Background technology
In the industries such as petrochemical industry, Coal Chemical Industry, power system, air separation, substantial amounts of pipeline, pump, valve are widely present
The pressure vessels such as door, reactor.Connection between pipeline, the connection of pressure vessel pressure-bearing boundary, due to the accuracy of manufacture and size
Deviation, there is gap unavoidably.But the material majority that processes of these industry productions is fluid media (medium) and including solid particle
Multiphase flow medium, it is such as gas-solid, liquid-solid, gas-liquid-solid.Under some high-risk operating modes, also exist poisonous, harmful, inflammable, easy
Quick-fried medium, once leaking, will cause seriously environmental pollution and harm personal safety.
The guarantee of sealing property be unable to do without sealing gasket, and at present the main species of conventional sealing gasket have:Graphite pad, graphite gold
Category wound gasket, graphite metal composite strengthening pad, graphite Corrugation pad etc..These pads all have the respective scope of application, but are using
During, often still occur that graphite linings conquassation, metal rebound performance are poor, there are the feelings such as gap between graphite linings and Corrugation pad
Condition.And it is poor to the adaptability of bad working environments, the sealing effectiveness for rising is not good enough, and medium is easily leaked.
The content of the invention
The purpose of the application is the defect for prior art, there is provided one kind inflation metal bellows strengthens soft graphite
Pad, the device can solve the problems, such as that the graphite linings conquassation that sealing gasket is present in background technology, metal rebound performance are poor, significantly improve
Adaptability of the sealing gasket to bad working environments, ensures the sealing of pipeline and pressure vessel.
The technical scheme of the application is:A kind of metal bellows strengthens soft graphite pad, including interior quoit and outer metal
Circle, in the cavity that interior quoit and outer quoit are formed flexible graphite plate is arranged, and flexible graphite plate includes protruding parts, soft
Property graphite cake in be provided with the cavity structure of similar sugarcoated haws, protruding parts is located at the salient position of cavity structure, in cavity knot
The metal bellows of internal cavities is provided with structure, external surface shape and the cavity in flexible graphite plate of metal bellows are tied
The mating shapes of structure, wavy metal is provided with ripple, and position and the protruding parts of ripple match, in the sky of metal bellows
Filled with inert gas in chamber.
A kind of inflation metal bellows as above strengthens soft graphite pad, wherein, in the outer surface of metal bellows
It is provided with coating.
A kind of inflation metal bellows as above strengthens soft graphite pad, wherein, the material of coating is platinum, gold, silver
Or copper.
A kind of inflation metal bellows as above strengthens soft graphite pad, wherein, the road of ripple on metal bellows
Sub-quantity scope is 1~10.
A kind of inflation metal bellows as above strengthens soft graphite pad, wherein, when the passage quantitative range of ripple
For 1~10 when, the quantity of protruding parts adds 1 for the road sub-quantity of ripple.
The remarkable result of the application is:Metal bellows inside filling inert gas, the inert gas can be with system
Temperature rises and expands, and enhances the rebound performance of metal bellows, is particularly suitable for high temperature, high pressure occasion;Soft
Property the bad working environments that disappear of graphite cake ablation under, arranging the metal bellows itself of multi-pass ripple and coating also can realize well
Auxiliary seal effect;The protruding parts that flexible graphite plate is suppressed coordinates preferable with the ripple size of metal bellows, eliminates
Gap between the two so that flexible graphite plate fits even closer with metal bellows;Interior quoit, the outer metal for arranging
Circle effectively prevents flexible graphite plate by conquassation, and has kept out the erosion of medium.

Specific embodiment
The application is described further below in conjunction with the accompanying drawings:
One kind inflation metal bellows strengthens soft graphite pad, including interior quoit 1 and outer quoit 3, in interior quoit 1
Flexible graphite plate 2 is set in the cavity formed with outer quoit 3, and flexible graphite plate 2 includes protruding parts 21, flexible graphite plate
The cavity structure of similar sugarcoated haws is provided with 2, protruding parts 21 is located at the salient position of cavity structure, sets in the cavity structure
Put the metal bellows 4 with internal cavities, the cavity structure in the external surface shape and flexible graphite plate 2 of metal bellows 4
Mating shapes, metal bellows 4 is provided with ripple 41, and position and the protruding parts 21 of ripple 41 match, in metal wave
Filled with inert gas 5 in the cavity of line pipe 4.
Coating 6 is provided with the outer surface of metal bellows 4.
Several specific examples are given below.
As depicted in figs. 1 and 2, inflating metal bellows strengthens soft graphite pad including metal bellows 4 and soft graphite
