style="text-indent:25px">電站截止閥的工作原理：開啟過(guò)程：1在關(guān)閉位置，閥體受閥桿的機(jī)械施壓作用，緊壓在閥座上。2當(dāng)逆時(shí)針轉(zhuǎn)動(dòng)手輪時(shí)，閥桿則反向運(yùn)動(dòng)，其底部角形平面使球體脫開閥座。3閥桿繼續(xù)提升，并與閥桿螺旋槽內(nèi)的導(dǎo)銷相互作用，使球體開始無(wú)摩擦地旋轉(zhuǎn)。4直至到全開位置，閥桿提升到極限位置，球體旋轉(zhuǎn)到全開位置。關(guān)閉過(guò)程：1關(guān)閉時(shí)，順時(shí)針旋轉(zhuǎn)手輪，閥桿開始下降并使球體離開閥座開始旋轉(zhuǎn)。2繼續(xù)旋轉(zhuǎn)手輪，閥桿受到嵌于其上螺旋槽內(nèi)的導(dǎo)銷的作用，使閥桿和閘板同時(shí)旋轉(zhuǎn)90度。3 快要關(guān)閉時(shí)閘體已在與閥座無(wú)接觸的情況下旋轉(zhuǎn)了90度。4手輪轉(zhuǎn)動(dòng)的之后幾圈，閥桿底部的角形平面機(jī)械地楔向壓迫球體，使其緊密地壓在閥座上，達(dá)到完全密封。電站截止閥操作方便，開閉迅速，從全開到全關(guān)只要旋轉(zhuǎn)90度，便于遠(yuǎn)距離的控制。安徽150lb美標(biāo)高壓截止閥</p><p
