Description
Technical field
The present invention relates to a kind of eccentric half-ball valves.
Background technique
Currently, the eccentric half-ball valve provided in the market generally comprises valve body, valve deck, valve rod, valve seat, sphere and handwheel, ball
Body rotation is set in valve body, and valve rod is arranged on valve deck, and valve rod upper end and handwheel linkage, lower end and valve rod link, and valve seat is logical
It crosses bolt and is detachably set to valve body side, sphere is equipped with the spherical crown that can be against on valve seat, this eccentric half-ball valve disassembly process
Cumbersome, maintenance is got up more difficult, and the required precision of spherical crown is high, there are certain error when due to processing, once error
Larger or after a period of use, spherical crown and valve seat cannot form sealing well, in addition, above-mentioned eccentric half-ball valve is being closed
It is the easy gear of sundries (branch, textile bag etc.) in medium between spherical crown and valve seat, and then valve is caused not open and close normally.
Summary of the invention
In view of the deficiency of background technique, technical problem to be solved by the invention is to provide a kind of convenient disassemblies, leakproofness
Eccentric half-ball valve more preferable and with cutting function.
For this purpose, the present invention is to adopt the following technical scheme that realize:
Eccentric half-ball valve, including valve body, valve deck, valve rod, valve seat, sphere and handwheel, the sphere rotation is set in valve body, described
Valve rod is arranged on valve deck, and valve rod upper end and handwheel linkage, lower end and valve rod link, and the valve seat is detachably set by bolt
In valve body side, the sphere is equipped with the spherical crown that can be against on valve seat, it is characterized in that: the valve deck is located at valve body upper end, and
Valve deck outer is detachably connected by multiple studs and nut with valve body, and the spherical crown is detachably set to sphere by screw
On, there are gaps between spherical crown and sphere, and spherical crown is equipped with first waveform groove, and the sphere is equipped with alignment first waveform
Second contoured shaped recess of groove is equipped with bellows seal pad between the first waveform groove and the second contoured shaped recess.
Further, the valve seat inner end is equipped with multiple continuous first steps, and the spherical crown is equipped with can be with First
The second step of rank cooperation.
Further, the valve seat inner end is equipped with wavy bulge, and the spherical crown, which is equipped with, to be cooperated with wavy bulge
Groove.
After adopting the above technical scheme, valve deck is located at valve body upper end, and valve deck outer passes through multiple studs and nut
Be detachably connected with valve body, when maintenance the stud nut that need to only dismantle can remove valve deck, convenient disassembly and convenient for safeguarding, and
And spherical crown is detachably set on sphere by screw, there are gaps between spherical crown and sphere, and spherical crown is made to have certain activity empty
Between, for compensating spherical crown processing or the error generated, first waveform groove, the second contoured shaped recess and bellows seal pad being used for a long time
Cooperation makes the better tightness between spherical crown and sphere, in addition, the position that valve seat and spherical crown connect is step surface when closing valve
Or wavy surfaces, the sundries (branch, textile bag etc.) in medium can be cut off, guarantee the normal opening and closing of valve.
