Description
Technical field
The utility model relates to a kind of airtight, fire-resistant communication cabin component device of the many cables of watertightness, and the characteristics of this cable communication cabin component are reserved space and the passage that carries out the follow-up dilatation of cable for it is inner, are convenient to the increase and the maintenance of cable.This device is widely used in the logical layer fire proof seal behind the logical cabin of cable in the newly-built and boats and ships transformed in shipbuilding industry, the ocean engineering, the offshore oil platform.
Background technology
Requirement according to International Electrotechnical Commission (I.E.C), International Convention for the Safety of Life at Sea (SOLAS) and China's ship construction standard, for satisfying the Ship's Insubmeribility design, satisfy the basic demand of fire safety, when cable penetration watertight next door (deck), need seal at the deck and the bulkhead place of cable penetration, not influenced by it with watertight and the fire integrity that guarantees hull.
Because cable penetrating fire proof seal device has great significance to boats and ships vitality, research to the cable fire-proof sealing is also more deep, new material has obtained employing, performance is constantly improved raising, develop into not only not only airtight but also fireproof device of watertight from simple watertight fittings, simple firebreak device, further increased low smoke, zero halogen low toxicity performance more again, that adopts at present both at home and abroad extensively mainly contains filling type fire proof seal device and modular fire proof seal device.
Chinese patent literature discloses a kind of preparation method (CN101037583) of filling type cable fire-proof sealing filling, and this invention originally relates to a kind of shipboard cable that is used for and runs through the fire-proof sealing filling at raceway groove and hole and preparation method thereof.This inventive method adopts kaolin 10～20%, talcum powder 5～10%, silicon powder 30～50%; As the aluminium hydroxide 10～20% of fire retardant, hydration zinc borate 5～10%, magnesium hydroxide 10～20%; Wherein the proportioning of base-material and fire retardant is 1: 1～2.3: 1; Also add coagulating agent calcium sulfate, calcium chloride, magnesium chloride and sodium carbonate in addition, its addition is that the total amount 100% with base-material and fire retardant serves as to calculate benchmark, replenishes in addition to add above-mentioned four kinds of coagulating agents and respectively be respectively 20～4% again.Earlier coagulating agent is added water and stir and mixedly make slurries, when reality is used, these slurries are joined in the Powdered batch of above-mentioned base-material and fire retardant, stir, promptly get the pasty state fire-proof sealing filling after mixing through abundant stirring with High-efficient Stirrer.Patent documentation CN2596638 discloses a kind of modular cable seal, and the sealing part comprises: seal half part, roughly be a parallelepiped-shaped, be provided with the cable passage of concavity in a side, the anchor ring periphery of cable passage is provided with groove; The additional part that pastes is made up of at least two pasters that link to each other in twos, and the anchor ring that pastes the part bottom is provided with and seals the projection that the groove on half part is complementary, and projection is complementary with sealing half part upper groove.Adopt modular cable seal of the present utility model, not only can adapt to the cable of various outer diameter and the seal of pipeline, and make the sealing part when reality is used, can improve operating personnel's operating efficiency.
The high strength that filling type sealing device filler is had after solidifying is that follow-up increase cable has caused great inconvenience, and the cable of having laid can't be extracted out again, can cause the waste of cable construction to a certain extent.Simultaneously, the proportion of filling type fire proof seal device is bigger, the anti-vibration performance is poor, and the application in special boats such as warship can be subjected to certain restriction.
When using the modular sealing device, because the difference of cable size, cabling need be taken time and be put corresponding cable, construction technology complexity, long construction period in advance on different cable size block rubber positions.When using modular fire proof seal device, the cable box requirement on machining accuracy is than higher, to guarantee tight seal between rubber module and the cable box.
