free flow valve 中文意思是什麼
free flow valve
解釋
易流閥-
Then pid flow rate control algorithm is introduced. all experiments made in this chapter are about measuring the valve parameters according to spool positions, single actuator flow rate control by the calculated flow rate feedback control method, free flow rate dividing control under the sufficient pump discharge flow rate situation, proportion flow rate dividing and flow rate dividing based on meter - in flow rate feedback control method under insufficient pump discharge flow rate situation. the results of all experiments proved that the method presented in this thesis is an effective way to overcome the unreasonable flow rate dividing when simultaneously operating multi - actuators with different inertia loads
第四章介紹了多執行器復合控制實驗系統和實驗方法；介紹了實驗採用的流量控制的pid演算法；並測定了執行器控制閥和閥芯位移相關的系數；做了單個執行器計算流量反饋流量控制、流量足夠情況下多執行器流量任意分配、流量不足情況下多執行器按比例調節流量分配和多執行器進油側流量反饋分流控制實驗；通過實驗說明了論文提出的分流控制方法能實現大小慣性負載復合操作時的合理分流。 -
Placing a check valve in the opposite direction to the flow will prevent the disc from swinging free and will therefore prevent normal operation of the valve
如果止回閥安裝方向錯誤，閥瓣就無法正常旋啟，閥門的作用也無法正常發揮。 -
The valve stem is not connected to the disc, and when the stem is in the open position then the disc is free to respond to the flow
這種閥的閥桿並不連接到閥瓣上，當閥桿處于開啟位置時，閥瓣可以根據流體流向自動進行調節。
