DETAILED DESCRIPTION

[0028] The following is a combination of the appended examples of the present invention Figure 1-8 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention provides a technical solution: a ring-clamp sealing mechanical pipe fitting, comprising a pipe fitting 1, a plug hole 2 is opened on the pipe fitting 1, a ring-clamp joint 3 is inserted in the plug hole 2, a pressure plate 4 is fixed on the ring-clamp joint 3, a sealing gasket 5 is provided between the pressure plate 4 and the pipe fitting 1, and the pressure plate 4 is detachably connected to a back plate 6. The present invention greatly increases the flexibility of operation and use compared with conventional three-way pipe fittings by setting the pipe fitting 1 and the ring-clamp joint 3 as a detachable connection. In the process of pipeline installation, transformation and upgrading, a branch pipe can be directly connected to the system pipeline, which is easy to install; in the process of pipeline emergency repair, the on-site construction speed is fast, there is no need to stop water, the construction excavation amount is small, and only a very small working pit needs to be excavated for operation, which saves a lot of manpower, material resources and time, and achieves the purpose of quickly plugging leaks. For example, in the process of pipeline installation, transformation and upgrading, it is necessary to connect a branch pipe to the original pipeline. The conventional method requires replacing the entire section of pipe fittings, that is, replacing them with pipe fittings with branches. The amount of excavation and replacement in this process is very huge, and it leads to the waste of old pipe fittings, which will lead to a lot of waste of manpower and material resources. However, through the setting of the ring clamp sealing mechanical pipe fitting of this structure, it is only necessary to excavate the part where the branch pipe needs to be installed, make a hole matching the ring clamp joint 3 on the original pipe fitting, and then wear the sealing gasket 5 on the ring clamp joint 3 and plug it into the original pipe fitting. In the pipe fitting, the sealing gasket 5 is pressed against the pipe wall of the original pipe fitting by the pressure plate 4 on the ring clamp joint 3, and then the back plate 6 is pressed against the pipe wall opposite the pressure plate 4, and then the pressure plate 4 and the back plate 6 are fixed, which is very convenient. The ring clamp joint 3 is used to connect the branch pipe. Through the setting of the ring clamp joint 3, it can be quickly connected to the branch pipe. Not only is the installation convenient and fast, but the sealing and firmness of the connection are also very good. In the process of the pipeline installation and modification, the pipe fitting 1 is not needed, so the pipe fitting 1 can be matched with other ring clamp joints 3 and socket holes 2 for use, which has good flexibility. The components used for pipeline emergency repair are the same as the accessories used for pipeline installation and modification, and the leaking place is just blocked with the sealing gasket 5. Therefore, the ring clamp sealing mechanical pipe fitting of this structure can be used as a three-way pipe fitting, and can also be applied to pipeline installation, modification and upgrading and pipeline emergency repair. It has a wide range of applications and good effects. The diameter of the plug hole 2 can be set to be slightly smaller than the diameter of the ring clamp joint 3, so that the ring clamp joint 3 is squeezed into the plug hole 2, thereby improving the sealing and fixation of the two.

[0030] The sealing gasket 5 is made of silicone, and a first through hole 7 for the ring clamp joint 3 to pass through is opened at the center thereof, and a number of water-stop convex rings 8 are fixed on the inner and outer surfaces of the sealing gasket 5. The provision of the water-stop convex rings 8 greatly improves the sealing performance of the sealing gasket 5, and can ensure watertightness even when the pipe fitting 1 and the ring clamp joint 3 are detachably connected.

[0031] Five water-stopping protruding rings 8 are provided on both the inner and outer surfaces of the sealing gasket 5 . This number of water-stopping protruding rings 8 ensures the lowest cost while ensuring the sealing performance.

[0032] The pressure plate 4 includes a first arc block 9 that matches the pipe fitting 1. A second through hole 10 for the ring clamp joint 3 is opened at the center of the first arc block 9. The ring clamp joint 3 is fixed to the inner wall of the second through hole 10. The upper and lower ends of the first arc block 9 are fixed with a first fixing plate 11. The first fixing plate 11 has a plurality of third through holes 12. The back plate 6 includes a second arc block 13 that matches the pipe fitting 1. The upper and lower ends of the second arc block 13 are fixed with a second fixing plate 14. The second fixing plate 14 has fourth through holes 15 that are the same size and number as the third through holes 12. Each group of third through holes 12 and fourth through holes 15 is penetrated by a screw 16, and the screw 16 is provided with a matching nut 17. This is the specific structure of the pressure plate 4 and the back plate 6. The arrangement of the pressure plate 4 and the back plate 6 with this structure greatly improves the compression and fixing effect. The arrangement of the screw 16 and the nut 17 facilitates the fixing and disassembly of the pressure plate 4 and the back plate 6.

[0033] The ring clamp joint 3 includes a plug-in portion 18 arranged at the inner end of the pressure plate 4, and a connecting portion 19 integrally formed with the plug-in portion 18 is provided at the outer end of the pressure plate 4. The outer end of the connecting portion 19 is fixed with a ring clamp joint portion 20 integrally formed therewith, wherein the plug-in portion 18 is inserted into the interior of the pipe fitting 1 through the plug-in hole 2 on the pipe fitting 1, and the ring clamp joint portion 20 is used to clamp other pipe fittings.

[0034] The ring clamp joint 20 includes a first conical portion 21 fixedly connected to the connecting portion 19. The first conical portion 21 is fixed with a first cylindrical portion 22, the first cylindrical portion 22 is fixed with an annular protrusion 23, the annular protrusion 23 is fixed with a second cylindrical portion 24, the second cylindrical portion 24 is fixed with a second conical portion 25, and the second conical portion 25 is fixed with a third cylindrical portion 26. The annular protrusion 23 is provided with a sealing ring inside, which provides a good sealing effect when the pipe is inserted into the ring clamp joint 20. The configuration of the ring clamp joint 20 with this structure not only facilitates the connection of pipes, but also greatly improves the sealing performance and plays a good role in preventing leakage.

[0035] Several arc-shaped grooves 27 are provided on the top surface of the water-stop convex ring 8. Through the setting of the arc-shaped grooves 27, after the water-stop convex ring 8 is pressed, the arc-shaped grooves 27 can act as suction cups, firmly adsorbing the pressure plate 4 and the back plate 6, thereby improving the fixation on the one hand and the sealing on the other hand.

[0036] The heights of the plurality of water-stopping protruding rings 8 on the same surface of the sealing gasket 5 gradually increase from the inside to the outside, and this arrangement further improves the sealing performance of the sealing gasket 5.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
