Abstract
The utility model discloses a metering-type proportional mixing device of injected foam, which comprises a motor, a foam liquid storage container and a flow meter. An electrical control frame is connected with the flow meter through a circuit; the motor is connected with a foam liquid pump through a coupling; the foam liquid storage container is connected with a mixer through a steel pipe; and a gate valve is installed in the middle thereof. The utility model has the advantages that the metering-type proportional mixing device which can inject a foam liquid into a firefighting trunk line according to set proportion; through the device, not only the mixing proportion of the liquid is more accurate in the actual firefighting process, but also a great amount of foam liquid is saved; the flow range is large; and the foam liquid can be added at any time in the firefighting process.
Description
Technical field:
The utility model relates to a kind of metering-type and injects foam proportioning unit, is specially adapted to use on the fire-fighting fire extinguishing engineering.
Background technology:
Existing foam fire-fighting design library part editor and reuse mainly contains two kinds, the one, the pressure type foam proportioning unit, moreover be and the balanced type foam proportioning unit, the pressure type foam proportioning unit exists range of flow little, defectives such as the foam liquid tank volume is little, the balanced type foam proportioning unit exists metering inaccurate, shortcomings such as foam solution waste.
Summary of the invention:
Task of the present utility model is to propose a kind of metering-type to inject foam proportioning unit, not only can save a large amount of foam solutions, and range of flow is big, and can replenishes foam solution at any time.Task of the present utility model is finished like this, metering-type injects foam proportioning unit, it comprises motor, foam liquid tank, flowmeter is characterized in that: automatically controlled frame and flowmeter are connected by circuit, and motor is connected by clutch with foam pump, connect the middle gate valve of installing between foam liquid tank and the blender by steel pipe.The utlity model has following effect: the utility model provides a kind of metering-type injection foam proportioning unit that injects foam solution in the ratio of setting to the fire chief line, this device not only makes the foam solution mixed proportion more accurate in actual fire-fighting process, and can save a large amount of foam solutions, and range of flow is big, also can replenish foam solution at any time in the fire-fighting course of battle.
Description of drawings:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the connecting line schematic diagram of the utility model device.
Drawing explanation: 1, gate valve, 2, feed tube, 3, foam pump, 4, drain pipe, 5, motor, 6, flowmeter, 7, proportioner, 8, go out the mixed liquor pipe, 9, underframe, 10, the foam solution storage tank, 11, flexible connecting pipe, 12, check valve, 13, check-valves, 14, automatically controlled frame.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing; motor is by being bolted on the underframe 9; two on motor (or diesel engine); when main frame has problem not work; can be converted to stand-by pump by controller chassis; the output shaft of motor 5 is connected by roller with the output shaft of foam pump 3; gate valve 1 usefulness flange directly connects the feed tube 2 of foam pump 3; foam pump 3 connects feed tube 2 by flange; the other end connects drain pipe 4; drain pipe connects check-valves 13 by flange; check-valves other end connection traffic meter 6; flowmeter connects proportioner 7 by flange; nozzle is arranged on the proportioner; can form a negative pressuren zone; foam solution is gone in the mixed liquor pipe 8 through liquid outlet; concentrated tank 10 is to be connected by steel pipe type flexible connecting pipe 11 with proportioner; automatically controlled frame 14 is connected by circuit with flowmeter; foam solution in the foam tank; through gate valve; feed tube reaches foam pump; after after the foam pump pressurization, through check valve 12; drain pipe; flowmeter injects the fire chief line, wherein; gate valve is convenient to maintenance and installation; check valve on the drain pipe mainly is to prevent the aqueous reflux on the fire chief line when termination of pumping, and the main effect of flowmeter is the flow that detects foam solution, so that switch board is proofreaied and correct the rotating speed of foam pump immediately; supply with foam solution by certain flow, guarantee the accurate by a certain percentage proportioning of mixed liquor.
