The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 1, an embodiment of the present invention provides a welded pipe cooling water joint for providing cooling protection to welded pipe 300 during welding, including:

the outer edge of the plug 100 is provided with a compression check ring 200, and the plug can be in close fit connection with the inner wall of the overlaying pipe 300 through the compression check ring 200;

one end of the swivel joint 400 is connected to the inner diameter of the plug 100 in a matching manner, and can rotate relative to the plug 100.

In this embodiment, the swivel joint 400 is used for introducing circulating water, one end of the swivel joint 400 can be in matched connection with the inner diameter of the plug 100, and the plug 100 can be connected with the inner wall of the surfacing pipe 300 through the compression retaining ring 200, so that the cooperation of the swivel joint 400 and the plug 100 can ensure that the circulating water can be stably poured into the surfacing pipe 300, wherein the compression retaining ring 200 can improve the matching tightening degree between the outer edge of the plug 100 and the inner wall of the surfacing pipe 300, so as to limit the installation position of the plug 100, and enable the plug 100 to be matched with the surfacing pipe 300 more tightly; and, when the installation, rotary joint 400 can rotation angle, be equivalent to self can provide the technology pipe of different angles, need not to cut technology pipe, and production efficiency is higher, can be applicable to the installation under the different environment, and the installation is more convenient and the consumptive material is few, and is with low costs. Therefore, the utility model discloses simple structure, simple to operate, the consumptive material is few, and is with low costs, need not additionally to set up or cutting process pipe, can plug into the surfacing pipe 300 well, guarantees that the circulating water can be poured into in the surfacing pipe 300 steadily, improves its production efficiency.

Specifically, the plug 100 and the rotary joint 400 may be implemented by using a taper structure or a circular truncated cone or a column structure, but not limited thereto, the material of the plug 100 is preferably common plastic material, and has better extrudability and wear resistance, such as nylon, rubber, etc.; further, referring to fig. 1 and 2, in order to stabilize both the installation of the swivel joint 400 and the water passage, therefore, the swivel joint 400 is realized by adopting the screw thread end 410 and the water inlet end 420 which are integrally connected, the water inlet end 420 is used for realizing the functions of water passing and rotation, the screw thread end 410 is attached with threads which can be directly communicated with the inner teeth at the interface of the plug 100 to realize the internal thread connection, compared with the common external tooth connection, the external tooth connection does not need to be additionally provided with a nut for fixing, therefore, the inventor designs the coupling washer 500 more simply and conveniently, and the coupling washer 500 may be one or more, and all of them are arranged between the threaded end 410 and the interface of the plug 100, the connection between the screw thread end 410 and the interface of the plug 100 is smoother, the matching connection is realized, the installation friction force between the screw thread end and the plug can be reduced, and the dustproof effect is achieved to a certain extent, so that the installation is more convenient and reliable.

Further, a nut locking gasket 600 is further arranged, so that the outer edge of the plug 100 can be in matched connection with the pipeline opening of the surfacing pipe 300, namely, the installation position of the plug 100 at the pipeline opening is limited by the nut locking gasket 600, one end of the plug 100 is always kept connected with the pipeline opening of the surfacing pipe 300, the other end of the plug 100 is already connected with the inner wall of the surfacing pipe 300, and therefore the plug 100 can be stably installed by matching the plug 100 and the surfacing pipe, and the plug 100 is further fixed by tightening the nut 700, so that the installation is more stable.

Specifically, when the plug 100 and the rotary joint 400 are installed, the outer edge of the plug 100 is close to the pipe orifice of the overlaying pipe 300, the plug 100 is compressed through the nut locking gasket 600, the tensioning nut 700 is installed on the plug 100, when the tensioning nut 700 is gradually screwed down, the plug 100 is matched with the inner wall of the overlaying pipe 300 and is also closely contacted, finally, the plug 100 is completely and stably installed through the compression retaining ring 200, at this moment, water can be introduced into the plug through the rotary joint 400, and the operation is very convenient.

Further, referring to fig. 2, the inventor also designs a sealing mechanism 800 for further enhancing the sealing effect between the plug 100 and the inner wall of the build-up welded pipe 300, which is disposed to be closely attached to the pressing retainer 200 to assist in sealing, and in practice, whether the sealing mechanism 800 is needed or not can be selected according to the inner wall condition of the build-up welded pipe 300.

Specifically, the sealing mechanism 800 can adopt a sealing ring (sleeve) or an anaerobic type sealant, and the above specific structure has a good sealing effect, is low in cost and convenient to install, and is suitable for industrial production.
