Abstract
The utility model belongs to the chemical technical field, relates to a corrosion resistant rubber sealing film for Wingins type gas cabinet consisting of two layers of facial glues (1, 3) using the fluororubber as the main material and a skeleton (2) positioned between two layers of facial glues (1, 3); the skeleton (2) between two layers of facial glues and two layers of facial glues (1, 3) are integrally vulcanized; and the skeleton (2) is the cord fabric weaved by the cord yarn and the fine single yarn. The utility model uses the structure of a layer of skeleton and two layers of facial glues to largely reduce the weight of the sealing film and bring great convenience for installing and dismantling in the premise of satisfying the strength; for the rubber layer uses the fluororubber with stronger corrosion resistance and good temperature resistance as the main material of the facial glue, so that the corrosion resistance of the sealing film is largely improved and the sealing film is used in the medium gas cabinet in the harsh environment; and the service life of the sealing film is 2-5 times of the sealing film made of the common rubber.
Description
Technical field
The utility model belongs to chemical technology field, is mainly concerned with a kind of Wei Jinsishi gas holder and uses the anti-corrosive rubber diaphragm seal, is used in strong corrosive media gas holders such as petrochemical industry gas holder, coke oven gas holder, also can be used for other corrosion resistance spread goods.
Background technology
The Wei Jinsishi gas holder has obtained using widely as the critical piece of petrochemical industry, steel plant's gas treatment.But the rubber seal membrane component that present Wei Jinsi gas holder uses mainly adopts neoprene, acrylonitrile-butadiene rubber, butyronitrile+PVC blend to be main rubber, and hermetically-sealed construction adopts the structure of two glue, three cloth; The rubber sealing film that with neoprene, acrylonitrile-butadiene rubber, butyronitrile+PVC blend is main rubber is when running into benzene, naphthalene, hydrogen sulfide, coal tar wet goods strong corrosive media; Be prone to bubbling, phenomenon such as ventilative in the rubber seal use of this material, the life-span is often shorter; Adopt the hermetically-sealed construction of two glue, three cloth to increase the quality of diaphragm seal again greatly, this give gas holder design, counterweight etc. be installed bring great inconvenience.
The patent of domestic relevant rubber sealing film is more, mainly contains patent No. CN 101290088A, the corrosion resistant compounded rubber seal membrane described in the patent; Fluorine adhesive plaster by the corrosion resistance that contacts with medium is strong is formed with the common adhesive plaster that contacts with the external world as the internal layer rubber membrane; Inside and outside intermembranously adopt adhesive bonding or non-caked use, have inside and outside film bonding difficulty though this product has stronger corrosion resistance, if non-caked; Inside and outside film is in released state; Inside and outsidely do not have a good diaphragm seal effect, the fatigue behaviour to product also has certain influence simultaneously, and structure is complicated; Rubber sealing film described in the CN 201179745Y patent is that a kind of to adopt the excellent hydrogenated nitrile-butadiene rubber of medium-resistance be material of main part, four glue, three cloth, five glue, four cloth sealing structure films, yet this structure have a shortcoming that cost is high, product quality is heavy.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model is to propose a kind of Wei Jinsishi gas holder to use the anti-corrosive rubber diaphragm seal.
For realizing that the present invention of foregoing invention task adopts following technical scheme:
A kind of Wei Jinsishi gas holder is used the anti-corrosive rubber diaphragm seal, described rubber sealing film by two-layer be the face glue of material of main part with the fluorubber, and the skeleton between two aspect glue constitutes; Skeleton between two aspect glue and the sulfuration of two aspect glue are one; The cord fabric of described skeleton for forming by cord fabric thread and the braiding of ramuscule single thread.
Described cord fabric is matrix pattern, M shape or 45 ° of X-shapes.
A kind of Wei Jinsishi gas holder that the utility model proposes is used the anti-corrosive rubber diaphragm seal; Adopted one deck skeleton and two-layer be the version of the face glue of material of main part with the fluorubber; Satisfying the weight that has reduced diaphragm seal itself under the prerequisite of intensity greatly, providing great convenience for installation, dismounting; Because it is material of main part that face glue has adopted fluorubber, therefore have the advantages that corrosion resistance is strong, temperature tolerance is good, the corrosion resistance of diaphragm seal is improved greatly, can be used in the harsh medium gas holder of environment; Be 2～5 times of common material rubber sealing film the service life of sealing film.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model.
Fig. 2, Fig. 3, Fig. 4 are the structural representation of skeleton in the utility model.
Among the figure: 1,3, face glue, 2, skeleton.
The specific embodiment
In conjunction with accompanying drawing and specific embodiment the utility model is explained:
As shown in Figure 1, a kind of Wei Jinsishi gas holder is used the anti-corrosive rubber diaphragm seal, and described rubber sealing film is the face glue 1,3 of material of main part with the fluorubber and is constituted at two aspect glue 1, skeleton 2 between 3 by two-layer; Be one in two aspect glue 1, skeleton 2 and two aspect glue, 1,3 bondings between 3, skeleton 2 plays booster action therein; The cord fabric of described skeleton for working out by cord fabric thread and ramuscule single thread.
Like Fig. 2, Fig. 3, shown in Figure 4, the cord fabric of working out with nylon or polyester etc. is matrix pattern, M shape, 45 ° of X-shapes.
During making, at first rubber is carried out in the two sides of skeleton 2, carry out two-sided rubberizing then, make skeleton 2 and two- layer rubber layer 1,3 bondings be one, after become a cylindric rubber sealing film after the sulfuration, seam for guaranteeing skeleton 2 and the bonding of face glue 1,3.
Claims (2)
1. Yi Zhong Wei Jinsishi gas holder is used the anti-corrosive rubber diaphragm seal, it is characterized in that: described rubber sealing film by two-layer be that the face glue (1,3) of material of main part and the skeleton (2) that is positioned between the two aspect glue (1,3) constitute with the fluorubber; Skeleton (2) between two aspect glue is one with two aspect glue (1,3) sulfuration; The cord fabric of described skeleton (2) for forming by cord fabric thread and the braiding of ramuscule single thread.
2. a kind of Wei Jinsishi gas holder according to claim 1 is used the anti-corrosive rubber diaphragm seal, it is characterized in that: described cord fabric is matrix pattern, M shape or 45 ° of X-shapes.
