Abstract
The invention discloses a kind of floating ball valve, including valve body, sphere and connector, connector and valve body form the lumen for being used for placing sphere, are clearance fit between the cavity wall of lumen and the outer surface of sphere, gap size is 0.5mm 1mm, and the outer surface of above-mentioned lumen and sphere uses mirror surface treatment.Beneficial effects of the present invention are：It can reduce impurity in ball valve and accumulate.
Description
Technical field
The present invention relates to ball valve technical field, and in particular to a kind of floating ball valve.
Background technology
Floating ball valve is simple in structure, good seal performance, is widely used in the control system of the industries such as oil, natural gas.
But in the operating modes such as dichloromethane, starchy food product, medicine, fermentation, often occur that sphere is stained with many impurity,
Lumen piles with impurity, and valve torque is increasingly heavier, to the end must not be not parking, reprocesses valve.
The content of the invention
It is an object of the invention to provide a kind of floating ball valve, it can reduce impurity in ball valve and accumulate.
To achieve the above object, the present invention provides following technical solution：
A kind of floating ball valve, including valve body, sphere and connector, connector and valve body form the lumen for being used for placing sphere, in
It is clearance fit between the cavity wall of chamber and the outer surface of sphere, gap size 0.5mm-1mm, the appearance of above-mentioned lumen and sphere
Face uses mirror surface treatment.
Preferably, when ball valve is opened, the inner wall for the intermediate channel that valve body, sphere and connector are formed uses mirror surface treatment.
The present invention operation principle be：
Gap size is 0.5mm-1mm between the cavity wall of lumen and the outer surface of sphere, and the medium of bulky grain will not enter cavity,
It can be washed away by medium along passage, and the passage of spherome surface and sphere uses mirror surface treatment, it is possible to reduce short grained heap
Product；So as to reduce moment of torsion, while reduce the cost of shutdown maintenance in operating conditions.
Beneficial effects of the present invention are：It can reduce impurity in ball valve and accumulate.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is further described.Following embodiments are only
For clearly illustrating technical scheme, and it is not intended to limit the protection scope of the present invention and limits the scope of the invention.
The technical solution that the present invention is embodied is：
As shown in Figure 1,
A kind of floating ball valve, including valve seat 4, valve body 1, sphere 3 and connector 2, connector 2 and valve body 1, which are formed, to be used to place ball
The lumen of body 3, is clearance fit between the cavity wall of lumen and the outer surface of sphere 3, gap size 0.5mm-1mm, in above-mentioned
The outer surface of chamber and sphere 3 uses mirror surface treatment.
Preferably, when ball valve is opened, the inner wall for the intermediate channel that valve body 1, sphere 3 and connector 2 are formed uses mirror
Reason.
The present invention operation principle be：
Gap size is 0.5mm-1mm between the cavity wall of lumen and the outer surface of sphere 3, and the medium of bulky grain will not enter chamber
Body, can be washed away by medium along passage, and the passage of 3 surface of sphere and sphere 3 uses mirror surface treatment, it is possible to reduce little particle
Accumulation；So as to reduce moment of torsion, while reduce the cost of shutdown maintenance in operating conditions.
Beneficial effects of the present invention are：It can reduce impurity in ball valve and accumulate.
The above is only the preferred embodiment of the present invention, it is noted that is come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
