Abstract

The utility model relates to a solar water heater, in particular to an intelligent antifreeze draining device of a solar water heater pipeline. The intelligent antifreeze draining device comprises a water tank and a water inlet and outlet pipe, wherein the water inlet and outlet pipe is inserted on the water tank, and the outer surface of the water tank is covered by a heat insulation layer. The intelligent antifreeze draining device is characterized in that the water inlet and outlet pipe is inserted into an inner cavity of the water tank from the lower end of the water tank, the upper end of the water inlet and outlet pipe extends to the top of the inner cavity of the water tank, the lower end of the water inlet and outlet pipe is connected with a tee, other two joints of the tee are respectively connected with an intermediate pipe and an outer pipe, an electromagnetic valve is connected to the intermediate pipe in series, a sleeve is sleeved outside the water inlet and outlet pipe, the lower end of the sleeve is sealed, the upper end of the sleeve is inserted on the water tank and communicated with the inner cavity of the water tank, and the intermediate pipe is communicated with the sleeve. A water feeding and discharging device of the solar water heater is simple in structure and accordingly avoids increasing construction cost. Even in cold winter, the intelligent antifreeze draining device is capable of draining water in water pipes so as to prevent the water pipes from being frozen.

Description

The antifreeze emptier of a kind of solar energy water heater pipe intelligence

Technical field

The utility model relates to a kind of solar water heater, the antifreeze emptier of especially a kind of solar energy water heater pipe intelligence.

Background technology

In order to reduce the cost of producing and installing, the upper and lower water of prior solar water heater mostly adopts same water pipe, indoor switch by valve on water under the hydration.Water is arranged in the upper and lower conduit of this water supply and drainage mechanism all the time,,, still can't avoid water pipe to be frozen in even the possibility of bursting by freezing in the winter of cold although construction the time all can be installed heat-insulation layer additional in the outside of water pipe usually.

Summary of the invention

The utility model provides a kind of solar water heater water supply and drainage mechanism that freezes water pipe of not being afraid of at the problems referred to above.

For achieving the above object, the technical scheme that the utility model adopted is:

The antifreeze emptier of a kind of solar energy water heater pipe intelligence described in the utility model comprises water tank and the water inlet pipe and water outlet pipe that is inserted on the water tank, the water tank outer surface is coated with heat-insulation layer, it is characterized in that: described water inlet pipe and water outlet pipe inserts the inner chamber of water tank from the lower end of water tank, the upper end of water inlet pipe and water outlet pipe extends to the top of water tank cavity, the lower end of water inlet pipe and water outlet pipe connects threeway, two end interfaces in addition of described threeway connect intervalve and outer tube respectively, are in series with magnetic valve on the intervalve; The outside at outlet pipe is set with sleeve pipe, the lower end closed of this sleeve pipe, and the upper end of sleeve pipe is inserted on the water tank and with the inner chamber of water tank and is communicated with, and intervalve is communicated with sleeve pipe.

The outside of described magnetic valve and threeway is coated with heat-insulation layer.

After adopting technique scheme, this solar water heater water supply and drainage mechanism is simple in structure, does not increase construction cost.In the winter of cold, the water in the water pipe can be emitted, thereby prevent to freeze water pipe.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model.

The specific embodiment

As shown in Figure 1, the antifreeze emptier of a kind of solar energy water heater pipe intelligence described in the utility model, comprise water tank 1 and the water inlet pipe and water outlet pipe 2 that is inserted on the water tank 1, water tank 1 outer surface is coated with heat-insulation layer 3, described water inlet pipe and water outlet pipe 2 inserts the inner chamber of water tank 1 from the lower end of water tank 1, the upper end of water inlet pipe and water outlet pipe 2 extends to the top of water tank 1 inner chamber, the lower end of water inlet pipe and water outlet pipe 2 connects threeway 4, two end interfaces in addition of described threeway 4 connect intervalve 5 and outer tube 6 respectively, be in series with magnetic valve 7 on the intervalve 5, magnetic valve 7 adopts voltage to be less than or equal to 36 volts alterating and direct current magnet valve, and security is good; Be set with sleeve pipe 8 in the outside of outlet pipe 2, the lower end closed of this sleeve pipe 8, the upper end of sleeve pipe 8 is inserted on the water tank 1 and with the inner chamber of water tank 1 and is communicated with, and intervalve 5 is communicated with sleeve pipe 8.In addition, can coat heat-insulation layer, can improve heat insulation effect on the one hand, emptier can be made independently parts separately on the other hand, be convenient to production and selling in the outside of magnetic valve 7 and threeway 4.

Usually in the time of normal the use, magnetic valve 7 is in open mode.This moment, upper and lower water operation was identical with the regular solar water heater.

In the winter of cold, after the upward intact water, be frozen in order to prevent the water in the outer tube 6, need be no the time with the water emptying in the outer tube 6.Can close magnetic valve 7 this moment, simultaneously at the indoor drainage valve of opening, and so just can be with the water emptying in the outer tube 6.When on the needs water time, get final product at the indoor water supply valve door of opening.Use the hot water in the water tank if desired, will open drainage valve more earlier opening magnetic valve 7, the water in the water tank 1 just can flow out by sleeve pipe 8, magnetic valve 7, threeway 4, outer tube 6.
