Abstract
The utility model relates to a solar energy water heater automatic water supply device, comprising a water tank whose bottom is provided with a connection pipe for water tank water inlet, characterized in that a floating ball is installed in the water tank, a floating ball handle connected with the floating ball traverse out the connection pipe for water tank water inlet, bottom of the floating ball handle is connected with a plunger which is a cylinder body with large one end and small another end, centre of the plunger is provided with channel communicated up and down, a plunger sleeve is provided outside the plunger, upper end of the plunger sleeve is connected with the connection pipe for water tank water inlet, sidewall is provided with a connection pipe for plunger sleeve water inlet, the plunger sleeve water inlet on the connection pipe for plunger sleeve water inlet is corresponding to the plunger; the device drives the plunger to open, close the plunger sleeve water inlet mainly by the floating ball which moves upwardly and downwardly along the change of water quantity in the water tank, therefore realizing automatic water supply and solving the difficulty that the water supply of the solar energy water heater is changed from manual control to mechanical automatic control.
Description
Technical field
The utility model relates to a kind of solar water heater automatic water supply device, can supply water for solar water heater timely automatically.
Background technique
Existing water-heater water tank water inlet is taken over, be directly to be connected on the water pipe of tap water, a manual control valve arranged, that is to say the water yield of replenishing in the solar water heater water tank indoor, need artificial control, so not only inconvenience but also cause lack of water easily or the overfill spilling water.
Summary of the invention
The purpose of this utility model provides a kind of just need not artificially control can replenish the solar water heater automatic water supply device of the water yield in the solar water heater water tank.
The utility model is achieved through the following technical solutions: a kind of solar water heater automatic water supply device, comprise water tank, the bottom of water tank is provided with the water tank water inlet and takes over, characteristics are, ball float is installed in the water tank, the floating ball handle that is connected with ball float is taken over from the water tank water inlet and is passed, its bottom is connected with plunger, plunger is the little cylindrical body of the big the other end of an end, the center is provided with the duct of up/down perforation, is provided with plunger bushing outside plunger, and the upper end of plunger bushing is taken over the water tank water inlet and is connected, sidewall is provided with the plunger bushing water inlet and takes over, and the plunger bushing water inlet on the plunger bushing water inlet is taken over is corresponding with plunger.
The utility model simple structure, cost is low, behind this device of protosun energy water heater fit on, has saved return pipe, and the cost of whole like this solar water heater can not increase, and importantly its water supply has realized automatically in time, and is full without flowing over.
The utility model concrete structure is provided by following examples and accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 ball float, 2 floating ball handles, 3 plunger bushings, 4 plungers, 5 water tank water inlets are taken over, and 6 plunger bushing water inlets are taken over, 7 plunger bushing water inlets, 8 ducts, 9 water tanks.
Embodiment
Referring to Fig. 1, the utility model comprises the ball float 1 that is installed in the water tank 9, and the other end that is connected the floating ball handle 2 on the ball float 1 is connected with plunger 4.The structure of plunger 4 be the little cylindrical body of the big the other end of an end (as shown in the figure, plunger 4 is up-thin-low-thick structure), there is the duct 8 of up/down perforation at the center, outside plunger 4, be provided with plunger bushing 3, the upper end of plunger bushing 3 is fixed on the water tank water inlet and takes on 5, sidewall is provided with the plunger bushing water inlet and takes over 6, and the plunger bushing water inlet 7 that the plunger bushing water inlet is taken on 6 is corresponding with the position of plunger 4, and the water pipe of tap water is installed in the plunger bushing water inlet and takes on 6.
During use, ball float 1 moves up and down with water yield variation in the water tank 9, and its this floating ball handle 2 that moves through becomes plunger 4 passes, opens the action of plunger bushing water inlet 7, thereby finishes the effect of automatic water-supply.
Concrete working principle is as follows:
When the water yield in the solar water heater water tank reduces, water level promptly descends, ball float in the water tank since self weight and with drawdown, under the effect of ball float, it is descending that floating ball handle promotes plunger, and the slit increases between plunger and the plunger bushing like this, has opened the plunger bushing water inlet, tap water just enters water tank, makes water level rising in the water tank.When water level rises to certain position, under the ball float effect of rising with water level, the up plunger bushing water inlet of closing of plunger, water supply stops.
During plunger upward and downward, the phenomenon of step-down and supercharging can occur in the space of plunger bottom and plunger bushing bottom, this phenomenon can influence the resistance that plunger is closed the tightness of plunger bushing water inlet and increased plunger motion.In order to solve this unfavorable factor,, the plunger top and the bottom are connected, with balance pressure in plunger center drill one duct 8.
