Technical field
The utility model relates to filling Sealing, specifically a kind of for being filled in the pump at rugged environment scene or the compound abrasive resistance sealing parts of valve chamber.
Background technique
Scene in a lot of rugged environment processings; its operating mode is severe; the equipment pump of working under this environment or valve often can be subject to the wearing and tearing of burn into foreign matter and the beating of axle of its medium; its Sealing can not effectively compensate and axle close contact again; pump or valve are leaked; medium leaks, decrease in efficiency, befouling environment.
In prior art, the pump under this work condition environment or valve maintenance are mostly adopted and change common fillers, press the gland of pump or valve or change pump or valve.But common fillers does not have elasticity in the material chamber of equipment pump or valve, if axle circular runout, just can not play compensating action, and common fillers do not have self-lubricating function yet, can not effectively lubricate axle, oneself wears no resistance, axle sleeve easily weares and teares, its product is short working life, and maintenance cost is high, is difficult for promoting.
Summary of the invention
The purpose of this utility model is according to the deficiencies in the prior art, a kind of surfacing is provided, rebound elasticity is strong and wear resistance is good, corrosion-resistant, and intensity is high, and the compound abrasive resistance sealing parts that compactness is good, the seal has self-lubricating function, and between its fiber, space is little, and after surface layer wearing and tearing, whole filler can be not loose, long service life is little to axle wearing and tearing.
The utility model provides a kind of compound abrasive resistance sealing parts, it is characterized in that: described Sealing comprises by four wear-resistant surface and four square hollow wear-resistant sleeves of strip that stiffening rib braiding forms that appearance is smooth, four stiffening ribs are distributed in the position of four knuckles of square hollow wear-resistant sleeve, hollow part at square hollow wear-resistant sleeve is filled with elastic core element, and the shape of described elastic core element is identical with the hollow part shape size of square hollow sleeve.
The further technological scheme of the utility model: four wear-resistant surfaces and four stiffening ribs of described square hollow wear-resistant sleeve are to adopt the inside and outside braiding of vertical four rail 32 ingot square knitting machine diagonal angles intersection to form, wherein wear-resistant surface is to be formed by the carbon fiber knit soaking after graphite, described stiffening rib is to be formed by kevlar fiber braiding, is distributed on four chines of square hollow wear-resistant sleeve.
The utility model is technological scheme preferably: described elastic core element is cylindrical strip, adopts silicone rubber or fluorine rubber to make.
The utility model is technological scheme preferably: described Sealing integral body is band shape or rope-like constructed, and its diameter is 3mm-75mm.
The utlity model has following beneficial effect:
(1) wear-resistant surface that the utility model is formed by carbon fiber knit by outside and four square hollow tubular structures that the stiffening rib being formed by kevlar fiber braiding forms, carbon fiber is through carbonization and graphitization processing and the micro crystal graphite material obtaining by organic fiber, compare with traditional fiber (GF), Young's modulus is that they are more than 3 times, insoluble not swollen in organic solvent, acid, alkali, corrosion resistance is transcendent, and due to after soaking in plumbago, be stained with a large amount of plumbagos, greatly improved its wear resistance and possessed self-lubricating function; The kevlar fiber in bight is strengthened rail and is had superhigh strength, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, its intensity is 5～6 times of steel wire, modulus is steel wire or glass fibre 2～3 times, toughness is 2 times of steel wire, and weight is only 1/5 left and right of steel wire, at the temperature of 560 degree, do not decompose, do not melt, it has good insulating properties and aging quality resistance, has very long life cycle;
(2) in the hollow tube being formed by fibrage, be filled with the elastic core element that silicone rubber or fluorine rubber are made, the water insoluble and any solvent of silicone rubber, nonpoisonous and tasteless, stable chemical nature, adsorption performance is high, good thermal stability, have higher mechanical strength etc.; Fluorine rubber is nontoxic, tasteless, do not fire (certainly putting out), has good heat-resisting, oil resistant, chemical resistance, good physical and mechanical properties and weather resisteant.
The utility model adopts the composite braided design of multiple material, has surfacing, and rebound elasticity is strong and wear resistance is good, and intensity is high, have self-lubricating function, compactness is good, and between fiber, space is little, after surface layer wearing and tearing, whole filler can be not loose, long service life, the features such as axle sleeve of not wearing and tearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-wear-resistant surface, 2-stiffening rib, 3-elastic core element
Embodiment
Below in conjunction with accompanying drawing, the technological scheme in the utility model is further illustrated.A kind of compound abrasive resistance sealing parts described in Fig. 1, it is characterized in that: described Sealing comprises by four wear-resistant surface 1 and four square hollow wear-resistant sleeves of strip that stiffening rib 2 braidings form that appearance is smooth, four stiffening ribs 2 are distributed in the position of four knuckles of square hollow wear-resistant sleeve, in the hollow part of square hollow wear-resistant sleeve, be filled with elastic core element 3, the shape of described elastic core element 3 is identical with the hollow part shape size of square hollow sleeve.During concrete braiding, first elastic core element 3 to be ready to, then use existing vertical four rail 32 ingot square knitting machines to adopt the method for the inside and outside braiding of diagonal angle intersection outside elastic core element 3, to be woven into by four wear-resistant surfaces 1 and four square hollow wear-resistant sleeves that stiffening rib 2 forms, and elastic core element 3 is coated togather closely to form a diameter be 3mm-75mm band shape or rope form Sealing, its diameter is consistent with the material cavity gap width in the middle of valve body or pump, just valve body or the sealing of stock chamber can be filled.During braiding, wherein walk eight spindles of four jiaos of tracks kevlar fiber is installed, other 24 spindles are installed carbon fiber, in braiding process, in carbon fiber outside, applying plumbago formation is graphite bisque, after braiding, just four wear-resistant surfaces 1 are all carbon fibre materials, four stiffening ribs 2 are all kevlar fibers, and wear-resistant surface and the accurate integrated by weaving of stiffening rib, can arbitrarily not unclamp.
