Description
Technical field
The utility model is related to wound gasket technical field more particularly to a kind of metal wound gaskets.
Background technology
Metal wound gasket using carbon steel, the inner ring that the materials such as 304,316 are gasket, is running into strong acid in the production process
Easy burn into be easy to cause leakage during highly basic, so as to cause industrial accident is caused；Existing metal wound gasket inner ring is card simultaneously
On outer shroud, after usage time is long, interior annular strain easily comes off from outer shroud, it is impossible to reuse；It is and existing
Metal wound gasket do not possess pretensioning effect.
Utility model content
The purpose of this utility model is that easy burn into service life is short, it is pre- not possess in order to solve to exist in the prior art
The shortcomings that tight effect, and a kind of metal wound gasket proposed.
To achieve these goals, the utility model employs following technical solution：
A kind of metal wound gasket is designed, including outer shroud, the end face of described outer shroud one end along the circumferential direction offers mounting groove,
Inner ring is equipped in the mounting groove, the inner ring includes nitrile rubber layer, and the surface spraying of the nitrile rubber layer has polytetrafluoro
Pvdf layer, the one side of the nitrile rubber layer away from polytetrafluoroethylene ethylene layer is along the circumferential direction equidistant to be vertically connected with multiple connections
Bar, the connecting rod are inserted into inside limiting slot, and the limiting slot is opened on the outer shroud of connecting rod opposite position, described
Limiting slot inner horizontal and buffer stopper being slidably fitted with, buffer stopper is run through in the one end of the connecting rod away from nitrile rubber layer, and
Limiting plate is vertically connected in the connecting rod at the buffer stopper both ends.
Preferably, the outer shroud is made of stainless steel, and the end face of the outer shroud offers anti-skid chequer, among the outer shroud
The edge of through hole is arc transition side.
Preferably, the limiting slot is set for " ten " font.
Preferably, the buffer stopper is damping rubber block.
Preferably, the nitrile rubber layer, connecting rod and limiting plate are structure as a whole.
Preferably, the end face of the inner ring is higher than the end face of outer shroud.
The utility model proposes a kind of metal wound gasket, advantageous effect is：Pass through buffer stopper, connecting rod and limiting plate
Make closely to connect between outer shroud and inner ring, simultaneous buffering block has preferable resilience and restoring force, enhances the sealing of gasket
Effect.The utility model, it is simple in structure, it is corrosion-resistant, resistance to acid and alkali is strong, good airproof performance, while there is good pretensioning effect, have
The safety in utilization for improving gasket of effect.
Description of the drawings
Fig. 1 be the utility model proposes a kind of metal wound gasket structure diagram；
Fig. 2 be the utility model proposes a kind of metal wound gasket outer shroud and inner ring attachment structure schematic diagram.
In figure：Outer shroud 1, anti-skid chequer 2, mounting groove 3, inner ring 4, nitrile rubber layer 5, limiting slot 6, buffer stopper 7, connecting rod 8,
Limiting plate 9, polytetrafluoroethylene ethylene layer 10.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-2, a kind of metal wound gasket, including outer shroud 1, outer shroud 1 is made of stainless steel, and the end face of outer shroud 1 is opened
Equipped with anti-skid chequer 2, the edge of 1 intermediate throughholes of outer shroud is arc transition side, and the end face of 1 one end of outer shroud along the circumferential direction offers peace
Tankage 3, mounting groove 3 is interior to be equipped with inner ring 4, and inner ring 4 includes nitrile rubber layer 5, and the surface spraying of nitrile rubber layer 5 has polytetrafluoroethyl-ne
Alkene layer 10, the end face of inner ring 4 are higher than the end face of outer shroud 1；Anti-skid chequer 2 can increase the frictional force between fixing piece；Butyronitrile rubber
Glue-line 5 has good oil resistivity, wearability and heat resistance, while bonding force is strong；Polytetrafluoroethylene ethylene layer 10 has preferable resistance to
Burn into acid and alkali-resistance, and it is of low cost, the performance and service life of inner ring are effectively raised, while enhances use
Security.
One side of the nitrile rubber layer 5 away from polytetrafluoroethylene ethylene layer 10 is along the circumferential direction equidistant to be vertically connected with multiple connections
Bar 8, connecting rod 8 are inserted into inside limiting slot 6, and limiting slot 6 is opened on the outer shroud 1 of 8 opposite position of connecting rod, in limiting slot
6 inner horizontals and buffer stopper 7 is slidably fitted with, buffer stopper 7 is damping rubber block, and limiting slot 6 is the setting of " ten " font, connecting rod
Buffer stopper 7 is run through in 8 one end away from nitrile rubber layer 5, and is vertically connected with limiting plate in the connecting rod 8 at 7 both ends of buffer stopper
9, nitrile rubber layer 5, connecting rod 8 and limiting plate 9 are structure as a whole；Fixing piece can squeeze buffer stopper 7 when fixed,
Buffer stopper 7 is in compressive state；Fixing piece passes through much time using, it may appear that loose phenomenon when fixing piece loosens, is delayed
Rushing block 7 can slowly reset, and it is not in always leakage phenomenon in sealing state to make inner ring 4.
Embodiment：Fixing piece squeezes buffer stopper 7 when fixed, and buffer stopper 7 is in compressive state, works as fixing piece
When generating loosening, buffer stopper 7 slowly resets, and plays good pretensioning effect.
