Description
Technical field
The utility model is related to a kind of valve, and in particular to a kind of improvement ball valve.
Background technology
Ball valve is driven by valve rod for spheroid, and the valve that rotates of axis around valve rod.It is mainly used in blocking or connects
Medium in siphunculus road, it can also be used to the regulation and control of fluid.
Existing ball-valve valve rod is rotated when valve is opened and closed, and the sealing at this is even more important, and general sealing is by close
The built-in encapsulant of sealing groove, encapsulant typically from rubber blanket or polytetrafluoroethylene (PTFE) material, the material easily corrosion and damage, or
Deformation, affects the sealing sealed on valve, can affect valve service life to using bringing inconvenience.
Utility model content
In order to overcome the shortcomings of that background technology, the utility model provide a kind of improvement ball valve, mainly solve existing ball
The sealing effectiveness difference of valve valve rod and valve gap and the troublesome problem of sealing structure repair and replacement, the improvement ball-valve structure letter reasonable in design
Single, by valve gap the week side of boss providing holes, replaceable upper encapsulant and sealing pretensioning operation is carried out to upper encapsulant, it is ensured that
The upper sealing effectiveness of valve, extends the service life of valve.
The technical scheme adopted by the utility model is：A kind of improvement ball valve, including valve body, be provided with the valve body by
Valve rod drives the spheroid of rotation, the spheroid both sides to be provided with the valve seat coordinated with ball seal, above the valve body in connection
Valve body, the valve stem tip connect actuating arm through upper valve body, are provided with stuffing box, the upper valve between the upper valve body and valve rod
Body the week side of boss is provided with the hole connected with stuffing box, and hole is provided with threaded cap, is placed with ball in stuffing box, and valve rod is placed at stuffing box section
Appearance bread is equipped with open loop structure, and stuffing box bottom sets sealing gasket, stuffing box upper end bonding pad gland.
Ball of the stuffing box on the open loop structure and upper valve body built with tight distribution, ball adopt quality of rubber materials.
The hole is uniformly distributed on upper valve body, and is connected with stuffing box, and hole is at least provided with three.
The beneficial effects of the utility model are：Due to taking above-mentioned technical proposal, existing ball-valve valve rod is effectively improved
And sealing structure repair and replacement troublesome problem poor with the sealing effectiveness of valve gap, the improvement ball-valve structure are reasonable in design simple, lead to
Cross in valve gap the week side of boss providing holes, replaceable upper encapsulant and sealing pretensioning operation is carried out to upper encapsulant, it is ensured that valve
Upper sealing effectiveness, extends the service life of valve.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of improvement ball valve, including valve body 1, is provided with the valve body 1 and is driven by valve rod 2
The spheroid 3 of rotation, 3 both sides of the spheroid are provided with and are sealed the valve seat 4 for coordinating with spheroid 3, connect upper valve body above the valve body 1
5,2 top of the valve rod connects actuating arm 6 through upper valve body 5, is provided with stuffing box 7 between the upper valve body 5 and valve rod 2, described
5 the week side of boss of upper valve body is provided with the hole 9 connected with stuffing box 7, and hole 9 is provided with threaded cap 10, is placed with ball 11, valve rod 2 in stuffing box 7
It is placed in appearance bread at 7 sections of stuffing box and is equipped with open loop structure 12,7 bottom of stuffing box sets sealing gasket 8, and the connection of 7 upper end of stuffing box is filled out
Material gland 13.
Ball 11 of the stuffing box 7 on the open loop structure 12 and upper valve body 5 built with tight distribution, ball 11 adopt rubber
Glue material matter.
The hole 9 is uniformly distributed on upper valve body 5, and is connected with stuffing box, and at least provided with three, screw thread changes 10 and leads in hole 9
Via 9 is screwed to 2 direction of valve rod, carries out pretension to the ball 11 in stuffing box 7, when the sealing of upper sealing structure loosens, is passed through
Adjust threaded cap 10 to be adjusted, it is also possible to which threaded cap 10 is screwed out, and is changed ball 11 by hole 9, to ensure the close of valve
Sealing property, extends the service life of valve, while open loop structure 12 can also be changed by hole 9, it is preferable that open loop structure 12
From polytetrafluoroethylene (PTFE) material.
The utility model effectively improves the sealing effectiveness difference of existing ball-valve valve rod and valve gap and sealing structure changes dimension
Repair troublesome problem, the ball-valve structure is reasonable in design simple, by valve gap the week side of boss providing holes, replaceable upper encapsulant and
Sealing pretensioning operation is carried out to upper encapsulant, it is ensured that the upper sealing effectiveness of valve, extend the service life of valve.Every technical staff
Notice：Although the utility model is described according to above-mentioned specific embodiment, invention thought of the present utility model is simultaneously
This utility model is not limited only to, the repacking of any utilization inventive concept will be all included in this patent scope of patent protection.
