Abstract
The utility model relates to a ball-valve valve rod with a ball core, which comprises a valve rod body, wherein the valve rod body is provided with the ball core. The ball core and the valve rod body are integrally formed, and the ball core is provided with a connecting channel for media to flow through. By adopting the technical scheme, the ball-valve valve rod with the ball core can reduce production cost and can guarantee that the ball core rotates reliably.
Description
Technical field
The utility model relates to valve field, particularly a kind of ball valve valve rod that has the ball core.
Background technique
At present, existing ball valve generally comprises the valve body that is provided with valve pocket; Be provided with valve rod, ball core in the valve pocket; Valve body is provided with medium flow channel, medium flow pass, medium flow channel, medium flow pass all with the valve pocket conducting, the ball core is provided with connecting passage; Valve rod is used for drive ball core rotation, thereby the ending of control connection passage and medium flow channel, medium flow pass, unlatching that on state is promptly controlled ball valve, closes.Wherein, ball core and valve rod are linked through locating stud.
But the ball valve of this structure makes processed complex, thereby has increased cost of production, and valve rod drives the rotation of ball core through locating stud, and this kind of drive is unstable.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of ball valve valve rod that has the ball core, can reduce production costs, and can guarantee that the rotation of ball core is reliable.
The technological scheme of the utility model: a kind of ball valve valve rod that has the ball core, include valve stem body, on described valve stem body, be provided with the ball core, described ball core and valve stem body are one-body molded, and described ball core is provided with the connecting passage that supplies MEDIA FLOW to cross.
Adopt technique scheme; Through described valve stem body and described ball core are wholely set; Do not need locating stud to realize being connected of valve stem body and ball core like this; Only need direct actuate valve stem body can realize the rotation of ball core, thereby reduced cost of production, and can guarantee that the rotation of ball core is reliable.
The further setting of the utility model: described connecting passage and axially vertical setting of valve stem body.
Adopt above-mentioned further setting, because the general average level setting of medium flow channel, medium flow pass of ball valve, and valve pocket generally vertically is provided with, and therefore, described connecting passage and axially vertical setting of valve stem body, adaptability is stronger.
Further being provided with again of the utility model: the face that described ball core is positioned at the connecting passage two ends is planar end surface.
Adopt above-mentioned further setting again, the face that the ball core is positioned at the connecting passage two ends all is set to planar end surface, can save material, can make things convenient for sealing setting between ball core and the valve body again.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
As shown in Figure 1, a kind of ball valve valve rod that has the ball core includes valve stem body 1, on described valve stem body 1, is provided with ball core 2, and described ball core 2 is one-body molded with valve stem body 1, and described ball core 2 is provided with the connecting passage 21 that supplies MEDIA FLOW to cross.When mounted, only need this ball valve valve rod that has the ball core directly is installed in the inner chamber of valve body, then valve stem body is connected with drive unit, drive unit is used for actuate valve stem body 1 and rotates.
In the utility model specific embodiment, described connecting passage 21 and valve stem body 1 axial vertical setting.
In the utility model specific embodiment, the face that described ball core 2 is positioned at the connecting passage two ends is planar end surface 22.
Claims (3)
