Background technique
It is a kind of releasable connection that American Standard flange connects, and is two pipelines, pipe fitting or equipment, is first fixed on separately on a flange plate, between two flange plate, adds flange gasket, with bolton together, completed connection.It is the important Placement of pipeline construction that American Standard flange connects, some pipe fittings and equipment, especially steel pipe, carry flange plate, also be to belong to flange to connect, connect easy to use, can bear larger pressure, but in the time that flange connects two vertical steel pipes, in order to protect flange plate, prevent the corrosion of flange plate, can put separately in flange plate outside a flange protection cover, because being puts separately a flange protection cover from outside, first need to be wound around multilayer, waste material, thereby the secondly easily destroyed object that does not reach protection of the enclosed construction of flange protection cover.
Model utility content
For the problems referred to above; it is a kind of for connecting the flange of two vertical steel pipes that main purpose of the present utility model is to provide; flange plate, steel pipe and flange protection cover are arranged to an entirety; easy to use, flexible; can well protect flange; further, prevent flange protection cover top water inlet corrosion flange.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
For connecting the flange of two vertical steel pipes; comprise steel pipe and lower steel pipe; described upper steel pipe bottom end is fixed with a upper flange plate; described lower steel pipe top end face is fixed with a lower flange; on upper flange plate and lower flange, be provided with several eyelets, it is characterized in that, on upper steel pipe, be provided with a flange protection cover; the open top of described flange protection cover is looped around on steel pipe, is provided with and bottom opening can be fastened on to the flexible rope on lower steel pipe on the bottom opening of described flange protection cover.
Upper flange plate is fixedly connected with lower flange with bolt; then launch flange safety cover; flange protection cover is stretched over to lower steel pipe, tightens up flexible rope, whole flange has all well been protected by flange protection cover; only with layer of material; need not be wound around multilayer, save material, and use flexibly; conveniently untie flange protection cover and check, keep in repair, reusable.
Further, for preventing flange protection cover top water inlet corrosion flange, can adopt two schemes: the first scheme: be positioned on the upper steel pipe at flange protection cover open top top, be provided with the moulding of upper steel pipe integrally casting and around the projection of upper steel pipe, described projection is downward-sloping, rainwater can flow to projection along upper steel pipe and then drop onto flange protection cover side, and the open top of flange protection cover has been protected in projection inner side, does not worry the situation that rainwater flows into; First scheme: on upper steel pipe, be provided with the moulding of upper steel pipe integrally casting and around on the annular groove of steel pipe; the open top of flange protection cover is fixed in annular groove; the open top of flange protection cover has been protected in annular groove, can reach equally identical object.
The beneficial effects of the utility model are: easy to use, flexible, can well protect flange, and save material, reusable, convenient for maintaining.Further, prevent flange protection cover top water inlet corrosion flange.
