Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protect the present invention
The restriction of scope.
Novel shaft symmetry plug vector spray of the present invention is described in further details by 1 to Fig. 4 below in conjunction with the accompanying drawings.
The invention provides a kind of Novel shaft symmetry plug vector spray, including cylinder 1, support plate 2, plug cone leading portion 3, plug cone
Back segment 4, mounting seat 5, pressurized strut 6, lever 7 and connecting rod 8.
Cylinder 1 is one, and leading portion is column type flat segments, and back segment is converging portion.
Plug cone leading portion 3 is one, is positioned at described cylinder 1 internal, and the interior profile of the rear end of described plug cone leading portion 3 is sphere.
Plug cone back segment 4 is one, front end have with described plug cone leading portion 3 rear end in outside profile shapes and sizes match
Profile, and constitute spherical pair by the interior profile of described outer mold surface with described plug cone leading portion 3.
Support plate 2 quantity is 3, uniform along jet pipe circumference；Support plate 2 one end is welded with described cylinder 1, the other end and described plug
Cone leading portion 3 welds；And described support plate 2 is hollow structure, for the inner chamber of described plug cone leading portion 3 is connected outside described cylinder 1
Logical.
Pressurized strut 6 one end is hinged on the position on described cylinder 1 outer ring surface with described support plate 2；Specifically, Ke Yi
Having one mounting seat 5 of position welding of described support plate 2 on described cylinder 1 outer ring surface, one end of described pressurized strut 6 is hinged on
In mounting seat 5；Equally, mounting seat 5 quantity is 3, uniform along jet pipe circumference.
Lever 7 is positioned in the inner chamber of support plate 2, and middle part is hinged on described support plate 2, another of one end and described pressurized strut 6
Hold hinged；In the present embodiment, lever 7 quantity is 3, and each support plate 2 is internal arranges one.Further, offer in the middle part of lever 7
Porose B, is hinged on support plate 2 by hole B.
Connecting rod 8 is positioned in the inner chamber of described plug cone leading portion 3, and one end is hinged with the other end of described lever 7, the other end and institute
The one end of the close described plug cone leading portion 3 stating plug cone back segment 4 is hinged.Equally, lever 7 quantity is 3.Furthermore it is possible to described
One end of the close described plug cone leading portion 3 of plug cone back segment 4 is provided with bearing A, and described connecting rod 8 other end is hinged on described bearing A
On；The position of bearing A can carry out the setting being suitable for as required, preferably at the edge of plug cone back segment 4 radial direction in the present embodiment
Place, is driven plug cone back segment 4 leggiero with more convenient.
As a example by above-mentioned 3 pressurized struts 6, when Novel shaft symmetry plug vector spray carries out vector regulation, first it is cylinder
Pressurized strut 6 start on body 1 outer ring surface, each concrete pressurized strut 6 is elongation or shrinks and can carry out according to regulation needs
The control being suitable for, two pressurized struts 6 that such as can control to be positioned at (relative) top extend, and are positioned at a start of bottom
Cylinder 6 shrinks, now through the lever 7 being respectively connected and the effect of connecting rod 8 so that before being subject to away from plug cone bottom plug cone back segment 4
The direction thrust of section 3, and fill in cone back segment 4 top and be subject to the direction force pulling force towards plug cone leading portion 3, so that plug cone back segment 4
Rotate (with reference to the view direction shown in Fig. 1) in the counterclockwise direction, thus realize the vector regulation of jet pipe；The regulation in other directions
Principle is similar to, and repeats the most one by one.
Certainly, in other alternatives, when carrying out vector regulation, above-mentioned 3 pressurized struts 6 even have only to wherein
One carries out start, just can realize, and here is omitted.
The Novel shaft symmetry plug vector spray of the present invention, simple and reliable for structure, can effectively realize throat area regulation,
Meet the needs of electromotor different operating state.
