Abstract

The utility model relates to a coiled pipe water-heating boiler which belongs to the technical field of the normal-pressure water-heating boiler and solves the problems that the common normal-pressure water-heating boiler can not supply hot water for showering because the rated steam pressure is too low to heat the water tank in high water level. The utility model is characterized in that a pair of coil pipes is arranged in the normal-pressure water-heating boiler, so the utility model satisfies the urgent requirement of showering in the public bathhouse in the countryside, the middle city and the small town.

Description

The coiled hot-water boiler

The utility model belongs to the normal-pressure hot-water boiler technical field.

Known to the applicant, present normal-pressure hot-water boiler, the nominal steam pressure of national regulation is all lower, is not enough to heat the boiler of high water level.Therefore, in needing the bathhouse of shower, can only use heat-exchanger pump to the elevated tank delivering hot water by the hot water Turnover Box, to obtain the required drop of shower.Like this, just increased a large number of expense of the facility such as hot water Turnover Box, heat-exchanger pump, elevated tank in bathroom, but also taken valuable construction area.

The purpose of this utility model is utilized the pressure of running water itself exactly, without the hot water Turnover Box, and hot water force (forcing) pump and elevated tank, the drop problem of required water when in the same old way solving shower.

The utility model is design like this: in common normal-pressure hot-water boiler, around the inner bag of boiler, a bracket panel pipe is installed, boiler is stretched out at the two ends of coil pipe, and an end directly is connected on the running water pipe, and another termination is on shower bath.

When boiler was heated to uniform temperature with its internal water, the hot water of boiler own was normally done also the running water by coil pipe to be heated to uniform temperature outside other use, is enough to use for shower.By test, when hot-water boiler is boiled water, promptly reach 100 ℃, cold running water is by behind the coil pipe, and its temperature is enough to use for shower about 90 ℃.

The contrast accompanying drawing is further described below.

Fig. 1 is the structure operation principle schematic diagram of coiled hot-water boiler.

Among the figure: 1. combustion chamber 2. inner bag fire tubes 3. exhaust fume collecting hoods 4. body outlet pipes 5. furnace shells 6. coil pipe water inlet pipes 7. body water inlet pipes 8. chimneys 9. water inlet transferring box 10. coil pipe outlet pipes 11. coil pipes 12. manholes

As can be seen from Figure 1, main body of the present utility model is a normal-pressure hot-water boiler, all required annexes of boiler are housed on furnace shell 5, (this figure does not draw) is during heating, in combustion chamber 1, fuel combustion, flue gas has heat and rises, and through inner bag fire tube 2, exhaust fume collecting hood 3 and chimney 8, discharges.The route of its water is, cold water enters boiler internal by body water inlet pipe 7, overflows into furnace shell inside by water inlet transferring box 9, is heated intensification, and hot water or opening provide use by body delivery port 4.In the outside of inner bag fire tube 2, a bracket panel pipe 11 is around its week, and an end of coil pipe 11 is coil pipe water inlet pipes 6, directly is connected on the running water pipe, and the other end is a coil pipe outlet pipe 10, and it is directly linked on the bath tube.Cold running water is entered in the coil pipe 11 by coil pipe water inlet pipe 6, and by hot water heating on every side, rotation in coil pipe 11 heats up gradually, externally exports from coil pipe outlet pipe 10.Its temperature can reach 70-90 ℃, and because running water itself has certain pressure, is enough to produce required drop of shower and lower punch power amount.

The utility model has the advantages that: the boiler floor space is little, and is energy-conservation, applicable to public The shower in bathroom, be specially adapted to the vast rural area of China and in, samll cities and towns are current Active demand.

Claims

1, a kind of coiled hot-water boiler is characterized in: in common normal-pressure hot-water boiler, around the inner bag of boiler, a bracket panel pipe is installed, the boiler outside is stretched out at the two ends of coil pipe, and an end is directly received on the running water pipe, and the other end is connected on the shower bath.
