[0020] Example 1:

[0021] like Figures 1-2 As shown, a flow-through pool flange sealing structure includes a flange 1, an adapter 2, a sensor 3, and a clamp 4. The flange 1 has a shaft hole at its center, and one end of the adapter 2 passes through this shaft hole. The adapter 2 also has a through hole at its center, through which the detection portion of the sensor 3 passes. An O-ring seal is fitted onto the portion of the sensor 3 passing through the shaft hole to seal the gap between the detection portion of the sensor 3 and the inner wall of the through hole. The clamp 4 is used to fix the sensor 3 to the adapter 2, and a sealing gasket is provided on the inner wall of the clamp 4. The adapter 2 is a cylindrical column, and a disc-shaped protrusion is provided on one side of the adapter 2. The flange 1 is screwed to the disc-shaped protrusion. The sensor 3 includes a cylindrical head for housing the control system and a circular probe for detection. The cylindrical detection part has a head diameter larger than the detection part diameter. An outwardly turned edge is provided on the side of the head near the detection part. An adapter 2 has a flange corresponding to the turned edge at one end near the head. A stepped cylindrical surface is provided at the end of the through hole of the adapter 2 near the detection part, with the diameter of the stepped cylindrical surface smaller than the diameter of the through hole. The clamp 4 includes a first semi-circular ring and a second semi-circular ring. One end of the first semi-circular ring is hinged to one end of the second semi-circular ring. The other end of the first semi-circular ring has a threaded hole into which a locking bolt is threaded. The end of the second semi-circular ring not connected to the first semi-circular ring has a groove. A locking nut is threaded onto the locking bolt, and the locking nut has a tightening part.
