Description
Technical field
The present invention relates to a kind of sealing device, more particularly to a kind of pipe fitting face seals.
Background technology
In airplane component manufacturing process, it is must carry out one that Airplane's Oil Way pipe fitting, which is suppressed,
Important work.Also frequently encounter various oil circuit pipe fittings, especially special form face simultaneously
Pipe fitting.For example, two ends are the pipe fittings of ellipsoidal structure.The mesh of pipe fitting end face seal is mainly inspection
The air-tightness of its weld seam is tested, because fitting structure is special, when suppressing the air-tightness of detection weld seam,
Typically all one end of pipe fitting is welded with metallic plate, metallic plate is opened a circular hole by the other end, will be beaten
Crimping mouth is welded in the circular hole of metallic plate, then will be welded with and suppressed the metallic plate for connecing mouth and be welded on pipe fitting
Oval termination.Then connect mouth by suppressing and suppressed to pipe fitting, examine the air-tightness of its weld seam.
Pipe fitting is suppressed after test ending, must also be sliced off the weld plate at pipe fitting two ends.When expending
Between simultaneously also waste of resource.
The content of the invention
The technical problem to be solved in the present invention：There is provided a kind of easy to disassemble, and sealing reliability
High pipe fitting face seals.
Technical scheme：A kind of pipe fitting face seals, it is characterized in that：Described
Sealing device includes sealing plate 1, pressing part 3 and steel core 10, and steel core 10 is located in pipe fitting,
Coordinate with pipe fitting endoporus for gap, rubber blanket, steel core 10 are installed between steel core 10 and tube wall
End face on be provided with screwed hole, sealing plate 1 is fixed on the end face of steel core 10, is sealingly mounted at
The port of pipe fitting；
Pressing part 3 is provided with the concave surface 11 with tube wall form fit, and pressing part 3 is connected through a screw thread set
On outer tube wall, rubber blanket is installed between pressing part 3 and tube wall.
Improved as one kind of the technical program, the length of concave surface 11 is straight more than the end face of pipe fitting
5~10mm of line length, the design avoids pressing part 3 and damage is caused to body.
Beneficial effects of the present invention：The present invention passes through the sealers such as conventional sealing ring, rubber blanket
Part and the simple part of profile realize end part seal to the pipe fitting of special cross-section, with welded seal
Compare, on the one hand improve sealing reliability, on the one hand improve detachability, after improving
The continuous efficiency for suppressing experiment.
