The utility model content

Technical problem of the present utility model is the interchangeable heat water-circulating pump device that a kind of conserve water resource will be provided.

In order to solve above technical problem, it is device that the utility model provides a kind of interchangeable heat water-circulating pump, the last delivery port of water heater hot-water outlet pipe is communicated with the cold water inlet of water heater by ready-made cold water pipe, promptly use ready-made cold water pipes as the circulation return pipe, constitute a closed-loop path, a booster pump of serial connection and a normally closed solenoid valve in this loop, booster pump and magnetic valve are subjected to a control box gauge tap, control box connects a temperature probe, and temperature probe is measured the last water side water temperature of hot-water line.

Described booster pump is directly controlled or remote control by control box.

Operation principle of the present utility model:

1, when all hot water taps are when same hot water pipeline branches away, as long as in the end hot water tap locates to install a magnetic valve that connects cold water pipes, and this magnetic valve and the controlled box of the booster pump of useing circulating pump as are controlled, action simultaneously, circulating pump starts circulating water flow, circulating water flow makes the gas heater igniting, to the hot water pipeline delivering hot water, originally the cold water in the pipeline is just by opened magnetic valve, cold water pipes has been got back to water heater. like this, just can finish the cold water replacement process in the hot water pipeline. the cold water pipes of this moment has just become the special-purpose return pipe of closed circuit, when pump stops, closed electromagnetic valve, the hot and cold water pipeline is not communicated with thereupon yet, hot and cold water tap just can normally use, all hot water taps can both emit instant hot water-certainly, when circulating pump moves, can not influence the normal use of hot and cold water tap substantially;

2, when several hot water taps be radial the connection with water heater, be that each tap all is directly logical water heater, the hot water pipeline in the villa for example, generally all be that water heater is contained in bottom, and the hot water pipeline of each layer all is straight-through water heater, so, can be contained in the water heater next door to circulating pump, and last hot water tap who needs only at each layer has located to install a magnetic valve and control box, certainly, in control box, also remote-controlled launcher to be arranged, with the circulating pump of control far away from the water heater side.Perhaps control the operation of circulating pump with the current remote control mode, the principle of current remote control is: serial connection one little water pump between cold and hot tap, the circulating pump switch places automatic catch, when little water pump and magnetic valve are opened simultaneously, promptly in closed circuit, produce a weep that is enough to start circulating pump, circulating pump is moved automatically.Finish when the cold water replacement process, do not have current in the closed circuit, circulating pump stops automatically; Open the hot water tap when beginning just commonly used hot water, circulating pump can start again automatically, and the pump of this moment is exactly a pure booster pump;

3, control mode: can be divided into temperature controller control and manually control automatically.On the panel of control box, have manually and automatic change-over.(1) when using automated manner, as long as set the upper and lower limit temperature, circulating pump just can be lower than down work automatically in limited time in temperature, when ducted cold water is replaced by hot water, temperature probe detects hot water, and when making temperature controller reach ceiling temperature, circulating pump is just out of service automatically.Cool off gradually when ducted water temperature, when being lower than the lower limit temperature of setting, circulating pump is started working again, so moves in circles, and ducted water temperature can be remained on our the desired temperature; (2) when using manual mode, must all to press the trigger switch of operation at every turn, make circulating pump work, and the length of running can decide in two ways: a) use time switch, both can be with the time switch of simple Mainspring type, also can like this, just can indiscriminately ad. as one wishes control the running time of circulating pump with the electric timing switch of numeral demonstration according to each hot water tap's cold water time swap.B) hand switch and temperature controller are together in series, press trigger switch after, circulating pump is started working, and after a period of time, as long as temperature controller detects hot water, just cuts off the power supply of circulating pump automatically.Certainly, this mode of closing can be moved when hot water arrives last hot water tap, also can set short time and then not close (for example be not that last that tap uses hot water, but middle certain tap hot water) by time switch at hot water;

4, the composition of control box: form by temperature controller, relay, socket, change-over switch, trigger switch, time switch, remote control switch etc.;

5, to the requirement of pipeline rout and power supply: if new finishing, so, can make the trend of hot water pipeline more meet the requirement of closed circuit, promptly should each hot water tap is short as much as possible to the arm of trunk line, in other words, hot water is responsible for should directly come the hot water tap back, arm only is as short as just the hot water tap can be installed with a threeway.And tackle all hot water pipelines and all take insulation measure (with thermal insulation casing or foam).In addition, in the end a hot water tap locates to arrange a supply socket, so that the power taking of control box;

If 6 dash to drench tap be last hot water tap, then control box and magnetic valve can be connected as a single entity, carry out waterproof measure, directly replace cold and hot tap to be installed to metope, again cold and hot tap is installed on the panel of control box, circulating pump is installed in the water heater place, the promptly remote-controlled hot water circuit process of finishing.
