Description
Technical field
The utility model relates to a kind of fire-fighting equipments, and in particular to a kind of easy to use, fire-fighting operation is high-efficient, reliability
High anti-frothing foam liquid conveying equipment.
Background technique
Fire-fighting equipment is the indispensable facility when rescuing fire, and foam solution conveying equipment is generally defeated by pipette, foam solution
Turn pump, liquid supply pipe composition, effect is to extract foam solution from multiple foam solution buckets out, is transported to fire fighting truck concentrated tank or other
In foam liquid container.
The foam solution conveying equipment of the prior art, not anti-air inlet function, the air meeting after foam pump startup in pipette
Into in infusion pipeline, a large amount of foams are generated after mixing with foam solution, and mixed air needs 24 hours or more just in foam solution
It can largely be precipitated；Foam solution after above-mentioned foaming can occupy body after entering fire fighting truck concentrated tank or other foam liquid containers
Product, leads to not fill, and reduces fire-fighting operation efficiency, causes serious consequence.
Therefore, it is necessary on the basis of the prior art, R & D design one kind is reasonable in design, can solve existing
Technology bubble liquid conveying equipment it is defeated transfer to foam solution in industry be mixed into air cause foaming the problem of, be greatly improved fire-fighting operation
Efficiency, high reliablity, practical anti-frothing foam liquid conveying equipment.
Summary of the invention
Goal of the invention: purpose of the utility model is to solve the deficiencies in the prior art, provide a kind of structure design conjunction
Reason, can solve the problems, such as prior art foam solution conveying equipment it is defeated transfer to foam solution in industry be mixed into air cause foaming, can be big
It is big to improve fire-fighting operation efficiency, high reliablity, practical anti-frothing foam liquid conveying equipment.
Technical solution: in order to achieve the goal above, the technical solution that the utility model is taken are as follows:
A kind of anti-frothing foam liquid conveying equipment, it includes: that defeated turn of pump of foam solution, pipette, the first check valve, liquid level are opened
Pass, second one-way valve, supplying valve, exhaust valve, controller, power supply, control handle, liquid supply pipe, exhaust pipe, foam solution bucket and foam
Flow container；
Defeated turn of foam solution pump is connect by pipette with the first check valve, and pipette is inserted in foam solution bucket；
First check valve and liquid-level switch are arranged close to the position of imbibition pipe end, and the position of liquid-level switch is higher than imbibition pipe end
Inlet；Second one-way valve one end is connected by defeated turn of pump of pipeline and foam solution, and the second one-way valve other end is distinguished by pipeline
It is connected with supplying valve and exhaust valve；Feed flow valve outlet is connect with liquid supply pipe, and liquid supply pipe is inserted in concentrated tank；Exhaust valve and row
Tracheae is connected；Controller is connect with defeated turn of pump of foam solution, power supply, control handle, liquid-level switch and supplying valve respectively by cable.
The anti-frothing foam liquid conveying equipment, the supplying valve are the hand-operated valve with position feedback.
The basic principle of anti-frothing foam liquid conveying equipment of the present invention is: foam solution turns pumping by foam solution is defeated
It inhales, is gone in concentrated tank by foam solution bucket is defeated.
The utility model can avoid air in the following manner and be mixed into foam solution:
1, each foam solution is defeated transfers to industry for the first time when using foam solution conveying equipment, opens exhaust valve, closes supplying valve,
Exhaust valve after air drains in pipeline, will be turned off after exhaust valve, opens supplying valve and filled to concentrated tank, avoid circuit air
Into concentrated tank；
2, foam solution liquid level is gradually reduced in aspiration procedure, and when liquid level is lower than the position of liquid-level switch, liquid-level switch is issued
Low liquid level signal stops defeated turn of pump of foam solution, air is avoided to suck；
3, negative pressure disappears in pipette after termination of pumping, and the first closed check valve extracts pipette out, and air cannot be introduced into, pipe
It inside will be filled with foam solution, be inserted into another foam solution bucket and continue to aspirate, it is ensured that without air in pipette；
4, when being vented valve exhaust, supplying valve is in close state, and position signal controls defeated turn of foam solution by controller
Low-speed running is pumped, in favor of smooth exhaust；Exhaust finishes, and closes exhaust valve, opens supplying valve and fills to concentrated tank, Ke Yitong
Crossing the control of control handle, foam solution is defeated turns revolution speed to adjust filling speed, meets the needs of under different filling operating conditions.
The utility model has the advantages that anti-frothing foam liquid conveying equipment described in the utility model compared to the prior art have it is following excellent
Point:
Anti- frothing foam liquid conveying equipment provided by the utility model, it is reasonable in design, can entirely prevent air into
Enter in infusion pipeline, avoid air enter in infusion pipeline mixed with foam solution after foam, can overcome the prior art that can not make to disappear
The shortcomings that anti-vehicle concentrated tank or other foam liquid containers are filled；It is remarkably improved fire-fighting operation efficiency, high reliablity.
The utility model can be realized by detection supplying valve and liquid-level switch state and operating control handle to foam solution
The control of defeated turn of pump, high degree of automation, function admirable are easy to use.
