Abstract
The utility model discloses a sealing gasket for a mechanical branch, which comprises an annular gasket body, an inner ring bulge and an outer ring bulge are arranged on the bottom surface of the annular gasket body, and extend downwards, the space between the inner ring bulge and the outer ring bulge is taken as a ring groove, the inner ring bulge is higher than the outer ring bulge, a liquid inlet groove is arranged on the inner vertical surface of the inner ring bulge, and a ring rib is arranged on the top surface of the gasket body. The sealing gasket is simple in structure and has the advantage of good sealing effect.
Description
Technical field
The utility model relates to a kind of mechanical three-way sealing gasket.
Background technique
When needs on pressure piping during mounting pipe cassette mechanical three-way, need to open a discharge hole at the correct position of pipeline earlier, this position mounting pipe cassette mechanical three-way at pipeline, between mechanical three-way and pressure piping, be fitted with seal washer, existing packing ring is in the form of a ring a rubber pad, rely on mechanical three-way last slice and following sheet between clamping bolt with the rubber pad compression realizing sealing, owing to still there is the poorly sealed phenomenon that causes seepage in rubber pad after compressing, its sealing effect is undesirable.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of mechanical three-way sealing gasket of good sealing effect.
For addressing the above problem, a kind of mechanical three-way that is provided comprises in the form of a ring packing ring body with sealing gasket, and its structural feature is: it is protruding and outer shroud is protruding that the bottom surface of packing ring body is provided with down the interior ring of stretching, and the space between the protruding and outer shroud of interior ring is protruding is an annular groove.
After adopting said structure, because it is protruding protruding with outer shroud that the bottom surface of packing ring body is provided with down the interior ring of stretching, in the space of the protruding and outer shroud of ring between protruding be annular groove, when on pressure piping, mechanical three-way being installed, the utility model is arranged in the groove of sheet under the mechanical three-way, its top is fitted on the pressure piping, fit in the bottom surface that the protruding and interior ring of outer shroud is protruding and the bottom surface of groove, under the effect of clamping bolt, protruding and the protruding compression simultaneously of outer shroud of interior ring, the air or the liquid that are positioned at annular groove can form liquid sealing, can form triple seal at this surface of contact like this, are not prone to the seepage phenomenon.The utility model is simple in structure, has advantage of good sealing effect.
As improvement of the present utility model, described in the protruding height of ring less than the protruding height of outer shroud, small amount of liquid is entered in the annular groove from the protruding interior the inside of interior ring, when clamping bolt, effectively form liquid sealing.
As further improvement of the utility model, the protruding interior facade of interior ring is provided with lead channel, helps entering of liquid.
As further improvement of the utility model, the end face of described packing ring body is provided with the ring convex tendon, can increase effective area of contact that the sealing pad contacts with pressure tube when fastening, improves sealing.
As further improvement of the utility model, the protruding outer surface of outer shroud is provided with the location convex tendon, the utility model effectively can be positioned in the groove of sheet under the mechanical three-way, in case on-slip is taken off.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the structural representation of the utility model user mode.
Embodiment
Mechanical three-way sealing gasket as depicted in figs. 1 and 2, it comprises packing ring body 1 in the form of a ring, the bottom surface of packing ring body 1 is provided with down interior ring protruding 3 and the outer shroud of stretching protruding 4, the internal diameter of interior ring protruding 3 and the identical size of internal diameter of packing ring body 1, the external diameter of outer shroud protruding 4 is littler than the external diameter of packing ring body 1, in four lead channel 5 that have been periphery on ring protruding 3 the interior facade, the space between interior ring protruding 3 and the outer shroud protruding 4 is an annular groove 2, the height of interior ring protruding 3 is less than the height of outer shroud protruding 4.The end face of packing ring body 1 is provided with ring convex tendon 7, and ring convex tendon 7 can be provided with three or two, is two shown in the figure, and the outer surface of outer shroud protruding 4 is provided with location convex tendon 6, and location convex tendon 6 can adapt with the positioning groove that is provided with in the sheet under the mechanical three-way.
Shown in Fig. 3 is the utility model user mode, be about to the sealing pad and be placed on the schematic representation that is connected in the sheet 8 under the mechanical three-way on the pressure piping 9, this moment mechanical three-way last slice with following sheet be in the pretension state, the leakage mouth 10 that the partially liq of pressure piping can be provided with on the sheet 8 under mechanical three-way enters in the annular groove 2 along lead channel 5, when continuing the sheet up and down of fastening machines threeway, ring convex tendon 7 can be close to the surface of pressure piping 9 and further be compressed, the flute surfaces of sheet 8 under the mechanical three-way is close in the bottom of interior ring protruding 3 and outer shroud protruding 4, owing to be loaded with liquid in the annular groove 2, thereby form liquid sealing.
