Abstract
The utility model gives a kind of metallic conduit flexible link, including rubber hose, the first connecting tube and the second connecting tube, and rubber hose both ends are separately positioned between the inlet pipeline and outlet conduit of outside；The internal diameter of first connecting tube is more than the external diameter of the second connecting tube, one end of first connecting tube connects with the inlet pipeline of outside, the other end of first connecting tube is stretched into one end of the second connecting tube, the other end of second connecting tube is connected with the outlet conduit of outside, and rubber hose is sleeved on the outside of the junction of the first connecting tube and the second connecting tube.According to the flow direction of slurry, first connecting tube is arranged on equipment end slurry entrance point, second connecting tube is arranged on slurry outlet end, when rubber hose because temperature and vibration understand up-down stretch and shortening, because the first connecting tube and the second connecting tube side wall are smooth, there is no resistance to slurry, so pulp flow can be more unobstructed, is not easy to be worn by slurry, service life length, reduce and produce hanging situation, ensure subsequent product quality.
Description
Technical field
A kind of attachment means of metallic conduit are the utility model is related to, connects and uses between more particularly to a kind of metallic conduit
Flexible device.
Background technology
Substantial amounts of rubber is used to be flexible coupling in reconstituted tobacco production technology, in pipeline, various fiberizers, large-scale vacuum
Pumping unit inlet and outlet is all to be connected by being flexible coupling with pipeline, and it is to be used to play flexible connection between metallic conduit to be flexible coupling
The hollow rubber product of effect, can reduce vibration and noise, and can to frequently changing because of temperature caused by expanded with heat and contract with cold compensation
Effect.But be flexible coupling in use there is also some problems, first, easily abrasion needs frequently to change, second, soft company
Connect that typically mid diameter is big, and both sides are directly small, similar ball-type, the part of such intermediate projections can produce to the flow velocity of slurry
Inhibition, while once have abrasion, hanging situation will be produced, being flexible coupling in pipeline cleaning, it is clean to be not easy.It is sordid
Slurry time length can produce rotten, and certain influence can be produced on subsequent product quality.
Utility model content
It is flexible that technical problem to be solved in the utility model is to provide metallic conduit a kind of rational in infrastructure, easy to use
Attachment means, the metallic conduit flexible link can effectively extend rubber and be flexible coupling service life.
In order to solve the above technical problems, the utility model provides a kind of metallic conduit flexible link, comprise at least
Rubber hose, rubber hose both ends are separately positioned between the inlet pipeline and outlet conduit of outside；
Also including the first connecting tube and the second connecting tube, the internal diameter of the first connecting tube is more than the external diameter of the second connecting tube, the
One end of one connecting tube is connected with the inlet pipeline of outside, and the other end of the first connecting tube is stretched into one end of the second connecting tube,
The other end of second connecting tube connects with the outlet conduit of outside, and rubber hose is sleeved on the first connecting tube and the second connecting tube
On the outside of junction.
After such structure, according to the flow direction of slurry, the first connecting tube of small internal diameter is arranged on equipment end slurry
Entrance point, the second connecting tube of large diameter are arranged on slurry outlet end, when rubber hose because temperature and vibration can up-down stretch
And shortening, because the first connecting tube and the second connecting tube side wall are smooth, there is no resistance to slurry, such pulp flow can be more logical
Freely, it is not easy to be worn by slurry, service life length.
The utility model is a kind of to extend rubber hose service life, reduces the maintenance frequency and cost, reduces rubber hose
Abrasion, reduce and produce hanging situation, ensure subsequent product quality.
Understand technology contents of the present utility model in order to clearer, below by this metallic conduit flexible link referred to as
For the present apparatus.
Connected between the first connecting tube and inlet pipeline of the present apparatus by flange, between the second connecting tube and outlet conduit
Connected also by flange；After such structure, facilitate the first connecting tube and the second connecting tube and outside inlet pipeline and
Outlet conduit connects.
The internal diameter of first connecting tube of the present apparatus is bigger 0.25mm than the external diameter of the second connecting tube；After such structure,
By the difference for the caliber for setting the first connecting tube and the second connecting tube, that is, ensure that the two has the gap that can be relatively moved, and
And a large amount of leakages of slurries will not be caused.
The first connecting tube and the second connecting tube of the present apparatus are stainless steel；After such structure, stainless steel gold
Accessory has wearability and corrosion resistance, and is easily obtained, suitable for the needs of the present apparatus.
Brief description of the drawings
Fig. 1 is the sectional view of the use state top view of present apparatus embodiment.
Embodiment
As shown in Figure 1
The present apparatus includes rubber hose 1, the first connecting tube 2, the second connecting tube 3, first flange component and second flange group
Part.
First connecting tube 2 and the second connecting tube 3 are all metal tube, and the material of the two connects usually using 304 stainless steels, first
The pipe thickness of 2 and second connecting tube of adapter 3 is all 3mm, and the internal diameter of the first connecting tube 2 is bigger than the external diameter of the second connecting tube 3
0.25mm, the rear portion of the first connecting tube 2 are stretched into the endoporus of the second connecting tube 3.
First flange component includes first flange disk 41 and first flange seat 42, and first flange disk 41 is welded on the first connection
On the anterior end outer wall of pipe 2, first flange seat 42 is welded on the end of inlet pipeline 7 of outside, first flange disk 41 and first
It is threadably secured between flange seat 42, and sealing ring 5 is provided between first flange disk 41 and first flange seat 42；
Similarly, second flange component includes second flange disk 61 and second flange seat 62, and second flange disk 61 is welded on
On the rear end outer wall of two connecting tubes 3, second flange seat 62 is welded on the end of outlet conduit 8 of outside, second flange seat 62
It is threadably secured between second flange seat 62, and sealing ring 5 is provided between second flange disk 61 and second flange seat 62.
Rubber hose 1 is sleeved on the outside of the junction of the first connecting tube 2 and the second connecting tube 3, rubber hose one end and the
One ring flange 41 is fixed.
In use, when the temperature of rubber hose 1 and vibration can up-down stretch and shortening, the first connecting tube 2 and the second connecting tubes 3
Between have a 0.25mm gap, rubber hose 1 with the two stretching and can shorten and slide up and down, due to the He of the first connecting tube 2
The side wall of second connecting tube 3 is smooth, does not have resistance to slurry（The flow direction of slurry is as shown in the direction of arrow in Fig. 1）, so
Pulp flow can be more unobstructed, while stainless steel metal is not easy to be worn by slurry, service life length, works as metal more than rubber wear-resisting
Pipe abrasion need only also change size metal tube to a certain extent.
Above-described is only a kind of embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as
Belong to the scope of protection of the utility model.
