In above-mentioned integral whole-through diameter ball valve, be provided with stuffing box packing between described valve rod and the gland.Such structure can strengthen the sealing between valve rod and the gland.
In above-mentioned integral whole-through diameter ball valve, the end of described regulating valve seat has the seal ring seat of breach in the form of a ring, and seal ring is housed in the seal ring seat, and seal ring contacts with above-mentioned spool.
Owing between regulating valve seat and spool, have seal ring, so just can increase the sealing between regulating valve seat and the spool.Simultaneously, because the seal ring seat size is bigger, so just makes and transfer seat to protrude at this place.Have the gap between the protrusion place of regulating valve seat and the valve body inboard, the turn regulating valve seat is tight against in the valve body inboard its protrusion place, makes that like this space in the valve body is bigger, then spool is packed in the valve body by the mounting hole place.At this moment, has the gap between the end of regulating valve seat and the spool.The turn regulating valve seat makes it draw close to spool, finally makes regulating valve seat be resisted against on the spool.
In above-mentioned integral whole-through diameter ball valve, the internal diameter of described spool is identical with the internal diameter of regulating valve seat.Because the internal diameter of spool is bigger, regulating valve seat is again identical with the internal diameter of spool simultaneously, so just makes that the clear size of opening of whole valve body is bigger.
Compared with prior art, this integral whole-through diameter ball valve has just increased mounting hole, gland etc. on the basis of ordinary ball valve, and therefore, its structure is simpler, and cost is lower.
Because spool is packed in the valve body by the mounting hole place, so just make the size of spool greater than the clear size of opening of valve body, simultaneously, regulating valve seat is again identical with the internal diameter of spool.Therefore, under the bigger situation of spool internal diameter, the clear size of opening of whole ball valve is also corresponding bigger.Such structure can make the flow through fluid flow of this ball valve bigger, thereby makes this integral whole-through diameter ball valve can be adapted in the various big flux pipe systems.
