Embodiment
Referring to figs. 1 through Fig. 3, the utility model ball valve embodiment is described further.
A kind of ball valve, comprise valve seat 1, valve seat 1 comprises the interface 11 of two connecting tubes, between two interfaces 11, be provided with the spherical open-shut device 2 of controlling fluid fluid opening/closing, on open-shut device 2, be connected with the valve rod 3 that extends valve seat 1, on valve rod 3, be socketed with knob 4, described one of them interface 11 inwall are provided with adjusting sleeve 5, between adjusting sleeve 5 and interface 11 inwalls, pass through screw-thread fit, adjusting sleeve 5 is provided with the seal ring 51 being sealed and matched with open-shut device 2, between described open-shut device 2 and valve rod 3, pass through spline fitted, described adjusting sleeve 5 is provided with driven wheel of differential 52 on the end face of open-shut device 2, described valve rod 3 is provided with the drive bevel gear 31 engaging with face gear in the axial activity of valve rod 3.
When between needs are to seal ring 51 and open-shut device 2, pressure is adjusted, can be by pressing knob 4 or pulling knob 4, embodiment preferably adopts valve rod 3 is pressed, make drive bevel gear 31 and engaging from mantle tooth in adjusting sleeve 5 on valve rod 3, now rotate knob 4 and just can adjust adjusting sleeve 5, simple and convenient; Between valve rod 3 and open-shut device 2, pass through spline fitted, in the time that drive bevel gear 31 engages with driven wheel of differential 52, open-shut device 2 can be followed valve rod 3 and be moved together, do not affect the adjustment of pressure between seal ring 51 and open-shut device 2, also can make to be connected separation between open-shut device 2 and valve rod 3, in the process of rotary valve rod 3, open-shut device 2 is motionless; The utility model preferably adopts bevel gear to realize the interlock between valve rod 3 and adjusting sleeve 5, because adopt bevel gear to have good guidance quality, occur in the process of axial motion at valve rod 3, interfere from being not easy to produce between mantle tooth and driving mantle tooth, certain gear-driven mode can be by other modes, for example friction driving, is replaced by the mode of clutch.
Because the adjustment of adjusting sleeve 5 is by valve rod 3 axial motions, realize the clutch between driven wheel of differential 52 and drive bevel gear 31 and realize, controlling in the process of open-shut device 2, if give valve rod 3 axial forces, easily change the axial position of valve rod 3, therefore misoperation-proof mechanism is set, make in the process of operation, relieved bold rotation knob 4, and without worrying after valve rod 3 axial motions, adjusting sleeve 5 is changed, and cause the pressure between seal ring 51 and open-shut device 2 to change.
Owing to adopting valve rod 3 is pressed to the adjustment realizing adjusting sleeve 5 in the utility model, by telescopic cover 6 is set, and locate by locating stud 7, now, valve rod 3 cannot be pressed, and has reached fool proof function, and when need to adjusting adjusting sleeve 5, pull up the locating stud 7 being plugged in positioning hole 61, just can adjust adjusting sleeve 5 by lower valve rod 3.
After valve rod 3 is pressed, on valve rod 3, separate with the spline in spline housing 21, valve rod 3 relatively open-shut device 2 rotates freely, and in the process of driving adjusting sleeve 5, open-shut device 2 meeting transfixions, have reduced operation adjustment and have overlapped the resistance in 5 processes.
In the process of operation adjustment cover 5, need to pin knob 4, and after having operated, valve rod 3 is upspring by Returnning spring 8 always, between valve rod 3 and open-shut device 2, interlock ensures the gap between knob 4 and telescopic cover 6 simultaneously.
The present embodiment is preferably arranged on Returnning spring 8 in telescopic cover 6, makes the structure of ball valve compacter, and the position of Returnning spring 8 also can be in valve seat 1 inside certainly.
