襯氟閘閥結(jié)構(gòu)特點(diǎn):
1.閥體有扁體和圓體兩種形狀:GB閥門(mén)采用圓體,ANSI磅級(jí)閥門(mén)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(bǔ)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(guò)閘閥,適用于介質(zhì)方向可能改變的管路上作用啟閉裝置。
