Description
Technical field:
The utility model relates to fireplace chimneys field, particularly relates to a kind of spiral double-layer heat insulation metal smoke evacuation system straight pipe connecter.
Background technology:
Fireplace is a kind of equipment of heating of lighting a fire of leaning on wall to build in indoor.Fireplace is used for western countries originally, has decoration function and practical value.And according to the culture of country variant, be divided into: American fireplace, English fireplace, French fireplace etc., moulding is therefore different.Fireplace basic structure comprises: mantel pick-up and fireplace core.Mantel pick-up plays decoration function.Fireplace core plays practical effect.Mantel pick-up, is categorized as according to material difference: marble hearth frame, wooden mantel pick-up, marble-like fire place frame (resin), pile up mantel pick-up.Fireplace core, based on fuel difference is categorized as: electric fireplace, real flame fireplace (combustion carbon, firebrand), gas firing wall (natural gas).Real flame fireplace will have the support of architectural design, needs chimney, burner hearth.Burner hearth can be cast iron fireplace core, also can be that refractory brick is piled up.Generally Flue duct design is had in western countries.So western countries also generally adopt real flame fireplace.And electric fireplace is installed simple, collocation mantel pick-up by domestic do not have the house type of Flue duct design adopt.Domestic heating system is central heating after all.But it is many to decorate composition after all, and practical value is little.Real flame fireplace is mainly used in villa at home, but the value of heating is also little.Have for barbecue.There is not some local flavor.State's interior trim had also much installed fireplace in recent years.
The installation of usual fireplace will be determined according to house structure itself, and for the fireplace in modern times, generally have two types, a class is the fireplace of steel construction, is generally produced in batches by factory, and another kind of is masonry fireplace, by making by hand.Iron and steel fireplace is at present comparatively general, and it is easy for installation, as long as this fireplace to be directly discharged into the position reserve in room just passable for setter, and this fireplace can not cause the burning of neighbouring object because its appearance is overheated.
Fireplace seems that because being connected with chimney some is mysterious, and chimney is the passage connecting the external world and Inner-world.The Main Function of chimney is the cigarette that puts a chimney on the stove and make the fire draw, and drains flue gas, improves burning condition.Chimney is one of the most ancient, most important environmental control system.This method has remained hundreds of thousands year as a kind of human practice activity of specification.The mankind had once spent long time to improve chimney.And at present, existing brick chimney, because it uses inconvenient, can not meet the needs of modern resident living.And existing metal chimney, effect of heat insulation is poor, and installs and uses also inconvenient.
The connected mode of traditional double-layer heat insulation smoke evacuation system is direct insertion, and namely port adopts concentric reducer grafting, the mode that external application anchor ear is fixing.This connected mode shortcoming be when port due to heat-preservation cotton rainy day or air humidity larger easily absorb water in air part, reduce chimney heat insulation effect, chimney systems deadweight can be increased simultaneously, can potential safety hazard be caused.
Utility model content:
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of easy for installation, spiral double-layer heat insulation metal smoke evacuation system straight pipe connecter that sealing effect is good.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of spiral double-layer heat insulation metal smoke evacuation system straight pipe connecter, it is characterized in that: comprise straight-through connector body, described connector body is made up of internal layer, skin and the heat-preservation cotton be filled between ectonexine, the upper port of described connector body is closed and is welded with convex annular end cap, the lower port of described connector body is closed and is welded with annular recessed end cap, described heat-preservation cotton be closed in internal layer, skin, between convex annular end cap and the recessed end cap of annular, described convex annular end cap is provided with external screw thread, the recessed end cap of described annular is provided with internal thread.
Described internal layer and skin are made up of stainless steel material.
The utility model structure is simple, quick connection can be realized, quick and easy for installation, smoke evacuation system reaches fastening effect by screw thread compact siro spinning technology, reaching thoroughly blocking-up rainwater or steam like this enters in smoke evacuation system heat-preservation cotton, save the mounting materials such as anchor ear simultaneously, make installation effectiveness improve more than 3 times than the smoke evacuation system with anchor ear.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of spiral double-layer heat insulation metal smoke evacuation system straight pipe connecter, comprise connector body, connector body is made up of internal layer 1, skin 4 and the heat-preservation cotton 5 be filled between ectonexine, the upper port of connector body is closed and is welded with convex annular end cap 2, the lower port of connector body is closed and is welded with annular recessed end cap 7, heat-preservation cotton 5 be closed in internal layer 1, outer 4, between convex annular end cap 2 and the recessed end cap 7 of annular, convex annular end cap 2 is provided with external screw thread 3, annular recessed end cap 7 is provided with internal thread 6.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
