Technology contents explanation.
Weight is placed in more than the water surface when using or allows weight to swim on the water surface by the present invention, trickle surface contact gas,
Because the flowing of trickle can increase molten gas, because the surface of trickle increases, molten gas can be increased, because trickle is along water conservancy diversion body surface
Surface current moves, and can form continuous vertical liquid level, will not be broken, will not break up the liquid level below gas dissolver, reduce bubble
Produce, reduce the generation of the underwater sound, and because dirty liquid is divided into many trickle fluid columns, and among Practical Project
There can not possibly be duplicate baffle, the vibration frequency of each baffle will not be just the same, and liquid flows down what is evoked
Some cancels out each other air pulsation, reduces the energy that hydraulic shock is converted to air pulsation, plays the effect for reducing the underwater sound
Fruit, when liquid flows down, among inventor's experiment, the underwater sound is can't hear completely, instrument does not detect the underwater sound completely.Present invention reduces gas
Bubble and noise, there is provided a kind of new approaches.Weight makes drainage thread perpendicular to horizontal plane, so that drainage thread will not be because of liquid
Between pressure difference and be attached together, serve prevention trickle merge effect.The effect of weight is to provide to be kept using gravity
The rectilinear form of drainage thread.The drainage thread of the present invention can facilitate the making of gas dissolver, can quickly assemble, reduce assembling consumption
When, reduce running cost.
