For realizing this utility model purpose, the technical scheme of employing is: the wear resistance ball valve of a kind of automated cleaning sealing surface, bag
Including valve body, the spheroid being positioned at valve inner and the valve rod being positioned in the central axial direction of spheroid and fixing axle, its feature exists
In, it being provided with cleaning assemblies between described valve body and the gap of spheroid, cleaning assemblies is positioned in the relative direction of valve channel both sides
And match with the cambered surface of spheroid；On described valve rod and fixing axle, movable sleeve is provided with axle sleeve, and the end face of axle sleeve contacts with spheroid,
The same one end of the described cleaning assemblies being positioned at valve channel both sides is fixing with axle sleeve to be connected.
Further, described cleaning assemblies includes the support that the arc surface with spheroid matches, and support is near spherome surface
Side offer groove；Slide in described groove and be provided with the abrasive rubber bar matched with it；Described abrasive rubber bar
End face contacts with the surface of spheroid, is provided with multiple spring between abrasive rubber bar and support.
Further, one end of described spring is against the groove floor of support, and the other end is against on abrasive rubber bar.
Further, described fixing axle one end is fixing with valve seat to be connected, and the other end rotates with spheroid and arranges.
Employing this utility model has the advantage that
1, being provided with cleaning assemblies between sealing surface and the spheroid of valve body, cleaning assemblies matches with the cambered surface of spheroid and cleans
Assembly can be around the center axis thereof of spheroid, and when Open valve when, fluid enters into the inner space of valve body and spheroid, from
And fluid driven cleaning assemblies rotates, strike off the stuck foreign matter of spherome surface, it is achieved the automated cleaning of sealing surface；
2, utilize abrasive rubber bar that the surface of spheroid is cleaned, multiple owing to being provided with between abrasive rubber bar and support
Spring, to ensure that abrasive rubber bar is pushed against on the surface of spheroid all the time, makes the cleaning effect of cleaning assemblies more preferably and will not be because of
It is affected for the abrasion of abrasive rubber bar；
3, axle sleeve sheathed on valve rod and fixing axle, it is achieved cleaning assemblies rotates on the outer round surface of spheroid, it is achieved ball
The automated cleaning of valve, thus increase the service life.

Detailed description of the invention
Below by specific embodiment and combine accompanying drawing this utility model is described in further detail.
Fig. 1, Fig. 2 and Fig. 3 are the structural representations of the wear resistance ball valve of a kind of automated cleaning sealing surface that this utility model provides
Figure, including valve body 1, is positioned at the spheroid 2 within valve body 1 and the valve rod 3 being positioned in the central axial direction of spheroid 2 and fixing axle
4, it is characterised in that offer through hole on described spheroid 2, through hole forms circulation passage with the inside of valve body 1；On described valve rod 3
Connect with handles, be connected for clamping between valve rod 3 with spheroid 2, i.e. the rotation of valve rod 3 can drive the rotation of spheroid 2；Described valve body
Being provided with cleaning assemblies between 1 and the gap of spheroid 2, sealing of ball valve is mainly close by the laminating between sealing ring 9 and spheroid 2
Envelope, has certain gap between side and the spheroid 2 of valve body 1, and cleaning assemblies is positioned at the relative direction of valve body 1 passage both sides
On, i.e. it is positioned in the same diametric(al) of spheroid 2；Cleaning assemblies matches with the cambered surface of spheroid 2, i.e. ensures that cleaning assemblies is permissible
Along with axle sleeve 5 rotates around the central axial direction of spheroid 2 together；On described valve rod 3 and fixing axle 4, movable sleeve is provided with axle sleeve 5, axle
The end face of set 5 contacts with spheroid 2, and axle sleeve 5 can rotate on valve rod 3 and fixing axle 4, is positioned at valve body 1 passage both sides
The same one end of described cleaning assemblies and axle sleeve 5 is fixing to be connected, and makes the formation that is connected of cleaning assemblies and axle sleeve 5 be looped around spheroid
The annular ring of the outer round surface of 2.
Cleaning assemblies includes the support 6 matched with the arc surface of spheroid 2, and support 6 can be along the outer round surface of spheroid 2
Mobile, the impurity on spheroid 2 surface is purged, support 6 offers groove near the side on spheroid 2 surface；In described groove
Slide and be provided with the abrasive rubber bar 7 matched with it；The end face of described abrasive rubber bar 7 contacts with the surface of spheroid 2, resistance to
Being provided with multiple spring 8 between rubber milling bar 7 and support 6, multiple springs 8 make the surface that abrasive rubber bar 7 is against spheroid 2 all the time
On.
