[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1-Figure 4 A water conservancy pipeline connection device shown in the figure comprises a valve body 3, a mounting seat 4 is fixedly mounted on the upper end of the valve body 3, a guide tube (12) is inserted into the inner side of the valve body 3, a support arm 5 is rotatably mounted on one side of the mounting seat 4, and a long rod 6 is rotatably mounted on the lower end of the support arm 5 on the other side of the mounting seat 4, a circular groove 15 is opened on the upper end of the valve body 3, a straight rod 17 is mounted on the upper end of the support arm 5, the straight rod 17 passes through the circular groove 15 and a reset mechanism is arranged inside, and a flow limiting mechanism is arranged inside the guide tube 12.

[0020] like Figure 2As shown, the middle section of the support arm 5 and the upper surface of the front end of the long rod 6 are both provided with a protrusion 16, and the straight rod 17 is located at the upper end of the protrusion 16 and is provided with a limit ring 7. When the lower end of the long rod 6 rotates toward the side away from the valve body 3, the support arm 5 drives the reset mechanism to move upward.

[0021] The reset mechanism includes an upper seat 9 provided at the inner upper end of the valve body 3 through a distance adjustment mechanism, a lower seat 10 is fixedly installed on the outer surface of the straight rod 17 near the lower end, a spring 11 is provided between the upper seat 9 and the lower seat 10, and the spring 11 is sleeved on the outside of the straight rod 17, and the adjusting rod 8 is driven to move by pulling the long rod 6, and the spring 11 maintains the pressure of the upper seat 9 and the lower seat 10 on the inside of the branch pipe 2.

[0022] The distance adjustment mechanism includes an adjusting rod 8 fixedly mounted on the upper surface of the upper seat 9. The upper end of the adjusting rod 8 vertically slides through the upper surface of the circular groove 15. An adjusting nut 18 is provided on the outer surface of the adjusting rod 8 near the upper end. The adjusting nut 18 is rotatably connected to the upper surface of the valve body 3.

[0023] The flow limiting mechanism includes a valve plate 14 installed at the lower end of the guide pipe 12. The valve plate 14 moves up and down along a slide groove 13 opened on the inner wall of the branch pipe 2. The movement of the valve plate 14 opens the channel between the pipe interface 1 and the branch pipe 2, allowing the water flow in the two channels to circulate.

[0024] like Figure 3 As shown, the surface area of ​​the valve plate 14 is larger than the branch pipe 2. The branch pipe 2 and the pipe interface 1 are limited by the up and down movement of the valve plate 14. The reset mechanism keeps the valve plate 14 pressed down inside the slide groove 13 to avoid damage to the pipeline due to hard contact.

[0025] Working principle: The water conservancy pipeline is fixedly installed in the pipe interface 1 and the branch pipe 2 by bolts, the upper end of the valve body 3 is fixedly installed with a mounting seat 4, a support arm 5 is rotatably installed on one side of the mounting seat 4, and a long rod 6 is rotatably installed at the lower end of the support arm 5 on the other side of the mounting seat 4, and a protrusion 16 is fixedly installed at the front end of the long rod 6 and the upper surface of the middle end of the support arm 5. A limit ring 7 is installed on the upper end of the support arm 5, and a straight rod 17 is fixedly installed at the lower end of the limit ring 7. A circular groove 15 is opened on the upper end of the valve body 3, and the straight rod 17 passes through the circular groove 15 inside the valve body 3. An adjusting nut 18 is rotatably installed on the upper end of the valve body 3, and an adjusting rod 8 is fixedly installed on the lower end of the adjusting nut 18. An upper seat 9 is fixedly installed on the lower end of the adjusting rod 8. A guide tube 12 is slidably inserted at the lower end of the valve body 3, and a lower seat 10 is installed on the upper end of the guide tube 12. A spring 11 is sleeved between the upper seat 9 and the lower seat 10, and the spring 11 is sleeved on the outer side of the straight rod 17. By pulling the long rod 6 away from one side of the outer surface of the valve body 3, the protrusion 16 at the upper end of the long rod 6 lifts the support arm 5, and the rotation of the support arm 5 drives the straight rod 17 to move up and down, and the valve plate 14 fixedly installed at the lower end of the straight rod 17 moves up and down along the slide groove 13 opened on the inner side of the straight rod 17. The up and down movement of the valve plate 14 opens the channel between the pipe interface 1 and the branch pipe 2, so that water flows from different branches can circulate with each other.
