A kind of lower end hermetically-sealed construction of double-layer heat insulation fireplace chimneys
Technical field
The utility model relates to fireplace chimneys field, particularly relates to a kind of lower end hermetically-sealed construction of double-layer heat insulation fireplace chimneys.
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, for the ease of installing and arranging pipeline rout, all adopt segmented to be mutually concatenated use, but existing fireplace chimneys is when connecting, all in work progress, two ends fireplace chimneys is connected and sealed, fireplace chimneys itself does not design hermetically-sealed construction, occur sealing underproof problem through often after having constructed, when fireplace uses, flue gas and wood tar can leak to outside in chimney, and the air of outside also can enter chimney inside, produce condensed water in chimney inside, cause chimney internal corrosion, service life comparatively shortens.
Utility model content
The purpose of this utility model is the lower end hermetically-sealed construction providing a kind of double-layer heat insulation fireplace chimneys, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of lower end hermetically-sealed construction of double-layer heat insulation fireplace chimneys, it is characterized in that: the shell comprising fireplace chimneys and the inner bag be placed in shell, shell is coaxial with inner bag, fill insulant material in interlayer between described shell and inner bag, the upper end of described interlayer is closed by upper end cover, the lower end of described interlayer is closed by bottom end cover, and described inner bag lower end outside offers lower seal groove, is provided with lower seal in lower seal groove.
Described lower seal is made up of high-temperature resistant rubber material, and the cross section of described lower seal is rectangle, offers diamond groove outside cross section.
Described upper end cover and inner bag upper end form the Plug Division of fireplace chimneys, and described bottom end cover and inner bag lower end form the carrier of fireplace chimneys, and during installation, the Plug Division of two sections of fireplace chimneys coordinates with carrier.
Plug Division is inserted in carrier, and the outer wall of Plug Division contacts with lower seal and realizes sealing.
The outer wall of described Plug Division and the inwall of carrier are provided with the threaded joints matched.
Offer sealed groove outside described inner bag upper end, in upper sealed groove, sealing ring is installed; Described upper sealing ring is made up of high-temperature resistant rubber material, and the cross section of described upper sealing ring is circular.
The beneficial effects of the utility model are:
Double-layer heat insulation fireplace chimneys of the present utility model is designed with hermetically-sealed construction, fireplace chimneys does not need to carry out seal construction separately when installing, fit on can realize being tightly connected, can stop flue gas in chimney, leak to outflow that is outside and wood tar during use, play heat preservation and energy conservation effects, stop outside air to enter chimney inside simultaneously, avoid the generation of condensed water to the corrosion of chimney inside.
