throttled valve 中文意思是什麼
-
The valve stem with its grooved rings and positioning sleeve indicates the throttled position of the valve
閥桿及其溝槽環和定位套筒顯示閥門的節流位置。 -
Measure and record the differential pressure across the valve in the throttled position
測量和記錄通過處于節流位置的閥門的壓差。 -
As a general rule, an adequately sized globe valve ( i. e. with pipe velocity between 15 to 25 ft / sec for water and 200 to 300 ft / sec for steam ) should not be throttled down below 35 % of its maximum full open cv capacity ( approximately 20 % of full stroke )
一般而言，通徑足夠大的截止閥（例如管道內水流速度在15至25英尺/秒之間，蒸汽流速在200至300英尺/秒之間） ，節流后的流量不應該小於完全開啟狀態流量（流量系數大約為全沖程的20 % ）的35 %以下。 -
To calculate flow rate of valve in the throttled position, multiply the flow rate from step 6. 3. 4 by the percentage flow rate from step 6. 3. 2 divided by 100
為了計算處于節流位置的閥門的流量，將從步驟6 . 3 . 4得到的流量乘以叢步驟6 . 3 . 2得到的百分比流量，再除以100 。
