Embodiment
Illustrate by Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of seal arrangement of closed hole, mainly by auxiliary seal connection set 1, elastomer seal 2 and hold down gag 3 are formed, wherein: the auxiliary seal connection set 1 that will have Sealing 11 is covered on the hole 12 of needs sealing, and be connected with agent structure 13, its structural type is similar to flange plate, and is provided with mounting hole 14; In mounting hole 14, insert elastomer seal 2, the shape of the mounting hole 14 of its profile and auxiliary seal connection set 1 adapts, it installs the hole sectional area of sectional area greater than auxiliary seal connection set 1 mounting hole 14, on elastomer seal 2, have and pass the corresponding elongated hole 22 of extension piece 21 quantity in hole 12, the diameter in its hole should be slightly smaller than the diameter in extension piece 21 cross sections, and the side in the hole can have side direction as required and crack 23; In mounting hole 14, insert the hold down gag of forming by sealing baffle 31 and hold-down bolt 32 3, have with mounting hole 14 in the upper and lower settings of elastomer seal 2 and to be complementary, and sealing baffle 31 that can be self-align, one is in mounting hole 14, another places the external structure edge of mounting hole 14, and the logical hold-down bolt 32 that is installed with in heart position therein, by hold-down bolt 32 sealing baffles 31 can be mutually near with extruding elastomer seal 2 with obtain the self-align supporting at mounting hole 14 external structure edges; In elastomer seal 2 contact position,, coat adhesive with lubrication at the side direction of elastomer seal 23 positions of cracking with auxiliary seal connection set 1 and extension piece 21.
Know again, the effect of this device is that one or more extension pieces 21 are packed in the elongated hole 22 of elastomer seal 2, elastomer seal 2 is packed in the mounting hole 14 of auxiliary seal connection set 1, two sealing baffles 31 rely on hold down gag 3 extruding force to be provided for elastomer seal 2, in the installation process, the contact position of elastomer seal 2 and auxiliary seal connection set 1 and extension piece 21, the adhesive with lubrication is coated at the side direction of elastomer seal 2 23 positions of cracking, the auxiliary seal connection set 1 general flange of band O type Sealing or pad that adopts connects, or adopt and weld, the mode of being tightly connected of glueing joint connects, and be covered on the hole of sealed main structure, form the sealing in complete hole.
Know again, the structural type of auxiliary seal connection set 1 is a similar flange plate structure, size is greater than the hole that needs on the object to seal, be shaped on the hole that is complementary with elastomer seal 2 on it, pore size is decided by extension piece 21 sectional areas sum total and layout situation, the hole can be the hole, plane, and the elastomer seal 2 and spill sealing baffle 31 couplings that have annular groove with the edge are used; The hole also can be a cone shape hole, uses with taper elastomer seal 2 and plane sealing baffle plate 31 couplings.A kind of like this structural type is that the sealing problem of hole and extension piece 21 is resolved into the sealing in independent hole and the sealing problem of extension piece 21, has disperseed difficult point, simplifies the structure, and gives the seriation of seal arrangement and the condition that feasibility has been created in standardization.
As seen from the figure, sealing baffle 31 with mounting hole 14 matching Design, back two sealing baffles 31 are installed are cooperated the location with mounting hole, the two clamping force of inside and outside sealing baffle 31 is also impelled with mounting hole 14 to cooperate the location to obtain to support except the effect of pressure elasticity Sealing 2 during work.
The mounting hole that is auxiliary seal connection set 1 as another embodiment of the present utility model is through hole type mounting hole 16, adopted the spill sealing baffle 33 of butt joint up and down for this reason, inserts elastomer seal 2 middle parts in the two formed inner chamber and places to compress and use bolt.The raised edges of the spill sealing baffle 33 of butt joint contacts the location and obtains supporting with auxiliary seal connection set 1 bore edges 15 up and down simultaneously, the clamping force that two spill sealing baffles 33 produce during work is except passing through the effect of baffle plate inner chamber pressure elasticity Sealing 2, also can impel the edge clamping stressed joint with the hole, assist the sealing of spill sealing baffle 33 and bore edges 15 simultaneously by the deformation of elastomer seal 2.
Other knows that the utility model is tested structural member shown in Figure 5, and its test situation and result are as follows:
Test another embodiment's of seal arrangement the utility model in hole structure, wherein extension piece is the cable of Φ 18mm, elastomer seal 2 and rubber o-ring adopt the rubber material of shore hardness 20～80, auxiliary seal connection set 1 adopts stainless steel 1Cr18Ni9Ti, and test is with seal arrangement totally 10 covers.
