Or strip sheet etc., to adapt to different sealing occasion demands.
In the present embodiment, the surface area of adhesive linkage 130 is smaller than the surface of layer 120 in sealing contact, and adhesive linkage
130 periphery will be located within the periphery of layer 120 in sealing contact.It please join Fig. 1, Fig. 2 and Fig. 3, in different specific embodiments,
The periphery of adhesive linkage 130 can be with seal the periphery of bottom 110 flush or positioned at sealing bottom 110 periphery it
It is interior so that at least part layer 120 in sealing contact and sealing bottom 110 between formed with gap；And seal the periphery of bottom 110
Can be positioned at sealing adhesive linkage 130 periphery outside, within or flush, as long as ensure be tightly connected layer 120 joint face
122 positioned at layer 120 in sealing contact periphery and adhesive linkage 130 periphery between parts expose to sealing bottom 110 and/or with
Gap is formed between sealing bottom 110, is so formed between the joint face 122 and contact surface 124 of sealed connection layer 120
During pressure differential, it is to be sealed can at least to ensure that the part for being tightly connected the close periphery of layer 120 can fit tightly on completely
Position, ensure the stability of sealing property.
As shown in figure 1, when the periphery of layer 120 in sealing contact flushes with sealing the periphery of bottom 110, it is preferred that bonding

Structure 100 is fitted in the position to be sealed for the structure for needing to seal with its contact surface 124, and gap is sealed completely, is sealing
The both sides of contact layer 120 form pressure differential, and the pressure of the side of joint face 122 is more than the pressure of the side of contact surface 124.
The larger sealing bottom 110 of rigidity is required to cover the gap at position to be sealed completely, to be formed in sealing paste
After conjunction, effective support is formed, prevents layer 120 in sealing contact to be inhaled into gap.
Above-mentioned position to be sealed is the structure position of relative motion or the structure position of geo-stationary, with corresponding dynamic close respectively
Seal use occasion and static seal use occasion.
Above-mentioned pressure difference sealing structure 100 and using the pressure difference sealing structure 100 pressure difference encapsulating method can either be used for it is quiet
Sealing, and can are enough in dynamic sealing, and especially suitable both sides have the sealing of pressure differential, as used in the vacuum structure with negative pressure
On, wherein layer in sealing contact 120 can directly be fitted in position to be sealed, because layer 120 in sealing contact is elastomer, sealing
In the presence of there is pressure differential the both sides of contact layer 120, position to be sealed can be fitted tightly on, and seals the firm of bottom 110
Spend larger, layer 120 in sealing contact can be given to provide a good pressure and its strength support guarantee, prevent layer 120 in sealing contact
It is inhaled into the presence of pressure at both sides difference in the gap at position to be sealed.
Above-mentioned pressure difference sealing structure 100 and the pressure difference encapsulating method good sealing effect using the pressure difference sealing structure 100, make
With flexible, it is particularly suitable for having sealing problem in the presence of pressure difference, and pressure difference is bigger, effect is better, and when there is pressure difference, has
Effect solves the problems, such as that layer 120 in sealing contact is easily inhaled sealing seam.
