The feed flow module is 1 or more, is connected side by side with defeated turn of pump of foam solution.
Preferably, the anti-frothing foam liquid conveying equipment of above-described multichannel, the supplying valve are band position
The hand-operated valve of feedback.
Preferably, the anti-frothing foam liquid conveying equipment of above-described multichannel, the position of the liquid-level switch
Higher than the inlet of imbibition pipe end.
The basic principle of the anti-frothing foam liquid conveying equipment of multichannel described in the utility model is: foam solution is defeated by foam solution
Turn pumping suction, is gone in concentrated tank by foam solution bucket is defeated；Imbibition module and feed flow module have vacuumizing function and using anti-
Air inlet design, prevents air from entering pipeline.
Following mechanism can avoid air and be mixed into foam solution:
1, the anti-air inlet mechanism of imbibition module:
1), each foam solution is defeated transfers to industry for the first time when using foam solution conveying equipment, and pipette is inserted into foam solution bucket
In, liquid sucting valve is closed, detection confirmation liquid-level switch state is to have liquid, opens the first vacuum generator, applies negative pressure to pipette；
When the first vacuum transducer pressure reaches setting value, pipette fills with liquid, turns off the true of the first vacuum generator
Empty valve opens liquid sucting valve, starts defeated turn of foam solution pump, that is, can avoid circuit air and enter foam pump；
2) when liquid level is lower than liquid-level switch in foam solution bucket, liquid-level switch state is switched to aneroid, certainly by controller
It is dynamic to close liquid sucting valve, avoid air from sucking；
3), after having aspirated the suction of foam solution bucket, pipette need to be smoked in another foam solution bucket of insertion into
Row suction；When foam solution rifle is smoked, liquid sucting valve is closed, and is closed with defeated turn of pump interface channel of foam solution, and negative pressure disappears in pipette,
First closed check valve retains foam solution in pipette, avoids sucking air when aspirating next barrel of foam solution.

1), each foam solution is defeated transfers to industry for the first time when using foam solution conveying equipment, closes supplying valve, it is true to open second
Empty generator applies negative pressure to liquid supply pipe；When the second vacuum transducer pressure reaches setting value, feed flow inner air tube is with basic
It takes out to the greatest extent, turns off the vacuum valve of the second vacuum generator, open supplying valve, start defeated turn of foam solution pump, that is, can avoid liquid supply pipe
Road air enters foam pump；
2), after first concentrated tank filling is full, liquid supply pipe need to be smoked and is filled in another concentrated tank of insertion；
When liquid supply pipe is smoked, supplying valve is closed, the interface channel pumped with defeated turn of foam solution is closed, and imbibition pipe pressure disappears, liquid supply pipe end
End second one-way valve is closed (this check valve needs to open under a certain pressure), is retained foam solution in liquid supply pipe, is avoided right
Enter air when next concentrated tank fills in liquid supply pipe.
When the anti-frothing foam liquid conveying equipment of multichannel works, the defeated pump operation that turns of foam solution passes through controller control, controller
The signal of each valve, each sensor is detected, determines the operating status of defeated turn of foam solution pump.
The anti-frothing foam liquid conveying equipment of multichannel described in the utility model, foam solution source are not limited to foam solution bucket, can also

It is also possible to other containers, such as large capacity foam solution bucket, foam liquid pool, fixed foam liquid tank；Feed liquid way is also unlimited
It is filled in being intubated from container top, can also be taken over and be filled by foam liquid container inlet.
The utility model has the advantages that the anti-frothing foam liquid conveying equipment of multichannel described in the utility model compared to the prior art have with
Lower advantage:
1, the anti-frothing foam liquid conveying equipment of multichannel provided by the utility model, it is reasonable in design, it can entirely prevent
Air enters in infusion pipeline, avoid air enter in infusion pipeline mixed with foam solution after foam, can overcome the prior art without
The shortcomings that method fills fire fighting truck concentrated tank or other foam liquid containers；It is remarkably improved fire-fighting operation efficiency, high reliablity.
2, the present apparatus can realize that fire-fighting foams liquid multichannel aspirates multichannel feed flow, and each imbibition module, feed flow module can be grasped independently
Work implementation foam solution is defeated to transfer to industry, and integrated level is high, high reliablity.
3) pass through liquid feed valve, supplying valve and liquid-level switch state in detection pressure sensor and each module, and operation
The control that control handle realization pumps defeated turn of foam solution, high degree of automation, function admirable are easy to use.
