Description
The utility model relates to a kind of gas fired-boiler equipment, particularly relates to a kind of gas fired-boiler equipment with heating and heat supply water auto-conversion function.
Gas fired-boiler equipment has a wide range of applications industrial.Along with the raising of people's living standard, the gas fired-boiler equipment that is applied to average family has appearred planting particularly.This gas fired-boiler equipment generally is for user's heating, also is the user heat energy is provided.But for the purpose of easy to use, people need gas fired-boiler equipment to heat to the user, again can be to the user for non-drinking hot water.
Realize the gas fired-boiler equipment of a kind of prior art of this function, as shown in Figure 2, a kind of typical home has the gas fired-boiler of heating and heat supply water auto-conversion function.This gas fired-boiler equipment comprises: running water water inlet 1, and this running water water inlet 1 links to each other with the tap water supply system (not shown); Running water water inlet 1 is connected to circulating hot water heat exchanger 3 by tap water pipeline 11, and this tap water pipeline 11 is connected to hot water outlet 12 after passing this circulating hot water heat exchanger 3, and the hot water that flows out from hot water outlet 12 uses for the user.Circulating hot water heat exchanger 3 also links to each other with the pipeloop 13 of this gas fired-boiler equipment, is full of the circulating hot water from this pipeloop 13 in circulating hot water heat exchanger 3, and these circulating hot waters heat the running water in the tap water pipeline 11.Also connect magnetic switch 4 on tap water pipeline 11, this magnetic switch is connected to two position three-way valve 5 by electric controller 2, and the pipeloop 14 that is connected on the circulating hot water heat exchanger 3 also is connected to this two position three-way valve 5.Have in the heating and the gas fired-boiler equipment of heat supply water auto-conversion function at this and also to comprise water circulating pump 6, be used for keeping circulating hot water to circulate at this gas fired-boiler equipment.As shown in Figure 2,8 is gas heat exchanger among the figure, and this gas heat exchanger 8 is heat exchangers of a kind of routine, is heated by burner 7 combustion gas; And 10 be heating equipment, for example radiator, steam heating pipe or the like.Also has hot-water valve 9 at hot water outlet.
This gas fired-boiler equipment with heating and heat supply water auto-conversion function comprises heating state and heat supply water state.At the heating state, this gas fired-boiler equipment with heating and heat supply water auto-conversion function just heats to the user; And at the heat supply water state, this gas fired-boiler equipment with heating and heat supply water auto-conversion function is just to user's heat supply water.
At the heating state, the hot-water valve 9 of this system is closed, and two position three-way valve 5 makes pipeloop 15 be communicated with pipeloop 16 simultaneously, and this pipeloop 15 is not communicated with pipeloop 14.In this case, rely on the effect of water circulating pump 6, circulating hot water is shown in the arrow among Fig. 2, along water circulating pump 6 → gas heat exchanger 8 → two position three-way valve 5 → heating equipment 10 → water circulating pump 6, so move in circles, this gas fired-boiler equipment with heating and heat supply water auto-conversion function provides heat energy for the user; In pipeloop 14 and 13, there be not simultaneously flowing of circulating hot water.
Need provide for the user under the situation of hot water, the gas fired-boiler equipment that this must be had heating and heat supply water auto-conversion function switches to the heat supply water state.At first open hot-water valve 9, then hot water flows out from hot water outlet 12, and the running water in tap water pipeline 11 just passes circulating hot water heat exchanger 3 from running water water inlet 10 and flows to hot water outlet 12 at this moment, flows thereby produced in tap water pipeline 11.This flowing in the tap water pipeline 11 makes magnetic switch 4 produce control signal, this control signal passes to electric controller 2,5 actions of electric controller 2 operation two position three-way valves, make pipeloop 15 be communicated with pipeloop 14, disconnect being connected of pipeloop 15 and pipeloop 16 simultaneously, make circulating hot water circulate along water circulating pump 6 → gas heat exchanger 8 → two position three-way valve 5 → circulating hot water heat exchanger 3 → water circulating pump, in heating equipment 10, then there is not the circulation of circulating hot water, thereby makes circulating hot water just flow by circulating hot water heat exchanger 3.By this method can be so that this gas fired-boiler equipment with heating and heat supply water auto-conversion function automatically switches to the heat supply water state from the heating state.Equally, after hot-water valve 9 is closed, because mobile being terminated in pipeloop 11, make magnetic switch 4 produce other control signal, this control signal passes to electric controller 2,5 actions of electric controller 2 operation two position three-way valves, make pipeloop 15 be communicated with pipeloop 16, close being connected of pipeloop 15 and pipeloop 14 simultaneously, thereby recover the circulation of water circulating pump 6 → gas heat exchanger 8 → two position three-way valve 5 → heating equipment 10 → water circulating pump 6, thereby this gas fired-boiler equipment with heating and heat supply water auto-conversion function is switched to the heating state from the heat supply water state.
But there are three shortcomings in this boiler plant: 1) owing to the heating to running water is to heat by circulating hot water heat exchanger 3, and circulating hot water heat exchanger 3 can distribute a large amount of heats in surrounding environment, has therefore caused unnecessary energy loss; 2) this boiler plant need use magnetic switch 4, controller 2, circulating hot water interchanger 3 and two position three-way valve 5 to come the heating state of boiler and the mutual switching of heat supply water state are controlled, thereby its cost is very high, is not suitable for promoting the use of in vast family; 3) complicated integral structure, difficult in maintenance.
The purpose of this utility model just provides a kind of simple in structure, cheap gas fired-boiler equipment with heating and heat supply water auto-conversion function.
