Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a spherical reducer with a variable pipe opening length. Background Art

[0002] Spherical reducers, as specialized pipe connectors, are primarily used for connecting and converting pipes of varying diameters within piping systems. They offer flexible connection capabilities and adapt to complex piping systems. Their spherical design helps reduce fluid resistance at pipe joints, ensuring uniform flow and minimizing water hammer. Their spherical structure offers superior strength and stability, capable of withstanding pressure and impact. They are widely used in construction, industry, pharmaceuticals, and chemical industries.

[0003] Pipes of different diameters can be connected through spherical reducers, but some pipes are fixed and the spacing between the pipes cannot be changed. In some cases, the reserved spacing between the pipes is too large, and the length of the existing spherical reducer orifice cannot be adjusted, resulting in the spherical reducer being unable to connect the pipes. Therefore, a spherical reducer with a variable orifice length is proposed. Summary of the Invention

[0008] Preferably, the threaded rod is installed in the spherical connector through the first bracket, the nozzle body is installed on the threaded rod through the second bracket, and the hollow sealing ring is installed on the nozzle body through the mounting groove. After the hollow sealing ring expands, it will block the gap between the upper interface and the nozzle body.

[0009] Preferably, a mounting groove is provided on the second bracket, and the connecting pipe is installed in the second bracket through the mounting groove. The connecting pipe can transport the gas in the inflation cylinder to the hollow sealing ring.

[0010] Preferably, a through hole is provided at the upper end of the inflation cylinder body, and a driving rod extends out of the inflation cylinder body through the through hole, and the driving rod can drive the piston to move up and down.

[0023] like Figure 2 and Figure 3 As shown, the adjusting nozzle 4 includes a first bracket 401 fixedly installed in the spherical connector 2, a threaded rod 404 is fixedly installed on the first bracket 401, the threaded rod 404 is connected to the second bracket 402, the nozzle body 403 is fixedly installed on the second bracket 402, the outer surface of the nozzle body 403 is provided with a mounting groove 406, the threaded rod 404 is provided with a fixing nut 407, a threaded sleeve 405 is fixedly installed in the middle position of the second bracket 402, and the second bracket 402 is installed on the threaded rod 404 through the threaded sleeve 405.

[0024] Specifically, the user can rotate the threaded sleeve 405, and after rotating the threaded sleeve 405, the second bracket 402 can be moved up and down. After moving the second bracket 402 up and down, the nozzle body 403 can be driven to move up and down, thereby adjusting the extended length of the nozzle body 403 to facilitate connecting pipes together.

[0025] like Figure 2 、 Figure 4 and Figure 5 As shown, the sealing mechanism 5 includes a hollow sealing ring 501 fixedly mounted on the nozzle body 403, an air-filled cylinder 503 fixedly mounted on the second bracket 402, a piston 506 movably mounted in the air-filled cylinder 503, a driving rod 505 fixedly mounted on the piston 506, a connecting pipe 502 is provided between the hollow sealing ring 501 and the air-filled cylinder 503, a lower pressure frame 504 is connected to the threaded rod 404, and the lower pressure frame 504 is connected to the upper end of the driving rod 505, a through hole is opened at the upper end of the air-filled cylinder 503, and the driving rod 505 extends out of the air-filled cylinder 503 through the through hole.

[0026] Specifically, after the fixing nut 407 is rotated downward, it will drive the lower pressure frame 504 to move downward, thereby driving the driving rod 505 to move downward. After the driving rod 505 moves downward, it will drive the piston 506 to move downward, squeezing the gas in the inflation cylinder 503 into the hollow sealing ring 501, causing the hollow sealing ring 501 to expand. After the hollow sealing ring 501 expands, it will block the gap between the upper interface 1 and the nozzle body 403, and the nozzle body 403 is fixed in the upper interface 1 and maintains a seal.

After loosening the lower pressure frame 504, the driving rod 505 will lose its blockage. After the driving rod 505 loses its blockage, the piston 506 can be lifted upward. After lifting the piston 506, the gas in the hollow sealing ring 501 will be sucked into the inflation cylinder 503, causing the hollow sealing ring 501 to shrink. After the hollow sealing ring 501 shrinks, the nozzle body 403 will be loosened. After the nozzle body 403 is loosened, the threaded sleeve 405 can be rotated. After rotating the threaded sleeve 405, the second bracket 402 can be moved up and down, thereby adjusting the extended length of the nozzle body 403.

After turning the fixing nut 407 downward, it will drive the lower pressure frame 504 to move downward.

After the piston 506 moves downward, the gas in the inflatable cylinder 503 will be squeezed into the hollow sealing ring 501, causing the hollow sealing ring 501 to expand. After the hollow sealing ring 501 expands, it will block the gap between the upper interface 1 and the nozzle body 403, and the nozzle body 403 is fixed in the upper interface 1 and kept sealed.
