Abstract
The utility model discloses a high vacuum flange is sealed to be filled up, include the support ring of making by the polytetrafluoroethylene material, the fixed cover of outer peripheral face of support ring is equipped with 0 type circle in packet fluorine. The utility model discloses the advantage lie in with the support ring is set to by holding ring portion and is set up and is in the support ring bilge construction at holding ring portion outer peripheral face middle part to the fixed 0 type circle in the suit package fluorine of outer peripheral face in support ring portion, exert so promptly polytetrafluoroethylene have antiacid, the characteristic of alkali -resistant, exert the package fluorine O type circle characteristic that the use also can remain unchanged shape under the high voltage ring border for a long time again, satisfied the vacuum seal technological requirement, prolonged high vacuum flange is sealed to be filled up's life, has also avoided paining the vacuum silicone grease simultaneously and has maintain the not enough of high vacuum. Simultaneously, support ring portion plays the positioning action of glass flange opening when the installation of being convenient for again.
Description
Technical field
The utility model is related to sealing gasket, more particularly, to high vacuum flange sealing gasket.
Background technology
Glass apparatus is often used in the laboratories such as Rotary Evaporators, glass reaction kettle, is used for the change under normal pressure or condition of negative pressure
Reaction is learned, extracted, crystallized, and most of solvent that it is used all carries severe corrosive and highly acid.At present, for above-mentioned instrument
Sealing gasket on pipeline at adpting flange is generally polytetrafluoroethylene (PTFE) annular sealing gasket.Polytetrafluoroethylene (PTFE) has antiacid alkali resistant, resists respectively
The characteristics of planting organic solvent, is practically insoluble in all of solvent.Due to above-mentioned polytetrafluoroethylene (PTFE) annular sealing gasket for face seals, make
Used time needs to smear vacuum silicon grease on pad face to maintain high vacuum, and vacuum silicon grease has the risk of pollution, does not use vacuum
Silicone grease does not reach vacuum sealing technological requirement again, while being used under hyperbaric environment for a long time, easily deforms and reduces and use the longevity
Life.
The content of the invention
The utility model purpose is to provide a kind of high vacuum flange sealing gasket.
To achieve the above object, the utility model takes following technical proposals：
High vacuum flange sealing gasket described in the utility model, including the support ring being made up of polytetrafluoroethylmaterial material, institute
The outer peripheral face fixed cover for stating support ring is equipped with the type circle of bag fluorine 0.
The support ring is made up of positioning ring portion and the support ring portion being arranged in the middle part of the positioning ring portion outer peripheral face, described
Outer peripheral face of the type circle fixed cover of bag fluorine 0 loaded on the support ring portion, the axial direction with diameter greater than support ring portion of the type circle of bag fluorine 0 is long
Degree.
The utility model advantage is that the support ring is arranged to by positioning ring portion and is arranged on outside the positioning ring portion
The support ring portion structure of all Middle faces, and in the type circle of outer peripheral face fixation suit bag fluorine 0 of support ring portion；So play poly- four
PVF has antiacid, alkali resistant characteristic, and long-term being used under hyperbaric environment of bag fluorine O-ring has been played again also can keep constant
The characteristic of shape, meets vacuum sealing technological requirement, extends the service life of high vacuum flange sealing gasket, while it also avoid
Vacuum silicon grease is smeared to maintain the deficiency of high vacuum.Meanwhile, support ring portion is played again is easy to glass flange determining mouthful when mounted
Position effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings, the present embodiment is with the utility model technology
Implemented under premised on scheme, given detailed implementation method, but protection domain of the present utility model is not limited to following realities
Apply example.
As shown in figure 1, high vacuum flange sealing gasket described in the utility model, including be made up of polytetrafluoroethylmaterial material
Support ring, the support ring is made up of positioning ring portion 1 and the support ring portion 2 being arranged in the middle part of the positioning outer peripheral face of ring portion 1, in support
The outer peripheral face fixed cover of ring portion 2 is equipped with the type circle 3 of bag fluorine 0, the axial length with diameter greater than support ring portion 2 of the type circle 3 of bag fluorine 0.
Claims (2)
