Embodiment one
Stator ring is a large amount of parts used in gas turbine, due to the hot environment of gas turbine, and the irregular distance change caused because of the temperature difference of stator interannular, what make stator interannular is sealed to a great problem.
The embodiment of the present invention one provides a kind of stator ring sealing configuration of gas turbine, and shown in composition graphs 3 and Fig. 4, sealing structure comprises the first stator ring 1, second stator ring 2 and Sealing 3; The side that second stator ring 2 is relative with the first stator ring 1 is provided with annular slot; The quantity of Sealing 3 is multiple, its inside and outside both sides are respectively the arcuate structure of fitting with the second stator ring and the first stator hoop, in order to bear high temperature, Sealing 3 is preferably made up of refractory stainless steel 0Cr18Ni9 material, and multiple Sealing 3 all slides and is inserted in annular slot.
The two ends of each Sealing 3 all offer inserting groove, inserting groove at least will run through the air inlet side of Sealing 3, plugging plate 7 is provided with cutting graftage part, plugging plate 7 is actively plugged in the inserting groove of adjacent two Sealings 3 by cutting graftage part, can slide with the distance change between two Sealings 3 and keep plugging state in cutting graftage part in inserting groove, the cutting graftage part of plugging plate 7 is inserted along the air inlet side of Sealing, fit with the outside of the second stationary ring and the inner side of the first stationary ring respectively in the bottom of plugging plate and top, be close to the air inlet side of Sealing under the action of the forces of the wind, form good sealing.
The flexible mechanism 5 of the equal elastic support in bottom of each Sealing 3, elastic mechanism 5 seals for making to be formed to contact between Sealing 3 with the first stator ring 1.When there is the change of relative gap due to the change of the temperature difference between the first stator ring 1 and the second stator ring 2, the elastic mechanism 5 below each Sealing 3 makes the top moment of each Sealing 3 keep sealing with the first outside stationary ring 1.
Along with the first stationary ring 1 expansion or reduce, the gap between each Sealing 3 can change, and the cutting graftage part of each Sealing 7 has grafting surplus in each inserting groove, the moment can keep inserting state; The sealing plate of Sealing 7 width there is surplus, the change in gap between Sealing 3 can be adapted to.In addition, along with the spacing between the first stator ring 1 and the second stator ring 2 diminishes gradually, the elastic force of elastic mechanism 5 increases gradually, has stronger bearing capacity, and can keep good sealing effect.
As shown in Figure 3, elastic mechanism 5 spring that comprises limiting stopper 4, be arranged on the spring chamber below annular slot and be arranged in spring chamber; Spring chamber runs through the bottom surface of the second stator ring 2, and elasticity 5 is arranged in spring chamber; Be communicated with by pin shaft hole between spring chamber with annular slot, elastic mechanism 5 passes through limiting stopper 4 elastic support in the bottom of Sealing 3; One end of limiting stopper 4 is provided with bearing pin, and bearing pin passes described pin shaft hole and is against the bottom of described Sealing 3.Spring retainer portion is plugged in one end of spring, and the other end of spring is connected with the second stator ring.
Should be noted that, spring retainer portion also can be sleeve-shaped and be socketed in outside spring, as long as make the external diameter of limiting stopper 4 and the internal diameter of spring chamber adapt, formed in radial direction to limiting stopper 4 spacing, reduce elastic support effect to avoid spring run-off the straight; The other end of limiting stopper 4 is provided with bearing pin, and bearing pin passes pin shaft hole and is against the bottom of Sealing 3, and bearing pin shuttles back and forth up and down along pin shaft hole, thus makes both ends of the spring reduce elastic performance without relative dislocation.The opening activity of spring chamber is inserted with embolism 6, and embolism 6 is preferably connected with spring chamber screw-thread fit, and the bottom of spring can also be fixedly connected with limiting stopper 4, makes limiting stopper 4 and the convenient installation of spring.
Preferably, the quantity of Sealing 3 is at least three, integral extension or the reduction volume of the annular formed by multiple Sealing 3 are like this shared on each gap, avoid the spacing variable quantity between adjacent two Sealings 3 excessive, if the spacing variable quantity of Sealing 3 is excessive, need that inserting groove is offered darker, and due to the finite thickness of Sealing 3, crossing dark inserting groove easily causes the integral sealing effect of Sealing 3 to decline, or the thickness of Sealing 3 cannot meet the depth requirements of inserting groove at all.
In addition, two elastic mechanisms 5 are arranged at the bottom of each Sealing 3 at least elastic support, to make the stress equalization everywhere of Sealing 3, ensure that the top of each Sealing 3 is formed to seal with the first stator ring equably and crimp.
The side of annular slot is provided with the first boss 21, the side of Sealing 3 is provided with the second boss 31, second stator ring 2 is split-type structural, can be spliced by semicircular second stationary ring of two 180 °, be formed spacing for the below making the second boss 31 be set to the first boss 21 by the linking section card of the second stationary ring 2.And the second boss 32 of Sealing 3 is arranged on the air inlet side of Sealing 3, the back side of Sealing 3 and the opposite side sidewall of annular slot are plane contact, and Sealing 3 under the action of the forces of the wind its back side seals with the side walls of annular slot and contacts.
The installation process of the present embodiment one and using state are:
The section part of the second stator ring is had by each Sealing to snap onto in annular slot successively, plugging plate is inserted between each Sealing, limiting stopper is encased in spring chamber, its bearing pin is made to be against the bottom of Sealing through pin shaft hole, now a hand can by limiting stopper by spring eye, another is hand-held holds embolism, make in the spring retainer portion of the spring housing at embolism top bottom limiting stopper, tighten embolism again, plug surface can be coated with anti-bite mixture, under preventing high temperature condition, screw thread generation occlusion cannot be dismantled; Limiting stopper is by Sealing jack-up under spring force effect, and mineralization pressure between the top of Sealing and the first stator ring is sealed, and between the second boss of Sealing and the first boss of annular slot, mineralization pressure seals, and completes installation thus.
