Further, the bottom of upper cap nut and lower nut is provided with the multiple prominent pawl be uniformly distributed circumferentially, and the multiple prominent pawl of upper cap nut is connected with the interlaced claw type that is formed as of the multiple prominent pawl of lower nut.
Further, multiple grooves of the prominent pawl of multiple accommodation lower nut are formed between the multiple prominent pawl of upper cap nut.
Further, the prominent pawl of the bottom of upper cap nut and lower nut is 3, and described groove is also 3.
Further, upper cap nut and lower nut are for being connected together.
Further, described upper cap nut or lower nut comprise the end with the first diameter and the footpath portion with Second bobbin diameter, and described first diameter is greater than Second bobbin diameter.
Further, the end of described upper cap nut and lower nut is hexagon.
Further, described upper cap nut with end upper, footpath portion under mounting type be arranged in handwheel; Described lower nut with footpath portion upper, end under mounting type be arranged in support.
The beneficial effects of the utility model are: by the split-type design of nut, improve the kind of drive, and add the gap between handwheel and valve body, make valve not easy to wear, easily open and close.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 2 to Fig. 4, below in conjunction with accompanying drawing, further specific descriptions are done to the utility model Outside screw stem rising through handwheel type gate valve.
A kind of Outside screw stem rising through handwheel type gate valve of the utility model, mainly comprises valve body 1, the lock lobe 2 be located in valve body 1, the valve rod 3 be flexibly connected with lock lobe 2.The top of valve body 1 is support 4, is connected with nut group in support 4.Support 4 is connected with valve rod by nut group, and support 4 is connected with handwheel 5 by nut group, leaves gap between support and handwheel.Nut group is inlayed and is connected in handwheel 5, and handwheel 5 is threaded with valve rod 3 by nut group.Nut group and support 4 and handwheel 5 coaxial, and be connected to support 4 and handwheel 5 is inner, be threaded with valve rod 3.
Described nut group adopts Split type structure, comprises upper cap nut 41 and lower nut 42.Upper cap nut 41 and lower nut 42 all comprise and have the end 43 of the first diameter and the footpath portion 44 of Second bobbin diameter, and the first diameter is greater than Second bobbin diameter, is horizontal transition between the first diameter and Second bobbin diameter.Upper cap nut 41 is coaxially connected in handwheel 5 by end 43, and end 43 upper footpath portion 44 under.Lower nut 42 is coaxially connected in support 4 by end 43, and footpath portion 44 is upper, end 43 under.
For removably connecting between upper cap nut 41 and lower nut 42, the transmission of lower nut is mainly relied on during handwheel opening/shutting valve, rotation hand wheel drives upper cap nut 41 to rotate, lower nut 42 rotates with upper cap nut 41 and is with ovable valve stem 3 to rotate, make valve rod 3 produce displacement on vertical direction, reach the object of opening/shutting valve.Because upper cap nut 41 and lower nut 42 do not produce the displacement of vertical direction when rotating, therefore remaining certain gap between handwheel and support, can not friction be produced each other when rotating.The frictionalwear between handwheel and support can be avoided by nut group, reduce and open and close difficulty.
Preferably, between upper cap nut 41 with lower nut 42 for claw type is connected.The prominent pawl 45 and groove 46 that are uniformly distributed circumferentially are arranged at the bottom of upper cap nut 41, the prominent pawl 45 relative with upper cap nut 41 and groove 46 are arranged at the bottom of lower nut 42, and the multiple prominent pawl of upper cap nut 41 is connected with the interlaced claw type that is formed as of the multiple prominent pawl of lower nut 42.Upper cap nut 41 is 3 with the prominent pawl 45 bottom lower nut 42, and groove 46 is also 3.Upper cap nut 41 is hexagon with the end 43 of lower nut 42, is conducive to fixing.Upper cap nut 41 is identical with the shape of lower nut 42, is convenient to processing and uses.
Preferably, between upper cap nut 41 and lower nut 42 for being connected together.Be uniformly distributed circumferentially engaging button bottom upper cap nut 41, bottom lower nut 42, be uniformly distributed circumferentially engagement groove accordingly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
