Description
Technical field
The present invention relates to field of water heaters, and in particular to a kind of gas heater of the bypass pipe with water transfer proportioning valve.
Background technique
Gas heater in use, after closing depotition cock is cut off the water suddenly, goes out when being again turned on gas heater
Water temperature may increase suddenly after tap, and will appear a Duan Lengshui, and hot and cold water is alternately present, and seriously affect shower
Comfort.This is because the high temperature fin on heat exchanger still has preheating, it can be passed after closing water outlet of water heater faucet is cut off the water
It passs and rests on the relatively low water of temperature in water heater pipeline, increase the temperature of the water in pipeline, when being again turned on faucet
When using hot water, people can not take a shower for this part high-temperature-hot-water rested on inside water heater, and when just having started water heater, due to
Water heater, which is lighted and heated, to be made hot water reach set temperature to need certain time, after the high-temperature-hot-water in water heater discharges at this time,
It has one section of cold water again to occur, hot water just reaches the bathing requirement that set temperature meets people after a period of time.This pass water
The phenomenon that hot water temperature caused by starting water heater increases suddenly again afterwards halts water temperature liter, and water cut-off temperature-rising problem is to allow consumer
One of the problem of headache, this problem have caused the attention of many water heater manufacturers.
Gas heater in use, encounters extraneous hydraulic pressure fluctuating change, and water yield can and then change, and hydraulic pressure becomes
Height, water yield will increase, then hot water temperature can reduce out；Hydraulic pressure is lower, and water yield can be reduced, then hot water temperature can increase out.
As constant temp gas water heater, has the function of that water high fire is big, water small fire is small, can finally guarantee hot water temperature out and set temperature
It is consistent, when water flow becomes larger, combustion gas also and then becomes larger, but since the heating process of water heater has certain lag
Property, a part of water of foremost has little time to be heated, so will appear the phenomenon that hot water temperature is lower than set temperature in short-term out；Instead
It, when water flow becomes smaller, the waste heat that combustion gas also and then becomes smaller, and retains on heat-exchanger fin can make a part of foremost
Water continues to be heated, so will appear the phenomenon that hot water temperature is higher than set temperature in short-term out；The water occurred during bathing
The sometimes hot and sometimes cold phenomenon of temperature can all bring not well experience to user.
Gas heater after a period of use, often there is verdigris appearance on heat exchanger surrounding inner wall and fin, this is
Because water heater is when low load condition is run, flue-gas temperature is not high, and nearby local flue-gas temperature is lower than dew point to fin, is formed cold
Condensate.There is sour gas to be dissolved in wherein in condensed water, in acidity, when a part of water of these condensed water re-evaporations, solution acidic becomes
By force, also become strong to the corrosivity of heat exchanger, in addition also have unburnt carbon granules and also be soluble in condensed water formation thick liquid
It is adsorbed on fin, long-term accumulation, many thick liquids is adsorbed on fin, block flue gas emission channel, cause to discharge fume unsmooth, cause
More imperfect combustion phenomenons, substantially reduce the heat exchange efficiency of heat exchanger, while reducing the service life of heat exchanger.
The prior art increases bypass pipe on water heater, and water cut-off temperature-rising can be reduced and one by increasing bypass pipe
Determine the generation that condensed water is reduced in degree.When bypass conduit-free, in the identical situation of setting leaving water temperature, hot water exit's
Temperature is equal to the water temperature of heat exchanger；When there is bypass pipe, the temperature of hot water exit be equal to the water temperature of heat exchanger with
The mixed water temperature of the water temperature of bypass pipe is flowed through, in order to which reach setting goes out hot water temperature, in heat exchanger when having bypass pipe
Water temperature must be higher than hot water exit's temperature, so increasing the production that bypass pipe advantageously reduces internal heat exchanger condensed water
It is raw；Simultaneously water heater close suddenly tap deactivate after, have bypass pipe than there is no the internal heat exchanger water temperature of bypass pipe
The temperature difference between height, with fin is reduced by, and the heat for passing to the water rested in pipeline after cutting off the water by fin just reduces
, when being again turned on water heater, then corresponding water cut-off temperature-rising also just reduces.
Although the above advantageous effect can be generated when increasing bypass pipe on gas heater, but if by-pass ratio (bypass pipe
Internal diameter/heat exchanger is responsible for internal diameter) if selection is excessive, negative interaction can be also generated to gas heater, by-pass ratio selection is excessive
It can make internal heat exchanger water temperature over-high, it will cause following negative interactions for the water temperature over-high in heat exchanger: 1), in heat exchanger
The increase of water temperature can be such that exhaust gas temperature increases, and the thermal efficiency of gas heater is caused to decline.2), in heat exchanger water temperature it is excessively high
The noise that boiling may be generated reaches fluidizing point since heating is unevenly likely to result in local water temperature, generates boiling noise.
3), water temperature over-high can be such that heat exchanger is increased by the number of cooling thermal impact in heat exchanger, will affect the use of heat exchanger
Service life.
Xian Yeyou producer is the water cut-off temperature-rising for reducing gas heater, mitigates gas heater in use because of hydraulic pressure
Go out the sometimes hot and sometimes cold phenomenon non-comfort caused by people of hot water temperature caused by fluctuating change, increases at water heater hot-water outlet
A water tank is added.In use, the water temperature in water tank is gas heater with hot water temperature out and setting temperature
It is consistent, it closes out after hot water tap cuts off the water, the waste heat on heat-exchanger fin can continue to heat to the water rested in its pipe,
Tap is opened again suddenly using hot water, the water temperature flowed out out of heat exchanger tube can be very high, can be with storage when flowing through water tank
The water mixing of normal temperature, temperature of the water temperature lower than the water come out directly out of heat exchanger tube after mixing in water pot.So storage
Water pot can reduce the water cut-off temperature-rising of gas heater, and reduction degree is related to water tank volume size, and water storage tank volume is bigger, subtracts
The effect of small water cut-off temperature-rising is better.In addition gas heater encounters water temperature caused by due to water pressure fluctuations variation in use
The phenomenon that sometimes hot and sometimes cold variation, either high-temperature water in short-term or water at low temperature, when flowing through water tank, through mixed with the water in tank
After conjunction, the amplitude of water temperature fluctuation variation can be all weakened severely, and reduce the bad Experience Degree of hot water user.
Although can generate the above advantageous effect when gas heater water outlet increases water tank, it is unfavorable also to generate
Influence, 1), gas heater is when being used continuously, the water temperature in water tank is consistent with cold water temperature, when starting gas heater,
Water in water tank cannot be heated, thus it is longer the time required to hot water can be gone out than the gas heater of not water tank, it is time-consuming
Water wasting, user's winter are especially experienced not well；2), since water tank needs to play the role of mixed water, water inlet position is low, water outlet
Position is high, has part water not flow always in tank, may breed after long-time thin；3), water storage tank volume is big, relatively takes up space,
It is required that need to bear 1.5MPa pressure as the other pipelines of gas heater, it is more demanding to the manufacture craft of water tank.
