In mixing chamber.Between the Drainage Section outer wall of nozzle and the cooperation section inner wall of tailstock formed inflatable chamber 15, the end face of Drainage Section with
Gas passing gap 11 is formed between tailstock.Through air inlet-inflatable chamber-gas passing gap, it is equivalent to the runner for foring gas, this stream
The structure in road is that nozzle is cooperatively formed with tailstock assembly, and according to different injector specifications, the cross section size of runner can be with
The adjustment of adaptability matches.
In fact, it is exactly gas-liquid mixed chamber that it is practical, which to drain space occupied by cavity, after Drainage Section insertion cooperation intersegmental part
Body inner space, and spot and conveying section that cavity is used as after gas-liquid mixed are drained, the gas-liquid mixed of the external side of drainage lumens
Practical cavity portion is just inflatable chamber, for importing air from the external world.In general, passing through gas piping for air inlet and big conductance
It is logical.It can be connect by connector with tracheae at air inlet.
The flow direction that the gas water body that gas passing gap is drawn passes through, pressure when water body flow will be in inflatable chamber
Air is introduced in Drainage Section through gas passing gap, during air and water mixing, since gas is passed through from wider inflatable chamber
It crosses the second cambered surface changeover portion 19 vertically to cut in water body, moment, pressure with higher reached so that gas-liquid mixed is very abundant
The effect of atomization.
Also, as gas " cutting " enters the difference of path length in water body (entering depth in water body), it is formed by bubble
For size there is also apparent difference, it is bigger to go deep into the pressure that water body center (gas-liquid mixed cavity center) part is lost,
Air Bubble Size caused by tangent from water body is also different.Under normal circumstances, when gas and water body just contact, mutual active force
(impact) is larger, and generated bubble is smaller, minimum even to reach nanoscale bubble.Go deep into gas-liquid mixed chamber center
Domain, gas just keep pressure smaller, and after irrigation pressure effect, it is bigger to be formed by bubble.
After the water body that water pump is pumped into enters feed liquor cavity, arrives at larynx neck (reduction of intracavity diameter moment), generate pressure
Higher water flow enters the gas in inflatable chamber in drainage lumens body through gas passing gap moment " suction ".It should be noted that exactly base
It is sucked in drainage lumens body from the biggish space of inflatable chamber by water body pressure in gas, during by lesser gas passing gap,
Moment generates biggish gas pressure, can generate biggish impingement mix active force with water body.Gas entered from inflatable chamber
Guiding between gas gap by the second cambered surface transition structure, resistance is small, and gas flowing is smooth, will not cause to damage to gas pressure
It loses, ensure that gas reaches biggish pressure when entering gas passing gap.
Above-mentioned injector working principle is the improvement carried out based on Venturi effect to structural member, so-called venturi effect
The principle answered is when blowing air over obstacle, and near ports air pressure is relatively low above the leeward of obstacle, to generate
Suction-operated and the flowing for leading to air.The principle of Venturi tube is in fact very simple, it be exactly air-flow from the coarse to fine, to accelerate gas
Body flow velocity, makes gas form " vacuum " area in the rear side of venturi outlet, this vacuum area can generate certain absorption and make
With.Injector introduces fresh air by nozzle and tailstock combination settings, by the air inlet of tailstock, and is formed between tailstock and nozzle
Inflatable chamber in of short duration storage, nozzle chamber is sucked by extremely narrow gas passing gap, reaches the effect quickly mixed with fluid
Fruit, gas-liquid mixed uniformity is good, generated bubble as low as micron order.
The nozzle and the assembled injector of matched tailstock that the invention is provided, the hydraulic pressure generated by liquid injection
Gas is driven to enter inflatable chamber, and moment generates biggish air pressure and injects water body, can generate a variety of bubbles of different sizes, and
Bubble mixability of different sizes is high, and splendid effect is played to water body purification.
