Embodiment
1 to 4 the utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one：A kind of bonnet as shown in Figure 1 stop valve with locking mechanism, including bonnet 1, valve rod 3, valve body 5,
Bonnet 1 is fixedly linked with valve rod 3, and for valve rod 3 by being connected provided with flap 4 with the screw thread of valve body 5, connecting place is provided with encapsulant 6；Valve
Bar 3 is connected with the threaded upper ends of flap 4, and the lower end of junction is provided with sealing ring 7；The upper surface of bonnet 1 is provided with arcuate socket；On flap 4
Outer surface is held to be provided with connection ear mount 41, bonnet 1 is additionally provided with tightening screw 2, and tightening screw 2 is through arcuate socket with being connected the spiral shell of ear mount 41
Line is connected；Tightening screw 2 is provided with the lockable mechanism that can limit the rotation of bonnet 1.
Lockable mechanism includes the gear 1 being located on tightening screw 2 and the meshed gears 29 of gear 1, gear 29
