The beneficial effect of technique scheme is: coordinate nail pressing plate to achieve dismountable installation of filter by reserved flange circle, meanwhile, in order to ensure its sealing, is made up the problem of the sealing caused due to screw by the sealing of multipolarity.
Accompanying drawing explanation
Fig. 1 is that the structure of the detachable Multi-level sealing structure of the present invention is analysed and observe.
Fig. 2 is the sectional view of flange circle in the present invention.
Reference numeral in figure: 100-filter, 200-cylindrical shell, 300-flange circle, 401-first sealing ring, 402-second sealing ring, 403-the 3rd sealing ring, 500-follows closely pressing plate, 600-screw, 701-first groove, 702-second groove, 703-the 3rd groove, 800-step groove.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, the embodiment of the present invention is described further.
Filter 100 for present high-pressure filteration tank is the deficiencies by directly welding existing for location, the invention provides now following technical scheme: a kind of detachable Multi-level sealing structure, comprise cylindrical shell 200, flange circle 300 and filter 100, described filter 100 is placed on flange circle 300, and on filter 100 with flange circle 300, be provided with the nail pressing plate 500 of a fixing filter 100, nail pressing plate 500 is provided with and runs through nail pressing plate 500 and the screw 600 stretched in flange circle 300, the fixing of filter 100 is realized by the structure of screw 600 and nail pressing plate 500, but owing to being fixed by screw 600, will gap be there is in that, thus have impact on its sealing effectiveness, poor by following closely its sealing effectiveness of fixed form of pressing plate 500, and for filter, sealing is one of key factor determining sealing effectiveness, so such technical scheme is not enough, but it effectively can realize the installation and removal to filter 100.
So carry out bamboo product in above-mentioned technical scheme: be provided with the first sealing ring 401 between described flange circle 300 and top pressing board, described filter 100 and flange circle 300 are provided with the second sealing ring 402 and the 3rd sealing ring 403, and the diameter of described 3rd sealing ring 402 is greater than the diameter of the second sealing ring 402.Can find with reference to accompanying drawing 1, the first sealing ring 401 is wherein in the left side of screw 600, the seepage that between anti-non-magnetic shim pressing plate 500 and flange circle 300, the gap at A place produces, and the second sealing ring 402 and the 3rd sealing ring 403 are on the right side of screw 600, prevent screw 600 produce the seepage that between the gap at C place and nail pressing plate 500 and flange circle 300, the gap at B place produces, wherein, second sealing ring 402 is first sealing, but such sealing is not absolute, so realize further sealing at increase the 3rd sealing ring 403.So just can improve its sealing greatly, and then ensure that filter effect.
Meanwhile, with reference to figure 2, described flange circle 300 is welded on the inner side of cylindrical shell 200, and being conveniently connected on flange circle 300 of filter 100 offers a step groove 800, and filter 100 is placed in step groove 800.In order to flange circle 300 internal rising improved described in its sealing effectiveness be provided with respectively with the first groove 701, second groove 702 and the 3rd groove 703 of the first sealing ring 401, second sealing ring 402 and the 3rd sealing ring 403 adaptation, and the first sealing ring 401, second sealing ring 402 and the 3rd sealing ring 403 are all tetrafluoro circle.
Achieve the connection to filter 100 by screw 600 cooperation nail pressing plate 500, this makes it possible to the installation and removal facilitating filter 100, and after filter 100 damages, can change fast, and then reduce cost, improve its serviceability; Meanwhile, by multistage hermetically-sealed construction, carry out omnibearing sealing, improve the sealing that filter 100 is connected with cylindrical shell 200, and then ensure that its filter effect.
Meanwhile, provide a kind of multi-stage sealed method being suitable for above-mentioned detachable Multi-level sealing structure, fix filter 100 by reserved flange circle 300, then filter 100 and flange circle 300 are carried out to the sealing of at least three grades by tetrafluoro circle.
The present invention is set to further: its concrete steps are as follows:
(a), reserved: first on cylindrical shell 200, weld upper flange circle 300;
(b), sealing: filter 100 is placed on flange circle 300, and between flange circle 300 and filter 100, places at least two tetrafluoro circles seal;
(c), fixing: make filter 100 and flange circle 300 compress and fix by nail pressing plate 500 attachment screw 600, and between flange circle 300 and pressure strip, place the tetrafluoro circle of at least one.
Coordinating nail pressing plate 500 to achieve dismountable installation of filter 100 by reserved flange circle 300, meanwhile, in order to ensure its sealing, being made up the problem of the sealing caused due to screw 600 by the sealing of multipolarity.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, those skilled in the art carries out common change and replaces should being included in protection scope of the present invention within the scope of technical solution of the present invention.
