Description
Technical field
This utility model is related to adjustable pressure duct rotation multiple-pass joint, belongs to high-pressure pipe member field.
Background technology
Multiple-pass joint is used for controlling the shunting of liquid or gas, the shunt access of existing multiple-pass joint in pipe-line system
Immobilize, and generally require the quantity according to circumstances converting different shunt access or changing shunt access in use.
Utility model content
Technical problem to be solved in the utility model is to provide adjustable pressure duct to rotate multiple-pass joint, can change institute
The quantity of the shunting interface connected, and structure is simply firm.
For solving above technical problem, the technical solution adopted in the utility model is：A kind of adjustable pressure duct rotation is many
Pass joint, including inner and outer tubes, described outer tube is sleeved on outside inner tube and can rotate around inner tube, a certain cross section of said inner tube
On be provided with arc opening, the arc length of described arc opening is less than the half of said inner tube tube wall girth, and described outer tube sets
It is equipped with some shunting interfaces, described shunting interface and annular opening are arranged on same cross section, and shunts interface and be distributed in ring
In the range of shape opening, that is, annular opening can be connected with all shunting interfaces simultaneously, and said inner tube is stretched out to outer tube two ends,
The snap ring that the oriented interior tube side in described 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.
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 shunting interface quantity is 4.
The beneficial effects of the utility model are：Outer tube around inner tube rotate when, make shunting interface relative with arc opening move
Dynamic, when shunting interface is entirely located in the range of arc opening, all of shunting interface is all communicated with inner tube, when outer tube continues to turn
Dynamic, when part shunting interface goes to position disjunct with arc opening, then only remaining part shunting interface and inner tube
Communicate, when shunting interface and arc opening are completely misaligned, then shunting interface completely closes；Therefore this utility model is using interior
Pipe and outer tube rotate it is achieved that adjust shunt interface connect quantity.
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, adjustable pressure duct provided by the utility model rotates multiple-pass joint, thus it is possible to vary the company of shunting interface
Logical quantity, is easy to use, structure is simply firm, is suitable for the application in pressure duct.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is vertical section structure schematic diagram of the present utility model；
Fig. 3 is cross-sectional structure schematic diagram of the present utility model.
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 adjustable pressure duct rotation multiple-pass joint as shown in Figures 1 to 3, including inner tube 1 and outer tube 2, described outer tube 2
It is sleeved on outside inner tube 1 and can rotate around inner tube 1, a certain cross section of said inner tube 1 is provided with arc opening 3, described arc
The arc length of opening 3 is less than the half of said inner tube 1 tube wall girth, and described outer tube 2 is provided with some shunting interfaces 4, described
Shunting interface 4 is arranged on same cross section with annular opening, and shunting interface 4 is distributed in the range of annular opening, i.e. ring
Shape opening can be connected with all shunting interfaces 4 simultaneously, and said inner tube 1 is stretched out to outer tube 2 two ends, and described outer tube 2 two ends have
The snap ring 5 extending to inner tube 1 side, 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 7, described O-ring seal 7 is arranged at the two of through hole between said inner tube 1 and outer tube 2
Side, prevents 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.
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.
Described shunting interface 4 quantity is 4.
The beneficial effects of the utility model are：Outer tube 2 around inner tube 1 rotate when, make shunting interface 4 and arc opening 3 phase
