Abstract
The utility model relates to a connecting component applied between steam pipelines of different diameters and particularly provides a same-bottom eccentric reducing pipe, wherein the bottom of the eccentric reducing pipe is kept at the same horizontal position and axes of pipelines of different diameter are not on the same straight line and are parallel to each other. According to the technical scheme of the utility model, the same-bottom eccentric reducing pipe mainly comprises working pipes, an outer protective steel pipe, a heat insulation layer and a transportation positioning assembly. The working pipes are composed of a working pipe large-diameter pipe, a working pipe reducing pipe and a working pipe small-diameter pipe, wherein the working pipe large-diameter pipe, the working pipe reducing pipe and the working pipe small-diameter pipe are welded together in the square groove weld manner. The same-bottom eccentric reducing pipe is mainly applied to a thermal pipeline network for conveying high-temperature media, such as steam and the like. Meanwhile, the ponding problem at the bottom of the connecting part of pipelines of different diameters can be well solved. In addition, the corrosion of water to the pipelines can also be avoided.

Background technique
At present in heat distribution pipe network due to delivering vapor high temperature media, when pipeline needs reducing or three-way pipe etc. join two ends non-indentical tubes time, need to use reducer connected element to be connected.Consider the problem of BOP water, avoid the corrosion of water to pipeline, need a kind of novel reducer pipe fitting of research and design, it is very necessary overcoming existing problem in prior art.For newly-built pipeline, the mode that generally adopts reducer and the combination of other pipe fittings to manufacture.
Summary of the invention
The technological scheme that the utility model adopted is for achieving the above object: eccentric reducer of a kind of same end, comprise working pipe 1, working pipe 1 is comprised of working pipe large-diameter pipe 11, working pipe reducer 12 and working pipe small diameter tube 13, also comprise external protective steel tube 3, transportation positioning component 4, thermal insulation layer 6, described working pipe large-diameter pipe 11 and working pipe small diameter tube 13 are welded to connect by straight mouthful with working pipe reducer 12 respectively, described thermal insulation layer 6 is arranged between working pipe 1 and external protective steel tube 3, and described transportation positioning component 4 is arranged at this reducer port.
The utility model can further be limited to transportation positioning component 4 arranged outside mouth of pipe grommet 2, and the working pipe 1 during by use mouth of pipe grommet 2 and the position of external protective steel tube 3 keep relative fixing.
In order better to protect working pipe 1, can also outside external protective steel tube 3, add again the anticorrosion protective coating 5 of one deck simultaneously.
The utility model is mainly used in the heat distribution pipe network of the high temperature medias such as delivering vapor, can be good at solving reducer joint BOP water problem simultaneously, has avoided the corrosion of water to pipeline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1. working pipe, 11. working pipe large-diameter pipes, 12. working pipe reducers, 13. working pipe small diameter tube 2. mouth of pipe grommets, 3. external protective steel tube, 4. transportation positioning component, 5. anticorrosion protective coating, 6. thermal insulation layer.
Embodiment
Below in conjunction with accompanying drawing, provide specific embodiment of the utility model:
As shown in Fig. 1 the utility model structural representation, this is connected by working pipe reducer 12 with working pipe small diameter tube 13 with end eccentric reducer working pipe large-diameter pipe 11, and jointing adopts straight mouthful to be welded and fixed.At working pipe 1 skin, add external protective steel tube 3, filling heat insulating wall 6 between working pipe 1 and external protective steel tube 3.Port at this with end eccentric reducer is provided with transportation positioning component 4, is used for fixing external protective steel tube, and makes the position of working pipe 1 and external protective steel tube 3 keep relative fixing by mouth of pipe grommet 2.
In addition, outside the utility model external protective steel tube 3, add the anticorrosion protective coating 5 of one deck and can well protect external protective steel tube 3, and then working pipe 1 is played to better protection effect.
Meanwhile, thermal insulation layer 6 optimization polyurethanes or glass wool in the present embodiment.
