Abstract
The utility model relates to a solar water heater water tank, comprising an inner layer water storage bucket, an outer layer heat insulation bucket, and a foaming insulation layer arranged between the water storage bucket and the heat insulation bucket, which is characterized in that, a hollowed down prepared hole is arranged at the bottom of the water storage bucket; a pressure bearing piece and a waterproof loop are arranged in the prepared hole; the pressure bearing piece and the foaming insulation layer are integrated into one body; sealing is realized by the obstruction corresponding to the pressure bearing piece or an electric heater. The utility model has the advantages that, the manufacture of the prepared hole of the inner layer water storage bucket of the utility model does not require welding working procedure, so the microstructure of the prepared hole is perfectly maintained, corrosion is not likely to take place, and the service life of the water tank is prolonged; as the hollowed down prepared hole is arranged at the bottom of the water storage bucket, the pollution discharge of the water tank is thorough; as the pressure bearing piece and the waterproof loop are arranged in the prepared hole, the prepared hole has strong pressure bearing capability, and leakage is avoided.
Description
Technical field:
The utility model relates to technical field of solar water heaters, particularly a kind of solar water heater water tank.
Background technology:
At present, solar water heater water tank roughly comprises: internal layer water butt, outer heat-preserving container are provided with insulating foam layer between water butt and heat-preserving container.The water tank that has is provided with the preformed hole that is used for blowdown.The making of preformed hole sealing is generally the internal thread welding, joins the sealing of threaded bar screw outward.Or welded flange on the internal layer water butt is being arranged, add the sealing of sealing ring and flange face again.Such as all welding sequences that all needs, inner bag because its metallographic structure goes to pot, makes that inner bag is easy to be corroded by after welding, and causes the seepage phenomenon.Reduce the service life of solar water heater.Moreover, the processing technology complexity of above-mentioned water-heater water tank preformed hole, the cost height, and can not reach the effect of the complete blowdown of water tank.
Summary of the invention:
For solving above deficiency, the utility model proposes that a kind of blowdown is thorough, easy to make, bearing capacity is strong, the solar water heater water tank of long service life.It comprises: internal layer water butt, outer heat-preserving container are provided with insulating foam layer between water butt and heat-preserving container; Described water butt bottom is provided with the preformed hole with following concavity, is provided with pressure part and water proof ring in preformed hole, and pressure part and insulating foam layer link into an integrated entity, and by blocking or the electric heater sealing with pressure part is corresponding.Internal layer water butt preformed hole of the present utility model is made and be need not welding sequence, and its metallographic structure remains intact, and is not perishable, prolongs the service life of water tank.Because the water butt bottom is provided with the preformed hole with following concavity, makes that the water tank blowdown is thorough.Be provided with pressure part and water proof ring in the preformed hole, make that the preformed hole bearing capacity is strong, can seepage.
In the utility model, described water butt bottom lower concave part becomes a flanging, and flanging is provided with its corresponding water proof ring, blocks correspondingly with water proof ring, and the obstruction bottom is provided with bottom.Preformed hole is simple in structure, and is easy to make.
Description of drawings:
Fig. 1 is the utility model water tank schematic diagram.
Fig. 2 is that the utility model water tank preformed hole is installed the obstruction enlarged diagram.
Fig. 3 is that the utility model water tank preformed hole is installed the electric heater enlarged diagram.
The specific embodiment:
As Fig. 1, Fig. 2, shown in Figure 3, solar water heater water tank of the present utility model comprises: internal layer water butt 1, outer heat-preserving container 2 are provided with insulating foam layer 3 between water butt and heat-preserving container; Be provided with the preformed hole 4 with following concavity bottom the water butt, be provided with pressure part 5 and water proof ring 6 in preformed hole, pressure part 5 and insulating foam layer 3 link into an integrated entity, and seal with pressure part 5 corresponding obstructions 7 or electric heater 8 by one.Water butt bottom lower concave part becomes a flanging 9, and flanging is provided with an its corresponding water proof ring 6, and obstruction 7 is corresponding with water proof ring 7, blocks the bottom and is provided with bottom 10.
Claims (2)
1, a kind of solar water heater water tank comprises: internal layer water butt, outer heat-preserving container are provided with insulating foam layer between water butt and heat-preserving container; It is characterized in that: described water butt bottom is provided with the preformed hole with following concavity, is provided with pressure part and water proof ring in preformed hole, and pressure part and insulating foam layer link into an integrated entity, and by blocking or the electric heater sealing with pressure part is corresponding.
2, solar water heater water tank according to claim 1; It is characterized in that: described water butt bottom lower concave part becomes a flanging, and flanging is provided with an its corresponding water proof ring, blocks correspondingly with water proof ring, and the obstruction bottom is provided with bottom.
