Description
Technical field
The utility model relates to the water supply of feed water heater field more particularly to a kind of flexible transfiguration water tank of band heating
Device.
Background technique
In existing feed water heater, the stability of water temperature is the key technology of feed water heater, flowed fluctuation
It is the main reason for causing water temperature fluctuation, as long as solving the flowed fluctuation in feed water heater use process in system
Solve the fluctuation of water temperature.
Currently, the water temperature control in industry in feed water heater is mainly divided to two class schemes:
First kind scheme, flowed fluctuation pre-control in water route adjusts water temperature, before water flow changes, by adjusting heater
Power, to realize the fluctuation for reducing water temperature, the realization of this scheme needs first to understand water circuit system flow in all cases
Changing value realizes that this scheme control water temperature fluctuation is more difficult to software algorithm and control system predesigned compensation, and fluctuating range compared with
Greatly, consistency is bad, and this scheme is unable to control and leads due to mains ripple causes heater power to fluctuate in system
The water temperature fluctuation of cause.
Second class scheme, heater rear end in feed water heater increase the mixed water tank of fixed capacity, in water tank
Water play the role of neutralize water temperature, water tank is bigger, and system water temperature stability is relatively better, to flow system flow and heating power
Fluctuation causes water temperature fluctuation, plays the role of neutralizing water temperature, but this scheme will increase the pipe volume of water system, increase cold water
Amount increases system and arranges the cold water time, so mixed water tank cannot be done greatly, so can only have certain modulability to water temperature.
Therefore, current above scheme can not guarantee water temperature of the feed water heater when carrying out water route switching well
Stability.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of flexible transfiguration water tanks of band
Feed water heater, can solve cannot guarantee that feed water heater is carrying out water route switching well in current above scheme
When water temperature stability the problem of.
The utility model provides purpose and is implemented with the following technical solutions:
A kind of feed water heater of the flexible transfiguration water tank of band, including water inlet vacuum solenoid valve, several aqueducts, water add

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
It is poor for the water temperature stability of water heating system, in the prior art, solved the above problems using following two scheme,
First kind scheme, flowed fluctuation pre-control in water route adjusts water temperature, before water flow changes, by adjusting the power of heater,
To realize that the fluctuation for reducing water temperature, this scheme realization need first to understand water circuit system flow volume change values in all cases,
Software algorithm and control system predesigned compensation are realized, this scheme control water temperature fluctuation is more difficult, and fluctuating range is larger, unanimously
Property it is bad, and this scheme be unable to control because in system mains ripple cause heater power fluctuate caused by water temperature
Fluctuation.
Second class scheme, heater rear end in feed water heater increase the mixed water tank of fixed capacity, in water tank
Water play the role of neutralize water temperature, water tank is bigger, and system water temperature stability is relatively better, to flow system flow and heating power
Fluctuation causes water temperature fluctuation, plays the role of neutralizing water temperature, but a little schemes will increase the pipe volume of water system, increase cold water
Amount increases system and arranges the cold water time, so mixed water tank cannot be done greatly, so can only have certain modulability to water temperature.
In the function of Association Standard " CBMF 15-2016 " washer, it is desirable that washer stretches out in place in 8s,
As shown in figure 3, the temperature waveform diagram when standard of the washer in professional standard works, washer is discharged 1 second after stretching out
It is interior to reach 35 DEG C, up to 40 ± 2 DEG C in 3s, the temperature that initial temperature is water temperature when be heating, when end point is 1 second after stretching,
The temperature reached i.e. 35 DEG C.It is illustrated in figure 4 the temperature waveform diagram of washer in the prior art in actual work, it is above-mentioned
First kind scheme reaches 40 ± 2 DEG C after meeting washer 8s and stretching out the requirement for being discharged reach 35 DEG C or more in 1s in place in 3s
When, it is subsequent t as shown in Figure 4 occurh、tlFluctuation, thFor the maximum temperature value reached in temperature wavy curve, tlFor temperature
Lowest temperature angle value after reaching maximum temperature value in wavy curve.th、tlFluctuating range is larger, i.e., difference is larger, i.e., temperature is unstable
It is fixed, keep difficulty of its difference control in ± 2 DEG C larger.T in the second class scheme, in Fig. 3h、tlFluctuating range can be controlled effectively
System, water tank capacity get over that great fluctuation process amplitude is smaller, but the volume of water tank can only do very little, and cleaning is required in " CBMF 15-2016 "
It is stretched out in place in device 8s, water temperature reaches under 35 DEG C of requirements above in 1s, this needs the cold water in water system pipeline must be in 8s
It is drained, and 35 DEG C are added in 1s, first kind scheme meets standard requirements close to critical state in the time, so the second class scheme
Increased on the basis of first kind scheme to hold water tank admittedly, when optimizing water temperature fluctuation, washer stretches out water in 1s in place
Temperature reach 35 DEG C or more be it is relatively difficult, very little can be designed by holding water tank capacity in practice admittedly, can only make th、tlFluctuation symbol
Standardization requirement.(such as: feed water heater maximum stream flow 660ml per minute, i.e., 11ml per second, the common heater in market will
To 35 DEG C of 4~5s of basic need, washer stretches out in place and is heated to 35 DEG C or more to be completed in 9s water temperature heating, so
The drained pipeline cold water of system must be completed in 5s, if holding water tank 11ml admittedly, feed water heater row's cold water just needs to increase
The 1s time can only improve fluctuation so holding water tank capacity very little admittedly).
