Abstract
The utility model relates to an improved central exhaust pipe for a residential housing, comprising a straight pipe. The utility model is characterized in that an angle pipe provided with an upward opening is installed in the straight pipe, and the angle pipe is connected into integration with the straight pipe through a flange; an air inlet is arranged on the lower end of the angle pipe, and a non-return valve which is composed of a frame, a movable cover and connecting pieces is installed in an air outlet arranged on the upper end of the angle pipe. The utility model has the advantages of novel design, simple structure, low manufacture cost, small exhaust resistance and favorable non-return effect; the utility model is a promising product which can replace an existing central exhaust pipe and an existing non-return valve.
Description
The utility model relates to a kind of improved housing construction and concentrates stack.
Housing construction concentrates exhaust system generally to be made up of range hood, check (non-return) valve, concentrated stack, roof air outlet four parts.Establish lower guide plate in the existing concentrated stack, complex structure, and need configuration check (non-return) valve, result to cause that exhaust resistance is big, manufacturing cost is high.
The purpose of this utility model provides a kind of improved housing construction simple in structure, that have non-return function concurrently and concentrates stack.
Task of the present utility model is to realize like this, at first simplify existing concentrated exhaust pipe structure, lower guide plate in the removal changes into bend pipe is set in straight tube, bend pipe lower end air inlet port is connected with the stack of range hood, and its gas outlet, upper end is provided with the check (non-return) valve of being made up of framework, removable cover.
The utility model is novel, simple in structure, low cost of manufacture, and exhaust resistance is little, and is non-return effective, is expected to substitute existing concentrated stack and check (non-return) valve.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
The utility model comprises straight tube 1, it is characterized in that: the bend pipe 2 that opening makes progress is housed in straight tube 1, and bend pipe 2 fuses with straight tube 1 mat flange 3, and there is air inlet port 4 bend pipe 2 lower ends, and the check (non-return) valve of being made up of framework 5, removable cover 6, connector 7 is equipped with in the gas outlet, upper end.Removable cover can be plate shaped, also can be pyramid type, and the vertex of a cone has connector between removable cover and the framework up or down, can be slide bar, and slide bar can slide up and down in the sliding sleeve of framework, also can be chain cable.During exhaust, the stressed rising of removable cover can be discharged waste gas smoothly from the bend pipe gas outlet.When stopping exhaust, removable cover falls because of self gravitation, and natural drowning bend pipe gas outlet can prevent that waste gas from pouring in down a chimney.
Straight tube of the present utility model is a thin-wall member, the composite construction that often adopts cement mortar, fiberglass gridding cloth to strengthen.Check (non-return) valve is a hardware.Bend pipe can be the composite construction the same with straight tube, also can be hardware.
