三通球閥可以是 L型或T型。L型三通球閥具有一個入口和一個出口，第三口用作旁通；T型三通球閥具有兩個進口和一個出口，或一個進口和兩個出口。三通球閥常用于需要改變流向或旁路操作的管道系統(tǒng)，如化工、石油、天然氣和供水系統(tǒng)。多通球閥可以控制多個管道中流體的流動方向，允許在一個閥門上進行多種操作，如分配、混合或隔離流體。多通球閥適用于需要精確控制流體分布的復雜管道系統(tǒng)，如石油煉制、化工加工、多產品管道輸送等。
◎ 主體材質：碳鋼，不銹鋼，合金鋼。
◎ 公稱通徑：2"~24"DN50~600

◎ 驅動方式：手動、蝸桿、氣動、電動等。
◎ 應用范圍：廣泛應用于石油、化工、制藥等行業(yè)的生產設備。在這些行業(yè)中，三通及多通球閥可用于調節(jié)系統(tǒng)中各種管道的啟閉或流量控制。例如，在石油化工生產過程中，三通及多通球閥可以控制不同油品的混合比例，以滿足生產需要。在制藥工業(yè)中，三通及多通球閥用于精確控制藥液的流向和流量，以確保藥品的質量和安全。在紡織、食品等行業(yè)中，三通及多通球閥在控制介質流量、分配流體、添加物料等方面也起著重要作用。
Flat gate valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
