Abstract
The utility model relates to a ball valve, in particular to a ball core of the ball valve. According to the technical scheme, the ball core of the ball valve comprises a core body, wherein the core body is provided with a connection channel; openings through which the connection channel is communicated with the outside are formed in the positions, located at the two ends in the axial direction of the connection channel, of the core body; one opening of the core body comprises a semi-arc through hole and an adjusting through hole communicated with the semi-arc through hole; the cross section of the adjusting through hole is in a V shape; one end, connected with the semi-arc through hole, of the adjusting through hole is the big end; the other end of the adjusting through hole is the small end; the other opening of the core body is circular. By the adoption of the technical scheme, the ball core of the ball valve is simple in structure, impurities can be discharged, and flow is adjusted accurately.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of ball core of ball valve.
Background technique
Ball valve is that a kind of use is made open-shut device with the spheroid of manhole, and ball core rotates with valve rod, to realize the valve of switching motion.Traditional ball core is mainly circular body, on body, offer the connecting passage that runs through body, in use, after body rotates with valve rod, after the medium inlet passage and medium flow pass of connecting passage on it corresponding to ball valve body, ball valve is implemented to open, otherwise ball valve body is in closed condition.Because the connecting passage on body is manhole, in flow control process, connecting passage on it is difficult to flow to implement to regulate control, cannot accomplish to control accurately, and impurity in medium also can enter in connecting passage thereupon, impurity enters in the dead angle in connecting passage, cannot discharge, it is also more difficult to clean, and can cause the secondary pollution of medium.
Summary of the invention
The deficiency existing for prior art, the utility model provide a kind of Flow-rate adjustment precisely, can discharge the ball core of impurity, ball valve simple in structure.
For achieving the above object, the utility model provides following technological scheme: a kind of ball core of ball valve, include body, on body, offer connecting passage, the axial two ends place that body is positioned at connecting passage offers respectively the opening for connecting passage and extraneous conducting, it is characterized in that: one of them opening of described body includes semiarc shape through hole and the cross section that is communicated with semiarc shape through hole is the adjusting through hole of " V " font, one end that this adjusting through hole is connected with semiarc shape through hole is large end, the other end is small end, and another opening of described body is rounded.
Adopt technique scheme, one of them opening on body is set to be by semiarc shape through hole and cross section the special-shaped opening that the adjusting through hole of " V " font forms, after arranging like this, cross section is the adjusting through hole of " V " font can realize the adjusting to flow, be that medium is while being entered by the small end that regulates through hole, flow is less, while being entered by the large end that regulates through hole, flow is larger, can implement accurately to regulate to flow, and regulate through hole to be after " V " font, its inwall forms the cutting knife edge, can be by the impurity excision in medium, prevent that impurity from entering in the connecting passage of body.
The utility model is further set to: on the inwall of adjusting through hole, be evenly equipped with some flexuose projections.
Adopt technique scheme, setting can be shredded the impurity through in the medium of body like this, prevents from that impurity from entering in the connecting passage of body result in blockage or pollute.
The utility model is further set to: regulate the small end top of through hole and the arc of semiarc shape through hole to push up in same plane.
Adopt technique scheme, arrange like this and make the adjusting of flow more precisely even.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 is the utility model embodiment's schematic perspective view;
Fig. 2 is the utility model embodiment's structural representation;
Fig. 3 is the A-A generalized section of Fig. 2.
Embodiment
The ball core of a kind of ball valve as shown in Fig. 1-Fig. 3, include body 1, on body 1, offer connecting passage 11, the axial two ends place that body 1 is positioned at connecting passage 11 offers respectively the opening for connecting passage and extraneous conducting, one of them opening 12 of body 1 includes semiarc shape through hole 121 and the cross section that is communicated with semiarc shape through hole 121 is the adjusting through hole 122 of " V " font, one end that this adjusting through hole 122 is connected with semiarc shape through hole 121 is large end 1221, the other end is small end 1222, and another opening 13 of body 1 is rounded.In such scheme, one of them opening 12 on body 1 is set to be by semiarc shape through hole 121 and cross section the special-shaped opening that the adjusting through hole 122 of " V " font forms, after arranging like this, cross section is the adjusting through hole 122 of " V " font can realize the adjusting to flow, be that medium is while being entered by the small end 1222 that regulates through hole 122, flow is less, while being entered by the large end 1221 that regulates through hole 122, flow is larger, can implement accurately to regulate to flow, and regulate through hole 122 to be after " V " font, its inwall forms the cutting knife edge, can be by the impurity excision in medium, prevent that impurity from entering in the connecting passage 11 of body 1.It should be noted that, conventionally the opening 12 that semiarc shape through hole 121 and cross section are set are the adjusting through hole 122 of " V " font is set as to the medium entry port of body 1.
In the utility model embodiment,, prevent from that impurity from entering in the connecting passage 11 of body 1 result in blockage or pollute by the impurity chopping through in the medium of body 1 for further; On the inwall of adjusting through hole 122, be evenly equipped with some flexuose projections 123.
In order to make the adjusting of flow more precisely even, regulate small end 1222 tops of through hole 122 and the arc of semiarc shape through hole 121 to push up in same plane; Two chambers up and down in the same size that makes to regulate through hole 122 after arranging is like this more even when medium is passed through.
