進(jìn)口不銹鋼刀形閘閥,(德國(guó)OLES閥門(mén))品牌
【進(jìn)口不銹鋼刀形閘閥】特點(diǎn)：
本閥門(mén)為雙閘板單面密封設(shè)計(jì)，有效防止閥腔內(nèi)因*積灰而造成的閥門(mén)開(kāi)關(guān)不到位、卡瑟等現(xiàn)象。閥體采用精密鑄鋼件，密封填料采用耐磨耐高溫氟橡膠密封組件，閥板與閥座間密封面采用耐磨硬質(zhì)合金材料或耐磨增韌結(jié)構(gòu)陶瓷，表面光滑，硬度可達(dá)60~70HRC，解決了密封面因物料沖刷而易被沖蝕、壽命不高的問(wèn)題，使用壽命比普通材料閥門(mén)長(zhǎng)5-10倍，為用戶帶來(lái)理想的使用效果和經(jīng)濟(jì)效益，大大提高了設(shè)備運(yùn)行的安全性、穩(wěn)定性。本閥具有密封性能好、耐磨性強(qiáng)、耐高溫、啟動(dòng)負(fù)荷小、無(wú)卡灰或積灰現(xiàn)象、使用壽命長(zhǎng)等特點(diǎn)。
The valve is designed for single-side sealing with double gate, which can effectively prevent the valve opening from not in place and Cather caused by long-term ash accumulation in the valve chamber. The valve body is made of precise cast steel, the sealing filler is made of wear resistant and high temperature resistant fluororubber sealing assemblies, and the sealing surface between the valve plate and the seat is made of wear resistant cemented carbide or wear resistant and toughened structural ceramics. The surface is smooth and the hardness can reach 60~70HRC. The problem that the sealing surface is easy to be eroded due to material erosion and the service life is not high is solved. Compared with ordinary material valves, the valve is 5-10 times longer, which brings ideal use effect and economic benefits to users, and greatly improves the safety and stability of equipment operation. The valve has the characteristics of good sealing performance, strong wear resistance, high temperature resistance, small start-up load, no stuck or accumulated ash, long service life, etc.
【進(jìn)口不銹鋼刀形閘閥】工作原理:
當(dāng)氣源從上進(jìn)氣口通入時(shí)，閥桿帶動(dòng)閥板向下運(yùn)動(dòng)，閥門(mén)關(guān)閉。當(dāng)氣源從下進(jìn)氣口通入時(shí)，閥桿帶動(dòng)閥板向上運(yùn)動(dòng)，閥門(mén)開(kāi)啟。閥板與閥座之間加載彈簧，彈簧彈力始終使閥板壓向閥座保證閥門(mén)的密封性，又容許閥板在垂直上下方向移動(dòng)，這有助于補(bǔ)償閥門(mén)零件的熱脹冷縮，并能克服任何背壓變化對(duì)密封的影響與防止顆粒介質(zhì)進(jìn)入兩密封面之間。在啟閉過(guò)程中，閥板能產(chǎn)生自轉(zhuǎn)，使得密封面之間產(chǎn)生研磨、拋光作用，而且由于閥體對(duì)通道偏心，在開(kāi)啟排卸物料時(shí)，會(huì)產(chǎn)生渦流，形成的物料旋渦會(huì)自行清掃閥門(mén)內(nèi)腔。此閥門(mén)為雙閘板單面密封，*的下閥體斜面加鏤空下閥板設(shè)計(jì)，保證閥門(mén)內(nèi)腔不積灰。所有的這些特點(diǎn)，使得這種閥門(mén)具有超長(zhǎng)的使用壽命，為您的系統(tǒng)安全運(yùn)行提供了可靠的保證。
【進(jìn)口不銹鋼刀形閘閥】應(yīng)用：
本閥門(mén)主要用于火力發(fā)電企業(yè)的粉煤灰氣力輸送系統(tǒng)中，做倉(cāng)泵進(jìn)料閥、平衡閥、透氣閥、排氣閥、排堵閥，也可用作卸灰閥。同時(shí)也可適用于水泥、礦山、造紙、化工等各類有磨損的干粉塵、水、蒸汽等介質(zhì)在管道上作啟閉之用。
