Abstract
A kind of valve rod selfsealings ball valve.Mainly solve existing ball valve Gland the problem of trouble is installed.It is characterized in that: described valve rod is provided with outside thread, described Gland is set on valve rod, and coordinates with the outside thread of valve rod by nut, is fixed Gland.Its advantage is that Gland is set in valve rod, and directly by a nut, is coordinated compressed Gland with valve rod, and not only structure is more simple compact, and easier for installation.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of valve rod selfsealings ball valve.
Background technique
Ball valve, spheroid is driven by valve rod, and around the valve that the axis of valve rod rotates, and is mainly used in blocking or the medium of the pipeline that links, and also can be used for adjusting and the control of fluid.
The structure of ball valve includes valve body, spheroid, seal ring valve rod, filler, Gland etc., and Gland need be fixedly connected with valve body by a plurality of bolts conventionally, and trouble is installed.
Model utility content
In order to overcome the deficiency of background technique, the utility model provides a kind of valve rod selfsealings ball valve, solves the problem that existing ball valve Gland is installed trouble.
The technological scheme that the utility model adopts: a kind of valve rod selfsealings ball valve, comprise valve body, spheroid and valve rod, described spheroid is arranged in valve body, and described valve rod is connected with spheroid through valve body; Between described valve body and valve rod, be provided with filler, described filler top is provided with the Gland that compresses filler, and described valve rod is provided with outside thread, and described Gland is set on valve rod, and coordinates with the outside thread of valve rod by nut, is fixed Gland.
On described Gland, be also integrally formed with a platform, described platform is provided with mounting hole.
Described mounting hole is provided with at least two and be uniformly distributed.
Described filler comprises filler and lower filler, and described upper filler is stainless steel material, and described lower filler is teflon.
Between described valve body and valve rod, be also provided with one deck seal ring.
The beneficial effects of the utility model are: adopt above scheme, Gland is set in valve rod, and directly by a nut, are coordinated compressed Gland with valve rod, and not only structure is more simple compact, and easier for installation.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
1-valve body in figure, 2-spheroid, 3-valve rod, filler under 4-, the upper filler of 5-, 6-Gland, 61-platform, 611-mounting hole, 7-nut, 8-seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of valve rod selfsealings ball valve, comprises valve body 1, spheroid 2 and valve rod 3, and described spheroid 2 is arranged in valve body 1, and described valve rod 3 is connected with spheroid 2 through valve body 1; Between described valve body 1 and valve rod 3, be provided with filler, described filler top is provided with the Gland 6 that compresses filler; Described valve rod 3 is provided with outside thread, and described Gland 6 is set on valve rod 3, and coordinates with the outside thread of valve rod 3 by nut 7, is fixed Gland 6;
Only by a nut 7, coordinated compressed Gland 6 with valve rod 3, not only structure is more simple compact, and easier for installation, and nut 7 coordinates with valve rod 3 in addition, makes Gland 6 stressed more concentrated, and effect is also better.
On described Gland 6, be also integrally formed with a platform 61, described platform 61 is provided with at least two and be uniformly distributed mounting hole 611, can be used for the convenient pneumatic or electric actuator of installing, and not only structure is more simple but also dismounting is convenient.
Described filler comprises filler 5 and lower filler 4, and described upper filler 5 is stainless steel material, and described lower filler 4 is teflon, between described valve body 1 and valve rod 3, be also provided with one deck seal ring 8 in addition, in simplified structure, further strengthened its sealability, prevent from revealing.
