通氣孔閥 的英文怎麼說
中文拼音 [tōngqìkǒngfá]
通氣孔閥
英文
air vent valve-
By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve
通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現,固定閥周圍流場存在較強的湍動,閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區,使氣體穿閥后的行為變得復雜,並對氣液傳質過程產生重大影響;模擬結果表明,為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響,通過折邊來改變氣體的氣路是非常有效的,模擬值與實驗值基本得到吻合。The structure and operating principle of an air - charged split - type adjustable shock absorber was described, e non - linear parameterized mathematical model of this shock absorber ' s damping characteristics was established according to fluid mechanics theory and the main structural affection factors to shock absorber ' s damping performance, such as the diameter of piston valve orifice, the diameter of adjustable orifice, the initial volume of gas chamber, the diameter of piston rod, the inner diameter of oil pipe and so on, were analyzed by simulations
摘要通過分析一種分體式充氣可調阻尼減振器的結構和工作原理,運用流體力學理論,建立了該減振器阻尼特性的非線性參數化模型,模擬分析了活塞阻尼閥孔徑、阻尼調節孔徑、氣室初始體積、活塞桿直徑、油管內徑等主要結構參數對減振器阻尼性能的影響,通過試驗測試,得到了減振器樣件的阻尼特性及其可調范圍。Control valve breather
控制閥通氣孔Abstract : to ensure the pressure tightness requirements of the 120 valve ' s pressing - bushed fit, through the analysing the fit tolerance of three kinds of valve bushes and bodies, we determined to raise the tolerance of hole and body from h9 to h8
文摘:為確保120閥壓套配合的氣密性要求,通過對3種閥套與閥體配合公差的分析,確定將體孔公差由h9提高到h8 。In the swirl, air stream at the periphery tend to have higher temperature compared to that in the center. by means of a separating plate, the airflow is separated into streams of hot and cold air. each stream of air then emerges from a particular end of the tube, named the cold and hot end accordingly
氣體在熱端管的流動過程中,外層氣流溫度升高,內層返流溫度降低,高溫氣流從熱端閥流出,低溫氣體通過冷孔板流出,從而將進渦流管的氣流分離為冷熱兩股溫度不同的氣流。This machine is a kind of radial riveting machine, the machine adopted the advanced radial technology, and its movement path likes the 11 pieces of plum blossom s shape, and using the screw pole to ascend and descend the work bench the head part is fixed, and the t - slot of bench can fix the clamping apparatus available, the center hole of bench and axis are coaxial, the one - way adjusting valve of liquid current is effectively controlled riveting speed
