To on the contrary, obvious shaving effect therefore can be produced.Described shaving effect, refers to the high-speed gas of entrained drip outside
When cylinder inwall rotation is flowed up, it is straight that drop is constantly thrown toward the big drop carried secretly in outer, gas in the presence of inertia force
Connect the tooth bottom for being dumped into internal thread and threadingly line goes downstream；The smaller droplet and the odontogenesis of internal thread carried secretly in gas are hit
Hit, and be attached on the tooth of internal thread, the gas of entrained drip and the striking face of outer barrel are significantly increased due to internal thread, is made small
Drop constantly assembles change and forms big drop greatly, and then threadingly line goes downstream；Because the thread height of internal thread is smaller, therefore
When the odontogenesis of gas and internal thread is hit, only change the flow direction of local gas, the overall flow trend on gas has no influence,
Therefore gas continues to keep to flow up along outer tube inner wall rotation at a high speed, so that third time realizes gas-liquid separation.By above-mentioned
Rectification, acceleration and shaving effect, make fluid realize the separation of drop and gas in flow process.
