The protecting tube 5 is through the inside of the ingress pipe 4, and the outer diameter of protecting tube 5 accounts for the 2/3~3/ of 4 internal diameter of ingress pipe
4.The protecting tube 5 is large aperture pipeline, in can accommodate the pipeline 6 of 1 or more different size.By being arranged in protecting tube 5
Pipeline 6 can use protecting tube and further promote the fire protecting performance that entire pipeline runs through device.
The pipeline 6 is corrosion-resistant, incendivity pipeline, and such as plastic tube or glass reinforced plastic pipe, rather than steel pipe, iron pipe etc. are solderable
The pipeline connect.The pipeline 6 helps to promote the Corrosion Protection that entire pipeline runs through device.
The length of the protecting tube 5 is less than the length of the ingress pipe 4, and the both ends of protecting tube 5 are located at the inside of ingress pipe
Filled with fire-proof sealing filling 7, to be equal to described lead positioned at the thickness of the sealing fire-proof packing 7 of 5 any end of protecting tube
Enter the half of the difference of the length of pipe 4 and the protecting tube 5, it is therefore preferable to 25~35mm.
The also fire-proof sealing filling is filled between the inner wall of the ingress pipe 4 and the outside wall surface of the protecting tube 5
7.By the way that fire-proof sealing filling will be stuffed entirely in the whole region between the inner wall of ingress pipe 4 and the outside wall surface of protecting tube 5,
On the one hand facilitate further lift line and run through the fire prevention of device, sealing performance, prevent end fire prevention, sealing performance deficiency from drawing
The infiltration that rises, leakage flue gas；On the other hand, it filled up in above-mentioned space, tamp fire-proof sealing filling and can have
Effect prevents pipeline from collapsing and causes the entrance or diffusion of water flow or flue gas, and lift line runs through the general safety protective performance of device.
Preferably, between the adjacent pipeline 6, it is close that the fire prevention is also filled between pipeline 6 and the inner wall of protecting tube 5
Packing material 7.Fire-proof sealing filling is filled in 5 internal clearance of protecting tube, on the one hand in the inner wall of ingress pipe 4 and the protecting tube
Between 5 outside wall surface on the basis of fire-proof sealing filling, further lift line runs through the fire prevention of device entirety, sealing performance；
It on the other hand will protection on the basis of fire-proof sealing filling between the inner wall of ingress pipe 4 and the outside wall surface of the protecting tube 5
The internal clearance of pipe 5 is filled up, is tamped, and further prevents pipeline to collapse and causes the entrance or diffusion of water flow or flue gas, lift line
Through the general safety protective performance of device.
Above-mentioned sealing fire-proof packing 7 is intumescent system, is expanded rapidly after encountering open fire, and expansion multiplying power is 10~25 times,
The pore of pipeline can be effectively sealed against, and tamp pore, guarantee it is water-tight in the case where 0.1MPa hydraulic pressure, to guarantee to lose
Fire or the pipeline in water inlet cabin do not interfere with next door cabin through device position.
Specifically, the fireproof sealing material includes following parts by weight of component: 100 parts of epoxy resin, expanded graphite 20~
30 parts, 15~20 parts of IFR fire retardant, 8~10 parts of graphite oxide, 20~30 parts of adhesive of fire prevention, 30~50 parts of reinforcing fiber, sky

Embodiment 2
The difference from embodiment 1 is that the Shipbuilding pipe road is connect through device with deck 2.The outside wall surface of the protecting tube 5
One layer of fire guard 8 is also wound with positioned at the part of the ingress pipe 4.Since deck 2 may be by outer during shipping row
The impact of power makes protecting tube 5 of the pipeline in device generate slight movement, to influence sealing performance.Therefore, by
One layer of fire guard is wound in the outside wall surface of protecting tube 5, on the one hand promotes high temperature resistant, fire resisting, the pressure-resistant performance of protecting tube 5, it is another
Aspect effectively prevent the slight movement of protecting tube 5, and lift line runs through the sealing performance of device entirety.
The present invention runs through device at a kind of Shipbuilding pipe road, by being arranged pipeline in protecting tube, and by protecting tube with
Fireproof sealing material is filled up in gap between ingress pipe, on the one hand effectively increases the fire protecting performance that pipeline runs through device entirety
With sealing waterproof, smoke retaining energy, the structural strength that pipeline runs through device entirety is on the other hand improved, pipeline is effectively prevent to collapse
The entrance or diffusion of water flow or flue gas are caused, lift line runs through the general safety protective performance of device.
Pipeline of the invention runs through device, has the function of excellent fire resisting, back-fire relief and blocks water, and burns by 1 hour
After test, it is still resistant to the hydraulic pressure (relative to 10 meters of deep water pressures) of 0.1MPa, can effectively ensure that the pipeline in the cabin that catches fire through department
The cabin in next door is not interfered with.
In the description of the present invention, it should be noted that the instruction such as term " on ", "lower", "left", "right", "inner", "outside"
Orientation or positional relationship be based on the orientation or positional relationship shown in the drawings or the invention product using when usually put
Orientation or positional relationship, be merely for convenience of description of the present invention and simplification of the description, rather than the device of indication or suggestion meaning
Or element must have a particular orientation, be constructed and operated in a specific orientation, therefore be not considered as limiting the invention.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, and comes for those skilled in the art
It says, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any modification, equivalent
Replacement, improvement etc., should all be included in the protection scope of the present invention.
