Background technology
In recent years, the deposit of petroleum-based energy increasingly shows its very important status in the social construction of China, I
State has newly built large quantities of national petroleum reserve base, has built up substantial amounts of petroleum storage tank.Along with safe and environment-friendly requirement
Raising, tank wall of oil tank and floating roof between gap be both needed to install sealing device.
Current domestic internal floating roof tank seal form mainly have tongue shape seal and lamellar sponge bellows seal, along with safety,
The raising of environmental requirement, tongue shape seals and is progressively eliminated, and lamellar sponge bellows is sealed to main flow.But existing lamellar sponge capsule
The sealing property that formula seals still needs further to be improved.
Utility model content
This utility model provides a kind of comb teeth shape for covered floating roof tank to seal, and belongs to lamellar sponge bellows and seals, its
Sealing property has had the lifting of highly significant, thus reduce further oil loss, decreases the peace that oil and gas leakage is brought
Complete and environmental problem.
For solving above-mentioned technical problem, the technical scheme that this utility model is used is as follows:
A kind of comb teeth shape for covered floating roof tank seals, including the first polyurethane sponge layer, the second polyurethane sponge layer
With rubber teeth belt；The longitudinal section of the first polyurethane sponge layer is ring-type, and the second polyurethane sponge layer is wrapped in the first polyurethane
The periphery of spongy layer, rubber teeth belt is wrapped in the periphery of the second polyurethane sponge layer；Have on the outer surface of rubber cingulum mutually
Parallel Elastic Teeth.
The one side of rubber cingulum and the contact of the second polyurethane sponge layer is inner surface, and another side is outer surface, i.e. from first
Polyurethane sponge layer is consistent with direction from inside to outside to the direction of rubber teeth belt.
During use, one end that the comb teeth shape for covered floating roof tank seals is by pressing plate and securing member and inner floating roof edges of boards edge
Connecting, the other end that the comb teeth shape for covered floating roof tank seals is affixed with oil tank wall, particularly for covered floating roof tank
One end of comb teeth shape sealed thin is connected with inner floating roof edges of boards edge, thick and one end is affixed with oil tank wall.
Above-mentioned employing rubber cingulum substitutes rubber flat rubber belting, makes sealing effectiveness be significantly improved, and reduces oil product and damages
Consumption, decreases pollution.
The application makes sealing effectiveness have the lifting of highly significant by the design of rubber cingulum, reduce further oil product
Loss, decreases safety and environmental problem that oil and gas leakage is brought.
In order to improve sealing property further, Elastic Teeth is parallel to each other with the cross section of covered floating roof tank.
In order to further improve sealing property, Elastic Teeth is rectangular teeth.
In order to further improve sealing property, it is preferable that the tooth depth of rectangular teeth is 1.2-1.8mm；The facewidth is 390-
410mm.Further preferably, the tooth depth of rectangular teeth is 1.5mm；The facewidth is 400mm.
In order to further improve sealing property, it is preferable that space width is 2-3mm.Further preferably, space width is 2.5mm.
The application space width refers to the beeline between adjacent two Elastic Teeth heels.
In order to further improve sealing property, it is preferable that the longitudinal section of the first polyurethane sponge layer is that triangle is ring-type.
The NM technology of this utility model is all with reference to prior art.
This utility model makes sealing effectiveness have for the comb teeth shape sealing of covered floating roof tank by the design of rubber cingulum
The lifting of highly significant, reduce further oil loss, decreases safety and environmental problem that oil and gas leakage is brought.

Detailed description of the invention
In order to be more fully understood that this utility model, it is further elucidated with content of the present utility model below in conjunction with embodiment, but
Content of the present utility model is not limited solely to the following examples.
Embodiment 1
As it can be seen, the comb teeth shape for covered floating roof tank seals, including the first polyurethane sponge layer, the second polyurethane sea
Continuous layer and rubber teeth belt；The longitudinal section of the first polyurethane sponge layer is that triangle is ring-type, and the second polyurethane sponge layer is wrapped in
The periphery of one polyurethane sponge layer, rubber teeth belt is wrapped in the periphery of the second polyurethane sponge layer；The outer surface of rubber cingulum
On have the Elastic Teeth being parallel to each other；Elastic Teeth is parallel to each other with the cross section of covered floating roof tank；Elastic Teeth is rectangular teeth；Rectangular teeth
Tooth depth be 1.5mm；The facewidth is 400mm；Space width is 2.5mm.During use, for the comb teeth shape sealed thin of covered floating roof tank
One end is connected with inner floating roof edges of boards edge by pressing plate and securing member, and thick one end is affixed with oil tank wall.
Rubber cingulum sealing effectiveness is more preferable: such as accompanying drawing 1, shown in 3, rubber flat rubber belting is that face contacts with tank skin contact position, and rubber
Glue cingulum is that plurality of parallel lines contacts with tank skin contact position.Because rubber flat rubber belting uses canvas filler rubber to make, its elastic (compressibility)
Fine, in addition face contact, run into tank skin concavo-convex more apparent time arise that gap, cause poorly sealed reality；And rubber
The tooth bit position of cingulum uses pure rubber calendering molding, has good elasticity (compressibility), is again linear contact lay, each parallel lines
The most standby, run into that tank skin is concavo-convex can be mutually compensated for, reach good sealing effectiveness.
Rubber cingulum can reduce pollution: rubber cingulum has good frizing effect with the teeth portion of tank skin contact surface, works as tank
When wall has solidifying oil, solidifying oil is struck off by this tooth potential energy easily, and reflux accumulator, can keep the cleaning of tank skin, can reduce again
The volatilizing loss of the solidifying oil of tank skin and the safety brought and environmental problem.
Rubber cingulum can reduce oil loss: as shown in Figure 4, and gap once and occurs in rubber flat rubber belting between tank skin, just
Oil product leakage rate from this gap can be accelerated, because during oil gas volatilization, the pressure in exit is internal, the most just less than sealing
Define miniature ejector pump, constantly internal toward extraneous oil pumping gas from sealing.Even and if there is seam between rubber cingulum and tank skin
Gap, because it is linear contact lay with contacting of tank skin, oil gas is often crossed a diatom and all can necessarily be spread, and reduces pressure, the most not
Miniature ejector pump can be formed, moreover it is possible to reduce the speed of oil and gas leakage, see Fig. 2.
