Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
As Fig. 1, the adjustable location and installation instrument for valve rod locking nut shown in Fig. 2, comprise cylinder body 4, cylinder body 4 two ends arrange respectively interior hexagonal jack 7 and outer-hexagonal joint 1, described cylinder body 4 middle parts set gradually the collecting tank 8 of connection vertically, infusion hole 9 and pilot hole 10, described collecting tank 8 is positioned at the end of outer-hexagonal joint 1 place end, and the described collecting tank 8 tapered structures in cross section, described pilot hole 10 is communicated with interior hexagonal jack 7, the diameter of described pilot hole 10 is greater than the diameter of infusion hole 9, described cylinder body 4 peripheries are in axial direction also provided with the open slot 5 being communicated with pilot hole 10, described pilot hole 10 inside are provided with location jacking block 11, housing screw 6 is radially through being threaded with location jacking block 11 after open slot 5, described location jacking block 11 can move axially and can be fixed by housing screw 6 in pilot hole 10.
When the present embodiment uses, locking nut is screwed in to part in advance to valve rod, then coordinate with locking nut by interior hexagonal jack 7, hand-held cylinder body 4 rotary cylinder main bodys 4, are rotated and are driven locking nut to rotate by cylinder body 4, thereby by locking nut precession, pilot hole 10 is for guiding valve rod, in the time of precession valve rod upper end clamp by location jacking block 11 spacing, thereby reach the position location of locking nut, after setscrew nut is had good positioning, instrument is taken out; In the time taking out setscrew nut, also can adopt this instrument; The present embodiment is socketed handwheel on hex union 1 outside in the time of precession nut, and staff can hold hand wheel rotating cylinder body 4, time saving and energy saving, and handwheel can arbitrarily take off, and does not take up space; In the time of precession locking nut, as occurred the situations such as precession difficulty, jam, can in collecting tank 8, add lubricating fluid, lubricating fluid flows into valve rod and locking nut contact-making surface by infusion hole 9 and pilot hole 10, plays lubrication, reduces nut precession difficulty.
The present embodiment is in the time installing the locking nut of different model, due to the position location difference of locking nut, the length that stretch out valve rod upper end is also variant, for the nut that makes instrument can be used for multiple position location is installed, in the present embodiment, can locate the position of jacking block 11 in pilot hole 10 by adjustment, thereby limit the tip position of valve rod upper end, thereby can meet the nut installation of different position locations, practical.
