Pipeline is connected, and the other end is connected with second water pipe.
Further, second water pipe is divided into left part and right part using check valve present position as line of demarcation,
The junction of second water pipe and third water pipe is located at the right part of second water pipe.
Further, second water pipe may be provided with second solenoid valve.
Further, the second solenoid valve is in junction and the check valve of the second water pipe and third water pipe
Between.
The utility model makes the water in the second water pipe can by the break-make of the first solenoid valve control third water pipe
It flows back into the first water pipe, and then small pump is made also can intermittently to supply water always in opening for inside of boiler, in this way
The service life of small pump is delayed, greatly reduces small pump start-stop time, reducing the coil heating time indirectly reduces
Small pump start and stop moment is interfered caused by power grid, meanwhile, moisturizing is sensitiveer.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
Embodiment 1
Please refer to Fig. 1, a kind of boiler interval make-up water supply control system of the utility model, including water tank 100, more water service pipes
Road, small pump 200, check valve 300,400 and first solenoid valve 800 of inside of boiler.
Water tank 100；The water tank 100 is used for storing for future use water；
More water pipes；Including the first water pipe 500, the second water pipe 600 and third water pipe 700；It is more
A water pipe may also include other water pipes, such as the 4th water pipe, the 5th water pipe etc..
Small pump 200；The small pump 200 is connected by the first water pipe 500 with the water tank 100；The benefit
Water pump 200 is used to extract the spare water in water tank 100.
Check valve 300；The check valve 300 is arranged on the second water pipe 600；It is described to be used to prevent inside of boiler
Water is flowed out from the second water pipe 600 in 400, to water is fed in inside of boiler 400 by small pump 200, second
Hydraulic pressure in water pipe 600 need to reach certain value, and the small pump 200 just can enter boiler by the second water pipe 600
In liner 400.
Inside of boiler 400；The inside of boiler 400 is connected by the second water pipe 600 with the small pump 200；Pot
Furnace internal-lining 400 is used for the water in heating inner liner.
First solenoid valve 800；Be arranged on third water pipe 700, one end of the third water pipe 700 with it is described
First water pipe 500 is connected, and the other end is connected with second water pipe 600, and water is controlled by the first solenoid valve 800
Break-make in third water pipe 700, when the first solenoid valve 800 obtains electric, the first solenoid valve 800 blocks water in third water service pipe
It circulates in road 700；Alternatively, during the first 800 dead electricity of solenoid valve, the first solenoid valve 800 blocks water to circulate in third water pipe.
Second water pipe 600 is divided into left part and right part using 300 present position of check valve as line of demarcation, described
The connecting interface of second water pipe 600 and third water pipe is located at the right part of second water pipe 600.
The boiler interval make-up water supply control system moisturizing process：The small pump 200 is always in opening, small pump
Spare water in 200 extraction water tanks 100 is flow to through the second water pipe 600 in inside of boiler 400, when in inside of boiler 400
Water it is enough or water has had arrived at predetermined amount；At this point, not needing to moisturizing in inside of boiler 400, therefore to stop supplying
Water to allow the open and close (since it is desired that interval moisturizing) of small pump 200 infrequently, passes through and controls the first solenoid valve 800
Third water pipe can be with water flowing, and the water of the right part entered in the second water pipe 600 in this way flows back into the first water pipe
In 500, check valve 300 needs certain hydraulic pressure water can be allowed to pass through, and therefore, the water that small pump 200 extracts at this time will not flow to
In inside of boiler 400.
When needing to supply water for inside of boiler 400 again, third water pipe is controlled to make it can not by the first solenoid valve 800
Water flowing, the hydraulic pressure increase in the second water pipe 600, water are flowed by check valve 300 in inside of boiler 400.
Small pump 200 can not close, open and can intermittently supply water for inside of boiler 400 in this way.
Embodiment 2
With 1 difference of embodiment, the boiler interval make-up water supply control system is additionally provided with second solenoid valve.
Second water pipe 600 may be provided with second solenoid valve, and the second solenoid valve is in the second water pipe
Between 600 and the connecting interface of third water pipe and check valve 300.
The break-make of the second water pipe 600 is controlled by second solenoid valve, eliminates the reliance on only rely only on check valve 300 in this way
Control the break-make of the second water pipe 600.By 800 third water pipe of the first solenoid valve can water flowing when, described second
The second water pipe of solenoid valve control 600 can not water flowing.By second solenoid valve third water pipe can not water flowing when, institute
Stating second solenoid valve controls the second water pipe 600 can water flowing.
Also water passing switch can be set to replace second solenoid valve in inside of boiler 400.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
