[0027] During operation, the valve is first installed in the designated position. Multiple sets of limit bolts 206 are used to connect the fixing plate 201 to secure the locking structure, preventing the overall structure from shaking. Next, the support column 215 is used to connect the bracket 217 to support the valve body 1 pipe, providing a solid support. The weight of the valve body 1 is distributed to the support structure, thereby reducing the load on the pipeline system. When the valve body 1 needs to be opened for transmission, the rotating disk 207 is manually grasped in conjunction with the connecting rod 213 to drive the internal valve ball 214 to rotate, so that the valve ball 214 rotates to the designated position and transmits water flow through the flow hole. Next, two sets of cylinders 203 are activated and connected to the telescopic rod 204 to push into the insertion hole to fix the valve ball 214 and lock it in place, providing a stronger locking force to ensure that the valve ball 214 is more stable and reliable in the open or closed state, preventing the valve ball 214 from moving accidentally due to internal pressure, external vibration or impact.

After the valve ball 214 is adjusted by the rotating disk 207, it is inserted into the limiting groove for auxiliary positioning. Then, the limiting plate 211 is connected by the pin 212 and the rotating disk 207 is fixed by the movable rod 209 for secondary fitting and positioning, further locking the position of the rotating disk 207. This ensures the safety of the valve in use, prevents accidental opening or closing due to vibration or impact, reduces the risk of media leakage, and ensures the normal operation of the pipeline system.

[0029] Through the above steps, by using two sets of cylinders 203 connected to the telescopic rod 204, the cylinders are inserted into the valve ball 214 after it is opened or closed for locking and positioning, providing a stronger locking force to ensure that the valve ball 214 is more stable and reliable in the open or closed state, preventing the valve ball 214 from moving unexpectedly due to internal pressure, external vibration or impact, so that the valve can operate stably for a long time under high pressure or harsh conditions. Moreover, the cylinders 203 drive the valve to achieve automatic control, reduce the risk of human error, and improve work efficiency. The spring 210 is connected to the movable rod 209, which is inserted for auxiliary positioning after the valve ball 214 is adjusted by the rotating disk 207, so that the valve can be automatically locked in the open or closed state, preventing accidental opening or closing due to vibration or impact, and ensuring the normal operation of the pipeline system. At the same time, the pin 212 is connected to the limit plate 211 and is positioned again after the movable rod 209 fixes the rotating disk 207, further locking the position of the rotating disk 207.
