Abstract
The utility model discloses a buffer type disc form ball float valve. The technical scheme of the utility model is that a floating ball and a buffer spring are arranged between a colonial valve cover and a base, the base and the colonial valve cover are in a fixed connection by 2-4 protective rods, a guide sleeve is fixed in the center of the valve base by 2-4 support arms, one end of the valve shaft is fixed on the colonial valve base, and the other end thereof is penetrated through the guide hole of the guide sleeve, a position-restricted ring is disposed on the other end of the valve shaft and then the position-restricted nut is screwed up, the valve shaft can freely move up and down in the guide hole. The buffer type disc form ball float valve can be widely applied into the field of waterpower generation.
Description
Technical field:
The utility model is a kind of unidirectional Water stop valve that is used for hydraulic turbine generator main shaft blowdown pipe.
Background technique:
Do not allow tail water to enter in the generator on the hydraulic turbine generator in the too high hydroelectric power plant of tailwater elevation, enter in the generator and will cause a serious accident as tail water by the macro-axis blowdown pipe.Adopt monomer float valve and two kinds of technological schemes of Hand-operated butterfly valve at present, monomer float valve processing difficulties, poor sealing performance, and under the effect of water hammer, make its distortion, cause and leak; The Hand-operated butterfly valve workload is big, and operation is also extremely inconvenient, and shutdown need manually be closed, and the machine of opening need manually be opened, and wastes time and energy.For this reason, the too high hydraulic generator unit of tailwater elevation is badly in need of a kind of good seal performance, and anti-water hammer ability is strong, does not need the artificial unidirectional Water stop valve that opens and closes.
The model utility content:
The purpose of this utility model just provides a kind of good seal performance, the technological scheme of the unidirectional Water stop valve that anti-water hammer ability is strong, it is characterized in that, ball float is housed below tapered valve cover and between the base, the central position is fixed with buffer rubber gasket on base, between ball float and the tapered valve cover damping spring is housed, the spring seat ring is put in the damping spring upper end, base is fixed together by 2～4 guard bars and tapered valve cover, guide pin bushing is fixed on the valve seat central position by 2～4 support arms, by set screw nut tapered valve cover is fixed on the valve shaft lower end, after valve shaft passes the guide pin bushing that has pilot hole, load onto limited ring, with stop nut valve shaft and guide pin bushing are linked together, valve shaft can unrestricted motion in guide pin bushing.By joint hole this device is fixed in the blowdown pipe.
The technique effect that technological scheme provided by the utility model realized is such: be installed in the buffering type dish type float valve in the blowdown pipe, open when generator set moves, make air mend region of no pressure into unit by the endless belt of valve seat and tapered valve cover; When shutting down; tail water rises the water hammering that forms rapidly on ball float; ball float rises rapidly under buoyancy, the effect of water attack power; promote to move until closing on the tapered valve cover by damping spring; at this moment; damping spring begins to inhale ball float upper punch energy, and the compression damping spring makes the kinetic energy of ball float upper punch convert the elastic potential energy of damping spring to.After ball float kinetic energy absorbs and finishes, ball float moves down under the effect of damping spring again, after ball float is subjected to the buffer function of buoyancy of water damping and buffering rubber pad in folding process, get back to original position, tapered valve cover has good sealing, so whole device organically combines tapered valve cover, damping spring and the work of ball float process wound property, both had good sealing property, had the ability of anti-water hammer again.
The related technological scheme of the utility model compared with prior art has outstanding progress and significant technique effect, therefore the technical solutions of the utility model novel structure is succinct, produce simple, easy for installation, has novelty, creativeness and practicability, and this programme can produce fully, is bound to be widely used in the hydroelectric power field.
