Abstract
The utility model relates to a connecting element for gas (smoke) exhaust tube more particularly suitable for connecting pipeline of gas (smoke) exhaust tool in kitchen and toilet with gas (smoke) exhaust pipe well in room. The technical project of the utility model is achieved by distributing more screws radically on a sheath-type pipe at the part with a larger diameter, wherein the sheath-type pipe is formed by integratedly connecting a pipe with a larger diameter and a pipe with a smaller diameter, and difference of the outer diameters of the two pipes is 2-10 mm. To improve sealing performance of the pipes, a sealing element is arranged at the outer end of the pipe with larger diameter, and another sealing element is arranged to the outer circumference of the connection part of the two pipes. The utility model has the advantages of simple structure, convenient installation and application, good sealing effect, and high exhausting efficiency for gas (smoke).
Description
Technical field
The utility model relates to a kind of air draft (cigarette) tubular union, is specially adapted to being connected of air draft (cigarette) pipeline opening in pipeline and the room of air draft (cigarette) utensil of kitchen, toilet.
Background technique
At present air draft (cigarette) conduit shaft in the pipeline of air draft (cigarette) utensil of kitchen, toilet and the room is connected normally directly grafting use.In the installation process, the degree of depth that the pipeline of air draft (cigarette) utensil is inserted into conduit shaft is difficult to grasp, and crossing influence wind (cigarette) discharging deeply, too shortly causes pipeline to connect to come off, and living to people makes troubles.And pipeline lacks supporting seal approach after connecting, the effect of influence discharging.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and air draft (cigarette) tubular union of a kind of convenience, practicality is provided.
Its technological scheme is: at the above screw that is radially distributed with of the extra heavy pipe path portion of a cannula-like pipe fitting that is connected to form by extra heavy pipe footpath and tubule footpath integral body, the external diameter difference of different diameter is between the 2-10 millimeter.
In order to improve the sealability between the pipe fitting, the external port in the extra heavy pipe footpath is provided with Sealing, is provided with Sealing in the outer periphery of different diameter connecting part.
The utlity model has simple in structurely, install and use all easily, and good airproof performance does not return wind (cigarette), air draft (cigarette) efficient height.
Description of drawings
Accompanying drawing is an a kind of embodiment's of the present utility model structural representation.
Embodiment:
With reference to accompanying drawing, at a cannula-like pipe fitting that is connected to form by extra heavy pipe footpath 2 and tubule footpath 5 integral body, length, the bore of pipe fitting are provided with as required, usually between 80-120 millimeter, 140-200 millimeter.Extra heavy pipe footpath 1 part be radially distributed with an above screw, is connected and fixed by the pipe fitting 3 of bolt 4 (or screw) in the screw air draft (cigarette) utensil.Slightly, the external diameter difference in tubule footpath is between the 2-10 millimeter.In order to improve the sealability between the pipe fitting, the external port in extra heavy pipe footpath 2 is provided with Sealing 1, is provided with Sealing 1 in outer periphery thick, connecting part, tubule footpath.
During use, at first tubule is directly held in the circular hole that is inserted into the conduit shaft reservation, involutory to Sealing and circular hole sealing.Pipe fitting with the air draft utensil is inserted in the extra heavy pipe footpath then, and is fixed in the extra heavy pipe footpath by bolt, and adds the plug Sealing at collar extension.Link can use plastics or PVC materials processing to make, and Sealing can use rubber seal.
Claims (2)
1, a kind of air draft (cigarette) tubular union is characterized in that: at the above screw that is radially distributed with of the extra heavy pipe path portion of a cannula-like pipe fitting that is connected to form by extra heavy pipe footpath and tubule footpath integral body, the external diameter difference of different diameter is between the 2-10 millimeter.
2, air draft according to claim 1 (cigarette) tubular union is characterized in that: the external port in the extra heavy pipe footpath is provided with Sealing, is provided with Sealing in the outer periphery of different diameter connecting part.
