Description
Technical field
Field of heat exchangers is the utility model is related to, more particularly, to a kind of plate type heat exchanger sealing gasket.
Background technology
The surrounding of plate type heat exchanger needs to be sealed by sealing gasket, and by the overlapping compression such as framework.But board-like change
Hot device is during use, and because the temperature in heat exchanger can constantly change, therefore sealing gasket bears the temperature difference for a long time
It after change, can decline its overall sealing performance, so as to cause fluid leakage or interior leakage.
And for the ease of installation, existing sealing gasket would generally set keeper on the outside of it, but when the keeper is long
Between may be worn after use, can also influence the sealing of sealing gasket.
Utility model content
The utility model is above-mentioned in order to overcome the shortcomings of, there is provided a kind of sealing property keeps good and board-like changed for a long time
Hot device sealing gasket, include the sealing pad body 1 of annular, be arranged with corner apertures 2 in the left and right sides of sealing pad body 1, sealing
The outside spacers of pad body 1 are provided with some keepers 3, and the sealing pad body 1 includes wear-resisting inner core 4, in the wear-resisting outsourcing of inner core 4
Thermoplastic top layer 5 is wrapped with, keeper 3 is structure as a whole with wear-resisting inner core 4, and passes outside thermoplastic top layer 5.
The utility model plate type heat exchanger sealing gasket, keeper 3 are passed behind thermoplastic top layer 5 in a ring.
The utility model plate type heat exchanger sealing gasket, the wear-resisting inner core 4 and keeper 3 are nitrile rubber, oil resistivity pole
Good, wearability is higher, and heat resistance is preferable, and bonding force is strong.Thermoplastic top layer 5 is polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) has excellent
Chemical stability, corrosion resistance, sealing, high lubrication non-stick, electrical insulating property and good anti-aging endurance.
The beneficial effects of the utility model are：
In the utility model in wear-resisting inner core outer wrapping one layer of thermoplastic top layer, thermoplasticity is good, and sealing property is protected for a long time
Hold well, and keeper and the wear-resisting inner core of inside are structure as a whole, not only abrasion resistant effect is good, and structure is more stable.That is,
The utility model is easy to install, and remains able to have good sealing after long-time use.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is the internal structure schematic diagram for sealing pad body.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Plate type heat exchanger sealing gasket as shown in Figure 1, include the sealing pad body 1 of annular, in the left and right of sealing pad body 1
Both sides are arranged with corner apertures 2, and some keepers 3 are provided with the outside spacers of sealing pad body 1.As shown in Fig. 2 the sealing gasket
Body 1 includes wear-resisting inner core 4, and thermoplastic top layer 5 is wrapped with wear-resisting inner core 4, and keeper 3 is structure as a whole with wear-resisting inner core 4,
And pass outside thermoplastic top layer 5, keeper 3 is passed behind thermoplastic top layer 5 in a ring.In wear-resisting inner core outer wrapping in the utility model
One layer of thermoplastic top layer, thermoplasticity is good, and sealing property keeps good for a long time, and keeper is integrated knot with internal wear-resisting inner core
Structure, not only abrasion resistant effect is good, and structure is more stable.That is, the utility model is easy to install, and after long-time use still
There can be good sealing.
Above-mentioned wear-resisting inner core 4 and keeper 3 are nitrile rubber, and not only wearability is higher, and oil resistivity is fabulous, heat resistance
Preferably, bonding force is strong.Thermoplastic top layer 5 is polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) also has excellent chemical stability, corrosion-resistant
Property, sealing, high lubrication non-stick, electrical insulating property and good anti-aging endurance, for also can with corrosive fluid
Play good sealing effectiveness.
In addition, cavity can be also opened in wear-resisting inner core and fill the fillers such as asbestos come make inner core keep preferably it is wear-resisting,
While heat resistance, suitably strengthen the hardness of its inner core.
Above-mentioned foundation the utility model is enlightenment, and by above-mentioned description, relevant staff completely can be not
In the range of deviateing this item utility model technological thought, various changes and amendments are carried out.This item utility model it is technical
Scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
