A first plugging plate 22 for plugging the liquid inlet 11, a second plugging plate 23 for plugging the first liquid outlet 12, and a sliding rod 241 are penetrated through the sealing plate 21. The first plugging plate 22, the second plugging plate 23, and the sliding rod 241 are slidably sealed with the sealing plate 21 (wherein insertion blocks are symmetrically provided on the sliding rod 241, and slots matched with the insertion blocks are provided on the sealing plate 21.

The first driving rods 221, the second driving rods 231, and the third driving rods 242 are all rotatably connected inside the fixed box 2. A third plugging plate 24 for plugging the second liquid outlet 13 is provided at one end of the sliding rod 241 away from the third driving rod 242 (the first plugging plate 22, the second plugging plate 23, and the third plugging plate 24 are all slidably sealed with the liquid inlet 11, the first liquid outlet 12, and the second liquid outlet 13). First driving members 25, second driving members 251, and third driving members 253 respectively connecting the first driving rods 221, the second driving rods 231, and the third driving rods 242 are provided outside the fixed box 2. The first driving member 25 can drive the first driving rod 221 to rotate, the second driving member 251 can drive the second driving rod 231 to rotate, and the third driving member 253 can drive the third driving rod 242 to rotate; when the first driving member 25, the second driving member 251, and the third driving member 253 are turned on, the first driving member 25, the second driving member 251, and the third driving member 253 can drive the first driving rod 221, the second driving rod 231, and the third driving rod 242 to rotate. The first plugging plate 22, the second plugging plate 23, and the sliding rod 241 cannot rotate with the first driving rod 221, the second driving rod 231, and the third driving rod 242 (the first plugging plate 22, the second plugging plate 23, and the sliding rod 241 are all restricted by the sealing plate 21).

During normal use, the second liquid outlet 13 can be blocked by the third blocking plate 24 so that the liquid enters from the liquid inlet 11 and is discharged from the first liquid outlet 12. If the sensors detect that the liquid flowing inside the pipeline is abnormal (such as too high flow rate, too high pressure, etc.), the controller can make a judgment according to the preset parameters, open the second liquid outlet 13, and use the first liquid outlet 12 and the second liquid outlet 13 for drainage. It is also possible to realize the intelligent automatic regulation of the liquid flow rate and direction inside the tee body 1 by using the sensors, the controller, the first driving member 25, the second driving member 251, and the third driving member 253 according to the actual application scenario.

[0028] The utility model provides a self-opening and self-checking three-way pipe, which comprises a first blocking plate, a second blocking plate and a third blocking plate. By using sensors, a controller, a first driving member, a second driving member and a third driving member, the opening and closing of the first blocking plate, the second blocking plate and the third blocking plate are controlled, so as to realize the intelligent automatic regulation of the liquid flow rate and direction in the three-way pipe body. When the sensor detects an abnormality, the valve can be automatically opened or closed, effectively avoiding the occurrence of accidents, improving the safety of the pipeline system, reducing the manual operation frequency, reducing the risk of misoperation, and improving the operation efficiency and stability of the pipeline system; A placement groove is provided at one end of the sealing plate close to the third blocking plate. When the second liquid outlet needs to be fully opened, the placement groove can reduce the impact of the liquid inside the three-way pipe body on the third blocking plate and extend the service life of the third blocking plate.
