Abstract
The utility model provides a temperature control cycle device for a pipeline of a solar water heater, and the device comprises a water tank, a temperature control cycle pipeline which is connected under the water tank, and a hot water pipeline. One end of the hot water pipeline is communicated with a temperature difference cycle pipeline which is provided with a sensor, a temperature difference cycle valve and a check valve. The sensor and the temperature difference cycle pipeline are communicated with a control center. The temperature difference cycle pipeline can be connected with a warm air return pipe at the upper end of the check valve, and the warm air return pipe is connected with the check valve. The device adopts the temperature control cycle pipeline to carry on timing cycle to water in the hot water pipeline, and can keep the temperature of hot water for a long time, that is, cold water has no need to be exhausted for a long time, so that the water resource is saved, and simultaneously, the time that users wait for the hot water is reduced. Because the water in a water pipe keeps at certain temperature, the phenomenon that the water is frozen in the water pipe can not occur in cold winter, either.
Description
Technical field
The utility model relates to a kind of solar water heater, particularly a kind of pipeline temperature control EGR that can guarantee the solar water heater of user side water temperature stability.
Background technology
At present, the most of pipe-lines of Solar Heater Market are longer, and the user need sacrifice the long period and waste ducted cold water and just can use desirable hot water, and freezing clogging can occur when temperature is low, thereby influence user's normal use.
The utility model content
The utility model provides the pipeline temperature control EGR of a kind of solar water heater that can guarantee the user side water temperature stability.
In order to solve above technical problem, the pipeline temperature control EGR of a kind of solar water heater of the present utility model, comprise temperature control circulating line, hot water pipeline that water tank, water tank connect down, one end of described hot water pipeline is communicated with the temperature control circulating line, sensor and temperature control circulating valve are housed on described temperature control circulating line, and described sensor is communicated with control centre.
Upper end at check-valves on the described temperature difference circulating line can connect the heating installation return duct.
Be connected to check-valves on the described heating installation return duct.
The pipeline temperature control EGR of a kind of solar water heater of above structure is owing to adopt the temperature control circulating valve that the water in the hot water pipeline is regularly circulated, control to water temperature has following advantage: 1, avoid user side to cause the water in the water pipe to turn cold for a long time without hot water, keep the stability of user side water temperature; 2, the user side with hot water need not only economize on resources for emitting cold water for a long time with hot water, also reduces the hot water times such as user; 3, in the winter of cold, because of the water in the water pipe keeps certain temperature, the phenomenon that water pipe freezes can not take place.

Fig. 2 is the structural representation of the utility model band heating installation return pipe;
Fig. 3 is the structural representation that two water tanks of the utility model connect.
The specific embodiment
Concrete enforcement 1:
As shown in Figure 1, water tank 1 is non-press-bearing water tank, connects temperature difference circulating line 2 and hot water pipeline 3 below water tank 1 respectively, is communicated with between circulating line 2 and the hot water pipeline 3, and forms water circulation system between water tank 1 three; Connect check-valves 11, temperature difference circulating valve 4 and sensor 7 on the described temperature control circulation pipe 2, wherein sensor 7, temperature difference circulating valve 4 all are connected with control centre, and temperature that control centre is responded to according to sensor 7 and design temperature are to recently controlling the open and close of temperature difference circulating valve 4; Can be divided into some tributaries on the described hot water pipeline 3 and enter user side; During work, configure the temperature of sensor 7, when the temperature of sensor 7 is on the low side, the temperature difference circulating valve 4 on the temperature difference circulating line 2, under the effect of control centre, open, water to 1 li in the water in the hot-water line 3 and water tank carries out a circulation, again since the anti-sealing of check-valves 11 single effects reflux; Like this, water in the water pipe is uninterruptedly circulation within a certain period of time, water in the non-press-bearing water tank 1 can not be back in the temperature control circulation pipe 2 again, even therefore user side water not for a long time, the shower nozzle of fetching boiling water, ejection be still hot water, hot water can not occur and be trapped in the water pipe for a long time and turn cold, freeze, guaranteed the stability of user side water temperature; In addition, if in the lower north of winter temperature, can also connect on the temperature control circulating line 2 temperature control circulating valve 4 above be communicated with a heating installation return pipe 6 again, as shown in Figure 2.Form a water circulation system between heating installation return pipe 6 and temperature control circulating line 2, the water tank 1 again; Equally, on heating installation return pipe 6, still be connected to check-valves 11 minutes, and divide some tributaries to enter user side, and heating installation return pipe 6 is identical with hot water pipeline 3 with the effect of temperature control circulating line 2 circulations, and the effect of check-valves 11 is also identical with check-valves 11 effects on the temperature control circulating line 2.
Specific embodiment 2:
As shown in Figure 3, water tank is two, one is the non-press-bearing water tank 9 that directly links to each other with heat collector 8, one is the press-bearing water tank 10 that directly is connected with user side, temperature control circulating line 2 links to each other with non-press-bearing water tank 9, one end of hot water pipeline 3 links to each other with press-bearing water tank 10, the other end communicates with temperature control circulating line 2, if still keep heating installation, heating installation return pipe 6 still with temperature control circulating line 2 on the check-valves 11 established, the top of temperature difference circulating valve 4 is communicated with, like this, when sensor 7 displays temperatures are on the low side, temperature difference circulating valve 4 on the temperature difference circulating line 2 is opened under the effect of control centre, hot-water line 3, the cold water of warm water return pipe 6 just flows into non-press-bearing water tank along temperature difference circulating line 2, and the single effect of check-valves 11 has prevented that the water of 1 li of non-press-bearing water tank from entering, and the hot water of press-bearing water tank 1 is full of hot-water line and warm water return pipe 6 downwards, the temperature stabilization that has guaranteed user's water like this, equally is reliable.
