nongroove bevel gear knife gate valve

傘齒輪型鑄鐵閥體采用整體式結(jié)構(gòu)刀閘閥，包括閥體、閘板和U型密封條，閥體中腔底部設(shè)有凹槽并裝有彈性U型密封條，當(dāng)閥門(mén)關(guān)閉時(shí)閘板下移，閘板底部邊緣與密封條接觸進(jìn)而壓縮密封條進(jìn)入凹槽中實(shí)現(xiàn)閥體和閘板的密封；當(dāng)?shù)堕l閥開(kāi)啟時(shí)閘板上移，閘板底部邊緣與密封條脫離，密封條彈起與凹槽平整，能防止刀閘閥在使用過(guò)程中，介質(zhì)沉淀物積存在閥體中腔的凹槽里，不易堵塞、無(wú)殘留，管道清洗方便，從而有效提高刀閘閥的密封效果，防止閥門(mén)關(guān)閉時(shí)泄漏。使用壽命更長(zhǎng)，維護(hù)更簡(jiǎn)單；法蘭密封面鑲O型圈，無(wú)須另配法蘭墊片，安裝簡(jiǎn)單方便，磨擦系數(shù)小，啟閉靈活，該系列刀閘閥配傘齒輪傳動(dòng)開(kāi)啟更輕松，以滿足不同工礦要求使用。號(hào)（200620047950.0）

Cast Iron , with the overall structure,bevel gear knife gate valve includes body,disc and U-seal, groove and flexible U-seal at the bottom of the cavity. Disc is moved down when valve is closed, the bottom edge of disc meets with the seal and then compresses into the groove to achieve sealing . Disc is moved up when knife gate valve is opened, the bottom edge of disc breaks from seal. Seal bounces up with groove formation to prevent media accumulated in the body cavity , not blocked easily and residue, pipe is cleaned easily ,and to prevent leakage when knife gate valve is closed .That improves knife gate valve's sealing effect effectively . With longer service life, simply maintenance ,flange O-ring sealing , without changing flange gasket,simply installation and small friction coefficient ,flexibly opening and closing, the series knife gate valve can be equipped with bevel gear to easily open to meet different industrial and mining using.
