Abstract
The invention relates to a rubber sleeve used for protecting a coating on the outer surface of a hole of a carbon steel flange against mechanical damage. The protective rubber sleeve is placed into a bolt hole of the flange. The protective rubber sleeve is arranged in the bolt hole in a sleeved mode and is in interference fit with the bolt hole. When the flange is in butt joint with another flange or a flange cover in a fastened mode, a bolt penetrates through an elastic washer, a flat washer and the protective rubber sleeve to conduct tightening. The protective rubber sleeve is made of a nonmetallic material and is arranged between the flat washer and the flange face to avoid direct mechanical contact between the flat washer and the flange face, so that the coating is protected.
Description
Technical field
The present invention relates to a kind of protective boot, being a kind of for protecting the gum cover that simple steel flange hole external surface coating is not mechanically damaged specifically, belonging to coatings art.
Background technique
In people's modern life, plumbing equipment is very common, and because carbon steel equipment is cheap in water work, long service life after anticorrosion, good decorative property, life class is high, extensively favors by people.All anti-corrosion spray is needed in modern technologies middle-carbon steel plumbing equipment, its coating is easy to be mechanically damaged, especially the upper and lower surface of flange hole and flange hole position, when carrying out bolton, mechanical friction pretightening force causes the coating of bolt hole position just to be damaged before product export, just get rusty very soon by air corrosion after dispatching from the factory, cause whole coating from then on get rusty in position, coating shedding extremely affects product class and life-span.
Summary of the invention
The object of the invention is to, a kind of protective boot is provided, to solve in above carbon steel plumbing equipment flange bolt hole position coating when flange assembling is fastening and be subject to the technical barrier that mechanical deterioration causes coating shedding, equipment gets rusty.
The technical solution adopted for the present invention to solve the technical problems is: place protective boot in flange bolt hole, protective boot is placed in bolt hole and bolt hole interference fit, when flange docks fastening with flange or blind flange, bolt carries out fastening through bullet pad, plain cushion, protective boot, protective boot is non-metallic material, be placed between plain cushion and flanged surface, prevent plain cushion from contacting with flanged surface direct mechanical, play the effect of barrier coating.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure, 1, bolt, 2, bullet pad, 3, plain cushion, 4, protective boot, 5, flange.
Embodiment
The present invention relates to a kind of for protecting the gum cover that simple steel flange hole external surface coating is not mechanically damaged, embodiment is as follows:
1) when carbon steel water work assembles after spray coating; first protective boot (4) is enclosed within flange (5) bolt hole; bolt (1) puts into bullet pad (2), plain cushion (3) successively; insert in flange (1) bolt hole through protective boot (4) afterwards; carry out bolton; because gum cover (4) is positioned over the mechanical friction effectively preventing between plain cushion (3) and flange (5) upper surface causing during bolton, flange coating can be protected not to be damaged.
Claims (1)
1. a protective boot, it is characterized in that being placed between plain cushion and flanged surface, be positioned in bolt hole with bolt hole interference fit.
