For technical staff, above-mentioned term concrete meaning in the present invention can be understood with concrete condition.Additionally, in description of the invention
In, except as otherwise noted, " multiple " are meant that two or more.
In flow chart or at this, any process described otherwise above or method description are construed as, and expression includes
One or more is for realizing the module of code, fragment or the portion of the executable instruction of the step of specific logical function or process
Point, and the scope of the preferred embodiment of the present invention includes other realization, wherein can not by shown or discuss suitable
Sequence, including according to involved function by basic mode simultaneously or in the opposite order, performs function, and this should be by the present invention
Embodiment person of ordinary skill in the field understood.
As it is shown in figure 1, the invention provides a kind of high-pressure rotation compensator, including trocar sheath 1 and inner tube 2, said inner tube 2
Left end insert trocar sheath 1 endoporus in, said inner tube 2 can rotate axially with respect to trocar sheath 1, the outer wall of said inner tube 2
It is tightly connected with the inner hole wall of described trocar sheath 1, on the outer wall of said inner tube 2, at nearly left side, is provided with radially protruding platform
Rank 3；On the inner hole wall of described trocar sheath 1, it is provided with radially protruding baffle ring 4 on the right side of described step 3；As in figure 2 it is shown, institute
Stating and be provided with wear ring 5 between step 3 and baffle ring 4, the shape of cross section of described wear ring 5 is circular, and described wear ring 5 pastes respectively
Close right flank and the left surface of baffle ring 4 of step 3.
Operationally, the inner chamber of trocar sheath 1 and inner tube 2 has been filled with working media, described overcoat to high-pressure rotation compensator
Pipe 1 and inner tube 2 are tightly connected, it is ensured that the medium of inner chamber will not leak into the external world.Pressure is there is, due to platform in working media
The difference in areas of the left and right sides, rank 3, the pressure in working media can by formed on step 3 to the right make a concerted effort wear ring 5 is pressed
Tight on the left surface of baffle ring 4, wear ring 5 can ensure that in the inner tube 2 relative and rotary course of trocar sheath 1 after compaction have
There is less frictional force, it is ensured that contact friction can persistently be carried out.
The material of described wear ring 5 is red copper, the material of red copper so that wear ring 5 has good anti-wear performance,
The friction pair formed is possible to prevent wear ring 5 to produce the phenomenon of adhesive wear when contacting friction with inner tube 2 and trocar sheath 1.
Between outer wall and the inner hole wall of trocar sheath 1 of said inner tube 2, it is provided with face seal 6, face seal 6 on the right side of described baffle ring 4
Can ensure that inner tube 2 rotates the most vertically relative to trocar sheath 1, can ensure that again inner tube 2 and the sealing of trocar sheath 1 simultaneously
Connect.
Also including that flange 8, described flange 8 are annular, described flange 8 is arranged on the right side of trocar sheath 1 and is set in described
On the outer wall of inner tube 2, the left surface of described flange 8 and the right flank of described trocar sheath 1 have gap；The left side of described flange 8
Face is provided with the boss 9 of annular protruding vertically, the cylindrical of described boss 9 and the inner hole wall matched in clearance of described trocar sheath 1,
The left end of described boss 9 stretches in the endoporus of trocar sheath 1 and face seal 6 is pressed on the right flank of described baffle ring 4, described
Flange 8 and trocar sheath 1 are connected by clamp device 7.
Flange 8 can cover the right ports port part of trocar sheath 1, has certain dirt exclusion capabilities, also limit simultaneously
Face seal 6 degree of freedom vertically, prevented because of showing that the swivel becket face seal 6 of inner tube 2 is run out of from the endoporus of trocar sheath 1
As；Face seal 6 can be pressed on baffle ring 4 by boss 9 simultaneously, improves the sealing effectiveness of face seal 6；Work as face seal
There is abrasion in the sealing surface of 6, when sealing effectiveness declines, can be by adjusting clamp device 7, and hold-down ring face seal 6 is extensive again
Complex torus seals the sealing function of 6.
The clamp device 7 being arranged on trocar sheath 1 by flange 8 can be the cooperation of screw bolt and nut, when ring packing 6 goes out
Now by screwing screw bolt and nut, flange 8 can be pressed in ring packing 6 again after abrasion, and screw bolt and nut is can
Dismounting connect, mount and dismount the most very convenient simply.
Described face seal 6 is packing seal, and gland sealed sealing effectiveness is reliable, product technology maturation and sealing member
Cost is relatively low.The left side of nearly trocar sheath 1, the tube wall vertical sectional shape of described trocar sheath 1 is the cone gradually tapered up from left to right
Set shape.
The tube wall of this tapered sleeve shape constitutes a structure closed up at the left end of trocar sheath 1, improves interior media flowing
Fluid state, this closing in simultaneously also limit the degree of freedom that inner tube 2 moves axially to the left, it is to avoid inner tube 2 too much to
Left slip thus the phenomenon that skidded off by left end.Meanwhile, this closing-in structure is integral die structure, suppresses after inner tube 2 assembles
Molding so that whole trocar sheath 1 does not has weld seam, substantially increases structural strength and the sealing property of trocar sheath 1, also reduces simultaneously
Manufacturing cost.
Described trocar sheath 1 and inner tube 2 are solid forging structure, parts instead of routine such as structures such as welding, tool
There is the highest structural strength, add product reliability.
