Abstract
The invention discloses a sealing gasket, which is used for mechanical seal of a glass lined reactor. The sealing gasket is a polytetrafluoroethylene ring gasket; a tooth-shaped connecting nick is formed on the polytetrafluoroethylene ring gasket; the sealing gasket is fastened at the connecting nick; and the inner diameter and outer diameter of a ring of the sealing gasket are set according to dimension of the mechanical seal of the glass lined reactor. By the polytetrafluoroethylene sealing gasket for mechanical seal of the glass lined reactor, workload of maintaining and repairing equipment can be reduced, and the yield is improved; and because the sealing performance is high, air pollution is reduced.
Description
Technical field
The present invention relates to the chemical industry equipment field, in particular a kind of sealing gasket that is used for glassed steel reaction vessels mechanical seal.
Background technique
The material of glassed steel reaction vessels production belongs to the medium of deep-etching and high-temperature, as shown in Figure 1, thereby the easy deliquescing distortion under the environment of deep-etching, High Temperature High Pressure of traditional tetrafluoro asbestos seal pad loses seal action, make air in the exhaust emission pollution workshop that produces in the reactor, particularly be subjected to machine oil in the mechanical seal food tray and overflow the damage of accelerating the tetrafluoro asbestos behind the infiltration sealing gasket especially.Lack and need separate stirrer and could change sealing gasket the working life of this type of sealing gasket, and labor intensity is big, also has a strong impact on production.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of sealing gasket that is used for glassed steel reaction vessels mechanical seal, be intended to the problem that solves existing tetrafluoro asbestos seal pad weak point in working life, changes trouble.
Technological scheme of the present invention is as follows:
A kind of sealing gasket, be used for glassed steel reaction vessels mechanical seal, wherein, described sealing gasket is a teflon ring pad, also be provided with the connection breach of a dentation on teflon ring pad, described sealing gasket fastens mutually in described connection indentation, there; Described sealing gasket is provided with the internal diameter and the external diameter of its ring according to the size of glassed steel reaction vessels mechanical seal.
Described sealing gasket, wherein, the connection breach of described dentation is the helical teeth shape.
Described sealing gasket, wherein, the radial section that described helical teeth shape connects breach and sealing gasket forms 45-50 degree angle.
Described sealing gasket, wherein, described sealing gasket is provided with the internal diameter and the external diameter of teflon ring pad according to the size of glassed steel reaction vessels mechanical seal.
Described sealing gasket, wherein, the thickness of described sealing gasket is 8mm-10mm.
Beneficial effect: the workload of using the polytetrafluoroethylene sealing gasket that is used for glassed steel reaction vessels mechanical seal of the present invention can reduce device maintenance, maintenance improves output simultaneously, because favorable sealing property also reduces the pollution to air.
Description of drawings
Fig. 1 is the structural representation of traditional sealing gasket.
Fig. 2 is the structural representation of polytetrafluoroethylene sealing gasket of the present invention.
Embodiment
The invention provides a kind of sealing gasket that is used for glassed steel reaction vessels mechanical seal, clearer, clear and definite for making purpose of the present invention, technological scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Because the teflon material has the following advantages: high temperature resistant---use operating temperature to reach 200 ℃; Corrosion-resistant---to most of chemicalss and solvent, show inertia, energy strong alkali-acid resistance, water and various organic solvent; Weatherability---aging life-span best in the plastics is arranged; High lubricated---be friction factor the lowest in the solid material.Therefore the sealing gasket made from polytetrafluoroethylmaterial material can still keep good sealing property and working life longer than general tetrafluoro asbestos seal pad under the environment of deep-etching, High Temperature High Pressure.
The sealing gasket that is used for glassed steel reaction vessels mechanical seal provided by the present invention is to be made by teflon, its structure as shown in Figure 2, internal diameter of size processing according to mechanical seal is that D1 and external diameter are the suitable teflon plectane ring pad of D2, about the about 8mm-10mm of thickness, again teflon plectane ring pad is sawed out the dentation that can fasten with wire saw and connect breach 3, described connection breach can fasten mutually; Because adopted the connection breach of dentation, the function of its sealing just can be guaranteed, even after being under pressure or working a period of time, the effect of this sealing can be maintained.Simultaneously, owing to can need not to take apart stirrer, can install the polytetrafluoroethylene sealing gasket with connection breach 3, as long as upwards mention after the dynamic and static ring whole bundle of mechanical seal unclamped and reserve a little space, polytetrafluoroethylene sealing gasket was overlapped stirrer from connecting breach 3, revert to original complete circular plate shape with the tetrafluoro raw meal belt do simple dressing again, mechanical seal is finished by dress by the anti-order of taking apart gets final product then.
The polytetrafluoroethylene sealing gasket that is used for glassed steel reaction vessels mechanical seal provided by the present invention has been done an improvement: with the breach of a dentation of teflon plectane ring pad saw, can need not to take apart under the situation of stirrer and change sealing gasket, the connection breach 3 of dentation plays the effect of mutual fastening, is to break through sealing gasket and design in order to prevent that internal pressure is too high.
Further, the breach of the dentation of the polytetrafluoroethylene sealing gasket that is used for glassed steel reaction vessels mechanical seal provided by the present invention is a helical teeth shape breach, as shown in Figure 2, the angle β that its dentation connects the radial section formation of breach 3 and polytetrafluoroethylene sealing gasket is the 45-50 degree, the good technique effect of the dentation breach of this gradient is not for can being convenient to the installation of sealing gasket simultaneously because of breaking through sealing gasket under the effect of reactor maximum working (operation) pressure (MWP) yet.
The polytetrafluoroethylene sealing gasket that the present invention is used for glassed steel reaction vessels mechanical seal can also be used for the sealing gasket of temperature sleeve pipe.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection domain of claims of the present invention.
