For guaranteeing the minimum water temperature in hot-water heating system least favorable supply centre, the existing technical scheme that adopts is for being provided with hot water cyclesystem, as shown in Figure 1: cold water pipe 1 is connected with external water source, cold water pipe 1 is also connected to the water inlet of water heater 7, and be connected to each watering equipment as pond 15, toilet 14 and shower 13, for watering equipment provides cold water; Cold water flows to water heater 7 heating, and heated hot water enters hot-water line 2, needs the sanitary apparatus hot-water supply of hot-water supply to pond 15 and shower 13 etc.; Connecting portion at cold water pipe 1 and external water source has control valve 3, at the water inlet of water heater 7 control valve 4 is arranged, and at the delivery port of water heater 7 control valve 5 is arranged; Water inlet at water heater 7 has check-valves 8 to be used to prevent aqueous reflux; Set up one section aqueduct and be connected to the water heater water inlet by the distal-most end hot-water line, on this aqueduct of setting up, be connected with control valve 6 in turn, water temperature sniffer 10, hot water circulating pump 11, check-valves 16, control valve 17, when for a long time without hot water, water temperature descends in the hot-water line, water temperature sniffer 10 water temperature detections are lower than to be set when requiring, automatically open hot water circulating pump 11, the hot water circuit backheat hydrophone 7 that turns cold in the hot-water line 2 is heated automatically, water after the heating turns back to hot-water line 2, form the circulation heating of hot water, when water temperature sniffer 10 water temperature detections reach set water temperature, hot water circulating pump 11 stops automatically.Though this kind method can satisfy instructions for use, but need special hot water circuit pipeline is installed, can the finishing of having finished be damaged.
The utility model content
The purpose of this utility model provides the constant relatively hot water circuit return pipe of water temperature in a kind of permanent maintenance hot water pipeline, does not change the hot and cold water pipeline under the existing finishing substantially.
Hot water circuit return pipe of the present utility model is achieved by following technical proposals:
The hot water circuit return pipe, comprise the cold water pipe 1 that is connected with external water source, cold water pipe connects control valve 3 successively from entering this water system, be used to prevent that intrasystem aqueous reflux from going out the check-valves 8 of system, cold water pipe 1 is connected respectively to the water inlet and the watering equipment 9 of water heater 7 from the water outlet side of check-valves 8, the delivery port of water heater 7 connects hot-water line 2, hot-water line is connected to watering equipment 9, water inlet at water heater 7 is connected with control valve 4, delivery port at water heater 7 is connected with control valve 5, between the cold and hot water inlets of watering equipment 9, be connected with recirculation assembly, this recirculation assembly is 1 control valve 6 that connects successively from hot-water line 2 to cold water pipe, water temperature sniffer 10, hot water circulating pump 11, magnetic valve 12, magnetic valve 12 be used for hot-water heating system not circulation time cut off water in hot-water line 2 and the cold water pipe 1, when preventing that watering equipment 9 from only using cold water faucet, hot water flows out, and wastes energy.Wherein, control valve 3,4,5,6 can be the valve that stop valve, gate valve or ball valve etc. can be closed current, and water heater 7 is controlled the open-type water heater automatically for current.
When for a long time without hot water, cause water temperature reduction in the hot-water line 2, near this moment watering equipment 9 on the hot water pipelines water temperature sniffer 10 detects water temperature and is lower than the setting requirement, hot water circulating pump 11 and magnetic valve 12 start automatically, water in the hot-water line 2 is forced to pump into cold water pipe 1, current are controlled automatically and are opened water heater 7, the water that pumps in the cold water pipe 1 outputs to hot-water line 2 after water heater 7 heating, in case water temperature sniffer 10 detects the water temperature that water temperature reaches setting, then stop hot water circulating pump 11 and magnetic valve 12 automatically, finish the circulation heating of hot water, guarantee the water supply water temperature of hot-water heating system.During normal the use, control valve 3,4,5,6 all is in opening, and when needs overhaul or stop using, in order to cut off the water supply.
Hot water circuit return pipe of the present utility model compared with prior art has following good effect:
Can keep the interior water temperature of hot water pipeline constant relatively for a long time, overcoming when using hot water often needs to bleed off earlier the drawback of part cold water, and does not change the hot and cold water pipeline under the existing finishing substantially.
