On valve body 1；Hood 3 is threadedly connected on valve gap 2, for a large amount of exhausts and the structure of air-breathing；Guide pin bushing 4 is used for as piston 8
Vertical movement is oriented to and is fixed on valve gap 2；Sealing ring 5 is fixed between valve gap 2 and piston shelf 7 is used for primary seal；It is spacing
Plate 6 is used to control the sealed vol of piston 8, should reach seal request, and the service life of excessive impact rubber seal ring 5；
It is screwed on piston shelf 7 in valve gap 2, limiting piston is lower to be used to be oriented to main ball lever 9；Piston 8 be limited in limiting plate 6 with
Between piston shelf 7 and follow the vertical movement up and down of main ball float 9；Main ball float 9 is sagging on hydro powered lower band piston 8 is made
Straight motion；Bumper bracket 102 is screwed is used for the lower limit for limiting buffering ball float 101 on sliding axle 103；Buffering ball float
101 slide up and down to be placed on sliding axle 103 with fluid, reach keying, throttling, the effect of buffering；Sliding axle 103 uses plug screw
105 are fixed between valve body 1 and lower carriage 104, are cased with buffering ball float 101 and bumper bracket 102 on sliding axle 103；Lower carriage 104

The upper-lower position of moving axis 103；Ball valve 11 is fixed on valve body 1 by joint, for excluding the sewage in valve body 1；Sewage combined type
Air bleeding valve be suitable to be installed at pump outlet or delivery water pipeline in, to exclude pipeline in a large amount of air assembled, while
The micro-air that pipeline higher position is assembled is emitted in air, to improve pipeline and water pump service efficiency, and in pipe once
When having negative pressure to produce, this valve can immediately wick into outside air, it is to avoid pipeline causes the generation of tube breaking phenomenon because of negative pressure.Work as water delivery
When starting water filling in pipe, piston 8 or buffering ball float 10.1 rest on open position, are vented in a large number.When air is drained, valve
Internal water accumulation, ball float is floated, and piston 8 or buffering ball float 101 stop a large amount of exhausts to closed position.When water is normally conveyed in pipe
When, certain degree is arrived in valve if any a small amount of air accumulation, water level decreasing in valve, two ball floats decline therewith, now a small amount of air
Discharged by hollow stem steam vent.When water pump stops, when producing negative pressure in in-pipe flow space-time or chance pipe, the unlatching rapidly of piston 8 is inhaled
Enter air, it is ensured that pipeline safety, sewage sprays when reducing a large amount of exhausts, makes dirt be unlikely to be deposited on piston seal face,
And internals are hardly damaged more resistant to water slug, make degassing function normal operation.When air bleeding valve has negative pressure to produce in pipe, piston should
This can be opened rapidly, and outside air is sucked in a large number, to ensure that pipeline will not produce infringement because of negative pressure.For high flow rate, frequency
Numerous operating mode for starting water pump, to slow down water impact, buffering plug valve should prevent a large amount of water sprays but not affect a large amount of exhausts, make
Emptying effectiveness is unaffected, and effectively prevents water hammer from occurring.
As shown in Fig. 2 the working condition of a large amount of exhaust sections is：
Operation principle is：
Water-carriage system starts water filling exhaust, is failure to actuate without hydro powered because buffering ball float and piston, so low voltage difference is unobstructed
A large amount of exhausts.
As shown in figure 3, the working condition of throttling exhaust section is：
| Element | Position | Action | State |
| Piston： | Nearly sealing station | Sliding upwards | Throttling exhaust |
| Buffering ball float | Nearly throttle position | Sliding upwards | Throttling exhaust outlet water hammer-resistant |
Operation principle is：
Air is gradually drained, gradually water filling in valve, and piston slides onto closed position on the main ball float of hydro powered, and buffering is floating
Ball slides onto throttle position in hydro powered, basic to stop a large amount of exhausts.After the final throttling by water, ball float Slow Close water hammer-resistant.
As shown in figure 4, the working condition of micro exhaust section is：
| Element | Position | Action | State |
| Piston： | Sealing station | The main ball float ascending piston of hydro powered is closed | The micro exhaust of hollow stem |
| Buffering ball float | Throttle position | Hydro powered buffering ball float rises closes | Medium does not flow |
Operation principle is：
After current are buffered, buffering ball float is driven by moving on to throttling position, piston in hydro powered by the current of main ball float
Dynamic to float closing, dissolved gas aggregation, when water is normally conveyed in pipe, if any a small amount of air accumulation certain degree is arrived in valve,
Piston will not be shifted because of medium differential pressure, period, but water level can decline in valve, and main ball float declines therewith, and now a small amount of air passes through
Hollow stem aperture is automatically drained out minimum gas.
As shown in figure 5, the working condition of a large amount of inspiratory limbs is：
| Element | Position | Action | State |
| Piston： | Reset | Original position is slid onto vertically downward | A large amount of air-breathings |
| Buffering ball float | Reset | Original position is slid onto vertically downward | A large amount of air-breathings |
Operation principle is：
When termination of pumping is cut off the water, in-pipe flow space-time or pipe in produce negative pressure when, piston and buffering ball float open rapidly, vertically to
Lower reduction of spondylolisthesis, full flow sucks in a large number air.
