Embodiment
As shown in Figure 1 and Figure 2, gravity drive hydrodynamic system depression drainage device of the present invention includes fluid reservoir 1, installed in fluid reservoir 1
On drainage tube 2 and negative tube 3, fluid reservoir 1 be used for deposit draining fluids, use for convenience, can also be in the bottom of fluid reservoir 1
It is provided with the delivery pipe 11 of valve.The negative tube 3 connects negative pressure generator, and the negative pressure generator includes what is be coaxially disposed
Price fixing 4 and Moving plate 5, the price fixing 4 and Moving plate 5 are vertically disposed disc, and price fixing 4 is fixedly installed, and Moving plate 5 is rotatably
It is arranged on the front of price fixing 4.Negative pressure access aperture 41 is provided with the upper end of price fixing 4, the negative tube 3 is connected to negative pressure access aperture
On 41, steam vent 42 is provided with the lower end of price fixing 4, the distance of the steam vent 42 away from axle center is less than negative pressure access aperture 41 away from axle
The distance of the heart；Be provided with Moving plate 5 negative pressure hole 51, lower negative pressure hole 52 and air holes 53, on stomata 54, the upper negative pressure
The position correspondence negative pressure access aperture 41 in hole 51, the position of the lower negative pressure hole 52 is symmetrical with the upper axle center of negative pressure hole 51, the lower gas
The position correspondence steam vent 42 in hole 53, the position and the axle center of air holes 53 of the upper stomata 54 is symmetrical.The upper negative pressure hole 51, under
Negative pressure hole 52 and air holes 53, the back side of upper stomata 54 are provided with the closure gasket groove that diameter is more than aperture, the sealing ring
