For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of ball valve with valve opening and closing monitoring position; Comprise valve body, valve rod and spool; Be provided with the valve seat that cooperates with spool with the intake-outlet joint in the valve rod mounting hole and the entery and delivery port that are provided with valve pocket in the valve body and are communicated with, valve pocket with valve pocket; Said stem shaft is passed the valve rod mounting hole to an end and is stretched in the valve pocket and be connected with spool; The axial the other end stretches out its end of valve body operating grip is installed; Be provided with the seal arrangement of realizing valve rod and valve seal in the valve rod mounting hole; Described stem shaft is equipped with signal-transmitting machine on an end that stretches out valve body, said signal-transmitting machine comprises the sender piece that is sheathed on the valve rod and induction sender piece position and is in the position limit switch of generation valve state signal under full cut-off and the full-gear at valve.
Through adopting technique scheme, the sender piece rotates with valve rod, and when valve was in full cut-off and full-gear, position limit switch was corresponding with sender piece position, produces valve state signal; Avoid operator not operate under complete opening or the situation of closing, cause security incident at valve.
The utility model further is set to: described sender piece is the eccentric eccentric wheel that is installed on the valve rod and rotates with valve rod, valve opening or when closing, sender piece heavy wall one side is corresponding with the position limit switch position.
Through adopting technique scheme, when sender piece heavy wall one side and limit switch at once, limit switch sends signal and flies remote service end (thereby the indication valve is in unlatching or closed condition provides protection to belonging to pipe-line system); Simultaneously, the monitoring of valve opening and shutdown signal is simple, convenient and reliable.
The utility model further is set to: described seal arrangement includes pad, tetrafluoro filler, filler gland and hold-down grid; Said valve rod mounting hole is a step hole; The big nose end of valve rod mounting hole is the packing cavity away from valve pocket; Packing cavity sets gradually pad, tetrafluoro filler and filler gland from the bottom to the top, and said filler gland one end stretches into and compresses the tetrafluoro filler in the valve rod mounting hole, and the other end and hold-down grid are conflicted; Said hold-down grid is set on the valve rod, and is locked at formation being pressed in the packing cavity the filler gland on the valve body.
Through adopting technique scheme, adopt wear-resisting tetrafluoro packing seal, sealability is reliable, long service life.
Below in conjunction with accompanying drawing the utility model is further described.
