進口自力式壓差控制閥
名稱:進口自力式壓差控制閥 型號:Regus 口徑:DN15-300 壓力:1.0-2.0mpa 材質:WCB、304、316
英國Regus雷格斯進口自力式壓差控制閥
自力式壓差控制閥不需外來能源依靠被控介質自身壓力變化進行自動調節,自動消除管網的剩余壓頭及壓力波動引起的流量偏差恒定用戶進出口壓差,有助于穩定系統運行,特別適用分戶計量或自動控制系統中。
英國Regus雷格斯進口自力式壓差控制閥的定義
壓差控制閥一般安裝在用戶入口回水管上,閥下導壓管與入口處供水管相接,P1為供水壓力,P2為閥內回水壓力,P3為閥外回水壓力。
設閥內系統壓差△Pi(△Pi=P1-P2)為閥門壓差設定值時,閥門下膜室壓力P1與P2加上彈簧被壓縮變形產生的推力相平衡,從而確定了流體流過閥門的流通截面積A和流量系數。當流量改變時,上述力的平衡使閥門的流通截面積A和流量系數發生變化,但△Pi保持不變。
當流體性質、管徑、流量阻力系數確定后,單管阻力計算公式可近似寫為:
△P=Kqm2
式中:△P-----管路總阻力;
K-------管路阻抗;
qm----流量。
由上式可知管路阻力與質量流量的二次方及管路阻抗成正比。當流量變化時使上膜室壓力P2變化導致閥芯上下移動,使A及相應的流量系數均改變來調整閥內系統總阻力的變化,使△Pi基本保持不變。
