Abstract
The invention discloses a kind of pressure duct multiple-pass joint, including inner and outer tubes, described outer tube sleeve is contained in outside inner tube and can rotate around inner tube, some through holes it are provided with in said inner tube, it is provided with some shunting interfaces, the aperture of described shunting interface and the equal diameters of through hole with through hole relevant position on described outer tube.A kind of pressure duct multiple-pass joint provided by the present invention, thus it is possible to vary the pore size of shunting interface, thus reach to change velocity in pipes and pressure, the application being suitable in pressure duct.
Description
Technical field
The present invention relates to a kind of pressure duct multiple-pass joint, belong to high-pressure pipe member field.
Background technology
Multiple-pass joint is for controlling the shunting of liquid or gas in pipe-line system, and existing multiple-pass joint aperture is fixing not
Can regulate, and in use sometimes for according to fluid pressure change joint pore size, to regulate pipeline pressure and flow velocity.
Summary of the invention
The technical problem to be solved is to provide a kind of pressure duct multiple-pass joint, can change the hole of shunting interface
Footpath size.
For solving above technical problem, the technical solution used in the present invention is: a kind of pressure duct multiple-pass joint, including interior
Pipe and outer tube, described outer tube sleeve is contained in outside inner tube and can rotate around inner tube, said inner tube is provided with some through holes, described outer tube
Upper and through hole relevant position is provided with some shunting interfaces, the aperture of described shunting interface and the equal diameters of through hole.
On described shunting interface, detachable end is installed.
It is provided with filter screen on described shunting interface.
The material of said inner tube and outer tube is carbon steel.
It is coated with anti-corrosion layer on said inner tube inwall and shunting interface inwall.
Described some through holes are arranged on the same cross section of inner tubal wall.
The beneficial effects of the present invention is: outer tube, when inner tube rotates, makes relative movement between shunting interface and through hole, when
When being completely superposed between shunting interface and through hole, the aperture of shunting interface is maximum, and misplacing between shunting interface and through hole connects
Time, the aperture of shunting interface reduces, when shunt misplace completely between interface and through hole time, shunting interface closes, by inner tube and
The rotation of outer tube achieves the aperture adjustment to shunting interface.
Therefore, a kind of pressure duct multiple-pass joint provided by the present invention, thus it is possible to vary the pore size of shunting interface, from
And reach to change velocity in pipes and pressure, the application being suitable in pressure duct.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross-sectional structure schematic diagram of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating the present invention
Technical scheme, and can not limit the scope of the invention with this.
A kind of pressure duct multiple-pass joint as illustrated in fig. 1 and 2, can change the pore size of shunting interface 4.
For solving above technical problem, the technical solution used in the present invention is: a kind of pressure duct multiple-pass joint, including interior
Pipe 1 and outer tube 2, described outer tube 2 is sleeved on outside inner tube 1 and can rotate around inner tube 1, said inner tube 1 is provided with some through holes 3,
Be provided with some shunting interfaces 4 on described outer tube 2 with through hole 3 relevant position, the aperture of described shunting interface 4 is straight with through hole 3
Footpath is equal.
On described shunting interface 4, detachable end is installed, when shunting interface 4 and need not connect distribution pipeline, can
Interface 4 is shunted by end cap seal.
It is provided with filter screen on described shunting interface 4, may filter that the impurity in fluid, prevent pipeline blockage, and filter screen position
At shunting interface 4, cleaning is convenient.
The material of said inner tube 1 and outer tube 2 is carbon steel.
It is coated with anti-corrosion layer on said inner tube 1 inwall and shunting interface 4 inwall, prevents flow-induced corrosion tube wall.
Described some through holes 3 are arranged on the same cross section of inner tube 1 wall.
The beneficial effects of the present invention is: outer tube 2, when inner tube 1 rotates, makes relative between shunting interface 4 with through hole 3 shifting
Dynamic, when shunt be completely superposed between interface 4 and through hole 3 time, the aperture of shunting interface 4 is maximum, when shunting interface 4 and through hole 3 it
Between dislocation when connecting, the aperture of shunting interface 4 reduces, when shunt misplace completely between interface 4 and through hole 3 time, shunting interface 4 closes
Close, achieve the aperture adjustment to shunting interface 4 by the rotation of inner tube 1 and outer tube 2.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
