Abstract
The utility model relates to a gas water heater which can be used under the condition of low water pressure. The utility model is composed of a casing, a water inlet pipe, a water inlet valve, a preheating pipe, a heating pipe, a water outlet pipe, an air inlet pipe, an ignition switch, a gas valve, a manual switch of the gas valve and a burner, wherein, the diameter of the preheating water pipe is smaller than the diameter of an opening of the water inlet valve and is larger than the diameter of the heating water pipe; the diameter of the water outlet pipe is equal to the diameter of the heating water pipe. The utility model has the advantage of safe use and solves the problem that residents on high layers can not use a water heater because the water pressure is not enough.
Description
The utility model relates to a kind of for family provides the gas heater of hot water, particularly a kind of gas heater that can use under low hydraulic condition.
At present, gas heater uses very general.Existing gas heater is generally by shell, water inlet pipe, water intaking valve, the heating pipe, outlet pipe, air inlet pipe, ignition switch, gas valve, the gas valve hydraulic pressure switch, burner is formed, the skin drum of hydraulic pressure switch is contained in the water intaking valve, have only when water feeding pressure reaches certain value, just can make skin drum bump air valve thimble, open gas valve, this just brings two problems, and the one, the low air valve of not opening of the high-rise Chang Yin of resident family hydraulic pressure, and can't use water heater, both made certain hydraulic pressure open air valve, also exist the hydraulic pressure deficiency, combustion flame is little, and water yield is little, problems such as water temperature is high inadequately, the 2nd, long or assemble reasons such as improper owing to service time, easily cause the air valve thimble of hydraulic pressure switch malfunctioning, stop into water after, air valve closes not tight, burner burns away, even water heater is burnt out, and uses dangerous.The present solution of the problems referred to above is to purchase booster water pump and often maintenance, the economy spending that this will increase electricity consumption and increase people.In addition, the heating pipe of existing water heater is straight pipe, it is relatively large to take up space, and heating surface area is less relatively, the heat energy of combustion gas fails to make full use of, and leaving water temperature is not high enough on the one hand, and heat-energy losses is to shell on the other hand, often shell upper is hot during water heater working, even burnt.
The purpose of this utility model is, the structure of existing gas heater is improved, and a kind of gas heater that can use under low hydraulic condition is provided.
The further purpose of the utility model is that a kind of low hydraulic pressure gas heater that makes full use of combustion gas heat energy is provided.
The composition of the low hydraulic pressure gas heater of the utility model comprises shell, water inlet pipe, water intaking valve, heating pipe, outlet pipe, air inlet pipe, ignition switch, gas valve and switch thereof, burner, it is characterized in that: 1, gas valve has the hand switch of being made up of rotating shaft and knob, 2, the heating pipe is divided into economizer bank and heating tube, economizer bank connects water intaking valve, heating tube connects outlet pipe, the economizer bank diameter is less than water inlet valve port diameter and greater than the heating tube diameter, diameter of outflow tube and heating tube equal diameters.The further feature of the utility model is, heating tube coils shape in the shape of a spiral above burner, and economizer bank is horizontal straight tube, is positioned at the heating tube top.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is that the utility model gas valve and hand switch A thereof are to schematic diagram.
As shown in Figure 1, the low hydraulic pressure gas heater of the utility model is made up of shell 1, water inlet pipe 9, water intaking valve 8, heating pipe 2,3, outlet pipe 7, air inlet pipe 10, ignition switch 11, gas valve 5, burner 4, gas valve 5 has the hand switch of being made up of rotating shaft (among Fig. 2 shown in 13) and knob 6, the heating pipe comprises economizer bank 2 and heating tube 3, economizer bank 2 connects water intaking valve 8, heating tube 3 connects outlet pipe 7, economizer bank 2 diameters are less than the water inlet valve port diameter, and greater than heating tube 3 diameters, outlet pipe 7 diameters and heating tube equal diameters.Among the embodiment, the water inlet valve port diameter is 20 to 22 millimeters, and the economizer bank diameter is 12 to 14 millimeters, and the heating tube diameter is 10 to 12 millimeters.The utility model replaces hydraulic pressure switch with manual gas valve switch, whether open and what of air inflow of gas valve are not subjected to the control of water feeding pressure, hydraulic pressure also can use water heater when low, and can artificially regulate air inflow as required, and main be, artificial control air valve switch improves greatly than water pressure-controlled air valve switch safety coefficient.Simultaneously, owing to do not contain hydraulic pressure switch in the water intaking valve, it is big that the space becomes, increased inflow, water inlet is through three kinds of descending calibers, and hydraulic pressure also constantly raises in heated process, obtains hot water that hydraulic pressure raises to some extent than water inlet, that water temperature meets demand by outlet pipe at last.Heating tube 3 coils shape in the shape of a spiral among the embodiment above burner 4, economizer bank 2 is horizontal straight tube, be positioned at heating tube 3 tops, in former the having living space of water heater, increased the hot-water line heating surface area, sufficiently and reasonably utilize the heat energy of burner, the water heater thermal efficiency is improved, and the water outlet water temperature than improving about 10～15 ℃ usually hot the or burnt phenomenon of shell can not take place.
As shown in Figure 2, the gas valve hand switch that gas valve 5 is housed and forms on the air inlet pipe 10 of the present utility model by rotating shaft 13, knob 6.1 is outer cover of water heater among the figure, and 17 for hanging the wall of water heater, and 14 is the gas valve spool.People in the bathing of wall next door controls the gas valve switch for convenience, regulates water temperature at any time, and the further feature of the utility model is that the hand switch of being made up of rotating shaft 13 and knob 6, rotating shaft 16 and knob 15 is equipped with at gas valve spool 14 two ends respectively.
Claims (3)
1, a kind of gas heater that can under low hydraulic condition, use, its composition comprises shell, water inlet pipe, water intaking valve, heating pipe, outlet pipe, air inlet pipe, ignition switch, gas valve and switch thereof, burner, it is characterized in that:
(1), gas valve has the hand switch of being made up of rotating shaft and knob,
(2), the heating pipe is divided into economizer bank and heating tube, economizer bank connects water intaking valve, heating tube connects outlet pipe, the economizer bank diameter is less than the water inlet valve port diameter and greater than the heating tube diameter, diameter of outflow tube and heating tube equal diameters.
