Description

The automatic temperature regulator of gas hot-water apparatus

The utility model relates to a kind of temperature regulator.

At present; the general gas heater that uses is to combine with gas pipe passage (gas cock seat) with water pond; flow of inlet water with water pond is large and small; the input of control gas is many or few; make gas ignition add the temperature of hot water; as shown in Figure 1; water heater water pond A promotes valve plug C with penetrator ram B; gas is entered by the gas-entered passageway D of valve plug C below among the E of gas channel pipe for burning; then; there are many shortcomings in this kind water heater water pond A, thus the inflow of gas heater what all can not control the input of gas, usually have the abnormal several situations of water temperature and produce:

1, the diaphragm F chassis face among the water heater water pond A is smooth shape, when intaking by water intake G place,

The water yield can be along diaphragm F chassis face toward external diffusion, and the water yield can't be concentrated, and can't determine diaphragm past

Last passing.

2, up the strength of ejection is little for diaphragm F, makes the penetrator ram B pushing tow on the diaphragm uncertain, causes valve

Plug C rising displacement is not enough, and the gas input also reduces relatively.

3, valve plug C is arranged among the gas-entered passageway D, and when valve plug C up moved, gas could be logical by air inlet

Road D enters, yet valve plug C occupies most spatial position in gas-entered passageway D, therefore,

No matter valve plug C rising displacement is many or few (shown in Fig. 2,3), the air inlet of this gas-entered passageway D

Amount is still kept certain, can't increase or reduce, and also just can't regulate the temperature of water.

4, gas gas-entered passageway D is subjected to the influence of valve plug C, so that the input of gas all is certain, can't carry

Supply burning for more gas, thereby if the water yield is big, the not enough burning of gas can't be heated water promptly.

5, the chassis face of diaphragm F can't be concentrated the water yield, therefore, if inflow, promptly can't promote more after a little while

Diaphragm F, but just ejection diaphragm F of the more water yield must be used, quite expend water.

6, in hydropenic area, because of inflow little, ejection water heater water pond A, the power of diaphragm F

Inadequately, need than the time could be with the heating of heating for a long time, rate of heating is slow, uses inconvenience.

In view of this, the purpose of this utility model provides a kind of automatic temperature regulator of gas hot-water apparatus, it is to be subjected to water yield size with pressure-sensitive diaphragm, the height that control valve plug rises, and control coal gas input is also borrowed the raceway groove that catchments on the pressure membrane, and the water yield is concentrated, and coal gas is led the way on the confession valve plug, and a large amount of coal gas of introduction are arranged.

The purpose of this utility model is achieved in that a kind of automatic temperature regulator of gas hot-water apparatus, formed by water pond, pressure-sensitive diaphragm, gas inlet member and valve plug, wherein pressure-sensitive diaphragm is arranged in the water pond, it is characterized in that: the pressure-sensitive diaphragm below is provided with the raceway groove that catchments, and valve plug is provided with coal gas and leads the way; On the body of rod of described valve plug below coal gas being set leads the way; The thimble place of described pressure-sensitive diaphragm top is provided with spring.

Owing to adopting such scheme: can reach with water yield control coal gas input and regulate water temperature.
