Abstract
The invention discloses a maintenance sealing device for water turbines. The maintenance sealing device is characterized in that a dovetail maintenance sealing form is adopted, rubber is directly pressed to form a maintenance seal, the maintenance seal is free of middle holes, a sealing strip is pressed into a specific groove in a sealing socket, a sealing gland is arranged on the upper surface of the sealing socket and is fixed onto the sealing socket by a bolt, a sealing groove for preventing air leakage is further arranged on the sealing socket, a rubber strip is arranged inside the sealing groove to prevent air from leaking, and accordingly the sealing gland, the maintenance seal and the sealing socket are integrated. An inflating stepped hole is arranged on the sealing socket, and compressed air is directly pressed on the maintenance seal, so that the maintenance seal is fully arranged in a gap between a spindle and the sealing socket, and the purpose of sealing water is achieved.
Description
Technical field
The present invention relates to hydraulic turbine generator design of Sealing Structure field, relate in particular to a kind of water turbine maintenance seal arrangement.
Background technique
At present, the general structure of water turbine maintenance sealing is air shroud formula structure, utilizes the shroud of mould compacting to be contained in standing part, is filled with pressurized air when shutting down maintenance, makes the shroud expansion, and the gap between sealing and main shaft is to reach the effect of water shutoff.The making of this kind structure shroud is complicated, not only want hollow in the rubber of making shroud, also to be pressed into spring and spring seat in shroud, complex process, also need reserve the joint that is filled with compressed-air actuated special use on shroud, joint is rigid construction, and needs to adopt the form that directly is pressed between flexible pipe, make difficulty, complex process.
Summary of the invention
The invention provides a kind of simple in structure, practical, the water turbine of good sealing effect maintenance seal arrangement.
Technological scheme of the present invention is: the invention provides a kind of water turbine maintenance seal arrangement, it is characterized in that: the maintenance seal form that adopts swallow-tail form, this kind maintenance sealing directly forms with the rubber compacting, middle without the cavity, in specific groove in Stamping Steel Ribbon indentation sealing seat, the above is provided with sealing gland, with bolt, sealing gland is fixed on sealing seat, also have on sealing seat and prevent the seal groove that leaks gas, rubber strip is housed in groove, prevent that gas from exposing, like this, make sealing gland, maintenance sealing and sealing seat become one.Have the inflation step hole on sealing seat, pressurized air is directly overwhelmed in the maintenance sealing, make maintenance seal the gap that is full of between main shaft and sealing seat, to reach the effect of water shutoff.
described a kind of water turbine maintenance seal arrangement, it is characterized in that: described a kind of water turbine maintenance seal arrangement, its structure is: maintenance seals top and is provided with sealing gland, sealing gland be provided with overhaul the sealing match shape groove, also be provided with on sealing seat with overhaul the sealing match shape groove, the sealing seat upper surface is provided with the step that matches shape with the sealing gland lower surface, sealing gland is provided with tapped through hole, sealing seat is provided with the tapped hole of and the logical heart identical with tapped through hole diameter on sealed cover, to push down maintenance and seal with maintenance sealing match position that the groove of shape aims at the maintenance sealing on sealing gland, and will overhaul sealing and be pressed on sealing seat the groove that matches shape with the maintenance sealing, bolt is screwed into and passes the tapped through hole on sealing gland, be screwed into the tapped hole on sealing seat and tighten, make sealing gland, maintenance sealing and sealing seat become one, sealing seat is provided with and prevents the seal groove that leaks gas, rubber strip is housed in groove, sealing seat is provided with the inflation step.
Beneficial effect of the present invention is: simple in structure, practical, and good sealing effect.