During use, because the sealing plate of plugging plate blows direction towards gas, plugging plate can be fitted with Sealing under the action of the forces of the wind, forms sealing to the gap between Sealing; Moving after entirety under Action of Wind pressure of multiple Sealing, the back side of each Sealing and the sidewall of annular slot form relative pressure and seal.
When the diameter of the first stator ring increases, the gap between each Sealing also can increase thereupon, and slides in the cutting graftage part of each plugging plate in the inserting groove between two between Sealing, because cutting graftage part has grafting surplus, can not skid off from inserting groove; The sealing plate of plugging plate also has surplus relative to the gap between two between Sealing, also can keep blocking and sealing.
When the spacing of the first stator ring and the second stator ring increases, each Sealing can under the effect of elastic mechanism the moment keep the sealing with the first stationary ring, the sealing state between each Sealing is the same.In addition because the spacing of the first stator ring and the second stator ring changes, the phenomenon in the gap cannot blocked between whole piece Sealing may be there is in the sealing surface of plugging plate, but the spacing due to the first stator ring and the second stator ring changes can not very greatly, its variable quantity is only 1 ~ 2mm in the ordinary course of things, and the gap place of non-shield portions again between Sealing, its air leakage is very small, can not have an impact to the sealing between stator.
Embodiment two
The stator ring sealing configuration of a kind of gas turbine that the present embodiment two provides, its structural type is substantially identical with embodiment one, and something in common repeats no more, and difference is:
As shown in Figure 5, the first boss 21 is positioned at the opening of annular slot, and its lower surface slopes inwardly in the radial direction of annular slot, the radially-inwardly inclination of the upper surface of the second boss 31 annularly draw-in groove, make the radial direction of the surface of contact of the first boss 21 and the second boss 31 annularly draw-in groove oblique tilted, when the support force of elastic mechanism 5 pairs of Sealings 3 equals longitudinal pressure sum to the second boss 31 of the pressure of the first stator ring 1 pair of Sealing 3 and the first boss 21 (gravity of Sealing 3 is ignored), namely when the pressure of the first stator ring 1 pair of Sealing 3 is less, between the top of Sealing 3 and the first stator ring 1, and keep crimped status between the second boss 31 of Sealing 3 and the first boss 21 of the first stator ring 1 and seal, formed between first stator ring 1 and the second stator ring 2 and seal.There is the prerequisite of relative pressure between the first boss 21 and the second boss 31 under, when distance when between the first stator ring 1 and the second stator ring 2 changes, relative sliding is there is between second boss 31 meeting and the first boss 21, and Sealing 3 also produces displacement in the vertical, therefore make between the top of Sealing 3 and the first stator ring 1 and the second stator ring 2, by the contact between the first stator ring 1 and Sealing 3 and the contact between the first boss 21 and the second boss 31, dynamic touch seals.
Side sidewall relative with the first boss 21 in annular slot is provided with the bottom land of the 3rd boss the 22, three boss 22 close to annular slot, the oblique outer incline of radial direction of the upper surface of the 3rd boss 22 annularly draw-in groove; Side relative with the second boss 31 on Sealing 3 is provided with the radial direction oblique outer incline of lower surface along Sealing 3 of the 4th boss the 32, four boss 32, thus the oblique outer incline of radial direction of the surface of contact of the 3rd boss 22 and the 4th boss 32 annularly draw-in groove.When the pressure of the first stator ring 1 pair of Sealing 3 equals the support force sum of the 3rd boss 22 to the longitudinal pressure of the 4th boss 32 and elastic mechanism 5 pairs of Sealings 3 (disregarding the self gravitation of Sealing 3), namely when the pressure of the first stator ring 1 pair of Sealing 3 is larger, between the top of Sealing 3 and the first stator ring 1, and the 3rd is formed between boss 22 and the 4th boss 32 and seals, and namely keeps sealing between the first stator ring 1 and the second stator ring 2.There is the prerequisite of relative pressure between the 3rd boss 22 and the 4th boss 32 under, when distance when between the first stator ring 1 and the second stator ring 2 changes, relative sliding is there is between 3rd boss 22 and the 4th boss 32, Sealing 3 also produces displacement in the vertical, makes thus to remain sealing by the contact between the first stator ring 1 and Sealing 3 and the contact between the 3rd boss 22 and the 4th boss 32 between the first stator ring 1 and the second stator ring 2.
The using state of embodiment two is:
When first stator ring distance the second stator ring is far away, spring produces support force upwards by limiting stopper to Sealing, first stationary ring and the first boss produce downward pressure to Sealing, now between the first stator ring and Sealing, and are formed between the first boss and the second boss and seal;
When the first stator ring is gradually near the second stator ring, there is downward displacement in Sealing thereupon, relative sliding is there is between second boss and the first boss, and relative pressure therebetween reduces gradually, until be reduced to zero, now produce relative pressure gradually between the 3rd boss and the 4th boss and form sealing.
Along with pressing down of Sealing, limiting stopper is along spring groove slide downward, spring is subject to the spacing of limited part and longitudinal compression, the elastic force of spring increases along with increasing progressively of decrement, therefore bearing capacity also strengthens thereupon, and when the spacing between the first stator ring and the second stator ring changes, between Sealing and the second stator ring, remain sealing state.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
