Abstract
The utility model discloses an antifreeze device of a tap water type solar water heater, which settles a problem that the water pipe is always frozen to crack or blocked by freezing. The antifreeze device comprises a solar water tank, a water feeding short pipe, a tap water pipe, etc. The utility model is characterized in that: the water feeding short pipe is connected with a pneumatic control valve; the pneumatic valve is provided with a pneumatic control pipe and a water inlet/outlet pipe; a control waterway is connected parallelly between the water inlet/outlet pipe and the tap water pipe; the control waterway comprises a water pressure chamber, an evacuation self-closing valve, a bidirectional valve, etc; one end of the bidirectional valve is connected with the tap water pipe, and the other end is connected with a water discharge pipe. The antifreeze device of the tap water type solar water heater uses the balance of water pressure and air pressure for controlling water flowing and has the advantages of: effective evacuating the water in the water inlet/outlet pipe, preventing freezing in winter, preventing potential trouble of freezing, and settling a problem that the cold water in the water inlet/outlet pipe must be drained in water using every time. The antifreeze device of a tap water type solar water heater further has the advantages of simple structure, easy manufacturing, convenient installing, high safety, energy saving, environment protection, and facility for generalizing the solar water heater.
Description
Affiliated technical field
The utility model relates to solar water heater, relates to a kind of defroster of solar water heater or rather.
Background technology
At present, solar water heater is when user mode, and is always water-filled in the upper and lower conduit, will there be two big drawbacks in the time of in the winter time, the one, cause the part heat to run off, the 2nd, in the winter of severe cold, the water pipe of outdoor section usually by the bursting by freezing or the obstruction of freezing, causes solar water heater to use.Realize antifreeze purpose though can adopt Electric heating or outdoor water pipe is installed additional thicker methods such as insulation material, result of use can not be satisfactory.
Summary of the invention
The purpose of this utility model is to provide a kind of defroster of solar water heater, and the ponding in the emptying upper hose has solved water pipe effectively usually by bursting by freezing or icing blocking problem effectively.
The technical solution of the utility model is such, and it comprises solar water container, goes up water short tube, running water pipe etc., it is characterized in that connecting a Pneumatic valve at last water short tube, is provided with pneumatic tubes and water inlet pipe and water outlet pipe in the described Pneumatic valve; A control water route in parallel comprises hydraulic pressure storehouse, emptying self-closing valve, two-way valve between described water inlet pipe and water outlet pipe and the running water pipe; Described hydraulic pressure is provided with emptying device in the storehouse, being provided with membrane vesicle formula tubular piston in the emptying device connects one-way exhaust valve and connects the emptying self-closing valve by connecting rod, described emptying self-closing valve connects two-way valve, and described two-way valve one end connects running water pipe, and the other end connects drainpipe.
From the above, the utility model has fully utilized the multiple natural law, utilizes the balance of water, air pressure to control flowing of water, the effective water in the emptying water inlet pipe and water outlet pipe, avoid ice up in winter, eradicate the hidden danger of freezing, solved the problem that each water must drain the water inlet pipe and water outlet pipe inner cold water earlier; Simple in structure, produce easily, to be convenient to install, safety, energy-saving and environmental protection help promoting the use of of solar water heater.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1. water tank is 2. gone up the water short tube, 3. Pneumatic valve, 4. pneumatic tubes, 5. water inlet pipe and water outlet pipe, 6. running water pipe, 7. hydraulic pressure storehouse, 8. membrane vesicle formula tubular piston, 9. emptying device, 10. one-way exhaust valve, 11. connecting rods, 12. emptying self-closing valves, 13. two-way valves, 14. drainpipes.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, water short tube 2 is provided with pneumatic tubes 4 and water inlet pipe and water outlet pipe 5 by Pneumatic valve 3 of connections such as screw thread in the described Pneumatic valve 3 on solar water heater, and the mouth of pipe of described pneumatic tubes 4 and water inlet pipe and water outlet pipe 5 staggers; A control water route in parallel comprises hydraulic pressure storehouse 7, emptying self-closing valve 12, two-way valve 13 etc. between described water inlet pipe and water outlet pipe 5 and the running water pipe 6; Be provided with emptying device 9 in the described hydraulic pressure storehouse 7, being provided with membrane vesicle formula tubular piston 8 in the emptying device connects one-way exhaust valve 10 and connects emptying self-closing valve 12 by connecting rod 11, described emptying self-closing valve 12 connects two-way valve 13, described two-way valve 13 1 ends connect running water pipe 6, and the other end connects drainpipe 14.Described membrane vesicle formula tubular piston 8 also can be wrinkle formula tubular piston.Operation principle is as follows: be moved to the left two-way valve 13 as figure, promptly open running water pipe 6, close drainpipe 14, the running water of running water pipe 6 is rushed in hydraulic pressure storehouse 7, gas is compressed in the storehouse, pressure increases thereupon, one-way exhaust valve 10 is opened, the liter waterborne that compressed gas orders about in the water inlet pipe and water outlet pipe 5 enters Pneumatic valve 3, enters water tank 1 backward through pneumatic tubes 4 transition flows.In this process, membrane vesicle formula tubular piston 8 reduces because of water inlet pipe and water outlet pipe 5 suffered hydraulic pressure, under the 7 internal gas pressure effects of hydraulic pressure storehouse, rise, driving one-way exhaust valve 10 rises synchronously with connecting rod 11, after water inlet pipe and water outlet pipe 5 is drained thereupon emptying self-closing valve 12 close, emptying device 9 can be guaranteed the realization of this target, and running water stops to 7 pressurizations of hydraulic pressure storehouse.In water inlet pipe and water outlet pipe 5 and hydraulic pressure storehouse 7 air pressure balances, one-way exhaust valve 10 is closed voluntarily.Move right and close two-way valve 13, the water in the hydraulic pressure storehouse 7 flows out from drainpipe 14 automatically, in order to reusing.
In Pneumatic valve 3, unnecessary gas enters in the water tank 1, and behind hydraulic pressure and air pressure balance in the Pneumatic valve 3, water is quiet and do not let out.There is gas anhydrous in the water inlet pipe and water outlet pipe 5, just can plays antifreeze effect.Use water heater the same with normal water, the tap of fetching boiling water, water inlet pipe and water outlet pipe 5 internal gas pressures reduce to 0, and the water of water tank 1 the inside can flow out instant-heating by nature under the acting in conjunction of atmospheric pressure and gravity.
Repeat said process, can finish the function of each evacuation and anti-freezing, realization instant-heating.
