Description
Technical field
The utility model is related to Heating, Ventilation and Air Conditioning (HVAC) Technology field, specifically a kind of H-type return water system intelligent temperature control valve.
Background technology
At present mainly hot water circuit confession is carried out in a manner that water flow switch adds circulating pump in the pipe network system of household water
Should, there are following two problems for aforesaid way：1st, the toilet from water heater distalmost end is generally required to wait for and be remained in hot-water line
Water at low temperature discharge after just have hot water；2nd, the berthing time that opens of the circulatory system is set, and the setting of time is manually to survey
Fixed, inevitably there are error, and such error frequently can lead to hot water and enter in cold water pipe, and user is caused to scald thing
The generation of part.
As shown in Figure 1, the schematic diagram for existing domestic hot water's circulatory system, form substantially and it acts as：(1) hot water
Device provides thermal water source；(2) temperature control loop control box, mainly by circulating pump and corresponding circuit board group into as hot water circuit system
The power source for cycle of uniting；(3) current conditions in pipeline are converted into switching regulator electric signal transmission and are recycled to temperature control by water flow switch
Control box, to reach opening/stopping for control loop system；(4) check valve, control flow, can not along the single direction flowing specified
Reverse flow；(5) hot water main pipe road, the conveyance conduit of hot water supply；(6) cold water main pipe road, the conveyance conduit of cold feed.
The basic principle of existing domestic hot water's circulatory system：
As shown in Figure 1, current domestic hot water's circulatory system will realize that the master of distalmost end defends and use hot water, it is to be beaten by user
It is closed after turning on the tap 2-6 seconds, water flow switch is made to sense the streamflow regime in pipeline, water flow switch again converts streamflow regime
Temperature control loop control box is transferred to for open signal, temperature control loop control box starts circulating pump, and passes through the work set in advance
Make the time is transported to the master of farthest by hot water and defends on time, and when reaching the setting working time, circulating pump is stopped.And temperature control
The working time of set circulating pump by measuring in advance manually in loop control box.Continuous mode needs first to open main defend
Tap, measure hot water from water heater to master defend the required time, the time of measure is then input to temperature control loop control box
In, to achieve the purpose that control loop pump operation time.Existing domestic hot water's circulatory system there are the problem of：Temperature control loop control
The minute inputted in box is labor measurement, inevitably will appear error, normally about 5-10 seconds very normal, Er Qiere
Water supervisor docks place with cold water main pipe without the effective management and control of temperature-sensing valve, then the error time of 5-10 seconds most likely results in two kinds of knots
Fruit：One kind is to setting time, and circulating pump stopped, but the master that hot water actually has not arrived farthest defends, and cause to lead
Hot water cannot be gone out in time by defending；Another situation is exactly that the operating of circulating pump time-out causes hot water being delivered directly in cold water pipe,
The so main moment water outlet defended will be all hot water, it is possible to scald user.
