Abstract

The utility model discloses a sealing block used for leading a pipeline to pass through. The sealing block comprises an upper mould block and a lower mould block, wherein a through hole for allowing the pipeline to pass through is formed between the upper and the lower mould block, one or more filled layers are arranged in the through hole, and each filled layer is made of self-adhesive material. The sealing block provided by the utility model can adapt to pipelines with different diameters by increasing or reducing the number of the filled layers, and the application of the self-adhesive material can prevent the filled layers from dropping off, so as to improve the sealing performance of the sealing block. Furthermore, the sealing block is simple in structure, the production of various mould blocks in different specifications is not needed, and the cost is reduced.

Description

Sealing block

Technical field

The utility model relates to technical field of sealing technology, relates in particular to the sealing block that a kind of running line line, pipeline etc. pass.

Background technique

In fields such as building or boats and ships; the capital has a large amount of as electric conduit; cable; wire core; supplying pipe; escape pipe; water pipe; pipelines such as hydraulic tube need run through the wall portion of these structure or dividing plate and be provided with; for sealing that guarantees wall portion or dividing plate perforation place and the pipeline of protecting these to lay; the dealer adopts the elastic cushion block with through hole to be set in outside the pipeline; the cushion block outside then is to be placed in the framework of wall portion or dividing plate; again to hold down assembly with the cushion block pressing; utilize its elastic strain; sealing between the pipeline that keeps wall portion or dividing plate perforation place and pass in it can protect pipeline not to be subjected to fire again; cigarette; the influence of gas or water.

Yet, the pipeline of different-diameter size and dividing plate conditional decision these elastic cushion blocks must make corresponding size, cause its Dimensions various, should not form mass production, the product cost is higher, uses for simultaneously the purchasing of product, storage and execute-in-place and all brings great inconvenience.

How providing a kind of new elastic cushion block to adapt to the pipeline of various diameters, is the technical problem that those skilled in the art need solve.

The model utility content

The purpose of this utility model is in order to solve the defective of above-mentioned prior art, and the sealing block that provides a kind of skirt line to pass.

For achieving the above object, the utility model provides a kind of sealing block that the skirt line passes that is used for, and it comprises upper module and lower module, has the through hole that passes for pipeline up and down between the module, has one or more layers packed layer in the through hole, and described packed layer is a self adhesive material.

Further, described packed layer comprises last packed layer and the following packed layer that matches with module up and down.

Further, described self adhesive material is a self adhesive rubber.

Further, described self adhesive rubber is a kind of of nitrile butadiene rubber, natural concentrated rubber, neoprene, spongy rubber.

Further, described self adhesive rubber is nitrile butadiene rubber.

Further, described module up and down is plastics or rubber.

The utility model is owing to adopt technique scheme, the pipeline that can adapt to the different-diameter size by the number of plies that increases or reduce packed layer, and the application of self adhesive material can be avoided coming off of packed layer, thereby improved the sealability of sealing block, and the utility model is simple in structure, do not need to produce again the module of various different sizes, reduced cost.

Description of drawings

For clearlyer understanding the purpose of this utility model, characteristics and advantage, below with reference to accompanying drawing preferred embodiment of the present utility model is described in detail, wherein:

Fig. 1 is the structural representation of the utility model sealing block.

Embodiment

That Fig. 1 shows is a sealing block embodiment of the present utility model, the profile of the sealing block 2 in the present embodiment is cuboids, can the shape of any adaptation dividing plate in the practical application, sealing block 2 has upper module 21 and lower module 22, has semi-circular through hole up and down between the module, pass to cooperate, have on the several layers of semicircle packed layer 23 under packed layer 24 and the several layers of semicircle in the through hole, form through hole 25 up and down between the packed layer than minor diameter for pipeline.

In the present embodiment, the material of module is plastics up and down, and the material of packed layer is the nitrile butadiene rubber with self adhesive up and down.

In the using process,, stick or peel off the corresponding packed layer number of plies up and down to adapt to according to the actual diameter of pipeline, best is that sealing block 2 internal diameters are more smaller than pipeline external diameter, like this, after outside pipeline, wrapping sealing block 2 of the present utility model and compressing again, can effectively improve sealability.
