Description of drawings
Fig. 1 is one of the structural representation of the whirl compensator of the utility model.
Fig. 2 be the utility model whirl compensator structural representation two.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Embodiment one.
Like Fig. 1, shown in 2.
A kind of explosion-proof high pressure resistant self-sealing rotary compensator; It comprises reducing outer tube 11, interior pipe 1 and explosion-proof outer shroud 7; Manage on 1 in one end of explosion-proof outer shroud 7 is sleeved on; Its other end links to each other with reducing outer tube 11; The insertion end of pipe 1 is provided with an outer convex shoulder 13 in described; Described reducing outer tube 1 and described outer convex shoulder 13 position that matches is provided with internal shoulder 12; Described outer convex shoulder 13 forms an end face seal chamber that high voltage bearing end-face seal ring 10 is installed with the outer surface of internal shoulder 12 outer corresponding interior pipes and the internal surface of reducing outer tube 11, and high pressure resistant end-face seal ring 10 can adopt Composite Material Seal Ring (can adopt the inventor to use high pressure resistant seal ring at the whirl compensator of first to file, like Chinese patent ZL200820034089.3); In described, also be equipped with at least on pipe 1 the periphery one explosion-proof in ring 4, described explosion-proof in ring 4 and explosion-proof outer shroud 7 end face and relevant surfaces or explosion-proof in ring 4 and the internal shoulder and the relevant surfaces that are connected in the explosion-proof outer shroud 7 end face seal chamber that surrounds one or several other installation end face flexible seal ring 3 jointly.Like Fig. 1, shown in 2.
Following map 1 is further described.
Among Fig. 1,2, reducing outer tube 11 is weldingly connected successively and is formed by main paragraph 101, sealing seat 9, is provided with an internal shoulder 12 on the described sealing seat 9 at least.The end setting-in that described explosion-proof outer shroud 7 links to each other with reducing outer tube 11 is fixed in the annular groove on reducing outer tube 11 surfaces.Between the outer surface of the internal surface of described reducing outer tube 1 and interior pipe, also be provided with the face seal chamber that is used for installing ring face seal circle 8, with further raising sealing.Described face seal chamber is between adjacent end face seal chamber; Described face seal circle 8 is realized axially locating through the interior step end and the sealing gland 6 of reducing outer tube 1; Sealing gland 6 is flange arrangement; This flange arrangement can link to each other (Fig. 2) through pipe 11 in connecting bolt 8 and the reducing, also can through spring 5 with explosion-proof in encircle 4 and offset, shown in Figure 1.Between the surface of contact of reducing outer tube 11 and interior pipe 1, also can be equipped with and help both balls 2 in relative rotation.In described in pipe explosion-proof on 1 ring 4 can be overall structure with interior pipe 1, the structure that also can or be weldingly connected, when adopting the structure that is weldingly connected, described explosion-proof in ring 4 best setting-ins manage in the annular groove on 1 in being weldingly fixed on.During concrete the manufacturing, from angle easy for installation, described sealing seat 9 should be designed to half slide structure with explosion-proof outer shroud 7, welds after two Hough assembly units again.
Can find out by Fig. 1,2; When the outer convex shoulder 13 on interior pipe 1 insertion end is used with the corrosion and damage fracture because of receiving alternation for a long time, thus on the interior pipe 1 another or several in first explosion-proof in ring 3 substitute playing of the outer convex shoulder 13 in ends immediately and manage the effect that 1 stressed disengaging reducing outer tube 11 causes serious security incident generation in preventing.This is the essence place of the utility model blasting resistance structure, explosion-proof in theory in the quantity of ring 3 many more, safety coefficient is big more, but that structure also correspondingly can become is more complicated, encircling 3 with one in explosion-proof during practical implementation is optimum structure.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
