Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of single piece type floating ball valve, its processing, easy to assembly, precision is high.
The technical solution of the utility model: a kind of single piece type floating ball valve, include valve body, valve rod, described valve body is provided with valve pocket, flow channel, flow pass, described flow channel, flow pass and valve pocket conducting, in described valve pocket, be provided with spool, valve seat, described valve rod is provided with step, on valve body, corresponding flow channel or flow pass position have expanded outwardly pilot hole, in pilot hole, be provided with valve seat gland, valve seat gland is pressed on valve seat, it is characterized in that: described valve body upper end is provided with the through hole with valve pocket conducting, in described through hole, be provided with stem bearing, described stem bearing is provided with mounting hole, described valve rod one end extends in valve pocket and is linked with spool through mounting hole, conflict in step on described valve rod and stem bearing lower end, described stem bearing is fixedly connected with valve body.
Adopt technique scheme, during assembling, first spool, valve seat are packed in valve pocket from pilot hole, then, after valve rod and stem bearing are assembled, be installed on valve body, and conflict in step on valve rod and stem bearing lower end, need in valve pocket, not process like this shoulder rank, therefore, the single piece type floating ball valve of this structure, its processing, easy to assembly, precision is high.
Further setting of the present utility model: described valve seat gland coordinates with valve body screw thread, is provided with elastic seal ring between described valve seat gland and valve seat.
Adopt above-mentioned further setting, the elastic seal ring of setting can guarantee the sealing between valve seat gland and valve seat; The pretightening force between regulating valve seat gland regulating valve seat and spool can be passed through again, thereby the torque force of valve rod can be reduced.
Further setting more of the present utility model: be provided with seal ring between described stem bearing and valve body.
Adopt above-mentioned further setting again, the seal ring of setting, makes good airproof performance between stem bearing and valve body.
Further setting more of the present utility model: be also provided with one on the other two seal rings between described valve rod and mounting hole, on described valve rod, corresponding seal ring position is provided with annular groove, and described seal ring is arranged in annular groove.
Adopt above-mentioned further setting again, two seal rings that arrange one on the other by arranging, can prevent that medium from leaking, and also can prevent that introduced contaminants from entering in valve pocket, makes the better tightness of valve.
