Abstract
The utility model discloses a ball valve including a valve body (1), a sphere valve core (2), a valve seat (3), a valve cap (4), a valve rod (5), a seal filler (6), a nut (7), a handle (8) and a fixing nut (10). A valve rod neck (15) is formed on the sphere valve core (2); a clamping arm (14) matched with the valve rod neck (15) is arranged at the lower part of the valve rod (5), and a fixing valve rod (16) connected with the handle (8) is arranged at the upper part; a necking step (13) is arranged at the joint of the a fixing valve rod (16) and the valve rod (5); the nut (7) is a gland nut, and the gland thereof is matched with the necking step (13) of the valve rod (5). By adopting the structure, the ball valve eliminates the clearance between the valve rod and the sphere valve core, simplifies the structure and the installation process, and has the characteristics of simple and reasonable structure, convenient processing and assembly, stable and reliable performance, long service life and the like.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of easy to process, assemble simple ball valve.
Background technique
As everyone knows, ball valve is a kind of valve that switch is rapid, easy to operate, fluid resistance is little, simple in structure that has, and therefore is widely used in controlling the liquid conveying and the civilian plumbing of industry.Present ball valve generally comprises and interconnects valve body 1 and the valve gap 4 that is integral, be installed in valve seat 3, spheroid spool 2 in valve body 1 and the valve gap 4, the valve rod 5 that is connected with spheroid spool 2, the stuffing box packing 6 and the nut 7 that are used for valve rod 5 sealings, and be connected handle 8 on the valve rod 5 by set screw nut 10 and pad 9, valve rod 5 is provided with boss 51, valve body 1 is provided with the interior step 52 that matches with boss 51, spheroid spool 2 is provided with groove, and valve rod 5 is by being connected with spheroid spool 2 with flat bar that groove matches; During assembling, valve rod 5 is outwards installed in valve body 1, and boss 51 plays spacing valve rod 5, and stuffing box packing 6 and nut 7 play the effect of sealed valve stem 5.The deficiency of its existence: the one, need valve body 1 in step 52 in the processing, need processing boss 51 on the valve rod, the processing technology complexity, spillage of material is big, cost of production is high; The 2nd, between the boss 51 of the interior step 52 of valve body 1 and valve rod 5, there is bigger gap, the flat bar of valve rod 5 and the groove of spheroid spool 2 can not be mated fully, in use string is moving up and down easily for valve rod, the slit is increased produce and skid, cause ball valve normally not use; The 3rd, because valve rod 5 needs from inside to outside to install, cause complex structure, install inconvenient.
Summary of the invention
For overcoming existing ball valve above shortcomings part, the purpose of this utility model provide a kind of simple and reasonable, processing is easy to assembly, stable and reliable for performance, the ball valve of long service life.
The technological scheme that its technical problem that solves the utility model adopts, it comprises valve body, spheroid spool, valve seat, valve gap, valve rod, stuffing box packing, nut, handle, set screw nut, described spheroid spool is provided with the valve rod draw-in groove, stem lower portion is provided with the card arm that matches with the valve rod draw-in groove, top is provided with the fixedly valve rod that is connected with handle, fixedly the joint of valve rod and valve rod is provided with the reducing step, and described nut is a gland nut, and the reducing step of its gland and valve rod is complementary.
Further preferred version of the present utility model, described valve body is provided with the limiting stopper that matches with handle.
Further preferred version of the present utility model is arranged with taper knob on the described handle.
After adopting said structure, valve rod is 1 font structure, does not need to process boss, has reduced difficulty of processing, and production and processing is convenient, and material and processing charges are economized; Changed the mounting process of original ball valve, valve rod is installed from outside to inside, install, dismantle, keep in repair convenient, also eliminated simultaneously the gap between interior step 52 and the boss 51, can not producing up and down between valve rod and the spheroid spool, string moves, skids, thereby guaranteed product performance and quality, prolonged the working life of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of existing ball valve.
Embodiment
Shown in Figure 1, specific embodiments for a kind of ball valve of the utility model, it comprises valve body 1, spheroid spool 2, valve seat 3, valve gap 4, valve rod 5, stuffing box packing 6, nut 7, handle 8, pad 9, set screw nut 10, described spheroid spool 2 is provided with valve rod draw-in groove 15, no matter valve rod draw-in groove 15 what shape and structure do not influence installation, valve rod 5 bottoms are provided with the card arm 14 that matches with valve rod draw-in groove 15, top is provided with the fixedly valve rod 16 that is connected with handle 8, fixedly valve rod 16 is provided with reducing step 13 with the joint of valve rod 5, described nut 7 is a gland nut, the reducing step 13 of its gland and valve rod 5 is complementary, the effect of gland nut is the valve rod draw-in groove 15 close-fitting driving fits that make on valve rod 5 and card arm 14 and the spheroid spool 2, compress stuffing box packing 6 simultaneously, guarantee valve rod 5 sealings.Accurate in order to operate, described valve body 1 is provided with the limiting stopper 12 that matches with handle 8.Comfortable in order to operate, be arranged with taper knob 11 on the described handle 8.
Claims (3)
