進(jìn)口手輪刀形閘閥(德國奧萊斯OLES閥門)
【進(jìn)口手輪刀形閘閥】詳細(xì)說明：
刀型閘閥是閘閥的一種，是直行程切斷閥門，刀閘閥的閥板頭部有斜刃口，對介質(zhì)具有一定的切斷作用，適合用于含纖維及固體顆粒介質(zhì)及污水處理系統(tǒng)中，可佩手動，氣動，電動執(zhí)行器，廣泛使用于造紙，采礦，化工，污水處理等過程自控系統(tǒng)中。主要由閥體、閥板、絲桿、閥桿螺母、支架、壓條、手輪、填料組成，具有體積小，重量輕，本產(chǎn)品屬單夾式梅花型、平行單閘板結(jié)構(gòu)、單向流通性質(zhì)，流通阻力小、可切斷各種漿類、灰渣、污水、水渣混合物、纖維等介質(zhì)，廣泛應(yīng)用于電力，市政、礦山、冶金、化工、煤炭、水利等行業(yè)，是一種應(yīng)用性強(qiáng)的新型更新替代閥門產(chǎn)品。
可提升的閘板密封面，可刮除密封面上的粘著物，自動清除雜物；不銹鋼閘板可防止腐蝕引起的密封泄漏；短結(jié)構(gòu)長度，可節(jié)省原料、安裝空間、也有效支持管道強(qiáng)度；閥體上的導(dǎo)向塊使閘板正確運(yùn)動。擠壓塊保證閘板有效密封；U型閘板可作為切斷使用。
Knife gate valve is a kind of gate valve. It is a straight-stroke cut-off valve. The head of the valve plate of knife gate valve has an oblique edge, which has a certain cut-off effect on the medium. It is suitable for medium containing fibre and solid particles and sewage treatment system. It can be used with manual, pneumatic and electric actuators. It is widely used in papermaking, mining, chemical industry and sewage treatment. Processing and other process automatic control system. It is mainly composed of valve body, valve plate, screw rod, valve stem nut, bracket, press bar, handwheel and packing. It has small volume and light weight. It belongs to single clip plum blossom type, parallel single gate structure, one-way flow property, low flow resistance, and can cut off all kinds of slurry, ash, sewage, water-slag mixture, fiber and other media. Widely used in electric power, municipal, mining, metallurgy, chemical industry, coal, water conservancy and other industries, is a new type of renewal replacement valve products with strong application.
Liftable gate sealing surface can scrape off the adhesion on the sealing surface and automatically remove debris; stainless steel gate can prevent sealing leakage caused by corrosion; short structure length can save raw materials, installation space and effectively support pipeline strength; guide block on the valve body can make the gate move correctly. The extrusion block ensures the effective sealing of the gate; the U-shaped gate can be used as a cut-off.
【進(jìn)口手輪刀形閘閥】特點(diǎn)：
1、閥門采用整體式設(shè)計(jì)，，流體阻力小，操作靈活方便。 2、手動刀閘閥螺桿傳動采用雙平面軸承設(shè)計(jì)，使得傳動摩擦力大大減少，從而閥門開啟輕便順暢。 3、刀閘閥密封座采用可動式密封，且采用O形圈預(yù)緊提供預(yù)緊力使密封座緊貼閥瓣，泄露量大大減少，對在*使用中密封副的磨損有自動補(bǔ)償功能提高了使用壽命。 4、固定導(dǎo)向爪，無凹槽設(shè)計(jì)，不易引起介質(zhì)積存或卡阻。 5、閥座可根據(jù)介質(zhì)和工況的需要，選擇金屬硬密封或軟密封：閘板采用表面鍍鉻或離子氮化處理，使閘板更耐磨，密封面使用壽命更長；軟密封可選PTFE閥座或增強(qiáng)PTFE閥座或三元乙丙、丁晴橡膠，密封性好，耐腐蝕。 6、介質(zhì)適應(yīng)范圍廣：良好的密封性能和經(jīng)濟(jì)實(shí)用性強(qiáng)，操作可手動、氣動、電動，實(shí)用范圍非常廣。
【進(jìn)口手輪刀形閘閥】工作原理：
手動刀形閘閥采用整體式結(jié)構(gòu)，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)閥門關(guān)閉時閘板下移，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閥開啟時閘板上移，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程中，介質(zhì)沉淀物積存在閥體中腔的凹槽里，不易堵塞、無殘留，管道清洗方便，從而有效提高刀閘閥的密封效果，防止閥門關(guān)閉時泄漏。
