Description
Technical field
This utility model is related to a kind of pressure duct multiple-pass joint of stabilized structure, belongs to high-pressure pipe member field.
Background technology
Multiple-pass joint is used for controlling the shunting of liquid or gas in pipe-line system, and existing multiple-pass joint aperture is fixing not
Can adjust, and in use sometimes for joint pore size is changed according to Fluid pressure, to adjust pipeline pressure and flow velocity.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pressure duct multiple-pass joint of stabilized structure, can change
The pore size of variation stream interface, and structure is simply firm.
For solving above technical problem, the technical solution adopted in the utility model is：A kind of pressure duct of stabilized structure
Multiple-pass joint, including inner and outer tubes, described outer tube is sleeved on outside inner tube and can rotate around inner tube, if being provided with said inner tube
Dry through hole, and some described through holes are arranged on the same cross section of inner tubal wall, and described outer tube is installed with through hole corresponding positions
It is equipped with some shunting interfaces, the aperture of described shunting interface and the equal diameters of through hole, said inner tube is stretched out to outer tube two ends, institute
State the snap ring that the oriented interior tube side in outer tube two ends extends, in said inner tube, corresponding positions are equipped with the draw-in groove embedding for snap ring.
It is provided with O-ring seal 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 utility model are：Outer tube around inner tube rotate when, make between shunting interface and through hole relative move
Dynamic, when being completely superposed between shunting interface and through hole, the aperture of shunting interface is maximum, misplaces between shunting interface and through hole
When connecting, the aperture of shunting interface reduces, and when misplacing completely between shunting interface and through hole, shunting interface is closed, by interior
The rotation of pipe and outer tube achieves the aperture adjustment to shunting interface.
Snap ring and draw-in groove achieve spacing in radial direction to inner and outer tubes, and the position preventing through hole and shunting interface is in rotation
There is radial deflection, thus ensureing the firm of structure it is ensured that shunting effect in turning.
Therefore, the pressure duct multiple-pass joint of a kind of stabilized structure provided by the utility model, thus it is possible to vary shunting connects
The pore size of mouth, thus reaching change velocity in pipes and pressure, structure is simply firm, is suitable for the application in pressure duct.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.Following examples are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
A kind of pressure duct multiple-pass joint of stabilized structure as shown in Figures 1 to 3, including inner tube 1 and outer tube 2, described outer
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 through hole 3 relevant position some shunting interfaces 4, institute
State 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 are equipped with the draw-in groove 6 embedding for snap ring 5.
It is provided with O-ring seal, described O-ring seal is arranged at the both sides of through hole 3 between said inner tube 1 and outer tube 2,
Prevent leakage crack between inner tube 1 and outer tube 2 for the fluid.
Between described snap ring 5 end and draw-in groove 6, ball 8 is installed, so that the sliding friction between inner tube 1 and outer tube 2 is changed into
Rolling friction, frictional force reduces, and outer tube 2 is more laborsaving when rotating.
On described shunting interface 4, detachable end is installed, when shunting interface 4 does not need to connect distribution pipeline, can
Shunt interface 4 with 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, prevent flow-induced corrosion tube wall.
The beneficial effects of the utility model are：Outer tube 2 around inner tube 1 rotate when, make phase between shunting interface 4 and through hole 3
To movement, when being completely superposed between shunting interface 4 and through hole 3, the aperture of shunting interface 4 is maximum, when shunting interface 4 and through hole
When between 3, dislocation connects, the aperture of shunting interface 4 reduces, and when misplacing completely between shunting interface 4 and through hole 3, shunts interface
4 closings, 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 spacing in radial direction to inner tube 1 and outer tube 2, to prevent through hole 3 and shunt interface 4 position
Put in rotation generation radial deflection, thus ensureing the firm of structure it is ensured that shunting effect.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement can also be made and deform, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
