[0038] This invention provides a device for preventing welding slag from affecting the installation accuracy of pipes and sleeves, such as... Figure 5 and Figure 6 As shown, it includes:

[0039] The circular inner gasket 1 has an outer diameter that is 0.95 to 0.98 times the inner diameter of the sleeve 5. This ensures that the gap between the circular gasket and the sleeve 5 is smaller than the size of the welding slag, preventing welding slag from entering the gap between the circular gasket and the sleeve 5 during welding. This protects the inner surface of the sleeve 5. The circular inner gasket 1 effectively prevents welding slag from affecting the inner surface of the sleeve 5, ensuring the connection quality between the sleeve 5 and subsequent pipes. The high-temperature resistant material used for the inner gasket can withstand the high temperatures during welding and is not easily damaged.

[0040] A ring 2 is disposed at one end of the circular inner pad 1. The outer diameter of the ring 2 is larger than the outer diameter of the sleeve 5, so that the ring 2 can be placed at the port of the sleeve 5.

[0041] Handle 3 is provided on the outer wall of the ring 2 to facilitate the retrieval of the device;

[0042] When using the device, the sleeve 5 is fitted onto the main pipe 4, the device is installed on the end of the sleeve 5 away from the main pipe 4, the inside of the main pipe 4 and the sleeve 5 are welded, and after the welding is completed, the device is taken out by the handle 3.

[0043] In some embodiments of the present invention, the length of the circular inner pad 1 is determined based on the sleeve 5 and the pipe size, so as to cover the pipe installation area and play a role in preventing welding slag.

[0044] In this embodiment, the circular inner pad 1 is made of a high-temperature resistant material. For example, the circular inner pad 1 can be made of materials such as ceramic fiber to prevent the effects of high temperatures during welding.

[0045] In some embodiments of the present invention, a plurality of magnet blocks are evenly distributed inside the ring 2 so as to be attracted to the port of the sleeve 5 by the magnet blocks. That is, the magnet embedded inside the ring 2 is attracted to the steel sleeve 5, which can play a good fixing role. At the same time, the outer diameter of the ring 2 is slightly larger than the outer diameter of the sleeve 5, which facilitates fixing. Meanwhile, the inner diameter of the ring 2 is the same as the inner diameter of the circular gasket, and the ring 2 is connected to the port of the circular gasket.

[0046] In some embodiments of the present invention, the handle 3 is made of a material with a thermal conductivity lower than a set value, that is, a material with poor thermal conductivity is used. Since high temperatures are generated during the welding process, using a material with poor thermal conductivity can prevent the handle 3 from getting hot and make it convenient to pick up during use.

[0047] In some embodiments of the present invention, the sleeve 5 is sleeved on the main pipe 4, and the sleeve 5 is sleeved on the outer wall of the main pipe 4 and fixed to the main pipe 4 by welding.

[0048] This invention provides a method for using a device to prevent welding slag from affecting the installation accuracy of the pipe and sleeve 5. The method includes:

[0049] Fit one end of the sleeve 5 onto the main pipe 4;

[0050] The device for preventing welding slag from affecting the installation accuracy of the pipe and sleeve 5 as described in the above embodiment is fitted onto the other end of the sleeve 5.

[0051] The area inside the sleeve 5 that is close to the main pipe 4 is welded.

[0052] After welding is completed, the device can be removed by hand handle 3. The operation is simple.

[0053] In some embodiments of the present invention, the sleeve 5 is sleeved on the main pipe 4, and the sleeve 5 is sleeved on the outer wall of the main pipe 4 and fixed to the main pipe 4 by welding.

[0054] As can be seen from the above technical solutions, the device and method for preventing welding slag from affecting the installation accuracy of the pipe and sleeve 5 provided in the above embodiments of the present invention can effectively avoid the influence of welding slag on the inner surface of the sleeve 5, ensuring the connection quality between the sleeve 5 and the subsequent pipe; the high-temperature resistant material used for the inner pad can withstand the high temperature during the welding process and is not easily damaged; the forward-facing magnet inside the ring 2 attracts the steel sleeve 5, which can play a good fixing role, and the outer diameter of the ring 2 is slightly larger than the outer diameter of the sleeve 5, which facilitates fixing. At the same time, the handle 3 is convenient to use. The above device and method can effectively prevent welding slag from splashing onto the inner wall of the sleeve 5 during the welding of the sleeve 5 and the pipe, and has the advantages of simple structure, convenient use, significant effect, and reusability.

[0055] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention.
