清管閥一種高性能球閥，專為惡劣的工業(yè)環(huán)境而設(shè)計，具有多種功能，旨在優(yōu)化管道清潔和維護(hù)。該閥有利于管道清管器的運(yùn)動，有效去除水垢、沉積物和其他雜質(zhì)，保持管道的清潔度和流動效率。
歐菲C型球閥采用雙偏心設(shè)計：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。閥桿在兩個平面上的偏移產(chǎn)生C球旋轉(zhuǎn)+平移的雙矢量凸輪運(yùn)動。閥門關(guān)閉時，C球與閥座產(chǎn)生凸輪楔緊的扭矩密封。扭矩密封的動力來自于手柄、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。
The Cryogenic Temperature and High Performance Butterfly Valve adopts an offset valve stem and eccentric butterfly plate design. When opening and in the middle position, the valve seat and the butterfly plate do not contact each other, which reduces the friction on the valve seat while reducing the torque, and improves the durability of the valve. It is a high-performance regulating and cutting valve. The valve is designed to handle various media that are most difficult to handle in today's industrial environment, including liquid oxygen, liquid natural gas and other cryogenic liquids.
