A kind of novel precise formula of the present invention high pressure resistant rotary compensator assembly program:
The first step, multiple layer metal is wound around sealing gasket 14 and is placed in reducer pipe on cushion cap B15, then the specified position then will be screwed into pipe in outer screw thread 9 inside reducer pipe 8, and make an end face of the convex outer shroud 13 of interior pipe link closely metal be wound around sealing gasket 14, now define metal machinery sealing configuration;
Second step, Multi-layer graphite Sealing 12 is embedded by reducer pipe 8 by the inner side of reducer pipe flange 5 end and interior pipe 9 outer shroud jointly formed with in the groove of tapering, then being exerted pressure to graphite seal 12 by oil hydraulic press makes the exterior edge face of the outer ring surface of the inner side surface of graphite seal 12 and reducer pipe 8 and interior pipe 9 and the convex outer shroud 13 of interior pipe form close contact state, then the Sealing supported flange 4 of 2 1/2nd round L shapes is anchored to respectively the outer end of reducer pipe flange 5 from interior pipe 9 outer end cover, and make Sealing supported flange 4L type casting die end face (L shape short end) be tight against graphite seal 12,
3rd step, N number of steel ball 10 is placed in the groove inside outer press cover flange 11 respectively, then outer press cover flange 11 cover with steel ball 10 is anchored to the outer end of seal gland flange 4, then by N number of stud bolt 1, nut A2 and nut B7 outer press cover flange 11 and seal gland flange 4 and reducer pipe flange 5 are linked closely link fixing, comprise between both nut A2 and outer press cover flange 11 end face and put butterfly spring A3, butterfly spring B6 is put between both nut B7 and reducer pipe flange 5 end face, the L shape casting die end of seal gland flange 4 is linked closely graphite seal 12, now define again one flexible graphite packing sealing configuration.Particularly reducer pipe 8 leans on the inner side surface of reducer pipe flange 5 one end to be provided with the outer splayed shape of certain taper, and this makes the sealing effect of graphite seal 12 obtain further raising.
Such structural feature is:
1. reducer pipe to comprise in the reducer pipe that is wholely set cushion cap B and reducer pipe flange in cushion cap A and reducer pipe and is the single piece that fine finishing makes, and his rigidity and safety reliability obtain further raising.(the structure of unlike original all whirl compensators, reducer pipe and outer sleeve are by being welded to connect all-in-one-piece when assembling).
2. in, the inner outer shroud of pipe and reducer pipe inside middle portion have employed fine thread bell and spigot frame form, such structure avoids the direct impact of pressure medium to sealing material, and pressure medium is seeped into metal to be wound around the pressure at sealing gasket place almost nil after N number of accurate thread curve, why also can say that the working life that metal is wound around sealing gasket obtains further raising.
The setting of splay flexible graphite packing sealing, makes the reliability of this product sealing effect obtain abundant guarantee.
