Accompanying drawing explanation
Fig. 1 is principle schematic of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment
As shown in Figure 1, gas heater accurate temperature controlling energy conserving system, comprise by the heat-exchange tube that one end is connected with hot-water line, the other end is connected with cold water pipe, be connected with the burner for providing heat for heat-exchange tube of Gas Pipe, and be connected to the heat-exchange system of the burnt gas switch formation between Gas Pipe and burner; Control the PLC of heat-exchange system work; Be arranged at the temperature monitor be connected on hot-water line and with PLC; Be arranged at the gauge tap be connected on cold water pipe and with PLC.Wherein, burnt gas switch is connected with PLC, controls the duty of coupled burner according to the control instruction of PLC.
In the present invention, only can arrange the burnt gas switch of a burner and this burner operation state of control according to actual conditions people, PLC can reach by the opening degree of regulating gas switch the object controlling water temperature; In order to more accurately, expediently control water temperature, we select the burner arranging multiple power identical to control water temperature, wherein, each burner controls its duty with one and accepts the burnt gas switch that PLC controls to be connected respectively, in this case, PLC can carry out the working quantity of control combustion device by the unlatching quantity controlling burnt gas switch, thus reaches the object controlling water temperature.When real work, people can according to self custom burnt gas switch quantity that established standards temperature values and acquiescence open in PLC; When people open hot-water switch, hydraulic pressure microswitch then opens native system; When opening native system, the burnt gas switch that PLC controls to set quantity is automatically opened; Temperature monitor detects the temperature value in hot-water line in real time, and sends to PLC by detecting the temperature value drawn; PLC will detect the temperature value that draws and normal temperature value compares, and calculates and controls the unlatching quantity of burnt gas switch, the temperature value in hot-water line is maintained within the scope of the normal temperature value of setting.When people close hot-water switch, hydraulic pressure microswitch then cuts out automatically, and PLC then closes all burnt gas switch, system stalls.
