Core 3 starts toward the starting stage moved left from right-most position, although the gap between guiding valve 3 and valve opening 13 adjacent face is very
Little, but but can accommodate more fluid media (medium) due to the existence of annular groove 36 so that fluid flowing and pressure oscillation are more
Stable.
As shown in Figure 6 and Figure 7, stationary ring 4 is a hollow shaft-like structure, and the center of axle is stationary ring through flow hole 44, stationary ring 4 one end
For controlling end, coaxial through described pilot hole 12;Control end stretches into spool cavity 33, described control through the oral area of spool cavity
Be provided with on end processed and the afterbody boss portion 42 that contact of hook 34, when guiding valve 3 under the effect of the first spring 6 to import 2
When direction moves axially, boss portion 42 and afterbody hook 34 contact with each other, and guiding valve 3 can haul stationary ring 4 together to the direction of import 2
Mobile;The other end of described stationary ring 4 is sealed end, is provided with the stationary ring flat seal portion corresponding with rotating shaft flat seal portion
41, the cylindrical of stationary ring 4 is provided with the second seal groove 45, be provided with in the second seal groove for pilot hole seal second
Sealing ring 102, the second sealing ring 102 can select O, and then, between stationary ring 4 and pilot hole 12 keep seal and can be along axle
To movement.
The rotating shaft flat seal portion 52 of rotating shaft 5 inserts in housing, and rotating shaft sealing portion 52 is coaxial with stationary ring flat seal portion 41
Being mounted opposite, axially arranged between stationary ring 4 and housing 1 have the second spring 7 being in compressive state, and the second spring 7 has handle all the time
Stationary ring 4 pushes the trend of rotating shaft 5 vertically to, moves when rotating shaft sealing portion 52 and stationary ring flat seal portion 41 can realize when fitting rotating
It is tightly connected;When stationary ring 4 moves to rotating shaft 5 direction rotating shaft sealing portion 52 and stationary ring flat seal portion 41 can gluing, sealing mutually,
When stationary ring 4 moves to guiding valve 3 direction, rotating shaft sealing portion 52 and stationary ring sealing 41 can disconnected from each other disengage.
It is provided with several outer rings in housing 1 and housing matches, the bearing 11 of the inner ring described rotating shaft 5 of support, bearing 11
Quantity can along with housing 1 length increase and increase, bearing 11 can ensure that shape is turned round in rotating shaft 5 high speed rotating when
State is stable, will not occur such as to shake, the phenomenon such as vibration, and then can ensure that the spin stabilization in rotating shaft sealing portion 52, at a high speed
Still can keep when needed with stationary ring flat seal portion 41 sealing during rotation, bearing 11 that quantity is the most be so that this
The ability keeping stable is the strongest, and then can bear the highest rotating speed.In the case of the rotating speed of rotating shaft 5 is higher, bearing 11 exists
Caloric value during high speed rotating is also bigger, therefore can offer some on the cylindrical of housing 1 for heat radiation
Heat radiation cannelure 10, improves the efficiency of heat radiation by the way of increasing cooling surface area.
Being provided with spline hole 43 on stationary ring 4, be provided with dog link 9 and be connected with housing 1 in spline hole 43, this is due to when quiet
When plane of a loop sealing 41 and rotating shaft sealing portion 52 gluing, sealing, owing to rotating shaft 5 is in rotary state, frictional force during laminating motion
Existence stationary ring 4 can be produced certain driving torque, when driving torque is less, the second sealing ring 102 on stationary ring 4 and leading
Frictional force between hole 12 can offset driving torque, but poor being easy to of reliability can cause stationary ring 4 to follow rotating shaft 5 turns
Dynamic, therefore, the structure that this spline hole 43 and dog link 9 coordinate in the case of ensureing that stationary ring 4 can freely complete other actions,
Limit the rotary freedom of stationary ring 4 so that stationary ring 4 under rotating shaft 5 is in high speed rotating state will not transfer, relatively reliable.
Offer leak 8 on housing 1, leak 8 is additionally provided with plug 14, due to rotating shaft sealing portion 52 and stationary ring plane
Sealing 41 be sealed into rotary dynamic seal, there may be trace seepage occur, the leak 8 of setting can be in time by seepage
Fluid media (medium) out is got rid of in time, and also has the function of leak detection, when extraneous dust is relatively big or be not intended to seal position with
Plug 14 can be used the when of extraneous directly contact to will leak out in the closure of hole 8.
Operation principle:
As in figure 2 it is shown, when not having fluid media (medium) to pass through in swivel joint, guiding valve 3 under the effect of the first spring 6, meeting
Moving to the rightmost side to import 2 direction vertically, at this moment, guiding valve 3 hauls stationary ring 4 also to import 2 direction by afterbody hook 34
Mobile, the stationary ring flat seal portion 41 on stationary ring 4 just with rotating shaft sealing portion 52 disengagement, it is to avoid dry friction.
As it is shown on figure 3, when the import 2 of swivel joint has been flowed into fluid media (medium) by the direction of hydraulic fluid port 15 when, just start,
Sealing owing to guiding valve sealing and hole sealing couple, fluid media (medium) cannot pass guiding valve 3, be blocked at import 2, gradually
At import 2, set up pressure, guiding valve 3 can be produced and the first spring 6 pressure opposite effect power, fluid media (medium) pressure at import 2
Power can be gradually increased, and then overcomes the effect of the power of the first spring 6, makes guiding valve 3 move to the direction of pilot hole 12, and afterbody is hung
Hook 34 and boss portion 42 disengage, and guiding valve 3 moves to rotating shaft 5 direction under the effect of the second spring 7, and rotating shaft sealing portion 52 is just with quiet
Plane of a loop sealing 41 is fitted, and then realizes rotary dynamic seal.
Presence or absence according to interior media switches laminating and the disengagement of sealing, is not having medium to cool down and lubrication and seal
The when of portion, sealing is separated, heating can be reduced, be substantially reduced the abrasion of sealing, prevent the generation of dry friction, greatly
Improve the service life of product, it is adaptable to inner-cooled machining center or drill gun etc. need the occasion of the highest rotary speed working.
