Three of the above form is only using the walking path of three kinds of relatively recapitulative fluids as explanation, so that this field
In the case that technical staff can clearly be informed in low pressure, middle pressure, high pressure, the intensity and principle of fluid energy dissipating, to realize
From the purpose of constant current water flow.
During the work time, the effect and principle of energy dissipating are as described below:
1. high pressure water flow passes through energy dissipating block, in addition to generating linear loss, being influenced by the position of energy dissipating block, water flow generates turbulent fluctuation,
Energy, i.e. local head loss are consumed, accounts for 90% of total energy consumption or more；
2. after water flow is by first energy dissipating block energy consumption, accounting is big, and water flow will be by the excessive of periphery streamline if inlet pressure is low
Runner forms certain stream out, at this moment belongs to two-dimensional plane energy dissipating by this structure；
3. after water flow is by first energy dissipating block energy consumption, remaining biggish complementary energy, water flow was removed by week if inlet pressure increases
Side outflow is outer, and water flow will be downwardly into exit passageway by the intercommunicating pore of first energy dissipating block；That is disappearing by second level energy dissipating unit
Energy block, further energy dissipating form certain stream out, belong to three-dimensional three-dimensional energy dissipating.
4. after water flow is by k-th of energy dissipating block energy consumption, remaining biggish complementary energy, water if inlet pressure continues growing
Stream will be downwardly into energy dissipating chamber by the outlet of kth energy dissipating block, and generate reverse flow, in addition to energy consumption 3., increase in energy dissipating chamber
Positive water flow and reverse water flow and blending are added, further energy dissipating increases one-dimensional energy dissipating, belongs to four-dimensional three-dimensional energy dissipating.
In short, with the increase of inlet pressure, water flow turns to higher-dimension energy dissipating by low-dimensional energy dissipating so that the same energy dissipating block with
The raising of inlet pressure, effect of energy dissipation are more and more stronger；Vice versa.
By pressing water inlet pressure adjust automatically water stream channel, to eliminate the extra pressure head of entrance, guarantee
Exit water flow pressure is relatively stable, realizes the effect of outlet pressure and stability of flow under different inlet pressures.
