Description
Technical field
The utility model is related to sealing article more particularly to a kind of low slip gasket seals.
Background technology
Gasket seal, which is a kind of is placed in the joint plane of pipeline, case or discrete, prevents medium osmosis
Seal, it is therefore an objective to the medium obstructed in pipeline or device leaks out.In the sealing system comprising gasket, medium is outward
The approach of leakage can be divided into boundary leakage and body leakage, and boundary leakage is by existing gap between gasket surface and flange face
Toward external leakage, body leakage is then that medium is leaked outward by hole existing for gasket internal structure.Do not changing gasket material
Under the premise of formula, the boundary leakage for improving material can be by adding attached one very thin seal coating or Jia Yinmi in gasket surface
Line is sealed to carry out, the method for generally improving body leakage is to increase the tight ness rating of sealing material, but increase the density meeting of material
The compression performance for lowering material, has a negative impact to boundary leakage, so less than optimal way.
Utility model content
Based on described above, the purpose of this utility model is that a kind of low leakage is provided on the basis of not increasing density of material
The gasket seal of rate.
The utility model is realized by the following technical solutions：
A kind of low slip flange seal gasket, including circular body, the center of the circular body offer through-hole, institute
It states and is provided with the ring packing line concentric with the through-hole on the side surface up and down of circular body, the ring packing line is corresponding
Circular body in be equipped with the hollow compression groove consistent with the ring packing line tracking；The outer waist side of the circular body is set
There are telescopic chute, the surface of the telescopic chute to be coated with anticorrosion layer.
Further, the quantity of the ring packing line is at least two.
Further, the shape of the hollow compression groove is round either rectangle, quantity and the annular of hollow compression groove
Seal line quantity is consistent.
Further, the shape of the telescopic chute is trapezoidal.
Further, side surface is equipped with the sealing no more than ring packing line half height to the circular body up and down
Coating.The seal coating is nitrile rubber or silica gel.
Further, the inner surface of the through-hole is coated with self-lubricating layer, and the self-lubricating layer is polyimides, polyethers ether
One kind of ketone, polytetrafluoroethylene (PTFE).
Compared with prior art, the utility model has the beneficial effects that：
The utility model increases self-lubricating layer in the inner edge of ring body, is assembled convenient for the gasket seal；In annular sheet
The side surface up and down of body is additionally arranged seal coating, seal line, can increase leakproofness；By in intrinsic hollow compression groove and
The telescopic chute of ontology waist side so that this gasket seal can get larger flexible deformation, reach a preferable seal pressure, then
The secondary leakproofness for assisting increasing the product, thus greatly reduces slip.
Description of the drawings
Fig. 1 is utility model structural schematic diagram.
Specific implementation mode
The embodiments of the present invention are described in detail below, it can be by claim but the utility model is novel
It limits and the multitude of different ways of covering is implemented.
A kind of low slip flange seal gasket, including circular body 1, the center of the circular body 1 offer through-hole
2, the inner surface of the through-hole 2 is coated with self-lubricating layer 20, and the self-lubricating layer 20 is polyimides, polyether-ether-ketone, polytetrafluoro
One kind of ethylene；The ring packing line 3 concentric with the through-hole 2 is provided on the side surface up and down of the circular body 1, it is described
The quantity of ring packing line 3 is at least two；It is equipped with and the annular in 3 corresponding circular body 1 of the ring packing line
The consistent hollow compression groove 6 in 3 track of seal line；The outer waist side of the circular body 1 is equipped with telescopic chute 5, the telescopic chute 5
Surface is coated with anticorrosion layer 50.
The shape of the hollow compression groove 6 is that round either rectangle, the quantity and annular of hollow compression groove 6 are close
It is consistent to seal 3 quantity of line.
Being preferably shaped to for the telescopic chute 5 is trapezoidal, trapezoidal shape can make the compression ratio of gasket reach one it is more excellent
State.
About 1 side surface of the circular body is equipped with the seal coating 4 no more than 3 half height of ring packing line.
The seal coating 4 is nitrile rubber or silica gel.
Seal coating 4 described in this implementation can be nitrile rubber or silica gel or can fasten the elasticity that jail connects with gasket seal
One kind in colloid, applying the method for seal coating 4 can use brush to be applied in the good gasket seal inner edge of single punching press and outside
Application is smeared, can also be in advance that the good gasket seal placement of punching press is stacked, then applied to gasket inner edge and outside with spraying method
Add seal coating 4.
In the present embodiment, the gasket seal after application seal coating 4 is tested according to state's GB/T540-2008 test methods,
When experiment, gasket sample on probation is 120mm outer diameters, and the ring-like sample of 80mm internal diameters, the pressing force of oil-tight test is
30MPa, the oil medium used are ASTM #903 machine oil, and test method is filled to oil collecting pipe by experimental rig oil pump
Machine oil closes tubing valve when medium reaches scheduled pressure medium in oil collecting pipe, and the start recording time is simultaneously observed outside test piece
Edge does not find that moistening or medium outflow or exudation, conclusion are oozed for nothing such as whether there is or not leakage phenomenon is moistened after 30 minutes experiment processes
Leakage；Otherwise it is to have leakage.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
