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)閘體已在與閥座無接觸的情況下旋轉(zhuǎn)了90度。 4、手輪轉(zhuǎn)動(dòng)的ZUI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。</p><p
