The tapered end front end of lower lock stretches out in the surface of lock body of lock, with horizontal tapered end hole and valve rod on set counterbore sliding connection, will
Valve rod is pinned to be fixed；Axle positioning apparatus for circumferential direction is additionally provided between described through-hole surfaces and cylinder lock outer peripheral face；Described is logical
Axial direction positioning device is additionally provided between bottom hole end and cylinder lock bottom face.
Described axle positioning apparatus for circumferential direction is to set a detent by the side surface of valve rod hole one of valve body in through hole, in cylinder
The lock body of lock sets a protruding pin, protruding pin and detent positioning in mating connection by the side surface of tapered end one locked.
Described axial direction positioning device is to set an internal projecting ring in through hole one end port part, the lock body breech face of cylinder lock with it is interior
The inner surface of bulge loop is mutually positioned by connection.
Described through hole is shaped as semicircle by the detent that sets of the side surface of valve rod hole one of valve body.
The lock body of described cylinder lock is shaped as semicircle by the protruding pin that sets of the side surface of tapered end one locked.
Compared with prior art, the utility model has the advantage of：Due to relatively independent using lock and ball valve two parts
Frame mode Combination Design, maintains the constant of ball valve body main structure and performance, meanwhile, make lock section point in lock open shape
During state, whole lock body part can freely be removed from valve body.When using, when find lock out existing defect when can in time individually more
Renew lock, the use of valve is not influenceed.And, install and use and its convenient, as long as being inserted in the lockhole set on valve body when using
After lock body combines two parts, you can locked come the valve rod to valve with by the opening and closing locked, limit it and rotate
Realize carrying out locking control to the open/close states of ball valve.And with using it is reliable, maintenance cost is low the characteristics of.
