Description
Technical field
This utility model relates to compressed air line interconnection technique field, specifically a kind of pressure-air pipe flange.
Background technology
Compressed air line flange is the connection member of compressed air line system, is mainly used in the latus rectum compressed air system more than or equal to DN40, the connection between pipeline and pipeline, pipeline and equipment.Along with the rising of compressed air system operating pressure, the screw-down torque of pipe flange nut the most significantly raises, thus appears in some narrow space, the problem that compressed air joint cannot be dismantled and install.Further, since flange installation is not in place or compressed air line long-term work is under alternate stress operating mode, gasket seal may be caused to move relative to flange sealing surface, or gasket seal surrounding unbalance stress, all can cause flange generation leakage phenomenon.Existing compressed air pipe flange cannot solve the problems referred to above.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of pressure-air pipe flange, easily installs, better tightness.
For realizing above-mentioned technical purpose, the scheme that this utility model provides is: a kind of pressure-air pipe flange, including boss flange, recessed flange, gasket seal, bolt, packing ring, spring washer, nut, boss flange is the most chimeric with recessed flange and is attached by organizing the screw bolt and nut being circumferentially evenly arranged more, it is provided with gasket seal formation sealing at boss flange and the chimeric of recessed flange, form matched in clearance between boss flange and recessed flange, prevent flange from dislocation being installed.Use gap to coordinate between the external diameter of gasket seal with recessed flange, be possible to prevent gasket seal that dislocation is installed.
And, the internal diameter of the sealing surface internal diameter of gasket seal and two flanges is identical.
And, two sealing surfaces of gasket seal arrange a circle groove, forms double sealing structure.
The beneficial effects of the utility model are: simple in construction, are skillfully constructed；Boss flange coordinates with using gap at the male-female engagement of recessed flange, it can be ensured that boss flange is installed with recessed flange and do not misplaced；The internal diameter of the sealing surface internal diameter of gasket seal and two flanges is identical, can reduce the screw-down torque of nut；Use gap to coordinate between the external diameter of gasket seal with recessed flange, be possible to prevent gasket seal that dislocation is installed；One groove is set on gasket seal, forms double sealing structure, increase sealing reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Wherein, 1, boss flange, 2, recessed flange, 3, gasket seal, 4, bolt, 5, packing ring, 6, spring washer, 7, nut, 8, groove.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
The present embodiment provides a kind of pressure-air pipe flange, as depicted in figs. 1 and 2, including boss flange 1, recessed flange 2, gasket seal 3, bolt 4, packing ring 5, spring washer 6, nut 7, boss flange 1 the most chimeric with recessed flange 2 and by organizing the bolt 4 being circumferentially evenly arranged and nut 7 is attached more, requires that the screw-down torque of all nuts 7 is identical during installation.It is provided with gasket seal 3 formation sealing at boss flange 1 and the chimeric of recessed flange 2, forms matched in clearance between boss flange 1 and recessed flange 2, prevent flange from dislocation being installed.Use gap to coordinate between the external diameter of gasket seal 3 with recessed flange 2, be possible to prevent gasket seal 3 that dislocation is installed.
Further, the internal diameter of the sealing surface internal diameter of gasket seal 3 and two flanges is identical, can reduce the screw-down torque of nut 7.
Further, two sealing surfaces of gasket seal 3 arrange a circle groove 8, form double sealing structure, increase sealing reliability.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement or deformation, these improve or deformation also should be regarded as protection domain of the present utility model.
