Abstract
The utility model relates to flange gasket positioning device technical field, and be a kind of automatic-positioning type flange gasket, it comprises pad and soft metal layer; Be installed with a circle soft metal layer at the excircle of pad, soft metal layer is provided with the concentrically ringed circular line of cut with soft metal layer.The utility model reasonable and compact in structure, easy to use, when mounted, the circumferential size that only need surround according to bolt on flange, circular line of cut along a circle circle peels off soft metal layer periphery redundance, in the external diameter of remaining soft metal layer is just in time stuck in circumference that bolt surrounds, does not need manually to adjust position, be easy to, just by pad centering, there will not be the phenomenon of pad sideslip.
Description
Technical field
the utility model relates to flange gasket positioning device technical field, is a kind of automatic-positioning type flange gasket.
Background technique
metal wound gasket is widely used in the sealing between flange plate, and the specification of pad common at present mainly pressing force grade and internal diameter carries out dividing.When pad being installed between two flanges, if pad and flange do not have centering, poorly sealed possibly.Before and after overwhelming majority flowmeter flow meter, straight length has requirement, if flange gasket does not have centering before and after flowmeter, will produce choked flow, cause fluids within pipes fluidised form to change, metering also just loses degree of accuracy.The method making flange gasket centering commonly use at present is exactly the distance of range estimation pad external diameter and flange, adjustment is gone with the oblong objecies such as the bottle opener gap filled between two flanges, troublesome poeration, and it is very hard to be in course of adjustment, if what bolt was twisted too tightly cannot move pad, if the too pine that bolt is twisted, pad is easily run chaotically, and cannot fix.
Summary of the invention
the utility model provides a kind of automatic-positioning type flange gasket, overcomes the deficiency of above-mentioned prior art, and it effectively can solve the problem that current flange gasket is not easy centering.
the technical solution of the utility model is realized by following measures: a kind of automatic-positioning type flange gasket, comprises pad and soft metal layer; Be installed with a circle soft metal layer at the excircle of pad, soft metal layer is provided with the concentrically ringed circular line of cut with soft metal layer.
here is the further optimization and/or improvements to above-mentioned model utility technological scheme:
the above-mentioned cylindrical at pad is suppressed with a circle soft metal layer.
the thickness of above-mentioned soft metal layer is 0.1mm.
above-mentioned soft metal layer is flake aluminum layer.
above-mentionedly on soft metal layer, 1 millimeter is provided with the concentrically ringed circular line of cut with soft metal layer.
the utility model reasonable and compact in structure, easy to use, when mounted, the circumferential size that only need surround according to bolt on flange, circular line of cut along a circle circle peels off soft metal layer periphery redundance, in the external diameter of remaining soft metal layer is just in time stuck in circumference that bolt surrounds, does not need manually to adjust position, be easy to, just by pad centering, there will not be the phenomenon of pad sideslip.
Accompanying drawing explanation
accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.
accompanying drawing 2 is main TV structure schematic diagram when the utility model is arranged on flange.
coding in accompanying drawing is respectively: 1 is pad, and 2 is soft metal layer, and 3 is circular line of cut, and 4 is flange, and 5 is bolt.
Embodiment
the utility model by the restriction of following embodiment, can not determine concrete mode of execution according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2, this automatic-positioning type flange gasket comprises pad 1 and soft metal layer 2; Be installed with a circle soft metal layer 2 at the excircle of pad 1, soft metal layer 2 is provided with the concentrically ringed circular line of cut 3 with soft metal layer 2.When using pad 1, according to the circumference that the bolt 5 on flange 4 surrounds, circular line of cut 3 along a circle circle peels off soft metal layer periphery redundance, in the external diameter of remaining soft metal layer 2 is just in time stuck in circumference that bolt 5 surrounds, now, pad 1 and flange 4 concentricity are consistent, and reach the object of pad 1 centering.Adopt automatic-positioning type flange gasket of the present utility model, when mounted, do not need manually to adjust position, be easy to, just by pad 1 centering, there will not be the phenomenon of pad 1 sideslip.
according to actual needs, above-mentioned automatic-positioning type flange gasket can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2, be suppressed with a circle soft metal layer 2 at the cylindrical of pad 1.
as shown in accompanying drawing 1,2, the thickness of soft metal layer 2 is 0.1mm.According to actual needs, the thickness of soft metal layer 2 only need be designed to be less than pad 1 thickness with pad 1 stack pile or thickness.Usually, according to the thickness of conventional pad 1, soft metal layer 2 is designed to 0.1mm can achieve the goal.
as shown in accompanying drawing 1,2, soft metal layer 2 is flake aluminum layer.
as shown in accompanying drawing 1,2, soft metal layer 2 is provided with the concentrically ringed circular line of cut 3 with soft metal layer 2 every 1 millimeter.Circular line of cut 3 is by every 1 millimeter of setting, and most convenient during use, effect is also best.
above technical characteristics constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristics according to actual needs, meet the demand of different situations.
