The purpose of this utility model provides a kind of big, energy-efficient volumetric gas water heater of pondage that can overcome above-mentioned shortcoming.
Volumetric gas water heater of the present utility model, comprise shell, water tank, flue, burner hearth etc., be provided with heat-insulation layer between shell and the water tank, the cross section of water tank is an annular, it is up and down the butterfly end socket, water tank upper is provided with the hot water outlet pipeline of over-temp and over-pressure relief valve and dribbling valve, in establish a magnesium system anode metal rod with reach prevent the corrosion, the purpose of clean water, the water tank bottom is provided with cooling water inlet, and by check-valves and ball valve and running water pipe connection, water tank bottom is provided with the blow-off pipe of dribbling valve, pass through the cross current of band hybrid regulator between cooling water inlet and the hot water outlet pipeline, there is the warm water outlet at the hybrid regulator place, and flue is located in the water tank, is straight barrel type, surround for water tank all around, windshield is arranged at the top, and heat sink is arranged in the flue, and heat sink is the water pipe formation that an outer surface is welded with the little first steel of some retaining cigarettes.The water pipe two ends are welded on the water tank, and are communicated with water in the water tank, and this device has increased heat transfer area, reached the purpose that improves the water heater thermal efficiency, burner hearth is surrounded by water tank bottom and furnace base, in be provided with gas combustion apparatus, gas combustion apparatus is by being contained in the combustion controller control on the body of heater.
Heat-insulation layer between shell and the water tank adopts the alumina silicate fibre material to make.
Burner in the burner hearth comprises that one has the cast iron burner of primary air shutter and the first flare of low-yield (0.3-0.4MJ/h).
It is positive near the gas combustion apparatus place that combustion controller is contained in the water heater bottom, one end of Gas controller is communicated with fuel gas source by gas pipeline, the other end is communicated with gas combustion apparatus by gas pipeline, during burning, combustion gas is come out from source of the gas, arrive gas combustion apparatus through combustion controller, in the burner hearth internal combustion.Gas controller is made up of piezoelectricity control point firearm and adjustability thermostat, and temperature automatically controlled function is arranged, and auto extinguishing when temperature reaches setting value when being lower than setting value, catching fire automatically, thereby the hot water temperature is controlled at setting range.
Volumetric gas water heater of the present utility model has simple in structurely, and the warm water and the hot water of cleaning can be provided at any time, is fit to the different instructions for use of people, and pondage is big, and temperature is easy to regulate, and can keep steady temperature, and radiation loss is little, thermal efficiency height.
Fig. 1 is the cutaway view of volumetric gas water heater of the present utility model, and Fig. 2 is a front view, and Fig. 3 is a volumetric gas water heater flue profile of the present utility model.1 is shell among the figure, the 2nd, and heat-insulation layer, the 3rd, water tank, the 4th, magnesium system anode metal rod, the 5th, flue, the 6th, retaining cigarette unit steel, the 7th, windshield, the 8th, burner hearth, the 9th, gas combustion apparatus, the 10th, base, the 11st, combustion controller, the 12nd, over-temp and over-pressure relief valve, the 13rd, blow-off pipe, the 14th, ball valve (outlet valve), the 15th, water pipe, the 16th, hybrid regulator, the 17th, ball valve (water intaking valve), 18 is check-valves.
