Abstract
The utility model discloses a built-in air buffering air supplement device. A built-in buffering space is composed of a threaded tube, an air supplement spring and an air supplement spring adjusting screw hole plate, wherein the threaded tube is fixed on a valve shaft flange plate. A buffering-moving part is composed of a buffer shaft and a buffer compression piston. Reverse stop valve tubes form a buffer air cylinder air buffer medium part which has the function of quick air intake and controllable air exhaust, wherein the reverse stop valve tubes are installed in guide sealing holes in an air-passing hole plate, an air outlet and 2-4 air inlets are formed at the lower end of each reverse stop valve tube, and an upper spring is installed at the upper end of each reserve stop valve tube. Due to the fact that the built-in buffering technique is adopted, height of the device is greatly reduced, reliability of the device is improved, and therefore the built-in air buffering air supplement device is bound to be widely used in the field of hydroelectric generation.
Description
Technical field:
The utility model relates to a kind of device of tonifying Qi during for hydraulic turbine operation.
Background technique:
At present, be used for the making-up air device of water turbine when breaking away from declared working condition and mainly contain two kinds, a kind of is to make the making-up air device of buffer medium of steam turbine oil, the buffering of this making-up air device is to adopt steam turbine oil damping buffering technology, the pressure that damping produces has just leaked no steam turbine oil in a short period of time, therefore just lost pooling feature, once this making-up air device has lost pooling feature, the powerful impact that making-up air device produces in the course of the work will cause making-up air device to damage; Another kind of making-up air device is to adopt pressurized air as buffer medium, but thisly utilize making-up air device complex structure, the volume that pressurized air reaches cushioning effect greatly, easily to produce jam, as just being easy to produce jam at four reverse stop valves on damper piston in closing process, cause making-up air device to be not closed completely, cause the serious consequence of leaking.The hydraulic generator unit is badly in need of that a kind of volume is little, simple in structure, the making-up air device of fault-free, good buffer effect.
Summary of the invention:
The utility model aims to provide a kind of new technological scheme that can satisfy present hydraulic generator unit tonifying Qi needs, has the advantages such as volume is little, simple in structure, cushioning effect is good.it has casing, the tonifying Qi spring, valve shaft, valve port seat flange, valve gap be connected gusset, it is characterized in that, central position above the solid valve shaft flange plate on valve shaft of buffer shaft, the buffer compression piston is fixed on the buffer shaft upper end, threaded pipe is fixed on above the valve shaft flange plate with threaded pipe centered by buffer shaft close bolt, axle sleeve and axle sleeve lid are passed in the valve shaft lower end, with the valve shaft nut, valve shaft and valve gap are fixed together again, casing is used by 4 connection gussets be fixed on valve port seat flange center position, the tonifying Qi spring is inserted in threaded pipe to the casing bottom, be screwed in above threaded pipe adjusting the screw dish with the tonifying Qi spring of adjusting rotating hole, the lower end is inserted with in the pilot seal hole on the air passing hole plate of bounce cylinder with the reverse stop valve pipe of an exhaust port, 2～4 inlet holes in the lower end, after oppositely stop valve pipe upper end is inserted in upper spring and baffle ring successively, put on again backing pin, have 2～6 air passing holes on air passing hole plate periphery, use bolt upper cover and air passing hole plate are fixed on the casing flange of casing top, make buffer compression piston and bounce cylinder be placed in tonifying Qi spring inner position.
The technique effect that the technological scheme that the utility model provides reaches is such: buffer shaft is fixed on the valve shaft upper end, with threaded pipe after closing bolt and being fixed on threaded pipe on the valve shaft flange plate, again the buffer compression piston is fixed on the buffer shaft upper end, then makes valve shaft pass axle sleeve and the axle sleeve lid is fixed together with valve shaft nut and valve gap.Connect gussets with 4 casing is fixed on valve port seat flange center, with the valve body bolt, valve port seat flange is fixed on above the blowdown pipe flange of blowdown pipe.The tonifying Qi spring is inserted in threaded pipe is placed in casing, the tonifying Qi spring of screwing in the threaded pipe upper end is adjusted the screw dish, makes valve gap contact sealing with valve port seat flange by certain pressure.Put into the pilot seal hole with the reverse stop valve pipe of an exhaust port, 2～4 inlet holes, upper spring and baffle rings, bounce cylinder is enclosed within above the buffer compression piston again, make it after the tonifying Qi spring inner, use bolt upper cover and air passing hole plate and casing are fixed together.
When blowdown pipe moment formation vacuum, valve gap is under atmospheric effect, the spring that overcomes the tonifying Qi spring moves down to be opened, make air fill into rapidly the region of no pressure, this moment, the buffer compression piston also moved down rapidly together with valve shaft and buffer shaft, in bounce cylinder upper end formation vacuum, reverse stop valve pipe was moved down, air enters in bounce cylinder simultaneously, when degree of vacuum in bounce cylinder disappears, oppositely the stop valve pipe under the elastic force effect of upper spring, on move and close.after blowdown pipe is filled into air, degree of vacuum disappears, valve gap is under the effect of tonifying Qi spring, by threaded pipe and valve shaft, valve gap is moved on rapidly, air in simultaneous buffering compression piston compression bounce cylinder, to reach the absorption to valve gap kinetic energy, thereby move the buffering of speed on having reduced, in the process of pressurized air buffering, air is also constantly discharged from exhaust port, but discharge air quantity and can not affect cushioning effect, therefore, exhaust port must reasonably calculate and process, so, the air that exhaust port is discharged is controlled, can make device that present technique relates to be in all the time the optimum state of buffering.After pressurized air was completed cushioning effect, all participated in the air of buffering and all can discharge within the time that requires from exhaust port, and valve gap and valve port seat flange are closed closely.
Technological scheme provided by the utility model has adopted built-in buffering method, so its structure is optimized more and compactness, install simple and convenient, owing to having dwindled significantly volume, improved reliability, make operating life longer, solved veritably the little installation question that brings in hydraulic generator unit vacuum gas supplementary space, be one and have novelty, creativeness, practicability, and the technological scheme that can produce fully, will be widely used in the fields such as hydroelectric power.
