Description
Technical field
The present invention relates to the pressure duct multiple-pass joint of a kind of stabilized structure, 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 the pressure duct multiple-pass joint of a kind of stabilized structure, can change point
The pore size of stream interface, and simple in construction is firm.
For solving above technical problem, the technical solution used in the present invention is: the pressure duct manifold of a kind of stabilized structure
Joint, including inner and outer tubes, described outer tube sleeve is contained in outside inner tube and can rotate around inner tube, said inner tube is provided with some logical
Hole, and some described through holes are arranged on the same cross section of inner tubal wall, and described outer tube is provided with through hole relevant position
Some shunting interfaces, the aperture of described shunting interface and the equal diameters of through hole, said inner tube stretches out to outer tube two ends, described outside
The snap ring that the oriented interior tube side in pipe two ends extends, in said inner tube, corresponding positions is equipped with the draw-in groove embedded for snap ring.
O-ring seal it is provided with between said inner tube and outer tube.
Between described snap ring end and draw-in groove, ball is installed.
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.
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.
Snap ring and draw-in groove achieve inner and outer tubes radially spacing, prevent the position of through hole and shunting interface in rotation
There is radial deflection in turning, thus ensure the firm of structure, it is ensured that shunting effect.
Therefore, the pressure duct multiple-pass joint of a kind of stabilized structure provided by the present invention, thus it is possible to vary shunting interface
Pore size, thus reach to change velocity in pipes and pressure, simple in construction consolidates, the application being suitable in pressure duct.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the vertical section structure schematic diagram of the present invention；
Fig. 3 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.
The pressure duct multiple-pass joint of a kind of stabilized structure as shown in Figures 1 to 3, including inner tube 1 and outer tube 2, described outside
Pipe 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, and some described through holes 3 set
It is placed on the same cross section of inner tube 1 wall, described outer tube 2 is provided with some shunting interfaces 4, institute with through hole 3 relevant position
Stating the aperture of shunting interface 4 and the equal diameters of through hole 3, said inner tube 1 is stretched out to outer tube 2 two ends, and described outer tube 2 two ends are oriented
The snap ring 5 that inner tube 1 side extends, in said inner tube 1, corresponding positions is equipped with the draw-in groove 6 embedded for snap ring 5.
Being provided with O-ring seal between said inner tube 1 and outer tube 2, described O-ring seal is arranged at the both sides of through hole 3,
Prevent fluid from leaking from the crack between inner tube 1 and outer tube 2.
Between described snap ring 5 end and draw-in groove 6, ball 8 is installed, makes the sliding friction between inner tube 1 and outer tube 2 become
Rolling friction, frictional force reduces, and outer tube 2 is the most laborsaving when rotating.
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.
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.
Snap ring 5 and draw-in groove 6 achieve inner tube 1 and outer tube 2 radially spacing, prevent through hole 3 and the position of shunting interface 4
Put generation radial deflection in rotation, thus ensure the firm of structure, it is ensured that shunting effect.
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.
