Abstract
The utility model relates to a heart-shaped repair sealing structure of a water turbine, which comprises a sealing seat, a sealing cover, a compressed air cavity, an inflation operational component and a heart-shaped solid rubber sealing component. The sealing cover is connected with the sealing seat, the inflation operational component is connected with the compressed air cavity, the heart-shaped solid rubber sealing component is simultaneously embedded in the sealing seat and the sealing cover and comprises two shoulder parts arranged at the top end in parallel and a water sealing part arranged at the bottom end, the compressed air cavity is arranged between the two shoulder parts and props against the heart-shaped solid rubber sealing component, and the water sealing part is inserted in a water leakage port of a clearance of the water turbine to be sealed. The utility model has the advantages that: the heart-shaped repair sealing structure has a long service life, air leakage or breakage cannot be easily caused, and good water sealing effects can be achieved.
Description
[technical field]
The utility model relates to a kind of maintenance sealing structure of water turbine, relates in particular to the heart-shaped maintenance sealing structure of a kind of water turbine.
[background technique]
At present, below the main shaft working seal structure of water turbine, be provided with a maintenance sealing structure usually, its effect is to prevent that when the main shaft working seal structure of compressor emergency shutdown maintenance bearing and bearing bottom tail water from passing through the gap toward machine hole internal leakage.
Please with reference to Fig. 1; Existing maintenance sealing structure be generally hollow Shround-band type maintenance sealing structure 100 '; Comprise a sealing seat 1 ', one with the sealing cover 2 of sealing seat 1 ' be connected ' and compressed air cell 3 ', one with the charge operation part 4 of this compressed air cell 3 ' be connected ' and one be embedded in sealing seat 1 ' and sealing cover 2 ' between hollow rubber Sealing 5 '; Hollow rubber Sealing 5 ' an include cavity 51 ' with a solid rim 52 '; This solid rim 52 ' contain dovetail portion 521 ', said compressed air cell 3 ' place cavity 51 ' in, generally speaking; This compressed air cell 3 ' consistent with cavity 51 ' size, said dovetail portion 521 ' be used to block gap 200 ' scupper.During this hollow Shround-band type maintenance sealing structure 100 ' work; Through operation charge operation part 4 ' be compressed air cell 3 ' inflation; Make cavity 51 ' expand outwardly, indirectly, solid rim 52 ' expansion outward make its dovetail portion 521 ' can with gap 200 ' scupper block more closely; Thereby with gap 200 ' sealing, to reach the purpose of water shutoff.
Hollow rubber Sealing in the above-mentioned hollow Shround-band type maintenance sealing structure need be expanded in the course of the work; Thereby reduced working life; In addition, the hollow rubber Sealing is easily damaged and cause gas leakage in the installing and replacing process, thereby can't reach water sealing effect preferably.
[model utility content]
The utility model technical problem to be solved is to provide a kind of water turbine heart-shaped maintenance sealing structure, not only has long working life, and has water sealing effect preferably.
The utility model solves the problems of the technologies described above through following technological scheme: the heart-shaped maintenance sealing structure of a kind of water turbine; Comprise a sealing seat; One sealing cover that is connected with the sealing seat; One compressed air cell, the charge operation part and that is connected with this compressed air cell is embedded in the heart-shaped solid rubber Sealing in sealing seat and the sealing cover simultaneously, this heart solid rubber Sealing contain two be listed in the top shoulder and be positioned at the water shutoff portion of bottom; Said compressed air cell is located between two shoulders and is pushed against in heart-shaped solid rubber Sealing, and said water shutoff portion inserts in the scupper in water turbine gap of required sealing.
The beneficial effect of the heart-shaped maintenance sealing structure of the utility model water turbine is: adopt heart-shaped solid rubber Sealing and compressed air cell be located on two shoulders of heart-shaped solid rubber Sealing or between; Make heart-shaped solid rubber Sealing need not dilatating and deformable in the course of the work; Thereby has long working life; And, has water sealing effect preferably in the not cracky gas leakage of installing and replacing process.
[description of drawings]
Combine embodiment that the utility model is done further to describe with reference to the accompanying drawings.
Fig. 1 is the sectional view of existing water turbine maintenance sealing structure.
Fig. 2 is the sectional view of the heart-shaped maintenance sealing structure of the utility model water turbine.
[embodiment]
See also Fig. 2; The heart-shaped maintenance sealing structure 100 of the utility model water turbine; Comprise sealing cover 2, one compressed air cells 3 that a sealing seat 1, is connected with sealing seat 1; The one charge operation part 4 and that is connected with this compressed air cell 3 is embedded in the heart-shaped solid rubber Sealing 5 in sealing seat 1 and the sealing cover 2 simultaneously; This heart solid rubber Sealing 5 contain two be listed in the top shoulder 51 and be positioned at the water shutoff portion 52 of bottom, said compressed air cell 3 is located between two shoulders 52 and is pushed against in heart-shaped solid rubber Sealing 5, said water shutoff portion 52 inserts in the scupper in water turbine gap 200 of required sealing.
The utility model is when using: through operation charge operation part 4 is compressed air cell 3 inflations; Make compressed air cell 3 expand outwardly; Compressed air cell 3 advances whole heart-shaped solid rubber Sealing 5 through the power that acts on two shoulders 51 in the process that expands outwardly to gap 200 directions; Thereby make water shutoff portion 52 fully the scupper in gap 200 sealed, and then reach the purpose of water shutoff.
To sum up; Adopt heart-shaped solid rubber Sealing and compressed air cell be located on two shoulders of heart-shaped solid rubber Sealing or between scheme; Make heart-shaped solid rubber Sealing need not dilatating and deformable in the course of the work; Thereby have long working life, and, have water sealing effect preferably in the not cracky gas leakage of installing and replacing process.
Claims (1)
