Embodiment Construction
[0018] Below the present invention is described in further detail, see Figure 1 to Figure 9 . Pipe fitting sealing device, a pipe fitting sealing device includes: sealing plate 1, sealing bolt 2, pressing part 3, sealing rubber pad 4, bolt 5, rubber plate 6, rubber pad 7, wing nut 8, O-ring 9 , steel core 10.
[0019] First wrap the steel core 10 with the rubber plate 6 and put it into one end of the pipe fitting. Then stick the rubber pad 7 to the depressed plane 11 of the pressing part 3 . The bolt 5 passes through the No. I hole 12 on the pressing part 3, and the pressing part 3 is joined together by the wing nut 8. Then put the combined pressing part 3 on the end of the pipe, and the steel core 10 is at the same distance from the end of the pipe. At this time, the wing nut 8 will be rotated so that the pressing part 3 will compress the steel core 10 in the pipe fitting, and the steel core 10 will keep a smaller gap with the pipe fitting as much as possible. The seali...

The invention relates to a sealing device, in particular to a pipe fitting end face sealing device. The pipe fitting end face sealing device comprises a sealing plate (1), a press fitting piece (3) and a steel core (10); the steel core (10) is located in a pipe fitting, and is in clearance fit with an inner hole of the pipe fitting; a rubber gasket is arranged between the steel core (10) and the pipe wall; threaded holes are formed in the end face of the steel core (10); the sealing plate (1) is fixed to the end face of the steel core (10) and is sealed at a port of the pipe fitting; the press fitting piece (3) is provided with a concave surface (11) matched with the shape of the pipe wall; the press fitting piece (3) is connected with and sleeves the outer pipe wall through threads; and a rubber gasket is arranged between the press fitting piece (3) and the pipe wall. Through commonly-used sealing components like a sealing ring and the rubber gaskets, and components in simple shapes, end sealing on the pipe fitting having the special cross section is realized. Compared with welding sealing, the sealing reliability is improved, the detachability is improved, and the efficiency of a subsequent pressurizing experiment is improved.
Description
technical field [0001] The invention relates to a sealing device, in particular to a pipe fitting end face sealing device. Background technique [0002] In the manufacturing process of aircraft parts, the pressure of aircraft oil pipe fittings is an important work that must be carried out. At the same time, various oil pipe fittings are often encountered, especially pipe fittings with special shapes. For example, pipe fittings with elliptical configurations at both ends. The purpose of the end face sealing of pipe fittings is mainly to test the airtightness of the weld seam. Due to the special structure of the pipe fittings, when testing the airtightness of the weld seam under pressure, generally one end of the pipe fitting is welded to death with a metal plate, and the other end is opened with a metal plate. For the round hole, weld the pressing nozzle in the round hole of the metal plate, and then weld the metal plate welded with the pressing nozzle to the elliptical end...
