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.
三通及多通球閥是流體控制系統(tǒng)的重要部件，廣泛應(yīng)用于各個(gè)工業(yè)領(lǐng)域。它們是球閥的變種。它們的設(shè)計(jì)允許流體在兩個(gè)以上的管道之間分配或轉(zhuǎn)換。三通球閥有三個(gè)接口，可以實(shí)現(xiàn)流體的分流、合流或切換。根據(jù)內(nèi)部結(jié)構(gòu)的不同，分為L型和T型。L型只能連接兩根相互正交的管道，不能同時(shí)保持第三根管道的互聯(lián)，只起分配作用；T型可使三根正交管相互連通，切斷第三道，起到導(dǎo)流合流的作用。多通球閥是三通球閥的延伸，具有更多的接口和更復(fù)雜的流體控制功能。
歐菲C型球閥采用雙偏心設(shè)計(jì)：C球回轉(zhuǎn)中心（軸心）與C球密封面幾何中心（球心）、C球回轉(zhuǎn)中心與閥座密封中心的雙偏心設(shè)計(jì)。閥桿在兩個(gè)平面上的偏移產(chǎn)生C球旋轉(zhuǎn)+平移的雙矢量凸輪運(yùn)動(dòng)。閥門關(guān)閉時(shí)，C球與閥座產(chǎn)生凸輪楔緊的扭矩密封。扭矩密封的動(dòng)力來自于手柄、齒輪、執(zhí)行機(jī)構(gòu)，從機(jī)械原理上確保不依賴彈簧或工藝壓力而實(shí)現(xiàn)嚴(yán)密關(guān)斷。
