Improve as the another kind of the utility model, described lock screw is provided with screw head, and the lower end surface of described key is provided with the groove that the shape with the screw head of lock screw is complementary.After adopting this kind structure, described key and lock screw are supporting, and other keys can't unlock, and therefore can prevent that other people from closing or opening ball valve privately.
As a kind of improvement of also having of the utility model, radially overhanging formation one boss of the outer wall of described valve rod axis hole, described interior threaded hole is located on the described boss; Described handle is provided with and is used for when closing ball valve handle is carried out spacing close chock and being used for when opening ball valve, handle being carried out spacing unlatching chock.After adopting this kind structure, when closing or open ball valve, described handle can not rotate excessive.
As a kind of improvement of also having of the utility model, described handle is provided with to be used to cover opens locking aperture and the protective housing of closing locking aperture, and described protective housing is removable to be installed on the described handle.After adopting this kind structure, can prevent that thing from falling into to open locking aperture or close in the locking aperture; And described protective housing is removable is installed on the described handle easy accessibility.
As a kind of improvement of also having of the utility model, described protective housing is provided with latch, and described handle is provided with hinge last, and described latch is inserted in the described hinge last.After adopting this kind structure, can avoid protective housing to break away from handle.
