The connecting channel 31 is tightly connected with the water inlet 11 and the water outlet 16 at the inner groove 12. The sensing rod 21 monitors the pressure of the fluid inside the fully welded ball valve body 1 at all times. When the sensing rod 21 detects that the pressure of the fluid inside the fully welded ball valve body 1 is too high, the data sensing box 22 transmits a signal to the controller 33. The controller 33 controls the telescopic rod 32 to contract and pulls the connecting channel 31 upward. The inflowing fluid is in the inner groove 12. Since the connecting channel 31 moves upward, the cross-sectional area of ​​the inner groove 12 becomes larger, and the pressure of the fluid decreases. Part of the fluid flows into the water outlet 16 through the half channel 34, and part of the fluid overflows. The overflow will flow out from the overflow port 13, and the overflow port 13 is connected to a water pipe.
