Background technology
Supercritical water is that a kind of temperature and pressure is in more than critical point, without phase interface, has gas concurrently and liquid is excellent
The fluid of point.Supercritical water fluid technique needs suitable flange to seal for the connection of reactor, fluid line etc..Supercritical
Under conditions of water, temperature is generally greater than 400 degrees Celsius, and pressure is generally greater than 22MPa.The harshness of working condition to Flange joint and
Its sealing means proposes the highest requirement.The flange of general type by bolt by upper and lower Flange joint, its Bolt dismantling
Loaded down with trivial details, not easy-maintaining.The becket pad used seals the highest to sealing surfaces smoothness requirements, holds under high-temperature and high-pressure conditions
Easily reveal, cause major safety risks.In order to meet the working condition of supercritical water High Temperature High Pressure, design safety is reliable, stable
Sealing and Flange joint easy to maintenance and sealing means are the most necessary.
Utility model content
In order to overcome the problems of the prior art, the purpose of this utility model there are provided under a kind of condition of supercritical water
High Temperature High Pressure flange seal structure, this structure is capable of under High Temperature High Pressure safe and reliable, good seal and repair demolition letter
Just flange seal.
For achieving the above object, this utility model adopts the following technical scheme that
High Temperature High Pressure flange under a kind of condition of supercritical water seals structure, including annular flange set, upper flange and under
Flange, upper flange and lower flange are arranged in annular flange set, and are provided with circular ring metal liner on upper flange, upper method
Blue and annular flange set is bolted.
In notch cuttype in described annular flange set.
Described upper flange is with seal groove, and lower flange is with the seal boss matched with seal groove.
The seal groove of described upper flange and the seal boss of lower flange are smooth ring textures.
It is provided with endless metal graphite wound gasket between seal groove and the seal boss of lower flange of described upper flange.
Described annular flange set includes two semi-circular shape flange sleeve, and each semi-circular flange overlaps symmetry in the axial direction and opens
It is provided with tapped through hole.
Described circular ring metal liner includes two semi-circular shape metal liners.
Compared with prior art, the beneficial effects of the utility model are: by using bolt by upper method in this utility model
Orchid is connected with annular flange set, and power is the most directly acted on upper flange by bolt, but power acts on semi-circular shape metal
On liner, it is to avoid the abrasion of upper flange.During dismounting, only need to unclamp slightly bolt, take off semi-circular shape flange sleeve, upper lower flange
I.e. dismantle.Upper lower flange unthreaded hole, bolt is only connected with semi-circular shape flange sleeve, installs and easy removal.
The application scenario of sealing means of the present utility model has popularity, is suitable under supercritical water high-temperature and high-pressure conditions
Use, can also be used with the connection of high-temperature high-pressure reaction kettle, high-temperature, high pressure fluid pipeline etc..
Further, stepped in semi-circular shape flange sleeve, can be effectively matched with upper lower flange.
Further, this utility model have employed the semi-circular shape flange sleeve of activity, easy installation and removal, it is simple to maintenance.
Metallic graphite carbon wound gasket described in the utility model and encapsulating method can realize 750 DEG C, safe and reliable the having under the conditions of 35MPa
Effect seals.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
As it is shown in figure 1, this utility model is a kind of flange sealing structure, it is suitable for making under supercritical water high-temperature and high-pressure conditions
With, including annular flange set 1, a upper flange 2, bolt 3, circular ring metal liner 4, an endless metal graphite wound gasket
5 and a lower flange 6.Seeing Fig. 2, annular flange set 1 includes two semi-circular shape flange sleeve；Upper flange 2 with seal groove,
Lower flange 6 is with seal boss, seal groove and seal boss composition concave-convex type sealing surface.The seal groove of upper flange and lower flange
Seal boss is between smooth ring textures, and the seal groove of upper flange and the seal boss of lower flange and is provided with annular gold
Belong to graphite wound gasket 5.
Described circular ring metal liner 4 includes two semi-circular shape metal liners.
In notch cuttype in described annular flange set 1, can be effectively matched with upper lower flange.
Upper flange 2 is plane with the outer up and down of lower flange 6.Two semi-circular shape metal liners it are placed with on upper flange 2
4.Utilize two semi-circular shape flange sleeve that upper flange 2, lower flange 6 and two semi-circular shape metal liners are stuck in this annular method
In blue set 1.Seeing Fig. 3, Fig. 4 and Fig. 5, each semi-circular flange overlaps symmetry in the axial direction and offers tapped through hole, by bolt 3
Upper flange 2 and annular flange being overlapped 1 seal, by tighting a bolt 3, circular ring metal liner 4 and upper flange 2 contact,
The sealing of lower flange in realization.Power is the most directly acted on upper flange by bolt 3, but power acts on semi-circular shape metal liner
