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

Technical Problem

In existing technologies, vibration can cause bolts at pipe connections to loosen, creating gaps and leading to water leakage.

Method used

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.

Benefits of technology

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.

Abstract

The utility model discloses a novel connection control valve for water supply and drainage design relates to control valve technical field, the utility model discloses a valve body is provided with the docking mechanism on the valve body, the inside control mechanism of valve body is provided with, the docking mechanism includes the water pipe, and one end of water pipe penetrates valve body outer wall and extends, and the inside water pipe is seted up with the guide groove, and the inside fixed connection of water pipe has the sealing ring. The utility model discloses through rotating the thread cylinder, make the thread cylinder along the thread seat close the one end of valve body to the limit ring direction removal, with the rotation of thread cylinder, the thread cylinder will gradually move to the above connection rod, until the thread cylinder and limit ring contact, at this moment, the thread cylinder will limit the connection rod, prevent the connection rod around the rotation of the rotating rod, at this moment, the baffle will limit the blocking ring, and the docking of water pipe and docking pipe is completed, and because the thread cylinder slightly removes when the water flow vibration leads, at this moment, the thread cylinder still will limit the connection rod, avoid the thread cylinder slightly removes and makes the docking place produce the gap.
