Description
Technical field
This invention belongs to the category of solar water heater corollary equipment.
Background technology
Now, non-pressure solar water heater because of its Heat-collecting effect good, steady performance, occupies the larger market share.Its shortcoming is that attemperater is placed in outdoor, upper and lower conduit road easy frozen block in the winter time, thus cause solar water heater in the winter time microthermal climate can not utilize.For this situation, conventional solution utilizes electric-heating belt to thaw, and the shortcoming that electric-heating belt thaws is consume electric power and possibility short-circuit fire, bring potential safety hazard, moreover thawing time is longer to user.Other thawing mode also has various electric atmospheric relief valve, and its practical function is not fine, and its deadly defect is because needs are automatically controlled, aging and out of control along with electric fittings, and defect is easily out of control and service life is shorter, and assembling is inconvenient.
Summary of the invention
For the defect that above-mentioned non-pressure solar water heater not easily thaws winter, spy devises this solar water heater overhead emptier, its mentality of designing is: utilize siphon principle that the delivery port of solar water heater is arranged on top, peak assembles emptying module, and the method utilizing air inlet to destroy negative pressure carries out pipeline evacuation.
Solution of the present invention is: solar water heater overhead emptier is made up of built-in pipe, emptying module, upper and lower conduit road, air inlet pipeline, lower water valve, water supply valve, intake valve; It is characterized in that: built-in pipe one end is inserted by the top of attemperater, the other end is connected with the built-in pipe interface of emptying module; One end, upper and lower conduit road is connected to the upper and lower conduit interface of emptying module, and the other end connects water supply valve and lower water valve, and water supply valve is connected with pressure water source capsule road; One end of air inlet pipeline connects the air inlet pipe interface of emptying module, and the other end connects intake valve.
Emptying module as above comprises three-way body, float chamber.Three-way body comprises upper and lower conduit interface, built-in pipe interface and float chamber interface; Float chamber comprises float chamber housing, three-way body interface, air inlet pipe interface, float.Three-way body and float chamber connect into emptying module by float chamber interface and three-way body interface.
The upper and lower conduit interface of the three-way body in emptying module described above, built-in pipe interface and float chamber interface can exchange according to the difference of installation site, guarantee that float chamber is in the peak of emptying module.
Operation logic of the present invention is: emptying module is assembled to the top of heat-preserving water tank for solar water heater by built-in pipe, and built-in pipe is inserted into bottom attemperater; Air inlet pipeline and one end, upper and lower conduit road and emptying model calling, the other end imports and indoorly also assembles water supply valve, lower water valve and intake valve; Water supply valve is connected with pressure water source capsule road.Intake valve and lower water valve only need be opened time emptying, air enters emptying module by intake valve and air inlet pipeline, and the negative pressure in emptying module is reduced, and a part of water is back in attemperater, part water is discharged by upper and lower conduit road and lower water valve, reaches emptying object.If when needing to use hot water, only need close lower water valve and intake valve, open water supply valve, after making upper and lower conduit road fill water, close water supply valve, open lower water valve, hot water will flow down, and is utilized.On solar water heater during water, close lower water valve and intake valve, open water supply valve, pressure water source is injected in the attemperater of solar water heater by water supply valve, upper and lower conduit road, emptying module, built-in pipe; If hydraulic pressure is comparatively large, water can enter float chamber, and the float in float chamber can raise along with water level and float blocking air inlet pipe internal orifice, thus avoids water in the backflow of air inlet pipeline.
This beneficial effect of the invention is: 1 this invention does not have the electric control system of very complicated, does not have electric energy loss and electric leakage risk.2 these inventions are rational in infrastructure, and Purely mechanical operates, simple and practical.
