Abstract
The utility model provides a solar water heater provided with a water supplying-draining pipe emptying device. The solar water heater comprises a solar water tank; an inverted U-shaped water supplying-draining pipe is in inserted connection with the bottom of the solar water tank; the upper end of the inverted U-shaped water supplying-draining pipe is arranged in the solar water tank; and the water outlet end of the inverted U-shaped water supplying-draining pipe, which is outside the solar water tank, is connected with a water supplying-draining pipe; a water valve is arranged at the lower end of the water supplying-draining pipe; a pressure-bearing air change barrel is connected with the side surface of the water supplying-draining pipe; and a valve is arranged between the pressure-bearing air change barrel and the water supplying-draining pipe. The solar water heater has the beneficial effects that water in the pipes of the solar water heater can be emptied when not in use, so as to prevent the problem of pipe freezing and blockage below the temperature of 0 DEG; and besides, the solar water heater is safe during use.
Description
Technical field
The utility model relates to a kind of solar water heater, especially relates to a kind of solar water heater with water-supply pipeline evacuation device.
Background technology
At present, the water in the known solar water heater upper and lower conduit pipe in winter easily freezes, and has hot water also can not use hot water because of pipeline freezes in the solar water heater.Usefulness generally is to add the ribbon heater on pipeline now.But make the ice-out in the pipeline that following defective be arranged with the heat tape water back: 1) fire easily the ribbon heater, 2) use dangerous.
The utility model content
The technical problems to be solved in the utility model provides a kind of solar water heater with water-supply pipeline evacuation device; This solar water heater solves the normal requirement of water up and down of solar pipe subzero with the tube emptying method of Purely mechanical, and safe in utilization.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: it comprises solar water container, the anti-U type upper and lower conduit of pegging graft in the bottom of this solar water container, this anti-U type upper and lower conduit upper end is in solar water container, and water outlet end is outside solar water container; Described anti-U type upper and lower conduit water outlet end connects upper and lower conduit, and the lower end of this upper and lower conduit is established and used penstock; The side of described upper and lower conduit is connected with pressure-bearing ventilation bucket, is provided with valve between this pressure-bearing ventilation bucket and the upper and lower conduit.
Further, a described pressure-bearing ventilation bucket bottom is provided with bleeder cock.
Further, described upper and lower conduit with pressure-bearing ventilation bucket be connected by threeway and communicate.
Further, the valve between described pressure-bearing ventilation bucket and the upper and lower conduit is a three-way valve.
Further, described solar water container is provided with heat-insulation layer outward.
Further, be provided with silica gel sealing ring between described anti-U type upper and lower conduit and the solar water container.
The beneficial effects of the utility model are: the pipeline inherence that can make solar water heater is not realized the purpose of emptying during water, prevents the problem of temperature subzero pipe freezeup, and is simultaneously safe in utilization.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to shown in Figure 1, the utility model comprises solar water container 1, this solar water container 1 outer heat-insulation layer 2 that is provided with; The anti-U type upper and lower conduit 3 of pegging graft in the bottom of this solar water container 1, these anti-U type upper and lower conduit 3 upper ends are in solar water container 1, and water outlet end is outside solar water container 1; Described anti-U type upper and lower conduit 3 water outlet ends connect upper and lower conduit 4, and establish with penstock 5 lower end of this upper and lower conduit 4; The side of described upper and lower conduit 4 is connected with pressure-bearing ventilation bucket 6, is provided with three-way valve 7 between this pressure-bearing ventilation bucket 6 and the upper and lower conduit 4;
Described pressure-bearing ventilation bucket 6 bottoms are provided with bleeder cock 61;
Described upper and lower conduit 4 and pressure-bearing ventilation bucket 6 is connected by threeway 41 and communicates;
Be provided with silica gel sealing ring 8 between described anti-U type upper and lower conduit 3 and the solar water container 1.
Operation principle of the present utility model is as follows: open during water with penstock 5, water is done under the time spent spontaneous current at gravity.Do not close during water with penstock 5, opening three-way valve 7 connects upper and lower conduit 4 and pressure-bearing ventilation bucket 6, utilize the of poor quality of water and air, water flows into pressure-bearing ventilation bucket 6, displace the air in the bucket, air makes progress away along upper and lower conduit 4, forms pressing to anti-U type upper and lower conduit 3 and downward current, utilizes air to upward pressure water is no longer flowed down.Realize that in the pipeline be the purpose of air entirely.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
