Description
Technical field
The utility model relates to a kind of 45 degree of bend pipes, particularly to one decompression 45 degree of bend pipes of protecting against shock type.
Background technology
45 degree of bend pipes are widely used as pipe connecting component, in practice it has proved that, 45 degree of bend pipes in the market are structurally
Could be improved part, its interior media stream is more rapid, and noise is relatively big, and in bend pipe corner medium rheology to change stream right
The impulsive force of tube wall is very big, adds loss, not only produces considerable influence to the service life of bend pipe, and easily thus result in pipe
Wall bursting accident, brings inconvenience and harm to productive life.
Utility model content
In order to solve the problems referred to above, the utility model aims to provide one can effectively be reduced to tube wall impact, Jin Erbao
45 degree of bend pipes of decompression protecting against shock type of card tube wall safety.
The technical scheme of this decompression 45 degree of bend pipes of protecting against shock type is achieved in that
Described decompression 45 degree of bend pipes of protecting against shock type, including bent tubular body, an end of bent tubular body stretches out along its axis
Forming school extension, threaded first spoiler that is provided with in position near bent tubular body end in school extension, on the first spoiler
Offering some through round table-like discharge orifices, big one end, discharge orifice aperture is positioned at the first spoiler near the one of bent tubular body end
Side, little one end, discharge orifice aperture is positioned at the side near school extension end for first spoiler.
Further, described school extension inwall being disposed radially baffle plate, the first spoiler can be resisted against on baffle plate.
Further, described baffle plate is sector shape, has several, and circumference is uniformly fixed on school extension inwall.
Further, described baffle plate is circular, is fixedly installed on school extension inwall.
Further, it also threaded in the school extension between described school extension port and the first spoiler is provided with second
Spoiler, the second spoiler also offers some through round table-like discharge orifices, and big one end, discharge orifice aperture is positioned at the second choked flow
Plate is near the side of the first spoiler end, and little one end, discharge orifice aperture is positioned at the second spoiler near the one of school extension end
Side, forms depth adjustable Jie Xuliu district between the first spoiler and the second spoiler.
Further, the school extension outer tube wall between described school extension port and the second spoiler is further fixedly arranged on square
Offering the decontamination mouth being connected on the school extension tube wall of shape reinforcement block, reinforcement block and underface thereof, decontamination mouth coupling has cover plate,

It can be the connection of two element internals.For the ordinary skill in the art, on can being understood by concrete condition
State concrete meaning in the utility model for the term.
Describe the utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Decompression 45 degree of bend pipes of protecting against shock type described in the utility model, as it can be seen, include bent tubular body 1, of bent tubular body 1
End stretches out along its axis and forms school extension 2, and in school extension 2, the position of close bent tubular body 1 end is threaded is provided with
First spoiler 3, the first spoiler 3 offers some through round table-like discharge orifices 4, and big one end, discharge orifice 4 aperture is positioned at
One spoiler 3 is near the side of bent tubular body 1 end, and little one end, discharge orifice 4 aperture is positioned at the first spoiler 3 near school extension 2 end
The side in portion.
School extension 2 need to be used by 45 degree of bend pipes of this decompression protecting against shock type as medium entrance end, and it is right to be fixed with in school extension 2
The medium stream entering plays the first spoiler 3 of choked flow effect, it has some round table-like discharge orifices 4, thus will pour in expansion
Whole stock medium flow point in portion 2 deadens and breaks as some shallow bid medium streams, and in the process, the speed of shallow bid medium stream can increase
Add, but owing to medium stream one end little from discharge orifice 4 aperture flows to big one end, aperture, therefore flow through the medium velocity of discharge orifice 4 not
Can increase very big, the medium simultaneously flowing through discharge orifice 4 radially sprays, and interferes and energy between adjacent shallow bid medium stream
Amount consumption mutually, therefore generally speaking its momentum and pressure to tube wall has declined compared to whole stock medium stream, so that originally subtract
Pressure 45 degree of bend pipes of protecting against shock type have noise abatement, the function of anti-tube wall impact, use to extending 45 degree of bend pipes of this decompression protecting against shock type
In the life-span, the generation reducing tube wall bursting accident all has positive effect.
In 45 degree of bend pipes of this decompression protecting against shock type, described school extension 2 inwall baffle plate 5, the first choked flow are disposed radially
Plate 3 can be resisted against on baffle plate 5.
Specifically, described baffle plate 5 can have several in sector shape, and circumference is uniformly fixed on school extension 2 inwall.
Specifically, described baffle plate 5 can also be fixedly installed on school extension 2 inwall in circular.
In 45 degree of bend pipes of this decompression protecting against shock type, in the school extension 2 between described school extension 2 port and the first spoiler 3
Also threaded second spoiler 11 that is provided with, the second spoiler 11 also offers some through round table-like discharge orifices 4, discharge orifice
Big one end, 4 apertures is positioned at the side near the first spoiler 3 end for second spoiler 11, and little one end, discharge orifice 4 aperture is positioned at
Second spoiler 11, near the side of school extension 2 end, forms depth adjustable joint between the first spoiler 3 and the second spoiler 11
Xu Liu district 12, the media flow state entering Xu Liu district 12 through the second spoiler 11 accumulates in Xu Liu district 12, simultaneously from first
Spoiler 3 enters in bent tubular body 1, and the existence in Xu Liu district 12 can consume the momentum that medium stream is had, then superposition the second choked flow
Plate the 11st, the consumption to medium stream energy for first spoiler 3, thus strengthen further to medium stream decompression protecting against shock effect in pipe
Realize.
In 45 degree of bend pipes of this decompression protecting against shock type, outside the school extension 2 between described school extension 2 port and the second spoiler 11
It is further fixedly arranged on rectangular reinforcement block 10 on tube wall, school extension 2 tube wall of reinforcement block 10 and underface thereof offers and is connected
Decontamination mouth 6, decontamination mouth 6 coupling has a cover plate 7, and cover plate 7 is followed closely 8 with reinforcement block 10 by fastening and threadeded；
Being provided with corresponding groove on described cover plate the 7th, end face that reinforcement block 10 contacts, in groove, coupling has sealing ring
9。
In 45 degree of bend pipes of this decompression protecting against shock type, described decontamination mouth 6 cross section is oval poroid.
In 45 degree of bend pipes of this decompression protecting against shock type, described cover plate 7 thickness is not less than school extension 2 wall thickness.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in the utility model
Protection domain within.
