進口氣動粉體蝶閥專用水泥、粉塵、粉末等物料介質(zhì)的場合，主要由閥體、密封座、閥板和氣動執(zhí)行器組成，閥體橡膠密封圈形成的軟性密封，使其特別適用于磨損性強的物料。在需要重力落料或氣力輸送的粉體，顆粒物料處理系統(tǒng)中，氣動粉體蝶閥常常被安裝在料斗，筒倉，螺旋輸送機出口以及氣送管路上The pneumatic powder butterfly valve is mainly composed of a valve body, a sealing seat, a valve plate, and a pneumatic actuator for materials such as cement, dust, and powder. The soft seal formed by the rubber sealing ring of the valve body makes it particularly suitable for materials with strong wear resistance. In powder and particle material processing systems that require gravity feeding or pneumatic conveying, pneumatic powder butterfly valves are often installed on hoppers, silos, screw conveyor outlets, and pneumatic pipelines

進口氣動粉體蝶閥結(jié)構(gòu)特點 Structural characteristics

氣動粉體蝶閥閥板中間為平板結(jié)構(gòu)，閥桿設(shè)置在閥板的上下兩側(cè)并與閥板一體連接，密封座套接在閥板上，閥板兩側(cè)的閥桿穿過密封座的軸孔容置在閥體的軸孔內(nèi)。氣動粉體蝶閥由粉體板、丁晴密封圈，覆以耐磨高分子材料加工而成，半閥體為鋁合金材料，旋轉(zhuǎn)閥板采用高分子材料制作，專用于粉狀及顆粒狀物料處理。
