Abstract
The utility model discloses a sealing device with holes and relates to the field of sealing, in particular to the sealing device which is applicable to sealing between spaces with different air pressures. The device consists of a sealing part, a sealing groove and a groove cover, wherein the groove cover limits the sealing part in the sealing groove, the sealing part is an inflatable hollow structure, and an air balance air hole is arranged at one side; and the space formed by the groove cover and the sealing groove is matched with the shape of the sealing part, when the sealing part is placed in the sealing groove, the air hole of the sealing part faces to one end of the space with high air pressure, and an air hole which corresponds to the air balance air hole is arranged on the surface which faces to the space with the high air pressure of the sealing groove. The sealing device adopts the hollow structure with the holes, makes full use of the air pressure difference between the spaces, and leads the end with the high air pressure to inject air into the hollow structure of the sealing part, thereby leading the surface of the sealing part to be tightly bonded with the surface of the groove cover; and compared with the prior art, the structure is simple, the use is convenient and the sealing effect is better.
Description
Technical field
The utility model relates to field of sealing technology, is specifically related to a kind of sealing configuration that contains Sealing, is applicable to the sealing between the different space of air pressure.
Background technique
At present, the sealing of the gas between space sponge commonly used or various solid Sealing are packed into behind the seal groove, the outside reinforcing of other object compresses Sealing, make Sealing be close to sealing part, thereby gas is plugged and can't circulates between the space, and this sealing means directly causes the quality of sealing effect according to the outside afterburning size of other object.When especially sealing for the pressure change that has pressure difference or space between the space, existing seal arrangement needs constantly to adjust the pressure to Sealing, just might guarantee the technical requirements that seals, the difficult pressure size of grasping Sealing, the sealing means structure more complicated of prior art.
The model utility content
For solving the problems of the technologies described above, the invention provides a kind of simple in structurely, easy to use, can solve the sealing problem that exists between the pressure difference time space, improved device can also solve the draught head variation issue between the space.
A kind of seal arrangement with holes comprises Sealing, sealed groove and recess cover composition, and recess cover is limited in Sealing in the sealed groove, it is characterized in that: described Sealing is inflatable hollow-core construction, and a side has the air balance pore; Formed space of recess cover and sealed groove and Sealing shape are complementary, when Sealing is put into sealed groove, the pore of Sealing simultaneously has and the corresponding pore of air balance pore towards the highpressure space on the sealed groove towards an end in highpressure space.
As improvement structure of the present utility model, can have sealed groove in the different spaces at the place of being tightly connected and put into hollow sealing element with holes, the aperture of Sealing is all towards this space.No matter how gas atmosphere changes, and the Sealing in highpressure space can make the effect that reaches sealing between the space at least.
The utility model adopts porose hollow-core construction, make full use of the draught head between the space, thereby highpressure one end fits tightly the surface of Sealing and the surface of recess cover to the hollow injection air of Sealing, and is compared with prior art simple in structure, easy to use and sealing effect is better.
Description of drawings:
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the working principle schematic representation of seal arrangement with holes;
Among the figure: 1. lowpressure space, 2. Sealing, 3. sealed groove, 4. Sealing pore, 5. highpressure pore, 6. highpressure space, 7. recess cover.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of seal arrangement with holes comprises Sealing 2, sealed groove 3 and recess cover 7 compositions, and recess cover 7 is limited in Sealing 2 in the sealed groove 3, it is characterized in that: described Sealing 2 is inflatable hollow-core construction, and a side has the air balance pore; Recess cover 7 is complementary with sealed groove 3 formed spaces and Sealing 2 shapes, when Sealing 2 is put into sealed groove 3, the pore of Sealing 2 is towards an end in highpressure space 6, and 6 one sides have and the corresponding pore of air balance pore towards the highpressure space on the sealed groove 3.
As improvement structure of the present utility model, can have sealed groove 3 and put into hollow sealing element with holes 2 in the different spaces of needs sealing, the aperture of Sealing 2 is all towards this space.Improved device is applicable to the situation that the air pressure between the gas space changes, when a certain space is relative lowpressure space, the Sealing of its space sealing groove is inoperative, the Sealing in another space by the gas inflated in its space after sealing between the implementation space, when the air pressure in space when to change atmospheric pressure value above another space from low to high be relative highpressure space, the Sealing of its space sealing groove works, and the Sealing in another space is inoperative, has reached the effect of sealing equally.
As preferred version of the present invention, the cross section that Sealing 2 reaches the sealed groove 3 that is complementary with it is preferably rectangle.
Pore on the Sealing 2 in the utility model can be for a plurality of.
As improvement of the present invention, can also be on recess cover 7 be provided with boss towards a side of Sealing 2.The boss squeeze sealing member.Even under the very little situation of the pressure reduction between the space, also can reach the better seal effect.
Boss on the further improved recess cover is a plurality of.
Seal form of the present utility model mainly is to realize sealing by compressing of associated components, a certain space adds and presses to relative highpressure space 6, corresponding pore gives Sealing 2 inflations on air balance pore 4 by Sealing and the sealed groove, make the Sealing periphery adjacent with it sealing surface of under the effect of inner highpressure gas, fitting, thereby reach the better seal effect.
