Hole, the position of the lower negative pressure hole is symmetrical with upper negative pressure hole axle center, the position correspondence steam vent of the air holes, the upper stomata
Position and air holes axle center it is symmetrical, upper negative pressure hole and lower negative pressure hole are the circular hole parallel to Moving plate axis, air holes and upper
Stomata is the inclined hole with Moving plate Axis Cross；Upper shell and lower house, the upper shell covering are provided with the front of Moving plate
On upper negative pressure hole and upper stomata, the lower house is covered in air holes and lower negative pressure hole, upper shell and the paraxial heart of lower house
One end connected by connecting tube.
The price fixing is fixedly mounted on support, and rotating shaft is provided with the axle center of the price fixing, and the Moving plate passes through bearing
In rotating shaft.
The beneficial effects of the present invention are：The disc type depression drainage device is driven using liquid gravity, and without electric energy, negative pressure is held
Continuous time length, pressure stability, reliability are high.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the positive structure schematic of Moving plate.
Fig. 3 is Fig. 1 A portions close-up schematic view.
Embodiment
As shown in Figure 1 and Figure 2, disc type depression drainage device of the present invention includes fluid reservoir 1, drawing on fluid reservoir 1
Flow tube 2 and negative tube 3, fluid reservoir 1 are used to deposit draining fluids, use for convenience, can also set band in the bottom of fluid reservoir 1
Valvular delivery pipe 11.The negative tube 3 connects negative pressure generator, and the negative pressure generator includes the price fixing 4 being coaxially disposed
With 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 arranged
In 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 41
On, 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 center
Distance；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 hole
51 position correspondence negative pressure access aperture 41, the position of the lower negative pressure hole 52 is symmetrical with the upper axle center of negative pressure hole 51, the air holes
53 position correspondence steam vent 42, the position and the axle center of air holes 53 of the upper stomata 54 is symmetrical.Upper negative pressure hole 51 and lower negative pressure
Hole 52 is the circular hole parallel to the axis of Moving plate 5, and air holes 53 and upper stomata 54 are the inclined hole with the Axis Cross of Moving plate 5, such as
Shown in Fig. 3, axle center of the shallow end away from Moving plate 5 of the inclined hole, and the depths of inclined hole moves closer to the axle center of Moving plate 5.When inclined hole position
When above the axle center of Moving plate 5, the positive inclined hole opening of Moving plate 5 is in the state raised up, when inclined hole is located at below the axle center of Moving plate 5
When, the positive inclined hole opening of Moving plate 5 is in the state tilted down, can so avoid the liquid fallen from pouring into inclined hole.
