This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] Most ball valves are composed of a valve body, a ball, a valve stem and a handle. The valve body is usually designed with a large hole running through the center. From one side to the other, the ball is tightly placed on the mold inside the pipe opening (caliber). It is directly connected to the operating handle of the valve. Rotate the handle, usually through a quarter turn of 90 degrees, and the valve stem drives the ball to be axially rotated inside the caliber to complete the opening of the valve. Rotate the handle another 90 degrees in the other direction to close the valve.

[0004] In the current existing technology, when installing a traditional ball valve, the flanges at both ends of the valve body are mostly aligned with the flanges at the outlet of the pipeline, and then the valve body is fixed to the pipeline by passing through the flanges. During installation, the operator needs to tighten the bolts multiple times, resulting in poor installation efficiency and very inconvenient operation, which affects the practicality of the ball valve.

[0026] During operation, the ball 2 is placed inside the valve body 1, one end of the positioning rod 4 is rotated and inserted into the bottom of the ball 2, and then the valve stem 3 is passed through the top of the valve body 1 and engaged with the top of the ball 2. The valve button 5 is rotated to drive the valve stem 3 to rotate, and then the ball 2 is rotated to complete the opening and closing of the valve. When the valve body 1 needs to be installed on the pipeline, the flange 6 is aligned with the connecting pipe 7 by moving the valve body 1, and the sealing ring 19 is inserted into the sealing groove 20 to prevent leakage at the connection. Then the first ring 11 and the second ring 15 are sleeved on the outside of the flange 6 and the connecting pipe 7, so that the opening groove 12 is engaged with the outside of the flange 6 and the connecting pipe 7. After the first ring 11 and the second ring 15 are fixed together, the installation of the ball valve is completed. The above method is convenient for the staff to install and disassemble the ball valve, and the installation efficiency and practicality are improved.

Multiple through holes 8 are provided on the outside of each flange 6 and connecting pipe 7, and a plug rod 9 is sleeved inside each through hole 8, and a connecting block 10 is fixedly connected at both ends of each plug rod 9. The outer wall of one end of each connecting block 10 is fitted and connected to the inside of the arc block 18, and one side of the connecting block 10 is fitted to the inner wall of the arc block 18 through the arc groove 17, and each plug rod 9 is installed inside the through hole 8 through the arc block 18.

[0028] During operation, after the flange 6 is attached to one side of the connecting pipe 7 and the multiple through holes 8 are aligned, the plug rods 9 are respectively inserted into the through holes 8, and the connecting blocks 10 at both ends are exposed, and then the first sleeve ring 11 and the second sleeve ring 15 are moved to clamp the arc groove 17 on the outside of the connecting block 10, so that the arc clamping block 18 is clamped inside the connecting block 10. In the above manner, the plug rod 9 can be fixed inside the through hole 8, and the plug rod 9 can be used to prevent the flange 6 and the connecting pipe 7 from rotating. This prevents the structure from being damaged during use and improves the practicality of the ball valve.

[0029] Further, such as Figure 4 As shown, both ends of each first ring 11 are fixedly connected with a rectangular block 13, and the inner walls of both ends of each rectangular block 13 are slidably connected with a clamping block 14. Both ends of each second ring 15 are provided with a rectangular groove 16, and the inner wall of each rectangular groove 16 is clamped and connected with the outer wall of the rectangular block 13. One side of each clamping block 14 is fitted on one side of the second ring 15 through the rectangular block 13, and one side of each second ring 15 is fitted on one side of the first ring 11 through the second ring 15.

[0030] During operation, after the first sleeve 11 and the second sleeve 15 are engaged on the outside of the flange 6 and the connecting pipe 7, one end of the rectangular block 13 is passed through the rectangular groove 16, and the thrust of the sliding of the rectangular block 13 is utilized to make the clamping block 14 retract into the inside of the rectangular block 13.

[0031] Working principle: When the valve body 1 is installed on the pipeline, the valve body 1 is moved to align the flange 6 with the connecting pipe 7, and the sealing ring 19 is inserted into the sealing groove 20. After aligning the multiple through holes 8, the plug rods 9 are respectively inserted into the through holes 8, and the connecting blocks 10 at both ends are exposed. Then the first ring 11 and the second ring 15 are sleeved on the outside of the flange 6 and the connecting pipe 7, and the arc groove 17 is clamped on the outside of the connecting block 10, so that the arc clamping block 18 is clamped inside the connecting block 10.
