襯氟閘閥結(jié)構(gòu)特點：
1.閥體有扁體和圓體兩種形狀：GB閥門采用圓體，ANSI磅級閥門DN≤300Lb采用扁體，DN≥400Lb采用圓體，閥體、閥蓋的內(nèi)腔和閘板、閥桿外表面等直接與介質(zhì)接觸的部件，全部名襯FEP(F46)等氟塑料；
2.密封副為FPF(F46)/ FEP(F46)或其它材料組合，摩擦系數(shù)小，啟閉力矩低；
3.填料采用PTFE(F4)標(biāo)準(zhǔn)填料，密封性能好，維修更換方便；
4.帶有彈性的閘板，可補償閘板密封面與閥座密封面之間楔角偏差，吻合度好，密封效果理想；
5.介質(zhì)可從兩側(cè)任意方向通過閘閥，適用于介質(zhì)方向可能改變的管路上作用啟閉裝置。
