Description
Technical field
The utility model is related to sealing device technical field, is related specifically to a kind of sealing device of new structure.
Background technology
Sealing device is to be mainly used in have in the equipment of related request container pressure, and vacuum crawler continuous drier is
In whole dry run, it is desirable to which product is in vacuum, the environment of closing.And the environment of pure closing can prevent air pair
The secondary pollution of product, and when being dried in the case of low pressure, oxygen content is very low, can be effectively prevented and is dried
Material oxidation deterioration, be adapted to natural plants extraction, the particularly drying of Chinese medicine class product.
And the sealing device for being used for vacuum crawler continuous drier is arranged between end door and cylinder, for improve end door with
Sealing property between cylinder, and the overwhelming majority is face sealing between existing sealing device and end door, sealing property is poor, difficult
So that equipment runs well；Another, when end door is separated with cylinder, sealing device is easily from cylinder for existing sealing device
Come off, to the work that is dried of Chinese medicine class product larger difficulty is brought.
But for the deficiencies in the prior art, developer is necessary to develop a kind of reasonable in design, simple structure, sealing property
When good, end door flange is separated with shell flange, the new structure that can effectively prevent sealing device from coming off from shell flange
Sealing device.
Utility model content
To solve the problems, such as prior art, the utility model purpose provides a kind of reasonable in design, simple structure, close
When sealing property is good, end door flange is separated with shell flange, can effectively prevent that sealing device from coming off from shell flange is new
The sealing device of type structure.
To solve above technical problem, the utility model employs the following technical solutions to realize：
A kind of sealing device of new structure, the sealing device is arranged between end door flange and shell flange, its feature
It is that the sealing device includes seal body, and the seal body is outer narrow inner width by the cross section for being connected to shell flange
The first sealing in trapezoidal draw-in groove and the second sealing composition being crimped on end door flange, first sealing and the
Two sealings are integrally formed to form seal body.
In a preferred embodiment of the present utility model, the cross section of first sealing be it is trapezoidal, described second
The cross section of sealing is semicircle.
In a preferred embodiment of the present utility model, the seal body is made using silica gel material.
Compared with prior art, the utility model is provided with the second sealing being crimped on end door flange, and second seals
The cross section in portion is semicircle, and it is linear sealing to enter to exercise between end door flange and the second sealing, and this kind of structure is prevented from end
Outlet gas leak phenomenon between door flange and the second sealing, effectively raises the sealing property of the sealing device；Another, it is horizontal
Section is that the first trapezoidal sealing is connected in the trapezoidal draw-in groove that the cross section of shell flange is outer narrow inner width, can be effective
Sealing device when preventing end door flange from separating with shell flange come off from shell flange, effectively raise the sealing device
Stability between shell flange.
Description of the drawings
In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is the structural representation before the utility model is assembled with end door flange and shell flange.
Fig. 2 is the structural representation after the utility model is assembled with end door flange and shell flange.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Shown in seeing figures.1.and.2, a kind of sealing device of the new structure be given in figure, the sealing device is arranged on end
Between door flange 300 and shell flange 200, the sealing device includes seal body 100.
Seal body 100 by the cross section for being connected to shell flange 200 be in the trapezoidal draw-in groove 210 of outer narrow inner width
One sealing 110 and the second sealing 120 being crimped on end door flange 300 are constituted, the first sealing 110 and the second sealing
120 are integrally formed to form seal body 100.
The cross section of the first sealing 110 is trapezoidal, and the first sealing 110 is connected to the cross section of shell flange 200 and is
In the trapezoidal draw-in groove 210 of outer narrow inner width, sealing dress when can effectively prevent end door flange 200 from separating with shell flange 300
Put from shell flange 200 and come off, effectively raise the stability between the sealing device and shell flange.
The cross section of the second sealing 120 is semicircle, enters to exercise between the sealing 120 of end door flange 300 and second and is
Linear sealing, this kind of structure is prevented from outlet gas leak phenomenon between the sealing 120 of end door flange 300 and second, effectively improves
The sealing property of the sealing device.
Seal body 100 is made using silica gel material, the good seal performance of silica gel material, and high temperature resistant weatherability is anti-aging
Anti-fight, shockproof waterproof, surfacing, expansion density are uniform, all kinds of smooth surface materials that can fit and good top layer is not glued
Property, permeability is good, and then effectively raises the Practical Performance of the sealing device.
In sum the utility model is provided with the second sealing being crimped on end door flange, and the second sealing is transversal
Face is semicircle, enters to exercise between end door flange and the second sealing for linear sealing, this kind of structure be prevented from end door flange with
Outlet gas leak phenomenon between second sealing, effectively raises the sealing property of the sealing device；Another, cross section is ladder
First sealing of shape is connected in the trapezoidal draw-in groove that the cross section of shell flange is outer narrow inner width, being capable of effective anti-not-go-end
Sealing device comes off from shell flange when door flange is separated with shell flange, effectively raises the sealing device and cylinder method
Stability between orchid.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
