Abstract

The utility model discloses a reducing connecting flange which comprises a flange disk. The flange disk comprises an upper connecting disk and a lower connecting disk. A connecting column is arranged between the upper connecting disk and the lower connecting disk and is provided with a plurality of fixing ribs. The inner diameter of the upper connecting disk is lower than the inner diameter of the lower connecting disk. The flange disk is formed in a casting mode. The reducing connecting flange overcomes the defects in the prior art, is simple in design and reasonable in structure. Moreover through the arrangement of two different tube diameters on flange connection and through casting forming, the reducing connecting flange is simple in production technology and low in manufacturing cost.

Description

A kind of reducing adpting flange
Technical field
Model utility relates to the adpting flange technical field, specifically belongs to a kind of reducing adpting flange.
Background technique
Flange is main connection set, also usually adopts flange to connect at the pipe joint place.But in the caliber of some ad hoc requirement, need to diminish in the caliber outlet, increase flow rate of liquid in the pipeline.Existing flange bore is the same can't be realized, has now mainly to realize by tapered pipeline, and the tapered pipeline processing technology is complicated, and cost of production is high.
The model utility content
The purpose of model utility has provided a kind of reducing adpting flange, has overcome the deficiencies in the prior art, and simplicity of design is rational in infrastructure, by connecting at flange two different tube diameters is set, and simple by the casting production technology, fabricating cost is low.
The technological scheme that model utility adopts is as follows:
A kind of reducing adpting flange comprises flange plate, and described flange plate comprises land and lower land, be provided with attachment post between the upper and lower land, attachment post is provided with a plurality of fixedly muscle, and upper land internal diameter is less than lower land internal diameter, and flange plate is casting.
Have a plurality of mounting holes on the described lower land.
Compared with the prior art, the beneficial effect of model utility is as follows:
Model utility arranges two different tube diameters by connecting at flange, and simple by the cast form production technology, fabricating cost is low.
Description of drawings
Fig. 1 is the structural representation of model utility.
Embodiment
Referring to accompanying drawing, a kind of reducing adpting flange, comprise flange plate, flange plate comprises land 1 and lower land 2, is provided with attachment post between the upper and lower land, attachment post is provided with a plurality of fixedly muscle 3, upper land 1 internal diameter is less than lower land 2 internal diameters, and flange plate is casting, has a plurality of mounting holes 101 on the lower land 1, simple by the casting production technology, fabricating cost is low.
