Abstract
The utility model relates to a closing plate, its characterized in that: including metal sheet (1) that lies in the intermediate level, last graphite layer (2) of pasting side surface on metal sheet (1), lower graphite layer (3) of pasting side surface under metal sheet (1), paste in last graphite layer (2) on the side surface and expand teflon plate (4) on, paste the lower inflation teflon plate (5) of graphite layer (3) time side surface under in. Compared with the prior art, the utility model has the advantages of: the metal sheet in intermediate level provides closing plate's intensity, closing plate's application temperature and very fast heat dissipation are improved to the graphite layer from top to bottom, and the teflon plate that expands from top to bottom prevents droing of graphite layer, the various chemical media of ability again. This closing plate can cut into various required shapes and size, as seal gasket, can satisfy the sealed occasion of singly planting the material and can not satisfy.
Description
Technical field
The utility model relates to a kind of sealing plate.
Background technique
Teflon (English abbreviation is PTFE, and Chinese is called for short tetrafluoro), be commonly called as King, PH:0 ~ 14, the chemical mediator that almost ability is all, the high temperature of ability 260 degrees Celsius, is widely used in field of sealing technology again.General density is 2.1 ~ 2.3g/cm
3tetrafluoro plate, be often called tetrafluoro hardboard, the gasket seal compression resilience adopting this tetrafluoro plate directly to carry out cutting is poor, is not suitable for the place that flange formation degree is poor.In addition due to the cold flow characteristic of tetrafluoro, in the place that temperature alternating is violent, tetrafluoro plate can embrittlement hardening, thus cause and seal unsuccessfully.Therefore, people develop again expansion tetrafluoro plate, and density is 0.7 ~ 0.9g/cm
3, expansion tetrafluoro plate soft compressible, is easy to the pad directly cutting into various shape, is applicable to the place that flanged surface is not too smooth, and expansion tetrafluoro plate overcomes the characteristic of tetrafluoro cold flow, thus serves good sealability.But intensity and the compression resistance of expansion tetrafluoro plate are more far short of what is expected again than tetrafluoro hardboard, can not be applied to the place that pressure is relatively high, and thermal diffusivity are poor.
Model utility content
Technical problem to be solved in the utility model provides for above-mentioned prior art the resistance to acids and bases that a kind of intensity is high, thermal diffusivity good, had, the sealing plate of heat-resisting quantity.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of sealing plate, is characterized in that: comprise the sheet metal being positioned at mesosphere, is affixed on the upper graphite layer of sheet metal uper side surface, is affixed on the lower graphite layer of sheet metal downside surface; Be affixed on the upper expansion tetrafluoro plate of graphite layer uper side surface, be affixed on the lower expansion tetrafluoro plate of lower graphite layer downside surface.
Described sheet metal is metal plate or metal tooth plate.
The thickness of described sheet metal is 0.5 ~ 2mm.
The thickness of described upper graphite layer and lower graphite layer is 1 ~ 3mm.
The thickness of described upper expansion tetrafluoro plate and lower expansion tetrafluoro plate is 0.5 ~ 1.5mm.
Compared with prior art, the utility model has the advantage of: the sheet metal in mesosphere provide sealing plate intensity; Upper and lower graphite layer improve sealing plate serviceability temperature and dispelling the heat faster, expansion tetrafluoro plate prevents coming off of graphite layer up and down, again the various chemical mediator of ability.Sealing plate can cut into various required shape and size, as gasket seal, can meet the unappeasable sealing occasion of single material.
Accompanying drawing explanation
Fig. 1 be in the utility model embodiment sealing plate sectional view.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Sealing plate as shown in Figure 1: comprise the sheet metal 1 being positioned at mesosphere, be affixed on the upper graphite layer 2 of sheet metal (1) uper side surface, be affixed on the lower graphite layer 3 of sheet metal 1 downside surface; Be affixed on the upper expansion tetrafluoro plate 4 of graphite layer 2 uper side surface, be affixed on the lower expansion tetrafluoro plate 5 of lower graphite layer 3 downside surface.
Wherein, described sheet metal can adopt metal plate or metal tooth plate, the thickness range of choices of sheet metal 1 is 0.5 ~ 2mm, and the thickness range of choices of upper graphite layer 2 and lower graphite layer 3 is 1 ~ 3mm, and the thickness range of choices of upper expansion tetrafluoro plate 4 and lower expansion tetrafluoro plate 5 is 0.5 ~ 1.5mm; In the present embodiment, sheet metal 1 adopts metal plate, and thickness is 0.7mm, the equal 2mm of thickness of upper graphite layer 2 and lower graphite layer 3, and the thickness of upper expansion tetrafluoro plate 4 and lower expansion tetrafluoro plate 5 is 0.6mm.
Claims (5)
1. a sealing plate, it is characterized in that: comprise the sheet metal (1) being positioned at mesosphere, be affixed on the upper graphite layer (2) of sheet metal (1) uper side surface, be affixed on the lower graphite layer (3) of sheet metal (1) downside surface; Be affixed on the upper expansion tetrafluoro plate (4) of graphite layer (2) uper side surface, be affixed on the lower expansion tetrafluoro plate (5) of lower graphite layer (3) downside surface.
2. sealing plate according to claim 1, is characterized in that: described sheet metal (1) is metal plate or metal tooth plate.
3. sealing plate according to claim 1, is characterized in that: the thickness of described sheet metal (1) is 0.5 ~ 2mm.
4. sealing plate according to claim 1, is characterized in that: the thickness of described upper graphite layer (2) and lower graphite layer (3) is 1 ~ 3mm.
