進口大口徑鍛造閥門,(德國奧萊斯OLES閥門)
【進口大口徑鍛造閥門】詳細說明：
是經整體鍛造的高壓閘閥，口徑可以從1/2寸到24寸，即DN600.主要用于 Class150 ～ 4500 、工作溫度 -29～425℃（碳鋼）或 -29～580℃（不銹鋼、鉻鉬鋼）的火電廠蒸汽管路上，用于截斷或接通管路中的介質。選用不同的材質，也可以適用于水、蒸汽、油品、二、進口大口徑高溫高壓閘閥結構形式進口大口徑高溫高壓閘閥閘板有兩個密封面,zui常用的模式閘板閥的兩個密封面形成楔形、楔形角隨閥門參數(shù)而異,通常為50,介質溫度不高時為 2°52'。楔式閘閥的閘板可以做成一個整體,叫做剛性閘板;也可以做成能產生微量變形的閘板,以改善其工藝性,彌補密封面角度在加工過程中產生的偏差,這種閘板叫做彈性閘板。進口大口徑高溫高壓閘閥具有自密封功能，即壓力越高，密封性能越好
It is a forged high-pressure gate valve with diameters ranging from 1/2 inch to 24 inch, i.e. DN600. It is mainly used in steam pipelines of thermal power plants with Class150-4500, working temperature-29-425 C (carbon steel) or-29-580 C (stainless steel, chromium-molybdenum steel), for cutting off or connecting the medium in the pipelines. Choosing different materials can also be applied to water, steam, oil products, second and imported large caliber high temperature and high pressure gate valve structure. The gate plate of imported large caliber high temperature and high pressure gate valve has two sealing surfaces. The two sealing surfaces of Zui common mode gate valve form wedge shape and wedge angle which vary with the valve parameters, usually 50, when the medium temperature is not high. It is 2 degree 52'. Wedge gate valve can be made into a whole, called rigid gate; it can also be made into a gate that can produce slight deformation to improve its workability, make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called elastic gate. Imported large caliber high temperature and high pressure gate valve has self-sealing function, that is, the higher the pressure, the better the sealing performance.
【進口大口徑鍛造閥門】特點：
大口徑閥門主要適用于火力電站各種系統(tǒng)的管路上，切斷或接通管路介質。適用介質:水、蒸氣等非腐蝕性介質。高壓閥門與其他閥門產品相比的特點是高溫高壓，*的自密封設計，壓力越高，密封越可靠。由于性能技術特性、工況的特殊使產品也形成了其他產品所替代不了的特點。大口徑高壓球閥常常忽視注脂量的問題。注脂槍加油后，操作人員低溫截止閥選擇閥門和注脂聯(lián)結方式后，進行注脂作業(yè)。存在著二高壓閘閥種情況:一方面注脂量少注脂不足，密封面因缺少潤滑劑而加快磨損。另一方面注脂過量，造成浪費。在于沒有根據閥門類型類別，對不同的閥門密封容量進行精確的計算?？梢砸蚤y門尺寸和類別算出密封容量，再合理的注入適量的潤滑脂。
