Abstract
The utility model relates to an automatically controlled water charging device for a solar water heater, which is composed of a control box (1), a ball float, a traction rope (3), a pressure difference automatically controlled valve (4), a hot water switch (5), a cold water switch (6), and a flow blocking valve (7). The bottom of the control box (1) is communicated with the bottom of a water storage tank of a solar water heater; when water is charged, the switch is closed, the switch (6) is opened, and cold water goes into the control box (1) and the water storage tank; when the inside of the control box is filled with water, the ball float drives the traction rope to pull a valve core of the pressure difference automatically controlled valve, a water inlet channel is closed, and the charge of water is automatically stopped; when hot water is used, closing the cold water switch (6) and opening the hot water switch (5) are just needed; the temperature of the hot water can be regulated by properly opening the cold water switch (6).
Description
The utility model relates to a kind of solar water heater automatic control priming apparatus, (to call the automatic control priming apparatus in the following text).Solar water heater just progressively enters into family, especially in China, the south, use more extensive.Prior solar water heater adds water and exists certain shortcoming, need manually monitor water return outlet when adding water, waits until to see and could judge when water return outlet emits water that water fills it up with always, will add taps again and close, so not only inconvenience but also lose time.The automatic control priming apparatus of a kind of solar water heater that the utility model is designed, it can overcome above-mentioned shortcoming, this device has adopted differential pressure automatic control valve and resistance valve, can add water at any time with people's wish, automatically stop to add water after filling it up with, the temperature that can regulate hot water again at any time when using hot water, not only convenient but also save time.
The purpose of this utility model is achieved in that the automatic control priming apparatus is made up of control cabinet, cold water switch, hot-water switch, resistance valve.The bottom of control cabinet is communicated with (also the two can be made of one) with the water tank bottom of solar water heater.When water in the water tank of solar water heater uses up when maybe needing to add water, close hot-water switch earlier, open cold water switch again, cold water promptly enters in control cabinet and the water tank, when water is filled it up with in the control cabinet (water also has been full of in the water tank), the ball float in the control cabinet floats, and affects the differential pressure automatic control valve core by pull rope, close intake tunnel, stop to add water.When needing to use hot water, close cold water switch, open hot-water switch and can use hot water.Too high as the hot water water temperature, can suitably open cold water switch and regulate.Hot water when resistance valve has guaranteed that the main-supply road cuts off the water in the water tank can not run off, and has prevented that other from using hot water with tap yet, guarantees abundant shower water.
Fig. 1: the automatic control priming apparatus holds intention.Fig. 2: differential pressure automatic control valve profile.Fig. 3: resistance valve profile.
Below in conjunction with accompanying drawing, the automatic control priming apparatus is described in detail:
By Fig. 1, the automatic control priming apparatus by control cabinet (1), ball float (2), pull rope (3), differential pressure automatic control valve (4), hot-water switch (5), cold water switch (6), resistance valve (7), form.The bottom of control cabinet (1) and the water tank of solar water heater bottom is communicated with, also can be made of one the water tank of control cabinet (1) and solar water heater in (among the figure shown in the double dot dash line).Above-mentioned each parts (showing as Fig. 1) are communicated with main-supply road (8), and all are higher than other usefulness tap (9).By Fig. 2, differential pressure automatic control valve (4) is made up of valve gap (10), valve body (11), spool (12), valve seat (13), guide post (14).By Fig. 3, resistance valve (7), form by valve gap (15), valve body (16), spool (17).
By Fig. 1, when adding cold water, close hot-water switch (5), open cold water switch (6), cold water promptly by main-supply road (8) through resistance valve (7), switch (6), differential pressure automatic control valve (4) enters in control cabinet (1) and the solar energy water tank, by Fig. 1, Fig. 2, when water is filled it up with in the control cabinet (1) (water has also been filled it up with in the water tank), ball float (2) floats, and drives pull rope (3), pulling guide post (14), mention spool (12),, be adjacent to valve seat (13), close intake tunnel, stop to add water.When using hot water, close cold water switch (6), open hot-water switch (5), get final product, too high as the hot water water temperature, can suitably open cold water switch (6) regulates, water uses up or spends a part in water tank, in the time of need adding water, closes hot-water switch (5) earlier, open cold water switch (6) again, promptly add water automatically.After water in the control cabinet (1) is filled it up with, promptly stop to add water automatically, by Fig. 1, Fig. 3, resistance valve (7) is installed in other with between tap and the cold water switch, when opening cold water switch (6) when adding cold water, spool (17) lifts and allows cold water by entering in the water tank, and when main-supply road (8) when cutting off the water, spool (17) falls and stoped the hot water in the water tank to run off.Prevented also simultaneously that other from using hot water with tap (9).
Compared with prior art, this automatic control priming apparatus has the following advantages:
1, realized too can water heater adding the automation of water.
2, adopted differential pressure automatic control valve and resistance valve coupling to use, dependable performance, the life-span is long.
3, structure is little, and cost is low.
Claims (4)
1, a kind of solar water heater automatic control priming apparatus, form by control cabinet, differential pressure automatic control valve, resistance valve etc., it is characterized in that the ball float in the control cabinet is connected by the spool of pull rope with the differential pressure automatic control valve, differential pressure automatic control valve, resistance valve are connected with annexes such as water pipe, switches.
2, solar water heater automatic control priming apparatus according to claim 1 is characterized in that the spool of differential pressure automatic control valve is installed in the type blind hole of garden, and into water duct is arranged around the blind hole.
3, solar water heater automatic control priming apparatus according to claim 1 is characterized in that: resistance valve is installed in the hot water or cold water with between the tap.
4, solar water heater automatic control priming apparatus according to claim 1 is characterized in that: control cabinet is made of one with the water tank that hinders very much the energy water heater, forms the solar water heater of band automatic control priming apparatus.
