Abstract

The utility model relates to a novel environment-friendly and flame retardant single-tube multipath circular rubber module penetrating piece for leading various cables or pipelines to penetrate through the bulkheads of ships and adjacent walls of decks and buildings. The penetrating piece comprises a circular metal frame; a pair of rubber frames is arranged in the metal frame; rubber belts with better expansion property are wounded between the pair of rubber frames and on the cables or the pipelines; a plurality of layers of rubber sheets are arranged in each rubber frame; and a penetrating hole for allowing the cables or the pipelines to pass through is formed on the rubber sheet on the innermost layer. Therefore, the product cost can be greatly reduced, and the proper metal frames and different layers of rubber sheets can be simultaneously selected according to the cables and the caliber dimension of the pipelines, so that the penetrating piece realizes the standard production, a large amount of moulds is saved, the installation and the maintenance are more convenient simultaneously, and the installed pipelines or the cables are more attractive. In case of fire, the penetrating piece can quickly expand to block a channel between the walls or the bulkheads, thereby cutting off a fire source to spread to other compartments or rooms.

Description

The fire-retardant single tube multipath of novel environment friendly round rubber module penetrating item

Technical field

The utility model relates to a kind of pipeline through piece, relates in particular to a kind of various cable or pipeline carry out crossing cabin in boats and ships bulkhead, deck and building adjacent wall penetrating item.

Background technique

Pipeline through piece is mainly used in the passage that building room or the various electric wires of ship's space or other various pipelines run through, should guarantee to build the sealability between room or the ship's space, guarantee again under the situation that various accidents (as fire) occur, penetrating item can expand rapidly and cut off passage between building room or the ship's space, between each cabin of boats and ships and particularly important between each factory building of nuclear power plant.The conventional tube through-going device, employing is applied in the ingress pipe in the bulkhead through hole and is located in the interior through tube of this ingress pipe, between ingress pipe and through tube, be provided with the sealing plug of ring-type, as the patent No. is that 200520014290.1 Chinese utility model patent " a kind of pipeline through piece peculiar to vessel " discloses said structure, guaranteed the sealing effect between ingress pipe and the through tube, make the fireproof performance and the sealability of this pipeline through piece peculiar to vessel all comparatively desirable, and simple in structure, simple installation, take up space for a short time, and cost is also lower.But this penetrating item is unsatisfactory in actual use: 1. cables with different diameters or pipeline in use must adopt the penetrating item of different size, bring inconvenience for like this production of penetrating item, can not satisfy standardized production, simultaneously the perforate of building room or ship's space is also made troubles, the size of perforate must be carried out according to the penetrating item of different size; 2. the conjugation of the rubber framework of penetrating item and metal framework is not enough, easily is moved; 3. rubber framework and sheet rubber all adopt the good material of expansion character, and its cost is higher.

The model utility content

The utility model purpose is to provide the fire-retardant single tube multipath of a kind of novel environment friendly round rubber module penetrating item, adopt modular design, in the circular metal framework, be provided with a pair of rubber framework, twine the better rubber tape of expansion character between the two rubber frameworks, on cable or the pipeline, can reduce the fabricating cost of product so significantly.

The technical solution of the utility model is achieved in that

The fire-retardant single tube multipath of a kind of novel environment friendly round rubber module penetrating item, comprise the circular metal framework, be provided with the rubber framework in this metal framework, in this rubber framework, the several layers sheet rubber is arranged, form the penetration hole that current supply cable or pipeline pass at the innermost layer sheet rubber, it is characterized in that: described rubber framework is a pair of, twines rubber tape between this is to the rubber framework, on cable or the pipeline.

The sheet rubber of described rubber framework and every layer is by being put together more than the two halves at least.

Be provided with metal baffle at two ends, the described rubber framework outside, described rubber framework be fixed in the described metal framework by bolt.

The diameter of a described end metal baffle is greater than the internal diameter of described metal framework, and the diameter of the other end metal baffle is less than the internal diameter of described metal framework.

Described each rubber framework two ends all are provided with metal baffle, by bolt described rubber framework are fixed in the described metal framework.

The diameter of described outside metal baffle is greater than the internal diameter of described metal framework.

Described metal baffle is by being put together more than the two halves at least.

The utility model compared with prior art has following advantage:

1. be provided with a pair of rubber framework in the circular metal framework, between this is to the rubber framework, the better rubber tape of expansion character, the rubber framework can adopt the general material of expansibility, can reduce the fabricating cost of product on the one hand significantly; Can improve fire prevention and sealability between the cabin, between the room on the other hand,, passage between wall or the cabin wall be stopped up, cut off burning things which may cause a fire disaster and spread to other cabin or room in case the breaking out of fire phenomenon can expand rapidly.

2. this modularization penetrating item in use, can be according to cable or pipeline caliber size, choose the sheet rubber of the different numbers of plies and realize that cables with different diameters or pipeline pass, can make penetrating item realize standardized production like this, save a large amount of moulds, installation and maintenance simultaneously is convenient, and the hole that need not to open different bores on cabin wall or wall makes the pipeline of installation or cable more attractive in appearance.

3. because the sheet rubber of rubber framework and every layer can be by being put together more than the two halves at least, like this, rubber framework and the sheet rubber integral body that can be directly on the perforation cable at adjacent metal framework place or pipeline, directly be put together, then fill in the metal framework fast, and need not to penetrate from the end that connects cable or pipeline again, not only save time but also laborsaving.

4. be provided with metal baffle at rubber framework two ends, the rubber framework be fixed in the metal framework, guaranteed combining closely of rubber framework and metal framework, further improve the obstruction effect of rubber by bolt; Diameter one end of metal baffle is greater than the internal diameter of metal framework, and the other end guarantees the attractive in appearance of installation less than the internal diameter of metal framework.

5. on each rubber framework, be provided with metal baffle, improve the conjugation of rubber framework and metal framework on the one hand, make the both sides of penetrating item all very attractive in appearance on the other hand, can not occur in order to guarantee both conjugations, and outside metal baffle is tightened to metal framework the inside, influence that it is attractive in appearance.
