Abstract
The utility model discloses a special waterproof device of a smoke tube of a gas wall-hang boiler, which is a conical plastic circular tube with the conical degree being 2 degrees to 3 degrees. The inner diameter of the small end of the circular tube is tightly mated with the outer diameter of the smoke tube; a flange disc protruding backwards and provided with a radial gap is arranged on the surface of the small end of the circular tube; and the large diameter of the circular tube is mated with the diameter of a wall hole, and a flange disc tightly adhered with a wall surface is arranged at the large diameter of the circular tube. The special waterproof device thoroughly solves the waterproof problem in the installation of the smoke tube of the gas wall-hang boiler.
Description
Technical field
The utility model relates to burnt gas wall hanging furnace, relates in particular to the installing component of burnt gas wall hanging furnace.
Background technology
Burnt gas wall hanging furnace is the gas-heating water heater again; Mostly the smoke pipe of present known burnt gas wall hanging furnace is coaxial balanced type; Need link with outside atmosphere when mounted, smoke pipe stretches out when outdoor, and porthole and smoke pipe diameter will have the assemblage gap of 3～5mm at least; After the smoke pipe installation, the rainwater meeting flows to indoor along this gap or flows in the exterior-wall heat insulation interlayer.So the smoke pipe waterproof is a urgent problem.
Summary of the invention
The purpose of the utility model is for solving the waterproof problem that the burnt gas wall hanging furnace smoke pipe is installed, a kind of special-purpose water-proof device being provided.
A kind of burnt gas wall hanging furnace smoke pipe special-purpose water-proof device, it is a kind of tapering 2-3 ° a conical plastics pipe; Pipe small end internal diameter and smoke pipe external diameter closely cooperate, and the small end end face is provided with to rearward projection and ring flange that have radial gap; Match with the porthole diameter in the big footpath of pipe, the big footpath of pipe is provided with the ring flange of being close to metope.
In order in the porthole slit, to squeeze into the polyurethane foam encapsulant, the ring flange of pipe small end is provided with circular hole.
The utility model has the advantages that: during installation, outside wall, the small end end face is pushed the porthole inwardly,, fill in and form a kind of hangnail expanded joint structure behind the porthole, prevent that the private seal apparatus from withdrawing from because of the special-purpose water-proof device has the flange disk that cracks.And then from circular hole, squeeze into the polyurethane foam encapsulant and stop up the space, smoke pipe prevents that rainwater from pouring within the body of wall after installing, and has thoroughly solved the waterproof problem that the burnt gas wall hanging furnace smoke pipe is installed.
Description of drawings
Fig. 1 is the structure chart of the utility model.
Among the figure: 1-conical plastics pipe, 2-ring flange, 3-ring flange, 4-circular hole, 5-radial gap.
The specific embodiment
With reference to the accompanying drawings the utility model is further specified.
A kind of burnt gas wall hanging furnace smoke pipe special-purpose water-proof device, it is a kind of tapering 2-3 ° a conical plastics pipe 1; The small end internal diameter and the smoke pipe external diameter of conical plastics pipe 1 closely cooperate, and the small end end face of conical plastics pipe 1 is provided with to rearward projection and ring flange 2 that have radial gap 5; Matching with the porthole diameter in the big footpath of conical plastics pipe 1, and is provided with the ring flange of being close to metope 3.
In order in the porthole slit, to squeeze into the polyurethane foam encapsulant, ring flange 2 is provided with circular hole 4.
