Abstract
The utility model discloses a kind of pressure duct rotates multiple-pass joint, including inner and outer tubes, described outer tube is sleeved on outside inner tube and can rotate around inner tube, it is provided with arc opening on a certain cross section of said inner tube, the arc length of described arc opening is less than the half of said inner tube tube wall girth, some shunting interfaces are provided with described outer tube, described shunting interface is arranged on same cross section with annular opening, and shunting interface is distributed in the range of annular opening, that is, annular opening can be connected with all shunting interfaces simultaneously.Therefore, pressure duct provided by the utility model rotates multiple-pass joint, thus it is possible to vary the connection quantity of shunting interface, is easy to use, is suitable for the application in pressure duct.
Description
Technical field
This utility model is related to 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 pressure duct rotation multiple-pass joint, can change and to be connected
The quantity of shunting interface.
For solving above technical problem, the technical solution adopted in the utility model is：A kind of pressure duct rotation to be connected
Head, including inner and outer tubes, described outer tube is sleeved on outside inner tube and can rotate around inner tube, and a certain cross section of said inner tube sets
It is equipped 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 is provided with
Some shunting interfaces, described shunting interface and annular opening are arranged on same cross section, and shunting interface is distributed in annular and opens
In the range of mouthful, that is, annular opening can be connected with all shunting interfaces simultaneously.
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.
Described some shunting interfaces are set to different apertures.
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.
Therefore, pressure duct provided by the utility model rotates multiple-pass joint, thus it is possible to vary the Betti number of shunting interface
Amount, is easy to use, is suitable for the application in pressure duct.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 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 pressure duct rotation multiple-pass joint as illustrated in fig. 1 and 2, including inner tube 1 and outer tube 2, described outer tube 2 is set with
Rotate can outward and around inner tube 1 in inner tube 1, a certain cross section of said inner tube 1 is provided with arc opening 3, described arc opening 3
Arc length be less than the half of said inner tube 1 tube wall girth, described outer tube 2 is provided with some shunting interfaces 4, described shunting connects
Mouth 4 and annular opening are arranged on same cross section, and shunting interface 4 is distributed in the range of annular opening, i.e. annular opening
Can be connected with all shunting interfaces 4 simultaneously.
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.
Described some shunting interfaces 4 are set to different apertures, can connect the shunting interface 4 of different pore size as needed,
Reach the effect changing partial flow rate and pressure.
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
To movement, when shunting interface 4 is entirely located in the range of arc opening 3, all of shunting interface 4 is all communicated with inner tube 1, when outer
Pipe 2 is rotated further, when part shunting interface 4 goes to arc opening 3 disjunct position, then only remaining part shunting
Interface 4 is communicated with inner tube 1, and when shunting interface 4 and arc opening 3 are completely misaligned, then shunting connects excuse and completely closes；Therefore
This utility model utilizes the rotating it is achieved that adjust shunting interface 4 connects quantity of inner tube 1 and outer tube 2.
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.
