Description
Technical field
It the utility model is related to air preheater technical field of sealing technology, and in particular to a kind of for the dismountable of air preheater
Bobbin carriage sealing device.
Background technology
Increasingly serious with Environmental Protection Situation, China's major part boiler emission flue gas all needs to carry out the place of desulfurizing and denitrifying process
Discharged again after reason, after desulphurization denitration equipment is installed additional, the corrosion of back-end surfaces is more acute, and low-temperature zone air preheater is more
Change more frequently, traditional air preheater bobbin carriage tube-to-tube sheet connection uses welded seal form, typically will be whole when changing air preheater
Body air preheater bobbin carriage is all changed, and adds boiler operatiopn and the cost of overhaul.
The content of the invention
It is provided by the utility model a kind of for the detachable of air preheater for the problems of in the prior art
Bobbin carriage sealing device, can not only sealing, and convenient disassembly be fixed to air preheater pipe and air preheater boxboard.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of dismountable bobbin carriage sealing device for air preheater, including air preheater pipe and air preheater boxboard, institute
State air preheater boxboard to be connected with the air preheater pipe provided with hole, the one end in the hole and the mouth of pipe phase of the air preheater pipe
Match somebody with somebody, sealing gasket is provided between the other end in the hole and the air preheater pipe to seal, the sealing gasket is set to ring-type, described close
The internal diameter of packing matches with the air preheater pipe, and the side of the sealing gasket external annular surface slopes inwardly, the sealing gasket side
Wall is provided with opening.
As a kind of perferred technical scheme, the one end in the hole of sealing gasket and the outer shroud phase of the sealing gasket are inserted
Match somebody with somebody.
As a kind of perferred technical scheme, the sealing gasket is set to graphite grazing pad.
As a kind of perferred technical scheme, the gradient of the intilted external annular surface of the sealing gasket is 15 degree -30
Degree.
As a kind of perferred technical scheme, the opening and the angle of the sealing gasket end face are 45 degree.
The beneficial effects of the utility model are shown：
Air preheater pipe and air preheater boxboard are tightly connected by the utility model by sealing gasket, and sealing is good, Neng Gouda
To air preheater seal request, sealing gasket is made of graphite, and processing is simple, can be mass, and manufacturing cost is low so that empty pre-
The disassembly and installation of device pipe and air preheater boxboard is very convenient, avoids when changing air preheater that overall air preheater bobbin carriage is whole
Change, saved cost.

Embodiment
For the ease of it will be appreciated by those skilled in the art that being further described below in conjunction with the accompanying drawings to the utility model.
Fig. 1 is overall structure diagram of the present utility model, including air preheater pipe 2 and air preheater boxboard 1, air preheater boxboard
1 is connected provided with hole with air preheater pipe 2, and the one end in hole and the mouth of pipe of air preheater pipe 2 match, the other end and the air preheater pipe in hole
Sealing gasket 3 is provided between 2 to seal, sealing gasket 3 is set to ring-type, and internal diameter and the air preheater pipe 1 of sealing gasket 3 match, sealing gasket 3
The side of external annular surface slopes inwardly, and the side wall of sealing gasket 3 is provided with opening 4, inserts one end and the sealing gasket 3 in the hole of sealing gasket 3
Outer shroud match.
Fig. 2 be the utility model in sealing ring structural representation, the gradient of 3 intilted external annular surface of sealing gasket
For 15 degree of -30 degree；Opening 4 and the angle of the end face of sealing gasket 3 are 45 degree.
Specific works mode of the present utility model is as follows：
For the utility model by the junction embedding sealing pad 3 in air preheater pipe 2 and air preheater boxboard 1, sealing gasket 3 is stone
Ink material is made, and graphite is soft and high temperature resistant, the seal assembly being highly suitable as between air preheater pipe 2 and air preheater boxboard 1,
The side wall of sealing gasket 3 is provided with opening 4, is easy to sealing gasket 3 being placed on air preheater pipe 2, the one end in the hole on air preheater boxboard 1 with
The outer shroud of sealing gasket 3 matches, so that sealing gasket 3 can be connected between air preheater pipe 2 and air preheater boxboard 1, sealing
The side for padding 3 external annular surfaces slopes inwardly so that the sky that sealing gasket 3 is facilitated access between air preheater pipe 2 and air preheater boxboard 1
Gap, by mutually being clamped between air preheater pipe 2, air preheater boxboard 1 and sealing gasket 3, realize air preheater pipe 2 and air preheater boxboard
1 being fixedly connected and seals.
Above content is only to structure example of the present utility model and explanation, the technology of affiliated the art
