Abstract
The utility model relates to a novel gas dual-purpose boiler for heating and hot-water. The water used for heating is heated by a heat exchanger (8) and circulates through a water circulating pump (3), and the domestic water is heated by a plate exchanger (4). In order to preventing that the iron rust and the impurity enter the pipelines in the boiler and causes the clogging, the utility model adds a magnetic filter device (1) between a heating return pipe (25) and a water circulating pump (3); the iron rust in the water is adsorbed by an axial magnet (27); the impurity in the water is filtered by a filter screen (26). The experiment proves that the utility model can effectively prevent that the iron rust and the impurity in the water enter the pipelines in the boiler, the flow quantity of the heating hot-water and the thermal efficiency of the boiler are increased, the durability of the boiler is increased, and the failure rate is reduced. The utility model also has the advantages of compact conformation, safe and reliable operation, convenient use and repairing, etc.
Description
(1) technical field
The utility model belongs to domestic gas-fired water heater, especially a kind of wall-hanging gas-heating/hot water two purpose boiler.
(2) background technology
The use of gas-heating/hot water two purpose boiler is that heat abstractor is connected on the entery and delivery port of gas-heating/hot water two purpose boiler by water pipe at present, accelerates hot water circuit by water circulating pump, reaches the purpose of heating heat radiation.But because heat abstractor and water pipe mostly are cast iron or ironwork, contact the back with water and produce a large amount of iron rust, and boiler also can be brought some impurity into when installation and daily use moisturizing, after iron rust and impurity are recycled water pump and suck the boiler internal pipeline, will blocking pipeline, this brings very big influence to whole heat circulating system.Show that mainly the heating hot water flow reduces, heat exchange capability of heat exchanger descends, thereby the thermal efficiency and the service life of having reduced boiler the fault of boiler is increased, and gives daily use and maintenance is made troubles.
(3) summary of the invention
The utility model is exactly a kind of novel gas heating/hot water two purpose boiler that proposes at the problems referred to above.In order to address the above problem, the utility model connects a magnetic filter device at boiler water inlet place.Like this, when water circulating pump sucked water in boiler, iron rust in the water and impurity just were filtered in filter, can't enter in the boiler internal pipeline.Effectively prevented pipeline blockage, improved the heating hot water flow, improved boiler thermal output and service life, reduced the purpose of fault rate thereby reach.
(4) description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is A-A sectional view (amplification);
(5) specific embodiment
As shown in Figure 1, the utility model is by magnetic filter device 1; partial circulating water pipe 2; water circulating pump 3; plate type heat exchanger 4; water flow switch 5; burner 6; combustion chamber 7; heat exchanger 8; automatic exhaust steam valve 9; controller 10; blower fan 11; blast detecting element 12; over-temperature protection element 13; gas nozzle 14; demarcation strip 15; electronic commutation triple valve 16; gas ratio valve 17; housing 18; gas inlet pipe 19; heating outlet pipe 20; domestic hot-water's outlet pipe 21; NTC temperature element 22; life cold water oral siphon 23; discharge detecting element 24; heating return pipe 25 compositions such as grade.
During work, for needs heating water, backwater enters heat exchanger 8 by heating return pipe 25 through magnetic filter device 1, water circulating pump 3, water flow switch 5.Combustion gas enters in the burner 6 through gas inlet pipe 19 gas ratio valves 17 and gas nozzle 14, burning in combustion chamber 7, and open by 8 pairs of water heating of heat exchanger, hot water is flowed out by heating outlet pipe 20 through pipeline and electronic commutation triple valve 16, uses for heating.Be the air in the discharge system, automatic exhaust steam valve 9 be housed in the pipeline upper end.Electronic commutation triple valve 16 other ends communicate with plate type heat exchanger 4, when the heating of closing electric T-shaped valve 16 with water passage and when opening the path that connects plate type heat exchanger 4, flow of hot water is gone into board-like heat exchanger 4, the cold water that enters in the plate type heat exchanger 4 through life cold water oral siphon 23 and discharge detecting element 24 is heated, cold water is heated after domestic hot-water's outlet pipe 21 flows out, and uses for life.As depicted in figs. 1 and 2, enter in the boiler pipe, between heating return pipe 25 and water circulating pump 3, installed magnetic filter device 1 additional in order to prevent iron rust and impurity.Screen pack 26 and bar magnet 27 are installed in the magnetic filter device.When water circulating pump 3 absorbed water in system, the iron rust in the water can be attracted on the bar magnet 27, and impurity can be filtered net 26 and filter in filter.After using a period of time, screw off enclosing cover 28, take out bar magnet 27 and screen pack 26 iron rust and impurity are washed.Reload and continue in the magnetic filter device 1 to use.Thereby effectively prevented the boiler internal pipeline blockage, improved the thermal efficiency and the service life of boiler, reduced fault rate.The work operation of the whole boiler of controller 10 controls.Package unit is contained in the housing 18, and with demarcation strip 15 with water circuit system and combustion system is airtight separates.By blower fan 11 and blast detecting element 12 burnt gas is discharged machine.
The utility model also has compact conformation, and is safe and reliable to operation, characteristics such as easy to use and maintenance.
