[0024] Example

[0025] The fixing device 3 generally uses a fixing structure such as screws or bolts to fix the control handle 2 in the normally open state. However, such a fixing device 3 requires frequent loosening of the screws or bolts each time the control handle 2 is closed, which is very inconvenient when it is needed to be closed.

[0026] To do this, see Figure 1-3 The utility model provides a hydraulic ball valve fixing device for a loading building, comprising: a hydraulic ball valve body 1, a control handle 2 is installed on the top of the hydraulic ball valve body 1, and is characterized in that a fixing device 3 is connected between the control handle 2 and the hydraulic ball valve body 1;

[0027] The fixing device 3 can, on the one hand, facilitate fixing the control handle 2 in the normally open state, and on the other hand, can facilitate disassembly, assembly and replacement between the control handle 2 and the hydraulic ball valve body 1 .

[0028] Further Figure 1-3 As shown, it is worth specifically explaining that the fixing device 3 includes a movable through hole 33 opened on the control handle 2, and the movable through hole 33 is also connected to a key groove 34 opened on the control handle 2. A U-shaped positioning rod 31 and a key strip 32 are movably inserted in the movable through hole 33 and the key groove 34 respectively. The key strip 32 is fixedly connected to the outer side of the U-shaped positioning rod 31. One end of the U-shaped positioning rod 31 is threadedly connected with a nut 35, and the other end is clamped in the positioning hole 310 set at the bottom end of the Z-shaped plate 37.

[0029] The key bar 32 can prevent the U-shaped positioning rod 31 from rotating in the movable through hole 33 , thereby preventing the end of the U-shaped positioning rod 31 away from the nut 35 from being clamped in the positioning hole 310 .

[0030] Further Figure 1-3As shown, it is worth explaining in detail that a spring 36 movably sleeved on the outside of the U-shaped positioning rod 31 and the key bar 32 is provided between the bottom end of the nut 35 and the top end of the control handle 2, and the two ends of the spring 36 are movably overlapped on the bottom end of the nut 35 and the top end of the control handle 2 respectively.

[0031] By loosening the nut 35 , the spring 36 , the U-shaped positioning rod 31 and the key bar 32 can be disassembled and replaced.

[0032] Further Figure 1-3 As shown, it is worth to explain in detail that a through hole 371 is opened on the Z-shaped plate 37, and a hand screw 38 is movably inserted in the through hole 371, and the bottom end of the hand screw 38 is threadedly connected to the screw hole 39 opened on the hydraulic ball valve body 1.

[0033] After the hand screws 38 are loosened, the Z-shaped plate 37 can be removed from the hydraulic ball valve body 1 .

[0034] In summary: when the fixing device 3 is used, the end of the U-shaped positioning rod 31 away from the nut 35 will be clamped in the positioning hole 310 set at the bottom end of the Z-shaped plate 37 due to the rebound effect of the spring 36, thereby fixing the control handle 2 of the hydraulic ball valve body 1 to prevent it from malfunctioning due to external interference factors, thereby avoiding system failures that affect the normal operation of the system. Secondly, when the overall fixing device 3 needs to be replaced, the nut 35 and the hand screw 38 can be loosened to facilitate the disassembly and replacement of the various components on the fixing device 3. Its structural design is simple and easy to operate.
