Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~4, in the utility model embodiment, a kind of ball valve with lock function, including fluid inlet 1,
Sealing block 2, protecting frame 3, ball valve shell 4, fluid issuing 5, rotation knob 6, screw thread lever 7, valve rod 8, jack 9, crosspiece bar 10, sky
Chamber 11, protecting box 12, door 121, lock 122 and ball 13, the one end of ball valve shell 4 is provided with fluid inlet 1, and ball valve shell 4 is another
One end is provided with fluid issuing 5, and ball 13 is arranged on the centre of ball valve shell 4, and the surface of ball 13 is provided with valve rod 8, valve rod 8
Outside be provided with protecting frame 3, and jack 9 is provided with valve rod 8, the inside of jack 9 is plugged with crosspiece bar 10, crosspiece bar 10
Internal both ends are provided with cavity 11, and one end grafting of screw thread lever 7 enters inside cavity 11, and screw thread lever 7 stretches out protecting frame 3
One end be provided with rotation knob 6, rotation knob 6 outside be provided with protecting box 12.
When being screwed to rotate knob 6, screw thread lever 7 can move, in the utility model, it is preferred that on protecting frame 3 with screw thread
Position corresponding to lever 7 is provided with screwed hole, is connected through a screw thread between screw thread lever 7 and screwed hole.
In order to open with locking door 121, in the utility model, it is preferred that the preceding surface of protecting box 12 is provided with door 121,
It is rotatablely connected between the side of door 121 and protecting box 12 by hinge, and passes through lock between the opposite side of door 121 and protecting box 12
122 are fixedly connected.
In order that fluid will not be between ball valve shell 4 and ball 13 gap outflow, in the utility model, it is preferred that ball
