● 閥座活塞效應(yīng)。能提供3種組合的活塞效應(yīng):一、上下游都是單活塞效應(yīng)閥座,即DBB功能;二、上下游都是雙活塞效應(yīng)閥座,即DIB-1功能;三、上游是單活塞效應(yīng)閥座,下游是雙活塞效應(yīng)閥座,即DIB-2功能;
● 閥座與球體之間密封有兩種結(jié)構(gòu):一為傳統(tǒng)的軟密封結(jié)構(gòu),二為三角圈密封結(jié)構(gòu);
● 閥桿為防噴設(shè)計,可防止因操作不當而造成閥桿從閥體里噴出;
● 具有防火防靜電裝置;
● 閥座密封和閥桿密封處設(shè)計有緊急密封脂注入口。正常的密封不依賴密封脂。當密封面損傷而引起泄露時,可注入密封脂緊急修復。每個注脂孔口安裝個注脂閥和一個內(nèi)嵌的單向閥。
● 排污口與放空口。在閥體最低位置安裝有排污閥,可對閥腔放空和排污;在閥體上部安裝有放空閥,可在線對閥腔進行放空和清洗。排污閥和放空閥可以是隔離閥或?qū)S门欧沤宇^,確保安全可靠,方便使用。
● 能夠配套各種驅(qū)動裝置的連接盤。驅(qū)動裝置包括手柄、蝸輪、電動、氣動、氣液聯(lián)動、電液聯(lián)動等
● 對于端部為焊連接的閥門,可以根據(jù)用戶管道材質(zhì)等級響應(yīng)調(diào)整閥門端部材質(zhì)(過渡段),以保證材質(zhì)強度的適配性和可焊性。兩端加袖管的閥門,袖管的長度能保證現(xiàn)場焊接操作對密封材料不產(chǎn)生影響;
● 埋地設(shè)計。埋地安裝的閥門,閥桿根據(jù)工程的需要加長,以便地上操作,并將相應(yīng)的注脂、排污和放空裝置由管子引伸至地上。

The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
