The utility model discloses a kind of gas-heating water heater outlet flue joint, it is the single piece of exhaust with interior pipe of air inlet outer tube and inside thereof, one end of interior pipe is positioned at outer tube, the other end stretches out outer tube, it is characterized in that: the central shaft of described interior pipe is positioned at the top of the central shaft of outer tube.
The longitudinal section of described interior pipe is the right-angled trapezium of inverted right-angle side in the inner, has horizontal protective plate to be divided into little right-angled trapezium section and rectangular section in right-angled trapezium.
Described outer tube is the overall pipe fitting of positioning section and air inlet section, and the internal diameter of positioning section is greater than the internal diameter of air inlet section; The inwall of positioning section there is the location structure matched with the condenser pipe of gas-heating water heater, be positioned in air inlet section on tube wall following bottom pipe and offer some air admission holes arranged vertically, in order to ensure the patency of air inlet, it is 2:1 that air admission hole area summation and interior tube section amass approximation ratio.
The outer face of described air inlet section to comprise corresponding to interior pipe and interior pipe with the ellipsoid of upper part and interior pipe with the arch surface of lower part, air inlet section and described rectangular section are connected as a single entity by shrouding, the outer wall of rectangular section is evenly equipped with reinforcement along its circumferencial direction, and the outermost end of reinforcement is connected on shrouding.
Described protective plate is the plectane offering some scallop holes, can prevent foreign matter from entering.
Described air admission hole is trapezoidal slotted eye, and one is arranged in the lowermost end of described outer tube, and other trapezoidal slotted eye is symmetrically arranged in the both sides of the trapezoidal slotted eye of lowermost end; The trapezoidal slotted eye that dovetail groove hole width is all equal, length is successively decreased successively from middle past both sides.
Described location structure is the convex projection to inner chamber.
The arch surface of described shrouding and air inlet section is positioned at same plane, closes the region between air inlet section and interior pipe.
Air inlet outer tube of the present utility model and the interior pipe disalignment of exhaust, the central shaft of interior pipe is positioned at the top of the central shaft of outer tube, and the air admission hole of outer tube is opened in bottom it, also can prevent rainwater from flowing in outer tube while making condensate return, the air admission hole of outer pipe bottom can effectively discharge the rainwater entered in outer tube, ensure that the stability that gas-heating water heater runs; It is protruding that outer tube is provided with the location matched with condensation smoke pipe upper groove, ensures that the utility model is installed accurate, stop the potential safety hazard that setup error causes, be also convenient to dismounting.
