When this automatic loading water in solar water heater and emptying set composite use, it is installed in the top of solar water heater water tank, outlet pipe stretches in the water tank, and the water supply valve of water inlet pipe and running water joins, and also is connected to a water inlet pipe emptying valve on the water inlet pipe.Hot water tube connector and hot-water valve join, and the hot water tube connector also joins by a diversion valve and running water pipe, and an air conduit and an emptying valve join.Open water supply valve, running water just by ball-cock assembly and outlet pipe, enters in the water tank.When water was full, ball float floated, and pushes lever, and ball-cock assembly is closed.In the time of will using hot water, open the diversion valve earlier, in the hot water tube connector, charge into a certain amount of water.Close the diversion valve, open hot-water valve, because siphonage, hot water will sucking-off from water tank automatically, flows out from hot-water valve.Water finishes, and closes hot-water valve.Open the emptying valve, the water in the hot-water line can be put only.Simultaneously, water supply valve is closed, open the emptying valve, the surplus water in the water inlet pipe is bled off, just can prevent that pipeline and valve are freezing.From the above, this automatic loading water in solar water heater and emptying set composite can be intake automatically, again can be when the solar water heater stop uses, with the surplus water emptying in water inlet pipe and the outlet pipe.
(4) description of drawings:
Accompanying drawing 1 is the structure chart of this automatic loading water in solar water heater and emptying set composite;
Accompanying drawing 2 is the structure chart of lever;
Accompanying drawing 3 is the structure chart of ball float;
Accompanying drawing 4 is the use principle figure of this automatic loading water in solar water heater and emptying set composite.
(5) specific embodiment:
As shown in Figure 1, this automatic loading water in solar water heater and emptying set composite comprise shell 4, water inlet pipe 10, outlet pipe 6 and the ball-cock assembly of being made up of ball float 5, valve body 11, lever 12.Valve body 11 is fixed on the madial wall of shell 4, and water inlet pipe 10 passes the sidewall of shell, links to each other with the import of valve body; The upper end of outlet pipe 6 is fixed on the center of outer casing bottom; Ball float 5 is in the top of outlet pipe 6, the free-ended below of lever 12.It also comprises a hot water fairlead 3.There is a cylindrical hole 16 (referring to Fig. 3) at the center of ball float 5, one circular hole 17 (referring to Fig. 2) is arranged on the free end of lever 12, hot water fairlead 3 passes the hole 17 on the lever free end and the hole 16 at ball float center, stretch out from outlet pipe 6 lower ends, form a gap between the outer wall of hot water fairlead 3 and outlet pipe 6 tube walls, seal by sealing ring 14 between hot water fairlead lower end outer wall and the outlet pipe lower end, one cooling water outlet 15 is arranged on the sidewall of outlet pipe 6 lower ends, there is a threeway 2 upper end of hot water fairlead 3, the lower port of this threeway and hot water fairlead 3 join, the side ports of this threeway links to each other with a hot water tube connector 9, and the upper port of this threeway and an air conduit 8 join.1 is loam cake among Fig. 1, and 13 is water tank.
As shown in Figure 4, when this automatic loading water in solar water heater and emptying set composite use, it is installed in the top of solar water heater water tank 13, outlet pipe 6 stretches in the water tank, water inlet pipe 10 joins with the water supply valve 22 of running water, also is connected to a water inlet pipe emptying valve 29 on the water inlet pipe.Hot water tube connector 9 joins with hot-water valve 24, and the hot water tube connector also joins by a diversion valve 23 and running water pipe, and air conduit 8 joins with emptying valve 28.Open water supply valve 22, running water just by the space between ball-cock assembly 11 and outlet pipe 6 and the hot water fairlead 3, enters in the water tank.After water was expired in the water tank, water entered in the shell 4, and ball float 5 floats, and pushes lever 12, and ball-cock assembly is closed.When using hot water, open diversion valve 23 earlier, in the hot water tube connector, charge into a certain amount of cold water.Close diversion valve 23, open hot-water valve 24, because siphonage, hot water will be entered hot water tube connector 9 by hot water fairlead 3 sucking-off from water tank, flows out from hot-water valve.Water finishes, and closes hot-water valve.Open emptying valve 28, the water in the hot-water line can be put only.Simultaneously, water supply valve 22 is closed, open water inlet pipe emptying valve 29, the surplus water in the water inlet pipe is bled off.Just can prevent that pipeline and valve are freezing.In addition, can also adorn a magnetic valve 21 between the low level delivery port of water tank 13 and hot water tube connector 9, this magnetic valve also can be used for adding drainage water in hot water tube connector 9 when beginning to put hot water.In addition, water level is lower in water tank, and when hot water fairlead 3 lower ends do not reach the water surface, but also opens solenoid valve puts hot water.25 is hot water outlet among Fig. 4, and 26 is running water inlet, and 27 is air intlet.
