A new connecting control valve for water supply and drainage design
By aligning the guide rod with the guide groove and inserting the connecting pipe, rotating the threaded cylinder to contact the limiting ring, and controlling the rotation of the sealing gasket using a knob and slider mechanism, the problem of water leakage due to vibration at the pipe connection is solved, achieving a stable sealing effect.

AI Technical Summary
In existing technologies, vibration can cause bolts at pipe connections to loosen, creating gaps and leading to water leakage.
The guide rod is inserted into the guide tube by aligning it with the guide groove. The retaining ring contacts the limiting ring to enhance the sealing performance. The threaded cylinder is rotated to contact the limiting ring, preventing the connecting rod from rotating. The rotation control of the sealing gasket is achieved by combining the knob and slider mechanism, avoiding water leakage caused by slight movement between the threads.
It effectively prevents slight movement of the threaded cylinder caused by water flow vibration, ensures the sealing of pipe connections, and avoids water leakage caused by loose bolts.
