Description

Technical Field

[0001] The utility model specifically relates to an argon-filling protection component for zirconium material pipeline welding. Background Art

[0002] Zirconium pipe is a pipe made of metal zirconium or zirconium alloy. Since zirconium has good nuclear properties and high corrosion resistance, zirconium pipe is usually used in environments that require corrosion resistance, high heat resistance and strong radiation resistance. The use of zirconium pipe not only improves the operating efficiency of the equipment, but also extends the service life of the equipment and reduces maintenance costs. When the zirconium pipe needs to be connected, repaired or made into a specific structure, it is necessary to weld the zirconium pipe. However, due to the particularity of the material of the zirconium pipe, the welding joint is prone to oxidation, which affects the welding quality. Generally, a protective component is used to inject argon gas into the zirconium pipe to protect the welding gap, avoid oxidation of the zirconium pipe, and ensure welding quality.

[0003] However, when existing zirconium pipes are welded, there is no corresponding argon filling protection component, and argon filling protection is usually adopted for the whole pipe. Not only is the argon filling efficiency low, the argon filling process takes a long time, and the argon consumption is large, which easily leads to waste of resources.

[0004] Therefore, it is necessary to invent a zirconium pipe welding argon filling protection component to solve the above problems. Utility Model Content

It is more targeted and indirectly reduces the filling time of argon. The argon filling efficiency is high, and the waste of argon is avoided.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The utility model provides Figure 1-6 The zirconium pipe welding argon filling protection assembly shown comprises a disc 1 which can be inserted into a zirconium pipe 12, a through hole 2 is provided on the side of the disc 1, and a plurality of transmission holes 3 connected to the through hole 2 are provided inside the disc 1, and an annular groove 4 connected to the transmission hole 3 is also provided on the outer ring of the disc 1 for containing argon gas;

[0031] It also includes a main rod 5, which is installed on the side of the disc 1 and is used to push the disc 1 to move to the welding position to form welding protection.

[0032] In one embodiment, an exhaust channel 6 is opened on the inner wall of the disc 1 located at the groove 4, and the exhaust channel 6 is arranged in a Z shape. An exhaust pipe 7 is installed at the outlet of the exhaust channel 6, which is used to exhaust the air in the groove 4 when argon is flushed. In addition, the Z-shaped exhaust channel 6 prevents the argon gas filled in the groove 4 from flowing out easily.

[0033] In one embodiment, an air inlet channel 8 is opened inside the main rod 5, and the air inlet channel 8 is connected to the through hole 2. A gas nozzle 9 is installed at the end of the main rod 5 away from the disc 1, and the gas nozzle 9 is connected to the air inlet channel 8. The number of the transmission holes 3 is not less than four, and they are evenly distributed in a circular array inside the disc 1, so that the staff can fill the groove 4 with argon gas. The setting of multiple transmission holes 3 allows the argon gas to be quickly and evenly filled into the groove 4.

[0034] In one embodiment, a plurality of support plates 10 are provided at both ends of the disc 1, and the support plates 10 are evenly distributed on both sides of the disc 1 in a circular array, and a universal wheel 11 is installed on each of the support plates 10. When the disc 1 moves in the zirconium pipe 12, the universal wheel 11 can contact the inner wall of the zirconium pipe 12, so that the disc 1 moves smoothly, and the universal wheel 11 can also provide support and protection for the zirconium pipe 12 inside the zirconium pipe 12 when the zirconium pipe 12 is welded, thereby ensuring the welding quality of the zirconium pipe 12.

[0035] The specific implementation method is as follows: when the utility model is used, Figure 1 , 5 As shown in Figure 6, first, the staff wraps a circle of adhesive tape 13 around the outside of the welding point of the two sections of zirconium pipes 12 to be welded, and then pushes the disc 1 to the welding point by pushing the main rod 5. At this time, an airtight chamber is formed between the groove 4 and the welding point under the cover of the side wall of the disc 1 and the adhesive tape 13;

[0036] Then the staff connected the external gas injection device to the gas nozzle 9, injected the argon gas into the gas inlet channel 8 through the gas nozzle 9, and then transported it to the transmission hole 3 through the through hole 2, and then quickly reached the airtight chamber. At this time, the air in the airtight chamber can be discharged into the exhaust pipe 7 through the exhaust channel 6, and then discharged from the airtight chamber;

[0037] At this time, the staff tear off the tape 13 and weld the two sections of the zirconium pipe 12, while the argon gas in the airtight chamber ensures the welding quality of the two sections of the zirconium pipe 12 and prevents the zirconium pipe 12 from being oxidized during welding;

[0038] In summary, when the zirconium pipe 12 welding argon filling protection component is used, the groove 4 is arranged on the disc 1, and an airtight chamber is directly formed with the welding part of the two sections of the zirconium pipe 12. While protecting the welding part from oxidation, the required amount of argon gas is greatly reduced, and the consumption of argon gas is reduced. It is more targeted, indirectly reduces the filling time of argon gas, has high argon filling efficiency, and avoids the waste of argon gas.

[0039] This embodiment specifically solves the problem that the current zirconium pipe 12 in the prior art has no corresponding argon filling protection component during welding, and usually adopts argon filling protection for the whole pipe, which not only has low argon filling efficiency and a long argon filling process time, but also consumes a lot of argon and easily causes waste of resources.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
