Description
Technical field
The utility model is a kind of gas distribution device, particularly a kind of gas distribution device that is used for gas water-heater.The renovation technique that belongs to gas distribution device.
Background technique
The gas distribution device that used airtight exhausting formula burner is adopted on the present common forced-ventilated gas water heater has only a blast tube, whole burners are all in burning during water heater working, its minimum thermal load is all monolithic burner minimum thermal load sums, total heat duties is bigger, minimal temperature rise is higher, and the user is the water-exit temperature height when using summer.In addition, because but the heat load scope of the smooth combustion of monolithic burner is smaller, when whole monolithic burners during, combustion condition instability, occur easily that wind loading rating is poor, tempering, take off fire etc. and influence the water heater poor combustion operating mode in working life with its minimum thermal load operation.
The model utility content
The purpose of this utility model is to consider the problems referred to above and a kind of quantity that can regulate the monolithic burner that participates in burning as the case may be is provided, can reduce the minimum thermal load of combustion gas tool, reduce lowest temperature rise, effectively solve the gas distribution device of the too boiling hot problem of water in summer.The utility model can improve the stability of gas water-heater in underrun, and is convenient and practical.
The technical solution of the utility model is: gas distribution device of the present utility model, include the gas valve main body, first blast tube that is arranged on the combustion gas main passage on the gas valve main body and is communicated with the combustion gas main passage, wherein first blast tube is provided with the through hole that is communicated with the monolithic burner, wherein also being provided with at least one on the gas valve main body independently is provided with, second blast tube that directly is not communicated with first blast tube, also be provided with the through hole that is communicated with the monolithic burner on second blast tube, second blast tube is connected by the 4th blast tube with the combustion gas main passage, is provided with the control valve that switches on and off that can control second blast tube and combustion gas main passage between the 4th blast tube and the combustion gas main passage.
Above-mentioned first blast tube is connected with the combustion gas main passage by the 3rd blast tube.
The quantity of the through hole that is communicated with the monolithic burner that the quantity of the through hole that is communicated with the monolithic burner that above-mentioned first blast tube is provided with is provided with second blast tube is unequal.
Above-mentioned control valve is the self-priming solenoid valve.
The utility model is owing to adopt the gas valve main body to be provided with at least two independently of one another settings, the structure of the blast tube that directly is communicated with not, all be provided with the through hole that is communicated with the monolithic burner on the blast tube, and wherein be provided with the structure of the control valve that switches on and off that can control this blast tube and combustion gas main passage between at least one blast tube and the combustion gas main passage, the quantity of the blast tube of connecting by control valve may command and combustion gas main passage, the instant heating hydrophone can be regulated the quantity of the monolithic burner that participates in burning as the case may be, therefore, the utility model can reduce the minimum thermal load of gas water-heater, reduce lowest temperature rise, effectively solve the too boiling hot problem of water in summer.Improve the stability of gas water-heater simultaneously in underrun.The utility model is that a kind of design is ingenious, function admirable, convenient and practical gas distribution device.

Arrow is represented the combustion gas circulating direction among the figure.
Embodiment
Below in conjunction with accompanying drawing and concrete true mode the utility model is described further.
Structural representation of the present utility model such as Fig. 1, shown in 2, include gas valve main body 1, be arranged on combustion gas main passage 2 on the gas valve main body 1 and first blast tube 5 that is communicated with combustion gas main passage 2, wherein first blast tube 5 is provided with the through hole 7 that is communicated with the monolithic burner, wherein also being provided with at least one on the gas valve main body 1 independently is provided with, second blast tube 6 that directly is not communicated with first blast tube 5, also be provided with the through hole 9 that is communicated with the monolithic burner on second blast tube 6, second blast tube 6 is connected by the 4th blast tube 4 with combustion gas main passage 2, is provided with the control valve that switches on and off 8 that can control second blast tube 6 and combustion gas main passage 2 between the 4th blast tube 4 and the combustion gas main passage 2.
Above-mentioned first blast tube 5 is connected with combustion gas main passage 2 by the 3rd blast tube 3.
The quantity of above-mentioned first blast tube, 5 through holes 7 that are communicated with the monolithic burner that be provided with is unequal with the quantity of second blast tube, 6 through holes 9 that are communicated with the monolithic burner that be provided with.
In the present embodiment, above-mentioned control valve 8 is the self-priming solenoid valve.
Working principle of the present utility model is as follows: when control valve 8 was closed, as shown in Figure 1, combustion gas entered first blast tube 5 through combustion gas main passage 2, from through hole 7 ejections, because control valve 8 has been blocked the 4th blast tube 4, so do not have combustion gas in second blast tube 6.This state is used for using summer gas water-heater, and this state can transfer to gas water-heater the minimum thermal load.
When control valve 8 is opened, as shown in Figure 2, combustion gas this moment enters first blast tube 5 by combustion gas main passage 2, part combustion gas is from through hole 7 ejections, simultaneously because control valve 8 unlatchings, part combustion gas can enter second blast tube 6 by the 4th blast tube 4, and this state is used for using winter gas water-heater, and this state can transfer to maximum heating load with gas water-heater.
