Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1, a kind of kelly cock, comprise body 1, snap ring 3, back-up ring 4, upper valve base 5, baffle ring 7, knob 9, shifting block 10, ball valve 11, lower valve base 12, folded spring 13, bearing 15, ball valve 11 both sides are provided with upper valve base 5, lower valve base 12, top is provided with shifting block 10, shifting block 10 is fixedly connected with knob 9, bearing 15 is fixed with between knob 9 and body 1, baffle ring 7 is provided with between upper valve base 5 and shifting block 10, snap ring 3 is provided with between upper valve base 5 end and body 1, back-up ring 4 is provided with in snap ring 3, seal ring is provided with between back-up ring 4 and snap ring 3, seal ring passing hole card 2 is fixed, folded spring 13 is provided with between lower valve base 12 and body 1.
Wherein, sealed by Sealing 1 between upper valve base 5 and body 1.Sealed by Sealing 2 14 between lower valve base 12 and body 1.Positioning ring 8 is provided with between shifting block 10 and baffle ring 7.
With special tool and cock spanner, stopcock knob 9 is rotated counterclockwise 90 °, by shifting block 10, drive ball valve 11 spool half-twist together, ball valve 11 through hole is consistent with body 1 through hole direction, stopcock is in open mode, with cock spanner, stopcock knob 9 is turned clockwise 90 °, by shifting block 10, drive ball valve 11 spool half-twist together, the through hole of ball valve 11 and valve hole perpendicular quadrature after complete switching in 90 °, upper lower valve base 12 and spool closely cooperate hydrophthalmia to block to be formed and seal.Stopcock is in closed condition.
Add knob 9 place bearing 15, reduce knob 9 switch moment, in emergency circumstances can quick closedown drilling rod valve, avoid knob 9 during use and rotate difficulty, structure is simple simultaneously, alleviates operator's operation easier.
The utility model is simple and compact for structure, convenient to use, reduces operation easier.Between knob and body, be fixed with bearing, facilitate the open and close of kelly cock, utilize disc spring to alleviate valve body vibration, increase the service life, improve the reliability of stopcock.Adopt seal ring, Sealing one, Sealing two to seal, increase the seal of stopcock.
