Description
Technical field:
The utility model is relevant with gas heater antiscale burn-proof device.
Background technology:
According to convention as can be known, high-temperature water is less scaling under quick flow regime, and under static state, when temperature is promptly beginning to generate incrustation scale more than 60 ℃.After general gas heater is flame-out, the waste heat of heat exchanger can make the water that is trapped in the pipeline heat up sometimes hot even up to more than 60 ℃, the long-term use, make the heat exchanger tube in the heat exchanger generate incrustation scale inevitably,, the thermal efficiency of water heater is reduced and waste energy because the incrustation scale thermal conductivity factor is low, in addition when intermittently using hot water, the initial coolant-temperature gage that flows out is very high, and this can make troubles to the user, even scalds.
The content of utility model:
The purpose of this utility model provides a kind of simple in structure, and is with low cost, can prevent that incrustation scale forms and the hot gas heater antiscale burn-proof device of ponding in the heat exchanger of the flame-out back of gas heater.
The utility model is achieved in that
The utility model is a gas heater antiscale burn-proof device, piston 2 or elastomeric bladder or flexible helix tube are arranged in the water container 1, be divided into the epicoele 3 and the cavity of resorption 4 of this isolation of ripple, epicoele 3 connects with the pipeline 8 of threeway ejector 11 by pipeline 7, the hole 14 of cavity of resorption 4 and pipeline 5 are communicated with, both also connect with the gas heater cold water inlet by pipeline 6, the other end of pipeline 5 connects with running water pipe, the pipeline 9 of threeway ejector 11 connects with gas heater hot water outlet pipe, and the pipeline 10 of threeway ejector 11 connects with outlet pipe.
The pipeline 8,9,10 of threeway ejector 11 communicates with trunnion 12, and the internal diameter of trunnion 12 is less than pipeline 8,9,10 internal diameter.
The pipeline 10 of threeway ejector 11 connects or/and pipeline 5 connects with water intaking valve with hot water effluent's valve.
Pipeline 6 and pipeline 7 have one section wall to be arranged side by side by wall.
Operation principle of the present utility model is as follows:
Set up a water container 1 before the water heater cold water water inlet pipe, the water heater hot-water delivery port is set up a threeway trunnion ejector 11, has piston 2 (or elastomeric bladder or flexible helix tube) that container chamber is separated into epicoele 3 and cavity of resorption 4 in the container 1.Cavity of resorption 4 links to each other with the water heater cold water water inlet by pipeline 6, and epicoele 3 links to each other with the pipeline 8 of threeway trunnion ejector 11 by another pipeline 7, and the pipeline 9 of threeway trunnion ejector 11 links to each other with the water heater delivery port.When opening cold water water intaking valve or hot water effluent's valve, cold water divides two-way, one the tunnel enters water heater heating back flows out by threeway trunnion ejector, another road enters the container cavity of resorption, according to principle of hydrodynamics, will make upper and lower cavity generation pressure reduction in the container, promptly descend cavity pressure greater than epicoele, cause piston stroking upward, water storage is finally all flowed out from the threeway ejector in the epicoele.Close cold water water intaking valve or hot water effluent's valve, piston is because of gravity descend (elastomeric bladder convergent force or flexible helix tube by counterweight 13), the waste heat of taking away heat exchanger by heat exchanger prevents the generation of incrustation scale thereby the water that promotes the container cavity of resorption flows, help energy savings, and can be when intermittently using hot water, avoid making troubles, prevent to scald to the user.

The specific embodiment:
There is piston 2 to be divided into epicoele 3 and cavity of resorption 4 in the water container 1 of the present utility model, epicoele 3 connects with the pipeline 8 of threeway ejector 11 by pipeline 7, cavity of resorption 4 is connected with the gas heater cold water inlet by pipeline 6 with pipeline 5, and the pipeline 9 of threeway ejector 11 is connected with gas heater hot water outlet pipe.The pipeline 10 of threeway ejector is connected with hot water effluent's valve.
Open cold water water intaking valve or hot water effluent's valve, cold water flows out by pipeline 5 → pipeline 6 → water heater heating back → pipeline 9 → ejector trunnion 12 → pipeline 10.Another road cold water enters container cavity of resorption 4 and promotes piston stroking upward, and the water of container epicoele is flowed, and its flow path is container epicoele 3 → pipeline 7 → pipeline 8 → pipeline 10 → hot water effluent valve.Close cold water water intaking valve valve or hot water effluent's valve.Piston is mobile because of gravity decline (contraction of elasticity water pocket, flexible helix tube shrink because of counterweight 13 descends) promotes the interior water of container cavity of resorption, its flow path is: cavity of resorption 4 → pipeline 6 → heat exchanger → pipeline 9 → trunnion 12 → pipeline 8 → pipeline 7 → container epicoele 3, piston drops to the qualification position at last, container upper and lower cavity pressure reaches poised state, thereby has realized the purpose to the heat exchanger cooling.If select the container of suitable volume for use, can make the interior water temperature of pipeline of heat exchanger be controlled at normal temperature, the hot water water temperature control that is back to the container epicoele is below 40 ℃.
