Abstract
The utility model discloses a fast open -blind board of wheel thick liquid formula, it includes the skull, is equipped with interlocking device on the skull, and skull one end is equipped with slewing mechanism, and its other end is equipped with rocking arm mechanism, slewing mechanism mainly by lead screw, driving lever, dial the board and constitute, the lead screw is connected with the driving lever, the driving lever is connected with group board, group board passes through the center pin to be connected with rocking arm mechanism, set up a checkpoint in the rocking arm mechanism board and blind plate, the cardboard is connected with slewing mechanism's the board of dialling, and the blind plate is connected with the cardboard, and the outside of blind plate and cardboard is equipped with the blind plate overcoat, is equipped with sealed rubber ring between blind plate and the blind plate overcoat. The utility model discloses simple structure, rapid, the sealed safe and reliable of switch.
Description
Technical field
The utility model relates to pipeline and the storage tank fields such as oil, natural gas, chemical industry, is specifically related to the improvement of a kind of wheel paddle fast opening blind structure in pipeline and storage tank.
Background technology
Fast opening blind is the circular open for pressure pipeline and pressure vessel, a kind of mechanical device quickly opened and closed can be realized, he can quickly open and close the end cap of the bearing device such as receiving ball tube, filter, it is possible to replaces the blind flange on the pipeline or container frequently switched in oil refining, chemical industry, medical treatment, papermaking, national defence, water supply and sewage work.But currently used wheel slurry fast opening blind still suffers from many weak points technically, such as, blind plate uses the old-fashioned fast opening blind such as castellated, eye-splice-type, snap ring-type, easily produces seal and rubs mutually choosing to install to put on, seal rapid wear and be easily generated leakage, many deficiencies such as do not open for a long time in year.
Utility model content
In consideration of it, the purpose of this utility model be to provide a kind of simple in construction, switch rapidly, sealingly secure take turns paddle fast opening blind reliably.
The technical scheme that the utility model provides is: a kind of wheel paddle fast opening blind, including skull, skull is provided with interlocking mechanism, skull one end is provided with rotating mechanism, its other end is provided with whirling arm mechanism, described rotating mechanism is mainly by leading screw, driving lever, plate forms, leading screw is connected with driving lever, driving lever is connected with plate, plate is connected with whirling arm mechanism by central shaft, clamp and blind plate is set in described whirling arm mechanism, clamp is connected with the plate of rotating mechanism, blind plate is connected with clamp, the outside of blind plate and clamp is provided with blind plate overcoat, it is provided with O-ring seal between blind plate and blind plate overcoat.
Improving technical scheme further, blind plate is coaxial biplate blind plate.
The beneficial effects of the utility model are:
1, simple in construction, switch is quick: simple in construction understands, wheel hub only need to align wheel recess, with spanner rotating threaded shaft 90-720 °, it is ensured that an operator, in the case of need not any special tool(s), opens blind plate, safety, No leakage in one minute during switch；
2, coaxial double plate, translation seals: owing to fast opening blind rotating part and hermetic unit are coaxial double plate, the axially forwardly thrust that the rotation of clamp produces with its inclined-plane, promote blind plate translation displacements forward, sealing ring is made to be squeezed, thus reach translation sealing state, make seal not by any wear-out failure；
3, linkage locking, safe and reliable: to close and put in place (otherwise safety interlock for overhead cannot load), load safety interlocking, meet and can boost after all locking on scheduled operation position, otherwise can not boost；After safety interlock for overhead loads, skull cannot rotate；After system discharge, must first open safety interlock for overhead, after making container internal pressure all release, the breakdown action of skull can be carried out, otherwise cannot open skull.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and the utility model is described in further detail by embodiment:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is schematic cross-section of the present utility model.
1-rotating mechanism；2-interlocking mechanism；3-whirling arm mechanism；4-O-ring seal；5-blind plate overcoat；6-blind plate；7-clamp；11-leading screw；12-driving lever；13-plate；8-central shaft, 9-skull.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further explained, but does not limit to the utility model.
Such as Fig. 1, shown in Fig. 2, the utility model includes skull (9), skull (9) is provided with interlocking mechanism (2), skull (9) one end is provided with rotating mechanism (1), its other end is provided with whirling arm mechanism (3), described rotating mechanism (1) is main by leading screw 11, driving lever 12, plate 13 forms, leading screw 11 is connected with driving lever 12, driving lever 12 is connected with plate 13, plate 13 is connected with whirling arm mechanism (3) by central shaft 8, clamp 7 and blind plate 6 is set in described whirling arm mechanism (3), clamp 7 is connected with the plate 13 of rotating mechanism (1), blind plate 6 is connected with clamp 7, the outside of blind plate 6 and clamp 7 is provided with blind plate overcoat 5, O-ring seal 4 it is provided with between blind plate 6 and blind plate overcoat 5.
For improving technical scheme further, described blind plate can be coaxial biplate blind plate；Use coaxial biplate blind plate to form, be characterized in axially forward portion blind plate transfixion, utilized by lead screw transmission the wheel oar inclined-plane of clamp below to rotate the axially forwardly thrust produced, promote above blind plate translation squeeze sealing member, reach blind plate and close locking purpose.Thus ensure between blind plate and seal without relative motion, it is to avoid blind plate produces friction with seal, causes impaired generation of seal to be revealed.Additionally, wheel-oar type fast opening blind also has secondary pressure release and safety interlocking (shockproof, anti-loosening) function, when in cylinder also with overbottom pressure, blind plate cannot be opened, and more ensure that the security of operation.
Detailed description of the invention of the present utility model is to carry out writing according to the mode gone forward one by one, and highlights the difference of each embodiment, and its similar portion can be with cross-reference.
Above in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible on the premise of without departing from the utility model objective, various changes can be made.
