The positioning convex platform that shape positioning groove is adapted.
Further, holding screw is threaded on the taper knob, passes through holding screw between taper knob and lever
It is fixedly connected.
Further, baffle ring is arranged on the upper valve rod, which is located at the junction of taper knob and upper valve rod.
The utility model has the advantages that：
1) blank is integrally forged using mold, and blank is small, and allowance is few, and production cost is low, and ball valve added value is high,
It is light-weight after overall package, convenient for in-site installation；
2) using two valve type structure designs, lacked the dew point that leaks after ball valve assembling, increased the service life of ball valve,
Also reduce the security risk that ball valve uses simultaneously；
3) ball valve is completely using down-mounting type structure design, and valve rod will not be because of during dismounting valve deck replaces sealing ring
Pressure may be retained in pipeline causes valve rod to blow out, and avoids security risk present in use；
4) upper valve rod and lower fixed shaft position are designed using self-lubricating bearing, and ball valve keying torque is small, open and close flexible, increase
Ball valve service life.
