Abstract
The invention discloses a flange for connecting two vertical steel tubes. The flange comprises an upper steel tube and a lower steel tube. An upper flange is fixed on the bottom end face of the upper steel tube. A lower flange is fixed on the top end face of the lower steel tube. A plurality of holes are formed in each of the upper flange and the lower flange. The flange is characterized in that a flange protecting cover is arranged on the upper steel tube; a top opening of the flange protecting cover encircles on the upper steel tube; a bottom opening of the flange protecting cover is provided with a retractable rope capable of fastening the bottom opening on the lower steel tube. The upper flange and the lower flange are fixedly connected through bolts, the flange protecting cover is unfolded to extend to the lower steel tube, the retractable rope is tightened, and accordingly, the whole flange is protected well by the flange protecting cover. Only one layer rather than multiple layers of material is needed, so that materials are saved, the flange is flexible to use and reusable, and the flange protecting cover can be detached conveniently for inspection and maintenance.
Description
Technical field
The present invention relates to a kind of for connecting the flange of two vertical steel pipes.
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, by bolton together, has completed connection.It is the important Placement of pipeline construction that American Standard flange connects, some pipe fittings and equipment, especially steel pipe, carried flange plate, also be to belong to flange to connect, connect easy to use, can bear larger pressure, but when 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 enclosed construction of next flange protection cover is the destroyed object that does not reach protection easily.
Summary of the invention
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 invention is to provide; flange plate, steel pipe and flange protection cover are arranged to an integral body; 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 present invention 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.
With bolt, upper flange plate is fixedly connected with lower flange; 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 identical object equally.
The invention has the beneficial effects as follows: easy to use, flexible, can well protect flange, save material, reusable, convenient for maintaining.Further, prevent flange protection cover top water inlet corrosion flange.
