V-類型球閥：用於不同應用的精確流控制

在工業閥領域中， V-型球閥在其獨特的設計和出色的性能功能方面突出。該專業閥門由於能夠處理具有挑戰性的媒體並提供精確的流量調節，因此已成為各個行業的主食。

設計功能

顧名思義，v-型球閥的定義特徵是球或座椅上的v形缺口。這種V形幾何形狀可以以不同的角度出現，例如15°，30⁰，45⁰，60⁰或90⁰。球通常是四分之一 - 球體，當閥體內旋轉時，V -Notch與座椅相互作用以控制流動區域。閥體可以根據不銹鋼，碳鋼或其他合金等材料來構建，具體取決於應用要求。負責旋轉球的莖可以由PEEK（聚醚 - 乙醚 - 酮）或金屬製成，具有耐用性和對惡劣條件的阻力。

工作機制

V-型球閥的操作相對簡單。可以使用手柄手動啟動它，也可以使用執行器自動啟動。打開閥時，球上的V -Notch的小端開始首先暴露流程路徑。隨著球的進一步旋轉，流動區域隨軸旋轉以線性方式逐漸增加。該線性流量特性是一個重要的優勢，因為它可以非常準確地控制流體流速。為了關閉閥門，球朝相反的方向旋轉，最終將其緊密地密封在座椅上。手柄或執行器的四分之一轉彎足以將閥門從完全開放到完全封閉的閥門，反之亦然。
