Embodiment
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of heat insulation pipe joint structure described in the utility model, comprise bullet pad 1, end cap 2, pipe box 3, seal ring A4, seal ring B5 and interior tube body 8, described end cap 2 is flexibly connected with interior tube body 8, seal ring A4, pipe box 3 and bullet pad 1 are installed successively between interior tube body 8 and end cap 2, described seal ring B5 is positioned on the step end face of interior tube body 8 inside, be fixed by end cap 2, described seal ring A4 is bowl-type rubber seal, and described bullet pad 1 is stainless steel; Be provided with thermal insulation layer 7 outside described interior tube body 8, the material of thermal insulation layer 7 is urethane foam, surrounds cavity 6 between described thermal insulation layer 7 and interior tube body 8, and interior tube body 8 is outer is also provided with outer tube body 9; Described end cap 2 is threaded connection with interior tube body 8, and outer tube body is just in time fixed by the end cap 2 at two ends, moving axially of restriction outer tube body.
Seal ring C10 is provided with between described outer tube body 9 and end cap 2, to seal the connecting sewing between outer tube body 9 and end cap 2, outside liquid and impurity is avoided to enter in outer tube body 9, affect pipe fitting heat insulation effect, described seal ring C10 is rubber o-ring, in seal ring C10 installation place, outer tube body 9 end face and end cap 2 end face are all processed with arc mounting groove, for the position of fixed seal ring C10.
Described outer tube body 9 inwall is provided with radial strip bulge structure 901, described interior tube body 8 liang greatly end outer wall is provided with the groove structure 801 corresponding with outer tube body 9 protruding structure 901, protruding structure 901 on outer tube body 9 inwall combines with the groove structure 801 on interior tube body 8, prevent outer tube body 9 and interior tube body 8 from relatively rotating and skidding, causing cannot dismounting end cap 2; Meanwhile, the protruding structure 901 in stage casing is just in time positioned at thermal insulation layer 7 and adds the structural joint place stayed man-hour, is filled with the space that thermal insulation layer 7 structural joint is recessed.
During Product Assembly, first thermal insulation layer 7 is wrapping on the concave surface in interior tube body 8 stage casing, the tension of thermal insulation layer 7 two ends is bonding, the groove structure 801 that cemented side seam and interior tube body 8 liang are held greatly is just to forming straight line, the groove structure 801 that the protruding structure 901 1 of outer tube body 9 rectifies internal body one end is set on interior tube body 8, protruding structure 901 in outer tube body 9, simultaneously by the connecting sewing place of thermal insulation layer 7, is filled up sinking of connecting sewing place, and is fixed by thermal insulation layer 7; Then seal ring B5 is installed on two ends, the stage casing step end face in interior tube body 8, then be arranged on port first order step outwardly by uncovered for seal ring A4, pipe box 3 is installed again, seal ring A4 pushes down by pipe box 3, prevent it from moving axially, in pipe box 3 outer end, bullet pad 1 is installed, the shell fragment of bullet pad 1 inner ring all tilts to interior tube body 8 internal direction, finally end cap 2 is connected fastening with interior tube body 8 port, realize bullet pad 1 axially locating, realize the axial restraint of outer tube body 9 and the sealing at connecting sewing place, outer tube body 9 two ends simultaneously, complete pipe fitting assembling.
When pipe 11 is installed, as shown in Figure 5, directly by pipe 11 one end from end cap 2 center hole inserting pipe elements, until pipe 7 end face is close to seal ring B5 end face, now, the seal ring B5 in pipe 11 end face and interior tube body 8 between step end face forms first and seals; Meanwhile, seal ring A4 struts by pipe 11, and pipe 11 outer wall and seal ring A4 fit, and forms second sealing; And the shell fragment of bullet pad 1 inner ring is also pushed open by pipe 11, shell fragment, by unidirectional for pipe 11 clamping, reaches the effect of retaining, and pipe 11 is not easily got loose; During dismounting pipe 11, only end cap 2 need be backed out, taken out from interior tube body 8 by pipe 11, now bullet pad 1, pipe box 3 and seal ring A4 can be enclosed within pipe 11 outer wall and together be taken out, and seal ring A4, pipe box 3 and bullet pad 1 are carefully taken off successively.
