FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: 1. a water inlet pipe; 2. an electromagnetic valve; 3. a water tank; 31. a cold water zone; 32. a hot water zone; 4. a water temperature meter; 5. a liquid level gauge; 6. a heat exchange circulating pump; 7. a water supplementing pump; 8. a water supplementing pipe; 9. a boiler body; 10. a heat exchanger; 11. a partition plate.
Detailed Description
Referring to fig. 1, the embodiment is an energy-saving gas boiler, comprising a boiler body 9, a heat exchanger 10 is installed at a smoke outlet of the boiler body 9, a water tank 3 is arranged outside the boiler body 9, a partition plate 11 is arranged in the water tank 3, the partition plate 11 divides the water tank 3 into a cold water area 31 and a hot water area 32, a water outlet at the bottom of the cold water area 31 is connected with a heat exchange circulating pump 6, a water pipe entering the heat exchanger 10 is arranged at an output end of the heat exchange circulating pump 6, and the water pipe extends out of the heat exchanger 10 and returns to the hot water area 32 of the water tank 3; the water outlet at the bottom of the hot water area 32 is connected with a water supplementing pump 7, and the output end of the water supplementing pump 7 is provided with a water supplementing pipe 8 connected to the water inlet of the boiler body 9.
Furthermore, the heat exchange circulating pump 6 is provided with two centrifugal pumps M1 in parallel, one for each standby, and the water supplementing pump 7 is provided with two high-temperature multistage centrifugal pumps M2 in parallel, one for each standby.
Further, the hot water area 32 is provided with a liquid level meter 5 and a water temperature meter 4, a water inlet pipe 1 is arranged above the cold water area 31, an electromagnetic valve 2 is arranged on the water inlet pipe 1, and the liquid level meter 5 is in signal connection with the electromagnetic valve 2; the liquid level meter 5 is interlocked with the electromagnetic valve 2 of the water inlet pipe 1 and an alarm in an operation room, so that when the water level is too high, the water inlet is closed to prevent overflow, when the water level is too low, the alarm is triggered to alarm, and the multistage centrifugal pump M2 is manually interfered to start and stop, so that equipment damage caused by the suction of the multistage centrifugal pump M2 is prevented.
