender all the time greater than the pressure of intaking.Be provided with between variable frequency pump and blender and make foam solution enter the check valve 2 of blender from variable frequency pump, check valve 2 can avoid press water to blow back in the foam solution pipeline.
Full-automatic foam proportion mixer of the present utility model, utilize water ga(u)ge to detect flow of inlet water, the foam flowmeter detects the foam solution flow and is input to controller, controller is take flow of inlet water as benchmark, through the computing output current signal, enter the foam solution flow of blender according to the rotating speed adjustment of size of current adjusting variable frequency pump, reach stable thereby make into the mixed proportion of water and foam solution.Another characteristics of the present utility model are can regulate by controller the ratio of water inlet and foam solution, and guarantee the stability of preset proportion.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that do not break away from the scope that the utility model claim is protected, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
