Abstract

The utility model discloses a solar press-resisting type heat pump water tank, which mainly comprises an internal barrel body (3), an upper and lower end cap (2), a heat insulation layer (4), an external barrel (5) and a heat exchanger (14), wherein the heat exchanger (14) is arranged in the internal barrel body (3), and is connected with a medium inlet and a medium outlet (10, 9) which are arranged on the internal barrel body (3), a cold water interface (12) is arranged on the internal barrel body (3), a drain (13) is arranged on the bottom portion of the lower end cap (2), the upper and lower end cap (2) is a knoll type arc end cap, the internal barrel body (3) is welded with the upper and lower end cap (2) through a necking socket joint, and the top portion of the upper end cap (2) is provided with a relief valve. The heat pump water tank solves the problems that the pressure resistance is low, and users which are close to or surpasses the water tank water level can not normally use the water tank and the like, and has the advantages of simple and reasonable structure, high pressure resistance, safe and reliable usage and high water resource utilization rate, which can meet the requirements of users with various pressure differences.

Description

Solar energy pressure-bearing type heat pump water tank

Technical field

The present invention relates to a kind of solar water container, particularly a kind of pressure-bearing type solar heat pump water tank.

Background technology

Along with the development of society and the progress of science and technology, the application of solar energy also more and more is subjected to liking of users; In solar energy heat collector, water tank is absolutely necessary as a kind of accumulation of energy and water storage device, traditional solar heat pump non-bearing type water tank mainly is made up of casing, insulation material and shell, wherein casing generally with stainless steel flush end lid and the single entry container that ladle body is welded, is provided with spout hole on top, casing side again; The weak point that this structure exists mainly contains: the one, and water will flow out by spout hole when the water tank middle water level surpasses spout hole, causes the waste of the water resource and the energy; The 2nd, when user's height near or when surpassing cistern water level, do not having under the prerequisite of booster pump, because of the pressure of water tank can't meet the demands, cause the little or anhydrous situation of user's water yield; The 3rd, the water tank bearing capacity is poor.For this reason, many scientific research institutions, manufacturer and knowledgeable people have constantly carried out R and D at the problems referred to above that exist, and do not improve way preferably but have as yet so far.

Summary of the invention

For overcoming the disadvantage of above-mentioned existence, the purpose of this utility model provide a kind of simple and reasonable, pressure-bearing is high, safe and reliable, water utilization rate is high, can satisfy the Solar energy pressure-bearing type heat pump water tank of different pressure reduction user needs.

The technical scheme that its technical problem that solves the utility model adopts, this water tank is mainly by interior bucket ladle body, end cap, heat-insulation layer, outer bucket, heat exchanger are formed up and down, heat exchanger is arranged in the interior bucket ladle body, and be arranged in the medium import and export of bucket on the ladle body be connected, an interior bucket ladle body is provided with the cold water interface, the bottom of bottom end cover is provided with sewage draining exit, described end cap up and down is a mound type cambered surface end cap, interior bucket ladle body is with end cap is fixing by reducing socket welding up and down, and the top of upper end cover is provided with relief valve.

As the further preferred version of the utility model, a described interior bucket ladle body is provided with circulation import and loop exit.

As the further preferred version of the utility model, a described interior bucket ladle body is provided with hot water outlet.

As the further preferred version of the utility model, a described interior bucket ladle body is provided with the thermometric interface.

After adopting technique scheme, following advantage is arranged: the one, up and down end cap adopts the mound type cambered surface end cap can dispersive pressure, end cap and interior bucket ladle body are fixing by reducing socket welding up and down, increased the bearing capacity of water tank greatly, can guarantee water tank operate as normal under 0.6MPa pressure, make near or the user that surpasses cistern water level can both normally use; The 2nd, installing and using of relief valve can guarantee that the user is safe and reliable; The 3rd, owing to can not produce overflow, the water utilization rate height.
