low water valve 中文意思是什麼
low water valve
解釋
低水位閥-
The product adopts the infalling through system on the structure of boiler pipe line, if equips safely valve an will stop working automatically in case hyperthermal, super - pressure and low water lever
安全採用水管貫流式爐膽結構，並配備安全閥，溫度過熱，水位過低，壓力過高等四重保護，絕對安全可靠。 -
After simulating the model of water hydraulic valves, the velocity distribution, pressure distribution, energy distribution can be obtained and relations between the valve channel and the energy loss, the negative pressure distribution can be analyzed, which offers the theory foundation for designing water hydraulic valves with the high efficiency, low energy loss and low noise
通過對水壓閥模型的cfd穩態和瞬態解析，可以得到水壓閥內流場的速度分佈、壓力分佈及能量分佈，據此定性分析流道結構（速度、壓力、流動的分離與再附壁，旋渦的產生與消失等）與能量損失、負壓分佈等的關系，從而為設計出高效率、低能耗、低噪聲的水壓閥提供理論依據。 -
The results show that, when the compressor continuously runs, the stability of the test bed after using manual valve is better than that of using thermal valve, and it is little affected by the kinds of valves for adjusting cooling water ; and that, when the compressor intermittently runs, the operation stability would be obtained if pneumatic valve is used to adjust cooling water, especially at low speed
結果表明，壓縮機連續運行時，製冷劑採用手動閥調節后工況的穩定性明顯好於採用熱力膨脹閥時的情況，此時調節冷卻水量用的電動調節閥和氣動調節閥對工況穩定性影響相差無幾；間歇運行時，無論是熱力膨脹閥還是手動閥，即便壓縮機通電時間最長，仍達不到設定工況，特別是低速的斷續尤為明顯，而使用氣動閥就能很好地解決這一問題。 -
