Description
The divisional application of the application's to be application number be application for a patent for invention of 200810183797.8.
Technical field
The present invention relates to cable and pipe sealing elastic body module and manufacture method thereof.
Background technique
In modern project, often need cable or other pipeline to pass different Spacers, such as building masonry wall, Ship body and partition, type electrical appliance cabinet etc., and require to be sealed to prevent the medium on Spacer both sides from exchanging through place at cable or pipeline, thus keep the stable and clean of the pressure medium of requisite space, temperature, composition.The function of Sealing is except keeping the pressure of container, preventing flue dust and harmful gas to except the erosion of system etc., also have fire-proof curtain, reduce the change of system temperature, improve the anti-aging radiation hardness of system, explosion-proof and shockproof effect etc., thus more and more for various Electrical connections, boats and ships, track traffic, tunnelling works, communications equipment, oil drilling and require in higher civilian and industrial building.
Cable or tubing Sealing are generally made up of one group of elastomer module and metal framework, metal partion (metp) and securing means.Elastomer module is the most most important component units of fundamental sum (M.Twist and A.Platt, U. S. Patent 4,733, are authorized and given Hawke Cable Glands Limited on March 22nd, 016,1988) in the seal.
T.Kreutz, at U. S. Patent 6, describes a kind of module in 262,370 (July 17 calendar year 2001, RoxtecAB was given in mandate).This module and can be positioned at groove multiple layers of vanes and forms by the overcoat of one side belt grooves.For matching with the cable and tubing of various outer diameter, the corresponding blade throwing off the different number of plies when constructing should be required by the technological scheme of multiple layers of vanes comprising modules.
The another kind of module with groove is described in the Chinese patent ZL200620040263.6 (on May 30th, 2007) of Fanyou Seal Technology Co., Ltd., Shanghai.This module groove itself is with decorative pattern.This technological scheme realizes matching with the cable of various outer diameter and tubing by the compression changing inside groove decorative pattern.
These two kinds of technological schemes all existing defects.The former is due to lamination coating, inevitably between elastomer blade and between blade and shell, causes certain space, causes sealability to be limited to.In addition, this generic module uses complicated operation, also causes the waste on material because not carried out utilizing by the blade thrown off again.For the latter, because integral module system commaterial forms, cable dimension and the coupling of module are adjusted by the different of protruding pattern block compression degree inside and outside groove.In order to ensure the adaptation between module size stability and module, this technological scheme requires that die body has certain hardness (generally more than Shao Er A70 degree).Thus, when cable or tubing being packaged within groove, the surface of contact between the convex portion in elastomer module groove and cable or outer pipe wall is less, causes the decline of seal degree.In addition, because the frictional force of high hardness elastomer and cable and outer pipe wall is little, cable or tubing during at high pressure or at cable or tube-drawing, may be made to produce mobile or extract out.
In a word, the shortcoming of existing elastomer module comprises unreasonable structure, use that operating method is complicated, waste material, sealing is poor, anti-pulling is low, low to cable dimension matching, and manufacture method complexity etc.
