Description
Technical field
The utility model relates to cable and tubing sealing elastomer module and manufacture method thereof.
Background technique
In modern project, often cable or other pipeline need be passed different Spacers, such as building masonry wall, boats and ships hull and partition, electrical equipment bin etc., and the medium that requires to be sealed to prevent the Spacer both sides at cable or the pipeline place of passing exchanges, thereby keeps pressure medium, the temperature of requisite space, the stable and cleaning of composition.The function of Sealing except that the pressure that keeps container, prevent the erosion of flue dust and harmful gas system etc., also have fire-proof curtain, reduce the variation of system temperature, the anti-aging radiation hardness of improving system, explosion-proof and shockproof effect etc., thereby the civilian and industrial building that is used for various electric and electronic devices, boats and ships, track traffic, tunnelling works, communications equipment, oil drilling more and more and has relatively high expectations.
Cable or tubing Sealing are generally to be made up of one group of elastomer module and metal framework, metal partion (metp) and securing means.Elastomer module is the 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 Sealing.
T.Kreutz has introduced a kind of module at U. S. Patent 6,262 in 370 (authorize July 17 calendar year 2001 and give RoxtecAB).This module can and be positioned at groove multilayer blade by the overcoat of one side belt grooves and form.For cable and tubing with various outer diameter are complementary, should form technological scheme requirement corresponding blade of throwing off the different numbers of plies when constructing of module by the multilayer blade.
The Chinese patent ZL 200620040263.6 of Fanyou Seal Technology Co., Ltd., Shanghai has introduced the another kind of module that has groove in (on May 30th, 2007).This module groove itself has decorative pattern.This technological scheme realizes being complementary with the cable and the tubing of various outer diameter by the compression that changes the inside groove decorative pattern.
All there is defective in these two kinds of technological schemes.The former is because lamination coating inevitably causing certain space between the elastomer blade and between blade and the shell, causes sealability to be limited to.In addition, this generic module uses complicated operation, also can not utilize the waste that causes on the material again because of the blade of being thrown off.For the latter, because integral module system forms with commaterial, cable dimension and the coupling of module are different adjustment the by protruding pattern piece compression degree inside and outside the groove.In order to guarantee the adaptation between module size stability and the module, this technological scheme requires die body that certain rigidity (generally more than Shao Er A70 degree) is arranged.Thereby when being packaged in cable or tubing within the groove, convex portion and the surface of contact between cable or the outer pipe wall in the elastomer module groove are less, cause 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 is produced move or extract out.
In a word, the shortcoming of existing elastomer module comprises unreasonable structure, uses the operating method complexity, waste material, sealing is poor, anti-pulling is low, low to the cable dimension matching, and manufacture method complexity etc.
