Description

A kind of pipeline damping sealing device

[technical field]

The utility model relates to a kind of pipeline damping sealing devices.

[background technique]

Cable channel sealing in the prior art, all using inflatable seal bag；The application of its inflatable seal bag is wide It is general；In the hole and pipeline that most underground that is laid in, through walls, floor have cable to pass through, a variety of cable tubing mouths electricity can be suitble to The problems such as cable diameter is irregular, cable is not placed in the middle in the duct seals；But it is deposited in this inflatable seal bag material In following disadvantage, the technical issues of probability of gas leakage cannot ensure, cannot prevent fires, protection against rodents；And pipeline opening is generally in outdoor setting, And these places are exactly the more places of other toys such as mouse；And it is once damaged by mouse or other animal bites, it will lead Gas leakage is caused, so that the effect of sealing is not achieved by broken meeting in sealing performance；Filled polyurethane resin not even if in hermetic bag It can play the role of the problem of protection against rodents is wanted, in addition, fire protection flame retarding can not be played, in order to solve the problems in the prior art, this Utility model proposes a kind of with protection against rodents, fire prevention, waterproof, shock-absorbing function seal for pipe joints damper.

[utility model content]

The purpose of this utility model, exactly solve inflatable seal for pipe joints bag in the prior art cannot play simultaneously protection against rodents, Fire prevention, waterproof and the problem of apply the cable damping in bridge anchorage；And the problem of antidetonation shock attenuation can also be played.

In order to achieve the above object, the utility model patent proposes a kind of pipeline damping sealing device, and feature includes close Envelope and filler, the envelope are equipped with a filler and are placed in mouth, and the hermetic bag is divided into internal layer, outer layer and centre Layer, the middle layer are the stainless (steel) wire with protection against rodents, fire-proof function, the internal layer and outer layer be PE layers, PA layers, layer of PVC, One of MPP layers or a variety of of combination；The filler is that acrylates and water are mixed with elasticity and non-ignitable function The solid gel with elasticity and fire-proof function that the silica gel or oryolite and water of energy mix；The filler fills up Entire hermetic bag；The both ends of the stainless (steel) wire are welded to each other connection between the inner layer and the outer layer.

The utility model patent can play the role of protection against rodents, fireproof simultaneously, and apply and can rise on bridge rope To the effect of damping, to ensure the sealing performance at pipeline opening, to prevent mouse hermetic bag of breaking by the teeth from entering in pipeline and break The technical issues of meeting pipeline and cable.

The sealer solves the problems, such as mouse bite preventing by using stainless (steel) wire；It can solve not using filling gel material The problem of combustion；Wrapping up stainless (steel) wire with internal layer by outer layer is to solve the problem of aging of silica gel in bag body and prevent acrylates from meeting The problem of water reaction can be leaked at the initial stage of solid-state silica gel and bag body heat-sealing bonding molding needs；In addition inside and outer layer do not have Fire-proof function, when bag body outer layer first and inside burning are corroded in high fire, at this time silica gel is because be solid still by stainless steel Net package, to will not leak；And silica gel and stainless (steel) wire are impossible to be burned, to reach fire-proof function；And silicon The high resiliency that elasticity, flexibility and the stainless steel mesh bag that glue or solid gel have tightly wrap up, can reach waterproof and reach It is very reasonable to shock-absorbing function；And because filler silica gel or solid gel in the sealer have certain elasticity And flexibility, so apply on the cable in bridge anchorage, so as to collide in strong wind or vehicle and bridge or bridge When being vibrated on beam due to extraneous factor, to reach the function of damping, buffering.

[Detailed description of the invention]

Fig. 1 is the planar structure schematic diagram of the utility model hermetic bag；

Fig. 2 is the hierarchical structure schematic diagram of the utility model hermetic bag；

Fig. 3 is that the utility model uses partial profile structure；

It is identified in figure: 1 hermetic bag, 2 fillers, 3 fillers merging mouth, 4 stainless (steel) wires.

Specific embodiment

Embodiment 1:

Refering to fig. 1 to 3, the utility model patent proposes the seal for pipe joints bag of a kind of protection against rodents, fire-type, and feature includes Hermetic bag 1 and filler 2, the envelope ontology are equipped with a filler and are placed in mouth 3, and the hermetic bag is divided into internal layer 101, outer layer 102 and middle layer 103, the middle layer 103 are the stainless (steel) wire 4 with protection against rodents, fire-proof function, the internal layer 101 and outer layer 102 be PE layers, PA layers, layer of PVC, one of MPP layers or a variety of combinations；The filler is acrylic acid Salt and water, which mix silica gel with elasticity and non-ignitable function or oryolite, and water mixes has elastic and prevents fires The solid gel of function；The filler fills up entire hermetic bag；

There are two types of the application methods of the utility model；First method is: injecting water into two buckets of A, B, then by third Olefin(e) acid salt is added in two buckets of A, B；Then, 2 feed pipes connected on 2 feed inlets of syringe pump are put into two water of A, B In bucket；Hermetic bag is wrapped on cable in cable again and is put into pipeline；Discharge nozzle connects the filler in close upper envelope and sets later Enter on mouth；Starting two feed pipes of syringe pump are fed simultaneously, after mixing in discharge nozzle, are injected by filler merging mouth close In envelope, hermetic bag is made to start to expand, until hermetic bag expand completely fill up entire pipeline opening and with the connection gap of cable with And hermetic bag is due to package cable and at the fold that generates；Second method is: being wrapped on cable in hermetic bag and is placed in pipeline It is interior, it is preinstalled with oryolite in bag body, water is injected into hermetic bag by injector, hermetic bag is due to hydraulic pressure after water injection Effect slowly expands；Meanwhile the injection of water makes the oryolite water-swellable in hermetic bag, oryolite was mixed with water by a few minutes Oryolite expansion reaction gelled state afterwards, thus make hermetic bag it is swollen fill up entire pipeline opening and with the connection gap of cable and At the fold that hermetic bag is generated due to package winding.

The utility model has the beneficial effects that can prevent mouse from breaking by the teeth by using with protection against rodents, fireproof stainless (steel) wire Directly internal layer is broken by the teeth after the outer layer of hermetic bag, and also enhances the toughness of hermetic bag；And stainless (steel) wire itself is that have resistance Fireproof effect is fired, even being all burned off inside and outside hermetic bag, since stainless (steel) wire mesh number is very small, so having branch Support silica gel or the crystalline solid block with elasticity and fire-proof function, and silica gel and the crystalline solid with elasticity and fire-proof function Not so block is burnt, therefore further function as fire-retardant effect；And then valuable attack time is won for fire fighter；By using The problem of crystalline solid block of silica gel and fire-proof function is broken by the teeth back leak gas so as to avoid hermetic bag and sealing effect is caused to disappear. Due to not having to the problem of worrying gas leakage in hermetic bag, the filler merging mouth is filled mouth using common material, is not necessarily to Select that there is the material of silica gel or gel to fill mouth, to save the construction time；Because silica gel and solid gel are due to meeting water Hermetic bag can be filled automatically and fill up closure at mouth by expansion.

Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, and any pair of sheet is practical new Scheme after type simple transformation belongs to the protection scope of the utility model.
