Detailed Description
As shown in fig. 1, the argon filling protection device for the small-caliber nickel-based composite pipe joint weld comprises a communicating pipe 4, wherein two ends of the communicating pipe 4 are both fixed with argon gas bags 2 communicated with the communicating pipe, and the argon gas bags 2 are high-temperature resistant elastic rubber air bags. Be fixed with two fixed disks on communicating pipe 4 between two argon gasbag 2, the fixed disk sets up with communicating pipe 4 is concentric, and the fixed disk outer fringe is fixed with sealing ring 5, sealing ring 5 is the elastic rubber ring, and 4 middle parts of communicating pipe are seted up there is the gas pocket, and inserted bar 7 runs through the gas pocket, is fixed with rubber sleeve 6 on the inserted bar 7, and rubber sleeve 6 and gas pocket sealing connection carry out the shutoff to the gas pocket.
The fixed disk comprises a rubber ring pad 8, the inner edge of the rubber ring pad 8 is in sealing contact with the outer edge of the communicating pipe 4, the outer edge of the rubber ring pad 8 is fixedly connected with the inner edge of the sealing ring 5, a paper ring 3 is fixed in the sealing ring 5 on one side of the rubber ring pad 8, the inner edge of the paper ring 3 is fixedly connected with the communicating pipe 4, the paper ring 3 is located between the rubber ring pad 8 on one side of the paper ring 3 and the argon gas bag 2, and the paper ring 3 is formed by pressing water-soluble paper.
Before welding the connection of the small-caliber nickel-based composite tubes, the protective device is placed into the small-caliber nickel-based composite tubes, the small-caliber nickel-based composite tubes on two sides are filled with the argon gas bags 2 and the fixed disks, the protective device is moved, the inserted rod 7 penetrates through the joint of the two small-caliber nickel-based composite tubes, the fixed disks seal the small-caliber nickel-based composite tubes on one side of the inserted rod, during welding, argon gas is introduced into the small-caliber nickel-based composite tubes between the fixed disks on the two sides and is welded, when a weld seam needs to be closed, the rubber sleeve 6 is pulled out of the air hole through the inserted rod 7, at the moment, the argon gas in the argon gas bags 2 is filled into the small-caliber nickel-based composite tubes between the two fixed disks through the air hole, and during closing welding of the weld seam, the argon gas is still used for protection, so that the quality of the weld seam can be guaranteed. When the small-caliber nickel-based composite pipe is cleaned, the protection device can be discharged by utilizing pipeline dredging equipment. When this protection device appears the card and hinders the phenomenon, to leading to water in the small-bore nickel base composite pipe of this protection device both sides, utilize water to soak paper ring 3, after paper ring 3 dissolved in water, sealing ring 5 and rubber ring pad 8 are collapsible, make things convenient for this protection device to discharge.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
