Embodiment
The structural representation of the embodiment one that Fig. 1 provides for the utility model, as shown in Figure 1, the discharging valve of the present embodiment comprises: valve nozzle 3, valve gap 4 and valve gap connecting rod 6.
Wherein, valve nozzle 3 is provided with valve gap seat 8, valve gap seat 8 can be welded on valve nozzle 3, valve gap 4 is arranged on the side of valve nozzle 3, valve gap 4 is provided with valve gap contiguous block 5, valve gap connecting rod 6 and valve gap seat 8, valve gap contiguous block 5 Spielpassung, the scope of gap value is 0.5 millimeter to 1 millimeter.
Concrete, the discharging valve that the utility model provides is by valve gap connecting rod 6 and valve gap seat 8, valve gap contiguous block 5 Spielpassung, when being malleation in negative pressure tailrace inner chamber, under the momentum effect of water, back down valve gap 4 and water is discharged, after draining terminates, valve gap 4 can be fitted with valve nozzle 3 under gravity, thus realize valve gap 4 automatic opening-closing, without the need to artificially participating in opening and closing valve gap 4, save manpower.
Further, on the basis of above-described embodiment, the structural representation of the embodiment two that Fig. 2 provides for the utility model, as shown in Figure 2, the side that valve nozzle 3 and valve gap 4 are fitted is provided with groove (not shown), be provided with seal washer 9 in groove, seal washer 9 is specifically as follows elastic packing packing ring, such as rubber gasket.
In the present embodiment, valve nozzle 3 and valve gap 4 all can be set to circle, and certain valve nozzle 3 and valve gap 4 can also adopt other shapes, are not construed as limiting in the present embodiment.When discharging valve 3 is arranged on negative pressure tailrace, under the state that negative pressure tailrace does not work, the center of circle of valve nozzle 3 and valve gap 4 overlaps, in the process of negative pressure tailrace work, under the effect of negative pressure, due to valve gap connecting rod 6 and valve gap seat 8, valve gap contiguous block 5 Spielpassung, the center of circle of valve gap 4 has the movement of certain limit relative to the center of circle of valve nozzle 3, cause and cover imprecision and to leak gas leakage, in order to negative pressure tailrace bore seal can be kept within the scope of this, , valve nozzle 3 is fitted with valve gap 4 side groove in seal washer 9 is set, like this, even if in use, the center of circle of valve gap 4 moves up and down 2 millimeters relative to the center of circle of valve nozzle 3, under suction function, seal washer 9 still can compress by valve gap 4 automatically, thus ensure negative pressure tailrace bore seal.
Further, on the basis of above-described embodiment, valve gap connecting rod 6 is by the first screw 2 and valve gap seat 8 Spielpassung, and valve gap connecting rod 6 is by the second screw 1 and valve gap contiguous block 5 Spielpassung.
Spielpassung between valve gap connecting rod 6 and valve gap seat 8, valve gap contiguous block 5, can make valve gap connecting rod 6 flexible rotating, thus valve gap 4 is freely covered on valve nozzle 3 under external force, realize valve gap 4 automatic opening-closing, saves manpower.
Further, on the basis of above-described embodiment, between valve gap 4 and valve gap contiguous block 5, be provided with adhesive-layer (not shown), by adhesive-layer, valve gap 4 and valve gap contiguous block 5 fixed.
