DBB單法蘭針閥:工業流體系統中的精確控制器

在工業流體控制的領域中,DBB(雙塊和出血)單法蘭針閥是一種精確的儀器,將復雜的設計與強大的功能相結合,以確保准確的流量調節和增強的系統安全性
DBB單法蘭針閥的結構是工程精度的奇蹟。它具有帶有單個法蘭連接的閥體,這簡化了管道系統的安裝。其核心是一個細長的錐形針狀閥莖,適合匹配的座椅,可以進行精細的調整。雙塊和出血函數是通過兩個獨立的密封元件和一個出血端口實現的。該設計使閥門能夠隔離管道的上游和下游部分(雙塊),並釋放密封之間的任何被困壓力(出血),從而增加了額外的安全層。

該閥的工作原理圍繞精確控制。當手輪旋轉時,閥桿軸向移動。將手輪順時針旋轉將針頭推入座椅,減少流動區域並限制中等流動。相反,旋轉手輪逆時針會縮回針頭,增加流動區域並允許更多的培養基通過。在維護或緊急情況下,雙塊和出血機制發揮了作用:關閉兩個密封件可以隔離系統,並打開流血端口可減輕任何殘留壓力,以防止意外發行
DBB單法蘭針閥在石油和天然氣,化學加工和藥品等行業中發現了廣泛的用途,在這些行業中,精確的流量控制和系統安全至關重要。它們在涉及高壓,有毒或易燃媒體的應用中特別有價值,即使是輕微的洩漏或不當隔離也可能導致嚴重的後果。無論是在採樣系統,儀表線還是過程控制循環中,這些閥可提供一致可靠的性能
它們的主要優勢之一是流量調節中的出色精度,可以進行微小的調整以滿足特定的流程要求;雙塊和流血功能,可以增強操作安全性並簡化維護;以及單個法蘭設計,可確保與管道的安全無洩漏連接。此外,它們的緊湊尺寸使其適合在狹窄的空間中安裝,而不會損害性能
從本質上講,DBB單法蘭針閥是高精度工業流體系統中必不可少的組件,提供精確的控制,健壯的安全功能和可靠的操作來保護過程和人員。
