Description

But the fire-resistant sealing through-going device of the pipeline of secondary shutoff

Technical field

The utility model relates to fire-resistant seal arrangement, but is specifically related to a kind of fire-resistant sealing through-going device of pipeline of secondary shutoff.

Background technique

In the naval vessel, various pipes are of a great variety, as seamless steel pipe, welded steel pipe, bimetal tube or the like.Pipe passes through bulkhead or the deck is very frequent, and pipe certainly will be cut apart and overall sealing performance damages whole fire prevention when bulkhead that passes through fire protection requirement or deck, therefore is necessary to make to be recovered in the thermal insulation and the integrity of the separation of through part.If adopt methods such as traditional welding, because of thickness, thermal conductivity, the degree of expanding with heat and contract with cold of various pipes and steel plate, amplitude etc. is directly not identical when being vibrated, it is unavoidable that the joint produces metal fatigue, serious meeting causes sealability to descend, even pipe break, influence the navigation on naval vessel.So the fire-resistant sealing through-going device of pipeline newly developed should have the good fire resistance energy, again have good seal performance, easy for installationly can adapt to the requirement that various pipes run through.

At present, the fire-resistant sealing through-going device of domestic pipeline has a kind of pipeline through piece peculiar to vessel, this product mainly seals by ring-like sealing plug the sealing of pipeline, different pipe of all size and the different through-going device of all size are arranged on the naval vessel, will manufacture and design the different ring-like sealing plug of all size like this, design loaded down with trivial details, make or installation process in the sealability that error can influence the pipeline through-going device appears.Also has the fire-resistant seal arrangement of a kind of knockdown type pipeline, it is characterized in that pipeline outer wall is surrounded by one deck sheet rubber at least, remaining space is then with the empty sleeve pipe filling of non-incision between pipe and pipe way, pipe and inwall, empty sleeve pipe quality is softer on the one hand, the time meet obstructions in filling in through-going device can bend, harmful effect such as distortion, after empty on the other hand sleeve pipe installs, in gravity that produces because of the weight of the empty sleeve pipe in top and the using process because of reasons such as vibration can cause bottom distortion, the sinking of empty sleeve pipe, the space can occur on top, influence sealability.

Summary of the invention

The purpose of this utility model is: but a kind of fire-resistant sealing through-going device of pipeline of secondary shutoff is provided, and this through-going device adapts to various different pipes to be installed, quick and easy for installation, good seal performance, it is little to take up space, simple in structure, and the through-going device remaining space inside is as far as possible little.

Technical solution of the present utility model is: comprise a framework that can wear a pipe at least, the outer wall of each root pipe wraps up one deck fire-resistant seal at least, fire-resistant seal bar is installed between pipe and pipe way, pipe and inwall, be respectively equipped with the fire resistant sealant layer at the two ends of framework, the fire resistant sealant layer with fire-resistant seal, fire-resistant seal bar shutoff in framework.

But in the fire-resistant sealing through-going device of the pipeline of secondary shutoff of the present utility model, fire-resistant seal is a rectangular web-like pad, and this fills up the wide 20mm of thick 5mm.

But in the fire-resistant sealing through-going device of the pipeline of secondary shutoff of the present utility model, fire-resistant seal bar is the cylinder type solid bar, the long 200mm of this rod diameter 5-30mm.

But in the fire-resistant sealing through-going device of the pipeline of secondary shutoff of the present utility model, fire resistant sealant bed thickness 25-30mm.

During installation, framework is welded on bulkhead or the deck, and pipe at first is installed in framework, according to the diameter cutting fire-resistant seal of pipe, wraps up one deck fire-resistant seal at least in the pipe periphery then, and fire-resistant seal is fixed on the pipe; Secondly, the remaining space between pipe and pipe way, pipe and framework inwall is closely knit by fire-resistant seal bar filling; At last respectively reserve the 25-30mm space at the two ends of framework, the fire resistant sealant layer is sealed in the headspace at two ends, uses the instrument flat surface, guarantees sealing.

In the good through-going device of shutoff, if in the time of also need increasing pipe, with being arranged in the through-going device, the two ends in the vacant place that can pass for pipe cut off the fire resistant sealant layer with blade, extract fire-resistant seal bar out, again clog fire-resistant seal bar after the pipe of parcel fire-resistant seal passes, filling gets final product at the through-going device two ends with the fire resistant sealant layer again.

The utlity model has following advantage: 1. simple in structure, it is little to take up space; 2. fire-resistant seal is a rectangular web-like pad, can arbitrarily cut according to the diameter of pipe, and the pipe that adapts to various different-diameter sizes uses; 3. the remaining space that solid fire-resistant seal bar can make the remaining space of framework inside maybe might occur reduces, and guarantees sealability; 4. fire-resistant seal bar hardness increases, and can not be out of shape, twist when inserting framework, and is quick and easy for installation; 5. the requirement of secondary shutoff be can realize after installing, the increase or the minimizing of pipe realized; 6. have effects such as fire prevention, protection against rodents, anti-vibration, shock resistance.
