Abstract
The utility model relates to a kind of water-saving anti-freezing apparatus on solar water heater, it is characterized in that a pulsometer is connected with solar energy water-supply-pipe by air-pressure duct, air-pressure duct is installed with check valve.Its processing technology is simple, with low cost, and simple installation is easy to use.Not only be applicable to the new solar water heater installed, be also applicable to the transformation to the solar water heater installed and used.
Description
Technical field
The utility model relates to a kind of water-saving anti-freezing apparatus on solar water heater.
Background technology
Solar water heater industry is through development for a long time, with its energy-conserving and environment-protective facilitate durable accept by vast consumer, but solar water heater also has its weak point: during as used hot water at every turn, always first ducted for solar energy water-supply-pipe residual water to be bled off, hot water just slowly flows out, not only consuming time, and wasted the water of a lot of cleaning; Winter makes outdoor temperature is low, easily makes the residual water in solar energy water-supply-pipe yard piping freeze, and bursting by freezing yard piping." heating tape " and " exhaust-valve " that prior art is put on market, tracing it to its cause is because " heating tape " power greatly takes electricity very much, and dangerous easy generation fire, there is very large potential safety hazard." exhaust-valve ", being finished hot water after at every turn, first being closed the valve of aqueduct in water tank, then will be bled off the water in water-supply-pipe, carry out the water in emptying pipe with this, thus reach antifreeze object.So not only wasted water, and exhaust-valve install because of solar water heater yard piping move towards different problem, troublesome poeration.Always have ponding row at the low-lying place of pipeline unclean, therefore also really emptyingly can not play antifreeze object.
Summary of the invention
Goal of the invention of the present utility model, to provide one can after finishing using exactly, hot water residual in the aqueduct of solar water heater is fed back in the water tank of solar water heater, water-saving object can be reached, can make again to be in anhydrous state in aqueduct, can prevent from freezing and bursting by freezing aqueduct when low temperature.Technical solution of the present utility model is such; A kind of solar water heater water-saving anti-freezing apparatus, is characterized in that a pulsometer is connected with solar energy water-supply-pipe by air-pressure duct, air-pressure duct is installed with check valve.
。After using, close all pipeline valves, open pulsometer, pulsometer is pressurizeed in solar energy water-supply-pipe by pipeline, and under the driving of pressure, the residual water in solar energy water-supply-pipe refluxes in solar storage water tank.After the residual water in solar energy water-supply-pipe is emptying, closing pulsometer, is just air in solar energy water-supply-pipe.Use the invention has the beneficial effects as follows; Use front water-supply-pipe emptying be air, both can using water wisely, can prevent again the residual water in solar energy water-supply-pipe in winter from freezing and bursting by freezing aqueduct.Its processing technology is simple, with low cost, and simple installation is easy to use.Not only be applicable to the new solar water heater installed, be also applicable to the transformation to the solar water heater installed and used.
Accompanying drawing explanation
Accompanying drawing 1 is schematic diagram of the present utility model.
Detailed description of the invention
In Fig. 1, pulsometer 11 is connected by the aqueduct 10 of the air-pressure duct 2 with solar water heater that are installed with check valve 8, and pulsometer 11 is connected with gauge tap 5 by power line 6.Can also by communicating pipe 3 setting pressure table 4 and pressure-reducing valve 7 on the air-pressure duct 2 of pulsometer 11, to observe pressure condition and the too high pressure of release.After using solar energy, all valves of water consumption device 1 in close chamber, pulsometer 11 is started by gauge tap 5, the pressure air that pulsometer 11 produces is by the aqueduct 10 of the air-pressure duct 2 with solar water heater that are installed with check valve 8, the residual water in the aqueduct 10 of solar water heater is made to turn back in the storage tank 9 of solar water heater, after closing pulsometer 11, only remaining by airtight air in the aqueduct 10 of solar water heater, get final product using water wisely, also can prevent frost crack pipe.
The air-pressure duct 2 that pulsometer 11 connects can connect with screw thread, bonding, welding manner with the aqueduct 10 of solar water heater foremost or Anywhere at indoor hydrophone 1.
