Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1, it is structural representation of the present utility model, a kind of fluid circuit seal connection of the utility model, comprise inner sleeve 1, outer sleeve 2, guidance tape 3 and seal ring 4, described inner sleeve 1 and outer sleeve 2 are the structure that boss 1a, 2a acting flange dish 1b, 2b meet hollow shaft 1c, 2c, and boss 1a, 2a and flange plate 1b, 2b center establish through hole to connect with hollow axis hole; Outer sleeve 2 hollow shaft 2c internal surface can slide axially along inner sleeve 1 hollow shaft 1c outer surface, and inner sleeve 1 establishes guidance tape 3 and seal ring 4 on the outer surface coordinated with outer sleeve 2; Boss 1a, 2a outer round surface of inner sleeve 1 and outer sleeve 2 is equipped with seal ring 4.
Adopt Spielpassung between described inner sleeve 1 and the slip surface of outer sleeve 2, and the surface roughness after processing is Ra12.5 ~ Ra6.3.
Described inner sleeve 1 and outer sleeve 2 matching surface at least establish 2 guidance tapes 3 and 1 seal ring 4, and seal ring 4 is between guidance tape 3.
Described seal ring 4 is O RunddichtringO.
The effect of guidance tape 3 makes can slide smoothly between inner sleeve 1, outer sleeve 2, and seal ring 4 plays axial seal effect, makes to have sealing function between inner sleeve 1 and outer sleeve 2.During use, boss 1a, 2a of inner sleeve 1, outer sleeve 2 outside stretch into the adpting flange that matches or pipe joint inside coordinates with its internal surface, and plays axial seal effect by seal ring 4 equally.
Following examples are implemented under premised on technical solutions of the utility model, give detailed mode of execution and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1] sees Fig. 2, is a kind of embody rule example of a kind of fluid circuit of the utility model seal connection, adopts a kind of fluid circuit seal connection of welding type adpting flange 5 and the utility model to be connected in the present embodiment.Boss 1a, 2a of inner sleeve 1 and outer sleeve 2 stretch in the endoporus of both sides adpting flange 5 respectively, the matching surface of inner sleeve 1 boss 1a and adpting flange 5 and outer sleeve 2 boss 2a and adpting flange 5 is equipped with seal ring 4, between inner and outer sleeves 1,2 and flange 5, plays axial seal effect; Seal ring 4 on inner sleeve hollow shaft 1c plays axial seal effect between inner sleeve 1 and outer sleeve 2.
The both sides of connecting screw rod 6 are each passed through flange plate 1b, 2b of adpting flange 5 and inner and outer sleeves 1,2, use respectively outside adpting flange, inside the flange plate 1b of inner sleeve and inside the flange plate 2b of outer sleeve attaching nut 7,8,9,10 fastening, screw rod 6 and nut 7,8 coordinate and are used for clamp flange 5 and inner sleeve 1; Screw rod 6 and nut 9,10 cooperation are used for being fastenedly connected flange 5 and outer sleeve 2, and namely axial sealer and adpting flange 5 realize being tightly connected.
When being arranged on pipeline, should note making inside inner sleeve 1 flange plate 1b with outer sleeve 2 flange plate 2b inside spacing be greater than the length sum of inner and outer sleeves boss 1a, 2a, to facilitate taking-up seal connection; The process of taking out seal connection is: first the pressure medium of confirmation connecting pipeline inside is zero, then nut 7,8,9,10 and screw rod 6 is dismantled, keep the relative position of adpting flange 5 constant, inner sleeve 1 and outer sleeve 2 are slided all to the inside, seal connection can be taken out when boss 1a, 2a end face shifts out adpting flange 5 end face, then integral replacing or change seal ring 4 and guidance tape 3; If only change the seal ring 4 at both sides boss 1a, 2a and adpting flange 5 place, then only need to unclamp nut 8,9, inner sleeve 1 and outer sleeve 2 are slided to the inside, changes after exposing seal ring 4, do not need dismantling screw 6 and nut 7,10.
The face that is sealed and matched between inner and outer sleeves 1,2 and the face that the is sealed and matched machining accuracy between inner and outer sleeves 1,2 and adpting flange 5 are Ra12.5 ~ Ra6.3, will ensure coaxality after installation; The wall thickness at inner and outer sleeves 1,2 hollow shaft 1c, 2c place needs design by actual strength.
When connecting screw rod 6 under fluid pressure action to two side stretchings time, inner and outer sleeves 1,2 moves respectively to both sides under fluid forces simultaneously, and inner and outer sleeves 1,2 and adpting flange 5 ensure close contact all the time, thus ensure that the sealing of connection.
