Abstract
The utility model relates to a separated flow-stabilizing gas water heater, comprising a combustion apparatus and a regulation device. The utility model is characterized in that the combustion device is provided with a seasonal combustion control key; the adjustment of the volume of water in the regulation device is realized by adjusting the venturi pipe and the pressure difference signal of the both sides of the water and valve film through a needle-shaped valve; the switching valve of the water path is a late release type, solving the problem that the stopping of the water causes the rising of the temperature.
Description
The utility model relates to a kind of gas heater.
Gas heater on city's field boundary all is burning and control one at present, and this environment for use and mounting condition to it all has the certain limitation requirement, and the user controls water temperature, the water yield also inconvenience.More satisfactory a kind of design is that the burning heating part of gas heater is separated with the control and regulation part, make split type gas heater, this respect has many inventive concepts, but major part still belongs to isolation simply, what have is having specific (special) requirements on the technical conditions or on the mounting condition, what have exists potential safety hazard, and what have is not suitable for environment for use, thereby does not have a promotional value.In addition, existing gas heater suspends the short time operation, and the part heat that heat exchanger stores can make the water temperature that stops in it continue to rise, and this temperature rise of cutting off the water is given to use to regulate and made troubles, also easy damage device with cause the scald accident.Moreover existing gas heater water film valve is voltage regulation type, and it can keep stable water pressure but not necessarily guarantee stability of flow, and the flow shakiness then means the water temperature shakiness.
The utility model aims to provide a kind of burner and regulation device split, the water yield are stablized, be easy to adjust joint keeps cutting off the water the little gas heater of temperature rise,
Below in conjunction with description of drawings structure of the present utility model and principle.
Figure one is the utility model structural representation.
Figure two is the utility model regulation device schematic diagram.
Referring to Fig. 1, the utility model is equipped with burning operating key 2 at burner 1, is used for regulating in Various Seasonal quantity and or the gaseous-pressure of burner operation. The break-make of combustion gas gas circuit and the combustion of flame are gone out and are by being located at magnetic valve 3 controls on the gas circuit, and the action of magnetic valve 3 is under the orders of and has detected electric control gear 4 and the igniter 8 that sends instruction behind current and the flare up fire, waterway control system is separated from water heater, form independently regulation device 5, it is installed in the bathroom, be connected with burner 1 by water pipe 6, lead 7, switch 9 department pipe two parts water routes above it and the break-make of circuit, that is the work of whole water heater with stop. If necessary, also available fiber is conducted the flame combustion sight to observation window 19.
Referring to Fig. 2, regulation device 5 mainly is made up of the switch valve 14 of switch 9, steady flow control valve 11, time-delay closing. Steady flow control valve 11 is made up of moisture film control valve 19, needle valve 12 and Venturi tube 13. Generally do not establish in the situation of needle valve 12, when current are flowed through Venturi tube 13, form the pressure reduction that is directly proportional with flow in water film valve film 20 both sides, active force and spring 21 power that this pressure reduction produces balance each other, and moisture film is regulated The spool of valve 19 is stabilized on some positions, thereby makes flow of water constant. Can come regulating pondage with the method for direct regulating spring 21 power, but implement inconvenience. The utility model arranges needle valve 12 at the passage of UNICOM water film valve film 20 both sides, regulates the aperture of needle valve 12, just can change the pressure difference signal that Venturi tube 13 is exported, thereby obtains the water yield of different sizes. Utilize this mode regulating pondage, easy operating, safe and reliable. Should be the unlikely permission least quantity that is burned of water heater during needle valve 12 full cut-off.
At the flow inlet place of regulation device 5 is switch valve 14, the utility model is designed to instantaneous unlatching with switch valve 14, the form of time-delay closing, it is characterized in that on the valve lever 22 of switch valve 14, being with leather cup concentric 15 and sleeve 16 with it, leather cup 15 center are fixing on valve lever 22, the traffic direction of the rim of a bowl when valve lever 22 is closed, the shirt rim is close on sleeve 16 inwalls, keep necessarily airtight, sleeve 16 be installed on the switch valve 14 or regulation device 5 on other fixable positions, end at the bottom of 15 bowls of its corresponding leather cups has airway smoothly, an end of its corresponding the rim of a bowl, position beyond the leather cup 15 movable strokes has throttle orifice 17.When opening switch 9, lever 18 drives the direction motion at the bottom of the bowl of valve levers 22 and leather cup 15, and leather cup 15 shirt rims are contraction-like, and sleeve 16 these ends have airway in addition, and therefore not having vapour lock influences valve lever 22 breakdown actions.When closing switch 9, leather cup 15 expands towards the rim of a bowl direction motion shirt rim, and the air in the sleeve 16 is compressed and can only slowly releases from throttle orifice 17, so valve lever can only microinching, the slowly spool of valve-off 14.Close complete shut-downs to valve 14 and live from closing switch 9 fray-outs of flame, continue flowing water flow in during this period of time can take away remaining heat in the heat exchanger.Switch 9 is run the pass jointly for water, Electricity Federation, in fact also be internal heat switch, connect simultaneously when opening, burner operation, circuit cuts off immediately when closing, burner quits work, current postpone a period of time just to be stopped.
