And, described inverted U spring opposite side O-ring seal body is shaped with extruding inclined-plane.
And described sealing contact jaw is arranged on the middle part of corresponding inverted U spring side.
And described O-ring seal body is processed by teflon and carbon fiber.
And the material of described inverted U spring is AISI301 stainless steel.
Advantage of the present invention and beneficial effect are:
This is used for the slipper seal structure of the High Temperature High Pressure of steam ejection device, it comprises steam ejection steel cage, steam ejection steel cylinder, first O-ring seal, second O-ring seal, first wearing ring and the second wearing ring, steam ejection steel cage is sleeved in steam ejection steel cylinder, first O-ring seal and the second O-ring seal are sleeved in the groove of the steam ejection steel cage outer wall between steam ejection steel cage and steam ejection steel cylinder, steam ejection steel cage outer wall outside the first O-ring seal is fixedly mounted with the first wearing ring, steam ejection steel cage outer wall outside the second O-ring seal is fixedly mounted with the second wearing ring, this first O-ring seal and the second O-ring seal include O-ring seal body, setting-in one inverted U spring in O-ring seal body, the O-ring seal body of inverted U spring side integrally makes sealing contact jaw, be shaped with domatic opposite side in sealing contact jaw side and be shaped with Caused by Sloping Surfaces, sealing contact jaw and steam ejection steel cylinder close contact, simplicity of design of the present invention, scientific and reasonable, good sealing effect, long service life, the long-term stability of effective guarantee integral device is run.

Fig. 2 is the structural representation of the present invention first O-ring seal.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of slipper seal structure of the High Temperature High Pressure for steam ejection device, it comprises steam ejection steel cage 1, steam ejection steel cylinder 5, first O-ring seal 3, second O-ring seal 4, first wearing ring 2 and the second wearing ring 6, steam ejection steel cage is sleeved in steam ejection steel cylinder, first O-ring seal and the second O-ring seal are sleeved in the groove of the steam ejection steel cage outer wall between steam ejection steel cage and steam ejection steel cylinder, steam ejection steel cage outer wall outside the first O-ring seal is fixedly mounted with the first wearing ring, steam ejection steel cage outer wall outside the second O-ring seal is fixedly mounted with the second wearing ring, this first O-ring seal and the second O-ring seal include O-ring seal body 7, setting-in one inverted U spring 8 in O-ring seal body, the O-ring seal body of inverted U spring side is integrally made sealing contact jaw 10, be shaped with domatic 9 opposite sides in sealing contact jaw side and be shaped with Caused by Sloping Surfaces 11, sealing contact jaw and steam ejection steel cylinder close contact, described inverted U spring opposite side O-ring seal body is shaped with extruding inclined-plane 12, sealing contact jaw is arranged on the middle part of corresponding inverted U spring side.O-ring seal body is processed by teflon and carbon fiber, and can reach the heat resistance demand of system, compressed shape diminishes.The compactness of teflon own is high, can solve High Temperature High Pressure bubble and to expand the destruction of causing, and have good frictional behavior and wear resistance, all have good sealing effect in Static and dynamic process.Sealing the margin adopts less end contact, and play and reduce friction, the effect increased the service life, the material of inverted U spring is AISI301 stainless steel, and it has excellent ductility, wear resistance and fatigue resistance.
The load required for low pressure lower seal is provided by inverted U spring when the present invention works, strengthened by inverted U spring opening after working pressure and temperature raise and further improve sealing load, make sealing contact jaw and steam ejection cylinder barrel close contact, effectively realize sealing.Simultaneously, when system works is pressurizeed, second is used for the upper domatic and Caused by Sloping Surfaces of slipper seal structure of the High Temperature High Pressure of steam ejection device and first are subject to high pressure steam Vertical direction squeezing action for the Caused by Sloping Surfaces of the slipper seal structure of the High Temperature High Pressure of steam ejection device, make the extension that sealing material occurs to a certain degree in the horizontal direction, seal face contacts more tight with cylinder barrel, further enhanced leaktightness effect.Upper and lower two circle wearing rings, can imbalance in balance exercise process stressed, not only play good leading role, and the effective working life extending sealing material, black box adopts double sealing, effectively raises sealing effect, extends the working life of sealing system.
