Detailed description of the invention
The present invention will be further described with reference to fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5.
As shown in fig. 1 and 5, the steel pipe quick connection hoop comprises a right pressure test hole 1, a left pressure test hole 2, a steel pipe quick connection hoop body 3, a middle partition rib 4, a right inner rubber ring groove 5, a right outer rubber ring groove 6, a left outer rubber ring groove 7 and a left inner rubber ring groove 8. Well spacer 4 is located 3 inner walls intermediate positions of steel pipe high-speed joint hoop body, is protruding form, and rubber ring groove 5 in the right side and rubber ring groove 6 outside the right side that are located 3 inner walls of steel pipe high-speed joint hoop body spacer 4 are twice annular rubber ring recess, and rubber ring groove 7 in the left side and rubber ring groove 8 in the left side are located 3 inner walls of steel pipe high-speed joint hoop body spacer 4's left side, are twice annular rubber ring recess. The right pressure test hole 1 is located at the spacing position between the right inner rubber ring groove 5 and the right outer rubber ring groove 6, the right pressure test hole 1 is threaded and vertically penetrates through the steel pipe quick-connection hoop body 3, the left pressure test hole 2 is located at the spacing position between the left inner rubber ring groove 8 and the left outer rubber ring groove 7, and the left pressure test hole 2 is threaded and vertically penetrates through the steel pipe quick-connection hoop body 3.
The steel pipe quick-connect hoop shown in fig. 1, fig. 2 and fig. 5 is made by rolling a strip-shaped plate with a right inner rubber ring groove 5, a right outer rubber ring groove 6, a left outer rubber ring groove 7, a left inner rubber ring groove 8 and a middle spacing rib 4 by a hot rolling or cold rolling method, and then is made into a steel pipe quick-connect hoop body 3 by welding after being rolled. The strip-shaped plate is processed by cold rolling when the wall thickness of the steel pipe quick connecting hoop body 3 is thin, and the strip-shaped plate is processed by hot rolling when the wall thickness of the steel pipe quick connecting hoop body 3 is thick. The formed groove is used for placing and fixing the sealing rubber ring 11. The outer edge of two connection ports of right side pipeline 9, left side pipeline 10 of connecting tube carries out the chamfer processing, makes things convenient for the pipe insert to have the steel pipe quick connect hoop of sealing rubber ring 11, and the pipe port (right side pipeline 9, left side pipeline 10) inserts steel pipe quick connect hoop in-process and will push at upper and lower left and right side repetitive motion, will prevent that direct brute force from pushing into the damage sealing rubber ring 11 firmly, makes sealing rubber ring 11 lose the sealing effect.
Fig. 3 and 4 show an installation schematic diagram of the present invention, in which when the steel pipe quick connection hoop is inserted into the steel pipe quick connection hoop, the port of the left side pipe 10 is gradually inserted into the steel pipe quick connection hoop and the sealing rubber ring 11 starts to be extruded through the left outer rubber ring groove 7, and in the schematic diagram, the right side pipe 9 is installed in place, and the two sealing rubber rings 11 are fully extruded and filled in the right inner rubber ring groove 5 and the right outer rubber ring groove 6, so as to seal the gap between the socket pipe right side pipe 9 and the steel pipe quick connection hoop. Fig. 4 is an enlarged schematic view of the left pipe 10, the right pipe 9, the sealing rubber ring 11 and the pipe connection sleeve in place.
As shown in figure 5, the left pipeline 10, the right pipeline 9, the sealing rubber ring 11 and the steel pipe quick-connect hoop are installed in place,
when the steel pipe quick connecting hoop is butted and inserted on site, the inserted parts of the steel pipe quick connecting hoop, the sealing rubber ring 11 and the inserted pipeline need to be cleaned up and respectively coated with oil, so that the steel pipe quick connecting hoop is beneficial to insertion. After the butt joint is in place, the right pressure test hole 1 and the left pressure test hole 2 are used for carrying out water pressure leakage detection and pressure test on the oppositely inserted pipelines at the left end and the right end respectively, and whether the sealing ring is in a perfect sealing state in the groove is checked. When the pipe sections are installed in a butt joint mode, the pipe sections can deflect a certain angle according to needs.
