The utility model discloses when summer intake temperature is higher, only open a gas channel in first gas channel and the second gas channel through control valve control to can reduce gas heater's minimum heat load, reduce the minimum temperature rise, effectively solve the problem that summer water is too scalded, improve gas heater stability in the low-load operation simultaneously.
Description
Technical field
The utility model relates to the gas heater accessory, particularly a kind of gas distribution device that is used for gas heater.The renovation technique that belongs to gas distribution device
Background technology
The gas distribution device that used airtight exhausting formula burner is adopted on several automatic constant-temperature type gas heaters that rises higher at present 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 leaving water temperature height when using summer.In addition, because but the thermic load scope of the smooth combustion of monolithic burner is smaller, when whole monolithic burners during, combustion conditions instability, occur easily that wind loading rating is poor, tempering, take off fire etc. and influence the water heater inefficient combustion operating mode in service life with its minimum thermal load operation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of minimum thermal load that can reduce gas heater is provided, reduce lowest temperature rise, effectively solve the too boiling hot problem of water in summer, improve the gas distribution device that be used for gas heater of gas heater simultaneously in the stability of underrun.
The purpose of this utility model is achieved through the following technical solutions.
The utility model is used for the gas distribution device of gas heater, comprise the gas valve main body, the combustion gas main channel, first blast tube that is communicated with the combustion gas main channel, with disconnected second blast tube in combustion gas main channel, wherein be respectively equipped with the some through holes that are communicated with the monolithic burner on first blast tube and second blast tube, first blast tube and second blast tube are to independence, the opposite side of gas valve main body is provided with the 4th blast tube, first blast tube and the 4th blast tube are connected by the 3rd blast tube, second blast tube is connected by the 5th blast tube with the 4th blast tube, is provided with the control valve that switches on and off that can control the 4th blast tube and the 5th blast tube between the 4th blast tube and the 5th 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 combustion gas main channel is provided with gaseous-pressure and detects mouth.
Above-mentioned control valve is the self-priming magnetic valve.
The utility model is owing to adopt two relatively independent blast tubes, and the unequal structure of number of openings on two relatively independent blast tubes, in addition, one of them blast tube is communicated with the combustion gas main channel, the another one blast tube directly is not communicated with the combustion gas main channel, but control by other passages and control valve whether it open-minded, therefore, water heater 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 heater, reduces lowest temperature rise, effectively solves the too boiling hot problem of water in summer.Improve the stability of gas heater simultaneously in underrun.

The specific 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, comprise gas valve main body 1, combustion gas main channel 2, first blast tube 5 that is communicated with combustion gas main channel 2, with combustion gas main channel 2 disconnected second blast tubes 6, wherein be respectively equipped with the some through holes 4 that are communicated with the monolithic burner on first blast tube 5 and second blast tube 6, first blast tube 5 and second blast tube 6 are relatively independent, the opposite side of gas valve main body 1 is provided with the 4th blast tube 8, first blast tube 5 and the 4th blast tube 8 are connected by the 3rd blast tube 7, second blast tube 6 is connected by the 5th blast tube 10 with the 4th blast tube 8, is provided with the control valve that switches on and off 9 that can control the 4th blast tube 8 and the 5th blast tube 10 between the 4th blast tube 8 and the 5th blast tube 10.
In the present embodiment, the quantity of above-mentioned first blast tube, 5 through holes 4 that are communicated with the monolithic burner that be provided with is unequal with the quantity of second blast tube, 6 through holes 4 that are communicated with the monolithic burner that be provided with.
In the present embodiment, above-mentioned combustion gas main channel 2 is provided with gaseous-pressure and detects mouth 3.Because combustion gas main channel 2 is provided with gaseous-pressure and detects mouth 3, when producing water heater, can carry out secondary pressure and regulate according to the actual load needs.
In the present embodiment, above-mentioned control valve 9 is the self-priming magnetic valve.
During the utility model work, when control valve 9 was closed, as shown in Figure 1, combustion gas entered first blast tube 5 through combustion gas main channel 2, from through hole 4 ejections, because control valve 9 has been blocked the 5th blast tube 10, so do not have combustion gas in second blast tube 6.This state is used for using summer gas heater, and this state can transfer to gas heater the minimum thermal load.
When control valve 9 is opened, as shown in Figure 2, combustion gas this moment enters first blast tube 5 by combustion gas main channel 2, part combustion gas is from through hole 4 ejections, simultaneously because control valve 9 unlatchings, part combustion gas can enter second blast tube 6 by the 5th blast tube 10, and this state is used for using winter gas heater, and this state can transfer to maximum heating load with gas heater.
