Especially condensation gas boiler, if test running boiler when the water level in the condensed water receiving tube does not reach a certain height, though then the most waste gas of burning generation can drain into the external world by exhaust outlet, some waste gas can flow into indoor by the condensed water receiving tube.This is the problem that exists in the structure of existing condensation gas boiler.
Task of the present utility model provides the waste gas choke apparatus of a kind of gas fired-boiler with the condensed water receiving tube, in boiler start of run or the operation process, when the water in the condensed water receiving tube of syphon structure does not reach certain water level, can prevent that also the part of waste gas from flowing into indoor by the condensed water receiving tube.
For realizing above-mentioned task, solution of the present utility model is: in the gas fired-boiler with condensation function, the high-temp waste gas that is discharged outside to is undertaken being condensed into liquid after the heat exchange by above-mentioned main heat exchanger, the condensation latent heat that produces when making full use of condensation improves the thermal efficiency of boiler, and the condensed water receiving tube by syphon structure, it is indoor to prevent that waste gas from flowing into.Be provided with the datum level film in the centre of condensed water receiving tube, its middle part is bent downwardly, central authorities are provided with the condensing drip hole of running through the datum level film, and the condensed water ball sealer of big buoyancy is set above it, with the residual water level of benchmark is the center, by condensed water and condensed water ball sealer sealing condensing drip hole, prevent that waste gas from going into indoor by the condensing drip orifice flow of condensed water receiving tube.
Because the gas fired-boiler waste gas choke apparatus of condensed water receiving tube in the utility model, having adopted with the residual water level of benchmark is the datum level film that has the condensing drip hole at center and the design of condensed water ball sealer, make when fully absorbing the condensation latent heat of the high-temp waste gas that produces in boiler initial operation and the operation process, water in the condensed water receiving tube of syphon structure does not reach under the situation of certain water level, make the datum level membrane closure with the condensed water ball sealer, a part that prevents waste gas flows into condensed water receiving tube inside, and reaches indoor.In addition, because the utility model need not use electric control signal, with the automatic choked flow of power of floating, thus the security that has improved boiler greatly, and provide cost savings.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Fig. 1 adopts the cut-away view of the utility model gas fired-boiler with the gas fired-boiler of condensed water receiving tube waste gas choke apparatus.
